Momelotinib

Momelotinib is a Janus Kinase 1 (JAK1) and 2 (JAK2) inhibitor. It is a competitive inhibitor of JAK ATP binding. First approved by the FDA on September 15, 2023, momelotinib is used to treat myelofibrosis. Myelofibrosis (MF) is a group of myeloproliferative neoplasms characterized by abnormal proliferative hematopoietic stem cells, leading to the release of cytokines and growth factors. MF includes primary MF (PMF), post-polycythemia vera (PV) MF, and post-essential thrombocythemia (ET) MF. Clinical manifestations of MF include anemia and thrombocytosis. Momelotinib works to block the JAK-signal transducer and activator of transcription (STAT) signalling pathway, which is aberrant in MF.

Momelotinib is indicated for the treatment of intermediate or high-risk myelofibrosis (MF), including primary MF or secondary MF [postpolycythemia vera (PV) and post-essential thrombocythemia (ET)], in adults with anemia.

• High risk Myelofibrosis
• Intermediate risk Myelofibrosis
