Relmada Issues Mid-Year CEO Letter to Shareholders

CORAL GABLES, Fla., Sept. 10, 2025 (GLOBE NEWSWIRE) --Relmada Therapeutics, Inc.(Nasdaq: RLMD, “Relmada” or the “Company”), a clinical-stage biotechnology company advancing innovative therapies for oncology-related and central nervous system indications, today issued a Letter to Shareholders from Sergio Traversa, Chief Executive Officer.

Dear Fellow Shareholders:

2025 has been a truly transformational year for Relmada Therapeutics. With the year now well into its second half, I am pleased to share an update on our recent progress and to thank you for your continued support.

Earlier this year, we completed a comprehensive strategic review that reaffirmed our mission to develop life-changing treatments while building a diversified portfolio. As a result, we added two differentiated Phase 2 product candidates that significantly strengthen Relmada’s long-term value proposition:

Six-month follow-up data from our Phase 2 study of NDV-01 demonstrated impressive results, witha 91% complete response (CR) rateat any time point following treatment. These findings build on the positive three-month data presented at the2025 American Urological Association Annual Meetingand reinforce the potential of NDV-01 as a transformative, bladder-sparing therapy for NMIBC, a condition that affects approximately 600,000 patients in the U.S.

We are actively preparing to initiate aPhase 3 registrational trial in the first half of 2026, with key activities underway including regulatory filings and manufacturing scale-up.

To further support NDV-01, we added two experts in bladder cancer to the Relmada team:

Their expertise will be invaluable as we advance the program toward late-stage development.

Positive proof-of-concept data in Tourette’s syndrome suggest that sepranolone may hold promise as a therapy for compulsive disorders.In the first half of 2026,we plan to initiate aPhase 2 study in PWS, a rare genetic disorder affecting 350,000–400,000 people worldwide and characterized by compulsive behaviors such as hyperphagia (obsessive eating). Preparations, including regulatory engagement and manufacturing activities, are underway.

As we begin the autumn season, we remain optimistic about Relmada’s future. The progress of NDV-01 and sepranolone, combined with the expertise of our strengthened team, positions us well for value creation through disciplined execution and capital-efficient development.

On behalf of the entire Relmada team, thank you for your continued trust and confidence. We look forward to keeping you updated on our progress in the months ahead.

Sincerely,

Chief Executive Officer
