protein" encompasses all possible modifications known to the person
skilled in the art, e.g. chemical modification, deletion.
[0071] The term "naturally occurring" within the meaning of the
present invention refers to proteins or peptides found naturally in
mammal organism.
[0072] In one embodiment of the present invention, said protein is
selected from the group consisting of toxins, chondroitin, elastin,
actin, myosin, aprotinin, growth hormone, growth hormone releasing
factor, parathyroid hormone, thyroid stimulating hormone,
lipoproteins (LDL, IDL, VLDL, VHDL, HDL), apolipoproteins (ApoA-1,
ApoA-II, ApoA-IV, ApoC-I, ApoC-II, ApoC-III, ApoD, ApoE), .alpha.-1
Antitrypsin, insulin, proinsullin, follicle stimulating hormone,
calcitonin, oxytocin, vasopressin, leuprolide acetate,
somatostatin, luteinizing hormone, glucagons, clotting factors,
anti-clotting factors, plasminogen activator, human macrophage
inflammatory protein, vascular endothelin growth factor (VEGF),
rheumatoid factors, bone derived neurotrophic factor (BDNF), nerve
growth factor-.beta. (NGF-.beta.), platelet-derived growth factor
(PDGF), fibroblast growth factor (FGF), epidermal growth factor
(EGF), transforming growth factor (TGF-.beta.1, TGF-.beta.2,
TGF-.beta.3, TGF-.beta.4, TGF-.beta.5), erythropoietin,
interleukins (IL-1 to IL-10), bone morphogenic protein (BMP)
parathyroid hormone, DNAse, cationic ferritin, interferon (.alpha.,
.beta., .gamma.) and mixtures thereof.
[0073] In another embodiment of the present invention said protein
is a toxin. In one further embodiment of the instant invention said
toxin is, a botulinum toxin, a diphtheria toxin or a tetanus toxin,
or a mixture of two or more thereof.
[0074] In one embodiment of the present invention the protein in
the said composition is botulinum toxin.
[0075] In one further embodiment of the instant invention said
botulinum toxin is selected from the group consisting of type A, B,
C, C.sub.1, D, E, F and G. In another embodiment of the present
invention said botulinum toxin is type A. In one further embodiment
of the instant invention said protein is the neurotoxic component
of botulinum toxin type A.
[0076] The term "botulinum toxin" as used throughout the present
application, refers to the neurotoxic component devoid of any other
clostridial proteins, but also to the "botulinum toxin complex".
The term "botulinum toxin" is used herein in cases when no
discrimination between the toxin complex and the neurotoxic
component is necessary or desired. "BoNT" or "NT" are commonly used
abbreviations.
[0077] The "neurotoxic component" of the botulinum toxin complex is
initially formed as a single polypeptide chain, having in the case
of serotype A a molecular weight of approximately 150 kDa. In other
serotypes the neurotoxic component has been observed to vary
between about 145 and about 170 kDa, depending on the bacterial
source. In the case of serotype A, for example, proteolytic
processing of the polypeptide results in an activated polypeptide
in the form of a dichain polypeptide consisting of a heavy chain
and a light chain, which are linked by a disulfide bond. In humans,
the heavy chain mediates binding to pre-synaptic cholinergic nerve
terminals and internalization of the toxin into the cell. The term
"neurotoxic component" also includes functional homologs found in
the other serotypes of Clostridium botulinum. In one embodiment of
the present invention, the neurotoxic component is devoid of any
other C. botulinum protein, e.g. also devoid of RNA, which might
potentially be associated with the neurotoxic component. The
neurotoxic component may be the single chain precursor protein of
approximately 150 kDa or the proteolytically processed neurotoxic
component, comprising the light chain (Lc) of approximately 50 kDa
and the heavy chain (Hc) of approximately 100 kDa, which may be
linked by one or more disulfide bonds (for a review see e.g.
Simpson L L, Ann Rev Pharmacol Toxicol. 2004; 44:167-93). In
humans, the heavy chain mediates binding to pre-synaptic
cholinergic nerve terminals and internalization of the toxin into
the cell. The light chain is believed to be responsible for the
toxic effects, acting as zinc-endopeptidase and cleaving specific
proteins responsible for membrane fusion (SNARE complex) (see e.g.
Montecucco C., Shiavo G., Rosetto O: The mechanism of action of
tetanus and botulinum neurotoxins. Arch Toxicol. 1996; 18 (Suppl.):
342-354)).
[0078] The neurotoxic subunit of the botulinum toxin complex is
referred in this document as the "neurotoxic component" or the
"neurotoxic component free of complexing proteins". The production
of the neurotoxic component of botulinum toxin type A and B are
described, for example, in the international patent application WO
00/74703.
[0079] In a further embodiment the botulinum toxin is botulinum
toxin type A. In one embodiment said botulinum toxin is free of any
complexing proteins (neurotoxic component). In one further
embodiment it is the pure neurotoxic component serotype A. In
addition thereto, modified as well as recombinant produced
neurotoxic components of botulinum toxins including the respective
mutations, deletions, etc. are also within the scope of the present
invention. With respect to suitable mutants, reference is made to
WO 2006/027207 A1, WO 2009/015840 A1, WO 2006/114308 A1 and EP
08015287.9 which are fully incorporated by reference herein.
Furthermore, within the present invention, mixtures of various
serotypes (in the form the neurotoxic component or recombinant form
or both forms thereof, e.g. mixtures of botulinum neurotoxins of
types A and B) may be used. The present invention, however, also
refers to toxins, e.g. botulinum toxins, which are chemically
modified, e.g. by pegylation, glycosylation, sulfatation,
phosphorylation or any other modification, in particular of one or
more surface or solvent exposed amino acid(s). Such botulinum
toxins are disclosed in e.g. EP 08015288.7 and the prior art
disclosed therein.
[0080] In accordance with the teaching of the present invention, it
also encompasses that the medicament contains no proteins found in
the botulinum toxin complex other than the neurotoxic
component.
[0081] The botulinum toxin, preferably the neurotoxic component
referred to herein, may be the sole active component or may contain
additional pharmaceutically active components.
[0082] In one embodiment the composition is lyophilized.
[0083] In one embodiment of the instant invention, the liquid
compositions can be filled into lyo-vials and subsequently
lyophilized. Lyophilisation of the samples is conducted by freezing
the samples at temperatures between -35.degree. C. to -65.degree.
C. for a period of from 1 to 10 hours, e.g. 5 to 10 hours. This
step is followed by primary drying at a shelf temperature of
-30.degree. C. to 10.degree. C., e.g. -20.degree. C. to 10.degree.
C. or 5.degree. C. to 10.degree. C. under a pressure of 100 mTorr
to 200 mTorr for a period of 10 hours to 25 hours. Finally, the
samples enter the last step of the lyophilisation process, being
secondary drying, which is conducted at a shelf temperature of
15.degree. C. to 25.degree. C. for 5 hours to 15 hours. Sample
volume in the lyo-vials varies between 0.1 to 5 ml, e.g. 0.2 to 1
ml or 0.4 to 0.6 ml, or 0.5 ml. In one embodiment sample volume is
between 2 ml to 4 ml.
[0084] In one further embodiment of the present invention, the
lyophilisation process can be conducted by freezing the samples at
a shelf temperature of -45.degree. C. for about 2 hours followed by
primary drying at a shelf temperature of -25.degree. C. and 90
mTorr for 12 hours, and secondary drying at a shelf temperature of
25.degree. C. for 12.5 hours.

