PPX and Concurrent Radiation for Newly Diagnosed Glioblastoma Without MGMT Methylation

Phase 2
Completed
Conditions
Glioblastoma Multiforme
Interventions
Drug: PPX (CT2103)
Registration Number
NCT01402063
Lead Sponsor
Brown University
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.

63
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 MethylationQ 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.
