简要总结

The primary purpose of the study is to evaluate the efficacy (overall response) and safety of temozolomide in Step 1 at the dose and regimen approved in the US and the EU countries (28 day cycles of temozolomide at 150 to 200 mg/m2 once daily for 5 consecutive days with a 23 day rest period) in patients with anaplastic astrocytoma at first relapse.

  • unequivocal evidence of tumor recurrence or aggravation by MRI scan after treatment for initial onset; the lesions must be measurable;
  • anaplastic astrocytoma diagnosed histologically by the last pathological diagnostic tests (including initial diagnosis) prior to initial administration of temozolomide;
  • tissue samples available for Central Pathologic Reviewer;
  • pathologic diagnosis report by the study-conducting medical institution must be available for the sponsor.
  • MRI-related criteria:
  • MRI scan performed within 14 days before initial temozolomide administration;
  • assessable tumor site confirmed by MRI;
  • dosage of steroidal agents not increased within 7 days before MRI prior to initial temozolomide administration, except for postoperative subjects for first relapse;

  • Karnofsky performance status >=
  • Adequate clinically laboratory values obtained within 14 days before initial temozolomide administration.
  • Criteria regarding treatment of initial onset:
  • tumor biopsy, regardless of tumor resection at initial diagnosis;
  • prior radiation therapy;
  • prior chemotherapy with up to one nitrosourea-containing regimen.
  • Tumor may or may not have been surgically resected at first relapse, but residual measurable disease is required.
  • For subjects who had surgical resection of tumor at first relapse:
  • MRI scan must have been performed within 72 hours after surgery.
  • the dose of steroidal agents must be reduced before temozolomide administration.
  • Life expectancy >=12 weeks.
  • Written informed consent obtained.

  • Subjects who received interstitial radiotherapy or stereotactic radiosurgery.
  • Subjects who completed radiotherapy within 12 weeks before initial temozolomide administration.
  • Surgery at first relapse (including biopsy) within 1 week before initial temozolomide administration.
  • Subjects not recovered from acute toxicity due to previous therapy.
  • High-risk subjects with complication of diseases other than malignant tumor, or who require systemic administration of antibiotics for infection.
  • Previous or concurrent malignancies at other sites.
  • Pregnant or nursing women.
  • Women of childbearing potential not using an effective method of contraception.
  • Subjects previously treated with temozolomide.
  • Participation in an ongoing clinical study, or in other clinical studies within 6 months before initial temozolomide administration.

研究组 & 干预措施

Single arm

Experimental

The study consists of two steps:

  • Step 1, the therapeutic study phase, comprising six cycles of treatment with temozolomide, and
  • Step 2, the long-term treatment phase, where subjects with at least disease stabilization at the end of Step 1 may continue temozolomide treatment until unacceptable toxicity or disease progression occur, up to a maximum of 2 years from the start of treatment in Cycle 1.

干预措施: Temozolomide (Drug)
