Study Summary

This is a Phase 3, open-label, single arm trial designed to evaluate Cretostimogene patients with NMIBC who have failed prior BCG therapy. Up to approximately 115 CIS bladder cancer patients with or without HG Ta or HG T1 papillary disease will be enrolled under the original protocol through Amendment 4, which will comprise Cohort C. Cohort C is closed to enrollment. Under Amendment 5-1, Cohort P was added to enroll up to 70 patients with HG Ta/T1 papillary bladder cancer. Under Amendment 6, the target number of patients enrolled in Cohort P was increased to 75. Cohort P is open to enrollment Cohort C and Cohort P will be analyzed and reported separately. Patients will have had to fail prior BCG therapy which is defined as having persistent or recurrent disease within 12 months (Cohort C) or 6 months (Cohort P) following the completion of adequate BCG therapy for HGUC

Primary Outcome

To determine the Complete Response rate at any time in patients with BCG-unresponsive CIS with or without concomitant HG Ta/T1 papillary disease.
