Athira Pharma Announces Initiation of Open Label Extension Study for LIFT-AD and ACT-AD Clinical Trials of ATH-1017 for Alzheimer’s DiseaseStudy Extension allows for additional 26 weeks of treatment on ATH-1017

BOTHELL, Wash., July 06, 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 it is enrolling patients into an open label extension (OLEX) study for its ongoing Phase 2/3 LIFT-AD and Phase 2 ACT-AD studies of ATH-1017 for the treatment of mild-to-moderate Alzheimer’s disease.

“This treatment extension allows us to meet investigator and patient interest in continuing treatment with ATH-1017. We can now collect up to 1 year of safety and efficacy data on ATH-1017, and patients who received placebo during the randomized portion of the trial will now be able to receive up to 26 weeks of therapy,” said Hans Moebius, M.D., Ph.D., Chief Medical Officer at Athira. “It’s rewarding to have our first patients completing six months of study now continue their treatment. Our novel treatment approach is agnostic to the underlying disease pathology and is designed to focus on neuronal regeneration, which has the potential to improve clinical outcomes for patients.”

“There remains an urgent need for therapies that improve cognition for patients who are living with mild-to-moderate Alzheimer’s disease,” said Michael Mega, M.D., Ph.D., Director of the Center for Cognitive Health and a principal investigator in the ACT-AD trial. “The data we will continue to collect in this open label extension could help us to better understand the long-term safety and efficacy profile of ATH-1017 and could help Athira best design future clinical trials of ATH-1017.”

The LIFT-AD and ACT-AD trials are evaluating ATH-1017, a small molecule therapeutic designed to enhance the activity of Hepatocyte Growth Factor (HGF) and its receptor, MET, which are expressed in the central nervous system, in order to promote brain health and function. The randomized, double-blind, placebo-controlled trials are evaluating the safety and efficacy of ATH-1017 in mild-to-moderate Alzheimer’s disease. Patients are stratified 1:1:1 to receive low dose ATH-1017 (40 mg/day), high dose ATH-1017 (70 mg/day) or placebo.

Patients in both trials are being evaluated for improvement in cognition, global and functional assessments comparing treatment arms to placebo. In the ACT-AD trial, quantitative electroencephalograms (qEEG) are obtained, and Event-Related-Potentials (ERP P300), a functional measure of working memory processing speed and executive function is assessed. Topline data of ACT-AD are targeted for early 2022 and topline data from LIFT-AD are targeted by the end of 2022.

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 ATH-1017 at the high dose (70 mg/day) for up to an additional 26 weeks. Investigators and patients will remain blinded to treatment group assignment in the original trials.

ATH-1017 Clinical Results
Athira’s completed Phase 1a/b clinical trials of ATH-1017 for the treatment of Alzheimer’s disease established that the treatment was generally well tolerated at all tested doses. Measures evaluating brain activity by electroencephalogram (qEEG) also produced a strong suite of translational data. Additionally, a statistically significant improvement in Event-Related Potential (ERP) P300 latency, a functional measure of working memory processing speed and executive function, was noted in patients with Alzheimer’s disease following multiple dose treatments with ATH-1017 compared with those receiving placebo. Athira is seeking to confirm a connection between P300 latency improvement and clinical cognitive benefit by ATH-1017 treatment.

ATH-1017 Patent Allowance
Athira was granted U.S. Patent No. 11,021,514 by the U.S. Patent and Trademark Office on June 1, 2021, covering the composition of matter for ATH-1017. The patent is expected to provide protection to at least June 1, 2037, not including possible patent term extension of up to 5 years provided under the Drug Price Competition and Patent Restoration Act. ATH-1017 was discovered and developed in-house at Athira Pharma based on novel data generated within the company.

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. ATH-1017’s novel mechanism of action is agnostic to the underlying disease pathology of Alzheimer’s and other dementias. It is designed to focus on network recovery and synaptic signal transmission in the brain, which has the potential to improve clinical outcomes for patients.
