Brief Summary:
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.

Condition or disease Intervention/treatment Phase
Alzheimer Disease Dementia of Alzheimer Type Drug: ATH-1017 Drug: Placebo Phase 2 Phase 3

Detailed Description:
The study is designed to evaluate safety and efficacy of ATH-1017 in mild to moderate AD subjects, with double-blind, 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.

Primary Outcome Measures :
  1. Overall treatment effect of ATH-1017 as reflected by the Global Statistical Test [ Time Frame: Week 26 ]
    The Global Statistical Test (GST) combines the scores from cognition (Alzheimer's Disease Assessment Scale-Cognitive Subscale [ADAS-Cog11]) and function (Alzheimer's Disease Cooperative Study-Activities of Daily Living, 23-item version [ADCS-ADL23] score)

Secondary Outcome Measures :
  1. Cognition [ Time Frame: Week 26 ]
    Alzheimer's Disease Assessment Scale-Cognitive Subscale [ADAS-Cog11] (Range of 0 to 70, where 0 is least impairment and 70 is most severe impairment)

  2. Clinical Global Impression of Change [ Time Frame: Week 26 ]
    Alzheimer's Disease Cooperative Study-Clinical Global Impression of Change [ADCS-CGIC] (Range of 1 to 7, where 1 is marked improvement and 7 is marked worsening)

  3. Activities of Daily Living [ Time Frame: Week 26 ]
    Alzheimer's Disease Cooperative Study - Activities of Daily Living, 23-item version [ADCS-ADL23] (Range of 0 to 78, where a higher score indicates greater function)
