About Jelmyto

What is UroGen’s RTGel® technology and how does it work in Jelmyto?

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

Indications and Usage

Jelmyto® (mitomycin) for pyelocalyceal solution is indicated for the treatment of adult patients with low-grade Upper Tract Urothelial Cancer (LG-UTUC).

Important Safety Information

Contraindications

Jelmyto® (mitomycin) for pyelocalyceal solution is contraindicated in patients with perforation of the bladder or upper urinary tract.

Warnings and Precautions
Ureteric Obstruction

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.

Bone Marrow Suppression

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.

Embryo-Fetal Toxicity

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.

Adverse Reactions
Common Adverse Reactions

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.

Additional Adverse Reactions Information

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.

Use in Specific Populations
Lactation

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.

Preparation and Administration Information

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.
