INTRODUCTION

  • Org Study ID: TC-UT-03/E
  • Secondary ID: N/A
  • NCT ID: NCT04006691
  • Sponsor: UroGen Pharma Ltd.

BRIEF SUMMARY

This trial is designed to evaluate the efficacy and safety of UGN-101 administered to the upper urinary tract (UUT) in patients who were treated in Trial TC-UT-03, found to be a complete response (CR) at the Primary Disease Evaluation (PDE) 1 Visit and are subsequently found to have a documented recurrence of low grade (LG) upper tract urothelial carcinoma (UTUC) at follow up (FU).

DETAILED DESCRIPTION

This is an open-label, single-arm, Phase 3b multicenter extension trial, designed to evaluate the efficacy and safety of UGN-101 administered to the UUT in patients who were treated in Trial TC-UT-03, found to be a CR at the PDE 1 Visit, and are subsequently found to have a documented recurrence of LG UTUC at FU.

Upon signing of informed consent, the patients will undergo their routine ureteroscopy to assess durability. A biopsy will be performed at Visit 0, if appropriate, to confirm evidence of tumor. If a high grade (HG) UTUC is confirmed by biopsy and/or cytology, the patient will be excluded from the retreatment trial. Eligible patients with confirmed LG non-invasive UTUC will be treated with 3 to 6 once-weekly instillations of UGN-101 in a retrograde fashion, per investigator's discretion.

Five weeks (± 1 week) following the last Investigational product (IP) treatment, the patient will be assessed for efficacy and safety at the PDE 2 Visit. At this visit, the patient will undergo ureteroscopy and any remaining lesions will be biopsied, and UUT urine wash will be collected for cytology.

Patients demonstrating CR at the PDE 2 Visit will undergo FU visits at 3, 6, 9, and 12 months (± 2 weeks) following the PDE 2 Visit.

The trial will be approximately 15 months, per patient: a 3- to 6-week treatment period, followed by 4 to 6 weeks post-treatment leading up to the PDE 2 Visit, and a 12-month FU post PDE 2 Visit. This trial will follow the Steering Committee, and a Data Monitoring Committee (DMC) has been assigned as established for the primary trial TC-UT-03.

PRIMARY OUTCOMES

Primary Outcome 1 - Measure: Complete response (CR) rate

Primary Outcome 1 - Timeframe: An average of 11 weeks

CONDITION

  • Carcinoma
  • Transitional Cell Carcinoma
  • Transitional Cell Cancer of the Renal Pelvis and Ureter

ELIGIBILITY

Main Inclusion Criteria:
1. Patients with recurrent LG UTUC who were found to be CR at the PDE 1 Visit (in Trial TC-UT-03).

- 2. Biopsy taken from 1 or more tumors located in the UUT shows LG urothelial carcinoma (up to 2 months before Visit 0). If there are tumors in both the kidney and the ureter, at least 1 biopsy should be taken from each location.

- 3. Urine wash cytology sampled from the UUT documenting the absence of HG urothelial cancer.

- 4. Patients must have adequate organ and bone marrow function as determined by routine laboratory tests.

- 5. Patient has no active urinary tract infection (UTI) as confirmed by urine culture or urinalysis
Main Exclusion Criteria:
1. Patient intends to be treated with systemic chemotherapy during the duration of the trial.

- 2. Patient with urinary obstruction.

- 3. Inability to deliver the IP to the UUT.

- 4. Patient has any other medical or mental condition(s) that make(s) their participation in the trial unadvisable in the opinion of the treating investigator.

- 5. Patient has a contraindication to mitomycin treatment, or known sensitivity to mitomycin.
