From public ClinicalTrials.gov registrations. Sponsor and study level only: we never list investigators, contacts or participants. A registration describes a planned study and can change. Status changes are read from each study's current status, actual dates and latest posted update, not a full change history, so an update can be a correction rather than a new change. Verify on ClinicalTrials.gov.
