Gefitinib and Radiation Therapy in Treating Children With Newly Diagnosed Gliomas

2014년 5월 15일 업데이트: National Cancer Institute (NCI)

Phase I/II Trial of Gefitinib and Radiation in Pediatric Patients Newly Diagnosed With Brain Stem Tumors or Incompletely Resected Supratentorial Malignant Gliomas With Phase II Limited to Brain Stem Tumors

Biological therapies such as gefitinib may interfere with the growth of the tumor cells and may make the tumor cells more sensitive to radiation therapy. This phase I/II trial is studying how well giving gefitinib together with radiation therapy works in treating children with newly diagnosed glioma.

연구 개요

상세 설명

PRIMARY OBJECTIVES:

I. To define the safety of gefitinib administered in conjunction with irradiation in children with newly diagnosed non-disseminated diffuse intrinsic brainstem gliomas and newly diagnosed incompletely resected supratentorial malignant gliomas (STMG) not receiving enzyme inducing anticonvulsant drugs (EIACDs).

II. To define the safety of gefitinib in children with newly diagnosed, incompletely resected STMG receiving EIACDs.

III. To assess the safety and efficacy of gefitinib given with radiation therapy in children newly diagnosed with a brainstem glioma as measured by progression-free survival and to estimate the survival distribution.

SECONDARY OBJECTIVES:

I. To compare hemodynamic magnetic resonance (MR) parameters to metabolic fludeoxyglucose F 18 (FDG)-positron emission tomography (PET) scanning and correlate both with clinical response or progression in this population.

II. To characterize the expression of ErbB1 receptors in tissue from STMG patients using immunohistochemistry and western blot assays.

III. To characterize the pharmacokinetics of gefitinib in the above patient groups and determine the effects of EIACD on the pharmacokinetics.

IV. To explore the pharmacogenetic polymorphisms for gefitinib (e.g., CYP3A4/5 and BCRP) and relate them to gefitinib pharmacokinetics and pharmacodynamics (phenotype-genotype).

OUTLINE: This is a multicenter, dose-escalation study of gefitinib (Phase I closed to accrual effective 10/27/2003). Patients are stratified according to the following:

Stratum 1A: Intrinsic brain stem glioma; not receiving concurrent enzyme-inducing anticonvulsant drugs (EIACDs) Stratum 1B: Incompletely resected supratentorial malignant gliomas (STMG); not receiving concurrent EIACDs Stratum 2: Incompletely resected STMG; receiving concurrent EIACDs.

Phase I portion (patients in strata 1A, 1B, and 2) (phase I closed to accrual effective 10/27/2003): Patients receive oral gefitinib once daily. Treatment repeats every 4 weeks for 13 courses (1 year). Patients also receive standard brain irradiation once daily, 5 days a week, for 6 weeks beginning concurrently with initiation of the first course of gefitinib. Treatment continues in the absence of disease progression or unacceptable toxicity.

Cohorts of 3-6 patients receive escalating doses of gefitinib until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose preceding that at which 2 of 6 patients experience dose-limiting toxicity.

Phase II portion (patients in stratum 1A): Once the MTD or the recommended Phase-II dose is determined, additional patients who have newly diagnosed brain stem gliomas (BSG) are treated at the MTD or the recommended Phase-II dose.

Patients are followed for three months after the last protocol treatment for those enrolled strictly on the phase I component. Patients contributing to the phase II portion are followed until the earliest of date of death or three years after initiation of protocol therapy.

PROJECTED ACCRUAL: Considering the seven dose levels to be investigated in three strata, where each dose level can accrue up to six patients, a total of 126 patients (42 for each strata) may be accrued for this study within 2 years. (Phase I closed to accrual effective 10/27/2003). A total of 40 patients including the patients treated at the maximum tolerated dose or the recommended Phase-II dose during Phase I will be accrued for phase II of this study within 10 months.

Number of Participants in Phase I Stratum 1A With Dose-limiting Toxicities (DLT) Observed During the First 8 Weeks of Gefitinib Therapy
기간: Day 1 of gefitinib therapy to end of week 8
The dose limiting toxicity (DLT) analysis population consists of stratum 1A phase I participants who developed DLT during the maximum tolerated dose (MTD) estimation period (course 1 and 2) or who completed the MTD estimation period without DLTs. DLTs observed during courses 1 and 2 were used to estimate the MTD based on the tradional 3+3 design, where a dose is considered a safe dose only when 0 out of 3, or at most 1 out of 6 patients has DLTs. When two or more patients in a group of 2 to 6 patients had DLTs, then that dose level was considered to be too toxic.
Day 1 of gefitinib therapy to end of week 8

Median Survival in Newly Diagnosed Brain Stem Gliomas
기간: Assessed from the start of therapy until three years after initiation of gefitinib therapy

Mean Tumor to White Matter Ratio Measured at Baseline
기간: Baseline
This study attempts to characterize neuroimaging parameters from positron emission tomography. For each patient, the axial image through the tumor containing the maximum activity per pixel corresponding to the highest FluoroDeoxyGlucose (FDG) uptake was identified and a region of interest (ROI) was drawn based on the FDG definition of the tumor. The mean pixel values within the tumor ROI were normalized by those for normal white matter to provide ratios of tumor/gray matter. Each patient has a mean tumor to white matter ratio value and the median of these values across patients is reported.

Number of Patients With Epidermal Growth Factor Receptor (EGFR) Amplification
기간: Pre-treatment
Epidermal growth factor receptor (EFGR) is a protein found on the surface of cells to which epidermal growth factor (EGF) binds. When EGF attaches to EGFR, it activates the enzyme tyrosine kinase, triggering reactions that cause the cells to grow and multiply.
