Trial TC-UT-03 is a prospective, open label, single-arm trial, designed to assess the efficacy, safety, and tolerability of treatment with MitoGel™ instilled in the upper urinary system of patients with non-invasive low-grade (LG), UTUC.
Upon signing of informed consent, the patients will undergo a screening visit for eligibility evaluation. Eligible patients will be treated with MitoGel™ once weekly for a total of 6 times; in a retrograde fashion. Patients who will demonstrate CR will be treated with MitoGel™ 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 PDE Visit, during which safety and efficacy will be assessed, will take place. During this visit, the ablative effect of the MitoGel™ 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 MitoGel™ 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 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.

Drug: MitoGel™ instillations
Treatment with MitoGel™ once weekly for a total of 6 times; in a retrograde fashion. Patients who will demonstrate CR will be treated with MitoGel™ once monthly as a maintenance therapy for a total of 11 instillations or up to the first recurrence whichever comes first.

- Complete Response (CR) Rate defined as percent of patients with CR at the Primary Disease Evaluation (PDE) Visit [ Time Frame: An average of 11 weeks ]Complete Response (CR) Rate defined as percent of patients with CR at the Primary Disease Evaluation (PDE) Visit
- Adverse events rate [ Time Frame: 2 years ]Frequency (number of events) and incidence (number of patients) of adverse events
- Long Term Durability of Complete Response (CR) [ Time Frame: 12 months ]This endpoint is defined only for those patients demonstrating CR at PDE visit. The endpoint is defined dichotomously as "Success" if CR was obtained at follow-up Visit 4 (12 months post PDE visit), and "Failure" otherwise.
- CR rate at 3, 6 and 9 month after the PDE. [ Time Frame: 3, 6 and 9 month ]Durability of CR defined dichotomously as "Success" if CR was achieved at PDE visit and remained at follow-up Visit 1, Visit 2 and Visit 3 (3, 6 and 9 months post PDE visit), and "Failure" otherwise.
- Partial response (PR) to treatment [ Time Frame: An average of 11 weeks ]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.
