Relmada Therapeutics Reports 12-Month Phase 2 Interim Data for NDV-01 in Non-Muscle Invasive Bladder Cancer

• Durable 76% complete response (CR) rate at 12 months with 95% CR rate at any time in high-risk NMIBC
• BCG-unresponsive patients achieved an 80% CR rate at 12 months and 94% CR rate at any time
• Tolerability profile remains favorable – no ≥ Grade 3 treatment-related adverse events and no treatment-related discontinuations
• Data reinforces advancement of NDV-01 into Phase 3 RESCUE registrational program in second line (2L) BCG-unresponsive and adjuvant intermediate-risk NMIBC in mid-2026

CORAL GABLES, Fla., March 09, 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 12-month interim data from its ongoing Phase 2 trial evaluating NDV-01 in patients with high-risk non-muscle invasive bladder cancer (NMIBC).

The Phase 2 trial of NDV-01 demonstrated a 12-month complete response (CR) rate of 76% with a favorable safety profile. Notably, a 12-month CR rate of 80% was achieved in the BCG-unresponsive population, one of the most difficult-to-treat segments of NMIBC. Taken together, these findings support the potential best-in-class profile of NDV-01 and support advancement into the Phase 3 RESCUE registrational program evaluating NDV-01 in both 2L BCG-unresponsive and adjuvant intermediate-risk NMIBC.

“These 12-month data show the potential durability of NDV-01’s clinical response profile while continuing to demonstrate a clean safety profile,” said Raj S. Pruthi, MD, Chief Medical Officer-Oncology of Relmada Therapeutics. “Importantly, we continue to observe strong responses in patients with BCG-unresponsive disease, with no progression to muscle-invasive disease and no patients requiring radical cystectomy. We believe these interim results provide meaningful clinical validation of the program and support advancing NDV-01 into the registrational Phase 3 RESCUE program with two separate registrational pathways: 2L BCG-unresponsive and adjuvant intermediate-risk, which we expect to initiate in mid-2026.”

“I am highly encouraged by NDV-01’s high response rates, 12-month durability and favorable tolerability profile. Building on the clinical community’s familiarity with conventional Gem/Doce, these Phase 2 results provide robust validation of NDV-01’s novel sustained release formulation. In addition, NDV-01’s less than 5-minute administration simplifies dosing for clinical staff, supporting broad adoption in community urology practices where ~80% of NMIBC patients are treated – and potentially offering a significantly more streamlined user experience than currently approved therapies,” said Max Kates, MD, Director of Urologic Oncology at Johns Hopkins and Relmada Clinical Advisor.

Highlights of the 12-month follow-up data from the Ongoing Phase 2 study of NDV-01:

Efficacy in BCG-Unresponsive Subpopulation**:

• No patient had progression to muscle-invasive disease
• No patient underwent a radical cystectomy
• No patients had a ≥ Grade 3 treatment related adverse event (TRAE)
• No patients discontinued treatment due to AEs
• Of the 48 patients who received ≥ 1 dose, 30 (63%) experienced a treatment-related adverse event (AE).
• Among treatment-related AEs,
  • 54% were transient uncomfortable urination (dysuria,
