[0002] Disclosed herein are compositions, formulations, and methods
for treating ocular diseases, inter alia, diabetic macular edema,
age-related macular degeneration (wet form), choroidal
neovascularization, diabetic retinopathy, retinal vein occlusion
(central or branch), ocular trauma, surgery induced edema, surgery
induced neovascularization, cystoid macular edema, ocular ischemia,

BACKGROUND
[0004] The eye comprises several structurally and functionally
distinct vascular beds, which supply ocular components critical to
the maintenance of vision. These include the retinal and choroidal
vasculatures, which supply the inner and outer portions of the
retina, respectively, and the limbal vasculature located at the
periphery of the cornea. Injuries and diseases that impair the
normal structure or function of these vascular beds are among the
leading causes of visual impairment and blindness. For example,
diabetic retinopathy is the most common disease affecting the
retinal vasculature, and is the leading cause of vision loss among
the working age population in the United States. Vascularization of
the cornea secondary to injury or disease is yet another category
of ocular vascular disease that can lead to severe impairment of
vision.

DETAILED DESCRIPTION
[0025] Provided herein are compounds and methods of treating ocular
disorders that are characterized by vascular instability, vascular
leakage, and neovascularization. HPTP-.beta. is a member of the
receptor-like family of the protein tyrosine phosphatases
(PTPases). HPTP-.beta. is a transmembrane protein found primarily
in endothelial cells that displays structural and functional
similarity to cell adhesion molecules (CAMs). HPTP-.beta. is unique
among receptor-like PTPases in that it contains a single catalytic
domain. One of the main functions of HPTP-.beta. is to regulate
Tie-2 negatively.
[0026] Tie-2 is a receptor tyrosine kinase found almost exclusively
in endothelial cells. The principle regulators of Tie-2
phosphorylation are Angiopoietin-1 (Ang-1) and Angiopoietin-2
(Ang-2). Upon Angiopoietin-1 binding to Tie-2, the level of Tie-2
receptor phosphorylation increases. The duration of Tie-2 receptor
phosphorylation is regulated by HPTP-.beta., which cleaves off the
phosphate. Tie-2 receptor phosphorylation helps maintain
endothelial cell proximity; therefore, the duration of Tie-2
receptor phosphorylation is an important determinant of endothelial
cell proximity. For example, when severe inflammation occurs, the
capillary endothelial cells separate, allowing proteins, to enter
the interstitial space. Separation of the capillary endothelial
cells, and subsequent leak of proteins in the interstitial space,
is known as vascular leak and can lead to dangerous hypotension
(low blood pressure), edema, hemoconcentration, and
hypoalbuminemia. Inhibition of HPTP-.beta. leads to increased
levels and Tie-2 receptor phosphorylation, a process that can
maintain or restore capillary endothelial cell proximity.
[0027] The present disclosure relates to compositions and methods
for treating conditions, such as ocular diseases, for example,
those wherein neovasculatization and vascular leakage are present.
These diseases are sometimes characterized as diseases wherein
there is an elevated angiogenic response in the vessels associated
with the eye. The present disclosure provides a Human Protein
Tyrosine Phosphatase-beta (HPTP-.beta.) inhibitor that provides
vascular stabilization.
Human Protein Tyrosine Phosphatase-Beta (HPTP-.beta.)
Inhibitors.
[0028] Compounds disclosed herein can be effective as Tie-2
activators. The compounds can effect that activity, for example, by
binding or inhibiting HPTP-.beta. Such compounds can bind, for
example, by mimicking the binding mechanism of a native substrate,
such as a phosphorylated compound. A compound can be a phosphate
mimetic or bioisostere, for example, a sulfamic acid. The compound
could also be derived from an amino acid building block or comprise
an amino acid backbone for efficiency and economy of synthesis.

4-((S)-2-((S)-2-(Methoxycarbonylamino)-3-phenylpropanamido)-2-(2-ethylthia-
zol-4-yl) ethyl)phenylsulfamic acid [Free Acid Form] (13)
[0356] Preparation of
{1-[2-(S)-(4-(S)-aminophenyl)-1-(2-ethylthiazol-4-yl)ethyl-carbamoyl]-2-p-
henylethyl}-carbamic acid methyl ester (12a): A Parr hydrogenation
vessel is charged with tert-butyl
(S)-1-(S)-2-(4-nitrophenyl)-1-(2-ethylthiazole-4-yl)ethylamino-1-oxo-3-ph-
enylpropan-2-ylcarbamate, 12, (18.05 g, 37.4 mmol, 1.0 eq) and Pd/C
(10% Pd on C, 50% wet, Degussa-type E101 NE/W, 2.68 g, 15 wt %) as
solids. MeOH (270 mL, 15 mL/g) is added to provide a suspension.
The vessel is put on a Parr hydrogenation apparatus. The vessel is
submitted to a fill/vacuum evacuate process with N.sub.2
(3.times.20 psi) to inert, followed by the same procedure with
H.sub.2 (3.times.40 psi). The vessel is filled with H.sub.2 and the
vessel is shaken under 40 psi H.sub.2 for .about.40 hr. The vessel
is evacuated and the atmosphere is purged with N.sub.2 (5.times.20
psi). An aliquot is filtered and analyzed by HPLC to insure
complete conversion. The suspension is filtered through a pad of
celite to remove the catalyst, and the homogeneous yellow filtrate
is concentrated by rotary evaporation to afford 16.06 g (95% yield)
of the desired product as a tan solid, which is used without
further purification.
[0357] Preparation of
4-((S)-2-((S)-2-(methoxycarbonyl)-3-phenylpropanamido)-2-(2-ethylthiazol--
4-yl)ethyl)phenylsulfamic acid (13): A 100 mL RBF is charged with
{1-[2-(S)-(4-(S)-aminophenyl)-1-(2-ethylthiazol-4-yl)ethyl-carbamoyl]-2-p-
henylethyl}-carbamic acid methyl ester, 12a, (10.36 g, 22.9 mmol,
1.0 eq.) prepared in the step described herein above. Acetonitrile
(50 mL, 5 mL/g) is added and the yellow suspension is stirred at
room temperature. A second 3-necked 500 mL RBF is charged with
SO.sub.3. pyr (5.13 g, 32.2 mmol, 1.4 eq.) and acetonitrile (50 mL
5 mL/g) and the white suspension is stirred at room temperature.
Both suspensions are gently heated until the reaction solution
containing
{1-[2-(S)-(4-(S)-aminophenyl)-1-(2-ethylthiazol-4-yl)ethyl-carbamoyl]-2-p-
henylethyl}-carbamic acid methyl ester becomes red-orange in color
(typically for this example about 44.degree. C.). This substrate
containing solution is poured in one portion into the stirring
suspension of SO.sub.3. pyr at 35.degree. C. The resulting opaque
mixture (39.degree. C.) is stirred vigorously while allowed to
slowly cool to room temperature. After stirring for 45 min, the
reaction is determined to be complete by HPLC. H.sub.2O (200 mL, 20
mL/g) is added to the orange suspension to provide a yellow-orange
homogeneous solution having a pH of approximately 2.4. Concentrated
H.sub.3PO.sub.4 is added slowly over 12 minutes to lower the pH to
approximately 1.4. During this pH adjustment, an off-white
precipitate is formed and the solution is stirred at room
temperature for 1 hr. The suspension is filtered and the filter
cake is washed with the filtrate. The filter cake is air-dried on
the filter overnight to afford 10.89 g (89% yield) of the desired
product as a tan solid.

[1-(S)-(Phenylthiazol-2-yl)-2-yl)-2-(4-sulfoaminophenyl)ethyl]-carbamic
acid tert-butyl ester (19)
[0397] Preparation of
[2-(4-nitrophenyl)-1-(S)-(4-phenylthiazol-2-yl)ethyl]-carbamic acid
tert-butyl ester (18): A mixture of
[2-(4-nitrophenyl)-1-(S)-thiocarbamoylethyl]-carbamic acid
tert-butyl ester, 2, (0.343 g, 1.05 mmol), 2-bromoacetophenone
(0.231 g, 1.15 mmol), in CH.sub.3CN (5 mL) is refluxed 1.5 hour.
The solvent is removed under reduced pressure and the residue
re-dissolved in CH.sub.2Cl.sub.2 then pyridine (0.24 mL, 3.0 mmol)
and Boc.sub.2O (0.24 mL, 1.1 mmol) are added. The reaction is
stirred for 2 hours and diethyl ether is added to the solution and
the precipitate which forms is removed by filtration. The organic
layer is dried (Na.sub.2SO.sub.4), filtered, and concentrated to a
residue which is purified over silica to afford 0.176 g (39%) of
the desired product ESI+MS 426 (M+1).
[0398] Preparation of
[1-(S)-(phenylthiazol-2-yl)-2-(4-sulfoaminophenyl)ethyl]-carbamic
acid tert-butyl ester (19):
[2-(4-nitrophenyl)-1-(S)-(4-phenylthiazol-2-yl)ethyl]-carbamic acid
tert-butyl ester, 18, (0.176 g, 0.41 mmol) is dissolved in MeOH (4
mL). A catalytic amount of Pd/C (10% w/w) is added and the mixture
is stirred under a hydrogen atmosphere 12 hours. The reaction
mixture is filtered through a bed of CELITE.TM. and the solvent is
removed under reduced pressure. The crude product is dissolved in
pyridine (12 mL) and treated with SO.sub.3-pyridine (0.195 g, 1.23
mmol). The reaction is stirred at room temperature for 5 minutes
after which a 7% solution of NH.sub.4OH (10 mL) is added. The
mixture is then concentrated and the resulting residue is purified
by reverse phase chromatography to afford 0.080 g of the desired
product as the ammonium salt. .sup.1H NMR (300 MHz, MeOH-d.sub.4)

[0431] Preparation of
N-[1-(4-ethylthiazol-2-yl)-2-(4-nitrophenyl)ethyl]-2-phenyl-acetamide
(20): To a solution of
1-(S)-(4-ethylthiazol-2-yl)-2-(4-nitrophenyl)ethyl amine
hydrobromide, 3, (0.393 g, 1.1 mmol), phenylacetic acid (0.190 g,
1.4 mmol) and 1-hydroxybenzotriazole (HOBt) (0.094 g, 0.70 mmol) in
DMF (10 mL) at 0.degree., is added
1-(3-dimethylaminopropyl)-3-ethylcarbodiimide (EDCI) (0.268 g, 1.4
mmol) followed by triethylamine (0.60 mL, 4.2 mmol). The mixture is
stirred at 0.degree. C. for 30 minutes then at room temperature
overnight. The reaction mixture is diluted with water and extracted
with EtOAc. The combined organic phase is washed with 1 N aqueous
HCl, 5% aqueous NaHCO.sub.3, water and brine, and dried over
Na.sub.2SO.sub.4. The solvent is removed in vacuo to afford 0.260 g
(60% yield) of the desired product which is used without further
purification. ESI+MS 396 (M+1).
[0432] Preparation of
{4-[2-(S)-(4-ethylthiazol-2-yl)-2-(2-phenylacetylamido)ethyl]-phenyl}sulf-
amic acid (21):
N-[1-(4-ethylthiazol-2-yl)-2-(4-nitrophenyl)ethyl]-2-phenyl-acetamide,
20, (0.260 g) is dissolved in MeOH (4 mL). A catalytic amount of
Pd/C (10% w/w) is added and the mixture is stirred under a hydrogen
atmosphere 18 hours. The reaction mixture is filtered through a bed
of CELITE.TM. and the solvent is removed under reduced pressure.
The crude product is dissolved in pyridine (12 mL) and treated with
SO.sub.3-pyridine (0.177 g, 1.23). The reaction is stirred at room
temperature for 5 minutes after which a 7% solution of NH.sub.4OH
(10 mL) is added. The mixture is then concentrated and the
resulting residue is purified by reverse phase chromatography to
afford 0.136 g of the desired product as the ammonium salt. .sup.1H

