ImmunityBio Provides Updated Status of Biologics License Application (BLA) for VesAnktiva Plus BCG for Patients with BCG-Unresponsive Non-Muscle Invasive Bladder Cancer Carcinoma in Situ

Apr 1, 2022

CULVER CITY, Calif., April 1, 2022 – ImmunityBio, Inc. (NASDAQ: IBRX), a clinical-stage immunotherapy company, today announced that it has achieved a major milestone with over 80 subjects in the QUILT-3.032 study completing at least 12 months of follow-up as of January 14, 2022. All data for QUILT-3.032, which is studying VesAnktivaTM plus BCG in subjects with BCG-unresponsive non-muscle invasive bladder cancer carcinoma in situ (NMIBC CIS), have been locked and analyzed. The results continue to demonstrate a clinically meaningful benefit that is sustained. The BLA has been compiled and, following final quality review, is expected to be submitted to the U.S. Food and Drug Administration (FDA) this month. The FDA granted Fast Track Designation to the pivotal trial based on Phase I data. In December 2019, the FDA granted ImmunityBio Breakthrough Therapy Designation (BTD) based on interim Phase 2 data indicating the primary endpoint of the trial was already met.

“We are excited to announce that the comprehensive compilation of our BLA is essentially written,” said Patrick Soon-Shiong, M.D., Executive Chairman and Global Chief Scientific and Medical Officer at ImmunityBio. “With 71% of the participants in this study having a complete response and a median duration of response of 26.6 months, we believe we have a clinically meaningful therapeutic alternative for patients suffering from NMIBC in which the only option remaining is total cystectomy.”

How Can ImmunityBio Help You?

Solutions for Patients

Many cancer therapies, including radiation therapy, chemotherapy, CAR-T therapy, and B-cell immunotherapy, severely weaken the immune system—the human body’s most important natural disease-fighting weapon. But ImmunityBio creates targeted, personalized immunotherapies that are designed to strengthen the immune system and enable it to outsmart your disease.

Opportunities for Trial Investigators

The broad therapeutic potential and demonstrated safety of ImmunityBio’s immune-enhancing IL-15 superagonist Anktiva (N-803), engineered NK-92® cell-based therapies, and our next-generation adenovirus-vectored anti-cancer vaccines make them appealing therapeutics for testing by trial investigators who want to make a contribution to clinical cancer research. Interested clinicians and other are encouraged to contact ImmunityBio to find out how they may support discovery of future cancer treatments.

Tools for Research Scientists

Our NK-92® easy-to-maintain and highly cytotoxic natural killer cell line provides a versatile bioanalytical testing tool that can help researchers develop functional killing assays that are more consistent and reliable than donor blood and reporter gene assays.

ImmunityBio is continuously pursuing new immunotherapies designed to attack disease by enhancing the patient’s immune system, not weakening it.
