About Bomedemstat (IMG-7289)

Bomedemstat is being evaluated in an open-label Phase 2 clinical trial for the treatment of advanced myelofibrosis (MF), a bone marrow cancer that interferes with the production of blood cells. (Read more…) MF patients who are resistant to, intolerant of, or ineligible for a Janus Kinase (JAK) inhibitor are eligible for the study of bomedemstat as monotherapy. The endpoints include spleen volume reduction and symptom improvement at 12 and 24 weeks of treatment. Preliminary results were most recently presented at the 2020 European Hematology Association. In addition to the MF study, bomedemstat is also being evaluated for the treatment of essential thrombocythemia and polycythemia vera.

Bomedemstat is an orally available small molecule discovered and developed by Imago BioSciences that inhibits lysine-specific demethylase 1 (LSD1 or KDM1A), an enzyme shown to be vital in cancer stem/progenitor cells, particularly neoplastic bone marrow cells. In non-clinical studies, bomedemstat demonstrated robust in vivo anti-tumor efficacy across a range of myeloid malignancies as a single agent and in combination with other chemotherapeutic agents. Bomedemstat is an investigational agent currently being evaluated in multiple ongoing clinical trials (ClinicalTrials.gov Identifier: NCT03136185, NCT04262141, NCT04254978 and NCT04081220). Bomedemstat has U.S. FDA Orphan Drug and Fast Track Designation for the treatment of myelofibrosis and essential thrombocythemia, Orphan Drug Designation for treatment of acute myeloid leukemia and PRIME designation by the European Medicines Agency for the treatment of MF.
