NCCTG Status Report for Study N May 2010

Transcription

1 Phase I/Randomized Phase II Trial of Either Dasatinib or Placebo Combined with Standard Chemo-Radiotherapy for Newly Diagnosed Glioblastoma Multiforme (GBM) Purpose of - Phase I Study: 1) To establish a maximum tolerable dose of dasatinib combined with radiation and temozolomide in this patient population. - Phase II 1) To determine the efficacy of dasatinib in combination with RT and concomitant and adjuvant TMZ in patients with newly diagnosed glioblastoma multiforme, and compare it with the standard of care approach in the treatment of these patients consisting of RT and TMZ, followed by adjuvant TMZ (Stupp regimen). - Translational (Phase II only) 1) To determine the relationship between tumor biomarkers and clinical outcome of patients treated with the dasatinib/rt/tmz combination. 2) s part of ongoing research for NCCTG studies, we are banking paraffin-embedded tissue blocks/slides and blood products for furture studies. 3) Evaluate potential mechanisms of therapy resistance in recurrent tumor samples obtained at the time of surgery for recurrent disease. - QOL (Phase II only) 1) ssess the impact of the addition of dasatinib to RT/TMZ on quality of life (QOL) using both FCT-Br (50 items) and EORTC QLQ-C15-PL plus BN20 (35 items). 2) To compare the results of the two most commonly used QOL tools, FCT- Br (50 items) and EORTC QLQ-C15-PL plus BN20 (35 items) and validate the use of EORTC QLQ-C15-PL plus BN20 (35 items) in newly diagnosed GBM patients.

Study 1 will be a phase I cohort of 3 dose-escalation trial of dasatinib in combination with radiation and concomitant TMZ. Study 2 will be a randomized phase II trial with two 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 RT/TMZ followed by TMZ alone), or the experimental arm (continuous dialy dasatinib prior, during and after standard RT/TMZ followed by TMZ). ccrual: This study was activated on 06/05/2009. s of 03/23/2010, four patients have been enrolled to the phase I portion (three at dose level 0 and one at dose level 0-) of this study. Patient Characteristics: vailable baseline information is summarized in the Baseline Characteristics Table below. The 4 patients are 2 (50%) male and 2 (50%) female ranging in age from 49 to 58 (median age=54.5). No one is classified as a minority. vailable Information: s of 03/23/2010, all 4 patients are alive with 3 still on-study. No patients have been declared ineligible. No patients have been replaced. Three patients have response data available. dverse Events: With adverse event data available for 3 patients (see dverse Events Table below), four grade 4 events (1 leukopenia, 1 lymphopenia, 1 thrombocytopenia, 1 neutrophil count decreased) have been seen in 2 patients. No grade 5 events have been seen. One DLT has been seen (grade 4 neutrophil count decreased, leukopenia, and thrombocytopenia) at dose level 0. Study Status: s of 03/23/2010, this study is open to accrue an additional 2 patients at dose level 0-. ccrual Table: N Page 3 of 5
