Amgen 386 for Recurrent Glioblastoma

Status: Recruiting
Phase: Phase 1/Phase 2
Diagnosis: Brain/Neuro Cancer: Recurrent Glioblastoma
NCT ID: NCT01290263 (View complete trial on ClinicalTrials.gov)
DFCI Protocol ID: 12-185

 

Primary Objectives Cohort A ‐‐ monotherapy: To determine the efficacy of AMG 386 in participants with recurrent glioblastoma (GBM) as measured by 6‐month progression‐free survival (PFS6) Cohort B - combination therapy: Phase I To determine the maximum tolerated dose of AMG 386 in combination with bevacizumab given at 10mg/kg every 2 weeks in participants with recurrent glioblastoma. Phase II To determine the efficacy of AMG 386 plus bevacizumab in participants with recurrent glioblastoma (GBM) as measured by 6‐month progression‐free survival (PFS6). Secondary Objectives: To evaluate radiographic response in both cohort populations. To evaluate overall survival in both cohort populations. To assess time‐to‐progression in both cohort populations. To investigate the safety profile in both cohort populations. Exploratory Objectives: To evaluate expression of factors associated with tumor angiogenesis using a multiples cytokine assay among participants undergoing therapy with AMG 386 with response to therapy and development of resistance. This is an open‐label Phase I/II study of AMG 386 monotherapy and AMG 386 in combination with bevacizumab. Two cohorts will accrue and will be assessed sequentially. Each cohort will enroll participants with recurrent GBM. Cohort A will assess recurrent GBM participants who receive AMG 386 monotherapy at 30 g/kg every week. (Cohort A initially accrued at a dose of 15mg/kg, but this was increased to 30 mg/kg every week following an amendment). Cohort B will assess recurrent GBM participants who receive weekly AMG 386 plus bi‐weekly bevacizumab (10mg/kg). Cohort B will start with a Phase I component to determine the MTD of AMG 386 that is safe when used in combination with bevacizumab. AMG 386 is administered intravenously, and, when used in combination with intravenous bevacizumab, will be administered first. Patients will be required to come to the clinic weekly for study drug administration. For study purposes, a cycle of therapy will be 4 weeks. Treatment will continue until either evidence of progressive disease, unacceptable toxicity, non‐compliance with study follow‐up, or withdrawal of consent. The estimated rate of accrual is 60 participants per year. The estimated date of accrual completion is 1.5 years from study initiation. The estimated date of study completion will be approximately 12 months from enrollment of the last study participant.
