1-[3-(4-bromo-2-methyl-2H-pyrazol-3-yl)-4-methoxy-phenyl]-3-(2,4-difluoro-
-phenyl)-urea or pharmaceutically acceptable salts, hydrates or
solvates thereof. The term "comprising" means "including, but not
limited to." The term "consisting essentially of" means the method
or composition includes the steps or components specifically
recited, and may also include those that do not materially affect
the basic and novel characteristics of the present invention. The
term "consisting of" means the method or composition includes only
the steps or components specifically recited. It must be noted
that, as used herein, and in the appended claims, the singular
forms "a", "an" and "the" include plural reference unless the
context clearly dictates otherwise.
[0022] As used herein, the term "about" means plus or minus 10% of
the numerical value of the number with which it is being used.
Therefore, about 50% means in the range of 45%-55%.
[0023] "Optional" or "optionally" may be taken to mean that the
subsequently described structure, event or circumstance may or may
not occur, and that the described includes instances where the
event occurs and instances where it does not.
[0024] "Administering" when used in conjunction with a therapeutic
means to administer a therapeutic directly or indirectly into or
onto a target tissue to administer a therapeutic to a patient
whereby the therapeutic positively impacts the tissue to which it
is targeted. "Administering" a composition may be accomplished by
oral nasal, sublingual, buccal, transdermal, vaginal or rectal
administration, injection, infusion, inhalation, absorption or by
any method in combination with other known techniques.
"Administering" may include the act of self-administration or
administration by another person such as a health care
provider.
[0025] The term "improves" is used to convey that the present
invention changes the appearance, form, characteristics, structure,
function and/or physical attributes of the tissue to which it is
being provided, applied or administered. "Improves" may also refer
to the overall physical state of an individual to whom an active
agent has been administered. For example, the overall physical
state of an individual may "improve" if one or more symptoms of the
disease, condition or disorder are alleviated by administration of
an active agent.
[0026] As used herein, the term "therapeutic" means an agent
utilized to treat, combat, ameliorate or prevent an unwanted
disease, condition or disorder of a patient.

and methods may be utilized with or on a subject in need of such
treatment, which may also be referred to as "in need thereof." As
used herein, the phrase "in need thereof" means that the subject
has been identified as having a need for the particular method or
treatment and that the treatment has been given to the subject for
that particular purpose.
[0028] As used herein, the term "patient" and "subject" or
"individual" are interchangeable and may be taken to mean any
living organism, which may be treated with compounds of the present
invention. As such, the terms "patient" and "subject" may include,
but are not limited to, any non-human mammal, primate or human. In
some embodiments, the "patient" or "subject" is an adult, an
elderly adult, child, infant, or fetus. In some embodiments, an
elderly adult is an adult of about 50 years of age or older. In yet

that elicits the biological or medicinal response in a tissue,
system, animal, individual or human that is being sought by a
researcher, veterinarian, medical doctor or other clinician, which
includes one or more of the following: (1) Preventing the disease;
for example, preventing a disease, condition or disorder in an
individual that may be predisposed to the disease, condition or
disorder but does not yet experience or display the pathology or
symptomatology of the disease, (2) Inhibiting the disease; for
example, inhibiting a disease, condition or disorder in an
individual that is experiencing or displaying the pathology or
symptomatology of the disease, condition or disorder (i.e.,

-phenyl)-urea or a pharmaceutically acceptable salt, hydrate,
polymorph, or solvate thereof is about 20 mg, about 40 mg, or about
80 mg.
[0030] The term "treating" may be taken to mean prophylaxis of a
specific disorder, disease or condition, alleviation of the
symptoms associated with a specific disorder, disease or condition
and/or prevention of the symptoms associated with a specific
disorder, disease or condition. In some embodiments, the term
refers to slowing the progression of the disorder, disease or
condition or alleviating the symptoms associated with the specific
disorder, disease or condition. In some embodiments, the term
refers to alleviating the symptoms associated with the specific
disorder, disease or condition. In some embodiments, the term
refers to alleviating the symptoms associated with the specific
disorder, disease or condition. In some embodiments, the term
refers to restoring function which was impaired or lost due to a
specific disease, disorder or condition.
[0031] "In Need Of Prophylaxis Or Treatment" as used herein refers
to a judgment made by a caregiver (e.g. physician, nurse, nurse
practitioner, etc. in the case of humans; veterinarian in the case
of animals, including non-human mammals) that an individual or
animal requires or will benefit from prophylaxis or treatment. This
judgment is made based on a variety of factors that are in the
realm of a caregiver's expertise, but that includes the knowledge
that the individual or animal is ill, or will be ill, as the result
of a disease, condition or disorder that is treatable by the
compounds of the invention. In general, "in need of prophylaxis"
refers to the judgment made by the caregiver that the individual
will become ill. In this context, the compounds of the invention
are used in a protective or preventive manner. However, "in need of
treatment" refers to the judgment of the caregiver that the
individual is already ill; therefore, the compounds of the present
invention are used to alleviate, inhibit or ameliorate the disease,
condition or disorder.
[0032] The term "pharmaceutical composition" shall mean a
composition including at least one active ingredient, whereby the
composition is amenable to investigation for a specified,
efficacious outcome in a mammal (for example, without limitation, a
human). Those of ordinary skill in the art will understand and
appreciate the techniques appropriate for determining whether an
active ingredient has a desired efficacious outcome based upon the
needs of the artisan. A pharmaceutical composition may, for
example, contain
1-[3-(4-bromo-2-methyl-2H-pyrazol-3-yl)-4-methoxy-phenyl]-3-(2,4-difluoro-
-phenyl)-urea or pharmaceutically acceptable salts, hydrates or
solvates thereof as the active ingredient. Alternatively, a
pharmaceutical composition may contain
1-[3-(4-bromo-2-methyl-2H-pyrazol-3-yl)-4-methoxy-phenyl]-3-(2,4-difluoro-
-phenyl)-urea or pharmaceutically acceptable salts, hydrates or
solvates thereof as the active ingredient.
[0033] "Pharmaceutically acceptable salts, hydrates or solvates" is
meant to indicate those salts, hydrates or solvates which are,
within the scope of sound medical judgment, suitable for use in
contact with the tissues of a patient without undue toxicity,
irritation, allergic response and the like, and are commensurate
with a reasonable benefit/risk ratio. Pharmaceutically acceptable
salts are well known in the art. For example, Berge et al. (1977)
J. Pharm. Sciences, Vol 6. 1-19, describes pharmaceutically
acceptable salts in detail. A pharmaceutical acceptable "salt" is
any acid addition salt, preferably a pharmaceutically acceptable
acid addition salt, including, but not limited to, halogenic acid
salts such as hydrobromic, hydrochloric, hydrofloric and hydroiodic
acid salt; an inorganic acid salt such as, for example, nitric,
perchloric, sulfuric and phosphoric acid salt; an organic acid salt
such as, for example, sulfonic acid salts (methanesulfonic,
trifluoromethan sulfonic, ethanesulfonic, benzenesulfonic or
p-toluenesufonic, acetic, malic, fumaric, succinic, citric, benzoic
gluconic, lactic, mandelic, mucic, pamoic, pantothenic, oxalic and
maleic acid salts; and an amino acid salt such as aspartic or
glutamic acid salt. The acid addition salt may be a mono- or
di-acid addition salt, such as a di-hydrohalogic, di-sulfuric,
di-phosphoric or di-organic acid salt. In all cases, the acid
addition salt is used as an achiral reagent which is not selected
on the basis of any expected or known preference for the
interaction with or precipitation of a specific optical isomer of
the products of this disclosure.

[0035] "Composition" shall mean a material comprising at least two
compounds or two components; for example, and without limitation, a
Pharmaceutical Composition is a Composition comprising a compound
of the present invention and a pharmaceutically acceptable
carrier.
[0036] "Compound Efficacy" shall mean a measurement of the ability
of a compound to inhibit or stimulate receptor functionality, as
opposed to receptor binding affinity.
[0037] "Constitutively Activated Receptor" shall mean a receptor
subject to constitutive receptor activation.
[0038] "Constitutive Receptor Activation" shall mean stabilization
of a receptor in the active state by means other than binding of
the receptor with its endogenous ligand or a chemical equivalent
thereof.
[0039] "Contact" or "Contacting" shall mean bringing the indicated
moieties together, whether in an in vitro system or an in vivo
system. Thus, "contacting" a 5-HT.sub.2A receptor with a compound
of the invention includes the administration of a compound of the
present invention to an individual, preferably a human, having a
5-HT.sub.2A receptor, as well as, for example, introducing a
compound of the invention into a sample containing a cellular or
more purified preparation containing a 5-HT.sub.2A receptor.
[0040] "Endogenous" shall mean a material that a mammal naturally
produces. Endogenous in reference to, for example and without
limitation, the term "receptor" shall mean that which is naturally
produced by a mammal (for example, and without limitation, a human)
or a virus.
[0041] In contrast, the term "Non-Endogenous" in this context shall
mean that which is not naturally produced by a mammal (for example,
and without limitation, a human) or a virus. For example, and
without limitation, a receptor which is not constitutively active
in its endogenous form, but when manipulated becomes constitutively
active, is most preferably referred to herein as a "non-endogenous,
constitutively activated receptor." Both terms can be utilized to
describe both "in vivo" and "in vitro" systems. For example, and
without limitation, in a screening approach, the endogenous or
non-endogenous receptor may be in reference to an in vitro
screening system. As a further example and without limitation,
where the genome of a mammal has been manipulated to include a
non-endogenous constitutively activated receptor, screening of a
candidate compound by means of an in vivo system is viable.
[0042] "Inhibit" or "Inhibiting", in relationship to the term
"response" shall mean that a response is decreased or prevented in
the presence of a compound as opposed to in the absence of the
compound.
[0043] "Inverse Agonists" shall mean moieties that bind the
endogenous form of the receptor or to the constitutively activated
form of the receptor, and which inhibit the baseline intracellular
response initiated by the active form of the receptor below the
normal base level of activity which is observed in the absence of
agonists or partial agonists, or decrease GTP binding to membranes.
Preferably, the baseline intracellular response is inhibited in the
presence of the inverse agonist by at least 30%, more preferably by
at least 50%, and most preferably by at least 75%, as compared with
the baseline response in the absence of the inverse agonist.
[0044] "Ligand" shall mean an endogenous, naturally occurring
molecule specific for an endogenous, naturally occurring
receptor.
[0045] As used herein, the terms "Modulate" or "Modulating" shall
mean to refer to an increase or decrease in the amount, quality,
response or effect of a particular activity, function or
molecule.
[0046] Before the present compositions and methods are described,
it is to be understood that this invention is not limited to the
particular processes, compositions, or methodologies described, as
these may vary. Moreover, the processes, compositions, and
methodologies described in particular embodiments are
interchangeable. Therefore, for example, a composition, dosages
regimen, route of administration, and so on described in a
particular embodiment may be used in any of the methods described
in other particular embodiments. It is also to be understood that
the terminology used in the description is for the purpose of
describing the particular versions or embodiments only, and is not
intended to limit the scope of the present invention which will be
limited only by the appended claims. Unless defined otherwise, all
technical and scientific terms used herein have the same meanings
as commonly understood by one of ordinary skill in the art.
Although any methods similar or equivalent to those described
herein can be used in the practice or testing of embodiments of the
present invention, the preferred methods are now described. All
publications and references mentioned herein are incorporated by
reference. Nothing herein is to be construed as an admission that
the invention is not entitled to antedate such disclosure by virtue
of prior invention.

has adopted a number of terms to refer to ligands having various
effects on receptors. For clarity and consistency, the following
definitions will be used throughout this patent document.
[0048] "Agonists" shall mean moieties that interact and activate
the receptor, such as the 5-HT.sub.2A receptor, and initiate a
physiological or pharmacological response characteristic of that
receptor. For example, when moieties activate the intracellular
response upon binding to the receptor, or enhance GTP binding to
membranes.
[0049] The term "Antagonists" is intended to mean moieties that
competitively bind to the receptor at the same site as agonists
(for example, the endogenous ligand), but which do not activate the
intracellular response initiated by the active form of the
receptor, and can thereby inhibit the intracellular responses by
agonists or partial agonists. Antagonists do not diminish the
baseline intracellular response in the absence of an agonist or
partial agonist.

