Development of UGN-301 (zalifrelimab) to discontinue following completion of Ph 1 dose escalation study
UroGen has made the strategic decision to discontinue development of UGN-301 (zalifrelimab) following completion of its Phase 1 dose escalation study. While the study confirmed proof of concept for RTGel® as a viable platform for local delivery of complex immunotherapies, UGN-301’s overall clinical profile did not meet UroGen’s internal benchmarks for advancement to Phase 2. The program achieved key proof of concept objectives, including sustained bladder exposure with minimal systemic absorption and was generally well tolerated, demonstrating the ability to mitigate CTLA-4–related toxicities, and encouraging efficacy signals. These findings further reinforce the versatility and potential of RTGel technology to enable localized delivery of immunotherapy candidates.
