Description: CHZ868 or CHZ-868 is a potent and selective type II JAK inhibitor which demonstrates activity in JAK inhibitor persistent cells, murine MPN models, and MPN patient samples. CHZ868 showed significant activity in murine MPN models and induced reductions in mutant allele burden not observed with type I JAK inhibitors. CHZ868 stabilizes JAK2 in an inactive conformation. CHZ868 potently suppressed the growth of CRLF2-rearranged human B-ALL cells, abrogated JAK2 signaling, and improved survival in mice with human or murine B-ALL. CHZ868 and dexamethasone synergistically induced apoptosis in JAK2-dependent B-ALLs and further improved in vivo survival compared to CHZ868 alone. CHZ868 may be useful for patients with JAK2-dependent leukemias and other disorders.
