Phase 3 |
Detailed Description
Trial TC-UT-03 is a prospective, open label, single-arm trial, designed to assess the efficacy, safety, and tolerability of treatment with UGN-101 instilled in the upper urinary system of patients with non-invasive low-grade (LG), Upper Tract Urothelial Carcinoma (UTUC).
Upon signing of informed consent, the patients will undergo a screening visit for eligibility evaluation. Eligible patients will be treated with UGN-101 once weekly for a total of 6 times; in a retrograde fashion. Patients who will demonstrate complete response (CR) will be treated with UGN-101 once monthly as a maintenance therapy for a total of 11 instillations or up to the first recurrence whichever comes first.
Five (5) weeks (± 1 w) following the last instillation, the Primary Disease Evaluation (PDE) Visit, during which safety and efficacy will be assessed, will take place. During this visit, the ablative effect of the UGN-101 will be assessed visually, by upper tract washed urine cytology, and if there are remaining tumors, by biopsy or brush biopsy if technically feasible.
Patient demonstrating CR at PDE will undergo monthly maintenance instillations of UGN-101 up to 11 months post PDE. Safety follow-up for these patients will be done until one month post last instillation or at the end of the follow-up period in FU visit 12, which is the earlier.
For patients who did not demonstrate Complete Response, to the extent that it is possible, all remaining tumors lesions will be biopsied. The patients shall undergo any additional surgical or other treatment the Principal Investigator (PI) decides deem necessary to remove remaining tumor.
An independent Data Monitoring Committee (DMC) was assigned to this trial. Accumulating safety, tolerability and efficacy data will be monitored periodically by the DMC according to a pre-specified process and frequency detailed in the DMC charter.

Outcome Measures
Primary Outcome Measures
- The Primary Efficacy Endpoint Was the Number of Patients Attaining Complete Response (CR) at the End of the Treatment Period (PDE Visit). [An average of 11 weeks]
The primary efficacy endpoint was the number of patients attaining complete response (CR) at the end of the treatment period (Primary Disease Evaluation (PDE) visit). The CR was defined dichotomously as "Success" if CR was confirmed at PDE visit (or relevant follow-up), and "Failure" otherwise.
Secondary Outcome Measures
- The Key Secondary Efficacy Endpoint Was Long-term Durability of Complete Response (CR): Number of Patients Who Maintained CR at 12 Month Post PDE Visit. This Endpoint Was Defined Only for Those Patients Who Achieved CR at the PDE Visit. [12 months]
Continuously: Duration of CR or time-to-recurrence since the Primary Disease Evaluation (PDE) Visit (i.e., time in days from the visit at which CR was determined until recurrence or censoring). This endpoint served as the main long-term durability endpoint. Dichotomously: "Success" if CR was still present at the 12 month post-PDE Visit (at Follow-Up Visit 4), and "Failure" otherwise. This endpoint served as a supportive long-term durability endpoint.
- Durability of Complete Response (CR) for Each Follow-up Time Point. [3, 6, 9 and 12 months]
Durability of CR defined dichotomously as "Success" if CR was achieved at Primary Disease Evaluation (PDE) visit and remained at follow-up Visit 1, Visit 2 and Visit 3 (3, 6, 9 and 12 months post PDE visit), and "Failure" otherwise.
- Clinical Benefit for Patients With Partial Response (PR) at the Primary Disease Evaluation (PDE) Visit. Clinical Benefit Endpoint Was Analyzed Using the Intent-to-Treat (ITT) Analysis Set, Including Patients Who Achieved Partial Response at PDE Visit. [An average of 11 weeks]
Clinical benefit for patients with partial response (PR) at the PDE visit. Clinical benefit endpoint was analyzed using the Intent-to-Treat (ITT) Analysis Set, including patients who achieved partial response at PDE Visit.Partial response at PDE visit will be defined dichotomously, similarly to the primary efficacy endpoint. For subjects with partial response at PDE visit, originally planned and actual treatments will be compared.
- Pharmacokinetic: The PK Profiles of the First UGN-101 Instillation in the Blood Were to be Examined for the First 6 Patients. [Blood samples were collected at 0 minutes (pre-dose) and 30 minutes, 1, 2, 3, 4, 5, and 6 hours following the first instillation of UGN-101]
Cmax: maximum plasma concentration Analysis of individual plasma concentration versus time profiles showed that at 6 hours post instillation, the plasma concentrations of all 6 patients were below 2 ng/mL, with the plasma concentration of one patient dropping below the LOQ (i.e., < 0.100 ng/mL). The mean Cmax was 6.24 ng/mL (range: 2.43 to 12.80 ng/mL). The highest individual observed Cmax value of 12.80 ng/mL was 187-fold and 40 fold lower than the observed Cmax level following an intravenous bolus dose of 30 mg or 10 mg mitomycin (2.4 μg/mL and 0.52 μg/mL, respectively) and is 31 fold lower than the threshold value of 400 ng/mL for myelosuppression observed with mitomycin.

Tmax: time to maximum plasma concentration Analysis of individual plasma concentration versus time profiles showed that at 6 hours post instillation, the plasma concentrations of all 6 patients were below 2 ng/mL, with the plasma concentration of one patient dropping below the LOQ (i.e., < 0.100 ng/mL). The mean Cmax was 6.24 ng/mL (range: 2.43 to 12.80 ng/mL), and the Tmax was 1.79 hours (range: 0.50 to 5.17 hours) after instillation. The highest individual observed Cmax value of 12.80 ng/mL was 187-fold and 40 fold lower than the observed Cmax level following an intravenous bolus dose of 30 mg or 10 mg mitomycin (2.4 μg/mL and 0.52 μg/mL, respectively) and is 31 fold lower than the threshold value of 400 ng/mL for myelosuppression observed with mitomycin.
- Pharmacokinetic: The PK Profiles of the First UGN-101 Instillation in the Blood Were to be Examined for the First 6 Patients. [Blood samples were collected at 0 minutes (pre-dose) and 30 minutes, 1, 2, 3, 4, 5, and 6 hours following the first instillation with UGN-101]
Half-life (t½): terminal half-life The mean apparent t½ following instillation of mitomycin into the upper urinary tract (UUT) was 1.27 hours (76 minutes), which was longer than the true t½ of mitomycin following a 30 mg bolus injection (mean t½ value of approximately 17 minutes). The apparent t½ demonstrates that UGN-101 dissolved gradually, resulting in prolonged exposure of mitomycin following local instillation into the UUT.
Other Outcome Measures
- Safety Adverse Event Outcomes: Safety Was Monitored Throughout the Study by Reviewing Adverse Events (AEs). [Through study completion, an average of 15 months]
Treatment-emergent AEs were most frequently reported from the Renal and urinary disorders system organ class (SOC), 59 (83.1%) patients, as expected, given the underlying indication of low grade (LG) Upper tract urothelial carcinoma (UTUC) in the study population, chemotherapeutic drug in a gel matrix instilled in the upper urinary tract (UUT), and the study procedure of treatment instillation via a ureteral catheter. The toxicity within the upper urinary tract was considered consistent with the disease under study and the mode of administration of UGN-101. Most events in the Renal and urinary disorders SOC were mild to moderate in severity and resolved. No new risks were identified and the overall safety profile was consistent with the known safety profile of endoscopic administration of intravesical mitomycin and of mitomycin. Overall, based on the safety and efficacy results to date, the benefit-risk profile of UGN-101 is favorable for the treatment of LG-UTUC.
