How Will Beqvez Fare in Challenging Market for Cell and Gene Therapies?

The FDA recently approved the second gene therapy for hemophilia B, Pfizer Inc.’s Beqvez (fidanacogene elaparvovec-dzkt). While the agent offers an additional treatment option with the potential for freedom from regular infusions of factor therapy, its price — which is equal to that of its competitor — may be too high for many payers, according to a Zitter Insights survey. Industry experts say that it may suffer from some of the challenges other cell and gene therapies have faced in gaining a foothold in the U.S. market.

On April 25, the FDA approved Beqvez for the treatment of adults with moderate to severe hemophilia B who use factor IX prophylaxis therapy; have current or historical life-threatening hemorrhage; or have repeated, serious spontaneous bleeding episodes and do not have neutralizing antibodies to adeno-associated virus (AAV) serotype Rh74var (AAVRh74var) capsid as detected by an FDA-approved test. The manufacturer launched a warranty program for the intravenous infusion based on durability of patient response to treatment.
