Joint injection shows promise for stopping repeat bleeds in hemophilia
NCT ID NCT07187661
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested whether injecting bevacizumab (a drug that blocks blood vessel growth) into the joints of people with hemophilia can prevent repeated bleeding episodes. Eighteen participants with chronic synovitis (joint inflammation) received the injection. Researchers measured changes in bleeding rates, joint health, and MRI scans over three months to see if the treatment reduced bleeds and improved joint 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 (Avastin), a drug that blocks blood vessel growth
- What this could lead to
- If it works, this could offer a new way to reduce painful joint bleeds and improve joint health in people with hemophilia.
- What could go wrong
- This is a very small, early study with only 18 people and no comparison group. The effects may not be confirmed in larger trials, and there is a risk of side effects from the injection or the drug itself.

Inclusion Criteria: * Confirmed diagnosis of Hemophilia A. * Presence of one or more target joints (knee, elbow, ankle) with chronic synovitis and a history of \>2 hemarthrosis episodes in the past 6 months. * Target joint World Federation of Hemophilia (WFH) joint score of 2-3. * Adequate hematological, renal, and liver function (as specified by protocol lab values). * Ability and willingness to provide informed consent and comply with the study protocol. Exclusion Criteria: * HIV positive diagnosis. * Severely damaged joints or anatomical limitations preventing safe injection. * Contraindications to MRI. * Uncontrolled hypertension. * Recent major surgery/trauma (\<28 days). * Serious non-healing wound, active cardiovascular disease, or other significant comorbidities that could increase risk or interfere with the study.