COMPOSITIONS
[0759] Disclosed are compositions and formulations for
administration to a subject having one or more conditions, for
example, one of the ocular diseases or ocular conditions as
described herein. The compositions can comprise, for example:
[0760] a) a compound herein or a pharmaceutically acceptable salt
thereof; and
[0761] b) a solubilizing system.
[0762] The disclosed compositions can comprise from about 0.1 mg/mL
to about 100 mg/mL of a compound herein.
Solubilizing Systems
[0763] The disclosed solubilizing systems can comprise one or more
pharmaceutically acceptable agents, which alone or in combination
solubilize a compound herein or a pharmaceutically acceptable salt
thereof.
1. Alcohols
[0764] A non-limiting example of a solubilizing agent includes an
organic solvent. Non-limiting examples of organic solvents
includes: alcohols, for example, C.sub.1-C.sub.4 linear alkyl,
C.sub.3-C.sub.4 branched alkyl, for example, ethanol, glycerin,
2-hydroxypropanol, propylene glycol, maltitol, sorbitol, xylitol
and the like; substituted or unsubstituted C.sub.6 or C.sub.10
aryl; substituted or unsubstituted C.sub.7 or C.sub.14
alkylenearyl, for example, benzyl alcohol.
2. Cyclodextrins
[0765] A further non-limiting example of a solubilizing agent
relates to cyclodextrins: .beta.-cyclodextrin, .beta.-cyclodextrin
and .beta.-cyclodextrin and derivatives thereof. Non-limiting
examples of cyclodextrin derivatives includes methyl
.beta.-cyclodextrin, 2-hydroxypropyl-.beta.-cyclodextrin,
sulfobutyl ether-.beta.-cyclodextrin sodium salt, and
2-hydroxypropyl-.beta.-cyclodextrin. A cyclodextrin can possess a
large cyclic structure with a channel passing through the center of
the structure. The interior of the cyclodextrin can be hydrophobic,
and interact favorably with hydrophobic molecules. The exterior of
the cyclodextrin can be highly hydrophilic owing to the several
hydroxyl groups exposed to bulk solvent. Capture of a hydrophobic
molecule, such as a compound disclosed herein, in the channel of
the cyclodextrin can result in formation of a complex stabilized by
non-covalent hydrophobic interactions. The complex can be soluble
in water, and carry the captures hydrophobic molecule into the bulk
solvent.
3. Polyvinylpyrrolidione
[0766] Another non-limiting example of a solubilizing agent are the
polyvinylpyrrolidones (PVP) having the formula:
##STR00324##
wherein the index n is from about 40 to about 200. PVP's can have
an average molecular weight from about 5500 to about 28,000 g/mol.
One non-limiting example is PVP-10, having an average molecular
weight of approximately 10,000 g/mol.
4. Polyakyleneoxides
[0767] A further non-limiting example of solubilizing agents
includes polyalkyleneoxides, and polymers of alcohols or polyols.
Polymers can be mixed, or contain a single monomeric repeat
subunit. For example, polyethylene glycols having an average
molecular weight of from about 200 to about 20,000, for example,
PEG 200, PEG 400, PEG 600, PEG 1000, PEG 1450, PEG 1500, PEG 4000,
PEG 4600, and PEG 8000. In a further embodiment, the compositions
comprise one or more polyethylene glycols chosen from PEG 400, PEG
1000, PEG 1450, PEG 4600 and PEG 8000.
[0768] Other polyalkyleneoxides are polypropylene glycols having
the formula:
HO[CH(CH.sub.3)CH.sub.2O].sub.xH
wherein the index x represents the average number of propyleneoxy
units in the glycol polymer. As in the case of ethylene glycols,
for propylene glycols the index x can be represented by a whole
number or a fraction. For example, a polypropylene glycol having an
average molecular weight of 8,000 g/mole (PEG 8000) can be equally
represented by the formulae:
HO[CH(CH.sub.3)CH.sub.2O].sub.138H or
HO[CH(CH.sub.3)CH.sub.2O].sub.137.6H
or the polypropylene glycol can be represented by the common, short
hand notation: PEG 8000.
[0769] Another example of polypropylene glycols can have an average
molecular weight from about 1200 g/mol to about 20,000 g/mol, i.e.,
a polypropylene glycol having an average molecular weight of about
8,000 g/mol, for example, PEG 8000.
[0770] Another solubilizing agent is Polysorbate 80 (Tween.TM. 80)
which is an oleate ester of sorbitol and its anhydrides
copolymerized with approximately 20 moles of ethylene oxide for
each mole of sorbitol and sorbitol anhydrides. Polysorbate 80 is
made up of sorbitan mono-9-octadecanoate poly(oxy-1,2-ethandiyl)
derivatives.
[0771] Solubilizing agents also include poloxamers having the
formula:
HO(CH.sub.2CH.sub.2).sub.y1(CH.sub.2CH.sub.2CH.sub.2O).sub.y2(CH.sub.2CH-
.sub.2O).sub.y3OH
which are nonionic block copolymers composed of a polypropyleneoxy
unit flanked by two polyethyleneoxy units. The indices y.sup.1,
y.sup.2, and y.sup.3 have values such that the poloxamer has an
average molecular weight of from about 1000 g/mol to about 20,000
g/mol (PLURONICS.TM.). These compound are commonly named with the
word Poloxamer followed by a number to indicate the specific
co-polymer, for example Poloxamer 407 having two PEG blocks of
about 101 units (y.sup.1 and y.sup.3 each equal to 101) and a
polypropylene block of about 56 units and poloxamer 185 [CAS No.
9003-11-6] wherein the indices y.sup.1, y.sup.2, and y.sup.3 have
the average values of 19, 30 and 10 respectively. Various
poloxamers are available under the trade name LUTROL.TM., for
example, LUTROL.TM. F-17. Pluronic F-68 is a commercially available
poloxamer. Other non-limiting examples of suitable poloxamers for
use are those such as poloxamer 188, Pluronic F-68, and the
like.
5. Polyoxyethylene Glycol Alkyl Ethers
[0772] Still further solubilizing agents relate to polyoxyethylene
glycol alkyl ethers having the formula:
RO(CH.sub.2CH.sub.2O).sub.nH
wherein R is a linear or branched alkyl group having from 6 to 20
carbon atoms and n is an integer of about 2 to about 20.
[0773] Examples of these compounds are ethoxylate alcohols such as
the NEODOL.TM. ethoxylated alcohols. NEODOL.TM. 23-1 is a mixture
of R units that are C.sub.12 and C.sub.13 in length with an average
of 1 ethoxy unit. Non-limiting examples of ethoxylated alcohols
include NEODOL.TM. 23-1, NEODOL.TM. 23-2, NEODOL.TM. 23-6.5,
NEODOL.TM. 25-3, NEODOL.TM. 25-5, NEODOL.TM. 25-7, NEODOL.TM. 25-9,
PLURONIC.TM. 12R3, and PLURONIC.TM. 25R2.
6. Polyoxypropylene Glycol Alkyl Ethers
[0774] Yet another example of a solubilizing agent includes
polyoxypropylene glycol alkyl ethers having the formula:
RO(CH.sub.2CH(CH.sub.3)O).sub.nH
wherein R is a linear or branched alkyl group having from 6 to 20
carbon atoms and n is an integer of about 2 to about 20.
[0775] The formulator, however, can use any solubilizing agent or
agents in combination to affect the solubility of a compound
herein.
[0776] One aspect of the disclosure relates to compositions and

Formulation Example 1
[0808] In one non-limiting example, compositions of compounds
herein are prepared as follows. For example, about 100 mg of a
sterile powder of, for example,
4-{(S)-2-[(S)-2-methoxycarbonylamino)-3-phenylpropanamido]-2-[2-(thiophen-
-2-yl)thiazol-4-yl]ethyl}phenylsulfamic acid is diluted in, for
example, about 100 mL water to form a first composition. To the
composition can be added, for example, 250 mg of hydroxypropyl beta
cyclodextrin (HP.beta.CD). Depending upon the formulation, the
administrator of the compound can withdraw a sufficient amount such
that the subject is injected subcutaneously with an amount that
provides from about 5 mg to about 50 mg of the compound. The
formulator, however, can prepare a composition having any
concentration convenient or desirable. Non-limiting examples
according to this embodiment include the following.
TABLE-US-00024 TABLE XXII Compound (mg) HP.beta.CD (mg) Water (mL)

Formulation Example 2
[0809] This formulation example relates to compositions comprising
4-{(S)-2-[(S)-2-(methoxycarbonylamino)-3-phenylpropanamido]-2-[2-(thiophe-
n-2-yl)thiazol-4-yl]ethyl}-phenylsulfamic acid, having the
formula:
##STR00329##
and pharmaceutically acceptable salts thereof.
[0810] Formulation Example 2 comprises: [0811] a)
4-{(S)-2-[(S)-2-methoxycarbonylamino)-3-phenylpropanamido]-2-[2-(thiophen-
-2-yl)thiazol-4-yl]ethyl}phenylsulfamic acid or a pharmaceutically
acceptable salt thereof; [0812] b) a solubilizing system; and
[0813] c) a carrier system.
[0814] The compositions of Formulation Example 2 are formulated to
deliver an amount of
4-{(S)-2-[(S)-2-methoxycarbonylamino)-3-phenylpropanamido]-2-[2-(thiophen-
-2-yl)thiazol-4-yl]ethyl}phenylsulfamic acid in the free acid form.
For example, a composition which comprises 10 mg/mL of
4-{(S)-2-[(S)-2-methoxycarbonylamino)-3-phenylpropanamido]-2-[2-(thiophen-
-2-yl)thiazol-4-yl]ethyl}phenylsulfamic acid can have either 10
mg/mL of the free acid or an amount of a pharmaceutically
acceptable salt in an amount sufficient to deliver 10 mg/mL of the
free acid. As an example, a composition formulated to deliver 10
mg/mL of
4-{(S)-2-[(S)-2-methoxycarbonylamino)-3-phenylpropanamido]-2-[2-(thiophen-
-2-yl)thiazol-4-yl]ethyl}phenyl-sulfamic acid can comprise either
10 mg/mL of
4-{(S)-2-[(S)-2-methoxycarbonylamino)-3-phenylpropanamido]-2-[2-(thiop-
hen-2-yl)thiazol-4-yl]ethyl}phenylsulfamic acid or alternatively
10.4 mg/mL of the sodium salt, (sodium
(4-{(S)-2-[(S)-2-(methoxycarbonylamino)-3-phenyl-propanamido]-2-(2-(thiop-
hen-2-yl)thiazol-4-yl)ethyl}phenyl)sulfamate). Therefore, a
composition which delivers from about 0.1 mg/mL to about 60 mg/mL
of
(4-{(S)-2-[(S)-2-(methoxycarbonylamino)-3-phenylpropanamido]-2-(2-(thioph-
en-2-yl)thiazol-4-yl)ethyl}phenyl)sulfamic acid can comprise an
amount of pharmaceutically acceptable salt thereof to deliver from
about 0.1 mg/mL to about 60 mg/mL of the compound.
[0815] Therefore, when a composition according to Formulation I
comprises an amount of
4-{(S)-2-[(S)-2-methoxycarbonylamino)-3-phenylpropanamido]-2-[2-(thiophen-
-2-yl)thiazol-4-yl]ethyl}phenylsulfamic acid per mL, it is
understood that this amount is the amount of free acid that is
delivered and if a salt form of the compound is used in the
composition, the amount of the salt form can therefore reflect the
difference in molecular weight between the free acid and the salt
form. The following example demonstrates this equivalency.
[0816] A composition delivering 10 mg/mL of
4-{(S)-2-[(S)-2-methoxycarbonylamino)-3-phenylpropanamido]-2-[2-(thiophen-
-2-yl)thiazol-4-yl]ethyl}phenylsulfamic acid, comprises: [0817] a)
10 mg/mL of
4-{(S)-2-[(S)-2-(methoxycarbonylamino)-3-phenylpropanamido]-2-[2-
-(thiophen-2-yl)thiazol-4-yl]ethyl}phenylsulfamic acid; or about
10.4 mg/mL of sodium
(4-{(S)-2-[(S)-2-(methoxycarbonylamino)-3-phenyl-propanamido]-2-(2-(thiop-
hen-2-yl)thiazol-4-yl)ethyl}phenyl)sulfamate; or about 10.3 mg/mL
of ammonium
(4-{(S)-2-[(S)-2-(methoxycarbonylamino)-3-phenylpropanamido]-2-(-
2-(thiophen-2-yl)thiazol-4-yl)ethyl}phenyl)sulfamate, and the like;
[0818] b) an amount of a solubilizing system; and [0819] c) a
carrier system.
[0820] The disclosed compositions according to Formulation Example
2 according to Formulation Example 2 comprise from about 0.1 mg/mL
to about 60 mg/mL of
4-{(S)-2-[(S)-2-methoxycarbonylamino)-3-phenylpropanamido]-2-[2-(thiophen-
-2-yl)thiazol-4-yl]ethyl}phenylsulfamic acid or a pharmaceutically
acceptable salt thereof.
[0821] In one aspect the disclosed compositions according to
Formulation Example 2 comprise from about 0.5 mg/mL to about 60
mg/mL of a compound herein or a pharmaceutically acceptable salt
thereof. In one embodiment, the composition comprises from about 5
mg/mL to about 40 mg/mL of a compound herein or a pharmaceutically
acceptable salt thereof. In another embodiment, the composition
comprises from about 10 mg/mL to about 40 mg/mL of a compound
herein or a pharmaceutically acceptable salt thereof. In a further
embodiment, the composition comprises from about 10 mg/mL to about
30 mg/mL of a compound herein or a pharmaceutically acceptable salt
thereof. In a still further embodiment, the composition comprises
from about 0.5 mg/mL to about 20 mg/mL of a compound herein or a
pharmaceutically acceptable salt thereof. In a further embodiment
the composition comprises from about 1 mg/mL to about 20 mg/mL
weight by volume of a compound herein or a pharmaceutically

comprises from about 15 mg/mL to about 30 mg/mL weight by volume of
a compound herein or a pharmaceutically acceptable salt thereof. In
another embodiment, the composition comprises from about 10 mg/mL
to about 50 mg/mL weight by volume of a compound herein or a
pharmaceutically acceptable salt thereof.

