Fedratinib
Fedratinib
Chemical compound
Fedratinib, sold under the brand name Inrebic, is an anti-cancer medication used to treat myeloproliferative diseases including myelofibrosis.[5] It is used in the form of fedratinib hydrochloride capsules that are taken by mouth. It is a semi-selective inhibitor of Janus kinase 2 (JAK-2).[5][6] It was approved by the FDA on 16 August 2019.[5]
Myelofibrosis is a myeloid cancer associated with anemia, splenomegaly, and constitutional symptoms. Patients with myelofibrosis frequently harbor mutations which activate the JAK-STAT signaling pathway and which are sensitive to fedratinib. Phase I trial results focused on safety and efficacy of fedratinib in patients with high- or intermediate-risk primary or post–polycythemia vera/essential thrombocythemia myelofibrosis have been published in 2011.[7]
