Every trial, status, phase and sponsor on this page is copied from public ClinicalTrials.gov records by a daily sync. Nothing here describes how Prolastin-C works or whether it is effective, and it is not medical advice.
Everything on this page is copied from public ClinicalTrials.gov registry records — it is not written from memory, and nothing here describes how Prolastin-C 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 Prolastin-C (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 1 Oct 2026. How every register is built: methodology · fixes we have made: corrections log.
