Relmada Therapeutics Presents Positive Initial Phase 2 NDV-01 Data at AUA2025

Core Insights - Relmada Therapeutics announced positive initial data from the Phase 2 study of NDV-01, showing that 90% of patients achieved high-grade disease-free status, indicating strong clinical activity for treating non-muscle invasive bladder cancer (NMIBC) [1][2][5] - The data was presented at the American Urology Association 2025 Annual Meeting, with a data cutoff date of April 20, 2025 [1][2] Efficacy Data - At the 3-month assessment, the overall response rate (ORR) was 85% (17 out of 20 patients), with high-grade recurrence-free survival (HGRFS) in papillary disease at 83.3% (15 out of 18 patients) [5] - Complete response (CR) in carcinoma in situ (CIS) patients was 100% (2 out of 2 patients) [5] - The treatment effect of NDV-01 was consistent across all patient groups, regardless of prior BCG exposure or disease pathology [3] Safety Profile - NDV-01 was well tolerated, with no treatment-related adverse events greater than Grade 1 [4] - The most common treatment emergent adverse events (TEAEs) were mild and transient, including urinary urgency, flank pain, and dysuria, resolving within 24-28 hours [4] Study Overview - The Phase 2 study is an open-label, single-arm, single-center study evaluating NDV-01 in patients with high-grade NMIBC, with a biweekly induction phase followed by monthly maintenance for up to one year [10] - The primary efficacy endpoints are safety and complete response rate at 12 months, while secondary endpoints include duration of response and event-free survival [7][10] Market Opportunity - The U.S. NMIBC market is estimated to be a multi-billion-dollar opportunity, driven by the increasing incidence of bladder cancer and the demand for effective, minimally invasive therapies like NDV-01 [12] - NDV-01 stands out due to its ease of administration and potential for durability of action, with expansion opportunities beyond first-line treatment [12]
