Clinical trial overview
The main study in the source data is NCT04918173, a Phase 3 interventional trial of Human Plasma Derived Antithrombin for patients with congenital antithrombin deficiency who are undergoing surgery or delivery.[1]
The study title says it is looking at the efficacy of Atenativ in this patient group, and the brief summary says the main objective is to assess clot-related events during surgical procedures or childbirth.[1]
Who the trial is for
The trial targets people with congenital antithrombin deficiency, which means the condition is present from birth.[1]
It is focused on patients who are having surgical procedures or parturition, which is the medical word for giving birth.[1]
This makes the study especially relevant for a specific high-risk group rather than for all patients with the condition.[1]
Treatment and study design
The study is listed as an interventional trial, which means the researchers are giving a treatment and measuring what happens.[1]
The intervention is Human Plasma Derived Antithrombin, listed in several country-specific product names for Atenativ, all given by intravenous infusion.[1]
The source data does not describe a comparison group in the text provided, so the main focus here is on the treatment group being observed during surgery or delivery.[1]
What the trial measures
The primary outcome is the incidence of a composite of thrombotic events and thromboembolic events.[1]
In simple terms, the study counts clot-related problems, combining more than one type of event into one main result.[1]
The outcome is measured under cover of Atenativ for surgical procedures or parturition, and it is tracked up to 30 days after treatment initiation.[1]
Trial status and size
The study status is listed as Authorised.[1]
The enrollment is 46, meaning 46 participants are planned or included in the study record provided.[1]
Because only one trial is provided in the source data, the evidence base here is limited to this single Phase 3 study.[1]
