Chronic Subdural Hematoma Treatment With Intra-Arterial Bevacizumab Injection

Phase 1

Recruiting

• Conditions: Chronic Subdural Hematoma
• Interventions: Drug: Bevacizumab 4 mg/kg; Drug: Bevacizumab 2 mg/kg

• Registration Number: NCT06510582
• Lead Sponsor: The Cooper Health System

Brief Summary

The goal of this clinical trial is to test whether infusing bevacizumab into the middle meningeal arteries can be used to treat chronic subdural hematomas (cSDH).

The main questions it aims to answer are:

* Is bevacizumab infusion safe in cSDH patients?

* Is bevacizumab infusion effective in treating cSDH?

Recruitment & Eligibility

• Status: RECRUITING
• Sex: All
• Target Recruitment: 140

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.
• Coagulation abnormalities, including platelet count <100,000 and/or international normalized ratio of <1.5 despite attempts for correction.
• 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.

Primary Outcome Measures

Name	Time	Method
Number of Participants with Serious Adverse Events	Up to 3 months after study treatment	Reported serious adverse events classified using MedDRA and CTCAE, in addition to treatment-related events and all other adverse events

Secondary Outcome Measures

Name	Time	Method
Rate of Hematoma Recurrence	3 months after study treatment and 6 months after study treatment	Rate of hematoma recurrence or progression requiring intervention and/or readmission
Rate of Complete Hematoma Resolution	3 months after study treatment and 6 months after study treatment	Rate of complete hematoma resolution compared to baseline on imaging
Rate of Partial Hematoma Resolution	3 months after study treatment and 6 months after study treatment	Rate of at least 50% or greater reduction in hematoma size from baseline on imaging
Change in Hematoma Size	3 months after study treatment and 6 months after study treatment	Change in hematoma size measured in millimeters on imaging
Change in Clinical Neurological Symptom Scale Scores: NIHSS	3 months after study treatment and 6 months after study treatment	Change in National Institutes of Health Stroke Scale (NIHSS) scores, scores range from 0 to 42, with higher scores indicating more severe neurological deficit
Change in Clinical Neurological Symptom Scale Scores: GCS	3 months after study treatment and 6 months after study treatment	Change in Glasgow Coma Scale (GCS) scores, ranging from 3 to 15 with lower score indicating more impaired consciousness
Change in Clinical Neurological Symptom Scale Scores: mRS	3 months after study treatment and 6 months after study treatment	Change in modified Rankin Scale (mRS) scores, ranges from 0-6 with higher score indicating worse functional outcome