[0253] Prophylaxis and/or Treatment of REM Sleep Behavior
Disorder
[0254] The normal sleep cycle is divided into 5 stages: Non-REM
Stage 1, Non-REM Stage 2, Non-REM Stage 3, Non-REM Stage 4, and
REM. Table 5 summarizes the characteristics of each stage.
TABLE-US-00005 TABLE 5 Sleep Stages Sleep Disorder Stage
Characteristics Time spent Associated with Stage Awake Eyes open,
responsive to 16-18 hours Narcolepsy Hallucinations (stage 0)
external stimuli, can hold per day intelligible conversation
Non-REM 4-7 hours Insomnia NREM-related per night parasomnias:
confusional arousals, sleep terror, somnambulism (sleepwalking)
*Stage 1- light Transition between waking sleep and sleep, if
awakened person will claim not asleep *Stage 2- light Main body of
light sleep sleep *Stage 3 & 4- Slow (delta) waves on EEG deep
sleep readings, deepest and most restorative sleep REM* Brain waves
similar to 90-120 minutes REM Sleep Behavior Disorder (Rapid Eye
waking, most vivid dreams per night Movement) happen in this stage,
body paralyzed *Cycle through 5 stages each night
[0255] Distinct Sleep Disorders are associated with Non-REM and
REM, each with distinct pathophysiology. For example, somnambulism
(sleepwalking) and related disorders are not related to dream
enactment but occur following incomplete arousals from slow-wave
sleep. All Non-REM parasomnias share a common pathophysiology that
relies on the breakdown of the boundaries between the wakefulness
and sleep regulatory systems during slow-wave sleep. Compared with
Rapid Eye Movement (REM) Sleep Behavior Disorder (RBD) which occurs
during REM sleep and can be related to dream enactment.
[0256] Dementia with Lewy bodies (DLB) is a progressive
neurocognitive illness characterized pathologically by the presence
of diffuse clusters comprised of alpha synuclein and other proteins
that aggregate in the brain and disrupt cognitive function. DLB is
considered to be the second most prevalent cause of degenerative
dementia in the elderly population, accounting for up to 15%-25% of
dementia presentations and 15%-20% of all autopsy confirmed
dementias in old age. Between 50% and 80% of subjects with
Parkinson's disease may experience dementia over the course of
their illness. While few studies of the exact prevalence of DLB
have been published, the Lewy Body Dementia Association estimates
that 1.1 million individuals are affected by DLB in the U.S. alone.
While cognitive dysfunction manifested as deficits and fluctuation
in attention is a core component of DLB, subjects also exhibit
prominent behavioral disturbances early in the disease, including
RBD behaviors. RBD affects between 50% and 80% of patients with DLB
and is characterized by the presence of abnormal behaviors and
vocalizations during the phase of sleep associated with REM and
during sleep phase transitions. While individuals are normally
paralyzed during REM sleep, individuals with RBD lack muscle atonia
during otherwise intact REM sleep. Hence, patients exhibit violent
behaviors that mirror their dream content, including screaming and
running during sleep, and kicking, punching, or strangling their
bed partners. Patients have limited recall of these behaviors,
which are often observed only by their bed partners. While the
pathophysiology of RBD is poorly understood, the condition has been
linked with visual hallucinations in Lewy body diseases. The
presence of RBD has been associated with an increased risk of
hallucinations and delusions in Parkinson's disease. Moreover,
dream content during sleep-onset REM periods can resemble the
content of daytime hallucinations, with patients reacting to the
content of dreams that often involve themes of being chased or
attacked. In addition, it has been shown that visual hallucinations
can coincide with periods of REM. Thus, a drug that reduces visual
hallucinations may also have the potential to reduce REM sleep
behaviors. Despite the high prevalence of RBD and its dramatic
impact on the quality of life of patients and their families, no
medications are currently approved for its treatment. Indeed, there
have been few randomized controlled trials to evaluate the efficacy
and safety of drugs to treat RBD. Clonazepam, a long-acting
benzodiazepine, is commonly used off-label to treat patients with
RBD. The drug is associated with concerning side effects in elderly
patients, including confusion, daytime sedation, and increased risk
of falls. Moreover, the long-term use of benzodiazepines has been
shown to be associated with cognitive impairment, a particularly
concerning side effect in patients with dementia. There remains a
significant unmet need for safe and effective new therapies for
patients with RBD.
[0257] In addition to the foregoing beneficial uses for the
modulators of 5-HT.sub.2A receptor activity disclosed herein, the
compounds disclosed herein are believed to be useful in the
treatment of REM sleep behavior disorder, and in the amelioration
of symptoms thereof.
[0258] Rapid eye movement (REM) sleep behavior disorder is a sleep
disorder wherein subjects physically act out vivid, often
unpleasant dreams with vocal sounds and sudden, often violent arm
and leg movements during REM sleep, sometimes called dream-enacting
behavior.
[0259] Subjects normally do not move during REM sleep, a normal
stage of sleep that occurs many times during the night. About 20%
of a subject's sleep is spent in REM sleep, the usual time for
dreaming, which occurs primarily during the second half of the
night. The onset of REM sleep behavior disorder is often sudden,
and episodes may occur occasionally or several times a night. The
disorder can get worse with time.
[0260] REM sleep behavior disorder often may be associated with
other neurological conditions, such as Lewy body dementia (which
includes dementia with Lewy bodies, Parkinson's disease dementia),
Parkinson's disease or multiple system atrophy and Alzheimer's
disease.

