This page is built automatically: a daily sync job reads the registry records behind our country trial registers, collects every trial that lists JNJ-87189401 (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 11 Nov 2026. How every register is built: methodology · fixes we have made: corrections log.
