Mild Cognitive Impairment Trials in the USA, 2026
Every industry-sponsored study on the ClinicalTrials.gov registry that lists a US site and is open, about to open, active-but-closed, or enrolling by invitation. This deliberately excludes academic and other non-industry sponsors — the full US registry across all sponsors runs to over 22,000 recruiting studies alone.
About this register
This register is built from ClinicalTrials.gov, the trial registry run by the U.S. National Library of Medicine.
