Brief Summary:
This study is designed to evaluate treatment effects of fosgonimeton (ATH-1017) in mild to moderate Alzheimer's subjects 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

Detailed Description:
This study is designed to assess the correlation of the functional translational biomarker P300 latency and change in ADAS-Cog11 induced by ATH-1017 therapy, over 26-week randomized, double-blind treatment.

Ages Eligible for Study:   55 Years to 85 Years   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Key Inclusion Criteria:

  • Age 55 to 85 years
  • Mild-to-moderate AD dementia subjects, MMSE 14-24, CDR 1 or 2 at Screening
  • Clinical diagnosis of dementia, due probably to AD, by Revised National Institute on Aging-Alzheimer's Association criteria (McKhann, 2011)
  • Reliable and capable support person/caregiver
  • Treatment-free or receiving stable acetylcholinesterase inhibitor (AChEI) treatment, defined as:

    • Treatment-naïve, OR
    • Subjects are on a stable, approved dose of an AChEI (except for donepezil at 23 mg PO) for at least 3 months before Screening OR
    • Subjects who received an AChEI in the past and discontinued 4 weeks prior to Screening

Key Exclusion Criteria:

  • History of significant neurologic disease, other than AD, that may affect cognition, or concurrent with the onset of dementia
  • History of unexplained loss of consciousness, and epileptic fits (unless febrile)
  • Subject has atypical variant presentation of AD, if known from medical history, particularly non-amnestic AD
  • History of brain MRI scan indicative of any other significant abnormality
  • Hearing test result considered unacceptable for auditory ERP P300 assessment
  • Diagnosis of severe major depressive disorder even without psychotic features
  • Significant suicide risk
  • History within 2 years of Screening, or current diagnosis of psychosis
  • Myocardial infarction or unstable angina within the last 6 months
  • Clinically significant (in the judgment of the investigator) cardiac arrhythmia (including atrial fibrillation), cardiomyopathy, or cardiac conduction defect (note: pacemaker is acceptable)
  • Subject has either hypertension (supine diastolic blood pressure > 95 mmHg), or symptomatic hypotension in the judgment of the investigator
  • Clinically significant ECG abnormality at Screening
  • Renal insufficiency (serum creatinine > 2.0 mg/dL)
  • Hepatic impairment with alanine aminotransferase or aspartate aminotransferase > 2 times the upper limit of normal, or Child-Pugh class B and C
  • Malignant tumor within 3 years before Screening
  • Memantine in any form, combination or dosage within 4 weeks prior to Screening
  • Donepezil at 23 mg PO
  • The subject has received active amyloid or tau immunization (i.e., vaccination for Alzheimer's disease) at any time, or passive immunization (i.e., monoclonal antibodies for Alzheimer's disease) within 6 months of Screening
