Abstract
This disclosure relates to polymorphs of (7S,13R)-11-fluoro-7,13-dimethyl-6,7,13,14-tetrahydro-1,15-ethenopyrazolo[4,3-f][1,4,8,10]benzoxatriazacyclotridecin-4(5H)-one that are useful in the treatment of disease, such as cancer, in mammals. This disclosure also relates to compositions including such polymorphs, and to methods of using such compositions in the treatment of diseases, such as cancer, in mammals, especially in humans.
