Study Summary

This study will evaluate the safety and efficacy of intravesical administration of 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 patients with NMIBC with Cis who are BCG-naïve or inadequately treated.

Primary Outcome

The type, incidence, relatedness and severity of treatment emergent adverse events of EG-70 as assessed by NCI-CTCAE V5.0 will be monitored.