1-[3-(4-bromo-2-methyl-2H-pyrazol-3-yl)-4-methoxy-phenyl]-3-(2,4-difluoro-
-phenyl)-urea is about 10 mg. In some embodiments, the
therapeutically effective amount of
1-[3-(4-bromo-2-methyl-2H-pyrazol-3-yl)-4-methoxy-phenyl]-3-(2,4-difluoro-
-phenyl)-urea is about 20 mg. In some embodiments, the
therapeutically effective amount of
1-[3-(4-bromo-2-methyl-2H-pyrazol-3-yl)-4-methoxy-phenyl]-3-(2,4-difluoro-
-phenyl)-urea is about 40 mg. In some embodiments, the
therapeutically effective amount of
1-[3-(4-bromo-2-methyl-2H-pyrazol-3-yl)-4-methoxy-phenyl]-3-(2,4-difluoro-
-phenyl)-urea is about 80 mg. In some embodiments, the
therapeutically effective amount of
1-[3-(4-bromo-2-methyl-2H-pyrazol-3-yl)-4-methoxy-phenyl]-3-(2,4-difluoro-
-phenyl)-urea is about 160 mg.
[0305] Conventional excipients, such as binding agents, fillers,
acceptable wetting agents, tableting lubricants, and disintegrants
may be used in tablets and capsules for oral administration. Liquid
preparations for oral administration may be in the form of
solutions, emulsions, aqueous or oily suspensions, and syrups.
Alternatively, the oral preparations may be in the form of dry
powder that can be reconstituted with water or another suitable
liquid vehicle before use. Additional additives such as suspending
or emulsifying agents, non-aqueous vehicles (including edible
oils), preservatives, and flavorings and colorants may be added to
the liquid preparations. Parenteral dosage forms may be prepared by
dissolving the compound of the invention in a suitable liquid
vehicle and filter sterilizing the solution before filling and
sealing an appropriate vial or ampoule. These are just a few
examples of the many appropriate methods well known in the art for
preparing dosage forms.
[0306] A compound of the present invention can be formulated into
pharmaceutical compositions using techniques well known to those in
the art. Suitable pharmaceutically-acceptable carriers, outside
those mentioned herein, are known in the art; for example, see
Remington, The Science and Practice of Pharmacy, 20th Edition,
2000, Lippincott Williams & Wilkins, (Editors: Gennaro, A. R.,
et al.).
[0307] While it is possible that, for use in the prophylaxis or
treatment, a compound of the invention may, in an alternative use,
be administered as a raw or pure chemical, it is preferable to
present the compound or active ingredient as a pharmaceutical
formulation or composition further comprising a pharmaceutically
acceptable carrier.
[0308] The invention thus further provides pharmaceutical
formulations comprising a compound of the invention or a
pharmaceutically acceptable salt or derivative thereof together
with one or more pharmaceutically acceptable carriers thereof
and/or prophylactic ingredients. The carrier(s) must be
"acceptable" in the sense of being compatible with the other
ingredients of the formulation and not overly deleterious to the
recipient thereof.
[0309] Pharmaceutical formulations include those suitable for oral,
rectal, nasal, topical (including buccal and sub-lingual), vaginal
or parenteral (including intramuscular, sub-cutaneous and
intravenous) administration or in a form suitable for
administration by inhalation, insulation or by a transdermal patch.
Transdermal patches dispense a drug at a controlled rate by
presenting the drug for absorption in an efficient manner with a
minimum of degradation of the drug. Typically, transdermal patches
comprise an impermeable backing layer, a single pressure sensitive
adhesive and a removable protective layer with a release liner. One
of ordinary skill in the art will understand and appreciate the
techniques appropriate for manufacturing a desired efficacious
transdermal patch based upon the needs of the artisan.
[0310] The compounds of the invention, together with a conventional
adjuvant, carrier, or diluent, may thus be placed into the form of
pharmaceutical formulations and unit dosages thereof, and in such
form may be employed as solids, such as tablets or filled capsules,
or liquids such as solutions, suspensions, emulsions, elixirs, gels
or capsules filled with the same, all for oral use; in the form of
suppositories for rectal administration; or in the form of sterile
injectable solutions for parenteral (including subcutaneous) use.
Such pharmaceutical compositions and unit dosage forms thereof may
comprise conventional ingredients in conventional proportions, with
or without additional active compounds or principles, and such unit
dosage forms may contain any suitable effective amount of the
active ingredient commensurate with the intended daily dosage range
to be employed.
[0311] For oral administration, the pharmaceutical composition may
be in the form of, for example, a tablet, capsule, suspension or
liquid. The pharmaceutical composition is preferably made in the
form of a dosage unit containing a particular amount of the active
ingredient. Examples of such dosage units are capsules, tablets,
powders, granules or a suspension, with conventional additives such
as lactose, mannitol, corn starch or potato starch; with binders
such as crystalline cellulose, cellulose derivatives, acacia, corn
starch or gelatins; with disintegrators such as corn starch, potato
starch or sodium carboxymethyl-cellulose; and with lubricants such
as talc or magnesium stearate. The active ingredient may also be
administered by injection as a composition wherein, for example,
saline, dextrose or water may be used as a suitable
pharmaceutically acceptable carrier.
[0312] Compounds of the present invention or a solvate or
physiologically functional derivative thereof can be used as active
ingredients in pharmaceutical compositions, specifically as
5-HT.sub.2A receptor modulators. By the term "active ingredient" is
defined in the context of a "pharmaceutical composition" and shall
mean a component of a pharmaceutical composition that provides the
primary pharmacological effect, as opposed to an "inactive
ingredient" which would generally be recognized as providing no
pharmaceutical benefit.
[0313] The dose when using the compounds of the present invention
can vary within wide limits, and as is customary and is known to
the physician, it is to be tailored to the individual conditions in
each individual case. It depends, for example, on the nature and
severity of the illness to be treated, on the condition of the
patient, on the compound employed or on whether an acute or chronic
disease state is treated or prophylaxis is conducted or on whether
further active compounds are administered in addition to the
compounds of the present invention. Representative doses of the
present invention include, but are not limited to, about 0.001 mg
to about 5000 mg, about 0.001 mg to about 2500 mg, about 0.001 mg
to about 1000 mg, 0.001 mg to about 500 mg, 0.001 mg to about 250
mg, about 0.001 mg to 100 mg, about 0.001 mg to about 50 mg, and
about 0.001 mg to about 25 mg. Representative doses of the present
invention include, but are not limited to, about 0.0001 to about
1,000 mg, about 10 to about 160 mg, about 10 mg, about 20 mg, about
40 mg, about 80 mg or about 160 mg. Multiple doses may be
administered during the day, especially when relatively large
amounts are deemed to be needed, for example 2, 3 or 4, doses. In
some embodiments, the dose is administered once daily in the
morning, twice daily, or once daily about 1 hour prior to the
subject's bedtime. Depending on the individual and as deemed
appropriate from the patient's physician or care-giver it may be
necessary to deviate upward or downward from the doses described
herein.
[0314] The amount of active ingredient, or an active salt or
derivative thereof, required for use in treatment will vary not
only with the particular salt selected but also with the route of
administration, the nature of the condition being treated and the
age and condition of the patient and will ultimately be at the
discretion of the attendant physician or clinician. In general, one
skilled in the art understands how to extrapolate in vivo data
obtained in a model system, typically an animal model, to another,
such as a human. In some circumstances, these extrapolations may
merely be based on the weight of the animal model in comparison to
another, such as a mammal, preferably a human; however, more often,
these extrapolations are not simply based on weights, but rather
incorporate a variety of factors. Representative factors include
the type, age, weight, sex, diet and medical condition of the
patient, the severity of the disease, the route of administration,
pharmacological considerations such as the activity, efficacy,
pharmacokinetic and toxicology profiles of the particular compound
employed, whether a drug delivery system is utilized, on whether an
acute or chronic disease state is being treated or prophylaxis is
conducted or on whether further active compounds are administered
in addition to the compounds of the present invention and as part
of a drug combination. The dosage regimen for treating a disease
condition with the compounds and/or compositions of this invention
is selected in accordance with a variety of factors as cited above.
Thus, the actual dosage regimen employed may vary widely and
therefore may deviate from a preferred dosage regimen and one
skilled in the art will recognize that dosage and dosage regimen
outside these typical ranges can be tested and, where appropriate,
may be used in the methods of this invention.
[0315] The desired dose may conveniently be presented in a single
dose or as divided doses administered at appropriate intervals, for
example, as two, three, four or more sub-doses per day. The
sub-dose itself may be further divided, e.g., into a number of
discrete loosely spaced administrations. The daily dose can be
divided, especially when relatively large amounts are administered
as deemed appropriate, into several, for example 2, 3 or 4, part
administrations. If appropriate, depending on individual behavior,
it may be necessary to deviate upward or downward from the daily
dose indicated.
[0316] The compounds of the present invention can be administrated
in a wide variety of oral and parenteral dosage forms. It will be
obvious to those skilled in the art that the following dosage forms
may comprise, as the active component, either a compound of the
invention or a pharmaceutically acceptable salt of a compound of
the invention.
[0317] For preparing pharmaceutical compositions from the compounds
of the present invention, the selection of a suitable
pharmaceutically acceptable carrier can be either solid, liquid or
a mixture of both. Solid form preparations include powders,
tablets, pills, capsules, cachets, suppositories, and dispersible
granules. A solid carrier can be one or more substances which may
also act as diluents, flavouring agents, solubilizers, lubricants,
suspending agents, binders, preservatives, tablet disintegrating
agents, or an encapsulating material.
[0318] In powders, the carrier is a finely divided solid which is
in a mixture with the finely divided active component.
[0319] In tablets, the active component is mixed with the carrier
having the necessary binding capacity in suitable proportions and
compacted to the desired shape and size.
[0320] The powders and tablets may contain varying percentage
amounts of the active compound. A representative amount in a powder
or tablet may contain from 0.5 to about 90 percent of the active
compound; however, an artisan would know when amounts outside of
this range are necessary. Suitable carriers for powders and tablets
are magnesium carbonate, magnesium stearate, talc, sugar, lactose,
pectin, dextrin, starch, gelatin, tragacanth, methylcellulose,
sodium carboxymethylcellulose, a low melting wax, cocoa butter, and
the like. The term "preparation" is intended to include the
formulation of the active compound with encapsulating material as
carrier, providing a capsule in which the active component, with or
without carriers, is surrounded by a carrier, which is thus in
association with it. Similarly, cachets and lozenges are included.
Tablets, powders, capsules, pills, cachets, and lozenges can be
used as solid forms suitable for oral administration.
[0321] For preparing suppositories, a low melting wax, such as an
admixture of fatty acid glycerides or cocoa butter, is first melted
and the active component is dispersed homogeneously therein, as by
stirring. The molten homogenous mixture is then poured into
convenient sized molds, allowed to cool, and thereby to
solidify.
[0322] Formulations suitable for vaginal administration may be
presented as pessaries, tampons, creams, gels, pastes, foams or
sprays containing in addition to the active ingredient such
carriers as are known in the art to be appropriate.
[0323] Liquid form preparations include solutions, suspensions, and
emulsions, for example, water or water-propylene glycol solutions.
For example, parenteral injection liquid preparations can be
formulated as solutions in aqueous polyethylene glycol solution.
Injectable preparations, for example, sterile injectable aqueous or
oleaginous suspensions may be formulated according to the known art
using suitable dispersing or wetting agents and suspending agents.
The sterile injectable preparation may also be a sterile injectable
solution or suspension in a nontoxic parenterally acceptable
diluent or solvent, for example, as a solution in 1,3-butanediol.
Among the acceptable vehicles and solvents that may be employed are
water, Ringer's solution, and isotonic sodium chloride solution. In
addition, sterile, fixed oils are conventionally employed as a
solvent or suspending medium. For this purpose any bland fixed oil
may be employed including synthetic mono- or diglycerides. In
addition, fatty acids such as oleic acid find use in the
preparation of injectables.
[0324] The compounds according to the present invention may thus be
formulated for parenteral administration (e.g. by injection, for
example bolus injection or continuous infusion) and may be
presented in unit dose form in ampoules, pre-filled syringes, small
volume infusion or in multi-dose containers with an added
preservative. The pharmaceutical compositions may take such forms
as suspensions, solutions, or emulsions in oily or aqueous
vehicles, and may contain formulatory agents such as suspending,
stabilizing and/or dispersing agents. Alternatively, the active
ingredient may be in powder form, obtained by aseptic isolation of
sterile solid or by lyophilization from solution, for constitution
with a suitable vehicle, e.g. sterile, pyrogen-free water, before
use.
[0325] Aqueous formulations suitable for oral use can be prepared
by dissolving or suspending the active component in water and
adding suitable colorants, flavors, stabilizing and thickening
agents, as desired.
[0326] Aqueous suspensions suitable for oral use can be made by
dispersing the finely divided active component in water with
viscous material, such as natural or synthetic gums, resins,
methylcellulose, sodium carboxymethylcellulose, or other well-known
suspending agents.
[0327] Also included are solid form preparations which are intended
to be converted, shortly before use, to liquid form preparations
for oral administration. Such liquid forms include solutions,
suspensions, and emulsions. These preparations may contain, in
addition to the active component, colorants, flavors, stabilizers,
buffers, artificial and natural sweeteners, dispersants,
thickeners, solubilizing agents, and the like.
[0328] For topical administration to the epidermis the compounds
according to the invention may be formulated as ointments, creams
or lotions, or as a transdermal patch.
[0329] Ointments and creams may, for example, be formulated with an
aqueous or oily base with the addition of suitable thickening
and/or gelling agents. Lotions may be formulated with an aqueous or
oily base and will in general also contain one or more emulsifying
agents, stabilizing agents, dispersing agents, suspending agents,
thickening agents, or coloring agents.
[0330] Formulations suitable for topical administration in the
mouth include lozenges comprising the active agent in a flavored
base, usually sucrose and acacia or tragacanth; pastilles
comprising the active ingredient in an inert base such as gelatin
and glycerin or sucrose and acacia; and mouthwashes comprising the
active ingredient in a suitable liquid carrier.
[0331] Solutions or suspensions are applied directly to the nasal
cavity by conventional means, for example with a dropper, pipette
or spray. The formulations may be provided in single or multi-dose
form. In the latter case of a dropper or pipette, this may be
achieved by the patient administering an appropriate, predetermined
volume of the solution or suspension. In the case of a spray, this
may be achieved, for example, by means of a metering atomizing
spray pump.
[0332] Administration to the respiratory tract may also be achieved
by means of an aerosol formulation in which the active ingredient
is provided in a pressurized pack with a suitable propellant. If
the compounds of the present invention or pharmaceutical
compositions comprising them are administered as aerosols, for
example as nasal aerosols or by inhalation, this can be carried
out, for example, using a spray, a nebulizer, a pump nebulizer, an
inhalation apparatus, a metered inhaler or a dry powder inhaler.
Pharmaceutical forms for administration of the compounds of the
present invention as an aerosol can be prepared by processes
well-known to a person skilled in the art. For their preparation,
for example, solutions or dispersions of the compounds of the
present invention in water, water/alcohol mixtures or suitable
saline solutions can be employed using customary additives, for
example benzyl alcohol or other suitable preservatives, absorption
enhancers for increasing the bioavailability, solubilizers,
dispersants and others, and, if appropriate, customary propellants,
for example include carbon dioxide, CFC's, such as,
dichlorodifluoromethane, trichlorofluoromethane, or
dichlorotetrafluoroethane; and the like. The aerosol may
conveniently also contain a surfactant such as lecithin. The dose
of drug may be controlled by provision of a metered valve.
[0333] In formulations intended for administration to the
respiratory tract, including intranasal formulations, the compound
will generally have a small particle size for example of the order
of 10 microns or less. Such a particle size may be obtained by
means known in the art, for example by micronization. When desired,
formulations adapted to give sustained release of the active
ingredient may be employed.
[0334] Alternatively the active ingredients may be provided in the
form of a dry powder, for example, a powder mix of the compound in
a suitable powder base such as lactose, starch, starch derivatives
such as hydroxypropylmethyl cellulose and polyvinylpyrrolidone
(PVP). Conveniently the powder carrier will form a gel in the nasal
cavity. The powder composition may be presented in unit dose form
for example in capsules or cartridges of, e.g., gelatin, or blister
packs from which the powder may be administered by means of an
inhaler:
[0335] The pharmaceutical preparations are preferably in unit
dosage forms. In such form, the preparation is subdivided into unit
doses containing appropriate quantities of the active component.
The unit dosage form can be a packaged preparation, the package
containing discrete quantities of preparation, such as packeted
tablets, capsules, and powders in vials or ampoules. Also, the unit
dosage form can be a capsule, tablet, cachet, or lozenge itself, or
it can be the appropriate number of any of these in packaged
form.
[0336] Tablets or capsules for oral administration and liquids for
intravenous administration are preferred compositions.
[0337] The compounds according to the invention may optionally
exist as pharmaceutically acceptable salts including
pharmaceutically acceptable acid addition salts prepared from
pharmaceutically acceptable non-toxic acids including inorganic and
organic acids. Representative acids include, but are not limited
to, acetic, benzenesulfonic, benzoic, camphorsulfonic, citric,
ethanesulfonic, dichloroacetic, formic, fumaric, gluconic,
glutamic, hippuric, hydrobromic, hydrochloric, isethionic, lactic,
maleic, malic, mandelic, methanesulfonic, mucic, nitric, oxalic,
pamoic, pantothenic, phosphoric, succinic, sulfuric, tartaric,
oxalic, p-toluenesulfonic and the like, such as those
pharmaceutically acceptable salts listed in Journal of
Pharmaceutical Science, 66, 2 (1977); incorporated herein by
reference in its entirety.
[0338] The acid addition salts may be obtained as the direct
products of compound synthesis. In the alternative, the free base
may be dissolved in a suitable solvent containing the appropriate
acid, and the salt isolated by evaporating the solvent or otherwise
separating the salt and solvent. The compounds of this invention
may form solvates with standard low molecular weight solvents using
methods known to the skilled artisan.
[0339] Compounds of the present invention can be converted to
"pro-drugs." The term "pro-drugs" refers to compounds that have
been modified with specific chemical groups known in the art and
when administered into an individual these groups undergo
biotransformation to give the parent compound. Pro-drugs can thus
be viewed as compounds of the invention containing one or more
specialized non-toxic protective groups used in a transient manner
to alter or to eliminate a property of the compound. In one general
aspect, the "pro-drug" approach is utilized to facilitate oral
absorption. A thorough discussion is provided in T. Higuchi and V.
Stella, "Pro-drugs as Novel Delivery Systems," Vol. 14 of the A. C.
S. Symposium Series; and in Bioreversible Carriers in Drug Design,
ed. Edward B. Roche, American Pharmaceutical Association and
Pergamon Press, 1987, both of which are hereby incorporated by
reference in their entirety.
[0340] Some embodiments of the present invention include a method
of producing a pharmaceutical composition for "combination-therapy"
comprising admixing at least one compound according to any of the
compound embodiments disclosed herein, together with at least one
known pharmaceutical agent as described herein and a
pharmaceutically acceptable carrier.
[0341] It is noted that when the 5-HT.sub.2A receptor modulators
are utilized as active ingredients in a pharmaceutical composition,
these are not intended for use only in humans, but in other
non-human mammals as well. Indeed, recent advances in the area of
animal healthcare mandate that consideration be given for the use
of active agents, such as 5-HT.sub.2A receptor modulators, for the
treatment of a 5-HT.sub.2A mediated disease or disorder in domestic
animals (e.g., cats and dogs) and in other domestic animals (e.g.,
such as cows, chickens, fish, etc.). Those of ordinary skill in the
art are readily credited with understanding the utility of such
compounds in such settings.
[0342] One aspect of the present invention encompasses methods for
the prophylaxis and/or treatment of REM sleep behavior disorder,
idiopathic REM sleep behavior disorder, or a combination thereof,
in an individual comprising administering to said individual in

therapeutically effective amount of
1-[3-(4-bromo-2-methyl-2H-pyrazol-3-yl)-4-methoxy-phenyl]-3-(2,4-difluoro-
-phenyl)-urea is about 80 mg. In some embodiments, the
therapeutically effective amount of
1-[3-(4-bromo-2-methyl-2H-pyrazol-3-yl)-4-methoxy-phenyl]-3-(2,4-difluoro-
-phenyl)-urea is about 160 mg.

