BOTHELL, Wash., March 20, 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 that study overview and baseline data from ACT-AD, a fully enrolled Phase 2 clinical trial of Athira’s lead development candidate, fosgonimeton (ATH-1017) in study participants with mild-to-moderate Alzheimer’s disease (AD), were presented in an oral presentation at the International Conference on Alzheimer’s and Parkinson’s Disease and Related Neurological Diseases (AD/PD™ 2022) taking place in Barcelona, Spain, and virtually from March 15-20, 2022.

Of the 77 study participants enrolled in the randomized, double-blind, placebo-controlled trial, the mean age is 71.4 years, with 50.6% female and 49.4% male, and an average baseline MMSE of 19.3. This includes 31 patients with mild Alzheimer’s disease (mean baseline MMSE 21.8) and 46 with moderate Alzheimer’s disease (mean baseline MMSE 17.5). The average frequency of the APOe4 gene among all study participants is in line with the general AD population. The preliminary baseline ERP P300 latency is 381 milliseconds. At a preliminary data cut, 57 patients completed the study and approximately 14 percent discontinued prior to study completion.

“The baseline data demonstrate that the patient population enrolled in the ACT-AD study are representative of the mild-to-moderate Alzheimer’s population and appropriate to evaluate the effectiveness of fosgonimeton on ERP P300 latency, a functional, objective measure of working memory processing speed,” said Hans Moebius, M.D., Ph.D., Chief Medical Officer at Athira. “Change in ERP P300 latency may be indicative of enhanced synaptic function and potentially improving Alzheimer’s disease. The topline data readout from ACT-AD, targeted for the second quarter of this year, will be informative for the future analysis of our currently enrolling, potentially pivotal Phase 3 LIFT-AD study, which has been conducted in parallel with ACT-AD.”

The data slides presented during the AD/PD™ onsite session #113 are titled, “Study Design and Participant Characteristics of a Phase 2 trial of ATH-1017, a Novel Treatment for Mild-to-Moderate Alzheimer’s Disease,” and can be found on the Events and Presentations page of the Investors section of the company’s website at www.athira.com.

About the ACT-AD Trial
ACT-AD is a randomized, double-blind, placebo-controlled, 26-week trial evaluating fosgonimeton for the treatment of mild-to-moderate AD. Eligible participants had to have a clinical diagnosis of probable AD dementia according to the NIA-AA criteria. Those enrolled, presented with mild-to-moderate AD dementia as demonstrated by a Mini-Mental State Exam (MMSE) score of 14 to 24 and a Clinical Dementia Rating (CDR) scale global score of 1 or 2. Study participants were randomized across two dose groups and the placebo group on a 1:1:1 basis to receive daily subcutaneous injection of fosgonimeton or placebo.

The primary endpoint of ACT-AD is the change in Event-Related-Potential (ERP) P300 Latency, a functional, objective measure of working memory processing speed. Secondary endpoints include measures of cognition (ADAS-COG11), the clinical global impression of change (ADCS CGIC), and the instrumental activities of daily living (ADCS-ADL23). Additionally, plasma pharmacokinetics of fosgonimeton will be assessed.

The ACT-AD trial completed enrollment in October 2021, with 77 participants. Topline data are anticipated in the second quarter of 2022. Upon completion of the ACT-AD double-blind period, eligible participants can enroll in an Open Label Extension study of fosgonimeton for up to an additional 26 weeks.

Athira’s ACT-AD trial is supported by a grant from the National Institute on Aging of the National Institutes of Health under Award Number R01AG06268.

About Fosgonimeton (ATH-1017)
Fosgonimeton (ATH-1017) is a small molecule designed to enhance the activity of hepatocyte growth factor (HGF) and its receptor, MET, to impact neurodegeneration and regenerate brain tissue. The function of the HGF/MET receptor system may be impaired in the brain under conditions of neurodegeneration. In addition to Alzheimer’s disease, fosgonimeton has the potential to address the broader dementia population, including Parkinson’s disease dementia and Dementia with Lewy bodies, as the mode of action focuses on network recovery and synaptic signal transmission in the brain.
In addition to ACT-AD, Athira is currently evaluating fosgonimeton in multiple clinical trials:

  • LIFT-AD, a Phase 3 Study in mild-to-moderate Alzheimer’s disease (NCT04488419), which is currently recruiting;

  • An Open Label Extension trial in mild-to-moderate Alzheimer’s disease (NCT04886063), which is currently enrolling; and

  • SHAPE, a Phase 2 clinical trial in participants with Parkinson’s disease dementia or Dementia with Lewy bodies (NCT04831281), which is currently recruiting.
