Data to be reviewed at Investor Event on April 28, 2025 at 4:30 PM ET
CORAL GABLES, Fla., April 28, 2025 (GLOBE NEWSWIRE) -- Relmada Therapeutics, Inc. (NASDAQ:RLMD, "Relmada", "the Company")), a clinical-stage biotechnology company, today announced that positive initial data from the Phase 2 study of NDV-01 showed that 90% of patients achieved high-grade disease-free status at any time point following treatment, demonstrating strong clinical activity and supporting further development of NDV-01 for the treatment of non-muscle invasive bladder cancer (NMIBC). The data were presented today at the American Urology Association 2025 (AUA2025) Annual Meeting with a data cutoff date of April 20, 2025. To register for the virtual Investor Event, click here.
Highlights of Phase 2 data presented at AUA2025:
Efficacy Data:
3-month Assessment:
- Overall Response Rate (ORR): 85% (17/20 patients at 3 months)
- High-Grade Recurrence-Free Survival (HGRFS) in papillary disease: 83.3% (15/18 patients)
- Complete Response (CR) in CIS patients: 100% (2/2 patients)
At any time point:
- ORR: 90% (18/20 patients)
- HGRFS in papillary disease: 88.8% (16/18 patients)
- CR in CIS patients: 100% (2/2 patients)
Disease status at 6 months:
- 100% (n=7) of evaluable patients (1 CIS, 6 Ta/T1) achieved disease free status. One of these patients was re-treated at 3 months.
"I am impressed by these promising NDV-01 data reported at AUA2025. Gemcitabine and docetaxel (GEM/DOCE) have long shown clinical utility in NMIBC, but the complexity of administration has limited their broader use," said Yair Lotan, MD, Professor of Urology and Chief of Urologic Oncology at UT Southwestern Medical Center. "A formulation like NDV-01, which is designed to increase exposure to drug and simplify delivery and accessibility, has the potential to significantly change how we manage patients with NMIBC in routine practice."
"We believe NDV-01 has the potential to become the class-leading therapy for NMIBC across a wide spectrum of patients," said Sergio Traversa, CEO of Relmada. "The data presented at AUA2025 provide compelling proof-of-concept for NDV-01 as a bladder-sparing therapy. With its strong responses and tolerability combined with an administration time of less than 10 minutes, NDV-01 represents a potentially significant advance in outpatient bladder cancer treatment. We are enthusiastic about advancing this differentiated, ready-to-use GEM/DOCE formulation to improve patient outcomes and expand treatment options in NMIBC."
Overall:
The treatment effect of NDV-01 was consistent across all patient groups, demonstrating robust activity, regardless of prior BCG exposure (BCG-naïve and BCG-unresponsive) or disease pathology (including CIS or Ta/T1 papillary).
Safety:
NDV-01 was well tolerated, with no treatment related adverse events greater than Grade 1. The most common treatment emergent adverse events (TEAEs) were urinary urgency, flank pain, and dysuria, all of which were mild and transient, resolving in 24-28 hours. No patients discontinued treatment due to adverse events.
Study Overview:
- Open-label, single-arm, single-center Phase 2 study evaluating NDV-01 in patients with HG-NMIBC (including BCG-naïve (n=8) and BCG-unresponsive (n=12))
- AUA 2025 data based on 20 enrolled patients with HG-NMIBC, including 2 patients with carcinoma in situ (CIS) and 18 patients with papillary disease (Ta/T1)
- The study continues to actively enroll patients. As of the latest cut-off, a total of 26 patients have been enrolled: 20 patients have reached the 3-month assessment. Seven patients have reached 6-month assessment
* The primary efficacy endpoints are safety and complete response rate (CRR at 12 months), and secondary efficacy endpoints are duration of response (DOR) and event free survival (EFS).
About NDV-01
NDV-01 is an innovative, investigational sustained-release formulation of two complementary chemotherapy agents, gemcitabine and docetaxel (GEM/DOCE). Designed for intravesical administration, NDV-01 forms a soft matrix within the bladder, gradually releasing drug over 10 days without requiring anesthesia or special equipment. NDV-01 is intended to simplify outpatient NMIBC treatment while maximizing local exposure, minimizing systemic toxicity, and improving patient convenience.
NDV-01 is protected by patents that extend to 2038.
About the Phase 2 Study
The Phase 2 study (NCT06663137) is an open-label, single-arm, single-center study evaluating the safety and efficacy of NDV-01 in patients with HG-NMIBC. Patients are treated with NDV-01 in a biweekly induction phase, follow by monthly maintenance for up to one year, with regular assessments via cystoscopy, cytology, and biopsy, as indicated. The primary efficacy endpoints are safety and complete response rate (CRR at 12 months), and secondary efficacy endpoints are duration of response (DOR) and event free survival (EFS).
About NMIBC
More than 90% of the approximately 83,000 new U.S. cases of urothelial cancer are estimated to be bladder cancer. For the overall bladder cancer population, 5-year survival ranges from 70 to 96% of patients, moving to 6% for patients with advanced disease. Roughly 75% of bladder cancer cases are classified as non-muscle invasive (NMIBC) and approximately 50% of cases are classified as high-grade disease, considered to have increased risk of progression and recurrence. Sources indicate that NMIBC has a 50-75% recurrence rate (over seven years) and that the U.S. prevalence of NMIBC is approximately 600,000 patients.
The U.S. NMIBC market is estimated to be a multi-billion-dollar opportunity. Global numbers are higher, in line with projections for significant growth due to the increasing incidence of bladder cancer and the demand for effective, minimally invasive potential therapies like NDV-01. Approved treatment options remain limited (mainly the immunotherapy, BCG, which has been supply constrained for some time), with high recurrence rates leading to frequent re-treatment and progression. Other emerging programs include immunotherapy combinations, single agent chemotherapy formulations and targeted therapies. NDV-01 stands out based on the large body of published data that support the efficacy of treatment with gemcitabine and docetaxel, its ease of administration and potential for durability of action. Expansion beyond first-line treatment into use as a salvage treatment or in other subgroups of NMIBC, including naïve patients, could further increase the opportunity for NDV-01.