subjects: Planned 1. Nelotanserin 80 mg: 26 subjects 2. Placebo: 26
subjects Number of Study Approximately 15-20 Centers Planned Study
Design This is a multi-center, double-blind, randomized,
placebo-controlled study in DLB subjects with RBD. Subjects will
participate in a whole-night video- PSG study at a specified sleep
lab during the single-blind placebo run-in period and at the end of
the double-blind treatment. To allow subjects to acclimate to the
sleep lab environment, subjects will spend a minimum of two
(preferably consecutive) nights at the sleep lab. During this
study, the subject must have at least one qualifying night of REM
sleep (a qualifying night of REM sleep is defined as a night with
REM sleep duration of .gtoreq.10 minutes). ActiGraph activity
monitor will be used to assess physical activity during sleep
during the study. The primary objective of the study will be to
evaluate the efficacy and safety of nelotanserin as compared to
placebo in DLB subjects with a concurrent diagnosis of RBD who have
frequent RBD behaviors. Following an initial screening, eligible
subjects will enter a single-blind placebo run-in period of up to 3
weeks in duration. At the end of this period, all subjects who
continue to meet the eligibility criteria will enter a four- week
double-blind treatment period. Each subject will be randomized 1:1
to either nelotanserin 80 mg or matching placebo. For subjects
assigned to nelotanserin 80 mg, the dose will be titrated up to the
80 mg dose strength in a blinded fashion after initial 5 days of
treatment with 40 mg nelotanserin. Following the final visit, all
subjects who either have completed the study will be eligible to
participate in an open-label extension period with nelotanserin.
The study design is outlined in FIG. 1. Duration of Treatment Study
participation will last approximately 7-11 weeks: 0-28 days for
screening, an up to 3 week single-blind placebo run-in period to
evaluate baseline status, and a four-week randomized double-blind
treatment period. Following the final visit, eligible subjects will
have the option to participate in an open-label extension period
with nelotanserin. Criteria for Evaluation Primary Efficacy
Measure: To assess the effects of nelotanserin versus placebo on
frequency per 10 minutes of REM sleep of characteristic RBD
behaviors (both simple or major movements and vocalizations) based
on video/audio assessment conducted at a sleep lab. The primary
endpoint is defined as the change in frequency per 10 minutes of
REM sleep of RBD behaviors from baseline (the whole-night sleep
study after 2 weeks of placebo run-in) to the end of treatment (the
whole-night sleep study at the end of treatment). Secondary
Efficacy Measures: To assess the effects of nelotanserin versus
placebo on change in the proportion of severe RBD behaviors
measured by video/audio assessment conducted at a sleep lab; To
assess the effects of nelotanserin versus placebo on change in a
composite score based on both nightly severity and nightly
frequency of RBD behaviors measured by video/audio assessment
conducted at a sleep lab; To assess the effects of nelotanserin
versus placebo on change in the number of nights with injurious
behaviors to subject or bed partner as recorded on study diary
completed by subject and/or bed partner/caregiver; To assess the
effects of nelotanserin versus placebo on change in the number of
nights with dramatic dreams per week as recorded on study diary
completed by subject and/or bed partner/caregiver; To assess the
effects of nelotanserin versus placebo on change in subjective
sleep quality as measured by Scales for Outcomes in Parkinson's
disease (SCOPA) - Sleep; To assess the effects of nelotanserin
versus placebo on change in quality of bed partner sleep as
measured by a visual analog scale (VAS) completed by the bed
partner; To assess the effects of nelotanserin versus placebo on
Clinicians' Global Impression of Change (CGIC) related to RBD
behaviors; To assess the effects of nelotanserin versus placebo on
change in objective sleep parameters obtained from PSG at a sleep
lab; To assess the effects of nelotanserin versus placebo on change
in physical activity during sleep as measured by ActiGraph activity
monitor; To assess the effects of nelotanserin versus placebo on
change in duration of VHs as recorded on study diary completed by
subject and/or bed partner/caregiver; To assess the effects of
nelotanserin versus placebo on change in duration of auditory
hallucinations as recorded on study diary completed by subject
and/or bed partner/caregiver; Safety Evaluation: Safety will be
evaluated based on adverse events (AEs), physical examinations,
vital signs, electrocardiograms (ECGs), and routine clinical
laboratory assessments. Extrapyramidal signs are assessed with the
motor subsection of the Unified Parkinson's Disease Rating Scale
(UPDRS, Parts II and III). Cognitive functioning is assessed with
the Montreal Cognitive Assessment (MoCA) scale and the Mini-Mental
State Examination (MMSE). Pharmacokinetic Evaluation: A blood
sample for determination of plasma nelotanserin and M1 metabolite
concentration will be collected after the last dose of study
treatment. Statistical Methods Sample Size: A sample size of 52
subjects (26 subjects per treatment arm) would provide power of
0.80 to detect a 0.8 unit treatment group difference in the change
from baseline to end of treatment in the nightly frequency of RBD
behaviors (both simple and major movements and vocalizations)
measured by video assessment conducted at a sleep lab, assuming SD
of 1 unit using an analysis of covariance (ANCOVA) model with a
single two- level between-groups fixed effect and two covariates
and a significance level for Type-I error (.alpha.) of 0.05.
Efficacy: For the change in frequency of RBD behaviors observed in
the sleep lab during the single-blind placebo run-in period (visit
3 [V3]) and at the end of treatment, treatment arm comparisons
between nelotanserin 80 mg and placebo in the change in frequency
of RBD behaviors per 10 minutes of REM sleep from V3 to the end of
treatment will be analysed using an ANCOVA model that includes
treatment as a fixed effect and both the frequency of RBD behaviors
at V3 and background treatment of melatonin/clonazepam as
covariates. For the change in severity of RBD behaviors observed in
the sleep lab at V3 and at the end of treatment, treatment arm
comparisons between nelotanserin 80 mg and placebo in the change in
proportion of RBD behaviors classified as severe at V3 and at the
end of treatment will be analysed using a generalized estimating
equation (GEE) that includes treatment arm, visit, and the
interaction of treatment arm and visit as fixed effects and
background treatment of melatonin/clonazepam as a covariate.
Treatment comparisons for end of treatment values of each
continuous secondary efficacy endpoint that will be assessed at
baseline and the final visit only will be analysed using an ANCOVA
model that includes treatment as a fixed effect and both baseline
value of the efficacy endpoint and
background treatment of melatonin/clonazepam as covariates.
Treatment comparisons for end of treatment values of each
continuous secondary efficacy endpoint that will be assessed at the
final visit only (ie, CGIC) will be analysed using an ANCOVA model
that includes treatment as a fixed effect and background treatment
of melatonin/clonazepam as a covariate. For continuous secondary
efficacy endpoints that will be assessed daily over the course of
the study, daily averages of the outcomes will be calculated for
each week of the trial. Treatment comparisons in the change in
average outcomes scores from the baseline week (over the last 7
days of placebo run- in) to the final week (over the last 7 days of
treatment) will be analysed using an ANCOVA model that includes
treatment as a fixed effect and background treatment of
melatonin/clonazepam as a covariate. Treatment comparisons for
categorical secondary efficacy endpoints between groups will be
analysed using Fisher's exact test. Safety: Safety will be assessed
by summarizing and analyzing AEs, laboratory analytes, vital signs,
physical examination, and ECG parameters. For treatment comparisons
of change in UPDRS II, UPDRS III, and UPDRS II and III composite
scores, as well as change in MMSE and MoCA scores, statistical
significance of treatment group differences in end of treatment
values will be estimated using univariate ANCOVA models that
include treatment arm as a fixed effect and both baseline value of
the score and background treatment of melatonin/clonazepam as
covariates. Pharmacokinetics/pharmacodynamics (PK/PD): Plasma
nelotanserin and M1 metabolite concentrations will be listed and
summarized. Exploratory PK/PD analysis will include a plot of
nelotanserin and M1 plasma concentrations versus the change in
nightly frequency of RBD behaviors.
[0371] Rapid Eye Movement (REM) Sleep Behavior Disorder (RBD) in
Dementia with Lewy Bodies (DLB): Dementia with Lewy bodies (DLB) is
a progressive neurocognitive illness characterized pathologically
by the presence of diffuse clusters comprised of alpha synuclein
and other proteins that aggregate in the brain and disrupt
cognitive function. DLB is considered to be the second most
prevalent cause of degenerative dementia in the elderly population
(McKeith 2004), accounting for up to 15%-25% of dementia
presentations (McKeith 2000) and 15%-20% of all autopsy confirmed
dementias in old age (Mosimann 2003). Between 50% and 80% of
subjects with Parkinson's disease may experience dementia over the
course of their illness (Alzheimer's Association 2015). While few
studies of the exact prevalence of DLB have been published, the
Lewy Body Dementia Association estimates that 1.1 million
individuals are affected by DLB in the U.S. alone.
[0372] While cognitive dysfunction, manifested as deficits and
fluctuation in attention is a core component of DLB, subjects also
exhibit prominent behavioral disturbances early in the disease,
including rapid eye movement (REM) sleep behavior disorder (RBD)
behaviors. RBD affects between 50% and 80% of patients with DLB
(Boeve 2007) and is characterized by the presence of abnormal
behaviors and vocalizations during the phase of sleep associated
with REM and during sleep phase transitions. While individuals are
normally paralyzed during REM sleep, individuals with RBD lack
muscle atonia during otherwise intact REM sleep. Hence, patients
exhibit violent behaviors that mirror their dream content,
including screaming and running during sleep, and kicking,
punching, or strangling their bed partners. Patients have limited
recall of these behaviors, which are often observed only by their
bed partners.
[0373] While the pathophysiology of RBD is poorly understood, the
condition has been linked with visual hallucinations (VHs) in Lewy
body diseases. The presence of RBD has been associated with an
increased risk of hallucinations and delusions in Parkinson's
disease (Pacchetti 2005). Moreover, dream content during
sleep-onset REM periods can resemble the content of daytime
hallucinations (Pfeiffer 2013), with patients reacting to the
content of dreams that often involve themes of being chased or
attacked (Pfeiffer 2013). In addition, it has been shown that VHs
can coincide with periods of REM (Pfeiffer 2013). Thus, a drug that
reduces VHs may also have the potential to reduce REM sleep
behaviors.
[0374] Despite the high prevalence of RBD and its dramatic impact
on the quality of life of patients and their families, no
medications are currently approved for its treatment. Indeed, there
have been few randomized controlled trials to evaluate the efficacy
and safety of drugs to treat RBD. Clonazepam, a long-acting
benzodiazepine, is commonly used off-label to treat patients with
RBD. The drug is associated with concerning side effects in elderly
patients, including confusion, daytime sedation, and increased risk
of falls (Anderson 2009). Moreover, the long-term use of
benzodiazepines has been shown to be associated with cognitive
impairment (Barker 2004), a particularly concerning side effect in
patients with dementia. There remains a significant unmet need for
safe and effective new therapies for patients with RBD.
[0375] Nelotanserin: Nelotanserin (RVT-102), previously known as
APD-125, is a potent and selective 5HT2a receptor inverse agonist,
and is currently being developed as an oral treatment for REM sleep
behavior disorder in patients with DLB. Originally being developed
for primary insomnia, seven clinical studies have been completed to
date that included five Phase 1 and two Phase 2 studies, and 792
individuals have been exposed to nelotanserin over the dose range
of 20 to 160 mg and up to 14 days. In the studies completed to
date, nelotanserin has exhibited a favorable safety and
tolerability profile.
[0376] Indication Rationale: Evaluation of nelotanserin for the
treatment of RBD behaviors in patients with DLB is warranted by the
following: (1) evidence in Phase 1 and Phase 2 studies that
nelotanserin increases slow wave sleep and improves sleep
maintenance and consolidation; (2) evidence that nelotanserin
reduces the number of sleep phase transitions, which represent
critical junctures at which RBD patients are particularly at risk
of sleep behaviors; (3) overlap in the content of VHs and dreams
experienced during RBD episodes, suggesting that a drug that
reduces VHs may also impact dream content in a way that reduces the
manifestation of violent behaviors; (4) evidence that other agents
that block 5-HT2a neurotransmission, for example pimavanserin, may
improve sleep quality in patients with Parkinson's disease
(Cummings 2014; Friedman 2013), an illness that shares similar Lewy
body pathology and clinical manifestations with DLB; and, (5) an
acceptable safety and tolerability profile of nelotanserin based on
previous clinical studies to date in the proposed dose range.
[0377] Dose Rationale: Based on the nonclinical studies conducted
to date and the available clinical data, the 80 mg dose is
considered a dose with sufficient safety margin to be evaluated in
patients with DLB who experience RBD behaviors.

Safety To assess the safety of nelotanserin in DLB Safety will be
assessed by analyzing adverse subjects with RBD behaviors events
(AEs), laboratory values, vital signs, and physical examinations.
Extrapyramidal signs are assessed with the motor subsection of the
Unified Parkinson's Disease Rating Scale (UPDRS, Parts II and III).
Cognitive functioning is assessed with the Montreal Cognitive
Assessment (MoCA) scale and the Mini-Mental State Examination
(MMSE). Pharmacokinetic To assess the steady-state plasma exposure

metabolite, and concentration on Day 29. relationship to primary
endpoint Analysis of the relationship between plasma nelotanserin
and M1 concentrations and the change in nightly frequency of RBD
behaviors.
[0378] Overall Design: This is a multi-center, double-blind,
randomized, placebo-controlled study in DLB subjects with RBD.
Subjects will participate in a whole-night video-polysomnographic
(video-PSG) study at a specified sleep lab during the single-blind
placebo run-in period and at the end of the double-blind treatment.
To allow subjects to acclimate to the sleep lab environment,
subjects will spend a minimum of two (preferably consecutive)
nights at the sleep lab. During this study, the subject must have
at least one qualifying night of REM sleep (a qualifying night of
REM sleep is defined as a night with REM sleep duration of
.gtoreq.10 minutes). ActiGraph activity monitors worn on both
wrists will be used to assess physical activity during sleep during
the study.
[0379] The primary objective of the study will be to evaluate the
efficacy and safety of nelotanserin as compared to placebo in DLB
subjects with a concurrent diagnosis of RBD who have frequent RBD
behaviors.
[0380] Following an initial screening, eligible subjects will enter
a single-blind placebo run-in period of up to 3 weeks in duration.
At the end of this period, all subjects who continue to meet the
eligibility criteria will enter a four-week double-blind treatment
period. Each subject will be randomized 1:1 to either nelotanserin
80 mg or matching placebo. For subjects assigned to nelotanserin 80
mg, the dose will be titrated up to the 80 mg dose strength in a
blinded fashion after initial 5 days of treatment with 40 mg
nelotanserin.
[0381] Following the final visit, all subjects who have completed
the study will be eligible to participate in an open-label
extension period with nelotanserin. The study design is outlined in
FIG. 1.
[0382] Subject Population:
[0383] The study will randomize approximately 52 subjects with DLB
who experience frequent RBD behaviors prior to screening and have 4
or more RBD episodes (one or more of which must include complex RBD

menses at any time during the preceding 24 consecutive months).
[0385] Exclusion Criteria: Subjects' sleep behavioral symptoms are
secondary to or better accounted for by another medical condition
(eg, untreated or sub-optimally treated obstructive sleep apnea
[OSA]), psychiatric disorder (eg, other non-REM parasomnias,
multiple system atrophy), or substance abuse (eg, alcoholism);
Subjects have a current diagnosis of significant psychotic
disorders including, but not limited to, schizophrenia or bipolar
disorder; Any significant change in the subject's environment
within the past 4 weeks; Subjects with a history of significant
cerebrovascular events; Subjects with a current serious and/or

