A trial with sites in more than one country appears in each of those registers.
Everything on this page is copied from public ClinicalTrials.gov registry records — it is not written from memory, and nothing here describes how Bacillus Calmette-Guerin works or whether it is effective. Each trial links to its own record so you can check it yourself.
This page is built automatically: a daily sync job reads the registry records behind our country trial registers, collects every trial that lists Bacillus Calmette-Guerin (or a registered synonym) as a drug or biological intervention, and tabulates the registry fields directly. Placebos and generic comparators are excluded. There is no AI drafting and no per-compound editorial pass, and the page has not been clinically reviewed. The “last verified” date above is the timestamp of that sync, not a review date. Our general editorial approach is described in our editorial standards and corrections policy. The ClinicalTrials.gov data on this page was last retrieved on 24 Sep 2026.
