One record for each name ClinicalTrials.gov classes as industry on a trial, as lead sponsor or collaborator, from its data of 13 Nov 2026. Each lists the company's trials with its role, phase, status and posted results; the drugs its trials test, by trial links that passed automated checks, with the highest phase registered and each drug's targets; the conditions its trials study; and the other organizations its trials name. A phase is as registered, not a stage of development.
A company's name or ID; a trial's NCT number, for the companies it names; or a drug's name or ChEMBL ID, for the companies whose trials test it. Case and punctuation do not matter. Other words find the companies whose names hold a word that starts with each.
18,985 companies from ClinicalTrials.gov.
