A Phase II/III Randomized Trial of Veliparib or Placebo in Combination With Adjuvant Temozolomide in Newly Diagnosed Glioblastoma With MGMT Promoter Hypermethylation
Description
Brief Summary
This randomized phase II/III trial studies how well temozolomide and veliparib work compared
to temozolomide alone in treating patients with newly diagnosed glioblastoma multiforme.
Drugs used in chemotherapy, such as temozolomide, work in different ways to stop the growth
of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping
them from spreading. Veliparib may stop the growth of tumor cells by blocking some of the
enzymes needed for cell growth. It is not yet known whether temozolomide is more effective
with or without veliparib in treating glioblastoma multiforme.
Detailed Description
PRIMARY OBJECTIVE:
I. Test whether the experimental combination of ABT-888 (veliparib) combined with TMZ
(temozolomide), compared to the control of placebo combined with TMZ, significantly extends
overall survival in newly diagnosed glioblastoma multiforme (GBM) patients with tumor MGMT
promoter hypermethylation.
SECONDARY OBJECTIVES:
I. Test whether the experimental treatment significantly extends progression-free survival.
II. Test whether the experimental treatment improves objective tumor response. III. Test
whether the experimental treatment is associated with significantly greater rates of grade 3
or higher adverse events.
CORRELATIVE SCIENCE OBJECTIVES:
I. Evaluate the utility of dynamic susceptibility contrast (DSC) and diffusion weighted
imaging (DWI) magnetic resonance imaging (MRI) techniques in defining time to progression in
the setting of a large multi-institutional clinical trial.
II. Test the concordance between site-determined MGMT methylation status and central
laboratory determination of MGMT status in cases with local testing.
III. Evaluate whether genetic or epigenetic alterations in deoxyribonucleic acid (DNA) repair
or replication genes are associated with overall survival, progression-free survival, and
objective tumor response.
IV. Test whether polymorphisms in MGMT, PARP1, or other DNA repair proteins, are associated
with overall survival, progression-free survival, objective tumor response, or rates of grade
3 or higher adverse events.
OUTLINE: Patients are randomized to 1 of 2 treatment arms.
ARM I: Patients receive temozolomide orally (PO) once daily (QD) on days 1-5 and veliparib PO
twice daily (BID) on days 1-7. Treatment repeats every 28 days for 6 cycles in the absence of
disease progression (confirmed progression) or unacceptable toxicity.
ARM II: Patients receive temozolomide as in Arm I and placebo PO BID on days 1-7. Treatment
repeats every 28 days for 6 cycles in the absence of disease progression (confirmed
progression) or unacceptable toxicity.
After completion of study treatment, patients are followed up every 3 months for 3 years,
every 6 months for 2 years.
Phase
Phase 2/3 - for trials that are a combination of phases 2 and 3.Inclusion and Exclusion Criteria
- Inclusion Criteria:

- Sufficient tissue available for central pathology review and MGMT methylation status evaluation
- Patients who have had a local MGMT testing that is unmethylated are not allowed to participate
- Tumor MGMT promoter hypermethylation determined by central testing at MD Anderson
- Confirmation by central pathology review of WHO grade IV glioblastoma or gliosarcoma
- Absolute neutrophil count (ANC) >= 1500 cells/mm^3 (within 14 days prior to study registration)
- Platelets >= 100,000 cells/mm^3 (within 14 days prior to study registration)
- Creatinine =< 1.5 x upper limit of normal (ULN) (within 14 days prior to study registration)
- Bilirubin =< 1.5 x ULN (within 14 days prior to study registration; unless patient has Gilbert's disease)
- Alanine aminotransferase (ALT) =< 3 x ULN (within 14 days prior to study registration)
- Aspartate aminotransferase (AST) =< 3 x ULN (within 14 days prior to study registration)
- Eastern Cooperative Oncology Group (ECOG) performance status =< 2
- Measurable disease or non-measurable disease; extent of resection: patients with complete resection, partial resection, or biopsy are eligible
- Progression: patients deemed to have progressive disease based on clinical deterioration after chemoradiation or radiographic progression outside of the radiation field are not eligible; patients deemed to have pseudoprogression are eligible
- Prior treatment:
- Must have completed standard radiotherapy and concomitant TMZ therapy as defined and determined by the study oncologist
- Besides concomitant TMZ with radiation, no other therapy (neo-adjuvant or adjuvant) can be given prior to study registration, including chemotherapy (also including Gliadel/carmustine [BCNU] wafers), biologics, immunotherapy, radiation therapy; the only exception is the Optune device (NovoTTF-100A), which may be started any time after end of radiation therapy up through the initiation of Cycle 1; intent to use Optune must be declared at registration for stratification
- No prior allogeneic bone marrow transplant or double umbilical cord blood transplantation
- Not pregnant and not nursing; females of childbearing potential must have negative urine or serum pregnancy test within 7 days of registration but before start of treatment; a female of childbearing potential is a sexually mature female who:
- Has not undergone a hysterectomy or bilateral oophorectomy; or
- Has not been naturally postmenopausal for at least 12 consecutive months (i.e., has had menses at any time in the preceding 12 consecutive months)
- Concomitant medications: patients receiving anticoagulation should be on stable dose 2 weeks prior to registration
- Comorbid conditions: patients are unable to participate due to the following:
- Generalized or partial seizure disorder that is uncontrolled at the time of registration; the definition of controlled generalized seizures is patients must be on a stable dose of anti-seizure medication and without generalized seizures for at least 10 days prior to registration; the definition of controlled partial seizures is patients must be on a stable dose of anti-seizure medication for at least 10 days prior to registration; patients with occasional breakthrough partial seizures are allowed at treating physician's discretion
- Grade 3 or 4 thromboembolic disease within 6 months (mo) of registration

- >= 10.0 g/dL hemoglobin (Hb) with no blood transfusion in the past 28 days
- No Patients with treatment-related acute myeloid leukemia (AML) (t-AML)/myelodysplastic syndrome (MDS) or with features suggestive of AML/MDS
