CRYSTALLINE L-ARGININE SALT OF (R)-2-(7-(4-CYCLOPENTYL-3- (TRIFLUOROMETHYL)BENZYLOXY)-1,2,3, 4-TETRAHYDROCYCLO-PENTA [B]INDOL-3-YL)ACETIC ACID(COMPOUND1) FOR USE IN SIPI RECEPTOR-ASSOCIATED DISORDERS
First Claim
1. A method for treating an S1P1 receptor-associated disorder in an individual comprising administering to said individual in need thereof a therapeutically effective amount of a crystalline free-plate habit of L-arginine salt of (R)-2-(7-(4-cyclopentyl-3-(trifluoromethyl)benzyloxy)-1,2,3,4-tetrahydrocyclopenta[b]indol-3-yl)acetic acid;
- wherein said crystalline free-plate habit has a BET specific surface area of about 0.1 m2/g to about 5.0 m2/g.

Abstract
The present invention relates to, inter alia, a novel crystalline free-plate habit or morphology, processes for preparing the crystalline free-plate habit, and uses of the crystalline free-plate habit of the L-arginine salt of (R)-2-(7-(4-cyclopentyl-3-(trifluoromethyl)benzyloxy)-1,2,3,4-tetrahydrocyclo-penta[b]indol-3-yl)acetic acid (Compound 1) in the treatment of S1P1 receptor-associated disorders, for example, diseases and disorders mediated by lymphocytes, transplant rejection, autoimmune diseases and disorders, inflammatory diseases and disorders (e.g., acute and chronic inflammatory conditions), cancer, and conditions characterized by an underlying defect in the vascular integrity or that are associated with angiogenesis such as may be pathologic (e.g., as may occur in inflammation, tumor development, and atherosclerosis).

83. A method for preparing a crystalline free-plate habit of L-arginine salt of (R)-2-(7-(4-cyclopentyl-3-(trifluoromethyl)benzyloxy)-1,2,3,4-tetrahydrocyclopenta[b]indol-3-yl)acetic acid, said method comprising the steps of:
-
a) heating a first mixture comprising L-arginine salt of (R)-2-(7-(4-cyclopentyl-3-(trifluoromethyl)benzyloxy)-1,2,3,4-tetrahydrocyclopenta[b]indol-3-yl)acetic acid, a water-miscible anti-solvent, and water to a first heating temperature to form a second mixture; b) cooling said second mixture to a first cooling temperature followed by adding a first additional amount of said water-miscible anti-solvent to said second mixture while maintaining said first cooling temperature and thereafter heating to a second heating temperature to form a suspension; c) cycling Step b) optionally once or twice; and d) cooling said suspension to a second cooling temperature to form said crystalline free-plate habit of L-arginine salt of (R)-2-(7-(4-cyclopentyl-3-(trifluoromethyl)benzyloxy)-1,2,3,4-tetrahydrocyclopenta[b]indol-3-yl)acetic acid. - View Dependent Claims (84, 85, 89, 90, 91, 92, 93, 94, 95, 96, 97, 98, 99, 100)
