ImmunityBio, Inc. announced new clinical study results demonstrating that treatment with ANKTIVA® (nogapendekin alfa inbakicept-pmln) in combination with Bacillus Calmette-Guérin $(BCG)$ shows a 96% bladder cancer-specific survival rate at three years in patients with BCG-unresponsive high-grade papillary-only non-muscle invasive bladder cancer (NMIBC). The findings, published in the January 2026 edition of The Journal of Urology, also indicate favorable outcomes in disease-free survival, progression-free survival, and high rates of cystectomy avoidance, with the median to cystectomy not yet reached. Safety data revealed a 3% incidence of grade 3 treatment-related adverse events, with no grade 4 or 5 events reported. ANKTIVA is currently approved in the U.S., U.K., and has conditional marketing authorization in the EU for BCG-unresponsive NMIBC with carcinoma in situ, with or without papillary tumors.
