UroGen Submits NDA for UGN-103, an Investigational Treatment of Recurrent LG-IR-NMIBC

About this update from Urogen Pharma Ltd.

PRINCETON, N.J., Aug. 17, 2026 (GLOBE NEWSWIRE) -- UroGen Pharma Ltd. (Nasdaq: URGN), a biotech company dedicated to developing and commercializing innovative solutions that treat urothelial and specialty cancers, today announced the submission of a New Drug Application (NDA) to the U.S. Food and Drug Administration (FDA) for its investigational drug UGN-103 (mitomycin) for intravesical solution. UGN-103 is a next-generation mitomycin formulation being developed for the treatment of adults with recurrent low-grade intermediate-risk non-muscle invasive bladder cancer (LG-IR-NMIBC). It is built on the clinical and commercial foundation of ZUSDURI (mitomycin) for intravesical solution. "The NDA submission for UGN-103 marks another important milestone in advancing our vision to redefine the treatment of urothelial cancers," said Liz Barrett, President and CEO of UroGen. "UGN-103 represents the next evolution in our portfolio and is designed to provide a more streamlined manufacturing process, simplified reconstitution and extended shelf-life of the reconstituted product while leveraging our RTGel® technology." The NDA for UGN-103 is supported by the clinical data from the ongoing Phase 3 UTOPIA trial, a single-arm, multicenter study evaluating the efficacy and safety of UGN-103 in adult patients with recurrent LG-IR-NMIBC. UGN-103 demonstrated a 77.8% three-month complete response (CR) rate (95% CI: 68.3%, 85.5%) and a 94.5% six-month duration of response (DOR) by Kaplan-Meier estimate (95% CI: 86.1%, 97.9%). Both the three-month CR rate and the DOR observed at six months with UGN-103 in the UTOPIA trial are consistent with those observed in the pivotal ENVISION trial of ZUSDURI. Because these findings are derived from separate clinical studies, no formal cross-trial comparison was performed. About UGN-103In January 2024, UroGen entered into a licensing and supply agreement with medac to develop UGN-103 for recurrent LG-IR-NMIBC. UGN-103 is designed to reinforce and build on the clinical and commercial foundation of ZUSDURI, the first and only FDA-approved treatment for adults with recurrent LG-IR-NMIBC. The program maintains UroGen's innovative and proven RTGel technology, enabling sustained mitomycin exposure in the bladder, while incorporating next-generation enhancements, including a more streamlined manufacturing process and simplified reconsti...
