• Completed end of Phase 2 meeting and continued engagement with U.S. Food and Drug Administration
• Appointed Andrew Gengos as Chief Financial Officer and Chief Business Officer
• Maintains strong balance sheet to support innovative clinical development pipeline in neurodegenerative diseases through key inflection points

BOTHELL, Wash., Aug. 10, 2023 (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 reported financial results for the quarter ended June 30, 2023, and provided pipeline and business updates.

“During the second quarter, we advanced and strengthened our pipeline of small molecule therapeutic candidates, with particular focus on continued enrollment of the Phase 2/3 LIFT-AD trial of investigational fosgonimeton for the treatment of mild-to-moderate Alzheimer’s disease and advancement of our preclinical ATH-1105 program toward clinical testing, initially targeting amyotrophic lateral sclerosis,” said Mark Litton, Ph.D., President and Chief Executive Officer of Athira. “At the July Alzheimer’s Association International Conference, we presented new findings regarding both our fosgonimeton and ATH-1105 programs. These data, along with the totality of evidence generated to date, strengthen our view that our pipeline of drug candidates, which are designed to positively modulate the HGF/MET neurotrophic system, have the potential to deliver novel treatments for neurodegenerative diseases.”

“Our end of Phase 2 meeting with the U.S. Food and Drug Administration was very productive and enabled alignment with senior leadership from the Office of Neuroscience and Division of Neurology 1 on important aspects of the fosgonimeton program.   We look forward to continued communication with the FDA including discussions regarding our biomarker strategy and the LIFT-AD results, now expected in the second half of 2024,” concluded Dr. Litton.

Clinical Development & Pipeline Programs

Fosgonimeton (ATH-1017) – Small molecule designed to enhance the HGF/MET system with the potential to protect and repair neuronal networks.

End of Phase 2 Meeting (EOP2) with the U.S. Food and Drug Administration (FDA)

• In July, the Company completed an EOP2 meeting with the FDA to gain alignment on its plans for the continued clinical development of fosgonimeton as a potential treatment for mild-to-moderate Alzheimer’s disease (AD).
• The Company provided an update and discussed with FDA the ongoing LIFT-AD trial including use of the 40 mg dose, concomitant acetylcholinesterase inhibitor (AChEIs) use, biomarker analyses including neurofilament light (NfL), and the statistical analysis plan.
• The FDA noted the importance of showing effects on both cognition (ADAS-Cog11) and function (ADCS-ADL23) in this population.
• Based on FDA interactions, the Company believes that all registrational pathways remain viable and contingent on LIFT-AD results.   The FDA is open to ongoing dialogue with the Company regarding the LIFT-AD trial once completed as well as other aspects of our program to develop fosgonimeton as a potential treatment for mild-to-moderate AD.

LIFT-AD Phase 2/3 trial in mild-to-moderate Alzheimer’s disease (NCT04488419)

• In September 2022, an independent, unblinded interim efficacy and futility analysis was performed on 100 patients without concomitant AChEIs who completed the LIFT-AD Phase 2/3 trial. The positive outcome from the independent data monitoring committee supports the potential clinically meaningful activity of fosgonimeton and its potential to achieve the primary endpoint of the trial.
• LIFT-AD’s primary endpoint is the Global Statistical Test (GST), a composite of the co-key secondary endpoints ADAS-Cog11 and ADCS-ADL23. The Company expects the GST endpoint to increase the understanding of the clinical impact of fosgonimeton despite the limited trial size, while elucidating the key drivers of potential treatment effect.
• Key secondary and exploratory endpoints include changes in plasma biomarkers of neurodegeneration, protein pathology, and inflammation.
• In a protocol amendment submitted to FDA in May 2023, the LIFT-AD trial was modified to focus prospectively only on 40 mg dosing and to use this dosing group compared to placebo for the primary analysis of results.
• The Company now expects to report topline LIFT-AD results in the second half of 2024.

Open Label Extension (OLEX) trial (NCT04886063)

• In May, the Company extended the OLEX study for the Phase 2/3 LIFT-AD and Phase 2 ACT-AD trials of fosgonimeton for the treatment of mild-to-moderate AD by an additional 12 months. Eligible participants who have completed the LIFT-AD or ACT-AD trials and elect to participate in the ongoing OLEX are now able to receive up to 30 months of open-label treatment. The extension addressed investigator and patient interest in continuing treatment with fosgonimeton beyond 18 months.
• The Company believes the extension will also further enhance its long-term safety database and provide insights into fosgonimeton’s long-term effects for up to 3 years.
• The OLEX continues to enroll with greater than 85% of participants who completed either study having elected to enroll in the OLEX study.

ATH-1105 – A novel, orally available, small molecule designed to be a positive modulator of the HGF/MET system as a potential treatment candidate initially for amyotrophic lateral sclerosis (ALS).

• ATH-1105 is supported by preclinical findings that demonstrated statistically significant improvements on nerve and motor function, biomarkers of inflammation and neurodegeneration, and survival in an ALS animal model.
• IND-enabling studies will continue through the remainder of 2023 in order to support the potential initiation of first-in-human studies in the first half of 2024 to evaluate this promising drug candidate as a treatment for ALS.

Presentations and Publications

In July, the Company presented three posters at the Alzheimer’s Association International Conference 2023 (AAIC) that highlighted its pipeline of small molecule therapeutic candidates targeting HGF/MET. Data presented included:

• A post-hoc analysis of the Phase 2 ACT-AD study and data from the OLEX study in patients with mild-to-moderate AD. The data suggested that improvements in plasma biomarkers of neurodegeneration (NfL) and neuroinflammation (glial fibrillary acidic protein, or GFAP) significantly correlate with GST, a composite score of cognition and function, further supporting the potential clinical utility of these biomarkers.
• Preclinical data demonstrating that fosgonimeton attenuates amyloid-β-mediated toxicity in vitro and highlighting its potential as a therapeutic candidate to slow disease progression and restore neuronal health.
• Preclinical data demonstrating that ATH-1105 offers protection against several pathologies common to ALS and frontotemporal dementia and supporting its therapeutic potential for the treatment of these indications.

Corporate Updates

The Company appointed seasoned finance and corporate strategy executive Andrew Gengos as Chief Financial Officer and Chief Business Officer.

• Most recently, Mr. Gengos served as the Chief Business Officer at Cyteir Therapeutics and has held executive roles at ImmunoCellular Therapeutics, Neuraltus Pharmaceuticals, AOBiome Therapeutics, and Synlogic.
