Study Summary

This phase I trial is studying the side effects and best dose of vorinostat when given together with temozolomide in treating patients with malignant gliomas. Drugs used in chemotherapy, such as vorinostat and temozolomide, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Vorinostat may also stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Vorinostat may help temozolomide work better by making tumor cells more sensitive to the drug. Giving vorinostat together with temozolomide may kill more tumor cells.

Primary Outcome

For both parts of the study, treatment administration will be described for all cycles. Doses administered, dose modifications/delays, and duration of therapy will be evaluated. Safety variables summarized by descriptive statistics. Adverse events that occur will be reported for each dose level and described in terms of incidence and severity. Laboratory data will be presented by dose level at each observation time. Values outside of normal limits will be identified and their frequency calculate
