Clinical trials overview
One authorised Phase 3 interventional study is testing VGA039 in people with von Willebrand Disease.[1]
The study is designed to assess the effect of subcutaneous VGA039 prophylaxis, which means preventive treatment given under the skin, on bleeding events.[1]
Who the study is for
The trial is for adolescent and adult patients with von Willebrand Disease.[1]
It focuses on people who previously did not receive von Willebrand Factor-containing concentrates on a prophylactic basis, meaning they did not use these products regularly to prevent bleeding.[1]
What the trial measures
The main endpoint is annualized bleeding rate (ABR).[1]
ABR is a way to measure how many bleeding events happen over one year, so researchers can see whether the treatment helps reduce bleeding.[1]
Trial status and size
The study status is Authorised, which means it has been allowed to start.[1]
The planned enrollment is 54 participants.[1]
What this means for patients
This trial is part of clinical research to learn whether VGA039 can help prevent bleeding in a specific group of people with von Willebrand Disease.[1]
Because it is a Phase 3 study, the researchers are studying the treatment in a larger group to better understand its benefit in real patients.[1]
