About the Phase 3 OLYMPUS Trial
OLYMPUS (Optimized DeLivery of Mitomycin for Primary UTUC Study) is an open-label, single-arm Phase 3 clinical trial of MitoGel to evaluate the safety, tolerability and tumor ablative effect of MitoGel in low grade UTUC patients. The trial, designed to be a single pivotal study for the approval of MitoGel in low-grade UTUC, is anticipated to enroll approximately 70 patients at clinical sites across the U.S. and Europe. The trial will also evaluate the durability of the tumor ablative effect of MitoGel.

About UTUC
Non-muscle invasive upper tract urothelial carcinoma (UTUC) has an estimated annual incidence in the United States of up to 7,500 cases – about 5% to 10% of all new cases of urothelial cancer. There are approximately 2,500 new cases of low-grade UTUC in the U.S. with a prevalence of approximately 14,500. UTUC refers to cancer of the upper tract, which connects the bladder to the kidney, and the renal pelvis. The current standard of care for this cancer is complete or partial surgical removal of the involved kidney and upper tract. For patients with a bilateral disease, an anatomic or functionally solitary kidney, medical comorbidities or low-grade disease that present with a limited number of tumors, a kidney-conserving alternative is considered, if possible. However, due to the specific anatomy and physiology of the upper tract and renal pelvis, the performance of organ-sparing endoscopic resection and instillation of neoadjuvant or adjuvant chemotherapy are often challenging, leading to high rates of recurrence. Continuous urine flow, the inability of the upper tract to retain a liquid volume under normal circumstances and the effects of systemic peristalsis result in short exposure time of active agents in the target area. This leads to poor efficacy and limited use of standard chemoablative agents in patients with UTUC. No drugs are currently FDA-approved for the treatment of UTUC.

About MitoGel
Utilizing RTGel, UroGen’s proprietary sustained release, hydrogel-based formulation, MitoGel is designed to enable longer exposure of Mitomycin C to the urinary tract tissue, thereby potentially enabling the treatment of tumors by non-surgical means. MitoGel is administered to patients using standard intravesical catheters. The U.S. Food and Drug Administration (FDA) has granted both Orphan Drug and Fast Track designations to MitoGel for the treatment of low-grade UTUC.
