is a C.sub.1-C.sub.12 alkyl and R.sup.f is H or a C.sub.1-C.sub.12
alkyl. In some embodiments the compound is of the formula (V) where
R.sup.1 is --C(O)NR.sup.eR.sup.f and R is a C.sub.1-C.sub.12 alkyl
and R.sup.f is C.sub.1-C.sub.12 alkyl. In some embodiments the
compound is of the formula (V) where R.sup.1 is
--C(O)NR.sup.eR.sup.f and R.sup.e and R.sup.f are taken together
with the N to which they are attached to form a heterocyclic ring.
In some embodiments R.sup.e is a C.sub.1-C.sub.12 alkyl and R.sup.f
is H. For example, R.sup.e in some embodiments is methyl, ethyl,
propyl, butyl, pentyl or hexyl and R.sup.f is H. In another
particular embodiment R.sup.e is a C.sub.3-C.sub.12 cycloalkyl
(e.g., cyclopentyl) and R.sup.f is H. In some embodiments R.sup.e
is a C.sub.3-C.sub.12 branched alkyl (e.g., tert-butyl) and R.sup.f
is H. In some embodiments R.sup.e is a C.sub.1-C.sub.8 alkyl and
R.sup.f is H (e.g., where R.sup.e is methyl and R.sup.f is H). In
some embodiments R.sup.e is a C.sub.3-C.sub.6 alkyl and R.sup.f is
H (e.g., where R.sup.e is propyl or butyl and R.sup.f is H). In
another particular embodiment R.sup.e is a C.sub.1-C.sub.12 alkyl
and R.sup.f is a C.sub.1-C.sub.12 alkyl (e.g., where R.sup.e is
ethyl and R.sup.f is methyl). Compounds of formula (V) are also
provided where R.sup.e and R.sup.f are independently a
C.sub.1-C.sub.12 alkyl (e.g., where both R.sup.e and R.sup.f are
methyl). In some embodiments the compounds of formula (V) are
provided where R.sup.e and R.sup.f are independently a
C.sub.1-C.sub.12 alkyl. In some embodiments R.sup.e and R.sup.f are
the same C.sub.1-C.sub.12 alkyl, e.g., when both R.sup.e and
R.sup.f are ethyl. In some embodiments R.sup.e and R.sup.f are
independently a C.sub.1-C.sub.8 alkyl. In some embodiments R.sup.e
and R.sup.f are independently a C.sub.3-C.sub.6 alkyl. In some
embodiments at least one of R.sup.e and R.sup.f is a
C.sub.3-C.sub.6 cycloalkyl. In still some embodiments R.sup.e and
R.sup.f are taken together with the N to which they are attached to
form a heterocyclic ring. In some embodiments when R.sup.e and
R.sup.f are taken together to form a heterocyclic ring, the ring is
a 4- to 7-membered heterocyclic ring. The heterocyclic ring formed
by R.sup.e, R.sup.f and the N to which they are attached in some
embodiments contains only C and N as annular atoms. In some
embodiments the heterocycle contains as annular atoms only C and
the N provided when R.sup.e and R.sup.f are taken together with the
N to which they are attached. In a particular, R.sup.e and R.sup.f
are taken together with the N to which they are attached to form a
pyrrolidinyl or piperidinyl ring. In some embodiments R.sup.1
is:

[0275] In some embodiments a compound of Formula VI is:
##STR00215##
8. Salts
[0276] Salts of compounds described above can be used in the
disclosed methods. If a compound has, for example, at least one
basic center, it can form an acid addition salt. These are formed,
for example, with strong inorganic acids, such as mineral acids,
for example sulfuric acid, phosphoric acid or a hydrohalic acid,
with strong organic carboxylic acids, such as alkanecarboxylic
acids of 1 to 4 carbon atoms which are unsubstituted or
substituted, for example, by halogen, for example acetic acid, such
as saturated or unsaturated dicarboxylic acids, for example oxalic,
malonic, succinic, maleic, fumaric, phthalic or terephthalic acid,
such as hydroxycarboxylic acids, for example ascorbic, glycolic,
lactic, malic, tartaric or citric acid, such as amino acids, (for
example aspartic or glutamic acid or lysine or arginine), or
benzoic acid, or with organic sulfonic acids, such as
(C.sub.1-C.sub.4) alkyl or arylsulfonic acids which are
unsubstituted or substituted, for example by halogen, for example
methyl- or p-toluene-sulfonic acid. Corresponding acid addition
salts can also be formed having, if desired, an additionally
present basic center. Compounds having at least one acid group (for
example COOH) can also form salts with bases. Suitable salts with
bases are, for example, metal salts, such as alkali metal or
alkaline earth metal salts, for example sodium, potassium or
magnesium salts, or salts with ammonia or an organic amine, such as
morpholine, thiomorpholine, piperidine, pyrrolidine, a mono, di or
tri-lower alkylamine, for example ethyl, tert-butyl, diethyl,
diisopropyl, triethyl, tributyl or dimethyl-propylamine, or a mono,
di or trihydroxy lower alkylamine, for example mono, di or
triethanolamine. Corresponding internal salts can furthermore be
formed. Salts which are unsuitable for pharmaceutical uses but
which can be employed, for example, for the isolation or
purification of free compounds or their pharmaceutically acceptable
salts, are also included. In some embodiments salts of compounds
which contain a basic group include monohydrochloride,
hydrogensulfate, methanesulfonate, phosphate or nitrate. In some
embodiments salts of compounds which contain an acid group include
sodium, potassium and magnesium salts and pharmaceutically
acceptable organic amines.
