Abstract
Crystalline forms of the p38 kinase inhibitor N-(2-hydroxyacetyl)-5-(4-piperidyl)-4-(4-pyrimidinyl)-3-(4-chlorophenyl)pyrazole are provided. These crystalline forms include (a) a first anhydrous crystalline form possessing improved physical stability relative to other solid-state forms of the compound; (b) a second anhydrous crystalline form possessing unique properties relative to other solid-state forms of the compound; (c) a third anhydrous crystalline form possessing unique properties relative to other solid-state forms of the compound; and (d) solvated crystalline forms, hydrated crystalline forms, and crystalline salt forms of the compound that are useful, for example, as intermediate solid-state forms in the preparation of other crystalline forms of the compound. Also provided are combinations and pharmaceutical compositions comprising at least one of these crystalline forms, processes for preparing these crystalline forms and for preparing compositions comprising these crystalline forms, and methods for the prophylaxis and/or treatment of a p38 kinase-mediated condition comprising administering to a subject a therapeutically effective amount of at least one of these crystal…
