Abstract
The present disclosure relates to crystalline polymorph and amorphous forms of 2-methyl-2-(3-methyl-4-(4-(methylamino)-5-(trifluoromethyl)pyrimidin-2-ylamino)-1H-pyrazol-1-yl)propanenitrile or solvates, tautomers, and pharmaceutically acceptable salts or cocrystals thereof, and processes for their preparation.
Claims25
A pharmaceutical composition comprising a therapeutically effective amount of a crystalline polymorph of 2-methyl-2-(3-methyl-4-(4-(methylamino)-5-(trifluoromethyl)pyrimidin-2-ylamino)-1H-pyrazol-1-yl)propanenitrile, and a pharmaceutically acceptable carrier, glidant, diluent, or excipient, wherein the crystalline polymorph is selected from:
