Can a cancer drug curb severe bleeding in a rare genetic disorder?
NCT ID NCT07772050
First seen Aug 19, 2026 · Last updated Aug 20, 2026 · Updated 1 time
Summary
This study looks back at the medical records of 244 adults in France with hereditary hemorrhagic telangiectasia (HHT), also called Rendu-Osler disease, who were treated with the drug bevacizumab. The goal is to describe how the drug was used and to measure its impact on bleeding, as reflected by the number of red blood cell transfusions and hemoglobin levels. By analyzing real-world data from 2009 to 2024, researchers hope to better understand the drug's potential benefits for managing this condition.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- bevacizumab (an anti-VEGF antibody)
- What this could lead to
- If successful, this analysis could strengthen the evidence for using bevacizumab to reduce bleeding and transfusion needs in people with HHT.
- What could go wrong
- This is a retrospective review, not a controlled trial, so it cannot prove cause and effect. Results may be influenced by patient selection and missing data.
