SAN CARLOS, Calif.--(BUSINESS WIRE)-- Imago Biosciences, a clinical-stage pharmaceutical company developing novel anti-cancer therapies, announced today that the Phase 1/2a clinical trial of IMG-7289 for the treatment of high-risk acute myeloid leukemia (AML) and high-risk myelodysplastic syndrome (MDS) has fully enrolled at 45 patients. This study assessed the safety, pharmacokinetics, pharmacodynamics and anti-neoplastic activity of IMG-7289, an inhibitor of the epigenetic enzyme lysine-specific demethylase 1.

"We are extremely grateful to have worked with terrific investigators and staff that enrolled and cared for a population of patients in great need of therapeutic options," said Hugh Young Rienhoff, Jr. M.D., Imago’s Chief Executive Officer. "This study generated a wealth of knowledge about the pharmacokinetics, pharmacodynamics, and safety profile of our LSD1 inhibitor IMG-7289 as a single agent and in combination with ATRA. This study provides very clear guidance on how to use IMG-7289 at a variety of doses and in a variety of indications."

Upon the successful completion of the Phase 1 multiple ascending dose portion of the trial assessing IMG-7289 as a single agent, the study progressed into the Phase 2a expansion arm which evaluated the combination treatment regimen of IMG-7289 plus ATRA for extended dosing durations. Treatment of the final 2a expansion cohort remains ongoing.

About IMG-7289

IMG-7289 is a small molecule developed by Imago BioSciences that inhibits lysine-specific demethylase 1 (LSD1 or KDM1A), an enzyme regulating cytokine expression and shown to be vital in sustaining self-renewal in cancer stem/progenitor cells, particularly neoplastic bone marrow cells. In non-clinical studies, IMG-7289 demonstrated robust in vivo anti-tumor efficacy across a range of myeloid malignancies and models of myeloproliferative neoplasms as a single agent and in combination with other therapeutic agents. IMG-7289 also shows activity against solid tumors in combination with other agents in non-clinical models. IMG-7289 is an investigational agent currently being evaluated in a second Phase 1/2a clinical trial in high-risk myelofibrosis patients aged 18 or older is currently enrolling patients in both United States and Australia. ( Identifier NCT03136185).
