UroGen Pharma Announces Enrollment of First Patient in Phase 3 Clinical Trial of MitoGel™ for Treatment of Low-Grade Upper Tract Urothelial Carcinoma

RA’ANANA, Israel and NEW YORK, April 03, 2017 (GLOBE NEWSWIRE) — UroGen Pharma Ltd., a privately held, clinical-stage biopharmaceutical company that is developing advanced non-surgical treatments to address unmet needs in the field of uro-oncology, announced today that the first patient has been enrolled in the OLYMPUS trial, an open-label, single-arm pivotal Phase 3 clinical trial of MitoGel, a novel sustained release formulation of Mitomycin C, for the treatment of non-muscle invasive, low-grade upper tract urothelial carcinoma (UTUC).

The OLYMPUS trial design is based on preliminary evidence of the safety and efficacy of MitoGel from an investigator-initiated Compassionate Use program for the treatment of severe, non-resectable, low-grade UTUC.  The OLYMPUS trial is being conducted in the United States and Europe with anticipated enrollment of approximately 70 patients.  Dr. Seth Lerner, MD FACS, Professor of Urology at Baylor College of Medicine, is the Principal Investigator of this study.

UTUC represents an unmet medical need for which there are no FDA approved drugs.  UroGen Pharma has obtained U.S. Orphan Drug Designation for MitoGel for the treatment of UTUC.

Ron Bentsur, Chief Executive Officer of UroGen Pharma, stated, “Enrollment of the first patient into our pivotal study of MitoGel for low-grade UTUC represents an important milestone for the Company.  Today, the treatment options for UTUC are a complicated endoscopic surgical procedure or surgical removal of the involved kidney and upper tract.  MitoGel, representing a potential non-surgical local treatment for low-grade UTUC patients, may become the first drug ever approved to treat for UTUC.”

Arie Belldegrun, MD, UroGen Pharma’s Chairman, commented, “We are thrilled to have taken an important step towards advancing the development of a potential treatment for low-grade UTUC that may benefit the families and individuals living with this condition.  The commencement of the MitoGel pivotal study today highlights our commitment to developing transformative therapies for people suffering from uro-oncological conditions.”

About the 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 potential approval of MitoGel in low-grade UTUC, is anticipated to enroll approximately 70 patients in clinical sites in the U.S. and Europe.  The trial will also evaluate the durability of the tumor ablative effect of MitoGel.

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.

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 and risk for progression.  Difficulties in administering and maintaining Mitomycin C or any other drug in the upper tract due to low residual duration and short exposure time of the active agent in the treated area results in low treatment efficacy and  limited use of chemoablative agents in patients with UTUC.   Furthermore, there are currently no FDA-approved drugs for the treatment of UTUC.
