The U.S. FDA has approved the second hemophilia drug in nearly six months from Pfizer Inc.

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.

Pfizer also is shuttering its Oxbryta clinical studies and expanded access programs.
