Wednesday, October 24, 2018 The CCTG CEC.5 trial: A Phase II Study of Corticosteroid + Bevacizumab vs Corticosteroid + Placebo (BeST) for Radionecrosis after Radiosurgery for Brain Metastases has officially closed to accrual as of October 12, 2018. Primary Objective: To investigate whether the addition of bevacizumab to standard corticosteroid therapy results in greater improvement in symptoms (clinical and patient-reported symptom improvement associated with radionecrosis and less radionecrosis treatment-induced symptoms) compared with standard corticosteroid therapy. Secondary Objectives: To evaluate the toxicity profile associated with bevacizumab and corticosteroid therapy.To compare self-reported health related quality of life (HRQOL) using LASA, Dexamethasone Symptoms Questionnaire-Chronic (DSQ-C), and MDASI-BT symptom and interference score between treatment arms.To compare intracranial progression-free survival and time to maximum radiographic response between treatment arms.To compare the dose and duration of corticosteroid required between treatment arms and correlate steroid requirement with DSQ-C and MDASI-BT scores.Correlative Objectives:To explore serum/urine/imaging biomarkers that predict for treatment response.
