Forma Therapeutics Announces Four Oral and Poster Presentations on FT-4202 in Sickle Cell Disease at Upcoming 2020 ASH Virtual Annual Meeting

Updated data from an ongoing randomized, multi-center, placebo-controlled Phase 1 clinical trial of FT-4202 in sickle cell disease selected for an oral presentation

WATERTOWN, Mass.--(BUSINESS WIRE)--Nov. 4, 2020-- Forma Therapeutics Holdings, Inc. (Nasdaq: FMTX), a clinical-stage biopharmaceutical company focused on rare hematologic diseases and cancers, today announced that four abstracts – including one oral presentation and three poster presentations – have been accepted for presentation at the 62nd American Society of Hematology (ASH) Virtual Annual Meeting taking place December 5-8, 2020.

The oral presentation will feature clinical data from the multiple ascending dose cohort of a randomized, multi-center, placebo-controlled Phase 1 trial of FT-4202 in people living with sickle cell disease (SCD). While the trial is currently enrolling patients in the second dose escalation cohort of 600 mg FT-4202 daily, data will be presented on 9-12 patients who have completed the 300 mg FT-4202 daily cohort. A “Trials in Progress” poster presentation will highlight key aspects of the planned registrational Phase 2/3 clinical trial. In addition, two collaborative posters will report the findings of research of FT-4202 in a mouse model of sickle cell anemia and in an ex vivo analysis of blood samples from patients with SCD, respectively.

“We’re pleased the FT-4202 data have been selected for multiple presentations at ASH 2020,” said Frank Lee, president and chief executive officer of Forma. “Forma has a deep commitment to advancing science in sickle cell disease. We look forward to sharing data that will further characterize FT-4202 as an investigational treatment for people living with sickle cell disease.”

The abstracts, currently available on the ASH conference website, are:

About Sickle Cell Disease

Sickle cell disease (SCD) is one of the most common disorders caused by a single gene mutation. Prevalence of SCD is approximately 100,000 people in the U.S. and approximately 30,000 people in France, Germany, Italy, Spain and the UK. While reporting limitations complicate stating an exact number, the National Institutes of Health reports that prevalence is estimated at over 20 million individuals worldwide. In people living with SCD, red blood cells, or RBCs, spontaneously deform in low oxygen conditions, taking on a sickle-like shape. Sickle cells are stiff and have damaged membranes, causing the RBCs to clump and burst in small blood vessels, resulting in inflammation and vaso-occlusive crises. Repeated deformation also depletes the RBC energy supply, called ATP. One important consequence of this energy depletion is increased levels of a metabolite, 2,3-DPG, that further reduces the RBCs’ affinity for oxygen and exacerbates the cycle of repeated deformation and anemia.

About FT-4202

FT-4202 is a novel, oral, once-daily pyruvate kinase-R (PKR) activator designed to be a disease-modifying therapy for the treatment of sickle cell disease (SCD). Early studies and trials have shown that FT-4202 works upstream by employing a multi-modal approach and activating the red blood cells’ (RBC) natural PKR activity to decrease 2,3-DPG levels, which we believe leads hemoglobin to hold on to oxygen molecules longer to reduce RBC sickling. FT-4202 has also shown downstream activity by increasing ATP levels, the fuel that provides energy to cells, which we believe may improve RBC health and survival. Together, these effects have the potential to increase hemoglobin levels and decrease painful vaso-occlusive crises. In preclinical safety studies, FT-4202 did not inhibit aromatase activity, important biological processes responsible for sexual development.
