FDA approves an expanded indication for nogapendekin alfa inbakicept-pmln for BCG-unresponsive non-muscle invasive bladder cancer
On October 14, 2026, the FDA expanded approval of nogapendekin alfa inbakicept-pmln (Anktiva, Altor BioScience, an ImmunityBio subsidiary) with BCG to cover adults with BCG-unresponsive non-muscle invasive bladder cancer with high-grade papillary-only tumors, beyond the prior indication limited to carcinoma in situ. The agency extrapolated efficacy from Cohort A of QUILT-3.032, a single-arm trial of 77 patients, which showed a complete response rate of 62%. The recommended dose is 400 mcg intravesically with BCG weekly for 6 weeks induction, followed by maintenance for up to 37 months.
