All clinical trial data is currently extracted from the Clinical Trials Transformation Initiative AACT database which is a publicly available relational database that contains all information (protocol and result data elements) about every study registered in ClinicalTrials.gov.
Currently, the Trials Annotator site only lists clinical trials matching certain criteria:
Several categories have been defined for the annotation effort:
Recruitment
Recruitment, a component of the consent process, is the process of distributing or presenting information that describes the research project and eligibility criteria so that a prospective subject may consider enrollment.
Enrollment
Occurs when an eligible, informed potential participant undergoes the initial informed consent process and voluntarily agrees to participate in a research project. Example: You enroll 100 to accrue 25. See also Accrual.
Screen failures
Subjects who consented to participate in research but who were disqualified during screening procedures.
Accrual
The number of subjects who have completed or are actively in the process of completing a study [...]. This does not include screen failures. It does include withdrawals. Example: You enroll 100 to accrue 25.
Withdrawals
Subjects who were accrued but later withdrew from the study, either before or after receiving a study drug, device or intervention. This does not include screen failures.
