Further evidence has come to light suggesting that GlaxoSmithKline knew about an increased cardiac risk with the diabetes drug rosiglitazone (Avandia) as early as 2001 but withheld the data and that certain officials at the FDA conspired with the company to minimize the impact of later safety results.

Spark Therapeutics and Pfizer Inc. announced that the U.S. Food and Drug Administration (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 Phase 1/2 trial as a potential one-time therapy.