[0277] In some embodiments the salts are pharmaceutically
acceptable (e.g., non-toxic, physiologically acceptable) salts.
Pharmaceutically acceptable salts retain at least some of the
biological activity of the free (non-salt) compound and which can
be administered as drugs or pharmaceuticals to an individual. Such
salts, for example, include: (1) acid addition salts, formed with
inorganic acids such as hydrochloric acid, hydrobromic acid,
sulfuric acid, nitric acid, phosphoric acid, and the like; or
formed with organic acids such as acetic acid, oxalic acid,
propionic acid, succinic acid, maleic acid, tartaric acid and the
like; (2) salts formed when an acidic proton present in the parent
compound either is replaced by a metal ion, e.g., an alkali metal
ion, an alkaline earth ion, or an aluminum ion; or coordinates with
an organic base. Acceptable organic bases include ethanolamine,
diethanolamine, triethanolamine and the like. Acceptable inorganic
bases include aluminum hydroxide, calcium hydroxide, potassium
hydroxide, sodium carbonate, sodium hydroxide, and the like.
Further examples of pharmaceutically acceptable salts include those
listed in Berge et al., Pharmaceutical Salts, J. Pharm. Sci. 1977
January; 66(1):1-19. Pharmaceutically acceptable salts can be
prepared in situ in the manufacturing process, or by separately
reacting a purified compound in its free acid or base form with a
suitable organic or inorganic base or acid, respectively, and
isolating the salt thus formed during subsequent purification. It
should be understood that a reference to a pharmaceutically
acceptable salt includes the solvent addition forms or crystal
forms thereof, particularly solvates or polymorphs. Solvates
contain either stoichiometric or non-stoichiometric amounts of a
solvent, and are often formed during the process of
crystallization. Hydrates are formed when the solvent is water, or
alcoholates are formed when the solvent is alcohol. Polymorphs
include the different crystal packing arrangements of the same
elemental composition of a compound. Polymorphs usually have
different X-ray diffraction patterns, infrared spectra, melting
points, density, hardness, crystal shape, optical and electrical
properties, stability, and solubility. Various factors such as the
recrystallization solvent, rate of crystallization, and storage
temperature may cause a single crystal form to dominate.
[0278] Therapeutic Methods
[0279] In addition to the breast cancer indications discussed below
and the therapeutic indications disclosed in U.S. Pat. No.
7,709,517; US 2011/0003839; WO 2010/118354; WO 2011/044327; and WO
2010/099238, compounds of Formulae (I), (II), (III), (IV), (V), and
(VI) can be used to treat androgen receptor related diseases or
conditions such as benign prostate hyperplasia, hair loss, and
acne. These and related compounds may also be useful as modulators
of other nuclear receptors, such as glucocorticoid receptor,
estrogen receptor, and peroxisome proliferator-activated receptor,
and as therapeutic agents for diseases in which nuclear receptors
play a role, such as breast cancer, ovarian cancer, diabetes,
cardiac diseases, and metabolism related diseases.
[0280] "Treating" or "treatment" as used herein is an approach for
obtaining a beneficial or desired result, including, but not
limited to, relief from a symptom, lessening of a symptom, and
preventing a worsening of a symptom associated with the disease
being treated. Treatment also includes, but is not limited to, any
one or more of enhancing survival time, enhancing progression-free
survival time, and reducing tumor size.
[0281] 1. Breast Cancers
[0282] Compounds can be used to treat various forms of breast
cancer, whether or not the breast cancers express androgen
receptors or estrogen receptors. Breast cancers that can be treated
include, but are not limited to, basal-like breast cancer,
BRCA1-related breast cancer, medullary breast cancer, metaplastic
breast cancer, special histologic type of breast cancer, triple
negative breast cancer, and breast cancer resistant to endocrine
therapy.
[0283] In some embodiment, patients to be treated are
post-menopausal. In other embodiments patients to be treated are
pre-menopausal. In other embodiments patients to be treated are
peri-menopausal. In some embodiments patients to be treated are
men.
[0284] In some embodiments breast cancers are ER+(i.e., 1% or more
of the cells tested express ER detectable by immunocytochemistry).
