Fedratinib – INREBIC® (USA)

According to the NCI website fedratinib hydrochloride is the monohydrate dihydrochloride salt form of fedratinib, an orally bioavailable, small-molecule, ATP-competitive inhibitor of Janus-associated kinase 2 (JAK2) and FMS-like tyrosine kinase 3 (FLT3; CD135; STK1; FLK2), with potential antineoplastic activity. Upon oral administration, fedratinib competes with wild-type JAK2 as well as mutated forms for ATP binding, which may result in inhibition of JAK2 activation, inhibition of the JAK-STAT signaling pathway, inhibition of tumor cell proliferation, and induction of tumor cell apoptosis. JAK2 is the most commonly mutated gene in bcr-abl-negative myeloproliferative disorders (MPDs). In addition, fedratinib targets, binds to and inhibits the activity of FLT3. This inhibits uncontrolled FLT3 signaling and results in the inhibition of proliferation in tumor cells overexpressing FLT3. FLT3, a class III receptor tyrosine kinase (RTK), is overexpressed or mutated in most B-lineage neoplasms and in acute myeloid leukemias and plays a key role in tumor cell proliferation. Check for active clinical trials using this agent. 

 

Indication according to the PDR:

  • For the treatment of intermediate-2 or high-risk primary or secondary (post-polycythemia vera or post-essential thrombocythemia) myelofibrosis.

NOTE: The FDA has designated fedratinib as an orphan drug for the treatment of primary or secondary myelofibrosis.
