Biomea Fusion Inc.’s diabetes treatment produced enhanced glycemic control at week 26 courtesy of its 200-mg cohort. It’s the latest advance for the company’s candidate that also has strong prospects in treating leukemia. Top-line data from the ongoing phase II Covalent-111 study of BMF-219, a covalent menin inhibitor for regenerating insulin-producing beta cells, demonstrated that about 40% of participants, four of 11 patients, in the 200-mg cohorts showed a durable reduction, 1% or more, in the amount of blood sugar attached to the type 2 diabetes (T2D) patients’ hemoglobin. The data came from participants who had received the last dose in a four-week treatment.

The U.S. FDA has approved Novartis AG’s Fabhalta (iptacopan) as the first oral monotherapy for adults with paroxysmal nocturnal hemoglobinuria, a rare blood disease that impairs blood cell production. This is the only factor B inhibitor of the immune system’s complement pathway and is expected to be on the market before December ends. Fabhalta has plenty of competition from already-approved therapies and more treatments are in development.
