Trial Outcomes & Findings for A Study of Subcutaneous Bevacizumab in Relapsed / Progressive Glioblastoma (NCT NCT02157103)

NCT ID: NCT02157103

Last Updated: 2018-05-17

Results Overview

To describe MRI response regarding edema and enhancement of glioblastoma and radiation-related brain enhancement when treated with subcutaneous bevacizumab daily. The therapeutic benefit of bevacizumab as regards glioblastoma multiforme (GBM) is largely due to the normalization of brain vasculature. This normalization appears on contrast-enhanced MRI as a reduction in enhancement and reduction in edema. For purposes of this study, any reduction in enhancement/edema by 25% or more will be considered a response.

SECONDARY outcome

Timeframe: During first 3 weeks of study

Subcutaneous bevacizumab may have toxicities unique to the subcutaneous administration and not seen with intravenous bevacizumab. During the first 3 weeks we will watch for such toxicities. Toxicities will be described and graded using the Common Toxicity Criteria for Adverse Effects (CTCAE) v3.

0 Toxicities

SECONDARY outcome

Timeframe: Within 2 months of starting intravenous bevacizumab

Population: One patient did not switch to standard of care intravenous bevacizumab.

Participants may switch from subcutaneous bevacizumab on study to standard of care intravenous bevacizumab. In these participants, we will measure decrease of edema after this switch. A further decrease in edema after making this switch would suggest intravenous to be superior to subcutaneous as regards decreasing edema. The therapeutic benefit of bevacizumab as regards GBM is largely due to the normalization of brain vasculature. This normalization appears on contrast-enhanced MRI as a reduction in edema. For purposes of this study, any reduction in edema by 25% or more will be considered a response.
