Brief summary
To obtain preliminary data in a randomized phase II study whether PPX/RT improves progression-free survival as compared to temozolomide/RT for patients with GBM without MGMT methylation.
Detailed description
To evaluate the toxicities of PPX/RT To evaluate neuro-cognitive functional assessments of patients with GBM receiving PPX/RT To obtain preliminary data in a randomized phase II study whether PPX/RT improves overall survival as compared to temozolomide /RT for patients with GBM without MGMT methylation to facilitate planning a phase III study.
Interventions
XRT: 60 Gy at 2 Gy/fraction x 30 fractions PPX: 50 mg/m2/week x 6 weeks during radiation Temozolomide maintenance: Beginning 4 weeks after completion of chemoradiation, temozolomide d1-5 of 28 day cycle for 12 cycle maximum.
XRT: 60 Gy at 2 Gy/fraction x 30 fractions Temozolomide, 75 mg/m2/day, 7 days per week, from the first to the last day of radiotherapy Temozolomide maintenance: Beginning 4 weeks after completion of chemoradiation, temozolomide d1-5 of 28 day cycle for 12 cycle maximum

Eligibility
Inclusion criteria
* Histologically proven diagnosis of glioblastoma or gliosarcoma (WHO grade IV) * GBM must have unmethylated MGMT as determined by central laboratory * Diagnosis of GBM must be made by biopsy or surgical excision, either partial or complete; as long as there is sufficient tissue to determine MGMT status * No prior chemotherapy or radiation for brain tumor * Must be able to tolerate brain MRIs. \*A diagnostic contrast-enhanced MRI must be performed postoperatively within 42 days prior to study registration. * KPS \>60. * Age \> 18 * Life expectancy of at least 3 months. * Absolute neutrophil count \> 1500/mm3, Platelets \> 100,000/mm, * Creatinine \< 2 x ULN * ALT or AST \< 3 x upper limit of normal (ULN) and total bilirubin \< 1.5x ULN. * Patients with a prior history of low grade glioma who did not receive prior radiation or chemotherapy with transformation to grade IV brain tumor are eligible. * Women must be non-lactating, and surgically sterile, post-menopausal or have a negative serum pregnancy test and agree to use adequate birth control. Males must agree to use adequate birth control. * Voluntary, signed informed consent.
Exclusion criteria
* Acute infection or other medical condition that would impair study treatment * No other active invasive malignancy unless disease free for at least 3 years. * Prior temozolomide or PPX. * Prior use of Gliadel wafers or any other intratumoral or intracavitary treatment are not permitted. * Prior radiotherapy to the head or neck (except for T1 glottic cancer), resulting in overlap of radiation fields. * No diffuse leptomeningeal disease, or gliomatosis cerebri. * Use of any other experimental chemotherapy drug within the 60 days prior to randomization and during the trial. (Use of a non-chemotherapy investigational agent must be approved by the Brown University Oncology Group)

|---|---|---|
| Progression Free Survival PPX/RT Versus TMZ/RT for Patients With GBM Without Methylation | Q 3 months on study then Q3 months in f/u for yr 1, q 4 months yr 2, q 6 months for approximately 4 ys. | MRI response evaluated by RANO criteria * Complete Response (CR): Circumstance when the enhancing tumor is no longer seen by neuroimaging, with the patient off all steroids or on adrenal maintenance only; CR will be coded only if confirmed by a second CT/MR scan performed a minimum of 4 weeks after the initial scan coding a response. * Partial Response (PR): Decrease of \> 50% in the product of two diameters. Patients should be receiving stable or decreasing doses of steroids. PR will be coded only if confirmed by a second CT/MR scan performed a minimum of 4 weeks after the initial scan. * Progression (P): A \> 25% increase in tumor area (two diameters) provided that the patient has not had his/her dose of steroids decreased since the last evaluation period. This will not need a confirmatory scan. A concomitant decrease in steroid dose will rule out a progression designation during the first 2 months after completion of XRT. |