[0826] The disclosed solubilizing systems comprise
2-hydroxypropyl-beta-cyclodextrin (HP.beta.-CD).
2-Hydroxypropyl-.beta.-cyclodextrin [CAS No. 128446-35-5] is
commercially available as Cavitron.TM..
2-Hydroxypropyl-.beta.-cyclodextrin, also described herein as
hydroxypropyl-.beta.-cyclodextrin,
2-hydroxypropyl-beta-cyclodextrin, hydroxypropyl-beta-cyclodextrin
or HP.beta.CD, can be represented by either of the following
formulae:
##STR00330##
[0827] The average molecular weight of HP.beta.CD as provided under
the name Cavitron.TM., is approximately 1396 Da wherein the average
degree of substitution is from about 0.5 to about 1.3 units of
2-hydroxypropyl per ring glucose unit. For calculation purposes it
is convenient for the formulator to use 1400 Da as the molecular
weight of HP.beta.CD.
[0828] For example, a composition according to Formulation Example
2 comprising from about 0.1 mg/mL to about 60 mg/mL of the compound
or a pharmaceutically acceptable salt thereof can comprise from
about 0.25 mg/mL to about 500 mg/mL of HP.beta.CD. Stated another
way, a composition comprising about 10 mg/mL of a disclosed
composition can comprise from 40 mg/mL (1:4) to about 80 mg/mL
(1:8) of HP.beta.CD. The formulator can adjust the ratios of
compound to HP.beta.CD based upon composition parameters, for
example, choice and amount of a tonicity agent, pH, and the
like.
[0829] The following are non-limiting examples of ratios of
compound or a pharmaceutically acceptable salt and HP.beta.CD: 1:4,

[0830] As such, the compositions can comprise an amount of
HP.beta.CD suitable for achieving the desired properties of the
composition, i.e., concentration of a compound, such as
4-{(S)-2-[(S)-2-methoxy-carbonylamino)-3-phenylpropanamido]-2-[2-(thiophe-
n-2-yl)thiazol-4-yl]ethyl}phenylsulfamic acid, the desired
viscosity, and the desired osmolarity. The amount of HP.beta.CD can
vary depending upon the amount of the compound that the formulator
desires to deliver in a single dose.
Carrier System
[0831] The disclosed compositions according to Formulation Example
2 comprise from about 1.35% to about 90% weight by volume of a

according to Formulation Example 2. The tonicity agent can comprise
from about 0.5% to about 5% weight by volume of the final
composition. In non-limiting examples, when preparing the final
composition, the tonicity agent may be combined with
4-{(S)-2-[(S)-2-methoxycarbonylamino)-3-phenylpropanamido]-2-[2-(thiophen-
-2-yl)thiazol-4-yl]ethyl}phenylsulfamic acid before mixing with the
carrier system. Alternately, when reconstituting the final

mg of
4-{(S)-2-[(S)-2-methoxy-carbonylamino)-3-phenylpropanamido]-2-[2-(thiophe-
n-2-yl)thiazol-4-yl]ethyl}phenyl-sulfamic acid), etc.
Dry Compositions
[0968] The disclosed compositions according to Formulation Example
2 can be re-constituted from a dry or solid composition. As such
the dry or solid compositions comprise: [0969] a)
4-{(S)-2-[(S)-2-methoxy-carbonylamino)-3-phenylpropanamido]-2-[2-(thiophe-
n-2-yl)thiazol-4-yl]ethyl}phenyl-sulfamic acid or a
pharmaceutically acceptable salt thereof; and [0970] b)
HP.beta.CD.
[0971] The dry compositions are prepared such that upon
re-constitution with a carrier system described herein, the
resulting aqueous composition delivers from about 0.5 mg/mL to
about 60 mg/mL of the
4-{(S)-2-[(S)-2-methoxycarbonylamino)-3-phenylpropanamido]-2-[2-(thiophen-
-2-yl)thiazol-4-yl]ethyl}phenylsulfamic acid or a pharmaceutically
acceptable salt thereof.
[0972] As in the aqueous compositions described herein, the ratio
of the
4-{(S)-2-[(S)-2-methoxycarbonylamino)-3-phenylpropanamido]-2-[2-(thiophen-
-2-yl)thiazol-4-yl]ethyl}phenylsulfamic acid to HP.beta.CD is from
about 1:4 to about 1:8. The amount of dry material in a container
that can be reconstituted can vary depending upon the number of
doses of dry material desired. For example, a single 15 mg/mL dose
of the compound can be sealed or otherwise placed in a container
that has an exact volume such that when the composition is
re-constituted, an amount of composition that is reconstituted has
15 mg/mL of a compound.
[0973] In another embodiment, the dry compositions comprise: [0974]
a)
4-{(S)-2-[(S)-2-methoxy-carbonylamino)-3-phenylpropanamido]-2-[2-(thiophe-
n-2-yl)thiazol-4-yl]ethyl}phenyl-sulfamic acid or a
pharmaceutically acceptable salt thereof; [0975] b) HP.beta.CD; and
[0976] c) a tonicity agent; wherein the ratio of
4-{(S)-2-[(S)-2-(methoxycarbonylamino)-3-phenylpropanamido]-2-[2-(thiophe-
n-2-yl)thiazol-4-yl]ethyl}phenylsulfamic acid to HP.beta.CD is from
about 1:4 to about 1:8 and the tonicity agent is present in an
amount such that the re-constituted formula comprises from about
0.5% to about 5% weight to volume of the tonicity agent.
[0977] The use of further solubilizing agents was examined. In a
first test of further solubilizing agents, polyvinylpyrrolidone
(PVP) having the formula:
##STR00331##
wherein the index n is from about 40 to about 200 was tested. PVP's
have an average molecular weight from about 5500 to about 28,000
g/mol. One non limiting example is PVP-10 having an average
molecular weight of approximately 10,000 g/mol available from
Sigma-Aldrich.
[0978] The follow experiments were undertaken to determine the
suitability of formulating a composition comprising PVP and
HP.beta.CD as a solubilizing system for sodium
4-{(S)-2-[(S)-2-(methoxycarbonylamino)-3-phenylpropanamido]-2-[2-(thiophe-
n-2-yl)thiazol-4-yl]ethyl}phenylsulfamate. The following is a
non-limiting example.
Example 29
[0979] To a 25 mL volumetric flask containing 20 mL of distilled
water is charged hydroxylpropyl-.beta.-cyclodextrin (2.5 g) and
polyvinylpyrrolidone, PVP-10, (0.125 g) and the solution stirred at
room temperature for 0.5 hours. Additional water was added to bring
the final volume to 25 mL. The following compositions were prepared
according to this procedure.

solutions 1, 2 and 3 and stirred for 6 hours at room temperature to
provide a nominal concentration of 52 mg/mL. Similarly, the
compound (1500 mg) was added to solutions 4 5, and 6 and stirred
for 6 hours at room temperature to provide a nominal concentration
of 60 mg/mL. Table XXV lists the solution obtained herein

Summary of Results
[0981] All compositions comprising polyvinylpyrrolidones were hazy
upon 2 hours of standing or yielded a suspension. Experiments 10,
11 and 12 yielded a gel upon standing. Compositions formulated in
the manner of Example 30 having only a PVP (no HP.beta.CD) formed a
hazy initial solution that setup as a gel and remained such upon
standing for 3 days.
[0982] In one aspect of the disclosed compositions according to
Formulation Example 2, the compositions do not comprise
poylvinylpyrrolidone or a derivative thereof. Compositions which
gel upon standing cannot be injected parentally, e.g.,
subcutaneously and, therefore, are incompatible with the disclosed
compositions according to Formulation Example 2. This is because
the temperature during shipment and storage of the compositions
result in physical properties, i.e., formation of a gel that cannot
be administered by the artisan.
[0983] In a further aspect of the disclosed compositions according
to Formulation Example 26, the compositions do not comprise
poylvinylpyrrolidone or a derivative thereof in combination with
2-hydroxypropyl-.beta.-cyclodextrin.
[0984] The follow experiments were undertaken to determine the
suitability of formulating a composition comprising a quaternary
ammonium salt, PVP and HP.beta.CD as a solubilizing system for
sodium
4-{(S)-2-[(S)-2-methoxycarbonylamino)-3-phenylpropanamido]-2-[2-(thiophen-
-2-yl)thiazol-4-yl]ethyl}phenylsulfamate. The following is a
non-limiting example.
Preparation of Stock Solution
[0985] Benzalkonium chloride (BAC; alkylbenzyldimethylammonium
chloride, alkyl: C.sub.8-C.sub.18 available from Sigma-Aldrich)

ophen-2-yl)thiazol-4-yl)ethyl}phenyl)-sulfamate (1.14 g). The
volume was made up to 25 mL with the addition of more stock
solution. The resulting suspension was stirred for 1 hour at
20.degree. C. The solution was filtered through 0.65 micron then
0.45 micron filter paper and 5 mL of the filtrate was transferred
to 3 separate vials. One vial was held at each of the following
temperatures 4.degree. C., 20.degree. C. and 40.degree. C.
Example 31

(4-{(S)-2-[(S)-2-(methoxycarbonylamino)-3-phenylpropanamido]-2-(2-(2-(thi-
ophen-2-yl)thiazol-4-yl)ethyl}phenyl)-sulfamate (1.14 g). The
volume was made up to 25 mL with the addition of more stock
solution. The resulting suspension was stirred for 1 hour at
20.degree. C. The solution was filtered through 0.65 micron then
0.45 micron filter paper, however, the flow rate was extremely
slow. 5 mL of the filtrate was transferred to 3 separate vials. One
vial was held at each of the following temperatures 4.degree. C.,
20.degree. C. and 40.degree. C.
Example 32
[0988] To a 25 mL volumetric flask is added the stock solution
(22.8 mL followed by polyvinylpyrrolidone (Povidone 437190.TM. ex
Sigma-Aldrich) (0.5 g) and sodium
(4-{(S)-2-[(S)-2-(methoxycarbonylamino)-3-phenylpropanamido]-2-(2-(2-(thi-
ophen-2-yl)thiazol-4-yl)ethyl}phenyl)-sulfamate (1.43 g). The
volume was made up to 25 mL with the addition of more stock
solution. The resulting suspension was stirred for 1 hour at
20.degree. C. Attempt to filter solution through 0.65 micron then
0.45 micron filter paper and 5 mL of the filtrate was unsuccessful.

