Examining the level of test burden in NIA’s Alzheimer’s disease and Alzheimer’s disease related dementias (AD/ADRD) clinical trials

The National Institute on Aging (NIA) is working to increase access of its AD/ADRD clinical trials (CT) into community health care settings. Concerns exist in the field regarding the feasibility of conducting AD/ADRD CTs outside of academic settings given the testing required within CT protocols. We evaluated recently awarded NIA CTs to document their types and frequency of diagnostic tests required. Findings provide NIA the opportunity to understand the potential test burden on sites and consented participants.
