INREBIC (fedratinib hydrochloride) is an oral JAK2-selective tyrosine kinase inhibitor approved in August 2019 for treatment of high-risk primary myelofibrosis and secondary myelofibrosis (post-polycythemia vera and post-essential thrombocythemia). The drug works by inhibiting JAK2 and FLT3, reducing phosphorylation of STAT3/5 proteins, thereby blocking abnormal cell proliferation and inducing apoptosis in myeloproliferative neoplasms. In preclinical models, fedratinib demonstrated improved survival, reduced splenomegaly, improved blood counts, and reduced fibrosis progression.
2 (JAK2) and FMS-like tyrosine kinase 3 (FLT3). Fedratinib is a JAK2-selective inhibitor with higher inhibitory activity for JAK2 over family members JAK1, JAK3 and TYK2. Abnormal activation of JAK2 is associated with myeloproliferative neoplasms (MPNs), including myelofibrosis and polycythemia…
