Phase II Avastin + Bortezomib for Patients With Recurrent Malignant Glioma

Phase II Trial of Avastin Plus Bortezomib for Patients With Recurrent Malignant Glioma

Primary Objective To estimate 6-month progression free survival probability of patients with recurrent glioblastoma multiforme treated with bortezomib plus Avastin. This efficacy assessment will be made separately among patients on enzyme-inducing anti-epileptic drugs and non enzyme-inducing anti-epileptic drugs.

Secondary Objectives To evaluate safety & tolerability of bortezomib plus Avastin among patients with recurrent malignant glioma.

To evaluate radiographic response, progression free survival & overall survival of patients with recurrent malignant glioma treated with bortezomib plus Avastin

Study Overview

• Status: Completed
• Conditions: Glioblastoma; Gliosarcoma
• Intervention / Treatment: Drug: Avastin; Drug: Bortezomib

Detailed Description

This is an open-label, 2-arm Phase II study assessing safety & efficacy of bortezomib in combination with Avastin for patients with recurrent glioblastoma multiforme (gbm). 56 total patients with recurrent WHO grade IV malignant gliomas have been enrolled on study. Avastin was administered intravenously at a dose of 15 mg/kg every 3 weeks. Bortezomib was administered on days 1, 4, 8, 11, 22, 25, 29, & 32 of a 42-day cycle. The dose of bortezomib was 1.7 mg/m2 for non-EIAED patients & 2.5 mg/m2 for EIAED patients. Treatment continued until either evidence of progressive disease, unacceptable toxicity, non-compliance with study follow-up / withdrawal of consent. Brain MRIs were obtained after every cycle.

Bortezomib administration is associated with mild toxicity in most patients, such as fatigue, diarrhea & nausea, constipation & peripheral neuropathy. Less common, bortezomib administration leads to more significant hematologic toxicities & peripheral neuropathies. Most significant toxicities associated with Avastin in recently completed phase II clinical trial at Duke were thrombotic complications & grade 2 proteinuria. "Unacceptable" toxicities rates of 15 percent or less were considered desirable, while rates of 40 percent or greater were considered undesirable. The statistical hypothesis that needed testing differentiated between 15% & 40% rate of unacceptable toxicity.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
6-month Progression-free Survival (PFS)	Percentage of participants surviving six months from the initiation of treatment without progression of disease. PFS was defined as the time from the initiation of treatment to the date of the first documented progression according to the Macdonald criteria, or to death due to any cause. Per Macdonald, progression is a ≥ 25% increase in the sum of the products of perpendicular diameters of enhancing lesions, any new lesion or clinical deterioration.	6 months

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Median Progression Free Survival (PFS)	Time in months from the start of study treatment to the date of first progression according to Macdonald criteria, or to death due to any cause. Per Macdonald, progression is a ≥ 25% increase in the sum of the products of perpendicular diameters of enhancing lesions, any new lesion, or clinical deterioration. Patients alive who had not progressed as of the last follow-up had PFS censored at the last follow-up date. Median PFS was estimated using a Kaplan-Meier curve.	Time in months from the start of study treatment to the date of first progression or death. Assessed up to 60 months.
Median Overall Survival (OS)	Time in months from the start of study treatment to the date of death. Patients alive as of the last follow-up had OS censored at the last follow-up date. Median OS was estimated using a Kaplan-Meier curve.	Time in months from the start of study treatment to date of death due to any cause. Assessed up to 60 months.
Radiographic Response Rate	The percentage of participants with a complete or partial response at any assessment as determined by the Macdonald criteria. A confirmation of response was not required. Per Macdonald criteria, complete response (CR) was the disappearance of all target lesions and partial response (PR) was a ≥50% decrease in the sum of the longest diameter of target lesions, no new lesions and stable or decreasing steroid dose. Objective response =CR+PR. Tumor assessments were done at baseline and at the end of each 6 week treatment cycle, and overall best response was recorded.	60 months
Number of Patients With Grade 3 or Greater, Treatment-related, Non-hematologic Toxicities	Number of patients with grade 3 or greater, treatment-related, non-hematologic toxicities based on Common Terminology Criteria for Adverse Events (CTCAE) version 3.0.	60 months
