After several delays, the interleukin-15 superagonist Anktiva (nogapendekin alfa inbakicept) from Immunitybio Inc. has been approved by the U.S. FDA for treating bladder cancer, specifically Bacillus Calmette-Guérin-unresponsive non-muscle-invasive bladder cancer with carcinoma in situ, with or without papillary tumors.
The U.S. FDA issued a complete response letter regarding the BLA for Immunitybio Inc.’s bladder cancer treatment, N-803 (Anktiva), halting the drug’s development and slicing the stock value in half. The problems stem from the FDA’s pre-license inspection of Immunitybio’s third-party contract manufacturing organizations, the company said. It said the FDA also had recommendations for specific chemistry, manufacturing and controls issues and assays that needed to be resolved before the BLA can be approved.
