Spark Therapeutics (ONCE) and Pfizer Inc. (PFE) announced today that the U.S. FDA has granted breakthrough therapy designation to SPK-9001, the lead investigational candidate in the companies’

SPK-FIX program, in development for the treatment of hemophilia B. SPK-9001, a novel bio-engineered adeno-associated virus (AAV) capsid expressing a codon-optimized, high-activity human factor IX variant, is being investigated in an ongoing P1/2 trial as a potential one-time therapy.

 

The Bottom Line: Breakthrough therapy designation is intended to expedite the development and FDA review of drugs to treat a serious or life-threatening disease or condition. The designation requires preliminary clinical evidence that the investigational therapy may offer substantial improvement over existing therapies on at least one clinically significant endpoint.
