ATHA Athira Pharma Inc

Athira Pharma, Inc. (NASDAQ: ATHA), a clinical-stage biopharmaceutical company focused on developing small molecules to restore neuronal health and slow neurodegeneration, today reported financial results for the quarter ended September 30, 2024, and provided recent pipeline and business updates.

“We are pleased to be continuing the advancement of ATH-1105 as a potential treatment for ALS. This novel, oral, next-generation HGF-modulating drug candidate has improved blood-brain-barrier penetration and pharmacokinetic properties. Specifically, preclinically ATH-1105 has shown a consistent ability in various ALS models to reduce plasma neurofilament light chain (NfL) levels, a key marker of ALS disease progression, and to improve motor and nerve function, enhance neuronal survival, and improve biomarkers of inflammation and neurodegeneration,“ said Mark Litton, Ph.D., President and Chief Executive Officer of Athira. “We continue to progress ATH-1105 in the ongoing Phase 1 study in healthy volunteers, which is targeted to complete by year end, and look forward to dosing ALS patients in 2025.”

Clinical Development & Pipeline Programs

Athira’s drug development pipeline includes potential first-in-class and next-generation novel small molecule drug candidates designed to promote the neurotrophic hepatocyte growth factor (HGF) system, which activates neuroprotective, neurotrophic and anti-inflammatory pathways in the central nervous system. Athira’s drug candidates have distinct properties which the Company believes may be applicable to a broad range of neurodegenerative diseases.

ATH-1105 – A next-generation, novel, orally administered, small molecule drug candidate in development for the potential treatment of amyotrophic lateral sclerosis (ALS) and other neurodegenerative diseases.

• Athira 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. 
• In June 2024, Athira completed the first cohort of healthy volunteers in its ongoing, dose escalation Phase 1 trial.
• Athira expects to complete the Phase 1 study by year-end 2024 and plans to begin dosing ALS patients in 2025.
• ATH-1105’s potential is supported by a growing body of preclinical evidence demonstrating improvements in nerve and motor function, biomarkers of inflammation and neurodegeneration, and survival in various models of ALS.
• These data have been presented at a variety of key scientific and medical meetings including the American Association of Neurology (AAN), the Alzheimer’s Association International Congress (AAIC), the Northeast Amyotrophic Lateral Sclerosis Consortium® (NEALS), and the Motor Neurone Disease Association (MNDA).

Fosgonimeton (ATH-1017) – A once daily, subcutaneously administered drug candidate initially targeted for the potential treatment of Alzheimer’s disease

• In September 2024, Athira announced topline results from the LIFT-AD Phase 2/3 clinical trial of fosgonimeton in mild-to-moderate Alzheimer’s disease. The study did not meet its primary or key secondary endpoints, but biomarker and subgroup data were directionally consistent with the broad neuroprotective mechanism of action.

Plans to Explore Strategic Alternatives

• Following Athira’s receipt of the topline results of LIFT-AD, the company made the determination to explore strategic alternatives focused on maximizing stockholder value. As part of that effort, Athira has paused further development of fosgonimeton while continuing our ongoing development of ATH-1105 and are exploring partnering options. Athira has engaged Cantor Fitzgerald & Co. to act as an advisor in the process to explore strategic alternatives.

Financial Results

• Cash Position. Cash, cash equivalents and investments were $68.9 million as of September 30, 2024, compared to $147.4 million as of December 31, 2023. Net cash used in operations was $71.2 million for the nine months ended September 30, 2024, compared to $74.5 million for the nine months ended September 30, 2023.
• Research and Development (R&D) Expenses. R&D expenses were $17.9 million for the quarter ended September 30, 2024, compared to $27.2 million for the quarter ended September 30, 2023.
• General and Administrative (G&A) Expenses. G&A expenses were $7.6 million for the quarter ended September 30, 2024, compared to $7.8 million for the quarter ended September 30, 2023.
• Legal Expense. Legal expense of $4.1 million was accrued during the quarter ended September 30, 2024, in connection with the United States Department of Justice investigative demand.
• Net Loss. Net loss was $28.7 million, or $0.75 per share, for the quarter ended September 30, 2024, compared to a net loss of $33.0 million, or $0.87 per share, for the quarter ended September 30, 2023.
