Brief Summary
RATIONALE: Enzastaurin may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth and by blocking blood flow to the tumor. PURPOSE: This phase I trial is studying the side effects and best dose of enzastaurin in treating young patients with refractory primary brain tumors.

Outcome Measures
Primary Outcomes (2)
Maximum tolerated dose
The maximum tolerated dose or recommended phase II dose will be based on the dose-limiting toxicities observed during the first 28 days of therapy in those participants receiving enzastaurin on a once per day dosing schedule.
First 28 days of therapy
Number of participants treated with the maximum tolerated dose or phase II recommended dose on a twice daily dosage schedule with dose-limiting toxicities
First 28 days of therapy
Secondary Outcomes (6)
Pharmacokinetics
Three days prior to course 1 and day 28 of course 1
Toxicity
From day 1 of therapy until 30 days after the last dose of the drug
Tumor response
Pre-treatment, day 15 of course 1, and at the end of courses 3, 5, 8, 11, and 13.
Change in MR perfusion parameters obtained within 15 ± 2 days after initiation of enzastaurin hydrochloride therapy as compared to baseline
Baseline and day 15 of course 1
Change from baseline in the inhibition of Akt cell signaling at day 14 and day 28
Pre-treatment and at days 14 and 28 of course 1
- +1 more secondary outcomes
Interventions
Participants receive 200, 260, 340, or 440 mg/m2/day of enzastaurin orally once daily for 28 days (one course) during the dose escalation phase of the study. To study the toxicity profile of the MTD or phase II recommended dose established during the dose escalation phase, participants receive twice daily doses of enzastaurin orally at the phase II recommended dose for 28 days (one course). In the absence of unacceptable toxicity or disease progression, treatment may continue for 13 courses (approximately one year).
Eligibility Criteria
You may qualify if:

- +1 more criteria
You may not qualify if:
- Pregnant or lactating

- Must not have received myelosuppressive chemotherapy within 3 weeks of entry onto this study (6 weeks for prior nitrosourea)
- At least 7 days since the completion of therapy with a hematopoietic growth agent (i.e., filgrastim \[G-CSF\], sargramostim \[GM-CSF\], or erythropoietin)
- At least 14 days since long-acting formulations
- Therapeutic use of myeloid growth factors in patients with serious neutropenic conditions, such as sepsis, may be considered at the investigator's discretion
- At least 7 days since the completion of therapy with a biologic agent
- At least 2 weeks since prior local palliative radiotherapy (small port)
- At least 6 months must have elapsed after prior total body irradiation (TBI) or craniospinal radiotherapy
