- New and Recurrent Patients Treated with UGN-102 Achieved Similar Durability of Response Rates (DOR) at 12 months
PRINCETON, NJ, USA I May 04, 2024 I UroGen Pharma Ltd. (Nasdaq: URGN), a biotech company dedicated to developing and commercializing innovative solutions that treat urothelial and specialty cancers, today announced results from a new analysis of the ATLAS trial, which estimates using Kaplan Meier methods the probabilities of remaining in complete response for both new and recurrent low-grade intermediate-risk non- muscle invasive bladder cancer (LG-IR-NMIBC) patients following treatment with investigational drug UGN-102 as primary therapy, with or without subsequent transurethral resection of the bladder tumor (TURBT) at 3 months.
“These compelling findings shed light on the potential of UGN-102 as a nonsurgical primary treatment for low-grade intermediate-risk bladder cancer,” said William Huang, M.D., Urologic Oncologist, Professor and Vice Chair of Urology, NYU Grossman School of Medicine. “These data are an encouraging step forward in addressing the broad spectrum of LG-IR-NMIBC and potentially curbing the high rates of disease recurrence associated with it.”
In the Phase 3 ATLAS study, 282 patients with new or recurrent LG-IR-NMIBC were randomized to primary treatment with UGN-102 ± TURBT or TURBT alone. In the overall study population, Disease Free Survival (DFS) and DOR favored primary treatment with UGN-102 ± TURBT compared to TURBT alone. Complete response (CR) rates at the 3-month disease assessment were similar in both arms. While DFS and DOR rates were previously shared for both arms of the study, these are the first data specifically looking at the rates among new and recurrent patients within the UGN-102 ± TURBT arm. In this analysis using Kaplan Meier methods, DOR at 12 months after achieving CR at 3 months was 87.5% and 69.1% in new and recurrent patients, respectively. Also, patients achieved similar probabilities of DFS rates for UGN-102 at 15 months from randomization (77.4% and 63.2% in new and recurrent patients, respectively).
“These insightful data underscore the potential of UGN-102 impacting the treatment landscape for LG-IR-NMIBC,” said Mark Schoenberg, M.D., Chief Medical Officer, UroGen. “Our aim is for UGN-102 to emerge as a non-surgical option for LG-IR-NMIBC, potentially sparing patients from the complexities and burdens associated with repetitive surgeries, including their inherent risks, side effects, and substantial impact on both individuals and healthcare systems.”
Topline data from both the ATLAS trial and the Phase 3 ENVISION trial were initially shared in July of 2023. Twelve-month DOR data from the pivotal Phase 3 ENVISION trial are expected in June 2024.
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 completing its New Drug Application (NDA) submission for UGN-102 in September 2024 with a potential U.S. Food and Drug Administration (FDA) decision as early as the first quarter of 2025.
About Non-Muscle Invasive Bladder Cancer (NMIBC)
In the U.S. bladder cancer is the second most common urologic cancer in men. LG-IR- NMIBC represents approximately 22,000 newly diagnosed bladder cancer patients each year and an estimated 60,000 recurrences annually among patients diagnosed from previous years. Bladder cancer primarily affects older populations with the median age of diagnosis 73 years and an increased risk of comorbidities. Guideline recommendations for the management of NMIBC include TURBT as the standard of care (SOC). 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.
About ATLAS
ATLAS was 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 duration of response. 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).
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 LG-IR-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 CR 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 CR at the 3-month assessment. Based on discussions with the FDA, and assuming positive findings, UroGen anticipates submitting an NDA for UGN-102 in September 2024. Learn more about the Phase 3 ENVISION trial at www.clinicaltrials.gov (NCT05243550).
About UroGen Pharma Ltd.
UroGen is a biotech company dedicated to developing and commercializing innovative solutions that treat urothelial and specialty cancers because patients deserve better options. UroGen has developed RTGel reverse-thermal hydrogel, a proprietary sustained-release, hydrogel-based platform technology that has the potential to improve the therapeutic profiles of existing drugs.
