April 3, 2025 updated by: Athira Pharma

A Randomized, Placebo-Controlled, Double-Blind Study of ATH-1017 Treatment in Subjects With Mild to Moderate Alzheimer's Disease

This study is designed to evaluate safety and efficacy of fosgonimeton (ATH-1017) in the treatment of mild to moderate Alzheimer's disease with a randomized treatment duration of 26-weeks.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

The study is designed to evaluate safety and efficacy of ATH-1017 in mild to moderate AD subjects, with randomized, parallel-arm treatment duration of 26 weeks, and based on clinical diagnostic criteria of Alzheimer's disease. Clinical efficacy is demonstrated by improvement in cognition and global/functional assessments comparing treatment to placebo.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Global Statistical Test (GST) Score
Time Frame: Baseline and Week 26

The Global Statistical Test (GST) score is a composite of cognition and function, calculated as the average of two change from baseline z-scores; the z-scores are calculated for the change from baseline scores for cognition (Alzheimer's Disease Assessment Scale-Cognitive Subscale [ADAS-Cog11]; lower value indicates improvement) and function (Alzheimer's Disease Cooperative Study - Activities of Daily Living, 23-item version [ADCS-ADL23] score; higher value indicates improvement).

GST is a standardized score relative to the population mean. Therefore, a GST score of 0 is representative of the population mean. Since GST is a composite of two endpoints, a negative ADCS-ADL23 score is used in deriving GST. Therefore, a lower score indicates improvement, and a higher score indicates worsening. There are no defined clinically relevant thresholds for this GST score.
Baseline and Week 26

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Alzheimer's Disease Assessment Scale-Cognitive Subscale 11 (ADAS-Cog11) Change From Baseline
Time Frame: Baseline and Week 26
The ADAS-Cog11 was designed to measure cognitive symptom change in participants with Alzheimer's Disease (AD) and consisted of 11 tasks. The standard 11 items (and corresponding score range) were: word recall (0-10), commands (0-5), constructional praxis (0-5), naming objects and fingers (0-5), ideational praxis (0-5), orientation (0-8), word recognition (0-12), spoken language ability (0-5), comprehension of spoken language (0-5), word-finding difficulty (0-5), and remembering test instructions (0-5). The test included 7 performance items and 4 clinician-rated items. The ADAS-Cog11 total score was the sum of all 11 individual items, with a total score ranging from 0 (no impairment) to 70 (severe impairment). Higher scores indicated more severe cognitive impairment. Baseline was defined as Day 1.
Baseline and Week 26
Alzheimer's Disease Cooperative Study - Activities of Daily Living, 23-Item Version (ADCS-ADL23) Change From Baseline
Time Frame: Baseline and Week 26
The ADCS-ADL23 is a 23-item assessment of functional impairment in terms of activities of daily living administered to the support person/caregiver. It comprises 23 questions about the subject's involvement and level of performance across items representing daily living. The questions range from basic to instrumental activities of daily living. Each item is rated from the highest level of independent performance to complete loss. The total score range is from 0 to 78, with lower scores indicating greater functional impairment. Baseline was defined as Day 1.
Baseline and Week 26
Plasma Neurofilament Light Chain (NfL) Concentrations Change From Baseline
Time Frame: Baseline and Week 26
Neurofilament light chain (NfL) is an objective biomarker of neurodegeneration and was measured to quantitatively support the evaluation of ATH-1017. Higher concentrations of NfL in plasma are associated with neurodegeneration.
Baseline and Week 26
