NCT ID: NCT00612339

Last Updated: 2013-05-27

Basic Information

• Recruitment Status: COMPLETED
• Clinical Phase: PHASE2
• Total Enrollment: 41 participants
• Study Classification: INTERVENTIONAL
• Study Start Date: 2007-08-31
• Study Completion Date: 2012-05-31

Brief Summary

Primary objective- To determine efficacy of Avastin, 10 mg/kg every other week, in combination with standard 5-day temozolomide in terms of response rate.

Secondary objective- To determine safety of Avastin & Temozolomide in unresectable glioblastoma patients

Detailed Description

Subjects have histologically confirmed WHO gr IV primary malignant glioma that is unresectable/multifocal. This is Phase II study where up to 41 subjects will receive up to 4 cycles of Avastin & Temozolomide. Avastin administered at 10 mg/kg every 14 days beginning a minimum of 7 days after biopsy/28 days after craniotomy. Temozolomide dosed at 200 mg/m2 daily for 5 days in 28-day cycle. Patients will receive up to 4 cycles of Avastin & Temozolomide, then proceed with standard XRT. Study will use 2-stage "minimax" study design in which 21 subjects are accrued during 1st stage, with possibility that additional 20 patients accrued during 2nd stage. In initial Phase I & II trials, 4 potential Avastin-associated safety signals were identified: hypertension, proteinuria, thromboembolic events, & hemorrhage. Avastin-associated adverse events in Phase III trials include congestive heart failure, GI perforations, wound healing complications, & arterial thromboembolic events. Most common toxicity associated with Temozolomide has been mild myelosuppression.

Conditions

Study Groups

Avastin and Temozolomide

Avastin administered at 10 mg/kg every 2 weeks beginning a minimum of 7 days after biopsy or 28 days after craniotomy. Temozolomide dosed at 200 mg/m2 daily for 5 days in a 28-day cycle.

Group Type: EXPERIMENTAL

Avastin and Temozolomide

Intervention Type: DRUG

This is Phase II study with the combination of Avastin \& Temozolomide for unresectable or multifocal WHO grade IV malignant glioma patients. Patients will receive up to 4 cycles of Avastin \& Temozolomide . Avastin administered at 10 mg/kg every 14 days beginning minimum of 7 days after biopsy or 28 days after craniotomy. Temozolomide will be dosed at 200 mg/m2 daily x 5 days in 28-day cycle. Patients will have baseline MRI \& repeat MRI every 4 weeks. If there is no evidence of disease progression after each cycle, or unacceptable toxicity, or as determined by investigators, patient non-compliance or patient withdraws consent to continue therapy \& requests discontinuation, patients will receive up to 4 cycles of Avastin \& Temozolomide, then proceed with standard XRT therapy, \& future therapy after 4 cycles will be at discretion of patient \& treating physicians.
