• ATH-1105 is an orally delivered, positive modulator of the neurotrophic HGF system that is currently in a Phase 1 clinical trial with completion expected by year end 2024 and commencement of dosing of ALS patients expected in 2025
  
•  Company announces cost containment measures in alignment with focus on advancing ATH-1105

BOTHELL, Wash., Sept. 17, 2024 (GLOBE NEWSWIRE) -- Athira Pharma, Inc. (NASDAQ: ATHA), a clinical stage biopharmaceutical company focused on developing small molecules to restore neuronal health and slow neurodegeneration, today announced that following the topline data readout from the Phase 2/3 LIFT-AD clinical trial of fosgonimeton to treat Alzheimer’s disease (AD) the Company plans to focus on advancing the clinical development program for ATH-1105 as a potential treatment for neurodegenerative diseases, including amyotrophic lateral sclerosis (ALS) and AD. ATH-1105 is the Company’s oral, next-generation small molecule positive modulator of the neurotrophic hepatocyte growth factor (HGF) system currently in development for the treatment of ALS.

In alignment with Athira’s focus on continued development of ATH-1105, the Company is implementing cost containment measures including a reduction in workforce of approximately 70%. Athira expects one-time costs of approximately $2.8 million and cost savings of approximately $13.4 million on an annualized basis related to the reduction in the workforce. As a result of these cost containment measures and based on its current operating plan, Athira now expects to extend its cash runway into the first quarter of 2026. Moving forward, the Company will review and consider various options including partnering and financing with the intent of extending its cash runway to achieve initial proof-of-concept and enable further development for ATH-1105 in neurodegenerative diseases.

“We are encouraged about the potential for ATH-1105, as this oral, next-generation HGF-modulating drug candidate has enhanced blood-brain-barrier penetration and improved pharmacokinetic properties. Our robust preclinical data to date have demonstrated ATH-1105's neuroprotective effects including a consistent reduction in plasma neurofilament light chain (NfL) levels,” said Mark Litton, Ph.D., President and Chief Executive Officer of Athira.

“The NfL biomarker data from the LIFT-AD study suggests that HGF modulation may reduce levels of plasma NfL with the potential effect of preventing neurodegeneration. In ALS, plasma NfL is an established marker of disease progression and neurodegeneration and reduction in NfL is associated with improvement in clinical outcomes,” said Javier San Martin, M.D., Chief Medical Officer of Athira. “We look forward to the continued development of this promising therapeutic candidate for the potential treatment of neurodegenerative diseases including ALS.”

Dr. Litton added, “I want to thank our colleagues who will be departing from Athira as part of the restructuring and acknowledge their many contributions to the development of therapeutics that modulate the neurotrophic HGF system, and to the evolution of our Company. We are sorry to see them go and wish them the very best in the future.”

The Company is conducting a first-in-human Phase 1 (NCT 06432647) double-blind, placebo-controlled trial that is enrolling up to 80 healthy volunteers to evaluate single and multiple oral ascending doses of ATH-1105. The study is evaluating the safety and tolerability of ATH-1105 and includes measurements of pharmacokinetic outcomes. Athira completed the first cohort of healthy volunteers in June 2024 and expects to complete the full study by year-end 2024, with a goal to begin dosing ALS patients in 2025.

About ATH-1105

ATH-1105 is a next-generation, orally administered, small molecule drug candidate in development for the potential treatment of ALS. In preclinical models of ALS, ATH-1105 has been shown to significantly increase survival, enhance motor and nerve function, reduce peripheral nerve demyelination and axon degeneration, and improve neurodegeneration and inflammation.