In some embodiments, breast cancers contain cells that demonstrate
estradiol-mediated growth. In some embodiments patients to be
treated have no detectable circulating levels of estradiol. In some
embodiments patients to be treated have circulating levels of
estradiol greater than 10 pmol/L. In some embodiments patients to
be treated have circulating levels of estradiol less than 10
pmol/L. In some embodiments estradiol levels are measured by a
double-antibody procedure as described in Cummings et al., JAMA
287, 216-20, 2002.
[0285] i. Triple Negative Breast Cancer
[0286] In some of embodiments the breast cancer is a triple
negative breast cancer including, but not limited to, subtypes of
triple negative breast cancer such as of basal-like type 1 (BLi),
basal-like type 2 (BL2), immunomodulatory (IM), mesenchymal (M),
mesenchymal stem-like (MSL), and luminal androgen receptor (LAR)
subtypes. "Triple negative breast cancer" as used herein is
characterized by lack of estrogen receptor (ER), progesterone
receptor (PR), and lack of overexpression or amplification of
Her2neu. A tumor is negative for expression of ER or PR if fewer
than 1% of the cells tested are positive for ER or PR, as measured
by immunohistochemistry, and if the Her2 gene is not expressed (for
example, amplification is not detected by FISH). Triple negative
breast cancer is clinically characterized as more aggressive and
less responsive to standard treatment and is associated with poorer
overall patient prognosis. It is diagnosed more frequently in
younger women and in women with BRCA1 mutations.
[0287] In some embodiments a triple negative breast cancer is AR+;
i.e., it contains cells that express detectable androgen receptors
as detected by immunohistochemistry, ligand binding, or other
methods known in the art. In other embodiments a triple negative
breast cancer is AR-.
[0288] ii. ER+ Breast Cancer Resistant to Endocrine Therapy
[0289] Approximately 75% of breast cancers express the estrogen
receptor (ER) and are candidates for endocrine therapy. The
selective ER modulator tamoxifen is the most commonly prescribed
endocrine therapy; however, approximately 30 percent of tumors that
retain estrogen (ER) do not respond to estrogen/ER directed
therapies such as tamoxifen or aromatase inhibitors (AI) and nearly
all patients with metastatic disease develop resistance. In such
patients, a compound can provide a therapeutic intervention.
[0290] In some embodiments the breast cancer is ER+, i.e., it
contains detectable levels of estrogen receptor, measured as
described above, but is resistant to endocrine therapy. "Endocrine
therapy" as used herein includes administration of one or more
aromatase inhibitors (e.g., anastrozole, exemestane, letrozole)
and/or administration of one or more estrogen receptor modulators
(e.g., tamoxifen, raloxifen, fulvestrant). "Resistant to endocrine
therapy" as used herein means that the tumors (primary or
metastases) do not respond to one or more of the above treatments
by shrinking, but rather remains the same size or increases in
size, or that recur in response to such treatment at any time in
the patient's livespan.
[0291] In some embodiments the breast cancer is ER+/AR+. In some
embodiments the breast cancer is ER+/AR-. In some embodiments the
breast cancer contains cells that are progesterone receptor
positive (PR+) as detected by immunohistochemistry or ligand
binding assays or any other method of detection. In some
embodiments the breast cancer contains no detectable cells with
progesterone receptors; e.g., the breast cancer is progesterone
receptor negative (PR-). In some embodiments a breast cancer
contains cells that are Her2 positive (Her2+) as detected by
observable Her2 gene amplification after in situ hybridization. In
some embodiments a breast cancer contains no detectable cells with
amplification or expression or overexpression of Her2; e.g., the
breast cancer is Her2 negative (Her2-). The progesterone receptors
and Her2 can be present on the same or different populations of
cells, which may be the same or different as the populations of
cells expressing ER and/or AR.
[0292] In some embodiments abreast cancer is identified as AR+,
ER+, and Her2+. In some embodiments a breast cancer is identified
as AR+, ER+, and PR+. In some embodiments a breast cancer is
identified as AR+, ER+, Her2+, and PR+. In some embodiments a
breast cancer is identified as AR-, ER+, and Her2+. In some
embodiments a breast cancer is identified as AR-, ER+, and PR+. In
some embodiments a breast cancer is identified as AR-, ER+, Her2+,
and PR+. In some embodiments, a breast cancer is identified as AR+,
ER-, HER2+, PR-.
[0293] 2. Pharmaceutical Compositions
[0294] Compounds can be formulated in any type of pharmaceutical
composition known in the art, including, but not limited to,
tablets, troches, pills, capsules, syrups, elixirs, injectable
solutions, and the like.
[0295] A pharmaceutical composition typically includes a
pharmaceutically or pharmacologically acceptable excipient or
carrier. As used herein, by "pharmaceutically acceptable" or
"pharmacologically acceptable" is meant a material that is not
biologically or otherwise undesirable, e.g., the material may be
incorporated into a pharmaceutical composition administered to a
patient without causing any significant undesirable biological
effects or interacting in a deleterious manner with any of the
other components of the composition in which it is contained. In
some embodiments pharmaceutically acceptable carriers or excipients
have met the required standards of toxicological and manufacturing
testing and/or are included on the Inactive Ingredient Guide
prepared by the U.S. Food and Drug administration.
