This phase I trial is studying the side effects and best dose of RO4929097 when given together with temozolomide and radiation therapy in treating patients with newly diagnosed malignant glioma. Enzyme inhibitors, such as RO4929097, may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as temozolomide, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Radiation therapy uses high-energy x-rays to kill tumor cells. Giving RO4929097 together with temozolomide and radiation therapy may kill more tumor cells.

Primary Outcome Measures:
  • Maximum-tolerated dose defined as the highest dose studied for which the incidence of DLT is less than 33% using NCI Common Terminology Criteria for Adverse Events (CTCAE) version 4.0 [ Time Frame: 28 days ] [ Designated as safety issue: Yes ]
    The percentage of patients who experience toxicity at each dose level will be calculated, with a 95% confidence interval.

Secondary Outcome Measures:
  • Pharmacokinetics analysis [ Time Frame: Pre-dose, 30 minutes, 1, 2, 4, 6, and 8 hours ] [ Designated as safety issue: No ]
    Descriptive statistics (including number, mean and/or median, standard deviation, coefficient of variation, and range) for PK parameters will be tabulated by dose level.

  • Impact of RO4929097 on the components of the Notch pathway, on cancer stem cell population and on angiogenesis [ Time Frame: Up to 4 weeks ] [ Designated as safety issue: No ]
    Analyses will include comparison of results before and after exposure to RO4929097 (Wilcoxon rank sum test), as well as status of the Notch pathway and cancer stem cells in a control population of 20 untreated patients (Mann Whitney test).

  • Effects of RO4929097 and temozolomide on MRI parameters [ Time Frame: Up to 4 weeks ] [ Designated as safety issue: No ]
    Results will be summarized, and mean and median values at different time points will be tabulated. Changes in such parameters will be checked for statistical significance and correlated with the disease status.

  • Development of potential biomarkers for evaluation of gamma-secretase and Notch inhibitors activity [ Time Frame: Up to 4 weeks ] [ Designated as safety issue: No ]
    A Wilcoxon test will be used to determine p value of changes in mean values of YKL-40 and HES1, with a p value of less than 0.05 considered statistically significant.

Estimated Enrollment: 24
Study Start Date: May 2010
Estimated Primary Completion Date: July 2014 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Arm I

Pre-surgery treatment: Patients receive oral gamma-secretase inhibitor RO4929097 (RO4929097) once daily on days 1-7 of week 1 and day 1 of week 2.

Surgery: Patients undergo surgery 2-3 hours after administration of RO4929097 on day 1 of week 2.

Treatment concurrent with radiotherapy: Beginning 3-4 weeks after surgery, patients undergo conventional focal (intensity-modulated or 3-D conformal) radiotherapy 5 days a week for approximately 6 weeks. Patients also receive oral RO4929097 once daily for approximately 10 weeks beginning the day of radiotherapy and oral temozolomide once daily for approximately 6 weeks beginning the day before radiotherapy.

Adjuvant treatment following radiotherapy: Approximately 4 weeks after completion of radiotherapy, patients receive oral RO4929097 once daily on days 1-28 and oral temozolomide once daily on days 1-5. Treatment repeats every 28 days for 12 courses in the absence of disease progression or unacceptable toxicity.