transaminase [AST/SGOT] or alanine transaminase [ALT/SGPT]);
Subjects who have used any investigational medication within 30
days prior to the first dose of study medication.
[0386] Other Eligibility Criteria Considerations: To assess any
potential impact on subject eligibility with regard to safety, the
investigator must refer to the following document(s) for detailed
information regarding warnings, precautions, contraindications,
AEs, and other significant data pertaining to the investigational
product(s) being used in this study: Nelotanserin Investigator's
Brochure.
[0387] Screening Failures: Screen failures are defined as subjects
who sign an informed consent form (ICF) for the study but are never
subsequently randomized and who do not enter the single-blind
placebo run-in period. A minimal set of screen failure information
is required including demography, screen failure details,
eligibility criteria, and any AEs. Subjects who are screen failures
may be rescreened once only after approval by the study Medical
Monitor.
[0388] Withdrawal Criteria: A withdrawal from the study is defined
as withdrawing any time after entering the single-blind placebo
run-in period and before completion of the end of study visit
(Visit 5). Subjects who permanently discontinue use of
investigational product will be considered to be withdrawn from the
study. Subjects may withdraw from the study at any time and for any
reason. The investigator (or designee) must document the reason for
withdrawal in the Study Conclusion section of the case report form
(CRF). Information related to AEs will continue to be collected as
per usual procedures on subjects who have discontinued
investigational product. Withdrawn subjects will not be replaced.
The reasons for subject withdrawal will be recorded and may
include, but are not limited to: Any clinical AE, laboratory
abnormality, or other medical condition or situation occurs such
that continued participation in the study would not be in the best
interest of the subject in the opinion of the investigator;
Significant protocol violation; Subject requests to discontinue for
any reason; it is important to determine whether the withdrawal of
consent is primarily due to an AE, lack of efficacy, or other
reason; Subjects don't meet the eligibility criteria at baseline
(Visit 4). The above reasons do not automatically lead to
withdrawal from the study in all cases. The final decision will be
based on consultation between the principal investigator and the
study Medical Monitor, with the ultimate decision by the principal
investigator or subject. If a subject meets discontinuation
criteria during treatment, an Early Termination Visit will be
required.
[0389] Subject Withdrawal Procedures: If a subject is prematurely
discontinued from treatment with the investigational product(s),
the investigator must make every effort to perform the evaluations
scheduled for the Early Termination Visit (Table 8). In the case
where the subject permanently discontinues study medication between
scheduled clinic visits he/she should be recalled to the clinic as
soon as possible and preferably within 7 days of stopping study
medication for the Early Termination Visit; it is important to
record the date of the last study dose.
[0390] Lost to follow-up: If a subject is lost to follow-up, every
effort must be made by study center personnel to contact the
subject, inquire about the reason for discontinuation/withdrawal,
and follow up with any unresolved AEs/serious adverse events
(SAEs). A minimum of 3 attempts at contact should be made with 1
contact being by certified letter. All measures taken to contact
the subject and information received during those attempts must be
documented.
[0391] Investigational Product and Other Study Treatment:
Nelotanserin 20 mg tablets and matching placebo tablets are
composed of an immediate-release, blue, oblong shaped tablet
containing common pharmaceutical excipients in a compacted powder
blend. The excipients used for the proposed clinical program are
commonly available, generally regarded as safe, and tested against
appropriate compendial acceptance criteria. The tablets are coated
with a cosmetic colored film-coat. Lactose monohydrate is the only
excipient used in the manufacture of RVT-102 tablets that is
animal-sourced. The vendor source of this excipient has certified
that ingredients used in the manufacture of lactose monohydrate are
Bovine spongiform encephalopathy (BSE)/transmissible spongiform
encephalopathy (TSE) free.
[0392] Randomization/Treatment Assignment: During the screening and
the single-blind placebo run-in period, subjects will be identified
by their initials, screening number and date of birth. Subjects who
meet all screening eligibility criteria at Visit 2 will receive
single-blind placebo (2.times.placebo tablets) for up to 3 weeks
during the single-blind placebo run-in period. The tablet will be
administered once-daily in the evening, at approximately 1 hour
before bedtime. The subject will be instructed to take the study
drug around the same time each day. If subjects continue to meet
all eligibility criteria, they will be randomized and assigned a
randomization identification number (three digits). Both screening
and randomization numbers will be used to identify the subject on
any related study documents. The Investigator will keep a record
relating the names of the subjects to their identification numbers,
to allow easy checking of data in subject files, when required. A
central randomization process (IVRS) will be utilized. The
investigative sites will be provided a 4 digit (e.g. 1001)
randomization number (randnum) and a 3 digit (e.g. 123) kit ID
(kitid). Both the randnum and kitid will be entered on the CRFs for
each subject. Eligible subjects will be randomized (1:1) to either
the nelotanserin 80 mg treatment group or the placebo group during
the double-blind period. The randomization will be stratified by
whether the subjects will continue to take clonazepam or melatonin
concurrently with the study treatment. The study medications used
in the trial are nelotanserin 20 mg and matching placebo tablets.
Subjects randomized to nelotanserin 80 mg will receive two (2) 20
mg nelotanserin tablets (40 mg/day) for 5 days before the dose is
titrated to four (4) 20 mg nelotanserin tablets (80 mg/day) for the
remainder of the double-blind period. In order to mask the
treatment assignment, subjects randomized to placebo will similarly
receive two (2) placebo tablets for 5 days and then four (4)
matching placebo tablets for the remainder of the double-blind
period.
[0393] Blinding: The 20 mg Nelotanserin and matching placebo
tablets will be identical in appearance.
[0394] Concomitant Medications and Non-Drug Therapies:
[0395] Permitted Medications and Non-Drug Therapies: Quetiapine
<25 mg/day will be allowed if the dose is stabilized for at
least 4 weeks prior to screening and the subject is expected to
continue on this stable dose throughout the study; Low dose
clonazepam (.ltoreq.1 mg/day) or melatonin will be allowed if the
dose is stabilized for at least four weeks prior to screening and
the subject is expected to continue on this stable dose throughout
the study; Subjects taking antiparkinsonian drugs (eg, levodopa)
must be on stable dosage for at least 4 weeks prior to screening
and expect to continue the stable regimen throughout the study;
Subjects taking acetylcholinesterase inhibitors (AchEIs) or
memantine must be on stable dosage for at least 4 weeks prior to
screening and expect to continue the stable regimen throughout the
study
[0396] Prohibited Medications and Non-Drug Therapies: Prohibited
medications include any medications that may interfere with study
assessment during the single-blind placebo run-in and treatment
periods as shown in Table 7.

allowed in the study. Venlafaxine and mirtazapine which may induce
RBD behaviors.
[0398] Meals and Dietary Restrictions: The study medication can be
administered with or without food. Subjects should refrain from
consumption of grapefruit or grapefruit juice due to potential to
raise RVT 102 concentrations.
[0399] Study Assessments and Procedures:
[0400] Time and Events: The Time and Events Schedule displays each
study assessment and procedure along with the time of occurrence.
All study assessments should be conducted by the investigator,
and/or a suitably qualified designee approved and documented for
this study. All raters will be trained and certified or otherwise
deemed qualified by the Sponsor to perform the specific rating
scales in this study. It is important that all efforts be made to
ensure visits occur according to the protocol schedule. In the
event there is a conflict with a required visit, a 10 day window
can be exercised. This includes a -3 day and +7 day window. During
the single blind placebo run-in period, the -3 day window is not
allowed since critical data are required to be collected for a 2
week period in order to confirm eligibility into the double-blind
randomized period. Visits should not be scheduled relative to the
baseline visit. If the visit window is used, the subsequent visit
or contact should be calculated from the date of the previous
visit. Information will be recorded in the source documents and,
where appropriate, the CRF. If medical assessments are scheduled
for the same nominal time, then the assessments should be given
after cognitive testing and occur in the following order whenever
possible: 12-lead Electrocardiogram (ECG), Vital Signs, Blood
draws.
[0401] Screening Period (up to 28 days before Visit 2): At Visit 1
and during the screening period, subjects will be screened for
eligibility. An ICF will be signed by each subject, if they are
able, or by the caregiver with subject assent. An ICF will also be
signed by the caregiver before any study-specific procedures are
performed. Subjects will be screened according to study
inclusion/exclusion criteria. Subjects who do not qualify for the
study during this period will be considered screen failures.
Subjects who are screen failures during the Screening Period may be
rescreened after discussion with the Medical Monitor. Note:
subjects who are screen failures may be rescreened only once.
[0402] Single-Blind Run-In Period (Period A) (Period A, Up to 21
days): At Visit 2, subjects who meet all study screening criteria
will enter a Single-Blind Placebo Run-In Period (Period A).
Investigational product will be dispensed. Subjects will be
instructed to take the investigational product (2 tablets) once
daily in the evening, at approximately 1 hour before bedtime. Visit
2 assessments and procedures will be performed according to Table 8
below. Subjects will wear ActiGraph activity monitors on both of
their wrists during sleep throughout the study.
[0403] Sleep Lab Visit (Visit 3): At Visit 3, after the subject
completes 2 weeks of placebo run-in treatment, the subject will
participate in a whole-night video-PSG study at a specified sleep
lab, during which his/her RBD behaviors will be evaluated while
continuing his/her placebo treatment. To allow subjects to
acclimate to the sleep lab environment, subjects will spend a
minimum of two (preferably consecutive) nights at the local sleep
lab. During this study, the subject must have at least one
qualifying night of REM sleep. A qualifying night of REM sleep is
defined as a night with REM sleep duration of .gtoreq.10 minutes.
If a subject cannot achieve one or more qualifying nights of REM
sleep, the video-PSG study may be repeated for up to 2 nights as
unscheduled visit(s). If a new diagnosis of sleep apnea is made
during the sleep study, the sleep apnea may be treated, and up to 2
additional nights of sleep lab may be performed upon approval of
the medical monitor. Should this occur, 2 qualifying nights of
sleep study without apnea should be completed and sent to the
central reviewer. The video-PSG data will be reviewed by a central
reviewer to determine if the subject meets the randomization
criteria. During this time, the subject will continue to receive
placebo until being notified to return for the next visit. This
period can be extended for 7 days to accommodate Visit 4
scheduling. Double-blind Treatment Period (Period B):
Baseline/randomization (Visit 4--Day 0): At Visit 4 (Day 0), prior
to ingestion of double-blind investigational product, baseline
assessments will be performed to determine subject eligibility. To
qualify for randomization at Visit 4, subjects must meet
protocol-specified criteria for RBD behaviors at baseline, return
unused study medication, be considered capable of completing study
assessments, and continue to meet all other eligibility
requirements. Eligible subjects will be randomized 1:1, stratified
by use of clonazepam/melatonin, to either the nelotanserin 80 mg
treatment group or the placebo group. During the four week
double-blind treatment period (Period B), investigational product
will be dispensed at Visit 4 (Day 0) and will be returned at Visit
5 (Day 28), the final study visit. Subjects randomized to
nelotanserin 80 mg will receive two (2) 20 mg nelotanserin tablets
(40 mg/day) for 5 days before the dose is titrated to four (4) 20
mg nelotanserin tablets (80 mg/day) for the remainder of the
double-blind period. In order to mask the treatment assignment,
subjects randomized to placebo will similarly receive two (2)
placebo tablets for 5 days and then four (4) matching placebo
tablets for the remainder of the double-blind period. Subjects will
be reminded to take the blinded investigational product around the
same time each evening, at approximately 1 hour before bedtime.
During the double-blind period, study drug dose may be reduced only
once at the decrement of one or more tablets at the discretion of
the investigator for safety/tolerability reasons. The study drug
dose may return to 80 mg after safety/tolerability events subside.
All dose adjustments must take place after a safety evaluation at
the study clinic.
[0404] Phone call (Day 14): There will be a phone contact
approximately 14 days into the double-blind period during which
safety/tolerability issues with study treatment, if any, will be
addressed and AEs will be collected. The site personnel will also
ensure that the subject is in compliance with study drug dosing and
protocol procedures, including continuing to record sleep behaviors
and to wear ActiGraph activity monitors nightly at home.
[0405] Final Study Visit (Visit 5 on Day 28): Subjects will return
to the clinic for Visit 5 (Day 28) to complete final study
assessments. The subject will participate in a whole-night
video-PSG study at a specified sleep lab for least two (preferably
consecutive) nights at the end of the double-blind period (Visit
5), during which his/her RBD behaviors will be evaluated. During
this period, at least one qualifying night of REM sleep is
required. A qualifying night of REM sleep is defined as REM sleep
duration of 10 minutes or more. If a subject cannot achieve one or
more qualifying nights of REM sleep, the video-PSG study may be
repeated for up to two nights as unscheduled visit(s). Subjects who
discontinue study drug treatment early must contact the study site
personnel as soon as possible to schedule the whole-night video-PSG
study. Study assessments and procedures will be performed according
to Table 8 below. The order of assessments should remain
consistent. If possible, other assessments, including ECG, vital
signs, and blood draws, should be performed after cognition
testing. Subjects will continue to wear ActiGraph activity monitors
on both of their wrists during sleep during the double-blind
period. Generally, a 10 day visit window (-3/+7 days) will be
allowed to accommodate the scheduling. Subjects who prematurely
discontinue double-blind investigational product should be
encouraged to return to the clinic for an Early Termination Visit
and the Visit 5 assessments and procedures will be completed.
[0406] Unscheduled Visit: The subject may be requested to return to
the clinic for an unscheduled visit for the following reasons:
Repeat the whole night sleep study; Reduce the dose due to
tolerability or safety concerns (the dose decrement can be one or
more tablets, and dose reduction can only occur once during the
double-blind period); Titrate the dose back to 80 mg after dose
reduction; Perform additional safety assessments as requested by
the investigators. Follow-up Visit/Phone Call: For subjects who
will not be participating in the open-label study, a follow-up
visit or phone call (as deemed appropriate by the investigators)
will occur approximately 14 days after the final study visit.
During this visit/phone call, the investigator will review and
record subjects' post-study medications and AEs. Additional safety
assessments (eg, follow-up ECG and clinical lab assessments) as
deemed necessary by the investigators may be performed at this
visit.

protocol for this patient population. Note that hepatitis screening
performed within 3 months of Visit 2 is acceptable and will not
require repeat testing for the purpose of this clinical study.
.sup.7A blood sample for pharmacokinetic analysis w ill be
collected at Visit 4 and Visit 5.
[0407] Critical Baseline Assessments: Subjects need to continue to
meet the eligibility criteria for REM sleep behaviors: A subject
must experience frequent RBD episodes prior to Screening (Visit 1).
In addition, there are at least four (4) RBD episodes (one or more
of which must include complex RBD events) per 10 minutes of REM
sleep during 1 or more qualifying night(s) based on a central
review of video-PSG data obtained from the sleep lab during the
single-blind placebo run-in period.
[0408] Efficacy Assessments: All study assessments should be
conducted by the investigator, and/or a suitably qualified
designee, all of whom will be trained and certified to administer
these measures for this study. Every effort should be made for the
same person to conduct specific assessments on each individual
subject at each study visit. Assessments will be monitored for
quality. Screening and baseline assessments along with accompanying
data will be reviewed to ensure that subjects meet the inclusion
criteria. Other assessments will be monitored by using data
collected.

