Clinical Trial Summary

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.

Description:

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.

Eligibility

Inclusion Criteria:

Patients must have either:

• Stage IV, microscopically-confirmed carcinoma of the breast with:

• Relapse or progression while receiving, or within 12 months of having received, an anthracycline-containing (doxorubicin or mitoxantrone) or taxane-containing (paclitaxel or docetaxel) regimen as either adjuvant treatment or therapy for advanced breast cancer, or

• Treatment to a maximum dose of anthracycline (e.g., greater than 450 mg/m2 of doxorubicin), or

• A dose-limiting toxicity from a taxane, or

• An ECOG performance status of 2.

• OR —

• Unresectable or metastatic, microscopically-confirmed soft tissue sarcoma, that is not amenable to treatment with Adriamycin or Ifosfamide due to:

• Poor cardiac reserve, or

• Poor performance status (ECOG performance status = 2) or

• Having failed treatment with Adriamycin or reached dose-limiting toxicity from chemotherapy.

Patients must have histologic slides and/or blocks must be available for review.

Patients must have measurable (bidimensionally) or evaluable disease.

Patients must be 18 years old or older.

Patients must have Karnofsky Performance Status greater than 70% (ECOG less than 2) at screen and on the first day of treatment.

Patients must have a life expectancy more than 16 weeks.

Patients must be informed consent must be obtained prior to enrollment.

Patients must be more than 2 weeks from prior surgery; more than 3 weeks from radiation therapy to the pelvis, spine or long bones; more than 3 weeks from prior chemotherapy (more than 6 weeks for mitomycin C or nitrosureas), or more than 2 weeks from prior hormonal therapy.

Exclusion Criteria:

Granulocytes less than 1,500/mm3.

Platelet count less than 100,000/mm3.

Hemoglobin less than 10 gm/dl.

Creatinine greater than 2.0 mg/dl.

Total bilirubin greater than ULN (institutional upper limit of normal).

Pregnancy or lactation; failure to employ adequate contraception.

Uncontrolled CNS disease.

Greater than 30% marrow previously irradiated.
