Relmada Therapeutics Provides Regulatory Update Confirming FDA Alignment on Registrational Studies Design for NDV-01 for Two Separate Indications
FDA written feedback supports:
- a single-arm, open-label registrational trial in 2nd-line refractory high-grade NMIBC with CIS
- a randomized vs observation single trial in intermediate-risk NMIBC in the adjuvant setting
Phase 3 program expected to initiate in 1H 2026
CORAL GABLES, Fla., Jan. 12, 2026 (GLOBE NEWSWIRE) -- Relmada Therapeutics, Inc. (Nasdaq: RLMD, “Relmada” or the “Company”), a clinical-stage biotechnology company advancing innovative therapies for oncology and central nervous system disorders, today announced that it has received written feedback from the U.S. Food and Drug Administration (FDA) regarding the registrational development pathway for NDV-01 in 2nd-line refractory, high-grade BCG-unresponsive non-muscle invasive bladder cancer (NMIBC) with carcinoma in situ (CIS) -- one of the highest-risk and most treatment-resistant NMIBC populations -- and in intermediate risk NMIBC in the adjuvant setting, where there are currently no approved therapies.
In its written response to Relmada’s Type B pre-IND submission, the FDA indicated that a single-arm, open-label clinical trial in this high-grade, BCG-unresponsive with CIS population is an appropriate registrational approach for NDV-01. This feedback provides a clear and efficient development path toward a potential NDA submission for NDV-01 as a bladder-sparing therapeutic option in a patient population with significant unmet need.
The FDA also provided separate, supportive written feedback on the Company’s planned single registrational study in intermediate-risk NMIBC in the adjuvant setting, which is expected to follow an open-label, randomized-to-observation design.
Relmada continues to anticipate initiating both registrational trials in the first half of 2026.
“We are very pleased with the FDA’s alignment on the registrational design for NDV-01 in high-grade BCG-unresponsive NMIBC,” said Raj S. Pruthi, MD, Chief Medical Officer – Oncology at Relmada Therapeutics. “A single-arm pivotal study in this setting represents a meaningful opportunity to advance an in-office, bladder-sparing therapy for patients who have few if any effective alternatives. This study represents the fastest path to approval for NDV-01.”
Dr. Pruthi continued, “We are also encouraged by the FDA’s feedback on our intermediate-risk registration plans, where we believe NDV-01 could potentially provide meaningful clinical benefit to patients where no approved treatments currently exist.”
About the Planned High-Grade Registrational Study
The planned pivotal Phase 3 study in 2nd-line, refractory, high-grade BCG-unresponsive NMIBC with carcinoma in situ (CIS) will be an open-label, single-arm trial evaluating:
- Primary endpoint: Complete response (CR) rate at any time
- Key secondary endpoint: Duration of response (DOR)
-
Assessments: Cystoscopy, cytology, and biopsy per protocol
The design reflects FDA’s written guidance on the study population, endpoint selection, and evaluation methodology and is consistent with prior FDA precedents for single-arm registrational trials in NMIBC.
About the Planned Intermediate-Risk Registrational Study
The planned pivotal Phase 3 study in intermediate-risk NMIBC in the adjuvant setting will be an open label randomized-to-observation study:
- Primary endpoint: Disease Free Survival (DFS)
- Key secondary endpoint: Duration of response (DOR)
-
Assessments: Cystoscopy, cytology, and biopsy per protocol
The design reflects FDA’s written guidance on the study population, endpoint selection, and evaluation methodology.
About NDV-01
NDV-01 is a sustained-release, intravesical formulation of gemcitabine and docetaxel (Gem/Doce), in development for the treatment of non-muscle invasive bladder cancer. It is designed to enable Gem/Doce bladder retention and gradual drug release over ten days. The formulation creates a soft matrix that enhances local exposure while minimizing systemic toxicity. The NDV-01 formulation is a ready to use, convenient to administer in-office in less than five minutes, and does not require anesthesia or specialized equipment. It is protected by patents through 2038.
About NMIBC
NMIBC represents 75-80% of all bladder cancer cases and is associated with high recurrence (50 – 80% over 5 years). With over 744,000 prevalent cases in the U.S. and limited treatment options, the market opportunity is significant. High-grade BCG-unresponsive disease represents one of the most difficult-to-treat NMIBC subtypes, with limited bladder-sparing options. Intermediate-risk NMIBC in the adjuvant setting has no currently approved therapies. NDV-01 has the potential to serve as a frontline or salvage therapy and could be applicable across multiple NMIBC subtypes.
