ATH-1019

– LIFT-AD and ACT-AD studies evaluating ATH-1017, a once-daily investigational drug for the treatment of mild-to-moderate Alzheimer’s disease, actively enrolling patients – – IND submissions planned for Parkinson’s disease dementia program in 1H 2021 and neuropsychiatric program by end of 2021 – – Raised $103.5M in follow-on public offering during first quarter of 2021 – BOTHELL, Wash., March 25, 2021 (GLOBE NEWSWIRE) -- Athira Pharma, Inc. (NASDAQ: ATHA), a late clinical-stage biopharmaceutical company focused on developing small molecules to restore neuronal health and stop neurodegeneration, today reported financial results for the fourth quarter and full year ended December 31, 2020 and provided recent business highlights. “2020 was a momentous year for the Athira team, particularly as we initiated two trials evaluating ATH-1017. The goal of the ACT-AD and LIFT-AD studies is to demonstrate the clinical utility of this promising agent to treat Alzheimer’s disease and preserve cognitive health. Alzheimer’s disease is an area of immense medical need and we are actively enrolling patients with the aim of reporting data in 2022,” said Leen Kawas, Ph.D., President and Chief Executive Officer at Athira. “Our novel treatment approach is agnostic to the underlying disease pathology and focuses on network recovery and information transmission in the brain, which has the potential to improve clinical outcomes for patients. Our compounds have potential in a broad range of clinical applications, and we look forward to submitting INDs for our Parkinson’s disease dementia program as well as our neuropsychiatric program this year. With our recently completed follow-on public offering, our balance sheet places us in a strong position to execute on our goals.” Recent Business Highlights and Anticipated Milestones Pipeline ATH-1017: A small molecule therapeutic specifically designed to enhance the activity of Hepatocyte Growth Factor (HGF) and its receptor, MET, which are expressed in normal central nervous system function, in order to impact neurodegeneration and regenerate brain tissue. ACT-AD trial actively enrolling patients. In November 2020, Athira initiated patient dosing in a randomized, placebo-controlled Phase 2 clinical trial evaluating ATH-1017, a once-daily investigational drug for the treatment of mild-to-moderate Alzheimer’s disease. The trial will enroll up to approximately 75 patients in the United States and Australia. Participants will be randomized across two dose groups and one placebo group on a 1:1:1 basis to receive a daily subcutaneous injection of ATH-1017 or placebo over a treatment course of 26 weeks and will be evaluated for improvement in cognition, global, and functional assessments comparing treatment arms to placebo. ACT-AD will also use electroencephalogram (EEG), to measure quantitative electroencephalogram (qEEG), and Event-Related-Potential (ERP P300), a functional measure of working memory processing speed and executive function. Results from the ACT-AD trial may provide Athira with information to help support strategic decisions around any additional trials of ATH-1017 Athira may conduct. Athira expects to report top-line data by early 2022.

Athira expects to report top-line data by early 2022. LIFT-AD actively enrolling patients. In September 2020, Athira initiated patient dosing in a randomized, double-blind, placebo-controlled Phase 2/3 clinical trial evaluating the safety, efficacy and tolerability of ATH-1017 in individuals with mild-to-moderate Alzheimer’s disease. Clinical efficacy will be measured by improvement in cognition and global/functional assessments comparing treatment arms to placebo. Up to approximately 300 patients will be randomized across two dose groups and one placebo group on a 1:1:1 basis to receive a daily subcutaneous injection of ATH-1017 or placebo over a treatment course of 26 weeks. Athira expects to report top-line data by the end of 2022.

Athira expects to submit an Investigational New Drug (IND) Application to the U.S. Food and Drug Administration (FDA) by the first half of 2021 and start a Phase 2 trial by the end of 2021. ATH-1019/1020: Novel, small molecule compounds designed to be an orally available once-daily treatment, to activate the HGF/MET system, and to distribute to the CNS as potential candidates for neuropsychiatric indications, including depression, anxiety, and potentially schizophrenia. IND filing expected by end of 2021. Athira is advancing ATH-1019 and ATH‑1020 to further development for neuropsychiatric indications and is targeting an IND submission to the FDA by the end of 2021. Late-stage non-clinical development work and potentially early clinical studies will support decisions on selection of the lead product candidate and indication moving forward.
