Conditions
Summary
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.

Interventions
Patients will receive up to four cycles of EG-70 administered as a bladder instillation of a 50 mL volume of study drug via catheter with a targeted retention time of 60 minutes.One cycle lasts approximately 12 weeks and consists of either a 2-dose (Day 1 and Day 8) or 4-dose (Day 1, Day 8, Day 29 and Day 36) regimen.
Under the Treatment Period, patients will receive 4 instillations per cycle for up to 4 cycles, of EG-70 at the RP2D defined in Phase 1, administered as a bladder instillation of a 50 mL volume of study drug via catheter with a targeted retention time of 60 minutes. One cycle lasts approximately 12 weeks. For Maintenance treatment 2 doses of EG-70 will be administered as a bladder instillation per 12-week cycle.
Patients will receive via catheter a 50 mL volume of a 5-minute bladder rinse immediately prior to administration of 50 mL of detalimogene voraplasmid (EG-70) at the RP2D for 30 minutes. During the Treatment Period, patients will receive 4 instillations per cycle for up to 4 cycles of the sudy intervention. One cycle lasts approximately 12 weeks. For Maintenance treatment, 2 doses of the study intervention will be administered as a bladder instillation per 12-week cycle.
