Athira Pharma Reports Full Year 2021 Financial Results and Provides Clinical Update

On track to report topline data from ACT-AD Phase 2 Alzheimer’s disease study in 2Q22

Expect to complete enrollment in LIFT-AD Phase 3 Alzheimer’s disease study in 3Q22

Conference call today at 4:30 pm Eastern time

BOTHELL, Wash., March 24, 2022 (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 the company’s financial results for the year ended December 31, 2021 and provided a clinical update.

“We entered 2022 with strong momentum from the solid foundation established throughout 2021 and have made considerable progress across a number of areas key to our success,” stated Mark Litton, Ph.D., President & Chief Executive Officer of Athira Pharma. “To date, the new year has been highlighted by the publication of our Phase 1 study results with fosgonimeton and presentation of preclinical data that support our novel, innovative approach to restoring neuronal health and slowing neurodegeneration across our lead program with fosgonimeton and our first oral candidate, ATH-1020. This growing body of scientific and clinical evidence is compelling and gives us further confidence in our robust clinical development programs.”

“Importantly, we remain on track to report the topline data from our Phase 2 ACT-AD study in Alzheimer’s disease in the coming months and look forward to other value-creating milestone opportunities that we believe will bring hope to patients living with progressive neurological and neuropsychiatric diseases and enhance shareholder value for our company,” continued Dr. Litton.

Recent Highlights:

• Presented baseline Event Related Potential (ERP) P300 latency data from the ACT-AD study at the AD/PD™ conference that showed the study patient population enrolled in the Phase 2 trial are representative of the mild-to-moderate Alzheimer’s population and is appropriate to evaluate the effectiveness of fosgonimeton on ERP P300 latency, a functional, objective measure of working memory processing speed;
• Highlighted preclinical data that demonstrate the mechanism of action of the active metabolite of fosgonimeton is through positive modulation of HGF/MET and results in neurotrophic and procognitive effects in an oral presentation at the American Society for Experimental Neurotherapeutics (ASENT) Annual Meeting;
• Presented preclinical data at ASENT showing that ATH-1020, a novel orally available brain-penetrant small molecule, demonstrated neuroprotective effects, mitigated depression-like behaviors and normalized an electroencephalography (EEG) hallmark of schizophrenia in animal models;
• Published results from a Phase 1 clinical trial of fosgonimeton in healthy volunteers and subjects with Alzheimer’s disease in the peer-reviewed Journal of Alzheimer's Disease showing that fosgonimeton demonstrated a statistically significant improvement of ERP P300 latency as compared with placebo in Alzheimer’s disease patients;
• Announced fosgonimeton as World Health Organization’s recommended international nonproprietary name for lead product candidate, ATH-1017;
• Dosed the first patient in the SHAPE Phase 2 clinical trial of fosgonimeton in mild-to-moderate Parkinson’s disease dementia and Dementia with Lewy bodies; and
• Appointed life science industry leaders, Grant Pickering and Dr. Michael Panzara, to the Board of Directors.
  

Clinical Pipeline Update:

Fosgonimeton (ATH-1017) is a small molecule specifically designed to enhance the activity of Hepatocyte Growth Factor (HGF) and its receptor, MET.

ACT-AD Phase 2 Study in mild-to-moderate Alzheimer’s disease (NCT04491006)

• Enrollment in ACT-AD completed in October 2021 with 77 participants with mild-to-moderate Alzheimer’s disease across 14 sites in the United States and Australia. The primary endpoint for ACT-AD is change in ERP P300 Latency, a functional, objective measure of working memory processing speed, and includes secondary endpoints measuring cognition, function, and behavior.
• Athira remains on track to report top-line data in the second quarter of 2022.
• ACT-AD trial is supported by a grant from the National Institute on Aging of the National Institutes of Health under Award Number R01AG06268. The information presented in this press release is solely the responsibility of Athira and does not necessarily represent the official views of the National Institutes of Health.
  

LIFT-AD Phase 3 Study in mild-to-moderate Alzheimer’s Disease (NCT04488419)

• Recruitment in the LIFT-AD trial is ongoing.
• Athira increased the study sample size from 300 to approximately 420, in order to strengthen the statistical power of co-key secondary endpoints, including ADAS-Cog11.
• The company expects to complete enrollment of this potentially pivotal study in the third quarter of 2022 and to report top-line data in the first half of 2023.
  

Open Label Extension Study (NCT04886063)

• Following completion of the 26-week treatment period during the LIFT-AD or ACT-AD trials, patients may elect to continue on the open label extension and receive treatment with fosgonimeton at the high dose (70 mg/day) for up to an additional 26 weeks. Investigators and patients remain blinded to treatment group assignment in the original trials.
• The majority of eligible patients who have completed the LIFT-AD and ACT-AD studies have opted to participate in the open label extension study.

SHAPE Phase 2 Study in mild-to-moderate Parkinson’s disease dementia and Dementia with Lewy bodies (NCT04831281)

• Athira dosed the first patient in the SHAPE trial in January 2022. SHAPE is a randomized, double-blind, placebo-controlled, parallel-group Phase 2 proof-of-concept study of fosgonimeton in approximately 75 participants with mild-to-moderate Parkinson’s disease dementia or Dementia with Lewy bodies.
• The company forecasts completion of enrollment of the SHAPE study in the first half of 2023.

ATH-1020 is an orally available, brain-penetrant small molecule designed to enhance the HGF/MET system that is being advanced as a potential treatment candidate for neuropsychiatric indications.

Phase 1 Study in Healthy Volunteers (NCT05169671)

• Athira submitted an Investigational New Drug application for ATH-1020 in the fourth quarter of 2021 and received FDA clearance in January. The Phase 1 study will evaluate the safety, tolerability, and pharmacokinetics of ATH-1020 in approximately 68 healthy young and elderly volunteers.
• The company initiated the Phase 1 clinical trial for ATH-1020 in the first quarter of 2022.

• General and Administrative (G&A) Expenses. G&A expenses were $21.2 million for the year ended December 31, 2021, compared with $6.7 million for the year ended December 31, 2020, primarily due to increased personnel expense as the Company’s headcount expanded to support its continued growth. In addition, increases to G&A expenses in 2021 were the result of increases related to insurance, legal, facilities, and investor relations costs.
  
  
• Net Loss. Net loss was $54.9 million, or $1.49 per share, for the year ended December 31, 2021, compared with a net loss of $19.9 million, or $1.67 per share, for the year ended December 31, 2020.
