Imago BioSciences, Inc. announced that the first participant has been dosed in an investigator-sponsored Phase 1 study of bomedemstat, an investigational oral lysine-specific demethylase 1 (LSD1) inhibitor, in combination with venetoclax (Venclexa®) in patients with relapsed or refractory acute myeloid leukemia (AML). Venetoclax is a BCL-2 inhibitor approved by the U.S. Food and Drug Administration (FDA) for treatment of several hematologic cancers, including in combination with azacytidine for elderly patients with AML unable to tolerate the standard of care. The Phase 1 open-label study is being conducted at the University of Miami, led by Terrence J. Bradley, M.D. It will enroll approximately 18 adult participants diagnosed with AML who have failed at least one standard, front-line therapy and will assess the safety and efficacy of bomedemstat in combination with venetoclax (VenBom therapy). This combination regimen consists of once daily, oral administration of both bomedemstat and venetoclax.

Participants will receive three cycles of the treatment, and may continue to receive treatment as long as they experience clinical benefit or until disease progression.
