Summary
Brief summary (as posted)
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.

- measure
- 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
- timeFrame
- Day 1 of Imatinib Mesylate Therapy to Week 8
- description
- 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.
