Corticosteroids + Bevacizumab vs. Corticosteroids + Placebo (BEST) for Radionecrosis After Radiosurgery for Brain Metastases


Brief description of study

This randomized phase II study aims to investigate whether the addition of bevacizumab to standard corticosteroid therapy results in greater improvement in symptoms and less treatment-induced symptoms compared with standard corticosteroid therapy for patients with symptomatic brain radionecrosis following radiosurgery. It is hypothesized that the addition of bevacizumab to standard care corticosteroids will reduce treatment-induced toxicities and improve neurologic impairments in patients with brain radionecrosis following radiosurgery for brain metastases.

Detailed Study Description

This is a randomized double-blinded phase II study of corticosteroids with bevacizumab vs. corticosteroids with placebo for brain radionecrosis following radiosurgery for brain metastases. This is a two-arm clinical trial with parallel group design for longitudinal quality of life endpoint. Patients will be stratified according to age ( 65 years vs. > 65 years), pathological confirmation of necrosis (yes vs. no), MDASI-BT mean global score (symptom + interference scores) ( < 4.0 vs. > 4.0) and prior whole brain radiotherapy (yes vs. no). The primary and secondary objectives are detailed below.

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:

  1. To evaluate the toxicity profile associated with bevacizumab and corticosteroid therapy.
  2. 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.
  3. To compare intracranial progression-free survival and time to maximum radiographic response between treatment arms.
  4. To compare the dose and duration of corticosteroids required between treatment arms and correlate steroid requirement with DSQ-C and MDASI-BT scores.

Patient event monitoring will occur every 2 months after treatment up to 6 months. Then event monitoring will occur up to one year.
