UroGen Pharma Initiates Rolling Submission of New Drug Application (NDA) for UGN-101 for the Treatment of Low-Grade Upper Tract Urothelial Cancer (LG UTUC)

NEW YORK--(BUSINESS WIRE)-- UroGen Pharma Ltd. (Nasdaq:URGN), a clinical-stage biopharmaceutical company developing treatments to address unmet needs in the field of urology, today announced that it has initiated the rolling submission with the U.S. Food and Drug Administration (FDA) of the New Drug Application (NDA) for UGN-101 (mitomycin gel) for instillation as a treatment for patients with low-grade upper tract urothelial cancer (LG UTUC). The company expects to complete its NDA submission by mid-2019, with potential approval in 2019.

“This is an important milestone in our mission to bring innovative, non-surgical treatment options to patients with urothelial cancers and potentially eliminate the need for repetitive surgical intervention and kidney removal,” said Ron Bentsur, Chief Executive Officer of UroGen. “UGN-101 has the potential to be the first non-surgical therapy for LG UTUC, and the first drug ever approved in this indication. We are grateful to our UroGen team and clinical investigators who have worked diligently to advance this potentially paradigm-shifting program.”

The NDA submission is supported by clinical data from the Phase 3 OLYMPUS clinical trial of UGN-101 for the non-surgical treatment of LG UTUC. Results from an interim analysis were presented at the American Urologic Association Annual Meeting in May 2018. UroGen plans to present topline data from the OLYMPUS study in January 2019.

The FDA previously granted Orphan Drug, Fast Track, and Breakthrough Therapy Designations to UGN-101 for the treatment of UTUC. If approved, UGN-101 would be the first drug approved for the non-surgical treatment of LG UTUC.