[0410] REM Sleep Behaviors Observed with Video-Polysomnography in
Sleep Lab: Whole-night video-PSG study will be performed according
to the current standards. Video-PSG will provide the information on
number of REMs, duration of REMs, and number and nature of RBD
behaviors. The video data during REM will be reviewed centrally
following a methodology included in the study manual. The
procedures are briefly summarized below. The video recordings will
be reviewed and analysed to determine behaviors characteristic of
RBDs. A panel of 3 to 4 members will be assembled and will consist
of board-certified neurologists with specialization in sleep
medicine and video analysis experts. The video will be analyzed by
one of the panel members with supervision by the panel. All
ambiguous cases will be adjudicated by the panel. All visible
movements regardless of type, amplitude, and duration will be
analyzed. Every movement will be classified according to type of
movement, topographical involvement (involvement of body parts),
and presence of an associated arousal. All movements will be
dichotomized into elementary/simple and complex/major.
Elementary/simple movements are defined as small involuntary
movements or stereotyped movements. Complex/major movements are
defined as movements showing complexity of action and involving
more muscle groups simultaneously or violent movements.
Vocalizations (talking, crying, laughing, yelling, swearing) are
also analyzed; the apparent emotional state (positive, e.g., when
the subject is laughing; negative, e.g., when the subject is
screaming or crying; neutral) will be assessed for complex/major
behaviors and vocalizations. An RBD behavior is defined as a motor
behavior and/or vocalization with a purposeful component, seemingly
expressive of a subject's mentation. Comfort moves, neck myoclonus,
respiratory noises, and events related to arousals will be
excluded. The frequencies of RBD behaviors will be scaled to a
function of time to compute the number of RBD behaviors per 10
minutes of REM sleep. The severity RBD behaviors will be based on
viewer ratings. Specifically, each behavior will be rated
separately into one of three severity categories: mild, moderate,
or severe. A composite measure of both RBD behavior frequency and
severity will be derived based on the weighting of each RBD
behavior by its severity, with mild RBD behaviors receiving a
weight of 1, moderate RBD behaviors receiving a weight of 2, and
severe RBD behaviors receiving a weight of 3. The composite will
then be calculated as the sum of products across all behaviors and
scaled to a function of time to compute the severity-weighted RBD
behaviors per 10 minutes of REM sleep. Clinician's Global
Impression of Change--REM Sleep Behaviors: The Clinician's Global
Impression of Change-RBD (CGIC-RBD) is an ordinal scale of global
evaluation which assesses the change in overall status with RBD
relative to the start of treatment. The scale has only 1 item that
measures global change of overall status (improvement or worsening)
with RBD by the investigator on a 7-point scale from 1 to 7, where
1=very much better and 7=very much worse. The CGIC-RBD will be
assessed in accordance with the time and events schedule described
in Table 8.
[0411] RBD-related Injuries: RBD-related injuries to the subject or
the bed partner will be captured on a daily RBD diary to be
completed by the bed partner or caregiver with information provided
by the subject as needed. The number of injuries to either the
subject or the bed partner will be recorded.
[0412] Dramatic Dreams: Dramatic dreams that are frightening, very
unpleasant, and/or involve attacking or chasing scenes and their
content will be captured on a daily RBD diary to be completed by
the bed partner or caregiver with information provided by the
subject as needed. The number of dramatic dreams will be
recorded.
[0413] Scales for Outcomes of Parkinson's Disease--SleepScales for
Outcomes in Parkinson's disease (SCOPA)--Sleep is a validated short
questionnaire that is used to assess nighttime sleep (NS) problems
and daytime sleepiness (DS) in subjects with Parkinson's disease.
It takes about 10 min to complete. The NS subscale addresses NS
problems in the past month and includes 5 items with 4 response
options. The maximum score of this subscale is 15, with higher
scores reflecting more severe sleep problems. One additional
question evaluates overall sleep quality on a 7-point scale
(ranging from slept very well to slept very badly). The score on
this item is not included in the score of the NS scale but is used
separately as a global measure of sleep quality. The DS subscale
evaluates DS in the past month and includes 6 items with 4 response
options, ranging from 0 (never) to 3 (often). The maximum score is
18, with higher scores reflecting more severe sleepiness.
[0414] Visual Analog Scale for Bed Partner Sleep Quality: The bed
partner's sleep quality will be assessed using a VAS, with one end
of the VAS (marked with "0") representing "not able to sleep at
all" and the other end of the VAS (marked with "10") representing
"uninterrupted sleep". The bed partner will place an X on the scale
indicating how well he/she has slept over the last 7 days. A bed
partner is defined as the person who sleeps in the same bedroom as
the subject.
[0415] Visual Hallucinations and Auditory Hallucinations: Subjects
and caregivers will together complete a daily study diary, in which
they will document the frequency and severity of visual and
auditory hallucinations experienced by the subject. This diary will
be completed each evening at a defined time (i.e. within one hour
of the time at which the diary is first completed during the
study). The subject and caregiver will note whether the subject
experiences any hallucinations over the course of the day, and will
describe the approximate number of hallucinations and their
duration, the quality of the hallucinations, and the degree to
which the hallucinations are disturbing to the subject and
caregiver. This daily study diary will be reviewed by the
investigator according to the time and events schedule described
above.
[0416] Objective Sleep Parameters Measured by Polysomnography:
Objective sleep parameters will be measured with PSG. These will
include wake after sleep onset (WASO), number of arousals (AR),
sleep efficiency (SE), % and duration of sleep stages (Stage 1
Non-REM [NREM] [N1], Stage 2 NREM [N2], Stage 3 NREM [N3], and
REM), latency to Stage N1, Stage N2, Stage N3, and REM, latency to
sleep, total sleep time (TST), REM start and end time(s), total
recording time-"lights out" to "lights on" (TRT), duration of Stage
W (wakefulness), periodic leg movements of sleep index (PLMSI),
periodic leg movements of sleep arousal index (PLMSArI), total
apnea hypopnea index (AHI), and REM AHI.
[0417] Physical Activity During Sleep Measured with ActiGraph:
ActiGraph wGT3X-BT will be used to objectively measure physical
activity during sleep. The subject will be instructed to wear the
monitors on both wrists every night and record their sleep times.
The "total count" captured during sleep time by the activity
monitors will be used as the measure of physical activity during
sleep.
[0418] Safety and Screening Assessments:
[0419] Adverse Events: The investigator or site staff is
responsible for detecting, documenting, and reporting events that
meet the definition of an AE or SAE.
[0420] Definition of Adverse Events:
[0421] An AE is any untoward medical occurrence associated with the
use of a drug in humans, whether or not considered drug related.
Therefore, an AE can be ANY unfavorable and unintended sign
(including an abnormal laboratory finding or vital sign
measurement), symptom, or disease temporally associated with the
use of a medicinal product, without any judgment about
causality.
[0422] Events meeting the definition of an AE include: Exacerbation
of a chronic or intermittent pre-existing condition including
either an increase in frequency and/or intensity of the condition;
New conditions detected or diagnosed after investigational product
administration even though it may have been present prior to the
start of the study; Signs, symptoms, or the clinical sequelae of a
suspected drug interaction; Signs, symptoms, or the clinical
sequelae of a suspected overdose of either investigational product
or a concomitant medication; Clinically significant abnormal
findings (laboratory test results, vital signs, physical
examination findings, ECGs, radiologic exams or other studies)
should be recorded as AEs. A "clinically significant" finding is
one that affects clinical management, including additional visits,
monitoring or referrals, diagnostic tests or alteration of
treatment, or that is considered clinically significant by the
investigator. A clinically significant finding may be a change in a
test that has previously been abnormal but now requires additional
action; When a medical or surgical procedure is performed, the
condition that leads to the procedure should be recorded as the
AE.
[0423] Events that do not Meet the Definition of an AE Include:
[0424] Anticipated day-to-day fluctuations or expected progression
of pre-existing disease(s) or condition(s) present or detected at
the start of the study unless judged by investigator to be more
severe than expected for the subject's underlying condition;
Abnormal laboratory, ECG, or vital sign measurements that are not
labelled clinically significant (see definition above); Situations
where an untoward medical occurrence did not occur (social and/or
convenience admission to a hospital); Overdose in the absence of
other AEs will not be reported as an AE in its own right; Changes
in Columbia Suicide Severity Rating Scale (C-SSRS) during the
course of the study indicating worsening should be evaluated by the
investigator for clinical significance, and if clinically
significant (e.g., alteration in medical care or intervention is
required), an associated AE should be recorded, if present. The AE
should be the primary underlying clinical manifestation assessed as
clinically significant, and not the change in score itself; Adverse
events are recorded from the time that informed consent is signed,
including those that occur during the Single-Blind Placebo Run-in
Period. Treatment emergent adverse events (TEAEs) are defined as
those that occur on or after the date of the first dose of
investigational product. Definition of Serious Adverse Event:
[0425] An AE is considered serious if, in the view of either
investigator or sponsor, it results in any of the following
outcomes: Death, A life-threatening AE, An AE is considered
"life-threatening" if, in the view of either the investigator or
sponsor, its occurrence places the patient or subject at immediate
risk of death. It does not include an AE that, had it occurred in a
more severe form, might have caused death. The determination of
whether an AE is life threatening can be based on the opinion of
either the investigator or sponsor. Thus, if either believes that
it meets the definition of life-threatening, it must be considered
life-threatening for reporting purposes. Inpatient hospitalization
or prolongation of existing hospitalization, A persistent or
significant incapacity or substantial disruption of the ability to
conduct normal life functions, or A congenital anomaly/birth
defect. Important medical events that may not result in death, be
life threatening, or require hospitalization may be considered
serious when, based upon appropriate medical judgment, they may
jeopardize the patient or subject and may require medical or
surgical intervention to prevent one of the outcomes listed in this
definition. Examples of such medical events include allergic
bronchospasm requiring intensive treatment in an emergency room or
at home, blood dyscrasias or convulsions that do not result in
inpatient hospitalization, or the development of drug dependency or
drug abuse. This definition of an SAE permits either the sponsor or
the investigator to decide if an event is serious. Because SAEs are
critically important for the identification of significant safety
problems, the United States Food and Drug Administration (FDA)
believes taking into account both the investigator's and the
sponsor's assessment is important. For example, the investigator's
perspective may be informed by having actually observed the event,
and the sponsor is likely to have broader knowledge of the drug and
its effects to inform its evaluation of the significance of the
event. If either the sponsor or investigator believes that the
event is serious, the event must be considered serious and
evaluated by the sponsor for possible expedited reporting. Time
Period and Frequency for Collecting Adverse Event and Serious
Adverse Event Information: Collection of AEs and SAEs will begin at
the time a subject signs informed consent and continues until the
last study visit/follow-up phone contact, as shown in the Time and
Events Schedule (Table 8). SAEs that are spontaneously reported by
the subject or subject representative or discovered by the
investigator or designee after the last study visit/follow-up phone
contact and up to 30 days after the last dose of investigational
product must be collected and reported. All SAEs will be recorded
and reported to the Sponsor within 24 hours of the investigator
becoming aware of the SAE. Investigators are not obligated to
actively seek AEs or SAEs in former study subjects. However, if the
investigator learns of any SAE, including a death, at any time
after a subject has been discharged from the study, and he/she
considers the event reasonably related to the investigational
product or study participation, the investigator must promptly
notify the sponsor or sponsor representative.
[0426] Assessment of Adverse Events: The severity of each AE will
be assessed by the investigator, or designee approved and
documented for this study, as mild, moderate, or severe based on
the below definitions: Mild: Event that is usually transient and
may require only minimal treatment or therapeutic intervention. The
event does not generally interfere with usual activities of daily
living. Moderate: Event that is usually alleviated with additional
specific therapeutic intervention. The event interferes with usual
activities of daily living, causing discomfort, but poses no
significant or permanent risk of harm to the subject. Severe: Event
that interrupts usual activities of daily living or significantly
affects clinical status, or may require intensive therapeutic
intervention. Outcome will be assessed using the following
categories: recovered/resolved, not recovered/not resolved,
recovered/resolved with sequelae, fatal, or unknown. In addition
the investigator must determine the relationship between the
administration of study medication and the occurrence of an AE/SAE
as Not Suspected or Suspected as defined below: Not suspected:
Means a causal relationship of the AE to study medication
administration is unlikely or remote, or other medications,
therapeutic interventions, or underlying conditions provide a
sufficient explanation for the observed event. Suspected: Means
there is a reasonable possibility that the administration of study
medication caused the AE. "Reasonable possibility" means there is
evidence to suggest a causal relationship between the study drug
and the AE. Causality should be assessed and provided for every
AE/SAE based on currently available information. Causality is to be
reassessed and provided as additional information becomes
available. Method of Detecting Adverse Events and Serious Adverse
Events: Care will be taken not to introduce bias when detecting AEs
and/or SAEs. Open-ended and non leading verbal questioning is the
preferred method to inquire about AE occurrence. Appropriate
questions include: "How are you feeling?", "Have you had any
(other) medical problems since your last visit/contact?", "Have you
taken any new medicines, other than those provided in this study,
since your last visit/contact?"
[0427] Follow-up of Adverse Events and Serious Adverse Events:
After the initial AE/SAE report, the investigator is required to
proactively follow each subject at subsequent visits/contacts. All
AEs and SAEs will be followed until resolution, until the condition
stabilizes, until the event is otherwise explained, or until the
subject is lost to follow-up.
[0428] Physical Examinations: Physical examinations will be
performed as indicated in Table 8. A complete physical examination
will include, at a minimum, assessment of the cardiovascular,
respiratory, gastrointestinal, and neurological systems.
Neurological examinations will include assessment of gait, balance,
coordination, cranial nerves and motor and sensory systems. A
brief, symptoms-directed physical examination will include, at a
minimum, assessments of the lungs, cardiovascular system, and
abdomen (liver and spleen). Physical examinations at Screening and
Visit 5/Early Termination will be full examinations; at all other
study visits, an abbreviated physical examination is required. Any
clinical significant findings at the screening visit will be
considered medical history. The investigator will assess whether
any changes from the screening visit in physical and neurological
examinations reflect AEs.
[0429] Vital Signs: Vital signs will be measured after the subject
has been in the seated position for 5 minutes and will include
temperature, systolic and diastolic blood pressures, pulse rate,
and respiratory rate. Body weight will also be recorded at each
visit and height will be recorded at Screening. Blood pressure will
also be measured in the supine and standing positions. Blood
pressure in the supine position will be measured after the subject
has been supine for a minimum of 3 minutes; blood pressure in the
standing position will be measured after the subject has been
standing for a minimum of 3 minutes. Both results will be reported
on the appropriate CRF pages. The investigators will assess the
clinical significance of any decline in blood pressure associated
with the positional change. Any clinical significant findings at
the screening visit will be considered medical history. The
investigator will assess whether any changes from the screening
visit in vital signs reflect AEs.
[0430] Electrocardiogram: Two tracings of 12-lead ECGs 15 min apart
will be obtained at each time point during the study (Table 8)
using an ECG machine that automatically calculates the heart rate
and measures RR, PR, QRS, QT, QTcB (QT corrected for heart rate
using Bazett's method), and QTcF (QT corrected for heart rate using
Fridericia's method) intervals with the subject in the supine
position. The investigator or designated qualified physician at the
site will evaluate the Screening ECG for any abnormalities that
should exclude the subject from the study or require acute
additional evaluation or intervention. They should also evaluate
the ECG printouts for all subsequent visits for any new
abnormalities. Any abnormality should include a determination of
clinical significance. A clinically significant ECG finding is one
that requires additional medical evaluation or treatment. Abnormal
ECG findings that are clinically significant should be recorded as
AEs on the CRFs or Medical History if noted at the screening
visit.
[0431] Clinical Safety Laboratory Assessments: All
protocol-required laboratory assessments, as defined in Table 3,
must be conducted in accordance with the Study Procedures Manual
and Protocol Time and Events Schedule (Table 8). A central
laboratory will be utilized for this clinical protocol. Abnormal
laboratory tests that are clinically significant should also be
recorded as AEs on the CRF or Medical History if noted during
screening. Clinically significant means that the confirmed abnormal
test result has an impact on patient management, including
additional monitoring diagnostic tests, or changes in treatment.
The same standard applies to additional non-protocol specified
laboratory assessments that are performed at the institution's
local laboratory and result in a change in subject management
(i.e., monitoring, diagnostic tests, or any alteration in
treatment). Hematology, clinical chemistry, urinalysis, and other
screening laboratory parameters to be tested are listed in Table
9.

