Frequently asked questions about UGN-501

What is UGN-501 used for?

UGN-501 is an investigational monoclonal antibody being developed for the treatment of bladder cancer, specifically recurrent non-muscle invasive bladder cancer (NMIBC), which includes urothelial carcinoma of the bladder and urothelial carcinoma in situ. It is administered intravesically, meaning directly into the bladder.

Who makes UGN-501?

UGN-501 is being developed by UroGen Pharma Ltd., a biopharmaceutical company traded on NASDAQ under the ticker symbol URGN. The company is conducting a Phase 1 clinical trial of UGN-501 in the United States.

What phase is UGN-501 in?

UGN-501 is in Phase 1 clinical development. It is an investigational drug and has not been approved by the FDA. The ongoing Phase 1 trial is a dose-escalation study designed to evaluate the safety and tolerability of UGN-501 in adult participants with recurrent NMIBC.

What clinical trials is UGN-501 in?

UGN-501 is being studied in a single Phase 1 clinical trial with the identifier NCT07725796. This is a dose-escalation study of UGN-501 administered intravesically in adult participants with recurrent non-muscle invasive bladder cancer. The trial is not yet recruiting and aims to enroll 30 participants in the United States.

How is UGN-501 administered?

UGN-501 is administered intravesically, which means it is delivered directly into the bladder through a catheter. This route of administration is used for the treatment of non-muscle invasive bladder cancer to deliver the drug locally to the tumor site.
