Adstiladrin (nadofaragene firadenovec-vncg) suspension approved for intravesical use

Ferring Pharmaceuticals today announced the U.S. Food and Drug Administration (FDA) approved Adstiladrin® (nadofaragene firadenovec-vncg), a novel adenovirus vector-based gene therapy, for the treatment of adult patients with high-risk, Bacillus Calmette-Guérin (BCG)-unresponsive non-muscle invasive bladder cancer (NMIBC) with carcinoma in situ (CIS) with or without papillary tumors.

Bladder cancer is the sixth most common cancer in the U.S., with NMIBC representing approximately 75% of all new bladder cancer cases. BCG remains the first-line standard of care for people living with high-grade NMIBC. However, more than 50% of patients who receive initial treatment with BCG will experience disease recurrence and progression within one year, with many developing BCG-unresponsive disease.

Adstiladrin, an intravesical therapy administered every three months, targets the patient’s own bladder wall cells to enhance the body’s natural defenses to fight cancer. The FDA approval was based on results of the Phase 3 clinical trial, which met its primary endpoint with more than half (51%, n=50 of 98; 95% CI 41 to 61) of patients with carcinoma in situ with or without concomitant high-grade Ta or T1 disease (CIS ± Ta/T1) achieving a complete response (CR) by three months. Of the patients who achieved an initial CR, 46% (n=23 of 50) continued to remain free of high-grade recurrence at 12 months.
