Dasatinib or Placebo, Radiation Therapy, and Temozolomide in Treating Patients With Newly Diagnosed Glioblastoma Multiforme

Study Overview
=================
Brief Summary
-----------------
Dasatinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. It may also make tumor cells more sensitive to radiation therapy. Radiation therapy uses high-energy x-rays to kill tumor cells. Drugs used in chemotherapy, such as temozolomide, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. This randomized phase I/II trial is studying the best dose of dasatinib and to see how well it works compared with a placebo when given together with radiation therapy and temozolomide in treating patients with newly diagnosed glioblastoma multiforme.

Detailed Description
-----------------
This trial includes a phase I dose-escalation study and a double-blind randomized phase II trial for patients with newly diagnosed glioblastoma multiforme (GBM). Phase I will be a cohort of 3 dose-escalation trial of dasatinib in combination with radiation and concomitant temozolomide. Patients receive concomitant chemotherapy and radiation therapy for cycle one. Patients receive adjuvant chemotherapy 28-42 days post cycle one treatment. Patients receive only dasatinib post cycle 8 treatment until progressive disease, unacceptable adverse events or refusal. Phase II will be a randomized trial with two treatment arms. Patients will be randomized at the time of registration at a ratio of 1:2 respectively to either standard therapy arm (continuous daily placebo prior, during and after standard radiotherapy/temozolomide followed by temozolomide. For more information please see the Arms section. The primary objectives are listed below. Primary Objectives: To establish a maximum tolerated dose of dasatinib combined with radiation and temozolomide in this patient population (Phase I) To determine the efficacy of dasatinib in combination with radiotherapy and concomitant and adjuvant temozolomide in patients with newly diagnosed glioblastoma, and compare it with the standard of care approach in the treatment of these patients consisting of radiotherapy and temozolomide, followed by adjuvant temozolomide (Phase II) Patients are followed for 5 years post treatment. The study permanently closed to accrual on January 31, 2014.

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Overall Survival | Overall survival (OS) is the primary endpoint and is defined as the time from study registration to time of death due to any cause. All patients who meet the eligibility criteria, have signed a consent form, and have received at least one dose of the regimens will be considered evaluable. Patients who are lost to follow-up will be censored at the date of their last follow-up. Patients still alive at the time of analysis will be censored. Only Phase II was evaluated for survival | Up to 5 years post treatment | 
| The Number of Dose Limiting Toxicities(DLT) in Order to Determine Maximum Tolerable Dose(MTD) of Dasatinib Combined With Radiation and Temozolomide in This Patient Population. | Doselimiting toxicity will be defined as: Adverse event at least possibly related to the study medication. All by CTCAE v3.0 criteria: Greater than or equal to grade 3: diarrhea or skin rash or desquamation or (other) clinically relevant non-hematological adverse event or non-hematologic adverse event at least possibly due to drug therapy. Or greater than or equal to grade 4: neutropenia or leukopenia or thrombocytopenia or radiation dermatitis or hematologic adverse event OR failure to administer greater than 75% of dasatinib TMZ or interruption of RT for more than 5 days due to adverse events.OR severe acute central nervous system deterioration attributable to TMZ, RT and or dasatinib which cannot be controlled with corticosteroid administration. The MTD for this study will be defined as the highest safely tolerated dose level where at most 1 out of 6 patients experience DLT with the next higher dose having at least 2 patients out of a maximum of 6 patients experience DLT. | Every cycle from first dose to end of rest period prior cycle 3 | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Progression-free Survival | Progression-free survival (PFS) is defined as the time from study registration to the date of first observation of disease progression or death due to any cause (whichever comes first). If a patient has not progressed or died, progression-free survival is censored at the time of last follow-up. Only Phase II patients were evaluated for Progression-free survival | Up to 5 years post treatment | 
| Objective Response | Objective response to treatment will be determined by a combination of the results of neurological exam and the MRI and/or CT measurement of the tumor at each evaluation as is used for all NCCTG neuro-oncology trials. The proportion of patients in each response category will be summarized. Only phase II patients were evaluated for response. | Up to 5 years post treatment |