[0296] The term "excipient" as used herein means an inert or
inactive substance that may be used in the production of a drug or
pharmaceutical, such as a tablet containing a compound as an active
ingredient. Various substances may be embraced by the term
excipient, including without limitation any substance used as a
binder, disintegrant, coating, compression/encapsulation aid, cream
or lotion, lubricant, solutions for parenteral administration,
materials for chewable tablets, sweetener or flavoring,
suspending/gelling agent, or wet granulation agent. Binders
include, e.g., carbomers, povidone, xanthan gum, etc.; coatings
include, e.g., cellulose acetate phthalate, ethylcellulose, gellan
gum, maltodextrin, enteric coatings, etc.;
compression/encapsulation aids include, e.g., calcium carbonate,
dextrose, fructose d (dc="directly compressible"), honey dc,
lactose (anhydrate or monohydrate; optionally in combination with
aspartame, cellulose, or microcrystalline cellulose), starch dc,
sucrose, etc.; disintegrants include, e.g., croscarmellose sodium,
gellan gum, sodium starch glycolate, etc.; creams or lotions
include, e.g., maltodextrin, carrageenans, etc.; lubricants
include, e.g., magnesium stearate, stearic acid, sodium stearyl
fumarate, etc.; materials for chewable tablets include, e.g.,
dextrose, fructose dc, lactose (monohydrate, optionally in
combination with aspartame or cellulose), etc.; suspending/gelling
agents include, e.g., carrageenan, sodium starch glycolate, xanthan
gum, etc.; sweeteners include, e.g., aspartame, dextrose, fructose
dc, sorbitol, sucrose dc, etc.; and wet granulation agents include,
e.g., calcium carbonate, maltodextrin, microcrystalline cellulose,
etc.
[0297] Tablets, troches, pills, capsules, and the like can also
contain the following: binders such as gum tragacanth, acacia, corn
starch or gelatin; excipients such as dicalcium phosphate; a
disintegrating agent such as corn starch, potato starch, alginic
acid and the like; a lubricant such as magnesium stearate; and a
sweetening agent such as sucrose, fructose, lactose or aspartame or
a flavoring agent such as peppermint, oil of wintergreen, or cherry
flavoring can be added. When the unit dosage form is a capsule, it
can contain, in addition to materials of the above type, a liquid
carrier, such as a vegetable oil or a polyethylene glycol. Various
other materials can be present as coatings or to otherwise modify
the physical form of the solid unit dosage form. For instance,
tablets, pills, or capsules can be coated with gelatin, wax,
shellac or sugar and the like. A syrup or elixir can contain the
active compound, sucrose or fructose as a sweetening agent, methyl
and propylparabens as preservatives, a dye and flavoring such as
cherry or orange flavor. Of course, any material used in preparing
any unit dosage form should be pharmaceutically acceptable and
substantially non-toxic in the amounts employed. In addition, a
diarylhydantoin compound can be incorporated into sustained-release
preparations and devices. For example, a compound can be
incorporated into time release capsules, time release tablets, and
time release pills.
[0298] Pharmaceutical dosage forms suitable for injection or
infusion can include sterile aqueous solutions or dispersions or
sterile powders comprising a compound which are adapted for the
extemporaneous preparation of sterile injectable or infusible
solutions or dispersions, optionally encapsulated in liposomes. The
ultimate dosage form typically is sterile, fluid, and stable under
the conditions of manufacture and storage. The liquid carrier or
vehicle can be a solvent or liquid dispersion medium comprising,
for example, water, ethanol, a polyol (for example, glycerol,
propylene glycol, liquid polyethylene glycols, and the like),
vegetable oils, nontoxic glyceryl esters, and suitable mixtures
thereof. The proper fluidity can be maintained, for example, by the
formation of liposomes, by the maintenance of the required particle
size in the case of dispersions or by the use of surfactants. The
prevention of the action of microorganisms can be brought about by
various antibacterial and antifungal agents, for example, parabens,
chlorobutanol, phenol, sorbic acid, thimerosal, and the like. In
many cases, isotonic agents are included, for example, sugars,
buffers or sodium chloride. Prolonged absorption of the injectable
compositions can be brought about by the use in the compositions of
agents delaying absorption, for example, aluminum monostearate and
gelatin.
[0299] Sterile injectable solutions are prepared by incorporating a
compound in the required amount in the appropriate solvent with
various of the other ingredients enumerated above, as required,
followed by filter sterilization. In the case of sterile powders
for the preparation of sterile injectable solutions, methods of
preparation include vacuum drying and freeze drying techniques,
which yield a powder of the active ingredient plus any additional
desired ingredient present in the previously sterile-filtered
solutions.