Excipients.
[1009] A pharmaceutical composition of the invention can be a
combination of any pharmaceutical compounds described herein with
other chemical components, such as carriers, stabilizers, diluents,
dispersing agents, suspending agents, thickening agents, and/or
excipients. The pharmaceutical composition facilitates
administration of the compound to an organism. Pharmaceutical
compositions can be administered in therapeutically-effective
amounts as pharmaceutical compositions by various forms and routes
including, for example, intravenous, subcutaneous, intramuscular,
oral, rectal, aerosol, parenteral, ophthalmic, pulmonary,
transdermal, vaginal, otic, nasal, and topical administration.
[1010] A pharmaceutical composition can be administered in a local
or systemic manner, for example, via injection of the compound
directly into an organ, optionally in a depot or sustained release
formulation. Pharmaceutical compositions can be provided in the
form of a rapid release formulation, in the form of an extended
release formulation, or in the form of an intermediate release
formulation. A rapid release form can provide an immediate release.
An extended release formulation can provide a controlled release or
a sustained delayed release.
[1011] For oral administration, pharmaceutical compositions can be
formulated readily by combining the active compounds with
pharmaceutically-acceptable carriers or excipients. Such carriers
can be used to formulate tablets, powders, pills, dragees,
capsules, liquids, gels, syrups, elixirs, slurries, suspensions and
the like, for oral ingestion by a subject.
[1012] Pharmaceutical preparations for oral use can be obtained by
mixing one or more solid excipient with one or more of the
compounds described herein, optionally grinding the resulting
mixture, and processing the mixture of granules, after adding
suitable auxiliaries, if desired, to obtain tablets or dragee
cores. Cores can be provided with suitable coatings. For this
purpose, concentrated sugar solutions can be used, which can
contain an excipient such as gum arabic, talc,
polyvinylpyrrolidone, carbopol gel, polyethylene glycol, and/or
titanium dioxide, lacquer solutions, and suitable organic solvents
or solvent mixtures. Dyestuffs or pigments can be added to the
tablets or dragee coatings, for example, for identification or to
characterize different combinations of active compound doses.
[1013] Pharmaceutical preparations which can be used orally include
push-fit capsules made of gelatin, as well as soft, sealed capsules
made of gelatin and a plasticizer, such as glycerol or sorbitol. In
some embodiments, the capsule comprises a hard gelatin capsule
comprising one or more of pharmaceutical, bovine, and plant
gelatins. A gelatin can be alkaline-processed. The push-fit
capsules can contain the active ingredients in admixture with
filler such as lactose, binders such as starches, and/or lubricants
such as talc or magnesium stearate and, stabilizers. In soft
capsules, the active compounds can be dissolved or suspended in
suitable liquids, such as fatty oils, liquid paraffin, or liquid
polyethylene glycols. Stabilizers can be added. All formulations
for oral administration are provided in dosages suitable for such
administration.
[1014] For buccal or sublingual administration, the compositions
can be tablets, lozenges, or gels.
[1015] Parental injections can be formulated for bolus injection or
continuous infusion. The pharmaceutical compositions can be in a
form suitable for parenteral injection as a sterile suspension,
solution or emulsion in oily or aqueous vehicles, and can contain
formulatory agents such as suspending, stabilizing and/or
dispersing agents. Pharmaceutical formulations for parenteral
administration include aqueous solutions of the active compounds in
water-soluble form. Suspensions of the active compounds can be
prepared as oily injection suspensions. Suitable lipophilic
solvents or vehicles include fatty oils such as sesame oil, or
synthetic fatty acid esters, such as ethyl oleate or triglycerides,
or liposomes. Aqueous injection suspensions can contain substances
which increase the viscosity of the suspension, such as sodium
carboxymethyl cellulose, sorbitol, or dextran. The suspension can
also contain suitable stabilizers or agents which increase the
solubility of the compounds to allow for the preparation of highly
concentrated solutions. Alternatively, the active ingredient can be
in powder form for constitution with a suitable vehicle, e.g.,
sterile pyrogen-free water, before use.
[1016] The active compounds can be administered topically and can
be formulated into a variety of topically administrable
compositions, such as solutions, suspensions, lotions, gels,
pastes, medicated sticks, balms, creams, and ointments. Such
pharmaceutical compositions can contain solubilizers, stabilizers,
tonicity enhancing agents, buffers and preservatives.
[1017] Formulations suitable for transdermal administration of the
active compounds can employ transdermal delivery devices and
transdermal delivery patches, and can be lipophilic emulsions or
buffered aqueous solutions, dissolved and/or dispersed in a polymer
or an adhesive. Such patches can be constructed for continuous,
pulsatile, or on demand delivery of pharmaceutical compounds.
Transdermal delivery can be accomplished by means of iontophoretic
patches. Additionally, transdermal patches can provide controlled
delivery. The rate of absorption can be slowed by using
rate-controlling membranes or by trapping the compound within a
polymer matrix or gel. Conversely, absorption enhancers can be used
to increase absorption. An absorption enhancer or carrier can
include absorbable pharmaceutically acceptable solvents to assist
passage through the skin. For example, transdermal devices can be
in the form of a bandage comprising a backing member, a reservoir
containing compounds and carriers, a rate controlling barrier to
deliver the compounds to the skin of the subject at a controlled
and predetermined rate over a prolonged period of time, and
adhesives to secure the device to the skin or the eye.
[1018] For administration by inhalation, the active compounds can
be in a form as an aerosol, a mist, or a powder. Pharmaceutical
compositions are conveniently delivered in the form of an aerosol
spray presentation from pressurized packs or a nebuliser, with the
use of a suitable propellant, for example, dichlorodifluoromethane,
trichlorofluoromethane, dichlorotetrafluoroethane, carbon dioxide
or other suitable gas. In the case of a pressurized aerosol, the
dosage unit can be determined by providing a valve to deliver a
metered amount. Capsules and cartridges of, for example, gelatin
for use in an inhaler or insufflator can be formulated containing a
powder mix of the compounds and a suitable powder base such as
lactose or starch.
[1019] The compounds can also be formulated in rectal compositions
such as enemas, rectal gels, rectal foams, rectal aerosols,
suppositories, jelly suppositories, or retention enemas, containing
conventional suppository bases such as cocoa butter or other
glycerides, as well as synthetic polymers such as
polyvinylpyrrolidone and PEG. In suppository forms of the
compositions, a low-melting wax such as a mixture of fatty acid
glycerides or cocoa butter can be used.
[1020] In practicing the methods of treatment or use provided
herein, therapeutically-effective amounts of the compounds
described herein are administered in pharmaceutical compositions to
a subject having a disease or condition to be treated. In some
embodiments, the subject is a mammal such as a human. A
therapeutically-effective amount can vary widely depending on the
severity of the disease, the age and relative health of the
subject, the potency of the compounds used, and other factors. The
compounds can be used singly or in combination with one or more
therapeutic agents as components of mixtures.
[1021] Pharmaceutical compositions can be formulated using one or
more physiologically-acceptable carriers comprising excipients and
auxiliaries, which facilitate processing of the active compounds
into preparations that can be used pharmaceutically. Formulation
can be modified depending upon the route of administration chosen.
Pharmaceutical compositions comprising a compounds described herein
can be manufactured, for example, by mixing, dissolving,
granulating, dragee-making, levigating, emulsifying, encapsulating,
entrapping, or compression processes.
[1022] The pharmaceutical compositions can include at least one
pharmaceutically acceptable carrier, diluent, or excipient and
compounds described herein as free-base or
pharmaceutically-acceptable salt form. The methods and
pharmaceutical compositions described herein include the use
crystalline forms (also known as polymorphs), and active
metabolites of these compounds having the same type of
activity.
[1023] Methods for the preparation of compositions comprising the
compounds described herein include formulating the compounds with
one or more inert, pharmaceutically-acceptable excipients or
carriers to form a solid, semi-solid, or liquid composition. Solid
compositions include, for example, powders, tablets, dispersible
granules, capsules, cachets, and suppositories. Liquid compositions
include, for example, solutions in which a compound is dissolved,
emulsions comprising a compound, or a solution containing
liposomes, micelles, or nanoparticles comprising a compound as
disclosed herein. Semi-solid compositions include, for example,
gels, suspensions and creams. The compositions can be in liquid
solutions or suspensions, solid forms suitable for solution or
suspension in a liquid prior to use, or as emulsions. These
compositions can also contain minor amounts of nontoxic, auxiliary
substances, such as wetting or emulsifying agents, pH buffering
agents, and other pharmaceutically-acceptable additives.
[1024] Non-limiting examples of dosage forms suitable for use in
the invention include feed, food, pellet, lozenge, liquid, elixir,
aerosol, inhalant, spray, powder, tablet, pill, capsule, gel,
geltab, nanosuspension, nanoparticle, microgel, suppository
troches, aqueous or oily suspensions, ointment, patch, lotion,
dentifrice, emulsion, creams, drops, dispersible powders or
granules, emulsion in hard or soft gel capsules, syrups,
phytoceuticals, nutraceuticals, and any combination thereof.
[1025] Non-limiting examples of pharmaceutically-acceptable
excipients suitable for use in the invention include granulating
agents, binding agents, lubricating agents, disintegrating agents,
sweetening agents, glidants, anti-adherents, anti-static agents,
surfactants, anti-oxidants, gums, coating agents, coloring agents,
flavouring agents, coating agents, plasticizers, preservatives,
suspending agents, emulsifying agents, anti-microbial agents, plant
cellulosic material and spheronization agents, and any combination
thereof.
[1026] A composition of the invention can be, for example, an
immediate release form or a controlled release formulation. An
immediate release formulation can be formulated to allow the
compounds to act rapidly. Non-limiting examples of immediate
release formulations include readily dissolvable formulations. A
controlled release formulation can be a pharmaceutical formulation
that has been adapted such that drug release rates and drug release
profiles can be matched to physiological and chronotherapeutic
requirements or, alternatively, has been formulated to effect
release of a drug at a programmed rate. Non-limiting examples of
controlled release formulations include granules, delayed release
granules, hydrogels (e.g., of synthetic or natural origin), other
gelling agents (e.g., gel-forming dietary fibers), matrix-based
formulations (e.g., formulations comprising a polymeric material
having at least one active ingredient dispersed through), granules
within a matrix, polymeric mixtures, and granular masses.
[1027] The disclosed compositions can optionally comprise from
about 0.001% to about 0.005% weight by volume pharmaceutically
acceptable preservatives. One non-limiting example of a suitable
preservative is benzyl alcohol.
[1028] In some, a controlled release formulation is a delayed
release form. A delayed release form can be formulated to delay a
compound's action for an extended period of time. A delayed release
form can be formulated to delay the release of an effective dose of
one or more compounds, for example, for about 4, about 8, about 12,
about 16, or about 24 hours.
[1029] A controlled release formulation can be a sustained release
form. A sustained release form can be formulated to sustain, for
example, the compound's action over an extended period of time. A
sustained release form can be formulated to provide an effective
dose of any compound described herein (e.g., provide a
physiologically-effective blood profile) over about 4, about 8,
about 12, about 16 or about 24 hours.
[1030] Non-limiting examples of pharmaceutically-acceptable
excipients can be found, for example, in Remington: The Science and
Practice of Pharmacy, Nineteenth Ed (Easton, Pa.: Mack Publishing
Company, 1995); Hoover, John E., Remington's Pharmaceutical
Sciences, Mack Publishing Co., Easton, Pa. 1975; Liberman, H. A.
and Lachman, L., Eds., Pharmaceutical Dosage Forms, Marcel Decker,
New York, N.Y., 1980; and Pharmaceutical Dosage Forms and Drug
Delivery Systems, Seventh Ed. (Lippincott Williams & Wilkins
1999), each of which is incorporated by reference in its
entirety.
[1031] The disclosed methods include administration of a
HPTP-.beta. inhibitor or a pharmaceutically acceptable salt thereof
in combination with a pharmaceutically acceptable carrier. The
carrier can be selected to minimize any degradation of the active
ingredient and to minimize any adverse side effects in the
subject.
[1032] In another aspect, the 4 HPTP-.beta. inhibitor or a
pharmaceutically acceptable salt thereof can be used
prophylactically, i.e., as a preventative agent after treatment
with an anti-VEGF agent has stopped. The HPTP-.beta. inhibitor or a
pharmaceutically acceptable salt thereof herein can be conveniently
formulated into pharmaceutical compositions composed of one or more
pharmaceutically acceptable carriers. See e.g., Remington's
Pharmaceutical Sciences, latest edition, by E.W. Martin Mack Pub.
Co., Easton, Pa., which discloses typical carriers and conventional
methods of preparing pharmaceutical compositions that can be used
in conjunction with the preparation of formulations of the compound
described herein and which is incorporated by reference herein.
Such pharmaceutical can be standard carriers for administration of
compositions to humans and non-humans, including solutions such as
sterile water, saline, and buffered solutions at physiological pH.
Other compositions can be administered according to standard
procedures used by those skilled in the art. For example,
pharmaceutical compositions can also include one or more additional
active ingredients such as antimicrobial agents, anti-inflammatory
agents, anesthetics, and the like.
[1033] Non-limiting examples of pharmaceutically-acceptable
carriers include, but are not limited to, saline, Ringer's solution
and dextrose solution. The pH of the solution can be from about 5
to about 8, and can be from about 7 to about 7.5. Further carriers
include sustained release preparations such as semipermeable
matrices of solid hydrophobic polymers containing the HPTP-.beta.
inhibitor or a pharmaceutically-acceptable salt thereof, which
matrices are in the form of shaped articles, e.g., films,
liposomes, microparticles, or microcapsules.
[1034] The disclosed methods relate to administering the
HPTP-.beta. inhibitor or a pharmaceutically acceptable salt thereof
as part of a pharmaceutical composition. Compositions suitable for
topical administration can be used (see, for example, US Patent
Application 2005/0059639 included herein by reference in its
entirety). In various embodiments, compositions of the invention
can comprise a liquid comprising an active agent in solution, in
suspension, or both. Liquid compositions can include gels. In one
embodiment, the liquid composition is aqueous. Alternatively, the
composition can take form of an ointment. In another embodiment,
the composition is an in situ gellable aqueous composition. In
iteration, the composition is an in situ gellable aqueous solution.
Such a composition can comprise a gelling agent in a concentration
effective to promote gelling upon contact with the eye or lacrimal
fluid in the exterior of the eye. Aqueous compositions of the
invention have ophthalmically compatible pH and osmolality. The
composition can comprise an ophthalmic depot formulation comprising
an active agent for subconjunctival administration. The
microparticles comprising active agent can be embedded in a
biocompatible pharmaceutically acceptable polymer or a lipid
encapsulating agent. The depot formulations may be adapted to
release all or substantially all the active material over an
extended period of time. The polymer or lipid matrix, if present,
may be adapted to degrade sufficiently to be transported from the
site of administration after release of all or substantially all
the active agent. The depot formulation can be a liquid
formulation, comprising a pharmaceutical acceptable polymer and a
dissolved or dispersed active agent. Upon injection, the polymer
forms a depot at the injections site, e.g. by gelifying or
precipitating. The composition can comprise a solid article that
can be inserted in a suitable location in the eye, such as between
the eye and eyelid or in the conjunctival sac, where the article
releases the active agent. Solid articles suitable for implantation
in the eye in such fashion generally comprise polymers and can be
bioerodible or non-bioerodible.
[1035] Pharmaceutical formulations can include additional carriers,
as well as thickeners, diluents, buffers, preservatives, surface
active agents and the like in addition to the compounds disclosed
herein. Pharmaceutical formulations can also include one or more
additional active ingredients such as antimicrobial agents,
anti-inflammatory agents, anesthetics, and the like.
[1036] An excipient can fill a role as simple and direct as being
an inert filler, or an excipient as used herein may be part of a pH
stabilizing system or coating to insure delivery of the ingredients
safely to the stomach. The formulator can also take advantage of
the fact the compounds of the present disclosure have improved
cellular potency, pharmacokinetic properties, as well as improved
oral bioavailability.
[1037] The HPTP-.beta. inhibitor or a pharmaceutically acceptable
salt thereof can also be present in liquids, emulsions, or
suspensions for delivery of active therapeutic agents in aerosol
form to cavities of the body such as the nose, throat, or bronchial
passages. The ratio of HPTP-.beta. inhibitor or a pharmaceutically
acceptable salt thereof to the other compounding agents in these
preparations can vary as the dosage form requires.
[1038] Depending on the intended mode of administration, the
pharmaceutical compositions administered as part of the disclosed
methods can be in the form of solid, semi-solid or liquid dosage
forms, such as, for example, tablets, suppositories, pills,
capsules, powders, liquids, suspensions, lotions, creams, gels, or
the like, for example, in unit dosage form suitable for single
administration of a precise dosage. The compositions can, as noted
above, an effective amount of the HPTP-.beta. inhibitor or a
pharmaceutically acceptable salt thereof in combination with a
pharmaceutically acceptable carrier and, in addition, can include
other medicinal agents, pharmaceutical agents, carriers, adjuvants,
diluents, etc.
[1039] For solid compositions, conventional nontoxic solid carriers
include, for example, pharmaceutical grades of mannitol, lactose,
starch, magnesium stearate, sodium saccharin, talc, cellulose,
glucose, sucrose, magnesium carbonate, and the like. In one
embodiment, a composition comprising the HPTP-.beta. inhibitor or a
pharmaceutically acceptable salt thereof in an amount of
approximately 5 mg per 0.1 mL liquid is prepared. The liquid phase
comprises sterile water and an appropriate amount of a saccharide
or polysaccharide.

