Clinical Trials API

Stopped clinical trials with the stop reason classified. ClinicalTrials.gov records why a trial halted as free text; this reads that text and separates safety and efficacy failures from business, recruitment and funding stops, which are the ones people routinely misread as drug failures. Filter by sponsor, condition, intervention and phase, and get the cohort-level breakdown alongside the records.
