Treatment of chronic subdural hematoma using bevacizumab injection

Chronic Subdural Hematoma Treatment With Avastin® (Bevacizumab) Intra-Arterial Injection: A Non-Randomized, Open-Label Phase 1/2 Clinical Trial

Phase1; Phase2 Interventional The Cooper Health System · NCT06510582

This study is testing if injecting a medication called bevacizumab into the arteries can help adults with chronic subdural hematomas feel better and clear up the blood buildup.

What this trial studies

This clinical trial aims to evaluate the safety and effectiveness of infusing bevacizumab into the middle meningeal arteries for treating chronic subdural hematomas (cSDH). It involves administering two different doses of bevacizumab to adult patients with radiographic evidence of cSDH. The study will assess whether this approach can improve patient outcomes and reduce the persistence of subdural blood. Participants will be monitored for any adverse effects and the overall efficacy of the treatment.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older with radiographic evidence of chronic subdural hematoma persisting for more than 10 days after an injury.

Not a fit: Patients with other intracranial pathologies, recent surgeries, or known hypersensitivity to bevacizumab may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could provide a new, less invasive option for managing chronic subdural hematomas.

How similar studies have performed: While the use of bevacizumab in this context is novel, similar approaches in treating other conditions have shown promise.

Eligibility criteria

Inclusion Criteria:

* Adult patients (≥18 years)
* Radiographic evidence of chronic subdural hematoma, including

  1. Persistence of subdural blood more than 10 days after index traumatic injury or event
  2. Presence of mixed density blood
  3. Presence of subdural membranes
* Can obtain informed consent and Health Insurance Portability and Accountability Act (HIPAA) authorization.

Exclusion Criteria:

* Pregnant, breastfeeding, or unwilling to practice contraception during participation in the study.
* Patients with concomitant intracranial pathology other than subdural hematoma (e.g., intracranial malignancy).
* Patients with known hypersensitivity to bevacizumab.
* Patients with radiographic evidence of mass effect.
* Patients have focal neurological deficits attributed to subdural hematoma.
* Patient had craniotomy or burr hole operative procedures performed in preceding two weeks prior to onset of subdural hematoma.
* Secondary causes apart from trauma for the chronic subdural hematoma, such as underlying vascular abnormality or tumor.
* Emergent surgical evacuation is required for the patient.
* Non-convexity chronic subdural hematoma, as the middle meningeal artery will not supply this area.

* Patients with known contraindications for angiography. Patients with contrast allergy will be premedicated with diphenhydramine and steroids.
* Patient has known active systemic infection or sepsis.
* Patient has contradiction to anesthetic agents used for conscious sedation/monitored anesthesia care (MAC).
* Patient has life expectancy of less than six months due to comorbid terminal conditions.
* Patient has a premorbid modified Rankin score (mRS) of 5 or greater.
* Concurrent participation in another research protocol for investigation of an experimental therapy.
