Abstract

The present invention relates to novel crystalline forms of (R)—N—((S)-1-(4-(3,3-dimethyl-2-oxoindolin-1-yl)piperidin-1-yl)-1-oxo-4-phenylbutan-2-yl)piperidine-3-carboxamide hydrochloride (HCl-salt), and to pharmaceutical compositions thereof, process for preparation or isolation of such crystalline forms and compositions, and to methods of using such crystalline forms and compositions in the treatment of various diseases or disorders which are mediated by motilin receptor activity.

Claims (13)

7 . The (R)—N-((S)-1-(4-(3,3-dimethyl-2-oxoindolin-1-yl) piperidin-1-yl)-1-oxo-4-phenylbutan-2-yl) piperidine-3-carboxamide HCl Crystalline Form B according to claim 5 , further characterized by a differential scanning calorimetry (DSC) thermogram exhibiting an endothermic onset temperature of 258+1° C.

8 . A pharmaceutical composition comprising (R)—N-((S)-1-(4-(3,3-dimethyl-2-oxoindolin-1-yl) piperidin-1-yl)-1-oxo-4-phenylbutan-2-yl) piperidine-3-carboxamide HCl Crystalline Form A according to claim 1 , together with one or more pharmaceutically acceptable carriers or excipients.

9 . The pharmaceutical composition according to claim 8 , wherein the composition is a dosage form for oral, parenteral, topical, rectal, intravaginal, ocular, or aural administration.

10 .
