for Tourette Syndrome from Asarina Pharma AB

Relmada purchases Sepranolone, a Phase 2b ready

Phase 2a results signaled improvement in Tourette

symptoms, quality of life and robust overall safety, supporting Sepranolone as a new potential first line treatment option for TS

Sepranolone (isoallopregnanolone) is a first-in-class

compound from new subgroup of neurosteroids known as GAMSAs- GABAA Modulating Steroid Antagonists - acting selectively on the

CORAL GABLES, FL, February 06, 2025 (GlobeNewswire)

-- 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.

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. We believe the Sepranolone transaction is an excellent fit with our objective to

build shareholder value by leveraging our core competencies of identifying and developing innovative compounds," 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 28% (p=0.051) - but also achieved positive results in four

key secondary endpoints compared with standard of care:

69% greater increase of Quality of Life (using

the Gilles de la Tourette Syndrome Quality of Life total score (GTS-QOL)

50% greater reduction in impairment (YGTSS)

44% greater reduction of the premonitory

urge to tic (PUTS - the Premonitory Urge to Tic scale)

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

and strategic opportunities. The Company anticipates hosting an investor update on Sepranolone's next development steps later in

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

GABA ( -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

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

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
