Clinical trial updates › About this data
Clinical trial updates
ClinicalTrials.gov is the US registry of clinical studies. Drug and device makers register their trials there and update the record as each study moves on. We list the studies that companies sponsor, and match the sponsor to a public company when the name lines up. The page opens on Phase 3 studies marked completed, the late-stage trials that come before a request for approval. Change View to see the changes of status we have noticed, or every recent update.
- Where it comes from

Who reports it: The sponsor of the study, in its record on ClinicalTrials.gov. The registry is run by the US National Library of Medicine and does not check what sponsors report.

- Coverage
- Studies with an industry sponsor or collaborator that were updated since 2015. The history of status changes starts on the day we first stored each study.
- Worth knowing
- A completed study is not a result: the registry says the study ended, not whether the treatment worked. Status changes start on the day we first stored each study, so earlier changes are not shown. Dates are the sponsor's own, and an estimated date can pass without an update. We match sponsors to companies automatically, with a hand-checked list for the large drugmakers, so a study with no ticker may still belong to a public company. This is information about studies, not a forecast of what they will show or of a stock's price.
