Dr. Quirk brings more than 20 years of neuroscience drug discovery and development experience to lead Relmada's sepranolone program, building on his tenure as Chief Scientific Officer at Sage Therapeutics.

CORAL GABLES, Fla., June 11, 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 the appointment of Michael Quirk, PhD, as Senior Advisor – Sepranolone Program. Dr. Quirk's deep expertise in CNS translational science, neuroactive steroid biology, and clinical development will be instrumental in advancing sepranolone, Relmada's GABA_A receptor modulator program targeting Prader-Willi Syndrome and other CNS indications.

"We are very pleased to welcome Mike to the Relmada team. His distinguished career in CNS drug discovery and development, including his leadership of research and scientific strategy at Sage Therapeutics, gives him a unique and highly relevant perspective on neuroactive steroid biology that we believe will be invaluable to the sepranolone program," said Sergio Traversa, Chief Executive Officer of Relmada Therapeutics.

"Sepranolone's mechanism of action – selectively antagonizing the effects of allopregnanolone at GABA-A receptors without broadly disrupting GABAergic signaling – represents a precise and elegant approach to modulating neural circuits that are dysregulated in compulsivity-related disorders like Prader-Willi syndrome," said Dr. Quirk, Senior Advisor – Sepranolone Program. "I believe sepranolone has the potential to be a genuinely differentiated medicine for patients who currently have very limited options. I am excited to join the Relmada team and contribute to advancing this program toward clinical proof-of-concept."

Prior to joining Sage in 2014, Mike was a Director within the Neuroscience Innovative Medicine group at AstraZeneca working on a variety of programs within psychiatry and neurology.

Mike holds both an S.B. degree in Cognitive Science and a Ph.D. in Systems Neuroscience from the Massachusetts Institute of Technology and completed his post-doctoral training at Cold Spring Harbor Laboratory in New York studying neural mechanisms of decision-making and goal-directed behavior.

About Sepranolone and GABA Modulation

Sepranolone, a synthetic isoallopregnanolone, selectively modulates GABA_A receptors by antagonizing allopregnanolone (ALLO), without disrupting GABA signaling. It targets disorders linked to excess GABAergic activity such as Prader-Willi syndrome, Tourette syndrome, and obsessive-compulsive disorder (OCD). More than 335 patients have been treated with sepranolone in clinical trials to date, with an excellent safety profile.

About Prader-Willi Syndrome (PWS)

PWS is a rare genetic disorder caused by chromosomal deletions on chromosome 15, leading to neurodevelopmental and behavioral complications. Global prevalence is estimated to be 350,000-400,000 patients. Current treatments address symptoms but do not modify the underlying neurobehavioral pathology.

About Relmada Therapeutics, Inc.

Relmada Therapeutics is a clinical-stage biotechnology company focused on developing transformative therapies for oncology and central nervous system conditions. Its lead candidates, NDV-01 and sepranolone, are advancing through mid-stage clinical development with the potential to address significant unmet needs.
