Alzheimer Disease Clinical Trial
— DARIDOR-ALZOfficial title:
Daridorexant to Treat Insomnia in Patients With Mild Cognitive Impairment and Mild to Moderate Alzheimer Disease
DARIDOR-ALZ is a phase IV clinical trial designed to evaluate both the efficacy and safety of daridorexant, a selective dual orexin receptor antagonist that blocks the actions of the orexin neuropeptides at both orexin-1 and orexin-2 receptors, in selected populations of MCI and mild-to-moderate AD patients with insomnia complaints.

Secondary | Change in cognition | The Alzheimer's Disease Cooperative Study - Preclinical Alzheimer Cognitive (ADCS-PACC) scale score will be based on scores from the Mini Mental State Examination (MMSE) (range from 0-30 points), Free and Cued Selective Reminding Test - FCSRT (range from 0-48 points), the Digit Substitution Symbol Test, the Wechsler Intelligence Scale for Adults (WAIS-IV) (range from 0-93 points), the Clinical Dementia Rating Scale (CDR) (range from 0-18 points), and the 2-minute Verbal Fluency Test.
The ADCS-PACC will be measured at each visit. Each of the component change scores is divided by the baseline sample standard deviation of that component, to form standardized z scores. These z scores are summed to form the composite. Z Scores could range from -5 to +5 with higher scores indicating less deficit and lower scores indicating greater deficit. |
