Ferring Pharmaceuticals A/S has notched another U.S. FDA approval, this time for a bladder cancer treatment, Adstiladrin (nadofaragene firadenovec). The non-replicating adenovirus vector-based gene therapy’s approval comes only weeks after the FDA’s Nov. 30 approval of the privately held company’s Rebyota (fecal microbiota, live), the first fecal microbiota treatment in the U.S. Adstiladrin is another landmark, as the first FDA-approved gene therapy to treat high-risk, non-muscle-invasive bladder cancer. Saint-Prex, Switzerland-based Ferring said it anticipates the product becoming commercially available in the U.S. in the second half of 2023.
