At the recently concluded American Society of Hematology meeting, F Hoffmann-La Roche Ltd. presented promising results for their next-generation coagulation factor VIIIa (FVIIIa) mimetic bispecific antibody, NXT-007 (RO-7589655), supporting the ongoing phase I/II studies.
Although more and more gene therapies are getting the FDA stamp of approval, concerns persist about their potential long-term risks. U.S. lawmakers have proposed several pieces of legislation over the past few years to address some of the uncertainties. Now the Congressional Research Service (CRS) is suggesting other requirements Congress may want to consider to improve the regulatory landscape for gene therapies, especially those intended to treat blood disorders.
The first bispecific antibody to win regulatory approval is about to make a comeback 10 years after being taken off the market in Europe for commercial reasons. Catumaxomab, then called Removab, and now reborn with the brand name Korjuny, received a positive opinion for the treatment of malignant ascites from the EMA’s Committee for Medicinal Products for Human Use (CHMP,) at its monthly meeting Oct. 14 to 17.
The U.S. FDA has approved the second hemophilia drug in nearly six months from Pfizer Inc. This one, Hympavzi (marstacimab), is for preventing or reducing bleeding in those age 12 and older with hemophilia A and B. Hympavzi heralds a couple of market boundary breakers: it’s the first and only anti-tissue factor pathway inhibitor approved in the U.S. for hemophilia A or B and the first hemophilia medicine approved in the U.S. to be administered using a pre-filled, auto-injector pen.
For once, the EMA appears to have pipped the U.S. FDA to the post, with Pfizer Inc.’s hemophilia A and B therapy Hympavzi (marstacimab) recommended for approval in Europe on Sept. 20, while the U.S. PDUFA date is set for the fourth quarter of the year.
Metagenomi Inc. has reported data from an ongoing preclinical study designed to provide evidence supporting the potential durability and safety of the company’s hemophilia A gene editing investigational therapy, MGX-001.
Beijing Gensciences Inc. has developed a FVIIIa-mimetic bispecific antibody named SS-315 for the treatment of hemophilia A. SS-315 was developed by targeting FX with its upper Fab arms and FIXa with its down-side scFv arms, respectively; the hemostatic potential of SS-315 was investigated in vitro and in vivo.
Researchers from Poseida Therapeutics Inc. presented preclinical data for P-FVIII-101, a novel nonviral gene therapy being developed for the treatment of hemophilia A.
Positive data from Novo Nordisk A/S’s pivotal phase IIIa study of once-weekly and once-monthly doses of its hemophilia treatment, Mim8, are prompting the company to say it will submit the first regulatory approval request toward the end of this year. It could challenge Roche Holding AG’s Hemlibra (emicizumab), a bispecific factor IXa- and factor X-directed antibody for hemophilia A, that was approved in 2017 by the U.S. FDA.
Ending a late 2021 deal that was potentially worth billions, Moderna Inc. and Metagenomi Inc. are going their separate ways. The two had been collaborating on gene-editing R&D to develop therapies for treating serious genetic diseases. Moderna said it agreed with Metagenomi to end the deal as “Moderna continues to strategically prioritize its research and development investments.”
