  • Secondary ID: N/A
  • NTC ID: NCT04690699
  • Sponsor: Istari Oncology, Inc.

BRIEF SUMMARY

This is a Phase 1/2, open-label, multi-center, single arm basket study evaluating the administration of lerapolturev ± anti programmed cell death protein 1 (PD 1)/programmed death-ligand 1 (PD L1) monoclonal antibody (mAb) (which will be referred to throughout this protocol as "anti-PD-1/L1 therapy") therapy in adult patients with solid tumor cancers. Non-muscle invasive Bladder Cancer has been selected as the tumor specific cancer of interest for enrollment.

DETAILED DESCRIPTION

Patients with recurrent non-muscle invasive bladder cancer (NMIBC) intended for transurethral resection of bladder tumor (TURBT) or cystectomy will receive lerapolturev by intravesical instillation. Approximately 12-15 patients will be enrolled.

- Received prior radiation to the pelvis.

- Received prior systemic therapy for bladder cancer, including PD-1/L1 inhibitors.

- History of vesicoureteric reflux or an indwelling urinary stent.