glutamyltransferase; HBsAg = hepatitis B surface anitgen; hCG =
human chorionic gonadotropin; MCH = mean corpuscular hemoglobin;
MCV = mean corpuscular volume; RBC = red blood cell; TSH = thyroid
stimulating hormone; WBC = white blood cell.
[0432] All laboratory tests with values that are considered
clinically significantly abnormal during participation in the study
or within 7 days after the last dose of investigational product
should be repeated until the values return to normal or baseline or
until the value stabilizes. If such values do not return to normal
within a period judged reasonable by the investigator, the etiology
should be identified and the Medical Monitor notified.
[0433] Assessment of Suicidality: Subjects will be assessed for
suicidality before and during the study using the Columbia Suicide
Severity Rating Scale (C-SSRS). Subjects considered to be at
significant risk will be excluded from the study. The C-SSRS is a
brief measure which is designed to assess severity and change of
suicidality by integrating both behavior and ideation. It assesses
intensity of ideation (a potentially important marker of severity),
specifically asking about frequency, duration, controllability,
deterrents, and reasons for the ideation which was most severe
during the respectively assessed timeframe. Suicidal behavior is
also assessed by asking further questions to categorize the
behaviors into actual, interrupted, or aborted attempts; as well as
preparatory and non-suicidal self-injurious behavior. The C-SSRS
will be completed by a rater trained and certified to administer
this scale. Any change in C-SSRS score indicating the presence of
suicidality should be evaluated by the investigator for clinical
significance to determine continued study eligibility and
appropriate clinical actions (including but not limited to a
referral to a mental health professional). Clinically meaningful
suicidal ideation, suicidal behavior and completed suicide should
be recorded as AEs.
[0434] Assessment of Parkinsonism: Subjects will be assessed for
signs of Parkinsonism before and during the study using the Unified
Parkinson's Disease Rating Scale (UPDRS) Part II and Part III (Fahn
1987). The UPDRS Part II consists of 13 items for self-reported
abilities on activities of daily life (ADLs), including speech,
swallowing, handwriting, dressing, falling, salivating, walking,
and tremor. The UPDRS Part III is a 14-item clinician-scored motor
evaluation including rigidity, figure taps, tremor at rest,
posture, leg agility, bradykinesia. UPDRS Part II yields a score
range of 0 to 52 (inclusive), while UPDRS Part III scores range
from 0 to 108 (inclusive), with higher scores indicating greater
disability for both parts.
[0435] Mini-Mental State Examination: The MMSE (Folstein 1975)
consists of 11 tests of orientation, memory (recent and immediate),
concentration, language, and praxis. Scores range from 0 to 30,
with lower scores indicating greater cognitive impairment. It is
based on the performance of the subject and takes approximately 5
to 10 minutes to administer.
[0436] Montreal Cognitive Assessment Scale: The Montreal Cognitive
Assessment (MoCA) scale (Nasreddine 2005) is designed to assess
different cognitive domains: attention and concentration, executive
functions, memory, language, visuo-constructional skills,
conceptual thinking, calculations, and orientation. Ongoing work
with Biundo et al and others suggests that in PD and DLB, MoCA is
more sensitive to detect the earliest stage, whereas MMSE is more
sensitive in the more advanced stage, leading to a recommendation
by the EU Joint Programme-Neurodegenerative Disease Research (JPND)
Working Group on Longitudinal Cohorts that both measures be
included in studies of these patient populations. Time to
administer the MoCA is approximately 10 minutes. The total possible
score is 30 points; a score of 26 or above is considered
normal.
[0437] Pregnancy: The study will allow female subjects who are
postmenopausal for at least 24 consecutive months who have
undergone surgical removal of uterus or removal of both
ovaries.
[0438] Pharmacokinetic Assessments: Two blood samples for
pharmacokinetic analysis of plasma nelotanserin and M1 metabolite
concentration will be collected at the time points indicated in
Table 8. The actual date and time of each blood sample collection,
and the date and time of the dose of study treatment on the day of
pharmacokinetic sampling will be recorded. For the pharmacokinetic
sample at Visit 5, the date and time of the previous dose of study
treatment also will be recorded.
[0439] Statistical Considerations and Data Analyses:
[0440] Hypotheses: For the primary efficacy endpoint analysis, the
null hypothesis to be tested is that the magnitude of change in
frequency per 10 minutes of REM sleep of RBD behaviors (simple and
major movements and vocalizations), based on video assessment
conducted at a sleep lab, from baseline (the whole-night sleep
study on the last day of the single-blind placebo run-in period) to
the end of treatment (the whole-night sleep study on the last day
of treatment), will be statistically equivalent for nelotanserin
and placebo treatment arms.
[0441] For the secondary efficacy endpoint analyses, the following
null hypotheses will be tested: The proportion of RBD behaviors
rated as severe, based on video assessment conducted at a sleep
lab, from baseline to the end of treatment will be statistically
equivalent for nelotanserin and placebo treatment arms. The
magnitude of change on a composite of both severity and frequency
of RBD behaviors, based on video assessment conducted at a sleep
lab, from baseline to the end of treatment will be statistically
equivalent for nelotanserin and placebo treatment arms. The
magnitude of change in the number of nights with injurious
behaviors to the subject or the bed partner per week, based on self
or caregiver reports from the daily study diary, from baseline to
the end of treatment will be statistically equivalent for
nelotanserin and placebo treatment arms. The magnitude of change in
the number of nights with dramatic dreams per week, based on self
or caregiver reports from the daily study diary, from baseline to
the end of treatment will be statistically equivalent for
nelotanserin and placebo treatment arms. The magnitude of change in
nighttime sleep quality, based on the SCOPA-Night subscale
sumscore, from baseline to the end of treatment will be
statistically equivalent for nelotanserin and placebo treatment
arms. The magnitude of change in daytime sleepiness, based on the
SCOPA-Day subscale sumscore, from baseline to the end of treatment
will be statistically equivalent for nelotanserin and placebo
treatment arms. The magnitude of change in quality of bed partner
sleep, based on a VAS completed by the bed partner, from baseline
to the end of treatment will be statistically equivalent for
nelotanserin and placebo treatment arms. Clinicians' judgment of
overall change in RBD behaviors, based on the CGIC-RBD administered
at the end of treatment will be statistically equivalent for
nelotanserin and placebo treatment arms. The magnitude of change in
objective sleep parameters (including WASO; number of arousals;
sleep efficiency; duration of total sleep time [TST]; duration and
proportion of sleep time in Stage 1 NREM [N1], Stage 2 NREM [N2],
Stage 3 NREM [N3], and REM; latency to sleep; latency to Stage N1,
Stage N2, Stage N3, and REM; duration of wakefulness [Stage W];
periodic leg movements of sleep index [PLMSI]; periodic leg
movements of sleep arousal index [PLMSArI]; total apnea hypopnea
index [AHI]; and REM AHI.), based on assessments from PSG, from
baseline to the end of treatment will be statistically equivalent
for nelotanserin and placebo treatment arms. The magnitude of
change in nightly physical activity during sleep time, based on
total count assessment from the ActiGraph wGT3X-BT activity monitor
worn during the study, from baseline to the end of treatment will
be statistically equivalent for nelotanserin and placebo treatment
arms. The magnitude of change in total daily duration of VHs, based
on self and caregiver reports from the daily study diary, from
baseline to the end of treatment will be statistically equivalent
for nelotanserin and placebo treatment arms. The magnitude of
change in total daily duration of AHs, based on self and caregiver
reports from the daily study diary, from baseline to the end of
treatment will be statistically equivalent for nelotanserin and
placebo treatment arms.
[0442] For the safety endpoint analyses, the following null
hypotheses will be tested: Changes in subject-reported ability to
engage in ADLs, based on the UPDRS Part II, from baseline to the
end of treatment will be statistically equivalent for nelotanserin
and placebo treatment arms. Changes in clinician-reported
extrapyramidal signs, based on the UPDRS Part III, from baseline to
the end of treatment will be statistically equivalent for
nelotanserin and placebo treatment arms. The magnitude of change in
MMSE score from baseline to the end of treatment will be
statistically equivalent for nelotanserin and placebo treatment
arms. The magnitude of change in MoCA score from baseline to the
end of treatment will be statistically equivalent for nelotanserin
and placebo treatment arms.
[0443] Sample Size Considerations: The primary comparison of
interest is to compare change in the nightly frequency of
characteristic RBD behaviors in patients with LBD between
nelotanserin and placebo arms after a four week treatment period. A
sample size of 52 subjects (26 subjects per treatment arm) would
provide power (1-.beta.) of 0.80 to detect a 0.8 unit treatment
group difference in the change from baseline to end of treatment in
the nightly frequency of RBD behaviors measured by video assessment
conducted at a sleep lab, assuming SD of 1 unit, using an analysis
of covariance (ANCOVA) model with a single two-level between-groups
fixed effect and two covariates and a significance level for Type-I
error (.alpha.) of 0.05.
[0444] Analysis Populations: The efficacy analysis population will
consist of all randomized subjects who have taken at least one dose
of investigational product and who have at least one post-baseline
efficacy assessment. This will be the primary population used for
the efficacy analysis. The primary population for safety analyses
will be the Safety Population, which will consist of all subjects
who were randomized and took at least one dose of investigational
product.
[0445] Key Elements of Analysis Plan: The primary objective of this
study is to evaluate the efficacy and safety of nelotanserin in
reducing the nightly frequency of characteristic RBD behaviors
following four weeks of treatment. Descriptive statistics for all
efficacy and safety measures over the course of the study will be
presented. Continuous data will be summarized by means, SDs,
standard errors (SEs), medians, interquartile ranges (IQRs),
maximum observed value, minimum observed value, and number of
subjects. Categorical data will be summarized by frequency counts
and proportions. Listings will be sorted by sequence subject,
period and time. Summaries will be presented by treatment and time.
Version 9.2 or higher of the SAS system will be used to analyze the
data as well as to generate tables, figures, and listings. Further
details of analyses to be performed will be provided in the
statistical analysis plan. Analysis datasets will be constructed
using version SAS 9.2 or later following current CDISC guidelines.
Missing data will be imputed using the last observation carried
forward (LOCF) method. Details of imputation and any changes or
refinements necessary will be documented in the statistical
analysis plan (SAP). Depending on the extent of missing values,
further investigation may be made into the sensitivity of the
analysis results using different imputation methods.
[0446] Efficacy Analyses: Efficacy data will be summarized and
listed by treatment and assessment time by period and overall. For
treatment comparisons of change in efficacy endpoints of interest
across two time points (ie, baseline and end of treatment),
statistical significance of between-group differences in change in
values from baseline to end of treatment visits will be estimated
using univariate ANCOVA models that include treatment arm as a
fixed effect and both baseline value of the efficacy endpoint and
background treatment of melatonin/clonazepam as covariates. The
least squares means and standard errors for change in values from
baseline to end of treatment, the magnitude of least square mean
differences and 95% CIs for differences in means between treatment
arms, and p-values for the test of the fixed effect of treatment
will be estimated from these models for the following efficacy
endpoints: Change in frequency of RBD behaviors per 10 minutes of
REM sleep, based on video assessment conducted at a sleep lab at
baseline and at the end of treatment, Change in a composite of
frequency and severity of RBD behaviors, based on video assessment
conducted at a sleep lab at baseline and at the end of treatment,
Change in the number of nights with one or more injurious
behaviors, based on self or caregiver reports from the study daily
diary, averaged over the last 7 days of the single-blind placebo
run-in period and the last 7 days of the double-blind treatment
period, Change in the number of nights with one or more dramatic
dreams, based on self or caregiver reports from the study daily
diary, averaged over the last 7 days of the single-blind placebo
run-in period and the last 7 days of the double-blind treatment
period, Change in nighttime sleep quality, based on SCOPA-Night
subscale sumscore at baseline and at the end of treatment, Change
in daytime sleepiness, based on SCOPA-Day subscale sumscore at
baseline and at the end of treatment, Change in quality of bed
partner sleep, based on a VAS completed by the bed partner at
baseline and at the end of treatment, Change in clinicians'
judgment of overall change in RBD behaviors, based on the CGIC-RBD
administered at baseline and at the end of treatment, Change in
duration (in minutes) of WASO, based on the PSG conducted at a
sleep lab at baseline and at the end of treatment, Change in the
number of arousals, based on the PSG conducted at a sleep lab at
baseline and at the end of treatment, Change in sleep efficiency,
based on the PSG conducted at a sleep lab at baseline and at the
end of treatment, Change in duration (in minutes) of TST, based on
the PSG conducted at a sleep lab at baseline and at the end of
treatment, Change in duration (in minutes) of sleep time in sleep
Stage 1, based on the PSG conducted at a sleep lab at baseline and
at the end of treatment, Change in proportion of sleep time in
sleep Stage N1, based on the PSG conducted at a sleep lab at
baseline and at the end of treatment, Change in duration (in
minutes) of sleep time in sleep Stage N2, based on the PSG
conducted at a sleep lab at baseline and at the end of treatment,
Change in proportion of sleep time in sleep Stage N2, based on the
PSG conducted at a sleep lab at baseline and at the end of
treatment, Change in duration (in minutes) of sleep time in sleep
Stage N3, based on the PSG conducted at a sleep lab at baseline and
at the end of treatment, Change in proportion of sleep time in
sleep Stage 3, based on the PSG conducted at a sleep lab at
baseline and at the end of treatment, Change in duration (in
minutes) of sleep time in REM sleep, based on the PSG conducted at
a sleep lab at baseline and at the end of treatment, Change in
proportion of sleep time in REM sleep, based on the PSG conducted
at a sleep lab at baseline and at the end of treatment, Change in
latency (in minutes) to reach sleep Stage N1, based on the PSG
conducted at a sleep lab at baseline and at the end of treatment,
Change in latency (in minutes) to reach sleep Stage N2, based on
the PSG conducted at a sleep lab at baseline and at the end of
treatment, Change in latency (in minutes) to reach sleep Stage N3,
based on the PSG conducted at a sleep lab at baseline and at the
end of treatment, Change in latency (in minutes) to reach REM
sleep, based on the PSG conducted at a sleep lab at baseline and at

