The Lancet Oncology Publishes Details of UroGen Pharma’s Pivotal OLYMPUS Trial
- 59% Complete Response in patients with low-grade upper tract urothelial cancer
- Kaplan-Meier analysis, based on interim data, estimated 12-month durability at 84%

U.S.FDA expedited approval of Jelmyto™ as the first non-surgical treatment for patients with this difficult-to-treat cancer
Jelmyto consists of mitomycin, an established chemotherapy, and sterile hydrogel, using UroGen’s proprietary sustained release RTGel™ technology. It has been designed to enable longer exposure of urinary tract tissue to mitomycin, thereby enabling the treatment of tumors by non-surgical means. Jelmyto is indicated for the treatment of adult patients with low-grade upper tract urothelial cancer (LG-UTUC). It is contraindicated in patients with perforation of the bladder or upper urinary tract.
“The current approach to treating low-grade upper tract urothelial cancer includes multiple endoscopic surgeries, high risk of disease recurrence and for many patients, the eventual removal of a kidney, which can present a whole new set of challenges that can adversely impact long-term health,” said
LG-UTUC is a rare cancer that develops in the lining of the upper urinary tract, ureters and kidneys. In the
In the pivotal OLYMPUS trial, participants received six once-weekly instillations of Jelmyto via retrograde catheter in the renal pelvis and calyces. The intent-to-treat (ITT) population included the seventy-one patients who received at least one dose of Jelmyto; 48% of these patients had tumors that were deemed endoscopically unresectable. As reported in The Lancet Oncology publication, Jelmyto achieved a Complete Response (CR) in 59% of the ITT population (a CR was defined as negative 3-month ureteroscopic evaluation, negative cytology and negative for cause biopsy) and durability at 12 months (at the time of the data cutoff) was estimated to be 84% by Kaplan-Meier analysis.
“The positive results of the OLYMPUS trial demonstrate that Jelmyto has the potential to help fulfill a significant unmet need for patients with low-grade upper tract urothelial cancer,” said Dr.
As reported in The Lancet Oncology publication, in the trial, 67 patients (94%) experienced adverse events (AEs) and 60 patients (85%) had AEs that were considered to be related to the study treatment or procedure. No treatment-related deaths occurred. Overall, the most frequently reported AEs were ureteric stenosis in 31 (44%) of 71 patients, urinary tract infection in 23 (32%), haematuria in 22 (31%), flank pain in 21 (30%), and nausea in 17 (24%).
About the Phase 3 OLYMPUS Trial
OLYMPUS (Optimized DeLivery of Mitomycin for Primary UTUC Study) is an open-label, single-arm Phase 3 clinical trial of UGN-101, Jelmyto (mitomycin) for pyelocalyceal solution, to evaluate the safety, tolerability and tumor ablative effect of Jelmyto in patients with low-grade UTUC. Seventy-one patients were treated at clinical sites across
Jelmyto (mitomycin) for pyelocalyceal solution, is a drug formulation of mitomycin indicated for the treatment of adult patients with low-grade upper tract urothelial cancer (LG-UTUC). Utilizing the RTGel™ technology platform, UroGen’s proprietary sustained release, hydrogel-based formulation, Jelmyto is designed to enable longer exposure of urinary tract tissue to mitomycin, thereby enabling the treatment of tumors by non-surgical means. Jelmyto is delivered to patients using standard ureteral catheters or nephrostomy tube. The

IMPORTANT SAFETY INFORMATION
You should not receive JELMYTO if you have a hole or tear (perforation) of your bladder or upper urinary tract.
Before receiving JELMYTO, tell your healthcare provider about all your medical conditions, including if you:
are pregnant or plan to become pregnant. JELMYTO can harm your unborn baby. You should not become pregnant during treatment with JELMYTO. Tell your healthcare provider right away if you become pregnant or think you may be pregnant during treatment with JELMYTO.
Females who are able to become pregnant: You should use effective birth control (contraception) during treatment with JELMYTO and for 6 months after the last dose.
Males being treated with JELMYTO: If you have a female partner who is able to become pregnant, you should use effective birth control (contraception) during treatment with JELMYTO and for 3 months after the last dose.
- are breastfeeding or plan to breastfeed. It is not known if JELMYTO passes into your breast milk. Do not breastfeed during treatment with JELMYTO and for 1 week after the last dose.
- Tell your healthcare provider if you take water pills (diuretic).
How will I receive JELMYTO?
- Your healthcare provider will tell you to take a medicine called sodium bicarbonate before each JELMYTO treatment.
- You will receive your JELMYTO dose from your healthcare provider 1 time a week for 6 weeks. It is important that you receive all 6 doses of JELMYTO according to your healthcare provider’s instructions. If you miss any appointments, call your healthcare provider as soon as possible to reschedule your appointment. Your healthcare provider may recommend up to an additional 11 monthly doses.
- JELMYTO is given to your kidney through a tube called a catheter.
- During treatment with JELMYTO, your healthcare provider may tell you to take additional medicines or change how you take your current medicines.
After receiving JELMYTO:
- JELMYTO may cause your urine color to change to a violet to blue color. Avoid contact between your skin and urine for at least 6 hours.
- To urinate, males and females should sit on a toilet and flush the toilet several times after you use it. After going to the bathroom, wash your hands, your inner thighs, and genital area well with soap and water.
- Clothing that comes in contact with urine should be washed right away and washed separately from other clothing.
JELMYTO may cause serious side effects, including:
- Swelling and narrowing of the tube that carries urine from the kidney to the bladder (ureteric obstruction). If you develop swelling and narrowing, and to protect your kidney from damage, your healthcare provider may recommend the placement of a small plastic tube (stent) in the ureter to help the kidney drain. Tell your healthcare provider right away if you develop side pain or fever during treatment with JELMYTO.
- Bone marrow problems. JELMYTO can affect your bone marrow and can cause a decrease in your white blood cell, red blood cell, and platelet counts. Your healthcare provider will do blood tests prior to each treatment to check your blood cell counts during treatment with JELMYTO. Your healthcare provider may need to temporarily or permanently stop JELMYTO if you develop bone marrow problems during treatment with JELMYTO.
The most common side effects of JELMYTO include: side pain, urinary tract infection, blood in your urine, kidney problems, tiredness, nausea, stomach pain, trouble with urination, vomiting, low red blood cell count, frequent urination, itching, chills, and fever.
