  Purpose

Phase I/II trial to estimate the maximum tolerated dose of imatinib mesylate in newly diagnosed brain stem gliomas and recurrent high grade gliomas and to assess the effectiveness of imatinib mesylate in treating young patients who have newly diagnosed intrinsic brain stem glioma. Imatinib mesylate may interfere with the growth of tumor cells by blocking the enzymes necessary for their growth. Radiation therapy uses high-energy x-rays to damage tumor cells. Combining imatinib mesylate with radiation therapy may kill more tumor cells.

Primary Outcome Measures:
  • Number of Participants in Phase I Stratum I With Dose Limiting Toxicities (DLT) Observed During First 8 Weeks (Courses 1 and 2) of Imatinib Therapy [ Time Frame: Day 1 of Imatinib Mesylate Therapy to Week 8 ] [ Designated as safety issue: Yes ]
    The dose limiting toxicity (DLT) analysis population consists of phase I stratum I participants who developed DLT during the maximum tolerated dose (MTD) estimation period (course 1 and 2) or who completed the MTD estimation period (courses 1 and 2) without DLTs. DLTs observed during courses 1 and 2 were used to estimate the MTD. The estimated MTD based on the 23 participants who either had a DLT during course 1 or 2 or completed courses 1 and 2 without DLT is 265 mg/m2/day.

  • Number of Participants in Phase I Stratum II With Dose Limiting Toxicities (DLT) Observed During First 8 Weeks (Courses 1 and 2) of Imatinib Therapy [ Time Frame: Day 1 of Imatinib Mesylate Therapy to Week 8 ] [ Designated as safety issue: Yes ]
    The dose limiting toxicity (DLT) analysis population consisted of phase I stratum II participants who developed DLT during the maximum tolerated dose (MTD) estimation period (courses 1 and 2) or who completed the MTD estimation period (courses 1 and 2) without DLTs. DLTs observed during courses 1 and 2 were used to estimate the MTD. The estimated MTD based on the DLT analysis population of 20 in stratum IIA was 465 mg/m2/day. An MTD was not established in stratum IIB as no DLTs were observed at the higher dose levels of 620 and 800 mg/m2/day.

  • Median Progression-free Survival (PFS) [ Time Frame: Assessed pre-radiation, before the first dose of imatinib, and then every 8 weeks ] [ Designated as safety issue: No ]
    Progression-free survival is defined as the interval from initiation of treatment to the earliest of disease progression (tumor increase of 25% over baseline tumor measurement; appearance of new lesion(s); or progressive/worsening neurological status) or death for patients who failed, or to the last date of follow up for patients without failure.


Secondary Outcome Measures:
  • Change From Baseline in Volume FLAIR at Two Weeks After Completion of Radiation [ Time Frame: Baseline and two weeks post completion of radiation ] [ Designated as safety issue: No ]
    This study attempted to investigate in an exploratory manner the effect of radiation (RT) on changes in various neuroimaging variables in pediatric brainstem gliomas (stratum I). Neuroimaging changes may have some association with outcome (response, survival, etc.). Volume FLAIR is one parameter obtained from standard magnetic resonance imaging (MRI) studies of the brain. Volume FLAIR was obtained at baseline (pre-radiation) and within two (+/- one) weeks after completion of RT.

  • Peak Concentration (Cmax) [ Time Frame: Day 1 of Course 1 ] [ Designated as safety issue: No ]
    Peak concentration (cmax) is a pharmacokinetic measure defined as the highest concentration of a drug measured after the drug is administered. The cmax of imatinib mesylate on day 1 of course 1 is reported. Two milliliter (0.5 ml for children under the age of 5) blood samples were collected immediately prior to imatinib mesylate administration on Day 1 of Course 1 and at the following timepoints following drug administration: 0.5, 1, 1.5, 2, 4, 10 and 12 hours after the morning dose.

  • Median Overall Survival [ Time Frame: Assessed before radiation therapy, before the first dose of imatinib, then every 8 weeks. ] [ Designated as safety issue: No ]
    Overall Survival (OS) is defined as the interval from initiation of treatment to death or date of last contact for surviving patients.

  • Pre-treatment Basic Fibroblast Growth Factor Values From Urine [ Time Frame: Pre-treatment ] [ Designated as safety issue: No ]
    This study attempted to investigate in an exploratory manner the effect of biological markers on tumor growth. Basic fibroblast growth factor (bFGF) may play a role in tumor development by helping tumor vessels establish and grow. Urine was collected from participants before treatment to measure the baseline urine bFGF values.

  • Pre-treatment Basic Fibroblast Growth Factor Values From Plasma [ Time Frame: Pre-treatment ] [ Designated as safety issue: No ]
    This study attempted to investigate in an exploratory manner the effect of biological markers on tumor growth. Basic fibroblast growth factor (bFGF) may play a role in tumor development by helping tumor vessels establish and grow. Blood (plasma) was drawn from participants before treatment to measure the baseline plasma bFGF values.

  • Pre-treatment Vascular Endothelial Growth Factor From Urine [ Time Frame: Pre-treatment ] [ Designated as safety issue: No ]
    This study attempted to investigate in an exploratory manner the effect of biological markers on tumor growth. Vascular endothelial growth factor (VEGF) may play a role in tumor development by helping tumor vessels establish and grow. Urine was collected from participants before treatment to measure the baseline urine VEGF values.

  • Pre-treatment Vascular Endothelial Growth Factor Values From Plasma [ Time Frame: Pre-treatment ] [ Designated as safety issue: No ]
    This study attempted to investigate in an exploratory manner the effect of biological markers on tumor growth. Vascular endothelial growth factor (VEGF) may play a role in tumor development by helping tumor vessels establish and grow. Blood (plasma) was drawn from participants before treatment to measure the baseline plasma VEGF values.