[0300] Useful solid carriers include finely divided solids such as
talc, clay, microcrystalline cellulose, silica, alumina and the
like. Other solid carriers include nontoxic polymeric nanoparticles
or microparticles. Useful liquid carriers include water, alcohols
or glycols or water/alcohol/glycol blends, in which a compound can
be dissolved or dispersed at effective levels, optionally with the
aid of non-toxic surfactants. Adjuvants such as fragrances and
additional antimicrobial agents can be added to optimize the
properties for a given use. The resultant liquid compositions can
be applied from absorbent pads, used to impregnate bandages and
other dressings, or sprayed onto the affected area using pump-type
or aerosol sprayers.
[0301] Thickeners such as synthetic polymers, fatty acids, fatty
acid salts and esters, fatty alcohols, modified celluloses or
modified mineral materials can also be employed with liquid
carriers to form spreadable pastes, gels, ointments, soaps, and the
like, for application directly to the skin of the user.
[0302] Examples of useful dermatological compositions which can be
used to deliver a compound to the skin are known to the art; for
example, see Jacquet et al. (U.S. Pat. No. 4,608,392), Geria (U.S.
Pat. No. 4,992,478), Smith et al. (U.S. Pat. No. 4,559,157) and
Wortzman (U.S. Pat. No. 4,820,508).
[0303] In some embodiments the pharmaceutical composition is a unit
dosage form. As used herein, "unit dosage form" is a physically
discrete unit containing a predetermined quantity of active.
[0304] 3. Dosages
[0305] As used herein, the term "effective amount" intends such
amount of a compound which in combination with its parameters of
efficacy and toxicity, as well as based on the knowledge of the
practicing specialist should be effective in a given therapeutic
form. As is understood in the art, an effective amount may be in
one or more doses, i.e., a single dose or multiple doses may be
required to achieve the desired treatment endpoint. An effective
amount may be considered in the context of administering one or
more therapeutic agents, and a single agent may be considered to be
given in an effective amount if, in conjunction with one or more
other agents, a desirable or beneficial result may be or is
achieved. Suitable doses of any of the co-administered compounds
may optionally be lowered due to the combined action (e.g.,
additive or synergistic effects) of the compounds.
[0306] Useful dosages of compounds can be determined by comparing
their in vitro activity and/or in vivo activity in animal models.
Methods for the extrapolation of effective dosages in mice, and
other animals, to humans are known to the art; for example, see
U.S. Pat. No. 4,938,949. For example, the concentration of a
compound in a liquid composition, such as a lotion, can be from
about 0.1-25% by weight, or from about 0.5-10% by weight. The
concentration in a semi-solid or solid composition such as a gel or
a powder can be about 0.1-5% by weight, or about 0.5-2.5% by
weight.
[0307] The amount of a compound 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 be ultimately at
the discretion of the attendant physician or clinician.
[0308] Effective dosages and routes of administration of compounds
are conventional. The exact amount (effective dose) of the agent
will vary from subject to subject, depending on, for example, the
species, age, weight and general or clinical condition of the
subject, the severity or mechanism of any disorder being treated,
the particular agent or vehicle used, the method and scheduling of
administration, and the like. A therapeutically effective dose can
be determined empirically, by conventional procedures known to
those of skill in the art. See, e.g., The Pharmacological Basis of
Therapeutics, Goodman and Gilman, eds., Macmillan Publishing Co.,
New York. For example, an effective dose can be estimated initially
either in cell culture assays or in suitable animal models. The
animal model can also be used to determine the appropriate
concentration ranges and routes of administration. Such information
can then be used to determine useful doses and routes for
administration in humans. A therapeutic dose can also be selected
by analogy to dosages for comparable therapeutic agents.
[0309] The particular mode of administration and the dosage regimen
will be selected by the attending clinician, taking into account
the particulars of the case (e.g., the subject, the disease, the
disease state involved, and whether the treatment is prophylactic).
Treatment can involve daily or multi-daily doses of compound(s)
over a period of a few days to months, or even years.
[0310] In general, however, a suitable dose will be in the range of
from about 0.001 to about 100 mg/kg, e.g., from about 0.01 to about
100 mg/kg of body weight per day, such as above about 0.1 mg per
kilogram, or in a range of from about 1 to about 10 mg per kilogram
body weight of the recipient per day. For example, a suitable dose
can be about 1 mg/kg, 10 mg/kg, or 50 mg/kg of body weight per
day.
[0311] A compound is conveniently administered in unit dosage form;
for example, containing 0.05 to 10000 mg, 0.5 to 10000 mg, 5 to
1000 mg, or about 100 mg of active ingredient per unit dosage
form.
[0312] A compound can be administered to achieve peak plasma
concentrations of, for example, from about 0.5 to about 75 M, about
1 to 50 M, about 2 to about 30 M, or about 5 to about 25 M.
