  Purpose
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.

Arms Assigned Interventions
Experimental: bevacizumab + corticosteroids

The patient will receive bevacizumab 10 mg/kg IV given on days 1 and 15 of a 28 day cycle for 4 cycles. Once the patient has started the study treatment, the dose of corticosteroids will be tapered every 5 days (e.g., dexamethasone 2 mg or prednisone 15 mg per taper), as tolerated, under the management of the treating MD. If patients deteriorate while tapering, dexamethasone will be increased up to a maximum of 16 mg per day, as per treating MD, to manage symptoms.

Patients who meet the criteria for clinical progression will be treated as per treating MD.

Drug: bevacizumab
IV
Drug: corticosteroids
IV
Experimental: placebo + corticosteroids

The patient will receive placebo 0.9% NaCl volume equal to bevacizumab volume added to 100 mL bag of 0.9% NaCl delivered IV given on days 1 and 15 of a 28-day cycle for 4 cycles. Once the patient has started the study treatment, the dose of corticosteroids will be tapered every 5 days (e.g., dexamethasone 2 mg or prednisone 15 mg per taper), as tolerated, under the management of the treating MD. If patients deteriorate while tapering, dexamethasone will be increased up to a maximum of 16 mg per day, as per treating MD, to manage symptoms.

Patients who meet the criteria for clinical progression will be allowed to receive bevacizumab according to the protocol.

Detailed 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.

Ages Eligible for Study:   18 Years and older   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Criteria

Pre-Registration Eligibility Criteria:

  1. Patients who present with symptomatic brain radionecrosis after they have received radiosurgery for brain metastases from primary solid tumor including but not limited to lung, breast, colorectal cancer but excluding melanoma, choriocarcinoma, renal cell carcinoma or gliomas
  2. Patients at institutions that elect to utilize central imaging review to confirm eligibility must be pre-registered prior to submission of these images; images should be submitted as soon as possible after the pre-registration magnetic resonance imaging (MRI) is obtained; turnaround time for this review will be =< 72 business hours after receipt of images by the Imaging and Radiation Oncology Core (IROC)
  3. Patients at institutions that elect to confirm eligibility locally may be pre-registered at the same time as they are randomized

Registration/Randomization Eligibility Criteria:

  1. A diagnosis of radionecrosis will be based on a clinical onset of symptoms and radiological findings of radionecrosis at 3-24 months following radiosurgery, with or without pathological confirmation.

    1.1 'Symptomatic' brain radionecrosis to at least one lesion following radiosurgery treatment for brain metastases where 'symptomatic' is defined as:

    1.1.1 New or increasing headache associated with mass effect, sensory or motor abnormality, cognitive changes, speech difficulty, balance or coordination difficulty, cranial nerve deficits

    1.1.2 Symptoms are persistent or worsening despite administration of at least dexamethasone 4 mg (or equivalent corticosteroid) daily for 1 week

    1.2 Clinical eligibility supported by central imaging real-time review. The presence of at least the following conventional MR image characteristic:

    1.2.1 Conventional MR - Lesion quotient of < 0.3, where lesion quotient is defined as the proportional value of the maximum axial cross-sectional area of the T2-weighted defined lesion over the maximum axial cross-sectional area of the contrast-enhancing lesion on the T1-weighted post-gadolinium sequence on a comparable axial slice. If the conventional MR findings are not seen, the following dynamic susceptibility-contrast (DSC) MR characteristics may be used to meet eligibility for this study.

    1.2.2 DSC MR - The cut-offs below will be based on GRE EPI DSC perfusion images, acquired without using a gadolinium pre-load:

    1.2.2.1 Relative cerebral blood volume (rCBV) <1.5 in the enhancing- lesion relative to normal-appearing white matter (NAWM)

    1.2.2.2. Percentage of signal recovery (PSR) > 76%, where PSR is determined by comparing the lower signal intensity during passage of the contrast bolus with the post-contrast signal intensity on the signal intensity-time curve

    1.2.3 Centers that standardly use PET or MRS to determine a diagnosis of radionecrosis are permitted to use these modalities to assist in their patient selection; however the criteria described for conventional MR and/or DSC should also be met for study eligibility. Both PET and MRS are not mandatory for study eligibility.

  2. Prior to start of treatment

    2.1 Must have been taking a stable dose of corticosteroids for symptom management for at least 1 week before baseline MRI.

    2.2 No systemic therapy within 2 weeks prior to registration or plan for systemic therapy within the first 8 weeks after study registration. The protocol provides a list of 'approved systemic' therapies that are allowed for concurrent use with bevacizumab.

    2.3 No bevacizumab ≤ 3 months of study registration.

    2.4 Central imaging real-time review (72 hour turn around) to confirm eligibility.

  3. Not pregnant and not nursing, because this study involves an investigational agent whose genotoxic, mutagenic and teratogenic effects on the developing fetus and newborn are unknown.
