Trial Outcomes & Findings for Gefitinib and Radiation Therapy in Treating Children With Newly Diagnosed Gliomas (NCT NCT00042991)

NCT ID: NCT00042991

Last Updated: 2014-05-28

Results Overview

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.

Participant Flow

Accrual to this study started with the first patient who enrolled on 07/01/2002 and ended with the last patient who enrolled on 05/31/2006. Nine institutions enrolled patients on the study.

There was no randomization to the three strata, which were distinct based on diagnosis and the use of enzyme inducing anti-convulsants (EIACD).

PRIMARY outcome

Timeframe: Day 1 of gefitinib therapy to end of week 8

Population: This cohort includes only the patients who were enrolled and treated on Gefitinib+Radiation during the Phase I component of the trial, where the safety of Gefitinib was assedded at Dose Levels 100 mg/m\^2, 250 mg/m\^2, and 375 mg/m\^2.

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.

PRIMARY outcome

Timeframe: Assessed pre-radiation, every 8 weeks for 13 courses of therapy, and then every 12 weeks

Population: Here, we only report the results for Phase-II trial as this objective was specifically for the Phase-II trial. This cohort includes seven patients who were treated during Phase-I at Dose 250 mg/m\^2 of Gefitinib.

Progression-free survival is defined as the interval from intiation of treatment to the earliest of disease progression (tumor increase of 25% over baseline tumor measurement; appearance of new lesion(s); or progressive/worsening neurlogical status) or death for patients who failed or to the last date of follow-up for patients without failure

SECONDARY outcome

Timeframe: Baseline and two weeks post completion of radiation

Population: Out of 43 patients, 35 patients had brain MRI before the treatment started and at the time of the completion of Radiation therapy. Therefore, this analysis is based on the volumetric data from these 35 patients.

This study attempted to investigate in an exploratory manner the effect of treatment on changes in various neuroimaging variables. In this particular objective, the study aimed to investigate how radiation+gefitinib affect the tumor volume. Tumor volume is measured using Fluid Attenuated Inversion Recovery (FLAIR) before and after the radiation therapy.

SECONDARY outcome

Timeframe: Baseline and two weeks post completion of radiation

Population: Out of 43 patients, for only 19 patients, enhacing tumor was greater than zero based on brain MRI scans before the treatment started and at the time of the completion of Radiation therapy. Therefore, this analysis is based on the enhancing volumetric data from these 19 patients.

This study attempted to investigate in an exploratory manner the effect of treatment on changes in various neuroimaging variables. Neuroimaging changes may have some association with outcome (response,survival, etc.). Volume enhancing is one parameter obtained from standard magnetic resonance imaging (MRI) studies of the brain.

SECONDARY outcome

Timeframe: Baseline

Population: Out of 43 patients, only 18 Patients had baseline PET scans. Therefore, this analysis is based on these 18 patients.

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 gray matter to provide ratios of tumor/gray matter. Each patient has a mean tumor to gray matter ratio value and the median of these values across patients is reported.

These are patients with brain stem glioma who were treated during the Phase-I trial of Radiation+Dose 375 mg/m\^2 of Gefitinib, where Gefitinib was administered orally once daily.
Dose 375 mg/m^2 of Gefitinib
n=8 Participants
This cohort includes all Phase-I patients treated at 375 mg/m\^2 of Gefitinib regardless of diagnosis; that is, this group includes both brain stem gliomas and supratentorial malignant gliomas. Eight of 12 patients had adequate PK samples for the PK evaluation.

Timeframe: Week 2 of course 1

Population: PK Data was combined at each dose level accross strata (Stratum 1A, Stratum 1B, and Stratum 2); at Dose 250 mg/m\^2 of Gefitinib accross strata, PK data from Phase-I patients was analysed earlier for the publication of the Phase-I trial. PK data for the Phase-II patients was analyzed separately for the Phase-II publication.

SECONDARY outcome

Timeframe: Pre-treatment

Population: Epidermal growth factor receptor is only possible with tumor sample, which is only potentially available from supratentorial malignant glioma patients treated on Stratum-1B and Stratum-2. Of 10 Stratum-1B and 3 Stratum-2 patients (n=13), tumor material was available from 11 patients (8 in Stratum-1A and 3 in Stratum-2).

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.