Exemplary desirable plasma concentrations include at least or no
more than 0.25, 0.5, 1, 5, 10, 25, 50, 75, 100 or 200 M. For
example, plasma levels can be from about 1 to 100 micromolar or
from about 10 to about 25 micromolar. This can be achieved, for
example, by the intravenous injection of a 0.05 to 5% solution of a
diarylhydantoin or hydantoin compound, optionally in saline, or
orally administered as a bolus containing about 1-100 mg of a
diarylhydantoin or hydantoin compound. Desirable blood levels can
be maintained by continuous infusion to provide about 0.00005-5 mg
per kg body weight per hour, for example at least or no more than
0.00005, 0.0005, 0.005, 0.05, 0.5, or 5 mg/kg/hr. Alternatively,
such levels can be obtained by intermittent infusions containing
about 0.0002-20 mg per kg body weight, for example, at least or no
more than 0.0002, 0.002, 0.02, 0.2, 2, 20, or 50 mg of a compound
per kg of body weight.
[0313] A compound can 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 can be further divided, e.g., into a number of
discrete loosely spaced administrations; such as multiple
inhalations from an insufflator.
[0314] 4. Methods of Administration
[0315] A compound can be administered using pharmaceutical
compositions comprising a therapeutically effective amount of the
compound and a pharmaceutically acceptable carrier or diluent, in a
variety of forms adapted to the chosen route of administration, for
example, orally, nasally, intraperitoneally, or parenterally, by
intravenous, intramuscular, topical or subcutaneous routes, or by
injection into tissue.
[0316] A compound can be systemically administered, e.g., orally,
in combination with a pharmaceutically acceptable vehicle such as
an inert diluent or an assimilable edible carrier; or by inhalation
or insufflation. It can be enclosed in hard or soft shell gelatin
capsule, can be compressed into a tablet, or can be incorporated
directly with the food of a patient's diet. For oral therapeutic
administration, a compound can be combined with one or more
excipients and used in the form of an ingestible tablet, a buccal
tablet, troche, capsule, elixir, suspension, syrup, wafer, and the
like. A compound can be combined with a fine inert powdered carrier
and inhaled by the subject or insufflated. In some embodiments such
compositions and preparations contain at least 0.1% diarylhydantoin
or hydantoin compound. The percentage of the compositions and
preparations can, of course, be varied and can conveniently be
between about 2% to about 60% of the weight of a given unit dosage
form. The amount of diarylhydantoin or hydantoin compound in such
therapeutically useful compositions is such that an effective
dosage level will be obtained.
[0317] A compound can also be administered intravenously or
intraperitoneally by infusion or injection. Solutions of a compound
can be prepared in water, optionally mixed with a nontoxic
surfactant. Dispersions can also be prepared in glycerol, liquid
polyethylene glycols, triacetin, and mixtures thereof and in oils.
Under ordinary conditions of storage and use, these preparations
can contain a preservative to prevent the growth of
microorganisms.
[0318] 5. Combination Therapies
[0319] In some embodiments combinations of one or more compounds
are used. A "combination" compounds includes one or more compounds
administered substantially simultaneously, whether or not in the
same pharmaceutical composition, or sequentially. compounds can,
but need not be, chemically similar (e.g., two diarylhydantoin
compounds; a diarylhydantoin compound and a diarylthiohydantoin,
etc.).

Example 1
[0366] RD162' Blocks DHT-Mediated Proliferation in MCF7 Cells
[0367] MCF7 cells are commonly used luminal breast cancer cells
that express high levels of ER and some AR. MCF7 cells were plated
in phenol red-free medium containing charcoal stripped serum. The
next day, cells were treated with vehicle alone (ethanol, EtOH), 10
nM dihydrotestosterone (DHT), 10 .mu.M RD162' (RD162'), or a
combination of DHT+RD162'. An in vitro proliferation assay using
the tetrazolium salt MTT was performed at various time points. The
values were normalized to an untreated plate read 24 hours after
plating to account for differences in cell density. The results are
shown in FIG. 1. These experiments demonstrated that RD162' blocks
DHT-mediated growth of MCF7 cells.
Example 2
[0368] RD162' Blocks DHT-Mediated Growth in BCK4 Cells
[0369] BCK4 cells are breast cancer cells that express more AR than
ER and respond better to androgens than to estrogens. Proliferation
of BCK4 cells was assayed as described above in the presence of DHT
and in the presence of RD162' and DHT. The results are shown in
FIG. 2. These experiments demonstrated that RD162' blocks
DHT-mediated growth of BCK4 cells.
Example 3
[0370] RD162' Blocks Estradiol-Mediated Growth in MCF7 Cells
[0371] MCF7 cells were plated in phenol red-free medium containing
charcoal stripped serum. The next day, cells were treated with
vehicle alone (EtOH), 10 nM estradiol (E2), 10 .mu.M RD162', or a
combination of E2 and RD162'. An MTT assay was performed at various
time points. The values were normalized to an untreated plate read
24 hours after plating to account for differences in cell density.
