About

RATIONALE: Veliparib 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. Giving veliparib together with temozolomide may kill more tumor cells. PURPOSE: This randomized phase I/II trial is studying the side effects and best dose of giving veliparib together with temozolomide and to see how well it works in treating patients with recurrent glioblastoma.

Full description

OBJECTIVES: Primary To define the maximum-tolerated dose of the combination of temozolomide and veliparib in patients with recurrent glioblastoma previously or not treated with temozolomide. (Phase I*) To determine the efficacy of the combination of temozolomide and veliparib (using a 5-day vs 21-day schedule) as measured by the 6-month progression-free survival rate in patients with recurrent glioblastoma previously treated with temozolomide. (Phase II*) Secondary To characterize the safety profile of the combination of temozolomide and veliparib. (Phase I*) To determine the adverse event profile and tolerability of the combination of temozolomide and veliparib (using a 5-day vs 21-day schedule) in patients with recurrent glioblastoma. (Phase II*) To determine the efficacy of the combination of temozolomide and veliparib (using a 5-day vs 21-day schedule) as measured by objective response in patients with measurable disease. (Phase II*) To determine the overall survival of patients treated with the combination of temozolomide and veliparib (using a 5-day vs 21-day schedule). (Phase II*) Note: *Phase I was closed and phase II was opened on 3/6/12. OUTLINE: This is a multicenter, phase I* dose-escalation study followed by a phase II* randomized study. Patients enrolled in the phase II portion are stratified according to bevacizumab (BEV) status (bevacizumab-naive vs bevacizumab-failure), age (< 50 years vs ≥ 50 years), Karnofsky performance status (70-80% vs 90-100%), and recent resection (yes vs no/biopsy only). Phase I:* Patients receive oral temozolomide once daily and oral veliparib twice daily on days 1-21. Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity. Phase II:* Patients are randomized to 1 of 2 treatment arms. Arm I: Patients receive temozolomide and veliparib as in phase I. Arm II: Patients receive oral temozolomide once daily and oral veliparib twice daily on days 1-5. Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity. After completion of study treatment, patients are followed up every 12 weeks for 1 year, every 26 weeks for 2 years, and then annually thereafter. Note: *Phase I was closed and phase II was opened on 3/6/12. PROJECTED ACCRUAL: A total of 240 patients (28 for phase I* and 212 for phase II*) will be accrued for this study.

Inclusion and exclusion criteria

DISEASE CHARACTERISTICS:

Histologically confirmed diagnosis of 1 of the following:

  • Any intracranial high-grade glioma (phase I*)
  • Glioblastoma or gliosarcoma (phase II*)
  • Patients whose original histology was low-grade glioma are eligible provided they were subsequently diagnosed with glioblastoma or gliosarcoma

Unequivocal radiographic evidence for tumor progression by MRI within 14 days prior to registration and with a stable or decreasing dose of steroids at least 5 days prior to scanning OR recent resection (registration within 30 days of resection) as long as all of the following conditions are met:

  • Patients must have recovered from the effects of surgery
  • Residual disease following resection of recurrent glioblastoma is not mandated for eligibility into the study; to best assess the extent of residual disease post-operatively, a post-operative MRI scan should be performed within 28 days prior to registration and within 96 hours post surgery (although 24 hours would be optimum)
  • Prior radiation is required for the phase I* arm
  • Patients must have completed a course of radiation therapy and at least 2 consecutive adjuvant cycles of temozolomide (phase II*)
  • A stable or decreasing dose of steroids at least 5 days prior to scanning is not mandated for patients who had a recent resection

No evidence of acute (i.e., new and active) intratumoral hemorrhage on MRI

Patients with MRI demonstrating old hemorrhage or subacute blood after a neurosurgical procedure (biopsy or resection) are eligible Note: *Phase I was closed and phase II was opened on 3/6/12.