wakefulness (Stage W), based on the PSG conducted at a sleep lab at
baseline and at the end of treatment, Change in PLMSI, based on the
PSG conducted at a sleep lab at baseline and at the end of
treatment, Change in PLMSArI, based on the PSG conducted at a sleep
lab at baseline and at the end of treatment, Change in total AHI,
based on the PSG conducted at a sleep lab at baseline and at the
end of treatment, Change in REM AHI, based on the PSG conducted at
a sleep lab at baseline and at the end of treatment, Change in the
total count of physical activity during sleep, based on assessment
from the ActiGraph wGT3X-BT activity monitor at a sleep lab at
baseline and at the end of treatment, Change in total count of
physical activity, based on assessment from the ActiGraph wGT3X-BT
activity monitor worn in a controlled sleep environment, averaged
over the last 7 days of the single-blind placebo run-in period and
the last 7 days of the double-blind treatment period, Change in the
total daily duration (in minutes) of VHs, based on a study daily
diary completed jointly by subject and caregiver, at baseline and
at the end of treatment, Change in the total daily duration (in
minutes) of AHs, based on a study daily diary completed jointly by
subject and caregiver, at baseline and at the end of treatment. For
treatment comparisons of change in severity of RBD behaviors,
statistical significance of between-group differences in change in
proportion of severe RBD behaviors from baseline to end of
treatment visits will be estimated using a generalized estimating
equation (GEE) that includes treatment arm, visit, and the
interaction of treatment arm and visit as fixed effects and
background treatment of melatonin/clonazepam as a covariate. The
parameter coefficients and p-values for the tests of fixed effects
on the proportion of severe RBD behaviors will be estimated. For
treatment comparisons of change in efficacy endpoints of interest
across more than two timepoints (ie, each week of the trial),
statistical significance of between-group differences throughout
the entire trial will be estimated using repeated-measures
mixed-effects models that include treatment as a between-subjects
fixed effect, week as a repeated-measures fixed effect, the
interaction of treatment and week as a fixed-effect, subject as a
random effect, and background treatment of melatonin/clonazepam as
a covariate. Models that include treatment arm as a fixed effect
and both baseline value of the efficacy endpoint and background
treatment of melatonin/clonazepam as covariates. The least squares
means and standard errors for values of each treatment arm at each
week, p-values for omnibus tests of fixed effects, the magnitude of
least square mean differences and 95% CIs for differences in means
between treatment arms at each week, and p-values (adjusted for
multiplicity) for post-hoc tests of pairwise comparisons across
treatment arms and weeks will be estimated from these models for
the following efficacy endpoints: The number of nights with one or
more injury behaviors per week, based on self or caregiver reports
from the RBD daily diary, The number of nights with one or more
dramatic dreams per week, based on self or caregiver reports from
the RBD daily diary, The total count of physical activity, based on
assessment from the ActiGraph wGT3X-BT activity monitor worn in a
controlled in-home environment.
[0447] Safety Analyses: The safety analyses will be based on the
Safety Population. Safety will be assessed by summarizing and
analyzing AEs, laboratory analytes, vital signs, ECG parameters,
physical examination findings, and concomitant medications.
[0448] Adverse Events: AE verbatim text will be coded and
classified by body system and preferred (coded) term using the
Medical Dictionary for Regulatory Activities (MedDRA). AEs will be
assigned to the treatment based on the last dose received. All AEs
will be listed. AEs, Drug related AEs, SAEs, AEs that lead to
discontinuation of investigational product will be summarized by
treatment group. AEs will be summarized separately for the
Single-Blind Run-In Period and the Double-Blind Treatment Period.
Clinical Laboratory Tests: Summaries of clinical laboratory data
will be provided for subjects in the Safety Population. No
inferential statistics will be provided. Quantitative values and
change from baseline in quantitative values will be summarized by
planned nominal time and treatment for each quantitative laboratory
value. Listings of all laboratory results and reference ranges will
be provided. For multiple lab assessments at the same time point,
the worst value will be used for the data summaries. Laboratory
values that fall outside of the reference range will be flagged as
H=High or L=low. A lab shift table may be provided to show the
baseline to the worst post value. Laboratory values that do not
meet the laboratory abnormalities will be assigned N=normal in the
shift table.
[0449] Vital Signs, Electrocardiograms, Physical Findings, and
Other Safety Evaluations: Descriptive summaries of medical history,
vital signs, weight, and ECG parameters will be presented
separately for each study visit and treatment group. Clinically
significant abnormal morphological ECG findings will be summarized
by study visit. Abnormal physical examination findings will be
summarized to include the number and percentage of subjects
experiencing each treatment-emergent abnormal physical finding.
These data will be summarized by treatment group.
[0450] Suicidal ideation and behavior (C-SSRS): Descriptive
summaries of scores on the C-SSRS will be presented separately for
each study visit and treatment group. Scores will consist of three
composite values: suicidal ideations, suicidal behaviors, and
suicidal ideations or behaviors. Each value will be binary:
subjects answering `yes` to one or more of the ideation items
(items 1-5) will be classified as having suicidal ideations;
subjects answering `yes` to one or more of the behavior items
(items 6-10) will be classified as having suicidal ideations; and
subjects answering `yes` to one or more of either set of items
(items 1-10) will be classified as having suicidal ideations or
behaviors.
[0451] Parkinsonism (UPDRS II and III): Descriptive summaries of
scores on the UPDRS II, the UPDRS III, and a composite for the
UPDRS II and III will be presented separately for each study visit
and treatment group. For treatment comparisons of change in UPDRS
II, UPDRS III, and UPDRS II and III composite scores, statistical
significance of treatment group differences in change in values
from baseline to end of treatment visits will be estimated using
univariate ANCOVA models that include treatment arm as a fixed
effect and both baseline value of UPDRS score and background
treatment of melatonin/clonazepam as covariates. The least squares
means and standard errors for change in values from baseline to end
of treatment, the magnitude of least square mean differences and
95% CIs for differences in means between treatment arms, and
p-values for the test of the fixed effect of treatment will be
estimated from these models for each of these three measures. For
each treatment group, mean change in UPDRS II and III composite
scores from baseline to the end of treatment will be compared to
the established threshold for minimal clinically important change
of five points (Cummings 2014). Further, the proportion of subjects
in each treatment arm with an increase in UPDRS II and III
composite scores from baseline to end of treatment of at least 5
points will be calculated and compared using Fisher's exact
test.
[0452] MMSE: Descriptive summaries of scores on the MMSE will be
presented separately for each study visit and treatment group. For
treatment comparisons of change in MMSE scores, statistical
significance of treatment group differences in change in values
from baseline to end of treatment visits will be estimated using a
univariate ANCOVA model that includes treatment arm as a fixed
effect and both baseline value of the MMSE score and background
treatment of melatonin/clonazepam as covariates. The least squares
means and standard errors for change in values from baseline to end
of treatment, the magnitude of least square mean differences and
95% CIs for differences in means between treatment arms, and
p-values for the test of the fixed effect of treatment will be
estimated from this model.
[0453] MOCA: Descriptive summaries of scores on the MOCA will be
presented separately for each study visit and treatment group. For
treatment comparisons of change in MOCA scores, statistical
significance of treatment group differences in change in values
from baseline to end of treatment visits will be estimated using a
univariate ANCOVA model that includes treatment arm as a fixed
effect and both baseline value of the MOCA score and background
treatment of melatonin/clonazepam as covariates. The least squares
means and standard errors for change in values from baseline to end
of treatment, the magnitude of least square mean differences and
95% CIs for differences in means between treatment arms, and
p-values for the test of the fixed effect of treatment will be
estimated from this model.
[0454] Pharmacokinetic/Pharmacodynamic (PK/PD) Analyses: Plasma
nelotanserin and M1 metabolite concentrations will be listed and
summarized by Visit. Exploratory PK/PD analysis will include a
scatter plot of plasma nelotanserin and M1 concentrations collected
at Visit 5 (Day 29) versus the change in nightly frequency of RBD
behaviors from baseline to the end of treatment (primary efficacy
endpoint). Additional analyses (if any) will be specified in the
SAP.
[0455] Other Analyses: Additional analyses of the data may be
conducted as deemed appropriate and will be detailed in the SAP.
Further analyses of the data not specified in the SAP may be
undertaken as post hoc analyses after completion of the study.
Results of all study assessments will be included in an appendix to
the study report.
