Imago BioSciences Preliminary Data from Ongoing Phase 2 Study of IMG-7289 for the Treatment of Myelofibrosis to be Presented at the 61st American Society of Hematology Annual Meeting & Exposition

SAN FRANCISCO, October 25, 2019 - Imago BioSciences, Inc., a clinical-stage biotechnology company focused on the treatment of myeloproliferative neoplasms (MPN) and related bone marrow diseases, announced today that preliminary data from its ongoing Phase 2 study of IMG-7289 (bomedemstat) in patients with myelofibrosis (MF) has been selected for an oral presentation at the American Society of Hematology (ASH) Annual Meeting, on December 9 in Orlando, Florida. The abstract will be published November 6, and the presentation will include results updated from those in the abstract.

Kristen Pettit, M.D., assistant professor at the University of Michigan and investigator in the study at the Rogel Cancer Center in Ann Arbor, will present both preliminary results from Phase 2a, as well as initial data from patients from the Phase 2b expansion. The objectives of the study are to evaluate the safety and efficacy of IMG-7289 (bomedemstat) in up to 75 patients at sites in Australia, the US, UK and Europe. In this study, bomedemstat is administered orally once-daily as monotherapy in adult patients with intermediate-2 or high-risk MF resistant to or intolerant of ruxolitinib.

“The FDA recently approved a second JAK2 inhibitor but the majority of patients with myelofibrosis will eventually lose the benefit of those treatments”, said Dr. Pettit. “Patients have an urgent need for new treatments that manage their symptoms. We continue to be encouraged by the bomedemstat data we see in this clinical investigation.”

About IMG-7289

IMG-7289 (bomedemstat), is a small molecule discovered by Imago BioSciences that inhibits lysine-specific demethylase 1 (LSD1 or KDM1A). LSD1 is an enzyme regulating both cytokine expression and myeloid differentiation and sustaining self-renewal in malignant hematopoietic stem/progenitor cells. In non-clinical studies, bomedemstat demonstrated robust in vivo efficacy as a single agent and in combination with other therapeutic agents across a range of myeloid malignancy models, including the myeloproliferative neoplasms encompassing myelofibrosis, essential thrombocythemia and polycythemia vera. The U.S. Food and Drug Administration (FDA) has granted Fast Track designation to bomedemstat for the treatment of myelofibrosis. An international Phase 2b study of bomedemstat for the treatment of myelofibrosis remains ongoing (Clinicaltrials.gov NCT03136185). Additional clinical studies in hematologic disorders will begin in 2020.
