About this study
Official title: 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.
Read the detailed description
PRIMARY OBJECTIVES:
- 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:
- 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.

What is being measured
The primary outcome is the main question the study is designed to answer.
Number of Participants in Phase I Stratum 1A With Dose-limiting Toxicities (DLT) Observed During the First 8 Weeks of Gefitinib Therapy
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.
Measured: Day 1 of gefitinib therapy to end of week 8
Median Progression-free Survival in Newly Diagnosed Brain Stem Gliomas
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
Measured: Assessed pre-radiation, every 8 weeks for 13 courses of therapy, and then every 12 weeks
Median Survival in Newly Diagnosed Brain Stem Gliomas
Overall survival is defined as the interval from initiation of treatment to death or date of last contact for surviving patients
Measured: Assessed from the start of therapy until three years after initiation of gefitinib therapy
Secondary outcomes (12)
Change in Tumor Volume Measured on Fluid Attenuated Inversion Recovery (FLAIR) Imaging at Before the Protocol Therapy Started and at Two Weeks After Completion of Radiation
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.
Measured: Baseline and two weeks post completion of radiation
Change From Baseline in Volume Enhancing at Two Weeks After Completion of Radiation
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.
Measured: Baseline and two weeks post completion of radiation
Change From Baseline in Diffusion Ratio at Two Weeks After Completion of Radiation
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.). Diffusion ratio is one parameter obtained from standard magnetic resonance imaging (MRI) studies of the brain.
Measured: Baseline and two weeks post completion of radiation
Change From Baseline in Perfusion Ratio at Two Weeks After Completion of Radiation
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.). Perfusion ratio is one parameter obtained from standard magnetic resonance imaging (MRI) studies of the brain.
Measured: Baseline and two weeks post completion of radiation
Mean Tumor to Gray Matter Ratio Measured at 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 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.
Measured: Baseline
Mean Tumor to White Matter Ratio Measured at 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.
Measured: Baseline
Peak Serum Concentration of Gefitinib (Cmax)
Measured: Week 2 of course 1
Elimination Half Life of Gefitinib (t1/2)
Measured: Week 2 of course 1
Clearance of Gefitinib (Cl)
Measured: Week 2 of course 1
Time of Maximum Clearance of Gefitinib (Tmax)
Measured: Week 2 of course 1
Gefitinib Area Under the Concentration Curve From 0-24 Hours (AUC)
Measured: Week 2 of course 1
Number of Patients With Epidermal Growth Factor Receptor (EGFR) Amplification
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.
Measured: Pre-treatment

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
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.
Detailed description
PRIMARY OBJECTIVES:
- 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:
- 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
Time frame: 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.
Median Progression-free Survival in Newly Diagnosed Brain Stem Gliomas
Time frame: Assessed pre-radiation, every 8 weeks for 13 courses of therapy, and then every 12 weeks
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
Median Survival in Newly Diagnosed Brain Stem Gliomas

Questions about this trial
What is this clinical trial studying?
A Phase 1/2 study testing gefitinib, radiation therapy and pharmacological study in people with Untreated Childhood Anaplastic Astrocytoma and Untreated Childhood Anaplastic Oligodendroglioma, run by National Cancer Institute (NCI) at 1 site in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 19 inclusion and 8 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 28 May 2014. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this combined phase mean?
Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Yes. Results are posted in the registry (first posted 11 Jul 2011). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Number of Participants in Phase I Stratum 1A With Dose-limiting Toxicities (DLT) Observed During the First 8 Weeks of Gefitinib Therapy (time frame: Day 1 of gefitinib therapy to end of week 8). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 28 May 2014.
