I. Determine the dose-limiting toxic effects and recommended phase II dose of oblimersen when combined with cyclophosphamide, doxorubicin, and dexrazoxane in pediatric patients with relapsed or refractory solid tumors.
II. Determine the pharmacokinetic behavior of this regimen in these patients. III. Determine, preliminarily, the antitumor activity of oblimersen in these patients.
IV. Assess the biologic activity of oblimersen in mononuclear cells and tumor tissues, in terms of bcl-2 and related protein expression, in these patients.
OUTLINE: This is a 2-part, multicenter, dose-escalation study.
Part A: Patients receive oblimersen IV continuously on days 1-7. Patients also receive dexrazoxane IV followed by doxorubicin IV over 15 minutes followed by cyclophosphamide IV over 1 hour on days 5 and 6. Filgrastim (G-CSF) is administered subcutaneously once daily beginning on day 8 and continuing until blood counts recover. Treatment repeats every 21 days for up to 18 courses (1 year) in the absence of disease progression or unacceptable toxicity. Patients with stable or responding disease whose shortening fraction falls below 28% by echocardiogram or whose total life-time cumulative anthracycline dose exceeds 750 mg/m^2 may receive additional courses of oblimersen and cyclophosphamide without doxorubicin and dexrazoxane.
Cohorts of 3-6 patients receive escalating doses of oblimersen until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose preceding that at which at least 2 of 3 or 2 of 6 patients experience dose-limiting toxicity.
Part B: Patients receive oblimersen at the MTD determined in part A and escalating doses of dexrazoxane, doxorubicin, and cyclophosphamide on the same treatment schedule as in part A.
Cohorts of 3-6 patients receive escalating doses of dexrazoxane, doxorubicin, and cyclophosphamide until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose preceding that at which at least 2 of 3 or 2 of 6 patients experience dose-limiting toxicity.
Patients are followed for survival.
PROJECTED ACCRUAL: A total of 12-15 patients will be accrued for this study within 1-2 years.
