Athira Pharma Presents Overview and Update from ACT-AD and LIFT-AD Trials of ATH-1017 in mild-to-moderate Alzheimer’s Disease at CTAD Conference

– Balanced baseline characteristics in ACT-AD and LIFT-AD to date –
– Topline data from ACT-AD trial targeted for first half of 2022 –

BOTHELL, Wash., Nov. 10, 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 announced that Hans Moebius, M.D., Ph.D., Chief Medical Officer at Athira, presented an overview and updates from two ongoing late-stage clinical trials (ACT-AD and LIFT-AD) with Athira’s lead development candidate ATH-1017 in mild-to-moderate Alzheimer’s disease, in an oral presentation at the 2021 Clinical Trials on Alzheimer’s Disease (CTAD) conference in Boston.

ACT-AD and LIFT-AD are both randomized, double-blind, placebo-controlled, parallel-group 26-week trials evaluating ATH-1017 for the treatment of mild-to-moderate Alzheimer’s disease. ATH-1017 is designed to enhance synaptic activity.

"Thus far, baseline characteristics are consistent between ACT-AD and LIFT-AD trials and the average disease severity from both trials is in keeping with the initial Phase 1b AD cohort which showed a statistically significant benefit in Event-Related-Potential (ERP) P300 latency, a functional measure of working memory processing speed. We are encouraged by the safety profile to-date and low early termination rates from both studies as well as the rate of enrollment,” said Dr. Moebius. “We expect data read out from the ACT-AD trial, with a primary endpoint of ERP P300 Latency and secondary endpoints measuring cognition, function, and behavior, in the first half of 2022. These results will provide important insights into ATH-1017’s treatment effects in Alzheimer’s disease.”

Study participants in ACT-AD and LIFT-AD are stratified 1:1:1 to receive low dose ATH-1017 (40 mg/day), high dose ATH-1017 (70 mg/day), or placebo. Upon completion of either the ACT-AD or LIFT-AD treatment protocol, those interested may enroll in Athira’s Open Label Extension study of ATH-1017. The ACT-AD trial has completed enrollment with topline data expected in the first half of 2022. “We are extremely grateful to the community of patients and researchers participating in this program and sincerely appreciate all that they have done to get us to this point,” said Mark Litton, Ph.D., President and Chief Executive Officer at Athira. “Regardless of the root cause of Alzheimer’s disease, a therapy that has potential to target the cognitive symptoms caused by neurodegeneration is needed to address the unmet patient need, and ATH-1017 has the potential to meet that need.”

About ATH-1017
ATH-1017 is 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 but depleted in Alzheimer’s disease, in order to fight neurodegeneration and regenerate brain tissue. In addition to Alzheimer’s disease, ATH-1017 is designed to address the broader dementia population, including Parkinson’s disease dementia and dementia with Lewy bodies. ATH-1017 is designed to focus on network recovery and synaptic signal transmission in the brain, which has the potential to improve clinical outcomes for patients.

About ACT-AD
ACT-AD is a randomized, double-blind, placebo-controlled, parallel-group Phase 2 trial for ATH-1017 in subjects with mild-to-moderate Alzheimer’s disease. The study has completed enrollment with 77 subjects in the United States and Australia. Study participants were randomized across two dose groups and one placebo group on a 1:1:1 basis to receive a subcutaneous injection of ATH-1017 or placebo once daily over a treatment course of 26 weeks. The primary endpoint for ACT-AD is Event-Related-Potential (ERP) P300 Latency, a functional measure of working memory processing speed, and secondary endpoints measuring cognition, function, and behavior. Additional information on the study can be found at: https://clinicaltrials.gov/ct2/show/NCT04491006. The 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 and at the CTAD conference is solely the responsibility of Athira and does not necessarily represent the official views of the National Institutes of Health.

About LIFT-AD
LIFT-AD is a randomized, double-blind, placebo-controlled, parallel-group Phase 2/3 trial for ATH-1017 for subjects with mild-to-moderate Alzheimer’s disease. The study will enroll approximately 300 subjects in the United States, with enrollment ongoing. Subjects are randomized across two dose groups and one placebo group on a 1:1:1 basis to receive a subcutaneous injection of ATH-1017 or placebo once daily over a treatment course of 26 weeks. The primary endpoint for LIFT-AD will be measured by the Global Statistical Test, which is a mathematical algorithm that combines the scores from cognition (Alzheimer's Disease Assessment Scale-Cognitive Subscale [ADAS-Cog11]), and either global impression of change (Alzheimer's Disease Cooperative Study-Clinical Global Impression of Change [ADCS-CGIC]), or function (Alzheimer’s Disease Cooperative Study-Activities of Daily Living [ADCS-ADL23]).
