BOTHELL, Wash., May 13, 2021 (GLOBE NEWSWIRE) -- Athira Pharma, Inc.(NASDAQ: ATHA) (Athira), a late clinical-stage biopharmaceutical company focused on developing small molecules to restore neuronal health and stop neurodegeneration, today reported financial results for the quarter ended March 31, 2021 and provided recent business highlights.

We continue to execute on our corporate and clinical goals during this very important time in Athiras history, said Leen Kawas, Ph.D., President and Chief Executive Officer at Athira. Our clinical trials, ACT-AD and LIFT-AD, are actively enrolling and will evaluate the clinical utility of ATH-1017 to treat Alzheimers disease and improve cognitive health. In addition to developing ATH-1017 in Alzheimers disease, we plan to evaluate it in Parkinsons disease dementia. We also remain committed to advancing our expanding pipeline of novel, small molecule compounds. We have a well-defined strategic plan ahead of us and are well-funded to reach multiple clinical and regulatory milestones.

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 is actively recruiting and is anticipated to report top-line data by early 2022:Enrollment is proceeding for the randomized, placebo-controlled Phase 2 clinical trial evaluating ATH-1017, a once-daily investigational drug for the treatment of mild-to-moderate Alzheimers disease. The trial plans to enroll approximately 75 patients in the United States and Australia. Over a treatment course of 26 weeks, participants 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 will inform the clinical development strategy for any additional trials of ATH-1017. -- LIFT-AD trial is actively recruiting and is anticipated to report top-line data by the end of 2022: Enrollment is proceeding for the 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 Alzheimers disease. The trial plans to enroll approximately 300 patients. Over a treatment course of 26 weeks, participants will be randomized across two dose groups and one placebo group. Clinical efficacy will be measured by improvement in cognition and global/functional assessments comparing treatment arms to placebo. -- Phase 2 Parkinsons disease dementia trial on track to initiate at the end of 2021. Athira plans to initiate a Phase 2 trial of ATH-1017 in patients with Parkinsons disease dementia by the end of 2021.

ATH-1019/1020:Novel, small molecule compounds designed to be orally available once-daily treatments, to activate the HGF/MET system and to distribute to the central nervous system as potential candidates for neuropsychiatric indications, including depression, anxiety and potentially schizophrenia.

-- IND filing expected by end of 2021.IND-enabling studies are proceeding for ATH-1019 and ATH1020. Athira 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.

Corporate
