• Results from the pivotal Phase 3 ENVISION trial studying primary chemoablation with UGN-102 (mitomycin) for intravesical solution in patients with recurrent low-grade intermediate-risk non-muscle-invasive bladder cancer (LG-IR-NMIBC) will be presented as a late-breaking oral presentation

• The Phase 3 ATLAS trial comparing the efficacy and safety of intravesical chemoablation with UGN-102 with or without subsequent TURBT, to TURBT alone in patients with LG-IR-NMIBC will be presented in a digital poster session

UroGen Pharma Ltd. (Nasdaq: URGN), a biotech company dedicated to developing and commercializing novel solutions that treat urothelial and specialty cancers, will highlight data from two key Phase 3 trials evaluating UGN-102, an investigational treatment in development for LG-IR-NMIBC at the 2023 Society of Urologic Oncology (SUO) annual meeting, November 28-December 1 in Washington D.C. These data presentations further UroGen’s mission of developing and commercializing innovative treatments for urothelial and specialty cancers that provide patients with novel non-surgical options to fulfill the unmet needs that exist with current standards of care.

“The ATLAS and ENVISION Phase 3 clinical trials broaden our understanding of potentially using a new approach to treat LG-IR-NMIBC,” says Mark Schoenberg, M.D., Chief Medical Officer of UroGen. “We’re particularly excited that the SUO selected the ENVISION study as one of only two late-breaking trials designated for oral presentations, which we believe further reinforces its potential in advancing bladder cancer treatment. We are optimistic for what the future may hold for LG-IR-NMIBC patients who suffer from this highly prevalent and recurrent disease.”

About UGN-102

UGN-102 (mitomycin) for intravesical solution is an innovative drug formulation of mitomycin, currently in Phase 3 development for the treatment of LG-IR-NMIBC. Utilizing UroGen’s proprietary RTGel^® technology, a sustained release, hydrogel-based formulation, UGN-102 is designed to enable longer exposure of bladder tissue to mitomycin, thereby enabling the treatment of tumors by non-surgical means. UGN-102 is delivered to patients using a standard urinary catheter in an outpatient setting. Assuming positive findings from the durability of response endpoint from the ENVISION Phase 3 study, UroGen anticipates submitting an NDA for UGN-102 in 2024.

Forward-Looking Statements

This press release contains forward-looking statements as that term is defined in the Private Securities Litigation Reform Act of 1995, including, without limitation, statements regarding: the potential for UGN-102 to introduce a new non-surgical treatment option for LG-IR-NMIBC and advance bladder cancer treatment; optimism for the future of LG-IR-NMIBC patients; the anticipated release of durability of response endpoint data from the ENVISION Phase 3 study; UroGen’s plans to submit an NDA for UGN-102 and the expected timing thereof; and the potential of UroGen’s proprietary RTGel® technology to improve therapeutic profiles of existing drugs and UroGen’s sustained release technology making local delivery potentially more effective as compared to other treatment options. These statements are subject to a number of risks, uncertainties and assumptions, including, but not limited to: preliminary results may not be indicative of results that may be observed in the future; the timing and success of clinical trials and potential safety and other complications thereof; unforeseen delays that may impact the timing of progressing clinical trials and reporting data; the ability to obtain regulatory approval within the timeframe expected, or at all; there is no guarantee that the current clinical development plan for UGN-102 will ultimately support submission of an NDA, notwithstanding the current agreement with the FDA; even if an NDA for UGN-102 is accepted by the FDA, there is no guarantee that such NDA will be sufficient to support approval of UGN-102; the ability to maintain regulatory approval; complications associated with commercialization activities; the labeling for any approved product; competition in UroGen’s industry; the scope, progress and expansion of developing and commercializing UroGen’s product candidates; the size and growth of the market(s) therefor and the rate and degree of market acceptance thereof vis-à-vis alternative therapies; UroGen’s ability to attract or retain key management, members of the board of directors and personnel; UroGen’s RTGel technology may not perform as expected; UroGen may not successfully develop and receive regulatory approval of any other product that incorporates RTGel technology; UroGen’s financial condition and need for additional capital in the future.