effects.
[0100] In one aspect the present invention pertains to a kit
comprising one or more containers comprising the
formulation/composition and instructions for use of the
formulation/composition and optionally a pharmaceutically
acceptable sterile solvent.
[0101] The term "solvent" as used herein relates to any liquid
which aids in dissolving or diluting any other substance or
substance mixture or a product. The term "solvent" within the
meaning of the instant invention may encompass also a mixture of

lyophilized.
[0117] Prior to lyophilisation, the protein or peptide is dissolved
in an aqueous solution, which is stabilized by a hydrophilic
polymer, a mixture of polyalcohol and a sugar, a detergent. The
stabilization of the protein in solution means that the protein is
enveloped by a structure composed of hydrophilic polymer, a
detergent and a mixture of polyalcohol and sugar.
[0118] By using a detergent, it is possible to reduce the amount of
hydrophilic polymers. In one embodiment by using Tween 80 the
concentration of PVP was reduced from 150 mg/g to 80 mg/g based on
the total weight of production bulk composition. Due to such an
effect, the industrial production of the composition herein was

[0141] The stability of the formulations were determined by using a
HDA-assay as defined by Goschel et al. ("Botulinum Toxin Therapy:
Neutralizing and Nonneutralizing Antibodies--Therapeutic
Consequences" Experimental Neurology, 1997; 147: 96-102). The start
value was measured after lyophilisation. The mean of all four
experiments is calculated and compared to the data generated by the
reference material. The change of paralysis time over time of
storage indicates the stability of the neurotoxin formulation:
increasing of sample paralysis time compared to original values
indicate a loss of activity of neurotoxin.
[0142] The results are expressed in minutes required to reach half
of the initial muscle concentration force. Shorter time valves
reflect higher amounts of active toxin. The results can be
interpreted as follows: In principle the formulations according to
the present invention are more stable compared to the Comparative
Formulations, wherein one of the constituents required is
missing.
[0143] It becomes apparent from Comparative Formulation 1, in the
absence of sucrose, a formulation with an active toxin may be
prepared, which, however, looses rapidly its activity such that
within 3 months at 40.degree. C. and 75% RH the activity of the
toxin is significantly reduced. Comparative Formulation 2 shows
that in absence of the detergent, the toxin significantly looses
activity already during production, as becomes apparent from the
high starting value of 138 min directly measured after
lyophilization. Comparative Formulation 3 shows that in absence of
the hydrophilic polymer, the toxin significantly looses activity
already during production, as becomes apparent from the high
starting value of 96.
