PRINCETON, N.J. / Jul 27, 2023 / Business Wire / UroGen Pharma Ltd. (Nasdaq: URGN), a biotech company dedicated to developing and commercializing novel solutions that treat urothelial and specialty cancers, today announced positive topline data from its Phase 3 trials ATLAS and ENVISION studying UGN-102 (mitomycin) for intravesical solution in patients with low-grade, intermediate-risk non-muscle invasive bladder cancer (LG-IR-NMIBC). Both ATLAS and ENVISION trials met their primary endpoints.
In the ATLAS trial, UGN-102 met its primary endpoint of disease-free survival, reducing risk of recurrence, progression, or death by 55%. UGN-102 also showed a 64.8% complete response rate at three months for patients who only received UGN-102, compared to a 63.6% complete response rate at three months for patients who only received a TURBT.
The ENVISION trial met its primary endpoint by demonstrating that patients treated with UGN-102 had a 79.2% rate of complete response at 3-months following the initial treatment. Additional data evaluating the secondary endpoint of duration of response from ENVISION, and the submission of a New Drug Application (NDA) (assuming additional positive findings) to the U.S. Food and Drug Administration (FDA) are anticipated in 2024.
“UGN-102 has demonstrated a robust and consistent therapeutic profile across multiple clinical trials, providing a compelling picture of its potential to be a transformational product and advance the standard of care away from repetitive surgery to a minimally invasive, non-surgical option for LG-IR-NMIBC,” says Liz Barrett, President and Chief Executive Officer of UroGen. “If approved, we anticipate UGN-102 to be a significant growth driver for UroGen as the first-ever non-surgical treatment option for a disease afflicting approximately 82,000 new patients in the U.S. each year. We are on track to deliver on our previously shared guidance for JELMYTO and now find ourselves on the precipice of a new era in bladder cancer care, and that is a very exciting place to be.”
In both trials, UGN-102, a sustained release, hydrogel-based formulation that is designed to enable longer exposure of bladder tissue to mitomycin, thereby enabling the treatment of tumors by non-surgical means, was generally well tolerated, with a side effect profile similar to that of previous clinical trials.
“While TURBT is the standard treatment for bladder cancer, the recurrent nature of LG-IR-NMIBC means that patients will undergo multiple surgeries that come with risks for this older patient population,” says Sandip Prasad, MD, M.Phil., Director of Genitourinary Surgical Oncology, Morristown Medical Center/Atlantic Health System, NJ. “Based on these compelling data, I am optimistic that UGN-102, if approved, may change the treatment paradigm for these patients who lack non-surgical options to manage the ongoing burden of this highly recurrent disease.”
The Phase 3 ATLAS clinical trial, the predecessor to ENVISION, evaluated the efficacy, durability, and safety of UGN-102 with or without TURBT vs. TURBT alone in 282 patients with LG-IR-NMIBC. ENVISION evaluated the efficacy and safety of UGN-102 as a primary chemoablative therapy in 240 patients with LG-IR-NMIBC.
UGN-102 ATLAS & ENVISION Top-line Data Review
The company is hosting a data event featuring a panel discussion with leading bladder cancer experts on Thursday, July 27, 2023 at 10:00 a.m. Eastern Time to discuss these findings and will highlight topline results from the Phase 3 ATLAS and ENVISION clinical trials.
Please register for the webinar under the Events & Presentations section of the Company’s Investor Relations site (https://investors.urogen.com/events-and-presentations).
Following the live webcast, a replay will be available on the Company's website (https://urogen.com).
About UGN-102
UGN-102 (mitomycin) for intravesical solution is an investigational drug formulation of mitomycin 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 ENVISION Phase 3 study, UroGen anticipates submitting a New Drug Application (NDA) for UGN-102 in 2024. If approved, UGN-102 would be the first non-surgical primary therapeutic to treat a subset of bladder cancer characterized by high recurrence rates and multiple surgeries.
About ENVISION
The Phase 3 ENVISION trial is a single-arm, multinational, multicenter study evaluating the efficacy and safety of UGN-102 (mitomycin) for intravesical solution as primary chemoablative therapy in patients with low-grade, intermediate-risk NMIBC. The Phase 3 ENVISION trial completed target enrollment with approximately 240 patients across 56 sites. Study participants received six once-weekly intravesical instillations of UGN-102. The primary endpoint evaluated the complete response rate at the 3-month assessment after the first instillation, and the key secondary endpoint will evaluate durability over time in patients who achieved a complete response at the three-month assessment. Based on discussions with the FDA, and assuming positive findings, UroGen anticipates submitting an NDA for UGN-102 in 2024.

About ATLAS
ATLAS is a global, open-label, randomized controlled Phase 3 trial designed to assess the efficacy and safety of UGN-102, with or without TURBT, vs. TURBT alone in patients diagnosed with LG-IR-NMIBC. The trial enrolled 282 patients in clinical sites in the U.S., Europe and Israel. Patients were randomized 1:1 to either UGN-102 or TURBT. Patients in the UGN-102 arm were treated with six weekly intravesical instillations of UGN-102. At the 3-month time point, patients were assessed for response. Patients who demonstrated a complete response to either UGN-102 or TURBT, were assessed for long-term follow-up for evidence of recurrence. Patients who demonstrated presence of persistent disease at 3-months, in either arm, underwent a TURBT and continued for long-term follow-up for evidence of recurrence. The primary endpoint of the study is disease-free survival. Learn more about the ATLAS trial at www.clinicaltrials.gov (NCT04688931)