The results are shown in FIG. 3. This experiment demonstrates that
RD162' blocks estradiol-mediated growth of MCF7 cells.
Example 4
[0372] RD162' Blocks E2-Mediated Upregulation of SDF-1 and
Progesterone Receptor Gene Expression
[0373] Expression of SDF-1, a gene involved in estrogen mediated
proliferation, and the progesterone receptor gene (a known estrogen
regulated gene and marker of ER.alpha. activity, were assayed in
the presence or absence of estradiol (E2). RD162' blocks
E2-mediated upregulation of these E2/ER regulated genes, indicating
that RD162' modulates ER.alpha. activity, as shown in FIG. 4.
Example 5
[0374] In Vivo Studies Demonstrating that RD162' Inhibits
DHT-Mediated Growth in MCF7 Cells Grown in the Mammary Glands of
Nod-Scid Mice.
[0375] MCF7 cells (1.times.10.sup.6 cells) engineered to express
luciferase were mixed with 100 of matrigel and injected into the
mammary fat pad of 6-8 week old ovariectomized nod/scid mice. Two
tumors were implanted per mouse, one on each side. The mice had a
DHT pellet implanted subcutaneously at the time of injection of
tumor cells. Tumor burden was measured by either caliper or whole
body in vivo luminescent (IVIS) imaging. At day 22, mice were
matched based on tumor burden measured by IVIS imaging and
separated into two groups. One group received a control chow and
the other received chow containing 50 mg/kg RD162'. The results are
shown in FIGS. 5A-D. FIGS. 5A-B depict tumor growth over time.
FIGS. 5C-D show individual tumor size at the end of the study.
Example 6
[0376] RD162' Blocks Proliferation of Triple Negative Breast Cancer
Cells
[0377] A Western blot of four luminal (ER+, PR+) and four triple
negative (ER-,PR-, Her2-) breast cancer cell lines for androgen
receptor, estrogen receptor and tubulin (as a loading control) was
prepared (FIG. 6A). Three of the triple negative cell lines have
robust AR expression.
[0378] MDA468 and BT20 cells were plated in phenol red-free medium
containing charcoal stripped serum. The next day, cells were
treated with vehicle alone (EtOH), 10 nM dihydrotestosterone (DHT),
10 .mu.M RD162', or a combination of DHT and RD162'. An MTT assay
was performed at various time points. The values were normalized to
an untreated plate read 24 hours after plating to account for
differences in cell density. The results are shown in FIGS. 6B-C.
This experiment demonstrates that RD162' blocks growth of triple
negative breast cancer cells.
Example 7
[0379] RD162' Inhibits DHT-Induced Proliferation in Apocrine Breast
Cancer Cells (AR+, ER-, HER2+, PR-) and Inhibits the In Vivo Growth
of these Cells in a Xenograft Model in Mammary Glands of NOD SCID
Mice.
[0380] The effect of RD162' on DHT-induced proliferation of
apocrine breast cancer cells was assessed in MDA-MB-453 cells,
which are AR+, ER-, HER2+, and PR-, using a colorimetric in vitro
proliferation assay using the tetrazolium salt MTS ("MTS assay")
and a luciferase assay. The results of the MTS assay are shown in
FIG. 7A. These results indicate that 10 .mu.M RD162' inhibits
proliferation induced by 10 nM DHT.
[0381] A luciferase assay carried out with MDA-kb2 cells, which
were derived from MDA-MB-453 cells but contain an
androgen-dependent luciferase reporter, demonstrated that RD162'
inhibits proliferation induced by DHT in a dose dependent manner.
The results are shown in FIG. 7B. Error bars reflect the SEM of
independent experiments and * indicates P<0.05, ** indicates
P<0.01, *** indicates P<0.001 (ANOVA with Bonferroni's
multiple comparison test correction).
[0382] Immunocytochemical assays were carried out in MDA-kb2 cells
using an antibody to AR. Cells were treated for 3 hours with
vehicle (Vh), 1 nM DHT, 10 .mu.M RD162', or 10 .mu.M RD162' and
DHT. The graph shown in FIG. 7C displays the ratio of nuclear to
total AR for all cells measured. The results demonstrate that
RD162' inhibits nuclear translocation of AR induced by DHT.
[0383] In vivo growth of apocrine breast cancer cells was
investigated in a xenograft model in mammary glands of NOD SCID
mice. MDA-MB-453 cells (6.times.10.sup.6) were injected into the
4.sup.th inguinal mammary fat pad of NOD-SCID-IL2Rgc-/- female
mice. A 60-day release DHT pellet was implanted subcutaneously into
3 groups of mice at the time of cell injection. Tumor size was
measured using calipers and once the tumors reached 100 mm.sup.3,
the mice began receiving 10 mg/kg/d RD162', 25 mg/kg/d RD162' or
vehicle by oral gavage.
