Brief Summary:
The purpose of this non-randomized, open-label, multicenter, Phase II, 2-stage design, RESCUE study is to test the hypothesis that continuous 28-day oral dosing (28/28) with dose-intense temozolomide (50 mg/m^2) for up to 12 months may overcome resistance and be effective in the management of adult patients with malignant glioma who have failed following at least 2 cycles (2 months) of conventional 5-day (5/28) cycles of high-dose temozolomide (150-200 mg/m^2).

Inclusion Criteria:

  • Adult patients, greater than 18 years old.

  • Must have completed at least 2 cycles (2 months) of conventional 5/28 temozolomide, with radiological evidence of progression.
  • GBM treated with concurrent chemoradiation with temozolomide according to the EORTC/NCIC (European Organization for Research & Treatment of Cancer/National Cancer Institute of Canada) protocol.
  • Evidence of progression confirmed radiologically (CT [computed tomography] or MRI [magnetic resonance imaging]).
  • Patients must be enrolled within 2 weeks of last radiological confirmation of progression, except for patients undergoing surgical resection.
  • Patients undergoing surgical resection for recurrent disease must be enrolled within 2 weeks of the post-surgical scan.
  • Patients with no residual disease after surgery are allowed.
  • Steroids dose should have been stabilized during the last 2 weeks prior to enrollment.
  • Use of medically approved contraception in fertile males and females.
  • Women of childbearing potential must have a negative urine or serum pregnancy test (urinary excretion or serum level of bHCG [beta human chorionic gonadotropin]) within 24 hours of inclusion in the study.
  • Eastern Cooperative Oncology Group (ECOG) score of 0 or 1.
  • Signed informed consent form.

Exclusion Criteria:

  • GBM progression during the first 2 months of adjuvant temozolomide (5/28).
  • AA progression during the first 2 months of standard temozolomide therapy (5/28).
  • Chemotherapy for the malignant glioma other than temozolomide.
  • More than one prior course of chemotherapy with temozolomide.
  • Patient evolving from anaplastic glioma to GBM following primary therapy.
  • Patient older than 70 years or who received no conventional chemoradiation regimen.
  • Patient who received radiotherapy for recurrent disease.
  • Patient with metastatic disease.
  • Known human immunodeficiency virus (HIV) infection.
  • History of non-compliance to other therapies.
  • Inadequate hematological, renal and hepatic function according to all of the following laboratory values (to be performed within 14 days, inclusive, prior to study inclusion):
  • Absolute neutrophil count <=1.5 ×10^9/L;
  • Platelets <=100 ×10^9/L;
  • Hemoglobin <90 g/L;
  • Serum creatinine >=1.5 times upper limit of laboratory normal (ULN);
  • Total serum bilirubin >=1.5 times ULN;
  • ASAT (AST [aspartate aminotransferase]) or ALAT (ALT [alanine aminotransferase) >2.0 times ULN;
  • Alkaline phosphatase of >2.5 times ULN.
  • Known chronic hepatitis B or hepatitis C infection.
  • Any other serious medical condition, according to the medical judgment of the physician prior to inclusion in the study.
  • Any medical condition that could interfere with oral medication intake (e.g., frequent vomiting, partial bowel obstruction).
  • Other malignancies during the previous 5 years with the exception of surgically cured carcinoma in-situ of the cervix and basal cell carcinoma or non-melanoma skin cancer.
  • Any psychological, familial, sociological, or geographical condition potentially hampering compliance with the study protocol and follow-up schedule as discussed with the patient before inclusion in the study.
