How we track
Where the data comes from
Registered trials are pulled automatically every night from ClinicalTrials.gov (API v2). The programme register — which company is pursuing what, by which approach — is maintained by hand from peer-reviewed literature, regulatory filings and company disclosures.
What we verify by hand
A registered trial proves a sponsor declared a study. It does not prove the study is running, or that it will read out. Phase changes detected automatically are queued for review and only published once a human has confirmed them.
What we don't do
We don't rank treatments by expected efficacy, we don't predict launch dates, and we don't take payment to change a record. Programmes that fail stay in the register, marked discontinued — the history of failures is as informative as the history of successes.
Advertising and commercial links
Where we operate in the EU, Directive 2001/83/EC Article 88 prohibits direct-to-consumer advertising of prescription-only medicines, so we carry no commercial links to finasteride, dutasteride or any other prescription drug for European readers. Any paid link, when one exists, is disclosed on the page it appears on.
Reporting an error
A wrong record on a health site does real harm. If you spot one, tell us — corrections are handled ahead of everything else.
