Investigational Therapy UGN-102 May Be Delivered at Home for the Treatment of Bladder Cancer
--In a Small Feasibility Study, UGN-102 Achieves a Complete Response in 75% (6 of 8) Patients
--UGN-102 is Being Studied in Low-Grade Intermediate-Risk Non-Muscle Invasive Bladder Cancer
“Many bladder cancer patients are elderly and suffer from comorbidities that make frequent office visits for treatment a real burden,” said study investigator
Eight patients were enrolled and treated with UGN-102 by 4 investigators. Median age was 75 years (range 55-84). Six patients completed treatment (6 doses), and 2 patients discontinued the study (5 doses and 4 doses, respectively) due to adverse events (AEs) unrelated to treatment. All 8 patients were evaluable for treatment response, and 6 of 8 (75%) achieved a complete response 3 months after starting treatment. The 2 patients who discontinued were assessed as non-responders. Treatment-related AEs were mild to moderate in severity (most common: dysuria and fatigue in 2 patients), and 3 patients with significant comorbidities had a serious AE, all of which were unrelated to treatment with UGN-102.
Patients, nurses and investigators completed home instillation feasibility questionnaires. These standardized feasibility questionnaires highlighted that all 8 patients preferred at-home to in-office treatment, and 5 of 6 patients recommended UGN-102 home instillation instead of transurethral resection of bladder tumors (TURBT). Home instillation was reported as feasible for visiting nurses, and 3 of 4 investigators considered at-home treatment “not different” than in-office treatment.
“As a urologic oncologist, I feel confident that the home instillation study results, appearing on the heels of our Phase 2 program and following the complete enrollment of our pivotal Phase 3 ENVISION study for UGN-102, provide us with even more reasons to believe that our novel approach to treating LG-IR-NMIBC has the potential to address genuine unmet needs of patients with bladder cancer,” said
The study enrolled patients with recurrent LG-IR-NMIBC who agreed to receive UGN‑102 at home. Six weekly doses of UGN-102 were administered. The first dose was administered on-site by a physician and the five remaining doses were administered at home by a visiting nurse. Patients were followed for AEs and treatment response was evaluated by visual observation, for cause biopsy, and urine cytology 3 months after treatment initiation. Complete response was defined as the absence of disease by white light cystoscopy, cytology, and histopathology.
“This study is another example of how UroGen continues to advance its mission to pioneer the way urothelial cancers are treated,” says

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.
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 therapeutic profiles of existing drugs. UroGen’s sustained release technology is designed to enable longer exposure of the urinary tract tissue to medications, making local therapy a potentially more effective treatment option. UroGen’s first commercial product, and investigational treatment UGN-102 (mitomycin) for intravesical solution for patients with LG-IR-NMIBC, are designed to ablate tumors by non-surgical means.
