简要总结
RATIONALE: Dasatinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Monoclonal antibodies, such as bevacizumab, can block tumor growth in different ways. Some block the ability of tumor cells to grow and spread. Others find tumor cells and help kill them or carry tumor-killing substances to them. Bevacizumab may also block the growth of the tumor by blocking blood flow to the tumor. It is not yet known whether bevacizumab together with dasatinib are more effective than a placebo in treating patients with recurrent or progressive high-grade glioma or glioblastoma multiforme.
PURPOSE: This randomized phase I/II trial (Phase I completed) is studying the side effects and best dose of dasatinib when given together with bevacizumab and to see how well it works compared to placebo in treating patients with recurrent or progressive high-grade glioma or glioblastoma multiforme.
详细描述
OUTLINE: This is a multicenter, phase I, dose-escalation study (Phase I completed) of dasatinib followed by a phase II randomized study. Patients are grouped according to study (1 vs 2). Patients in the phase II portion are stratified according to age (> 70 years of age vs ≤ 70 years of age), and ECOG performance status (0 vs 1 or 2).
Phase I: Patients receive bevacizumab IV over 30-90 minutes on day 1. Patients also receive oral dasatinib once or twice daily on days 1-14 until the maximum-tolerated dose (MTD) is determined. Courses repeat every 14 days in the absence of disease progression or unacceptable toxicity. (Phase I completed) Please see the Arms section for the Phase II treatment regimens.
OBJECTIVES:
PRIMARY OBJECTIVES:
- Determine the maximum tolerated dose (MTD) of dasatinib in combination with bevacizumab in high grade glioma patients. (Phase I)
- To assess the safety and adverse events of the dasatinib in combination with bevacizumab in this patient population. (Phase I)
- To estimate the efficacy of the bevacizumab combination with dasatinib in recurrent glioblastoma multiforme as measured by progression free survival at six months and compare it with the efficacy of bevacizumab alone. (Phase II)

Note: Many antiepileptic drugs induce hepatic enzymes. Because dasatinib is metabolized by hepatic enzymes, patients taking antiepileptic medications that induce hepatic enzymes (EIACs) are ineligible for this trial. To be eligible for this trial, patients taking EIACs must be switched to non-EIACs ≥ 7 days prior to registration.

结局指标
主要结局
Number of Participants With Dose Limiting Toxicities to Determine Maximum Tolerated Dose (MTD) of Dasatinib in Combination With Bevacizumab (Phase I)
时间窗: 14 days
The Maximum Tolerated Dose (MTD) will be based on the assessment of dose-limiting toxicities (DLT) during the first 4 weeks of treatment only (i.e., following the first 2 treatment cycles), and will be defined as the dose at which fewer than one-third of patients experience a DLT to study treatment. The MTD is the dose level at which 0/6 or 1/6 patients experience DLT with the next higher dose having at least 2 out of 3 or 2 out of 6 patients encountering DLT.\> Three patients will be treated at each dose level, and can be enrolled simultaneously. If one DLT is encountered, an additional 3 patients will be added to that dose level. If at any point two DLTs are encountered within a given dose level, then the MTD has been exceeded and if only three patients have been treated at the next lower dose three more patients are treated at the next lower dose. The number of patients who developed DLTs are reported here by dose level, with the MTD reported in the statistical analysis section.
Progression-free Survival at 6 Months (PFS6) (Phase II)
时间窗: 6 months
The primary endpoint is the proportion of patients alive and progression-free 6 months after study treatment initiation (PFS6). All eligible consented patients that received treatment will be considered evaluable. Those who die will be considered to have had disease progression unless documented evidence clearly indicates no progression has occurred. PFS6 is defined as the time from start of study therapy to the date of first observation of disease progression or death due to any cause. Progression is defined using Response Evaluation Criteria In Solid Tumors Criteria (RECIST v1.0), as a 20% increase in the sum of the longest diameter of target lesions, or a measurable increase in a non-target lesion, or the appearance of new lesions. The PFS6 will be estimated as the number of evaluable patients progression free and still alive at 6 months divided by the total number of evaluable patients. The confidence interval will be calculated according to the Clopper-Pearson Method.
