New hope for bladder cancer: trial pits top drugs against each other
NCT ID NCT06929286
First seen Jun 27, 2026 · Last updated Aug 21, 2026 · Updated 3 times
Summary
This study compares different FDA-approved drugs for a type of bladder cancer that hasn't spread into the muscle. About 125 adults whose previous treatment with BCG didn't work will receive either a newer gene therapy or standard drugs. The goal is to see which treatment better prevents the cancer from coming back or spreading.

Inclusion Criteria: * 21 years of age or older * Being treated for high-grade NMIBC (Tis, Ta, or T1) under the care of the participating treating urologists * One or more prior induction course of BCG at any point in time and judgment by the treating urologist that BCG has failed °Any amount of maintenance BCG is allowed * In the previous 12 months, receipt of at least one instillation of any intravesical agent (induction or maintenance) or one administration of systemic therapy for NMIBC treatment * An intravesical agent can include BCG or any other NMIBC treatment * Up to 15 months from the last instillation is allowed for the treating physician to perform a transurethral resection of bladder tumor (TURBT) so long as there is evidence/suspicion of recurrent disease (by urinary cytology, imaging, or cystoscopy) within 12 months of last exposure to an intravesical agent. * In the opinion of the treating urologist, there is no contraindication to treatment with nadofaragene firadenovec (i.e. hypersensitivity to IFNa, severe immunosuppression) and there is uncertainty over whether nadofaragene is better than "best usual care" Exclusion Criteria: * Opting for treatment with radical cystectomy * Currently receiving treatment on a clinical trial of an experimental therapy for NMIBC * Prior exposure to nadofaragene firadenovec
