Zusduri (mitomycin) is a sustained release, hydrogel-based formulation of mitomycin for intravesical treatment of low-grade intermediate-risk non-muscle invasive bladder cancer (LG-IR-NMIBC).
- Non-muscle invasive bladder (NMIBC) cancer is cancer that is located only in the urothelium (inner layer of the bladder). Low-grade intermediate-risk NMIBC (LG-IR-NMIBC) means the cancer cells are slow growing with an intermediate-risk of spreading (risk determined by stage, grade, size, and number of tumors present).
- Zusduri contains mitomycin, an antineoplastic antibiotic first approved over forty years ago for intravenous use in the treatment of certain types of cancer, then more recently for administration directly into the bladder for the treatment of bladder cancer. UroGen's Jelmyto (mitomycin) for pyelocalyceal solution was approved in 2020 for the treatment of low-grade upper tract urothelial cancer (LG UTUC). Mitomycin is an alkylating agent that works to stop the growth of cancer cells by inhibiting the synthesis of deoxyribonucleic acid (DNA).
- Zusduri utilizes UroGen’s proprietary RTGel® technology to enable longer exposure of bladder tissue to mitomycin, thereby enabling the treatment of tumors by non-surgical means.
- FDA approval was based on positive results from the Phase 3 ENVISION trial that demonstrated that Zusduri delivered a 78% complete response for patients at 3 months, and of those patients, 79% remained event-free 12 months later.
- Zusduri is administered once a week, every six weeks using a standard urinary catheter in an outpatient setting by a trained healthcare professional.
- The most common side effects of Zusduri include increased blood creatinine levels, increased blood potassium levels, trouble with urination, decreased red blood cell counts, increase in certain blood liver tests, increased or decreased white blood cell counts, urinary tract infection, and blood in the urine.
