RTGel® is UroGen’s proprietary reverse-thermal hydrogel technology, designed to enable sustained exposure of medicine to the upper urinary tract and expand therapeutic options for upper urinary tract cancers. Jelmyto combines mitomycin with RTGel technology, allowing it to be instilled as a chilled liquid that transforms into a semisolid gel at body temperature.1
In the upper urinary tract, Jelmyto fills and conforms to the renal pelvis, providing 4 to 6 hours of mitomycin exposure before being excreted through normal urine flow.1
Jelmyto may be administered in a variety of sites of care, including hospital outpatient departments (HOPDs), ambulatory surgical centers (ASCs), and clinics.2 UroGen offers resources to help practices establish and operationalize Jelmyto at an appropriate site of care, including operational workflow, reimbursement, and coding and payment education and resources.
The UroGen team can help your practice get set up and ready to order Jelmyto. New customers should complete the Account Setup Form to establish or verify an account with Cardinal Health SPD or Cencora-Besse Specialty Distributor and authorize UroGen Support™ to place product orders on their behalf. You can then register to get UroGen Support Portal access so you can manage your account.
Account setup can take up to 30 days, so practices are encouraged to begin the process early.
Yes. Jelmyto has 100% payer coverage across Medicare Fee-for-Service, Managed Medicare, and commercial insurance.*
Coverage does not guarantee reimbursement. Providers are encouraged to perform a full benefits investigation prior to treatment to confirm individual patient coverage.
Jelmyto® (mitomycin) for pyelocalyceal solution is indicated for the treatment of adult patients with low-grade Upper Tract Urothelial Cancer (LG-UTUC).
Jelmyto® (mitomycin) for pyelocalyceal solution is contraindicated in patients with perforation of the bladder or upper urinary tract.
Ureteric obstruction, including ureteral stenosis and hydronephrosis, occurred in patients receiving Jelmyto. Monitor patients for signs and symptoms of ureteric obstruction, including flank pain, and fever, and for changes in renal function. Patients who experience obstruction may require transient or long-term ureteral stents or alternative procedures. Withhold or permanently discontinue JELMYTO based on the severity of ureteric obstruction.
The use of Jelmyto can result in bone marrow suppression, particularly thrombocytopenia and neutropenia. The following tests should be obtained prior to each treatment: Platelet count, white blood cell count differential and hemoglobin. Withhold JELMYTO for Grade 2 thrombocytopenia or neutropenia. Permanently discontinue for Grade 3 or greater thrombocytopenia or neutropenia.
Based on findings in animals and mechanism of action, Jelmyto can cause fetal harm when administered to a pregnant woman. In animal reproduction studies, administration of mitomycin resulted in teratogenicity. Advise females of reproductive potential to use effective contraception during treatment with JELMYTO and for 6 months following the last dose. Advise male patients with female partners of reproductive potential to use effective contraception during treatment with JELMYTO and for 3 months following the last dose.
The most common adverse reactions in ≥ 20% of patients treated with Jelmyto were ureteric obstruction, flank pain, urinary tract infection, hematuria, renal dysfunction, nausea, abdominal pain, fatigue, dysuria, and vomiting.
Selected clinically relevant adverse reactions in < 10% and ≥ 2% of patients who received Jelmyto include urinary tract inflammation, bladder spasm, urosepsis, hypersensitivity, and instillation site pain.
Because of the potential for serious adverse reactions in a breastfed child, advise women not to breastfeed during treatment with Jelmyto and for 1 week following the last dose.
Jelmyto is for pyelocalyceal use only and not for intravenous use, topical use, or oral administration. Jelmyto must be prepared and administered by a healthcare provider. To ensure proper dosing, it is important to follow the preparation instructions found in the JELMYTO Instructions for Pharmacy and administration instructions found in the JELMYTO Instructions for Administration.
Jelmyto may discolor urine to a violet to blue color following the instillation procedure. Advise patients to avoid contact with urine for at least six hours post-instillation, to void urine sitting on a toilet, and to flush the toilet several times after use.
Jelmyto is a hazardous drug. Follow applicable special handling and disposal procedures.
