DSC-MRI in Measuring rCBV for Early Response to Bevacizumab in Patients With Recurrent Glioblastoma

May 1, 2026 updated by: ECOG-ACRIN Cancer Research Group

Change in Relative Cerebral Blood Volume as a Biomarker for Early Response to Bevacizumab in Patients With Recurrent Glioblastoma

This phase II trial studies how well dynamic susceptibility contrast-enhanced magnetic resonance imaging (DSC-MRI) works in measuring relative cerebral blood volume (rCBV) for early response to bevacizumab in patients with glioblastoma that has come back. DSC-MRI may help evaluate changes in the blood vessels within the cancer to determine a patient?s response to treatment.

Detailed Description

PRIMARY OBJECTIVES:

I. To determine whether binary changes (increase versus [vs.] decrease) in rCBV within enhancing tumor from baseline to 2 weeks after initiation of anti-angiogenic therapy is associated with overall survival (OS).

SECONDARY OBJECTIVES:

I. To determine whether the baseline pre-treatment rCBV measure alone is associated with OS.

II. To determine whether binary changes (increase vs. decrease) in rCBV within enhancing tumor from baseline to 2 weeks after initiation of anti-angiogenic therapy is associated with progression-free survival (PFS).

III. To determine whether changes in rCBV as a continuous variable within enhancing tumor from baseline to 2 weeks after initiation of anti-angiogenic therapy is associated with OS or PFS.

IV. To determine the association between rCBV and OS when adjusting for the changes in enhancing tumor volume.

V. To determine whether baseline cerebral blood flow (CBF) or change in CBF is associated with OS or PFS.

OUTLINE:

Patients undergo DSC-MRI within 3 days before bevacizumab initiation and at day 15.

After completion of study intervention, patients are followed up every 3 months for 1 year and then every 6 months for up to 4 years.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

  • Histologically proven intracranial glioblastoma or gliosarcoma at initial surgery

    • Patients will be eligible if the original histology was low-grade glioma and a subsequent diagnosis of glioblastoma or gliosarcoma is made (high-grade transformation)
  • Karnofsky performance status >= 70
  • Women must not be pregnant or breast-feeding
  • Progression of disease assessed by local site using Revised Assessment in Neuro-Oncology (RANO) criteria, with plan to give whole-dose bevacizumab therapeutically, either as single therapy or in conjunction with other chemotherapeutic regimens; patients getting bevacizumab to support additional radiation therapy or immunotherapy, or primarily for reduction of edema rather than for tumor treatment, are excluded; this must be the patient?s initial recurrence
  • Patient must not have been treated previously with immunotherapies (vaccines, checkpoint inhibitors, T-cells)
  • Intratumoral hemorrhage (acute, subacute, or chronic) as seen on hemosiderin-sensitive (gradient-echo) MRI may preclude patient inclusion because of anticipated limited evaluation due to magnetic susceptibility artifact on the heavily T2-weighted DSC-MRI images; if the region of enhancing tumor not affected by blooming artifact on the hemosiderin-sensitive images does not meet the 10 x 10 x 10 mm ?measurable enhancement? threshold specified elsewhere, the patient is ineligible
  • Progressive enhancement (> 25% increase in contrast enhancing volume compared to nadir) on MRI within 14 days of registration, >= 42 days since completion of radiation/temozolomide therapy, and >= 28 days since surgical resection or cytotoxic chemotherapy; measurable enhancement is defined as two perpendicular in-plane diameters of at least 10 mm and at least 10 mm in the 3rd orthogonal direction

  • Patients must be able to tolerate brain MRI scans with dynamic intravenous gadolinium-based contrast agent injections

    • Ability to withstand 22 gauge intravenous (IV) placement
    • No history of untreatable claustrophobia
    • No magnetic resonance (MR) incompatible implants/devices or metallic foreign bodies

    • No contraindication to intravenous contrast administration

      • Adequate organ function, including adequate renal function defined as estimated glomerular filtration rate (eGFR) >= 40 mL/min/1.73 m^2 as calculated per institution standard of care, and meeting local site requirements for intravenous administration of gadolinium-based MRI contrast agents
    • No known allergy-like reaction to gadolinium or moderate or severe allergic reactions to one or more allergens as defined by the American College of Radiology (ACR); patient may be eligible if willing to undergo pre-treatment as defined by the institution's policy and/or ACR guidance
    • Weight compatible with limits imposed by the MRI scanner table
  • Patient must be scheduled to receive treatment with a standard dose regimen of bevacizumab (bevacizumab infusion on days 1 and 15 of a 28-day treatment cycle); patient can be treated with bevacizumab alone or in combination with other chemotherapies Exclusion Criteria: (see Inclusion Criteria)

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Change in rCBV within enhancing tumor
Time Frame: Baseline to 2 weeks
Will determine whether binary changes (increase vs. decrease) in rCBV is associated with OS. Kaplan-Meier survival curves will be generated for both the increased and the decreased rCBV groups. The median survival time of both groups will be estimated and compared with a two-sided log rank test. Univariate Cox proportional hazards model will be used to test the association between changes in rCBV from baseline to 2 weeks and OS or PFS.

OS
Time Frame: Up to 5 years
Will determine if binary changes (increase vs. decrease) in rCBV is associated with OS. The median survival time of both groups will be estimated and compared with a two-sided log rank test.

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