Formulation Example 3
[1144] This formulation example relates to compositions comprising
4-{(S)-2-[(S)-2-(methoxycarbonylamino)-3-phenylpropanamido]-2-(2-ethylthi-
azol-4-yl)ethyl}phenyl-sulfamic acid having the formula:
##STR00334##
and pharmaceutically acceptable salts thereof.
[1145] Formulation Example 3 comprises: [1146] a)
4-{(S)-2-[(S)-2-(methoxycarbonylamino)-3-phenylpropanamido]-2-(2-ethylthi-
azol-4-yl)ethyl}phenylsulfamic acid or a pharmaceutically
acceptable salt thereof; [1147] b) a solubilizing system; and
[1148] c) a carrier system.
[1149] The compositions of Formulation Example 3 are formulated to
deliver an amount of
4-{(S)-2-[(S)-2-(methoxycarbonylamino)-3-phenylpropanamido]-2-(2-ethylthi-
azol-4-yl)ethyl}phenylsulfamic acid in the free acid form. For
example, a composition which comprises 10 mg/mL of
4-{(S)-2-[(S)-2-(methoxycarbonylamino)-3-phenylpropanamido]-2-(2-ethylthi-
azol-4-yl)ethyl}phenylsulfamic acid can have either 10 mg/mL of the
free acid or an amount of a pharmaceutically acceptable salt in an
amount sufficient to deliver 10 mg/mL of the free acid. As an
example, a composition formulated to deliver 10 mg/mL of
4-{(S)-2-[(S)-2-(methoxycarbonylamino)-3-phenylpropanamido]-2-(2-ethylthi-
azol-4-yl)ethyl}phenylsulfamic acid can comprise either 10 mg/mL of
4-{(S)-2-[(S)-2-(methoxycarbonylamino)-3-phenylpropanamido]-2-(2-ethylthi-
azol-4-yl)ethyl}phenylsulfamic acid or alternatively 10.4 mg/mL of
the sodium salt, (sodium
4-{(S)-2-[(S)-2-(methoxycarbonylamino)-3-phenylpropanamido]-2-(2-ethylthi-
azol-4-yl)ethyl}phenylsulfamate). Therefore, a composition which
delivers from about 10 mg/mL to about 100 mg/mL of
4-{(S)-2-[(S)-2-(methoxycarbonylamino)-3-phenylpropanamido]-2-(2-ethylthi-
azol-4-yl)ethyl}phenylsulfamic acid can comprise an amount of
pharmaceutically acceptable salt thereof to deliver from about 10
mg/mL to about 100 mg/mL of the compound
[1150] Therefore, when a composition according to Formulation
Example 3 comprises an amount of
4-{(S)-2-[(S)-2-(methoxycarbonylamino)-3-phenylpropanamido]-2-(2-ethylthi-
azol-4-yl)ethyl}phenylsulfamic acid per mL, it is understood that
this amount is the amount of free acid that is delivered and if a
salt form of the compound is used in the composition, the amount of
the salt form can therefore reflect the difference in molecular
weight between the free acid and the salt form. The following
example demonstrates this equivalency.
[1151] A composition delivering 10 mg/mL of
4-{(S)-2-[(S)-2-(methoxycarbonylamino)-3-phenylpropanamido]-2-(2-ethythia-

4-{(S)-2-[(S)-2-(methoxycarbonylamino)-3-phenylpropanamido]-2-(2-ethythia-
zol-4-yl)ethyl}phenylsulfamate; or about 10.3 mg/mL, of ammonium
4-{(S)-2-[(S)-2-(methoxycarbonylamino)-3-phenylpropanamido]-2-(2-ethythia-

[1161] As such, the compositions can comprise an amount of
HP.beta.CD suitable for achieving the desired properties of the
composition, i.e., concentration of
4-{(S)-2-[(S)-2-(methoxycarbonyl-amino)-3-phenylpropanamido]-2-(2-ethylth-
iazol-4-yl)ethyl}phenylsulfamic acid, the desired viscosity, the
desired osmolarity and the like. The amount of HP.beta.CD can vary
depending upon the amount of
4-{(S)-2-[(S)-2-(methoxycarbonylamino)-3-phenylpropanamido]-2-(2-ethylthi-
azol-4-yl)ethyl}phenylsulfamic acid the formulator desires to
deliver in a single dose.
Carrier System
[1162] The disclosed compositions according to Formulation Example
3 comprise from about 1.5% to about 90% weight by volume of a
carrier system. The amount of carrier system present is based upon
several different factors or choices made by the formulator, for
example, the final concentration of the compound and the amount of
solubilizing agent.
[1163] The following is a non-limiting example of a composition
comprising 60 mg/mL of
4-{(S)-2-[(S)-2-(methoxycarbonylamino)-3-phenylpropanamido]-2-(2-ethylthi-
azol-4-yl)ethyl}-phenylsulfamic acid: [1164] a) 60 mg of the
4-{(S)-2-[(S)-2-(methoxycarbonylamino)-3-phenylpropanamido]-2-(2-ethythia-
zol-4-yl)ethyl}phenylsulfamic acid; [1165] b) 5 mg of
2-hydroxypropyl-beta-cyclodextrin; and [1166] c) the balance a
carrier system to a volume of 1 mL.
[1167] In one aspect, the carrier system comprises:
[1168] i) one or more tonicity agents; and
[1169] ii) water.
[1170] Non-limiting examples of tonicity agents include dextrose,
mannitol and glycerin. The formulator can utilize more than one
tonicity agent when formulating the disclosed compositions
according to Formulation Example 3. The tonicity agent can comprise
from about 0.5% to about 5% weight by volume of the final
composition. In non-limiting examples, when preparing the final
composition, the tonicity agent may be combined with
4-{(S)-2-[(S)-2-(methoxycarbonyl-amino)-3-phenylpropanamido]-2-(2-ethylth-
iazol-4-yl)ethyl}phenylsulfamic acid before mixing with the carrier
system. Alternately, when reconstituting the final composition the
formulator can use commercially available solutions containing a
tonicity agent, for example, 5% Dextrose Injection, USP.
[1171] The osmolarity of the disclosed compositions according to
Formulation Example 3 can be within any range chosen by the
formulator. In one aspect the osmolarity is from about 250 to about
350 mOsm/L. In one embodiment of this aspect of the disclosed
osmolarity is from about 270 to about 310 mOsm/L.
[1172] The pH of the disclosed compositions according to
Formulation Example 3 can be from about 6 to about 8. If the pH is
outside the range desired by the formulator, the pH can be adjusted
by using sufficient pharmaceutically acceptable acids and
bases.
[1173] One aspect of the disclosed compositions according to
Formulation Example 3 relates to compositions comprising

Formulation Example 4
[1216] This formulation example relates to compositions comprising
4-{(S)-2-[(S)-2-(methoxycarbonylamino)-3-phenylpropanamido]-2-(4-ethylthi-
azol-2-yl)ethyl}phenylsulfamic acid having the formula:
##STR00335##
and pharmaceutically acceptable salts thereof.
[1217] Formulation Example 4 comprises: [1218] a)
4-{(S)-2-[(S)-2-(methoxycarbonylamino)-3-phenylpropanamido]-2-(4-ethylthi-
azol-2-yl)ethyl}phenylsulfamic acid or a pharmaceutically
acceptable salt thereof; [1219] b) a solubilizing system; and
[1220] c) a carrier system.
[1221] The compositions of Formulation Example 4 are formulated to
deliver an amount of
4-{(S)-2-[(S)-2-(methoxycarbonylamino)-3-phenylpropanamido]-2-(4-ethylthi-
azol-2-yl)ethyl}-phenylsulfamic acid in the free acid form. For
example, a composition which comprises 10 mg/mL of
4-{(S)-2-[(S)-2-(methoxycarbonylamino)-3-phenylpropanamido]-2-(4-ethylthi-
azol-2-yl)ethyl}phenylsulfamic acid can have either 10 mg/mL of the
free acid or an amount of a pharmaceutically acceptable salt in an
amount sufficient to deliver 10 mg/mL of the free acid. As an
example, a composition formulated to deliver 10 mg/mL of
4-{(S)-2-[(S)-2-(methoxy-carbonylamino)-3-phenylpropanamido]-2-(4-ethylth-
iazol-2-yl)ethyl}phenylsulfamic acid can comprise either 10 mg/mL
of
4-{(S)-2-[(S)-2-(methoxycarbonylamino)-3-phenylpropanamido]-2-(4-ethylthi-
azol-2-yl)ethyl}phenylsulfamic acid or alternatively 10.4 mg/mL of
the sodium salt, (sodium
4-{(S)-2-[(S)-2-(methoxycarbonylamino)-3-phenylpropanamido]-2-(4-ethylthi-
azol-2-yl)ethyl}phenylsulfamate). Therefore, a composition which
delivers from about 0.1 mg/mL to about 90 mg/mL of
4-{(S)-2-[(S)-2-(methoxycarbonylamino)-3-phenylpropanamido]-2-(4-ethylthi-
azol-2-yl)ethyl}phenylsulfamic acid can comprise an amount of
pharmaceutically acceptable salt thereof to deliver from about 0.1
mg/mL to about 90 mg/mL of the compound
[1222] Therefore, when a composition according to Formulation
Example 4 comprises an amount of
4-{(S)-2-[(S)-2-(methoxycarbonylamino)-3-phenylpropanamido]-2-(4-ethylthi-
azol-2-yl)ethyl}phenylsulfamic acid per mL, it is understood that
this amount is the amount of free acid that is delivered and if a
salt form of the compound is used in the composition, the amount of
the salt form can therefore reflect the difference in molecular
weight between the free acid and the salt form. The following
example demonstrates this equivalency.
[1223] A composition delivering 10 mg/mL of
4-{(S)-2-[(S)-2-(methoxycarbonylamino)-3-phenylpropanamido]-2-(4-ethythia-
zol-2-yl)ethyl}phenylsulfamic acid, comprises: [1224] a) 10 mg/mL
of
4-{(S)-2-[(S)-2-(methoxycarbonylamino)-3-phenylpropanamido]-2-(4-ethythia-
zol-2-yl)ethyl}phenylsulfamic acid; or about 10.4 mg/mL of sodium
4-{(S)-2-[(S)-2-(methoxycarbonylamino)-3-phenylpropanamido]-2-(4-ethythia-
zol-2-yl)ethyl}phenylsulfamate; or about 10.3 mg/mL, of ammonium
4-{(S)-2-[(S)-2-(methoxycarbonylamino)-3-phenylpropanamido]-2-(4-ethythia-
zol-2-yl)ethyl}phenylsulfamate, and the like; [1225] b) an amount
of 2-hydroxypropyl-.beta.-cyclodextrin as defined herein; and
[1226] c) a carrier system.
[1227] The disclosed compositions according to Formulation Example
4 according to Formulation Example 4 comprise from about 10 mg/mL
to about 90 mg/mL of the
4-{(S)-2-[(S)-2-(methoxycarbonylamino)-3-phenylpropanamido]-2-[4-ethylthi-
azol-2-yl]ethyl}phenyl-sulfamic acid or a pharmaceutically
acceptable salt thereof.
[1228] In one aspect the disclosed compositions according to
Formulation Example 4 comprise from about 20 mg/mL to about 100
mg/mL of
4-{(S)-2-[(S)-2-(methoxycarbonylamino)-3-phenylpropanamido]-2-[4-ethylthi-
azol-2-yl]ethyl}phenylsulfamic acid or a pharmaceutically
acceptable salt thereof. In one embodiment, the composition
comprises from about 15 mg/mL to about 60 mg/mL of
4-{(S)-2-[(S)-2-(methoxycarbonylamino)-3-phenylpropanamido]-2-[4-ethylthi-
azol-2-yl]ethyl}phenylsulfamic acid or a pharmaceutically
acceptable salt thereof. In another embodiment, the composition
comprises from about 40 mg/mL to about 90 mg/mL of
4-{(S)-2-[(S)-2-(methoxycarbonylamino)-3-phenylpropanamido]-2-(4-ethylthi-
azol-2-yl)ethyl}-phenylsulfamic acid or a pharmaceutically
acceptable salt thereof. In a further embodiment, the composition
comprises from about 10 mg/mL to about 30 mg/mL of

iazol-2-yl)ethyl}phenylsulfamic acid or a pharmaceutically
acceptable salt thereof. In a still further embodiment, the
composition comprises from about 40 mg/mL to about 80 mg/mL of
4-{(S)-2-[(S)-2-(methoxycarbonyl-lamino)-3-phenylpropanamido]-2-(4-ethylt-
hiazol-2-yl)ethyl}phenylsulfamic acid or a pharmaceutically
acceptable salt thereof. In a yet further embodiment the
composition comprises from about 10 mg/mL to about 20 mg/mL weight
by volume of
4-{(S)-2-[(S)-2-(methoxycarbonylamino)-3-phenylpropanamido]-2-[4-ethylthi-
azol-2-yl]ethyl}phenylsulfamic acid or a pharmaceutically
acceptable salt thereof. In a still yet further embodiment, the
composition comprises from about 60 mg/mL to about 90 mg/mL weight
by volume of

