A Study of NDV-01 (Sustained-release Gemcitabine-docetaxel) in Participants With Non-muscle Invasive Bladder Cancer

Summary

Study REL-NDV01-303 is a Phase 3, open-label, multi-center study to determine the safety and efficacy of NDV-01 in adult participants with NMIBC. The study will include two cohorts: * Cohort 1: a randomized, open-label, parallel group, multi-center, Phase 3 study evaluating the efficacy and safety of the NDV-01 versus observation in participants with histologically confirmed IR-NMIBC. * Cohort 2: an open-label, multi-center, single-arm Phase 3 study evaluating the efficacy and safety of the NDV-01 in two populations of high-risk NMIBC: * Cohort 2a: will include participants with HR-NMIBC who have a biopsy-proven recurrence with CIS ± papillary disease after receiving one or 2 lines of therapy for BCG-unresponsive NMIBC (approved or in development). * Cohort 2b: will include participants with high-risk papillary-only disease (without CIS) NMIBC who have a biopsy-proven recurrence with HG papillary disease after receiving one or 2 lines of therapy for BCG-unresponsive NMIBC (approved or in development). This study will evaluate the safety and efficacy of intravesical administration of NDV-01, and its effect on disease recurrence and progression in patients with NMIBC who have IR disease and have recently undergone a TURBT (Cohort 1) and in patients who have HR BCG-unresponsive disease and who have recurred after first-line therapy for BCG-unresponsive patients - both approved and in development - and are unwilling or unable to undergo radical cystectomy (Cohort 2). Both GEM and DOCE have established safety and efficacy across a range of tumor types, including IR and BCG-unresponsive NMIBC. By combining both GEM and DOCE in an intravesical extended-release formulation, Relmada believes that NDV-01 has the potential to be an agent for second-line therapy in patients who have recurred after first-line therapy in BCG-unresponsive disease, thereby avoiding radical cystectomy. This study will serve as a master protocol for all cohorts included in the study.
