Recruiting PHASE3 Radiation Necrosis

Compares treatment options for Radiation Necrosis

Official title Bevacizumab Versus Corticosteroids as First-line Treatment in Patients With Symptomatic Cerebral Radiation Necrosis After Radiation for High-grade Glioma or Brain Metastases

ClinicalTrials.gov ID: NCT06888817

What this study is testing

What is Bevacizumab?

Bevacizumab is an investigational medicine, given as an once-daily infusion into a vein, being studied as a potential treatment for radiation necrosis.

Also referred to as Avastin, Anti-VEGF monoclonal antibody.

Plain-language explanation of the investigational treatment - it is being studied and is not an approved or proven therapy. The study team can confirm the details.

What it's testing
Cerebral radiation necrosis (CRN) is a severe complication of high-dose radiation for brain metastases (BM) or glioma, which can potentially cause significant neurologic symptoms leading to serious morbidity and impaired quality of life (QoL). The first-line therapy for symptomatic CRN (sCRN) is corticosteroids, primarily dexamethasone, which often leads to complications, refractory symptoms, and interference with anti-cancer treatment.
  • Phase 3: a large, late-stage study
  • Time commitment: about 12 weeks
  • Which group you join is decided by chance.
