NCT Number
A unique identification code assigned to every clinical trial registered on ClinicalTrials.gov (format: NCT followed by 8 digits). NCT numbers are permanent references for finding detailed trial information and are displayed alongside clinical trial data on PeptideTrace compound pages.
Technical Context
ClinicalTrials.gov was established in 2000 under the FDA Modernization Act of 1997. Registration became mandatory for most clinical trials involving FDA-regulated products under the FDA Amendments Act of 2007 (FDAAA 801). The International Committee of Medical Journal Editors (ICMJE) requires trial registration as a condition of publication. Each NCT record contains: study identification, design information, eligibility criteria, outcome measures, sponsor/collaborator, recruitment status, results (when available), and responsible party contacts. PeptideTrace's ClinicalTrials.gov sync pipeline queries the API v2 across all 185 compounds every 23 hours, tracking 13,223 trials across 132 compounds in steady state. The NCT number is the permanent link between PeptideTrace trial data and the full ClinicalTrials.gov record.
