Momelotinib (INN,^[1] formerly GS-0387, CYT-387) is an inhibitor of Janus kinases JAK1 and JAK2, acting as an ATP competitor with IC₅₀ values of 11 and 18 nM, respectively. The inhibitor is significantly less active towards other kinases, including JAK3 (IC₅₀ = 0.16 μM).^[2]

As of 2011, momelotinib is being developed as a drug for myelofibrosis and currently undergoes Phase I/II clinical trials. Additional potential treatment indications for momelotinib include other myeloproliferative neoplasms, cancer (solid and liquid tumors) and inflammatory conditions.^[3]

As of 2016, momelotinib is being investigated for primary myelofibrosis or post-polycythemia vera or post-essential thrombocythemia myelofibrosis (post-PV/ET MF),^[4] as well as a treatment for relapsed or refractory metastatic pancreatic ductal adenocarcinoma (in combination with capecitabine and oxaliplatin).^[5]

Discovery

The drug was originally discovered by Australian drug discovery company Cytopia, then developed by YM BioSciences Inc. (since acquired by Gilead Sciences as of 2013).
