RATIONALE: 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.

PURPOSE: 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.

Detailed Description:



  • To establish the maximum-tolerated dose and the recommended phase II dose of gamma-secretase inhibitor RO4929097 (RO4929097) in combination with temozolomide and radiotherapy in patients with newly diagnosed glioblastoma multiforme, anaplastic astrocytoma, gliosarcoma, or other malignant gliomas.


  • To evaluate the pharmacokinetics of RO4929097 and temozolomide in these patients.
  • To evaluate brain and tumor penetration by this regimen, including radiotherapy, in these patients.


  • To evaluate pharmacodynamic effects of RO4929097 in the resected specimens from these patients in comparison with specimens obtained from untreated patients.
  • To evaluate the effects of RO4929097 on the cancer stem cells of these patients.
  • To evaluate the effects of RO4929097 on angiogenesis (microvascular density and expression of tumor vascular markers, including vascular E-cadherin, CD146, CD31, VEGF ligands and receptors, and pericyte markers).
  • To evaluate the combined effects of this regimen in explants established from tumor specimens of these patients and controls.
  • To evaluate the effects of RO4929097 on MRI parameters, including DCE-MRI perfusion, diffusion-weighted imaging, and volumetric analysis.
  • To evaluate, preliminarily, the efficacy of this regimen at 6 months in these patients.
  • To determine, preliminarily, the median progression-free survival and overall survival of patients treated with this regimen.
  • To evaluate potential biomarkers of RO4929097and Notch inhibition activity in plasma and hair follicle samples.

OUTLINE: This is a multicenter, dose-escalation study of gamma-secretase inhibitor RO4929097.

  • Pre-surgery treatment (arm A [surgical patients] only): 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 6 courses in the absence of disease progression or unacceptable toxicity. After completion of 6 adjuvant courses, RO4929097is discontinued and temozolomide is continued for an additional 6 courses.

Blood and tumor tissue samples are analyzed for pharmacokinetics on days 0-2 of week 1 and day 1 of week 5. Other biomarker studies are conducted on blood and hair follicle samples.

After completion of study therapy, patients are followed up for 4 weeks and periodically thereafter.