[0384] The results are shown in FIG. 7D and FIG. 7E. The results
demonstrate that RD162' at either dose inhibited tumor growth
induced by DHT (FIG. 7D). Tumors were weighed at necropsy and both
doses of RD162' significantly inhibited DHT induced tumor growth
(FIG. 7E). Error bars reflect the SEM and * indicates P<0.05,
*** indicates P<0.001 (Mann Whitney).
Example 8
[0385] RD162' Inhibits the Growth of Triple Negative Breast Cancer
Cells
[0386] Hs578T, a TNBC cell line, was plated in phenol red free
DMEM/F12 containing 5% DCC for 2 days before treated with vehicle
control, RD162' (10 .mu.M), DHT (10 nM), and RD162'+DHT for 9 days.
Viable cells were assayed by MTS assay. The results are shown in
FIG. 8. Averages of the triplicate data points are shown with
standard deviation. *** p<0.001 (two-tail t-test). Note that DHT
treatment does not increase the growth of Hs578T cells.
Example 9
[0387] RD162' Together with Herceptin Inhibits the Growth of Her2+
Breast Cancer Cells
[0388] SKBR3, a Her2+ breast cancer cell line, was grown in DMEM+1%
FBS in the presence of vehicle control, 10 .mu.M RD162', 20
.mu.g/ml of Herceptin, and RD162'+Herceptin respectively for 8 days
before analyzed for viable cells with MTS assay. The results are
shown in FIG. 9. Averages of the triplicate data points are shown
with standard deviation. *p<0.05 and ***p<0.001 (two-tail
t-test).
Example 10
[0389] RD162' Inhibits Androgen Stimulated Growth of MDA-MB-453
Tumors
[0390] MDA-MB-453 cells were injected orthotopically in the mammary
gland of female NOD-SCID-IL2Rgc-/- mice. Three groups had a DHT
pellet implanted SQ and one group had no pellet (Vehicle). Once the
tumors reached 100 mm.sup.3, the mice were given either RD162' (10
mg/kg) or vehicle (Vehicle and DHT groups) by daily oral gavage.
When the tumors reached 400 mm.sup.3, another group was given a
higher dose of RD162' (25 mg/kg) by oral gavage. The results are
shown in FIGS. 10A-D.
[0391] Tumor volume was measured weekly by caliper. Error bars
represent SEM. * indicates P<0.05, ** indicates P<0.01 for
DHT vs DHT+RD162' (10 mg/kg), Wilcoxon rank sum (FIG. 10A). There
were no significant differences at any time point for DHT vs
DHT+RD162' (25 mg/kg). Tumors were excised and weighed at the end
of the experiment (FIG. 10B). Tumor sections stained for cleaved
caspase 3 were quantified and representative images shown below
(200.times. magnification). For tumor weights and cleaved caspase 3
staining, * indicates P<0.05, ** indicates P<0.01, ***
indicates P<0.001, ANOVA with Bonferroni's multiple comparison
test correction (FIG. 10C). Nuclear AR staining was quantified and
representative images (400.times. magnification) are shown below. *
indicates P<0.05, *** indicates P<0.001, Kruskal-Wallis with
Dunn's multiple comparison test correction (FIG. 10D).
Example 11
[0392] RD162' is as Effective as Tamoxifen at Inhibiting Estrogen
Stimulated Tumor Growth.
[0393] MCF7-TGL cells stably expressing luciferase were implanted
orthotopically in the mammary gland of ovariectomized female nude
mice. All mice had an E2 pellet implanted SQ and were either given
control chow (E2), control chow plus a tamoxifen pellet implanted
SQ (E2+tam) or chow containing 50 mg/kg RD162' (E2+RD162'). The
beginning of treatment is indicated by an arrow. Tumor burden was
measured by whole body luminescence. The results are shown in FIGS.
11A-D. Mean total flux of all mice in each of the treatment groups
is shown. Mice were matched on day -3 and treatment began on day 0.
* indicates P<0.05, ANOVA with Bonferroni's multiple comparison
test correction (FIG. 11A). The total luminescent flux is shown for
all individual mice at the day of matching (Day -3) and at the
final imaging day (Day 11). * indicates P<0.05, ANOVA with
Bonferroni's multiple comparison test correction (FIG. 11B). Images
of luminescent signal in the two treatment groups at the day of
matching (day -2) and the final day of imaging (day 11) is shown
(FIG. 11C). Mice were injected with BrdU two hours prior to
sacrifice. Immunohistochemistry for BrdU was performed on tumor
sections and quantified using image J. Representative images of
BrdU staining (left, 400.times. magnification) and quantification
(right) shown are shown. ** indicates P<0.01 for E2 vs
E2+Tamoxifen, *** indicates P<0.001 for E2 vs E2+RD162', ANOVA
with Bonferroni's multiple comparison test correction (FIG.
11D).
