The UTOPIA trial enrolled 99 patients across multiple centers globally. UGN-103 uses UroGen’s proprietary sustained release RTGel technology, a reverse-thermal hydrogel that enables sustained drug release and prolonged bladder exposure. UGN-103 is designed to offer improvements over ZUSDURI (mitomycin) for intravesical solution, including a shorter manufacturing process and simplified reconstitution procedure.

"Completing enrollment in the UTOPIA trial marks a significant milestone in our efforts to advance UGN-103 as a next-generation treatment option for patients with recurrent LG-IR-NMIBC," said Michael Louie, M.D., EVP, Medical Affairs and Clinical Development, UroGen. "UGN-103 represents a pivotal advancement in our pipeline, aiming to deliver the same non-surgical benefits to patients as ZUSDURI, while also enhancing operational efficiency and convenience for providers."

The UTOPIA trial is a single-arm, multicenter study evaluating the efficacy and safety of UGN-103. All enrolled patients receive 75 mg of UGN-103 via intravesical instillation once weekly for six weeks. The primary endpoint is complete response rate at three months, with responders entering a follow-up phase of up to 12 months to assess durability of response.

UroGen received a Notice of Allowance from the U.S. Patent and Trademark Office in September 2024 covering the use of UGN-103 for LG-IR-NMIBC, with patent protection expected through December 2041.

About UGN-103
In January 2024, UroGen entered into a licensing and supply agreement with medac to develop UGN-103 for LG-IR-NMIBC. UGN-103 is an innovative mitomycin formulation that aims to streamline manufacturing and reconstitution processes while providing intellectual property coverage until December 2041. It utilizes UroGen’s RTGel technology for prolonged mitomycin exposure.

About ZUSDURI
ZUSDURI (mitomycin) for intravesical solution is an innovative drug formulation of mitomycin, approved for the treatment of adults with recurrent LG-IR-NMIBC. Utilizing UroGen’s proprietary RTGel technology, a sustained release, hydrogel-based formulation, ZUSDURI is delivered directly into the bladder in an out-patient procedure by a trained healthcare professional using a urinary catheter to enable the treatment of tumors by non-surgical means. ZUSDURI is expected to be available in the U.S. on or around July 1, 2025. In the interim, patients can visit ZUSDURI.com for more information.

About Non-Muscle Invasive Bladder Cancer (NMIBC)
LG-IR-NMIBC affects around 82,000 people in the U.S. every year and of those, an estimated 59,000 are recurrent. Bladder cancer primarily affects older populations with increased risk of comorbidities, with the median age of diagnosis being 73 years. Guideline recommendations for the management of NMIBC include TURBT as the standard of care. Up to 70 percent of NMIBC patients experience at least one recurrence, and LG-IR-NMIBC patients are even more likely to recur and face repeated TURBT procedures.
