Outcome Measures

Primary Outcomes (1)

  • Global Statistical Test (GST) Score at Baseline

    The Global Statistical Test (GST) score is a composite of the change from baseline (CFB) z-scores to Week 26 in the Alzheimer's Disease Assessment Scale - Cognitive Subscale, 13-Item Version (ADAS-Cog13; range 0-85; higher scores indicate greater impairment) and Event Related Potential P300 Latency (ERP P300; longer latency (milliseconds) indicates greater impairment). This composite approach was used to assess overall change in disease status and treatment effects of ATH-1017. The GST score was defined as a single outcome variable based on standardizing and combining individual patient-level z-score of change from baseline cognition (ADAS-Cog13) and ERP P300 latency scores. The between-group difference was calculated by subtracting the mean GST score for placebo from the mean GST score for ATH-1017. A negative value based on GST scores (ATH-1017 minus placebo) indicates a favorable response to ATH-1017, while a positive value favors placebo.

  • Moderate or severe substance abuse disorder (according to DSM-5)
  • Myocardial infarction or unstable angina within the last 6 months
  • Clinically significant cardiac arrhythmia (including atrial fibrillation), cardiomyopathy, or cardiac conduction defect (note: pacemaker is acceptable)
