Alzheimers Dement
December 2024
Massachusetts General Hospital, Harvard Medical School, Boston, MA, USA.
Background: The ability to monitor cognitive trajectories over the course of trials can provide valuable insights into treatment efficacy. However, existing trial methods are limited in monitoring cognition in real-time and at high frequencies. Gameplay-based assessments hold promise as complementary cognitive tools.

Alzheimers Dement
December 2024
Washington University School of Medicine, St. Louis, MO, USA.
Background: The well-accepted statistical efficacy inference approach for Alzheimer's disease (AD) clinical trials compares the absolute difference in change from baseline at the last study visit using MMRM (henceforth referred to as MMRM-Last-Visit). Recent AD clinical trials have shown that treatment effects may be manifested prior to 18 months. The objective is to evaluate models estimating an overall treatment effect across all post-baseline visits that may characterize disease modifying effects in contemporary early AD clinical trials.

Alzheimers Dement
December 2024
Center for Health + Technology, University of Rochester Medical Center, Rochester, NY, USA.
Background: In preparation for therapeutic trails involving patients with Alzheimer's disease (AD) and mild cognitive impairment (MCI), there is a need for valid, disease-specific caregiver-reported outcome (CRO) measures capable of tracking symptomatic burden in response to therapy over time. CROs are useful tools in clinical trials for individuals with AD, MCI, and dementia who are unable to self-report. In addition, CROs are accepted by the United States Food and Drug Administration to support regulatory claims.

Alzheimers Dement
December 2024
Chitkara College of Pharmacy, Chitkara University, Rajpura, Punjab, India.
Background: Various studies have evidenced the neuroprotective role of SIRT1 activator. However, whether SIRT1 activator, Piceatannol pharmacological treatment is protective in chronic unpredictable stress induced memory dysfunction remains unknown. Therefore, this study design included testing the hypothesis that Piceatannol administered in chronic unpredictable stress induced memory dysfunction mice shows protective effects, explores & probes underlying the activation of SIRT1 pathway.
View Article and Find Full Text PDFBackground: Clinical outcome assessments (COAs) that measure functional capacities are key tools to evaluate efficacy in Alzheimer's disease (AD) clinical trials. The Alzheimer's Disease Cooperative Study Activities of Daily Living (ADCS-ADL) scale is frequently used to assess changes in both basic and instrumental activities of daily living, but there is no clear consensus on what magnitude of change on this scale may be considered clinically meaningful. To address this question, we conducted anchor-based analyses (as recommended by the FDA) to explore meaningful within-patient/participant change thresholds on the ADCS-ADL.
