Frequently asked questions about UGN-501

What is UGN-501 used for?

UGN-501 is being developed for bladder cancer, specifically non-muscle invasive bladder cancer (NMIBC), including urothelial carcinoma, transitional cell carcinoma, and carcinoma in situ. It is an investigational therapy given intravesically, meaning directly into the bladder, and is being studied in adults with recurrent NMIBC.

Who is developing UGN-501?

UGN-501 is being developed by UroGen Pharma Ltd., which trades under the ticker URGN. The company is running the program as an intravesically administered monoclonal antibody for bladder cancer.

What phase is UGN-501 in?

UGN-501 is in Phase 1 clinical development. It is investigational and has not been approved by the FDA. The ongoing study is a Phase 1 dose-escalation trial, which is the earliest stage of human testing and is designed primarily to evaluate safety and dosing.

What clinical trial is UGN-501 in?

UGN-501 is being studied in one clinical trial, NCT07725796, titled a Phase 1 dose-escalation study of UGN-501 administered intravesically in adult participants with recurrent NMIBC. The trial is currently recruiting, is enrolling about 30 participants, and is taking place in the United States.

How is UGN-501 given to patients?

UGN-501 is administered intravesically, meaning it is delivered directly into the bladder rather than systemically. This route is intended to concentrate the monoclonal antibody at the site of disease in patients with non-muscle invasive bladder cancer.

Who can enroll in the UGN-501 trial?

The UGN-501 Phase 1 trial, NCT07725796, enrolls adults aged 18 years and older of any sex with recurrent non-muscle invasive bladder cancer. It does not enroll healthy volunteers, and the study is uncontrolled, meaning all participants receive UGN-501 without a comparator arm.
