On June 12, 2025 UroGen Pharma Ltd. (Nasdaq: URGN), a biotech company dedicated to developing and commercializing innovative solutions that treat urothelial and specialty cancers, reported the U.S. Food and Drug Administration (FDA) approved ZUSDURI, the first and only FDA-approved medication for adults with recurrent LG-IR-NMIBC (Press release, UroGen Pharma, JUN 12, 2025, View Source [SID1234653850]). ZUSDURI consists of mitomycin and sterile hydrogel, using UroGen’s proprietary sustained release RTGel technology. ZUSDURI has been designed for potent tumor ablation. This landmark approval is based on the positive results from the Phase 3 ENVISION trial that demonstrated ZUSDURI delivers 78% complete response (CR) for patients at 3 months, and of those patients 79% remained event-free 12 months later.

"The approval of ZUSDURI represents a significant step forward for our company and for the treatment of recurrent LG-IR-NMIBC," said Liz Barrett, President and CEO of UroGen. "For the first time, the estimated 59,000 U.S. patients facing recurrent LG-IR-NMIBC each year have access to an FDA-approved medicine. This historic achievement is a bold leap forward in our mission to redefine uro-oncology and bring innovation to patients who need it most. We are deeply grateful to the FDA for their collaboration and to the investigators, patients, and caregivers whose commitment made this milestone possible. Their contributions have been essential in bringing meaningful innovation to the bladder cancer community."

The existing standard of care for LG-IR-NMIBC is a surgical procedure typically performed under general anesthesia called transurethral resection of bladder tumor (TURBT). Due to high recurrence rates of LG-IR-NMIBC, repeat TURBTs may be necessary.

"ZUSDURI marks a breakthrough in uro-oncology, offering a new alternative for recurrent LG-IR-NMIBC patients who can live for many years with the disease but often endure multiple resections, under general anesthesia," said Dr. Sandip Prasad, MD, M.Phil., Director of Genitourinary Surgical Oncology at Morristown Medical Center/Atlantic Health System, NJ, and principal investigator of the ENVISION trial. "For decades, TURBT has been the standard approach for bladder cancer treatment. That’s why innovative treatments like ZUSDURI are essential, especially for those adult patients with recurrent low-grade, intermediate-risk NMIBC."

The most common (≥ 10%) adverse reactions, including laboratory abnormalities, that occurred in patients were increased creatinine, increased potassium, dysuria, decreased hemoglobin, increased aspartate aminotransferase, increased alanine aminotransferase, increased eosinophils, decreased lymphocytes, urinary tract infection, decreased neutrophils, and hematuria. Serious adverse reactions occurred in 12% of patients who received ZUSDURI, including, urinary retention (0.8%) and urethral stenosis (0.4%).

Product Availability

ZUSDURI is expected to be available in the U.S. on or around July 1, 2025, for the treatment of adults with recurrent LG-IR-NMIBC. In the interim, patients can visit ZUSDURI.com (available soon).

UroGen Patient Support

UroGen is committed to helping patients access ZUSDURI. UroGen Support may help identify appropriate financial assistance programs for eligible patients with commercial, Medicare or Medicaid coverage, as well as those with no insurance coverage. These programs are for eligible patients who have been prescribed ZUSDURI and who need help managing the cost of treatment. The appropriate program will depend on the patient’s insurance coverage. Visit ZUSDURI.com (available soon) or contact UroGen Support at 1-833-UROGEN-1 (1-833-876-4361) for additional information.

Post-Marketing Commitment

As a post-marketing commitment, UroGen has agreed with the FDA to complete the ongoing ENVISION trial to further characterize the clinical benefit of ZUSDURI for the treatment of patients with recurrent LG-IR-NMIBC. In addition, UroGen committed to provide the FDA annual updates on duration of response (DOR) for all patients with ongoing complete responses. The annual updates will continue until all ongoing patients experience a recurrence of LG-IR-NMIBC; progression; death; loss to follow-up; or reach 63 months after the first instillation as planned in the protocol, whichever occurs first.

About ZUSDURI

ZUSDURI (mitomycin) for intravesical solution is an innovative drug formulation of mitomycin, approved for the treatment of adults with recurrent LG-IR-NMIBC.

About Non-Muscle Invasive Bladder Cancer (NMIBC)

LG-IR-NMIBC affects around 82,000 people in the U.S. every year and of those, an estimated 59,000 are recurrent. Bladder cancer primarily affects older populations with increased risk of comorbidities, with the median age of diagnosis being 73 years. Guideline recommendations for the management of NMIBC include TURBT as the standard of care. Up to 70 percent of NMIBC patients experience at least one recurrence, and LG-IR-NMIBC patients are even more likely to recur and face repeated TURBT procedures.
