Insights
This strategic acquisition marks a significant pivot for Relmada, introducing a Phase 2b-ready asset with compelling clinical data in the underserved Tourette syndrome market. The Phase 2a results are particularly noteworthy, showing a
The market opportunity is substantial - current TS treatments like antipsychotics and alpha-2 agonists have significant limitations due to side effects and modest efficacy. Sepranolone's clean safety profile and selective mechanism of action as a GAMSA could position it as a potential first-line treatment, addressing a important market gap.
Key investment considerations include:
- The compound's unique mechanism targeting the GABAA pathway represents a novel approach in TS treatment
- The robust safety profile with no CNS off-target effects significantly de-risks the development pathway
- The twice-weekly subcutaneous administration could present both opportunities (consistent drug levels) and challenges (patient compliance)
- The p-value of 0.051 for the primary endpoint, while just missing statistical significance, shows strong clinical relevance given the magnitude of effect
For Relmada's portfolio strategy, this acquisition represents a calculated diversification move, potentially reducing the company's risk profile by adding a mid-stage asset with demonstrated clinical signals. The timing aligns with management's stated objective of exploring strategic assets, suggesting disciplined execution of their growth strategy.
The clinical data for Sepranolone presents a compelling efficacy and safety profile that could potentially reshape the TS treatment landscape. The Yale Global Tic Severity Scale (YGTSS) reduction of
Several aspects of the Phase 2a results warrant particular attention:
- The
69% improvement in quality of life (GTS-QOL) suggests benefits beyond mere tic reduction - The
50% reduction in impairment and44% decrease in premonitory urge to tic indicate comprehensive symptom control - The absence of CNS off-target effects is crucial, as current treatments often cause sedation, weight gain, or cognitive issues
The selective GABAA pathway modulation represents a novel therapeutic approach, potentially offering more precise intervention in the neurological circuits involved in TS. While the Phase 2a study's sample size (n=26) is modest, the consistency across multiple endpoints and the clean safety profile provide a strong foundation for the upcoming Phase 2b program.
The twice-weekly subcutaneous administration, while requiring patient compliance, could offer advantages in maintaining steady drug levels compared to oral medications. This could be particularly beneficial in managing the fluctuating nature of TS symptoms.

Sepranolone (isoallopregnanolone) is a first-in-class compound from new subgroup of neurosteroids known as GAMSAs- GABAA Modulating Steroid Antagonists - acting selectively on the GABAA pathway, potentially alleviating the negative effect of Allopregnanolone in Tourette syndrome and other compulsive disorders
CORAL GABLES, Fla., Feb. 06, 2025 (GLOBE NEWSWIRE) -- Relmada Therapeutics, Inc. (Nasdaq: RLMD, “Relmada”, “the Company”), a clinical-stage biotechnology company, today announced the acquisition of Sepranolone, a Phase 2b ready neurosteroid, from Asarina Pharma AB (Asarina), being developed for the potential treatment of Tourette syndrome (TS) and other compulsive disorders.
“We are very pleased to announce this agreement with Asarina. Sepranolone aligns with our Company’s mission to find solutions for difficult-to-treat central nervous system (CNS) disorders. There is a serious unmet need for improved TS therapies not only reducing tics but also improving quality of life without serious side effects. We have been impressed by the encouraging Phase 2a efficacy signal with clinically meaningful tic reductions and quality-of-life improvements, combined with a robust safety data package showing no CNS off-target effects, that we believe reflect the compound’s selective binding properties,” said Sergio Traversa, Chief Executive Officer of Relmada. “We believe that this transaction is an excellent fit with our objective to build shareholder value by leveraging our core competencies of identifying and developing innovative compounds.”
Luca Pani, MD, Professor of Clinical Psychiatry at the University of Miami Miller School of Medicine, commented, "While current treatments for Tourette syndrome provide only modest tic reduction and are often accompanied by significant side effects, the Phase 2a data suggest that Sepranolone has the potential to offer meaningful symptom relief with a more favorable safety profile. These findings are promising, and I look forward to seeing further clinical development of this novel therapy.”
“Late last year we announced that Relmada would explore strategic assets and strategic options,” commented Maged Shenouda, Chief Financial Officer of Relmada. “Based on our extensive due diligence, including a carefully conducted review of the clinical and regulatory data, and consultation with well-respected outside experts, we believe the promising Phase 2a data suggest that Sepranolone has the potential to become first line treatment for TS.”
Clinical Data on Sepranolone
Sepranolone (isoallopregnanolone) is a first-in-class GABAA Modulating Steroid Antagonist (GAMSA), which selectively targets the GABAA (GABAA) pathway to counteract the effects of Allopregnanolone, a neurosteroid implicated in TS and other compulsive disorders.
Data from an open-label Phase 2a randomized study demonstrated that Sepranolone has the potential to improve TS symptoms versus standard of care alone, as measured by changes in the YGTSS scoring system (the world-standard Yale Global Tic Severity Scale) compared to baseline. In the 12-week, dual-center, parallel-group study, 26 subjects were treated with Sepranolone (10 mg, administered by subcutaneous injection twice weekly in addition to standard of care (SOC) versus standard of care alone.
The Phase 2a results showed competitive tic reduction and improved quality of life while displaying no CNS off-target effects. Sepranolone not only reduced tic severity in its primary clinical endpoint as measured by YGTSS by
no off-target CNS effects or systemic side effects – a crucial metric for CNS drugs in an indication where legacy and new treatments in developments involve sometimes severe side effects
Strategic Outlook
Relmada continues to evaluate additional product and strategic opportunities. The Company anticipates hosting an investor update on Sepranolone’s next development steps later in 2025.
About the Asarina Agreement
Under the terms of the agreement, Relmada acquired full global ownership rights to Sepranolone from Asarina Pharma AB, a Swedish biopharmaceutical company through an asset purchase agreement for EUR 3 Million.
About Neurotransmitter Modulators and Sepranolone
Sepranolone is a pioneering GAMSA that selectively inhibits the effects of Allopregnanolone, a neurosteroid linked to compulsive disorders such as TS and obsessive-compulsive disorder (OCD). Evaluated in multiple clinical neuro/hormonal studies involving over 335 participants, Sepranolone has demonstrated a favorable safety profile.
GABA (γ-aminobutyric acid) is the brain’s primary inhibitory neurotransmitter, helping to regulate anxiety and compulsive disorders. While Allopregnanolone typically enhances GABA’s calming effects, in some individuals it paradoxically exacerbates anxiety and compulsive. Sepranolone normalizes GABAA receptor activity by targeting two specific receptor subtypes (alpha-2 and alpha-4) without directly interfering with GABA signaling, making it a novel and selective treatment approach for TS and related disorders.
Sepranolone is protected by multiple issued patents until 2038.
About Tourette syndrome (TS)
Tourette syndrome is a complex neurological condition characterized by involuntary tics. The Centers for Disease Control and Prevention (CDC) estimates that more than 350,000 children in the U.S. have TS, with onset typically occurring between ages five and ten. Though symptoms often improve in adulthood, many individuals experience chronic tics and associated psychosocial challenges. Existing treatments include dopamine D2 blockers, atypical antipsychotics, botulinum toxin injections, cognitive behavioral therapy (CBIT), and deep brain stimulation, but these options are often limited by significant side effects.
TS is believed to be influenced by genetic, environmental, and neurochemical factors, including the role of Allopregnanolone in triggering compulsive behaviors. Current treatments target dopamine and other neurotransmitters, but the Company believes Sepranolone’s modulation of Allopregnanolone offers a novel and potentially safer alternative.
