Primary Outcome Measures:
  • Change from baseline in Computerized neuropsychological test battery (cNTB) [ Time Frame: 26 weeks ]

Secondary Outcome Measures:
  • Change from baseline in Global Impression of Change (CGIC) [ Time Frame: 26 weeks ]
  • Change from baseline in Alzheimer's Disease Cooperative Study/Activities of Daily Living scale adapted for MCI patients (ADCS-MCI-ADL) [ Time Frame: 4, 13, 26 weeks ]
  • Change from baseline in Alzheimer's Disease Assessment Scale cognitive subscale (ADAS-cog14) [ Time Frame: 13, 26 weeks ]
  • Safety and tolerability of piromelatine [ Time Frame: 26 weeks ]
    Vital signs measurements (heart rate and blood pressure), reported AEs or SAEs, physical examinations results, clinical laboratory evaluations (hematology, biochemistry, and urinalysis), 12-lead ECGs results and Sheehan Suicidality Tracking Scale scores will be collected throughout the study.

Other Outcome Measures:
  • Change form baseline in Neuropsychiatric Inventory (NPI) scale [ Time Frame: 26 weeks ]
  • Change from baseline in Pittsburgh Sleep Quality Index (PSQI) [ Time Frame: 4, 13, 26 weeks ]