[1230] In one embodiment, the disclosed compositions according to
Formulation Example 4 can comprise from a ratio of about 20 parts
of the compound herein or a pharmaceutically acceptable salt
thereof to about 1 part solubilizing system (about 20:about 1) to

[1231] The formulator can adjust the ratios of the compound to
HP.beta.CD based upon composition parameters, for example, choice
and amount of a tonicity agent and pH. Suitable ratios are
described above. As such, the compositions can comprise an amount
of solubilizing system suitable for achieving the desired
properties of the composition, i.e., concentration of compound, the
desired viscosity, and the desired osmolarity. The amount of
HP.beta.CD can vary depending upon the amount of compound that the
formulator desires to deliver in a single dose.
Carrier System
[1232] The disclosed compositions according to Formulation Example
4 can comprise from about 1.5% to about 90% weight by volume of a

Methods
[1291] Disclosed are methods for the treatment of diseases or
conditions of the eye, especially diabetic macular edema,
age-related macular degeneration (wet form), choroidal
neovascularization, diabetic retinopathy, ocular ischemia, uveitis,
retinal vein occlusion (central or branch), ocular trauma, surgery
induced edema, surgery induced neovascularization, cystoid macular
edema, ocular ischemia, uveitis, and the like. These diseases or
conditions are characterized by changes in the ocular vasculature
whether progressive or non-progressive, whether a result of an
acute disease or condition, or a chronic disease or condition.
These diseases can be characterized by an increased level of plasma
Vascular Endothelial Growth Factor.
[1292] In some embodiments, the disclosed methods relate to the
administration of the HPTP-.beta. inhibitor or a pharmaceutically
acceptable salt thereof, as well as compositions comprising the
HPTP-.beta. inhibitor or a pharmaceutically acceptable salt
thereof.
[1293] In some embodiments, the methods of the disclosure are drawn
towards co-administration of a HPTP-.beta. inhibitor or a
pharmaceutically acceptable salt thereof which stabilizes the
vasculature against leakage and one or more anti-VEGF agents.
[1294] In some embodiments, the methods of the disclosure are drawn
towards co-administration of a HPTP-.beta. inhibitor or a
pharmaceutically acceptable salt thereof which stabilizes the
vasculature against neovascularization and one or more anti-VEGF
agents.
[1295] In some embodiments, the inhibitor stabilizes the
vasculature against leakage and neovascularization.
[1296] In one embodiment of the disclosed methods, a human subject
with at least one visually impaired eye is treated with from about
0.1 mg to about 100 mg of the HPTP-3 inhibitor or a
pharmaceutically acceptable salt thereof via subcutaneous or
intravitreal injection. Improvement of clinical symptoms can be
monitored by one or more methods known to the art, for example,
indirect ophthalmoscopy, fundus photography, fluorescein
angiopathy, electroretinography, external eye examination, slit
lamp biomicroscopy, applanation tonometry, pachymetry, optical
coherence tomography and autorefaction. As described herein, the
dosing can occur at any frequency determined by the administrator.
After cessation of the anti-VEGF agent treatment, subsequent doses
can be administered weekly or monthly, e.g., with a frequency of
2-8 weeks or 1-12 months apart depending upon the response.
[1297] One aspect of the disclosed methods relates to diseases that
are a direct or indirect result of diabetes, inter alia, diabetic
macular edema and diabetic retinopathy. The ocular vasculature of
the diabetic becomes unstable over time leading to conditions such
as non-proliferative retinopathy, macular edema, and proliferative
retinopathy. As fluid leaks into the center of the macula, the part
of the eye where sharp, straight-ahead vision occurs, the buildup
of fluid and the associated protein begin to deposit on or under
the macula. This results in swelling that causes the subject's
central vision to gradually become distorted. This condition is
referred to as "macular edema." Another condition that may occur is
non-proliferative retinopathy in which vascular changes, such as
microaneurysms, outside the macular region of the eye may be
observed.
[1298] These conditions may or may not progress to diabetic
proliferative retinopathy which is characterized by increased
neovascularization. These new blood vessels are fragile and are
susceptible to bleeding. The result is scaring of the retina, as
well as occlusion or total blockage of the light pathway through
the eye due to the over formation of new blood vessels. Typically
subjects having diabetic macular edema are suffering from the
non-proliferative stage of diabetic retinopathy; however, it is not
uncommon for subjects to only begin manifesting macular edema at
the onset of the proliferative stage.
[1299] Diabetic retinopathy is the most common cause of vision loss
in working-aged Americans (Klein R et al., "The Wisconsin
Epidemiologic Study of Diabetic Retinopathy. II. Prevalence and
risk of diabetic retinopathy when age at diagnosis is less than 30
years," Arch. Ophthalmol. 1984, 102:520-526). Severe vision loss
occurs due to tractional retinal detachments that complicate
retinal neovascularization (NV), but the most common cause of
moderate vision loss is diabetic macular edema (DME). The
pathogenesis of diabetic macular edema is not completely
understood, but hypoxia is a contributing factor (Nguyen Q D et
al., "Supplemental inspired oxygen improves diabetic macular edema;
a pilot study," Invest. Ophthalmol. Vis. Sci. 2003, 45:617-624).
Vascular endothelial growth factor (Vegf) is a hypoxia-regulated
gene and VEGF levels are increased in hypoxic or ischemic retina.
Injection of VEGF into mouse eyes causes breakdown of the inner
blood-retinal barrier (See, Derevjanik N L et al. Quantitative
assessment of the integrity of the blood-retinal barrier in mice,
Invest. Ophthalmol. Vis. Sci. 2002, 43:2462-2467) and sustained
release of VEGF in the eyes of monkeys causes macular edema (Ozaki
H et al., "Intravitreal sustained release of VEGF causes retinal
neovascularization in rabbits and breakdown of the blood-retinal
barrier in rabbits and primates," Exp Eye Res 1997, 64:505-517).
This combination of observations in patients and animal models led
to the hypothesis that VEGF plays an important role in the
pathogenesis of diabetic macular edema. This hypothesis has been
confirmed by several clinical trials that have shown that VEGF
antagonists reduce foveal thickening and improve vision in patients
with diabetic macular edema (Nguyen Q D et al., "Vascular
endothelial growth factor is a critical stimulus for diabetic
macular edema," Am. J. Ophthalmol. 2006, 142:961-969; and Nguyen Q
D et al. "Primary End Point (Six Months) Results of the Ranibizumab
for Edema of the mAcula in Diabetes (READ-2) Study," Ophthalmology
2009, 116:2175-2181).
[1300] The effects of VEGF on vascular endothelial cells are
modulated by Tie2 receptors, which are selectively expressed on
vascular endothelial cells and are required for embryonic vascular
development (Dumont D J et al., "Dominant-negative and targeted
null mutations in the endothelial receptor tyrosine kinase, tek,
reveal a critical role in vasculogenesis of the embryo," Genes Dev.
1994, 8:1897-1909). Angiopoietin 1 (Ang1) binds Tie2 with high
affinity and initiates phosphorylation and downstream signaling
(Davis S et al., "Isolation of angiopoietin-1, a ligand for the
TIE2 receptor, by secretion-trap expression cloning," Cell 1996,
87:1161-1169). Mice deficient in Ang1 die around E12.5 with
vascular defects similar to, but less severe than those seen in
Tie2-deficient mice. Angiopoietin 2 (Ang2) binds Tie2 with high
affinity, but does not stimulate phosphorylation in cultured
endothelial cells. It acts as a competitive inhibitor of Ang1 and
transgenic mice overexpressing Ang2 have a phenotype similar to
Ang1-deficient mice. Several lines of evidence indicate that Ang2
is a developmentally- and hypoxia-regulated permissive factor for
VEGF-induced neovascularization in the retina (Hackett S F et al.,
"Angiopoietin 2 expression in the retina: upregulation during
physiologic and pathologic neovascularization," J. Cell. Physiol.
2000, 184:275-284). Double transgenic Tet/opsin/ang2 and
Tet/opsin/ang1 mice with inducible expression of Ang2 or Ang1,
respectively, have also helped to elucidate the role of Tie2 in the
retina (Nambu H et al., "Angiopoietin 1 inhibits ocular
neovascularization and breakdown of the blood-retinal barrier,"
Gene Ther. 2004, 11:865-873). In mice with ischemic retinopathy,
increased expression of Ang2 when VEGF is high (P12-17) increases
retinal neovascularization, but increased expression at P20 when
VEGF levels have come down, hastens regression of retinal
neovascularization and findings were similar in other models of
ocular neovascularization. In contrast, increased expression of
Ang1 suppressed neovascularization and reduced vascular leakage in
several models. Therefore, Ang2 reduces stabilizing signals from
the matrix making endothelial cells dependent upon VEGF and other
soluble stimulators; when VEGF is high, neovascularization is
stimulated and when VEGF is low, neovascularization regresses. In
contrast, Ang1 increases stabilizing signals from the matrix and
makes the vasculature unresponsive to soluble stimulators like
VEGF.
[1301] Angiopoietin 2 binds Tie2, but does not stimulate
phosphorylation and therefore acts as an antagonist under most
circumstances. In the eye, angiopoietin 2 is upregulated at sites
of neovascularization and acts as a permissive factor for VEGF.
Increased expression of VEGF in the retina does not stimulate
sprouting of neovascularization from the superficial or
intermediate capillary beds of the retina or the choriocapillaris,
but does stimulate sprouting from the deep capillary bed where
there is constitutive expression of angiopoietin 2 (Hackett S F et
al., "Angiopoietin-2 plays an important role in retinal
angiogenesis," J. Cell. Physiol. 2002, 192:182-187). Co-expression
of VEGF and angiopoietin 2 at the surface of the retina causes
sprouting of neovascularization from the superficial retinal
capillaries (Oshima Y et al., "Angiopoietin-2 enhances retinal
vessel sensitivity to vascular endothelial growth factor," J. Cell.
Physiol. 2004, 199:412-417). In double transgenic mice with
inducible expression of angiopoietin 2 in the retina, expression of
angiopoietin 2 when VEGF levels were high markedly enhanced
neovascularization and expression of angiopoietin 2 when VEGF
levels were low caused regression of neovascularization. In double
transgenic mice with inducible expression of angiopoietin 1, the
induced expression of angiopoietin 1 in the retina strongly
suppressed VEGF-induced vascular leakage or neovascularization
(Nambu H et al., "Angiopoietin 1 inhibits ocular neovascularization
and breakdown of the blood-retinal barrier," Gene Ther. 2004,
11:865-873). In fact, in mice with high expression of VEGF in the
retina which develop severe NV and retinal detachment, angiopoietin
1 is able to prevent the VEGF-induced detachments.
[1302] Regulation of Tie2 also occurs through an
endothelial-specific phosphatase, vascular endothelial protein
tyrosine phophatase (VE-PTP) in mice (Fachinger G et al.,
"Functional interaction of vascular endothelial-protein-tyrosine
phosphatase with the angiopoietin receptor Tie-2," Oncogene 1999,
18:5948-5943) and its human orthologue human protein tyrosine
phosphatase-.beta. (HPTP-.beta.) (Krueger N X et al., "Structural
diversity and evolution of human receptor-like protein tyrosine
phosphatases," EMBO J. 1990, 9:3241-3252). Mice deficient in VE-PTP
die at E10 with severe defects in vascular remodeling and
maturation of developing vasculature. Silencing of HPTP-.beta. in
cultured human endothelial cells, enhances Ang1-induced
phosphorylation of Tie2 and survival-promoting activity while
hypoxia increases expression of HPTP-.beta. and reduces
Ang1-induced phosphorylation of Tie2 (Yacyshyn O K et al.,
"Thyrosine phosphatase beta regulates angiopoietin-Tie2 signaling
in human endothelial cells," Angiogenesis 2009, 12:25-33).
[1303] Macular degeneration is a condition characterized by a
gradual loss or impairment of eyesight due to cell and tissue
degeneration of the yellow macular region in the center of the
retina. Macular degeneration is often characterized as one of two
types, non-exudative (dry form) or exudative (wet form). Although
both types are bilateral and progressive, each type may reflect
different pathological processes. The wet form of age-related
macular degeneration (AMD) is the most common form of choroidal
neovascularization and a leading cause of blindness in the elderly.
AMD affects millions of Americans over the age of 60, and is the
leading cause of new blindness among the elderly.
[1304] Choroidal neovascular membrane (CNVM) is a problem that is
related to a wide variety of retinal diseases, but is most commonly
linked to age-related macular degeneration. With CNVM, abnormal
blood vessels stemming from the choroid (the blood vessel-rich
tissue layer just beneath the retina) grow up through the retinal
layers. These new vessels are very fragile and break easily,
causing blood and fluid to pool within the layers of the
retina.
[1305] Diabetes (diabetes mellitus) is a metabolic disease caused
by the inability of the pancreas to produce insulin or to use the
insulin that is produced. The most common types of diabetes are
type 1 diabetes (often referred to as Juvenile Onset Diabetes
Mellitus) and type 2 diabetes (often referred to as Adult Onset
Diabetes Mellitus). Type 1 diabetes results from the body's failure
to produce insulin due to loss of insulin producing cells, and
presently requires the person to inject insulin. Type 2 diabetes
generally results from insulin resistance, a condition in which
cells fail to use insulin properly.
[1306] Diabetes can be correlated to a large number of other
conditions, including conditions or diseases of the eye including
diabetic retinopathy (DR) and diabetic macular edema (DME) which
are leading causes of vision loss and blindness in most developed
countries. The increasing number of individuals with diabetes
worldwide suggests that DR and DME continues to be major
contributors to vision loss and associated functional impairment
for years to come.
[1307] Diabetic retinopathy is a complication of diabetes that
results from damage to the blood vessels of the light-sensitive
tissue at the back of the eye (retina). At first, diabetic
retinopathy may cause no symptoms or only mild vision problems.
Eventually, however, diabetic retinopathy can result in blindness.
Diabetic retinopathy can develop in anyone who has type 1 diabetes
or type 2 diabetes.
[1308] At its earliest stage, non-proliferative retinopathy,
microaneurysms occur in the retina's tiny blood vessels. As the
disease progresses, more of these blood vessels become damaged or
blocked and these areas of the retina send signals into the
regional tissue to grow new blood vessels for nourishment. This
stage is called proliferative retinopathy. The new blood vessels
grow along the retina and along the surface of the clear, vitreous
gel that fills the inside of the eye. By themselves, these blood
vessels do not cause symptoms or vision loss. However, they have
thin, fragile walls and without timely treatment, these new blood
vessels can leak blood (whole blood or some constituents thereof)
which can result in severe vision loss and even blindness. Also,
fluid can leak into the center of the macula, the part of the eye
where sharp, straight-ahead vision occurs. The fluid and the
associated protein begin to deposit on or under the macula swell
the patient's central vision becomes distorted. This condition is
called macular edema. It can occur at any stage of diabetic
retinopathy, although it is more likely to occur as the disease
progresses. About half of the people with proliferative retinopathy
also have macular edema.
[1309] Uveitis is a condition in which the uvea becomes inflamed.
The eye is shaped much like a tennis ball, hollow on the inside
with three different layers of tissue surrounding a central cavity.
The outermost is the sclera (white coat of the eye) and the
innermost is the retina. The middle layer between the sclera and
the retina is called the uvea. The uvea contains many of the blood
vessels that nourish the eye. Complications of uveitis include
glaucoma, cataracts or new blood vessel formation
(neovascularization).
[1310] Ocular trauma is any sort of physical or chemical injury to
the eye. Ocular trauma can affect anyone and major symptoms include
redness or pain in the affected eye. Neither symptom may occur if
tiny projectiles are the cause of the trauma.
[1311] Surgery-induced edema is the development of swelling in the
eye tissues following surgery on the retina or other part of the
eye. Cystoid macular edema (CME) is an example of this phenomenon.
CME can occur not only in people who have had cataract surgery, but
also those with diabetes, retinitis pigmentosa, AMD, or conditions
that cause chronic inflammation in the eye. The major symptoms of
CME are blurred or decreased central vision.
[1312] Ocular ischemic syndrome (OIS) encompasses the signs and
symptoms that result from chronic vascular insufficiency. It is
caused by ocular hypoperfusion due to occlusion or stenosis of the
common or internal carotid arteries. OIS generally affects those
between the ages of 50-80 and they may also have systemic diseases
such as hypertension or diabetes. The major symptoms of OIS are
orbital pain, vision loss, changes of the visual field, asymmetric
cataract, and sluggish reaction to light, among a variety of other
symptoms.
[1313] Retinal vein occlusion (RVO) is the most common retinal
vascular disease after diabetic retinopathy. Depending on the area
of retinal venous drainage effectively occluded, it is broadly
classified as either central retinal vein occlusion (CRVO),
hemispheric retinal vein occlusion (HRVO), or branch retinal vein
occlusion (BRVO). It has been observed that each of these has two
subtypes. Presentation of RVO in general is with variable painless
visual loss with any combination of fundal findings consisting of
retinal vascular tortuosity, retinal hemorrhages (blot and flame
shaped), cotton wool spots, optic disc swelling and macular edema.
In a CRVO, retinal hemorrhages can be found in all four quadrants
of the fundus, whilst these are restricted to either the superior
or inferior fundal hemisphere in a HRVO. In a BRVO, hemorrhages are
largely localized to the area drained by the occluded branch
retinal vein. Vision loss occurs secondary to macular edema or
ischemia.
[1314] Angiogenesis, the process of creating new blood vessels from
pre-existing vessels, is essential to a wide range of physiological
and pathological events including embryological development,
menstruation, wound healing, and tumor growth. Most, if not all,
tumors require angiogenesis to grow and proliferate. VEGF has been
shown to a major factor in angiogenesis where it can increase
vessel permeability and capillary number. Due to the essential
function of angiogenesis in tumor development, much effort has been
put forth to develop therapies that target regulators of
angiogenesis, including VEGF.
[1315] Vascular endothelial growth factor (VEGF) is a protein that
is primarily found in endothelial cells and has functions in
vasculogenesis, angiogenesis, and permeabilization of blood
vessels. The expression of VEGF is induced by hypoxia, activated
oncogenes, and cytokines. It has been found that VEGF activation
not only leads to angiogenesis in normal human cells and tissues,
but also angiogenesis in tumors, allowing for tumor progression and
growth. Inhibition of VEGF inhibits tumor growth leading to tumor
regression. A variety of retinopathies are associated with
increased levels of VEGF; ischemia in the eye leads to an induction
of VEGF production due to lack of oxygen. This increase in VEGF can
cause hyperproliferation of blood vessels in the retina, eventually
leading to blindness. The disclosed HPTP-.beta. inhibitors act to
stabilize ocular vasculature and, in some embodiments, a compound
of the invention serves to counter act the stimulation caused by
VEGF and other inflammatory agents that can be present in the
diseased retina. In some embodiments, administration of HPTP-.beta.
inhibitors to a subject can be used to maintain the level of
disease reversal after administration of anti-VEGF drugs to the
subject have been withdrawn.
[1316] Diabetic retinopathy, if left untreated, can lead ultimately
to blindness. Indeed, diabetic retinopathy is the leading cause of
blindness in working-age populations.
[1317] Therefore, the disclosed methods relate to preventing,
treating, controlling, abating, and/or otherwise minimizing ocular
neovascularization in a subject having diabetes or a subject
diagnosed with diabetes. In addition, subjects having or subjects
diagnosed with diabetes can be alerted to or can be made aware of
the risks of developing diabetes-related blindness, therefore the
present methods can be used to prevent or delay the onset of
non-proliferative retinopathy in subjects known to be at risk.
Likewise, the present methods can be used for treating subjects
having or being diagnosed with non-proliferative diabetic
retinopathy to prevent progression of the condition.
[1318] The disclosed methods relate to preventing or controlling
ocular neovascularization or treating a disease or condition that
is related to the onset of ocular neovascularization by
administering to a subject the
4-{(S)-2-[(S)-2-methoxycarbonylamino)-3-phenylpropanamido]-2-[2-(thiophen-
-2-yl)thiazol-4-yl]ethyl}phenylsulfamic acid s and one or more
anti-VEGF agents as disclosed herein.
[1319] Unlike previous ocular treatments which comprise
administration of an anti-VEGF agent, inter alia, ranibizumab
(Lucentis.TM.), bevacizumab (Avastin.TM.) and aflibercept
(Eylea.TM.), wherein these vascular leak inhibitors are injected
directly into the eye itself, the HPTP-.beta. inhibitor or a
pharmaceutically acceptable salt thereof can be administered
systemically or into the eye. The HPTP-.beta. inhibitor or a
pharmaceutically acceptable salt thereof can be used to increase or
enhance the effect of anti-VEGF agents, thereby improving the rate
and magnitude of the response and reducing the number of
treatments.
[1320] In one aspect, the HPTP-.beta. inhibitor or a
pharmaceutically acceptable salt thereof are administered in
combination with one or more pharmaceutical compounds or
compositions useful for treating ocular diseases. In one

