Intravesical Administration of rAd-IFN/Syn3 in Patients With BCG-Refractory or Relapsed Bladder Cancer
A Phase 2, Randomized, Open Label, Parallel Arm Study to Evaluate the Safety and Efficacy of rAd-IFN/Syn3 Following Intravesical Administration in Subjects With High Grade, BCG Refractory or Relapsed Superficial Bladder Cancer
Study Overview
Detailed Description
Criteria for Evaluation:
Efficacy: A Response is defined as no evidence of recurrence of a high grade tumor by cystoscopy, cytology or if clinically indicated, biopsy.
Safety: The safety and tolerability of INSTILADRIN will be evaluated based on adverse event reports, vital signs, ECGs, clinical laboratory values and results of physical examination.

Primary Outcome Measures

Measure Description |
Time Frame |
---|---|---|
Incidence of High Grade-Recurrence Free Survival at 360 Days
Time Frame: 360 Days
|
Following the initial treatment, patients were clinically evaluated and re-treated at the Days 90, 180, and 270 time points, as outlined below.
The decision to repeat treatment was determined by the clinical response observed following the previous treatment(s).
Patients were assessed for High-Grade disease recurrence by cytology, cystoscopy and, if clinically indicated, biopsies were performed to obtain accurate staging.
If no evidence of recurrence of High-Grade disease was detected, then a further dose of rAd-IFN/Syn3 was administered as maintenance therapy.
Patients who had recurrence of High-Grade disease were withdrawn from treatment but were followed for survival and time to cystectomy.
At 360 Days, a final efficacy evaluation was performed for patients receiving 4 doses of drug.
This included cystoscopy, cytology, and biopsy.
