Momelotinib (CYT387) is an ATP-competitive small molecule that potently inhibits JAK1/JAK2 kinases. Momelotinib is developing by Gilead Sciences for the oral treatment of pancreatic and non-small cell lung cancers, and myeloproliferative disorders (including myelofibrosis, essential thrombocythaemia and polycythaemia vera).

Sample Use Guides

In Vivo Use Guide

150-300 mg/day. Maximum tolerated dose of momelotinib was found to be 300 mg/day in the phase I portion of a phase I/II study (NCT00935987) in patients with myelofibrosis. At the higher dose level of 400 mg/day, two of six patients experienced dose-limiting toxicities.

Route of Administration: Oral

In Vitro Use Guide

0.5 and 1.5 uM CYT387 caused growth suppression and apoptosis in JAK2-dependent hematopoietic cell lines, while nonhematopoietic cell lines were unaffected.