decrease in Central Foveal Thickness is from about 250 .mu.m to
about 650 .mu.m. In a yet still further embodiment, the decrease in
Central Foveal Thickness is from about 200 .mu.m to about 500
.mu.m. In another still further embodiment, the decrease in Central
Foveal Thickness is from about 400 .mu.m to about 700 .mu.m.
[1452] Further disclosed herein are methods for increasing the
visual acuity of a subject having a disease or condition as
disclosed herein.
Visual Acuity
[1453] Visual acuity (VA) is acuteness or clearness of vision,
which is dependent on the sharpness of the retinal focus within the
eye and the sensitivity of the interpretative faculty of the brain.
Visual acuity is a measure of the spatial resolution of the visual
processing system. VA is tested by requiring the person whose
vision is being tested to identify characters typically numbers or
letters on a chart from a set distance. Chart characters are
represented as black symbols against a white background. The
distance between the person's eyes and the testing chart is set at
a sufficient distance to approximate infinity in the way the lens
attempts to focus. Twenty feet, or six meters, is essentially
infinity from an optical perspective. In the present disclosure, an
improvement in visual acuity was assessed by an increase in the
number of letters read from the chart.
[1454] Visual Acuity Testing.
[1455] One non-limiting test for measuring Visual Acuity is the use
of the ESV-3000 ETDRS testing device (see, U.S. Pat. No. 5,078,486)
self-calibrated test lighting. The ESV-3000 device incorporates
highly advanced LED light source technology. The auto-calibration
circuitry constantly monitors the LED light source and calibrates
the test luminance to 85 cd/m2 or 3 cd/m2.
[1456] Although designed for clinical trials where large-format
ETDRS testing (up to 20/200) is performed at 4 meters, the device
can be used in a non-research setting, i.e., hospital or clinic
where ocular disease monitoring is conducted. To properly evaluate
ETDRS, the test should be conducted under standardized lighting
conditions, for, example, photopic test level of 85 cd/m2. This
light level has been recommended by the National Academy of
Sciences and by the American National Standards Institute for ETDRS
and contrast sensitivity vision testing. Scoring of visual acuity
can be accomplished in any manner chosen by the monitor. After
providing a baseline evaluation, the increase or decrease in the
number of letters that can be identified by the test subject
provides a measure of sight increase or decrease during
treatment.
[1457] In one aspect, disclosed herein is a method for increasing
visual acuity in a subject having a disease or condition of the eye
as disclosed herein. This method comprises administering to a
patient having a disease or condition of the eye:
[1458] a) a HPTP-.beta. inhibitor or a pharmaceutically acceptable
salt thereof; and
[1459] b) one or more anti-VEGF agents;
[1460] A further embodiment of this aspect relates to a method for
increasing visual acuity in a subject, comprising administering to
a patient having a disease or condition of the eye: [1461] a) a
disclosed HPTP-.beta. inhibitor or a pharmaceutically acceptable
salt thereof; and [1462] b) one or more anti-VEGF agents; wherein
the administration of the HPTP-.beta. inhibitor or a
pharmaceutically acceptable salt thereof and the anti-VEGF agent
can be conducted in any manner desired by the administrator, for
example, as further described herein.
[1463] In some embodiments, the disclosure provides a method for
increasing visual acuity, the method comprising administering to a
subject in need thereof a compound disclosed herein.
[1464] In one embodiment, the method provides a method for
increasing the number of letters recognizable by a treated eye form
about 1 to about 30 letters. In another embodiment, the number of
letters recognizable is increased from about 5 to about 25 letters.
In a further embodiment, the number of letters recognizable is
increased from about 5 to about 20 letters. In another further
embodiment, the number of letters recognizable is increased from
about 5 to about 15 letters. In a still further embodiment, the
number of letters recognizable is increased from about 5 to about
10 letters. In a yet another embodiment, the number of letters
recognizable is increased from about 10 to about 25 letters. In a
yet still further embodiment, the number of letters recognizable is
increased from about 15 to about 25 letters. In yet still another
embodiment, the number of letters recognizable is increased from
about 20 to about 25 letters. The increase in visual acuity can be

