About this trial

This study will evaluate the safety and efficacy of intravesical administration of detalimogene (EG-70) in the bladder and its effect on bladder tumors in patients with NMIBC.

This study study consists of two phases; a Phase 1 dose-escalation to establish safety and recommended the phase 2 dose, followed by a Phase 2 study to establish how effective the treatment is. The Study will include patients with: NMIBC with CIS for whom BCG therapy is unresponsive, and other high risk patients with NMIBC.

A Substudy will include a surfactant bladder rinse prior to the instillation of detalimogene in patients with NMIBC with CIS for whom BCG therapy is unresponsive.
