Conditions
Brief summary
There will be 2 phases in this study. Patients will either be enrolled to the first phase or to the second phase, depending upon when they enroll into the study. The first phase of this study is done to evaluate the safety of enzastaurin in patients. This is done by gradually increasing the dose of the drug in small groups of patients and watching closely for side effects. In the second phase of the study, the dose determined to be safe will be used with temozolomide during and following radiation therapy to see if the combination can help patients with brain tumors live longer.
Interventions

Eligibility
Inclusion criteria
* Patients must have a histologically confirmed diagnosis of intracranial glioblastoma multiforme (GBM) or gliosarcoma (GS). * Biopsy or resection must have been performed no more than 5 weeks prior to treatment. * An MRI or CT scan must be obtained within 14 days prior to treatment. * Patients must not have received prior drug therapy for brain tumors. * Patients must have adequate organ function demonstrated by lab tests within 14 days prior to treatment.
Exclusion criteria
* Patients will be excluded if unable to swallow tablets. * Patients will be excluded if unable to discontinue use of enzyme inducing antiepileptic drugs or have been off of these agents less than 2 weeks prior to treatment (i.e. phenytoin (Dilantin®), carbamazepine, etc.). * Patients will be excluded if have active infection. * Patients will be excluded if have a significant medical illness that, in the investigator's opinion, cannot be adequately controlled with appropriate therapy or would compromise the patient's ability to tolerate this therapy. * Patients will be excluded if they have concurrent therapy with an anticoagulant. If the patient requires anticoagulant therapy after starting treatment, the patient may remain on study but should be monitored carefully.

Primary
| Measure | Time frame | Description |
|---|---|---|
| Phase 1- Determination of the Maximum Tolerated Dose (MTD) of Enzastaurin | Until MTD can be determined (up to 12 cycles, 28 days per cycle) | Phase 1- dose escalation of enzastaurin in 2 cohorts up to 6 participants each in order to assess MTD.

If no significant toxicity after the first cycle, participants received subsequent cycles. If no more than 1 of the 6 patients treated at 250 mg of enzastaurin experienced a DLT, up to 6 more patients could be entered at escalated dose cohort of enzastaurin (500 mg). |

Phase 1 and 2: Association Between Biomarkers and Clinical Outcome
Phosphorylated-S6 (pS6) ribosomal protein is a biomarker that's being investigated as a potential marker for clinical outcome using 2211 or 2215 antibody to pS6. Reported here are the hazard ratios and 95% confidence intervals (CIs) for participants for whom an pS6 immunohistochemistry (IHC) score was available. The IHC assays were scored using a 0 to +3 scoring system (no positive staining was scored 0; at least 25% immunoreactivity of cells was scored +1; 26% to 75% was scored +2; and 76% or greater was scored +3). Hazard ratio (HR) \> 1 indicates worse outcome for that IHC score.
Time frame: Baseline, Cycle 2, end of study (up to 12 cycles, 28 days per cycle)
Population: Combined Phases 1 and 2 populations for whom IHC scores were obtained. HR \> 1 indicates poorer overall survival for that IHC score.

Phase 1 - Response Rate With Macdonald Criteria
Response categories: complete response (CR): disappearance of all enhancing tumor on consecutive magnetic resonance imaging (MRI) scans at least 1 month apart, off steroids, and neurologically stable or improved. Partial response (PR): 50% reduction in size of enhancing tumor on consecutive MRI scans at least 1 month apart, steroids stable or reduced, and neurologically stable or improved. Progressive disease (PD): \>25% increase in size of enhancing tumor or any new tumor on MRI scans, or neurologically worse, and steroids stable or increased. Stable disease (SD): all other situations.
Time frame: Baseline, following radiation, every other cycle (up to 12 cycles, 28 days per cycle)
Population: Efficacy analysis in phase I was not conducted. Instead, participants who took 250mg in phase I were pooled with phase II participants and are presented in other outcome measures (2 and 8, respectively) in this record. Thus there were 0 participants for this measure.
Phase 2 - Number of Participants With Adverse Events (AEs)
Summaries of serious AEs (SAEs) and all other non-serious AEs are located in the Reported Adverse Event Module.
Time frame: Every cycle (28 days per cycle)
Population: All Phase 2 participants who received at least one dose of study drug.
