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.
Be ≥18 years of age (or the legal age of majority in the jurisdiction in which the study is taking place) at the time of informed consent.
Have a histologically confirmed diagnosis (within 90 days of randomization) of IR NMIBC based on the AUA/SUO criteria of IR NMIBC (excluding LGT1 tumors).
Participant must be willing to undergo all study procedures (e.g., multiple cystoscopies from Screening through the end of study and TURBT for assessment of recurrence/progression) and receive the assigned treatment, including intravesical chemotherapy if randomized into that arm.
Participant must have ≥ 1 IBCG risk factors: 1) multiple tumors, 2) early recurrence (within 1 year), 3) frequent recurrences (> 1 per year), 4) tumor size (> 3 cm), 5) failure of prior induction intravesical therapy.
Histologically confirmed stage T1 tumors.
Histologically confirmed diagnosis of HR NMIBC (including CIS) or muscle-invasive bladder cancer (MIBC), locally advanced, nonresectable, or metastatic urothelial carcinoma at any time prior to enrollment.
Has had urothelial carcinoma outside of the urinary bladder (including prostatic urethra, ureter, or renal pelvis) or has a predominant histological variant of urothelial carcinoma (UC). Ta/any T1, CIS of the upper urinary tract is allowable if treated with complete nephroureterectomy more than 24 months prior to initiating study.
Participant has tumor(s) involving the prostatic urethra (ductal or stromal).
