- UGN-102 demonstrated 82.3% duration of response (DOR) at 12 months in patients who achieved complete response at 3 months
- 79.6% complete response rate at 3 months in patients treated with UGN-102
- Safety profile consistent with prior clinical trials of UGN-102
Reno, Nevada (UroToday.com) -- UroGen Pharma Ltd. (Nasdaq: URGN), a biotech company dedicated to developing and commercializing innovative solutions that treat urothelial and specialty cancers, today announced the presentation of the Phase 3 ENVISION trial’s efficacy and safety results at the Society of Urologic Oncology (SUO) annual meeting in Dallas, TX. These results, published online in the Journal of Urology in October, demonstrate that treatment with investigational therapy UGN-102, a mitomycin-based intravesical solution, resulted in a high and clinically meaningful complete response rate that was durable in patients with recurrent low-grade intermediate-risk non-muscle-invasive bladder cancer (LG-IR-NMIBC).
"Finding options for patients with recurrent low-grade bladder cancer continues to be a major unmet need,” says Max Kates, R. Christian B. Evensen Professor and an Associate Professor of Urology and Oncology, and Director, Division of Urologic Oncology at the Brady Urological Institute at Johns Hopkins and ENVISION study investigator. “We are excited by the overall results of the ENVISION trial, especially the durability of response data, that support the potential of UGN-102 as a viable treatment option for these patients."
In the ENVISION study, UGN-102 treatment showed an impressive 82.3% (95% CI: 75.9%, 87.1%) duration of response (DOR) at 12 months, according to the Kaplan-Meier estimate, in patients who achieved a complete response (CR) at 3 months following the initial treatment with UGN-102. The DOR at 15 months (n=43) and 18 months (n=9) remained robust, both at 80.9% (95% CI: 73.9%, 86.2%) according to the Kaplan-Meier estimates. These results build upon the trial’s positive primary endpoint, a 79.6% (95% CI: 73.9%, 84.5%) CR rate 3 months after the first instillation of UGN-102.
The side effect profile of UGN-102 was consistent with previous clinical trials, further supporting its potential as a new treatment option for patients with LG-IR-NMIBC.
"We are excited by the progress made in advancing UGN-102 as a potential treatment for LG-IR-NMIBC and securing a PDUFA goal date of June 13, 2025, from the FDA,” said Mark Schoenberg, M.D., Chief Medical Officer, UroGen. “The strong durability of response observed in the ENVISION study highlights UGN-102’s promising potential for patients. Given that many LG-IR-NMIBC patients are elderly and endure multiple surgeries under general anesthesia for their condition that impact their health and quality of life, there is an urgent need for alternative treatment options that can prolong recurrence-free periods and enhance patient outcomes."The most common treatment-emergent adverse events (TEAEs) in the ENVISION trial were dysuria, hematuria, urinary tract infection, pollakiuria, fatigue, and urinary retention. TEAEs were typically mild-to-moderate in severity and resolved or resolving. The ENVISION trial demonstrated a similar safety profile to that observed in other studies of UGN-102.