Baseline Study for Determining the Effectiveness of the Disclosed
Methods for Treating Ocular Diseases.
[1465] Described herein below is a study of four human subjects
with visual acuity loss due to diabetic macular edema (central
retinal thickness [CRT] of more than 325 microns and best corrected
visual acuity less than 70 letters) that were treated with
subcutaneous injections of 5 mg of the
4-{(S)-2-[(S)-2-methoxycarbonyl-amino)-3-phenylpropanamido]-2-[-
2-(thiophen-2-yl)thiazol-4-yl]ethyl}phenylsulfamic acid twice a day
for 28 days. Improvement of visual acuity in these subjects was
observed for a period of two months (days 28 through 84). At any
time during the course of the study, investigators could administer
additional therapy consisting of intravitreal injection of an
anti-VEGF agent, for example, ranibizumab, bevacizumab and/or
aflibercept, if considered by the investigator to be medically
necessary. Retinal thickness as measured by ocular coherence
tomography and best corrected visual acuity as measured by a
standard vision test (ETDRS) were assessed at regular intervals
during the 28 day active treatment phase and through the 2 month
post-treatment observation phase, (Screening, Day 1 [baseline], Day
7, Day 14, Day 21, Day 28, Day 42, Day 56 and Day 84). The main
efficacy outcomes for the study were change in CRT and visual
acuity over time with treatment.
[1466] FIG. 1 depicts the results of two phase three studies to
determine the effect of intravitreal injections of ranibizumab in
patients with diabetic macular edema. In this study patients
received intravitreal injections with either 0.3 mg
(.diamond-solid.) or 0.5 mg (.box-solid.) ranibizumab monthly,
whereas the control group (.tangle-solidup.) received placebo. As
depicted in FIG. 1 the reduction in Central Foveal Thickness (CFT)
for both the 0.3 mg and 0.5 mg cohorts were essentially identical.
As shown in FIG. 1, the two groups receiving ranibizumab had a
reduction in Central Foveal Thickness of approximately 120 to 160
.mu.m from day 7 to 1 month after the first injection of
ranibizumab.
[1467] FIG. 2 depicts the results of a study wherein 4 patients
received 5 mg of the
4-{(S)-2-[(S)-2-methoxycarbonylamino)-3-phenylpropanamido]-2-[2-
-(thiophen-2-yl)thiazol-4-yl]ethyl}phenylsulfamic acid
subcutaneously twice daily for 28 days and subsequently were
treated in one or both eyes (7 eyes total) with either ranibizumab
(0.3 or 0.5 mg) or aflibercept (2 mg) by intravitreal injection at
the discretion of the study investigator. FIG. 2 is read in this
manner: 1 patient eye had a Central Foveal Reduction of between
50-100 .mu.m, 1 patient eye had a Central Foveal Reduction of
between 150-200 .mu.m, 1 patient eye had a Central Foveal Reduction
of between 200-250 .mu.m, 1 patient eye had a Central Foveal
Reduction of between 300-350 .mu.m, 2 patient eyes had a Central
Foveal Reduction of between 350-400 .mu.m, and 1 patient eye had a
Central Foveal Reduction of between 450-500 .mu.m at 14-28 days
post ranibizumab or aflibercept. The mean change in Central Foveal
Thickness was -289 .mu.m, approximately double the reduction seen
after ranibizumab injection in the study in FIG. 1.
[1468] FIG. 3 depicts the results of two phase three studies
performed to determine the effect of intravitreal injections of
ranibizumab in patients with diabetic macular edema. Results of
these studies were used to determining the effectiveness of the
disclosed methods for treating ocular diseases. The control group
is represented by (.diamond-solid.). Patients receiving 0.5 mg of
ranibizumab monthly via ocular injection are represented by
(.box-solid.). As shown in FIG. 3, the group receiving ranibizumab
had an increase in visual acuity of between approximately 4 to 6
letters from day 7 to 1 month after the first injection of
ranibizumab.
[1469] FIG. 4 depicts the increased visual acuity of a study
wherein 4 patients received 5 mg of the
4-{(S)-2-[(S)-2-methoxycarbonylamino)-3-phenylpropanamido]-2-[2-(thiophen-
-2-yl)thiazol-4-yl]ethyl}phenylsulfamic acid subcutaneously twice
daily for 28 days and subsequently were treated with either
ranibizumab (0.3 or 0.5 mg) or aflibercept (2 mg) by intravitreal
injection at the discretion of the study investigator. FIG. 4 is
read in this manner: 1 patient eye had an increase of from 16 to 18
letters improvement, 2 patient eyes had an increase of from 14 to
16 letters improvement, 1 patient eye had an increase of from 10 to
12 letters improvement, 1 patient eye had an increase of from 6 to
8 letters improvement, 1 patient eye had an increase of from 2 to 4
letters improvement, and 1 patient eye had a decrease of from 2 to
4 letters at 14-28 days post ranibizumab or aflibercept. The mean
change in Visual Acuity was 9 letters, approximately 3 to 5 letters
more improvement than seen in the benchmark study of ranibizumab
alone depicted in FIG. 3.
[1470] FIG. 5 represents the results of a single patient. The eye
having the greater Central Foveal Thickness was chosen as the Study
Eye. The patient from day one was given 5 mg of the
4-{(S)-2-[(S)-2-methoxycarbonylamino)-3-phenylpropanamido]-2-[2-(thiophen-
-2-yl)thiazol-4-yl]ethyl}phenylsulfamic acid subcutaneously twice
daily. At week 3 (21 days, indicated by arrow) the fellow eye was
treated with 0.5 mg of ranibizumab by injection. At week 6 (42
days, indicated by arrow) the treated eye was treated with 0.5 mg
of ranibizumab. As seen in FIG. 5, the Central Foveal Thickness of
the fellow eye fell significantly (350 .mu.m) by week 4 (28 days).
As a result, there was a pronounced reduction in CFT in the study
eye from day 21 to day 28 (approximately 250 .quadrature.m). As
seen in FIG. 5, by the next monitoring point, week 6, the effects
of the systemically received ranibizumab were no longer present and
the CFT returned to approximately 775 .mu.m. At week 6, the study
eye was treated with an intravitreal injection of 0.5 mg of
ranibizumab. As depicted in FIG. 5, by week 8, there was an overall
reduction in CFT of approximately 500 .mu.m, wherein the CFT of the
subject eye was approximately 225 .mu.m. Compared to the study
depicted in FIG. 1 wherein the average change in CFT at one month
after ranibizumab injection was approximately 160 mm, the
combination disclosed method provided substantially greater
reductions at 2-4 weeks following ranibizumab injection.
[1471] FIG. 6 represents the results of a single patient. The eye
having the greater Central Foveal Thickness was chosen as the Study
Eye. The patient from day one was given 5 mg of the
4-{(S)-2-[(S)-2-methoxycarbonylamino)-3-phenylpropanamido]-2-[2-(thiophen-
-2-yl)thiazol-4-yl]ethyl}phenylsulfamic acid subcutaneously twice
daily. At week 4 (28 days, indicated by arrow) the fellow eye was
rescued with 2 mg of aflibercept. After rescue, the Fellow eye had
a CFT reduction of approximately 400 .mu.m. At week 6 (42 days,
indicated by arrow) the study eye was rescued with 2 mg of
aflibercept. After rescue, the Study eye had a CFT reduction of
approximately 300 .mu.m. Unlike the results depicted for the
ranibizumab protocol, there was no evidence of systemically
delivered aflibercept to the Fellow Eye. From onset of the study,
there was a reduction of CFT in the study eye and non-treated eye
of approximately 300 .mu.m and 280 .mu.m respectively.
[1472] FIG. 7 graphically represents the results of a choroidal
neovascularization murine test involving an active control,
aflibercept (Eylea.TM.), the
4-{(S)-2-[(S)-2-methoxycarbonylamino)-3-phenylpropanamido]-2-[2-(thiophen-
-2-yl)thiazol-4-yl]ethyl}phenylsulfamic acid and a combination of
aflibercept and the
4-{(S)-2-[(S)-2-methoxycarbonylamino)-3-phenylpropanamido]-2-[2-(thiophen-
-2-yl)thiazol-4-yl]ethyl}phenylsulfamic acid. Rupture of Burch's
membrane in three locations of the eye was induced by standard
laser methods (see, Tobe T et al., "Targeted Disruption of the FGF2
Gene Does Not Prevent Choroidal Neovascularization in a Murine
Model," Am. J. Pathology, Vol. 153, No. 5, (1998)). Control animals
were given intraocular injections of phosphate buffered saline
(PBS), animals treated with aflibercept received one intraocular 40
.mu.g of the drug on the day of laser treatment. The mice were then
treated with either the
4-{(S)-2-[(S)-2-methoxycarbonylamino)-3-phenylpropanamido]-2-[2-(thiophen-
-2-yl)thiazol-4-yl]ethyl}phenylsulfamic acid at 20 mg/kg by
subcutaneous injections twice daily or PBS injections twice daily.
This yielded four groups of mice; a negative control group treated
with intraocular and subcutaneous PBS, a monotherapy group treated
with intraocular aflibercept and subcutaneous PBS, a monotherapy
group treated with intraocular PBS and subcutaneous injections of
the
4-{(S)-2-[(S)-2-methoxycarbonylamino)-3-phenylpropanamido]-2-[2-(thiophen-
-2-yl)thiazol-4-yl]ethyl}phenylsulfamic acid and a combination
therapy group receiving one intraocular injection of 40 .mu.g of
the drug on the day of laser treatment and 20 mg/kg subcutaneous
injections twice daily.

Plasma Concentration in Human Test Subjects.
[1478] FIG. 9 depicts the mean plasma concentration over time after
a single dose of a 5 mg, a 15 mg, a 22.5 mg, or a 30 mg of a test
compound on day 14, respectively, in a multiple ascending dose
study in patients with diabetic macular edema. The concentration
time curves are consistent with rapid absorption and elimination of
test compound with rapid Tmax (range 0.2 to 1.0 hours) and short
elimination half-life (range 0.6 to 1.5 hours). The overall
exposures were approximately dose proportional with Cmax ranging
from approximately 40-430 ng/ml and AUC ranging from approximately
70-920 nghr/ml at 5-30 mg dose.

Phase 1B/2A Clinical Trial.
[1479] A phase 1B/2A open-label, Multiple-ascending dose cohort
study to assess the pharmacokinetics and pharmacodynamics effect of
28-day repeat subcutaneous dose of
4-{(S)-2-[(S)-2-(methoxycarbonylamino)-3-phenylpropanamido]-2-[2-(thiophe-
n-2-yl)thiazol-4-yl]ethyl}phenylsulfamic acid (drug) in subjects
with diffuse diabetic macular edema (DME).
[1480] The aim of this study was to evaluate tolerability, safety,
efficacy and pharmacokinetics and pharmacodynamics in patients with
DME involving the center of the fovea with central subfield mean
thickness .gtoreq.325 .mu.m measured by spectral domain-optical
coherence tomography (SD-OCT).
[1481] Twenty-four patients were administered ascending doses of
test compound twice daily (BID) for 28 days in 4 separate cohorts
at 5, 15, 22.5 or 30 mg BID, respectively. Drug was supplied as a
lyophilized powder in a vial for reconstitution. Each vial
contained 100 mg drug and 250 mg HP.beta.CD. Vials were
reconstituted with sterile 5% dextrose for cohort 1 (5 mg BID) and
with sterile diluent containing 5% HP.beta.CD/1% dextrose for
cohorts 2, 3, and 4 (15 mg, 22.5 mg and 30 mg BID).
[1482] For cohorts 1 (5 mg BID) and 2 (15 mg BID) the volume
administered for each dose was 0.5 ml (10 and 30 mg/ml,
respectively) and for cohorts 3 and 4 the volume was 0.75 ml (30
and 40 mg/ml, respectively).
[1483] Blood samples for pharmacokinetic profiling were taken
pre-dose(0), 15 minutes, 1 hour, 2 hours, 3 hours and 4 hours after
administration of the first dose on day 14.
[1484] Plasma drug concentration was determined with a validated
LC/MS-MS method. The pharmacokinetic (PK) parameters were
determined using a standard non-compartmental method, and Cmax,
AUC.sub.last (with last being from time 0 to the last quantifiable
point), AUCinf, were analyzed statistically using log-transformed
data. The dose proportionality 90% confidence intervals were
calculated from the mean.
