Athira Pharma Completes First Cohort in Phase 1 Clinical Trial of ATH-1105, an Oral, Small Molecule Drug Candidate for Amyotrophic Lateral Sclerosis (ALS)

BOTHELL, Wash., June 11, 2024 (GLOBE NEWSWIRE) -- Athira Pharma, Inc. (NASDAQ: ATHA), a late clinical-stage biopharmaceutical company focused on developing small molecules to restore neuronal health and slow neurodegeneration, today announced that it has completed the first cohort of healthy volunteers in its ongoing, first-in-human, dose escalation Phase 1 clinical study evaluating ATH-1105, an oral, small molecule positive modulator of the neurotrophic hepatocyte growth factor (HGF) system in development for the treatment of amyotrophic lateral sclerosis (ALS).

“We are particularly excited about the potential for ATH-1105 as a treatment for ALS based on our compelling preclinical data that have shown ATH-1105 can improve motor function, preserve nerve health and structure, and prolong survival in a mouse model of ALS,” said Javier San Martin, M.D., Chief Medical Officer of Athira. “We look forward to continued development of this promising therapeutic candidate for people with ALS, who are in need of therapies that improve the course of disease.”

“We are pleased to start this Phase 1 clinical trial and we are eager to explore the potential of ATH-1105 in ALS patients, which we are targeting to initiate in 2025,” said Mark Litton, Ph.D., President and Chief Executive Officer of Athira. “Our robust preclinical data to date have demonstrated ATH-1105's neuroprotective effects including a consistent reduction in plasma neurofilament light chain (NfL) levels, an established biomarker of neurodegeneration in ALS. By modulating the neurotrophic HGF system, we believe we can prevent or slow the progressive decline of motor and nerve function, reduce inflammation, preserve body weight and extend survival for patients suffering with this devastating neurodegenerative condition that has few treatment options.”

The Phase 1 (NCT 06432647) double-blind, placebo-controlled trial will enroll up to 80 healthy volunteers and evaluate single and multiple oral ascending doses. The study will evaluate the safety and tolerability of ATH-1105 and will include measurement of pharmacokinetic outcomes. Completion is expected by year-end 2024.

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.
