Trial Design

Duke Aging Center has a website on the 5Ts framework — a tool to help researchers employ best practices in the inclusion of older adults in their research studies.

This review article presents a framework for advance care planning clinical trials that are embedded into existing health care.

This article provides a framework for planning disclosure and consent procedures for research studies involving participants with dementia.

This article describes a validated two-step process for recruiting asymptomatic amyloid-positive individuals into clinical trials. The process was tested using cohorts from three Alzheimer’s studies (ADNI-MCI, ADNI-CN and INSIGHT). During a pre-screening phase, researchers pre-selected a subset of individuals who were more likely to be amyloid positive, based on the automatic analysis of data acquired during routine clinical practice, before doing a confirmatory PET scan for these selected...

The rarity of disorders caused by frontotemporal lobar degeneration (FTLD) leads to recruitment challenges for related clinical trials and difficulties with adequate power to detect treatment effects. The authors of this systematic review recommend developing personalized endpoints that are most clinically meaningful to individuals and their families, devising more powerful approaches to analyzing heterogeneous clinical and magnetic resonance imaging data, and developing new fluid biomarkers and...

This article describes the study design of a dual-objective, Phase III clinical trial in individuals presymptomatic for Alzheimer’s disease. It addresses the particular challenges for delay and prevention studies. These include: Ensuring that the trial population, cognitively normal at outset, contains a sufficient number of participants at increased risk of cognitive impairment onset during the trial time frame to avoid prohibitive trial size and duration. Finding appropriate measures to detect...

Researchers tested a two-step process for recruiting asymptomatic, amyloid-positive individuals into clinical trials.

This paper describes the design and development of a tablet-based decision support tool to enhance shared decision making and decisional capacity for people with a genetic condition that causes development problems and cognitive impairment who are participating in the informed consent process.

This online tool helps patient groups and clinical research sponsors identify high-value opportunities for patient engagement.

This case study examines how the use of community engagement principles and approaches enhanced clinical trial recruitment and retention. The Meharry Vanderbilt Community Engaged Research Core (CERC), which facilitates community involvement in clinical and translational research, was consulted to enhance participation of African-American women in a clinical trial. CERC's key recommendations included: 1) convene a Community Engagement Studio, 2) redesign the recruitment advertisement, 3) simplify...
