ImmunityBio, Inc. today announced Dr. Karim Chamie, Associate Professor of Urology at UCLA, will be presenting “Quality of life in QUILT 3.032 study: Patients with BCG-unresponsive non-muscle invasive bladder cancer (NMIBC) receiving IL-15R⍺Fc superagonist N-803 plus BCG” at the ASCO Genitourinary Cancers Symposium conference on February 16-18, 2023.

N-803 (Anktiva™), ImmunityBio’s lead cytokine fusion protein, is a novel IL-15 superagonist complex and has received Breakthrough Therapy and Fast Track Designations from the U.S. Food and Drug Administration (FDA) for BCG-unresponsive CIS NMIBC.

N-803 is currently under review by the FDA for this indication with a Prescription Drug User Fee Act target date of May 23, 2023.

Previously, on November 10, 2022, the peer-review journal NEJM Evidence published results from the QUILT 3.032 trial studying N-803 plus BCG in adults with NMIBC CIS with or without Ta/T1 papillary disease.

The published results demonstrate that in patients with BCG-unresponsive NMIBC CIS and papillary disease, BCG plus N-803 (referred to as NAI) CRs were achieved with the persistence of effect with a 90% probability of avoiding cystectomies in responders, a life-changing procedure of removing the bladder, and 100% bladder cancer-specific survival at 24 months.

“The peer review and publication of data in NEJM Evidence highlights the significance of the positive results of the QUILT 3.032 trial in patients with BCG-unresponsive NMIBC,” commented  Patrick Soon-Shiong, M.D., Executive Chairman and Global Chief Scientific and Medical Officer at ImmunityBio, in a press release on November 10, 222.

“These data further our understanding of N-803’s unique role in potentially boosting the proliferation of natural killer and T cells while synergistically enhancing BCG efficacy.”
