Disc Medicine Inc. found itself after an end-of-phase II meeting with the U.S. FDA in what Wainwright analyst Douglas Tsao called a “best-case scenario” regarding the path forward for bitopertin in erythropoietic protoporphyria (EPP).
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.
Recordati SpA is shelling out $825 million up front for global rights to Enjaymo (sutimlimab), the only therapy approved for treating the rare disease cold agglutinin disease. In the deal with Sanofi SA, which won U.S. FDA approval of the antibody drug in 2022, the Italian pharma agreed to pay up to $250 million more should net sales reach certain thresholds.
The risk and benefit of Pfizer Inc.’s oral sickle cell disease drug Oxbryta (voxelotor) has flipped, prompted by what the company called new clinical data indicating “an imbalance in vaso-occlusive crises and fatal events” that need more study. Based on an EMA recommendation, Pfizer said it is voluntarily recalling all lots of Oxbryta from wherever it’s approved worldwide. Pfizer also is shuttering its Oxbryta clinical studies and expanded access programs.
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.
To be successful, CAR T-cells need a balance between being effective and overkill. Researchers from the University of Pennsylvania and Vittoria Biotherapeutics Inc. have eliminated the CD5 signaling pathway of their CAR Ts to prevent the immunosuppressive brake effect. In return, this improved their proliferation and antitumor activity in T cell lymphomas.
Samsung Bioepis Co. Ltd., of Incheon, South Korea, gained U.S. FDA approval of Epysqli (eculizumab-aagh) as the second biosimilar product to Alexion Pharmaceuticals Inc.’s Soliris (eculizumab) to treat two rare diseases. The regulatory clearance July 22 grants use of Epysqli to treat paroxysmal nocturnal hemoglobinuria and atypical hemolytic uremic syndrome – two rare hematologic- and kidney-related disorders known to affect about 50,000 and 5,000 patients in the U.S., respectively.
The U.S. Department of Health and Human Services’ Office of the Inspector General disclosed an advisory opinion finding Bluebird Bio Inc.’s fertility support program for a gene therapy treatment could run afoul of federal anti-kickback statutes. That follows a similar opinion against Vertex Pharmaceuticals Inc., and its fertility program associated with gene-editing therapy Casgevy (exagamglogene autotemcel). Vertex subsequently filed a lawsuit.
