Continuous Temozolomide in Patients With Advanced or Metastatic Soft Tissue Sarcoma or Metastatic Breast Cancer

Because repeated dosing of temozolomide correlates with an improved response, which may be due to progressive depletion of the enzyme AT, our hope is that a daily oral schedule will be the most active schedule of this agent. In phase I studies doses below 85 mg/m2/day continuously have been well-tolerated. We plan to begin dosing at 75 mg/m2/day for 6 weeks out of an 8 week cycle and to escalate to 85 and 100 mg/m2/day in patients who have no grade 3/4 toxicity. The purpose of this study is to determine whether treatment with temozolomide can effect the survival of patients with advanced breast cancer or soft tissue sarcoma. To do this we will assess the response rate, time to progression, and survival in patients with advanced breast cancer or soft tissue sarcoma who are treated with temozolomide.
