Trial Information

Phase I Study of ET-743 in Pediatric Refractory Solid Tumors

OBJECTIVES: I. Determine the maximum tolerated dose and dose-limiting toxicity of
ecteinascidin 743 in pediatric patients with refractory solid tumors. II. Determine the
pharmacokinetics of this drug in these patients. III. Determine the antitumor activity of
this drug in this patient population.

OUTLINE: This is a dose escalation, multicenter study. Patients are stratified according to
pretreatment (pretreated vs less heavily pretreated). Patients receive ecteinascidin 743 IV
over 3 hours on day 1. Treatment continues every 3 weeks in the absence of disease
progression or unacceptable toxicity. Cohorts of 3-6 patients receive escalating doses of
ecteinascidin 743 until the maximum tolerated dose (MTD) is determined. The MTD is defined
as the dose preceding that at which 2 of 3 or 2 of 6 patients experience dose-limiting

PROJECTED ACCRUAL: A total of 3-20 patients will be accrued for this study within 2 years.

Inclusion Criteria

DISEASE CHARACTERISTICS: Histologically confirmed malignant solid tumor at original
diagnosis Refractory to standard treatment or no curative therapy available No CNS tumor

prior peripheral blood stem cell transplantation and no evidence of graft-vs-host disease
For less heavily pretreated stratum: No prior peripheral blood stem cell transplantation
Chemotherapy: At least 4 weeks since prior myelosuppressive chemotherapy (6 weeks for
nitrosoureas) and recovered No prior ecteinascidin 743 For less heavily pretreated
stratum: No more than 2 prior chemotherapy regimens Endocrine therapy: Not specified
Radiotherapy: At least 2 weeks since prior local palliative radiotherapy (small port) At
least 6 weeks since prior substantial bone marrow radiotherapy At least 6 months since
prior craniospinal radiotherapy or radiotherapy to 50% or greater of pelvis For less
heavily pretreated stratum: No prior craniospinal irradiation of 18Gy or greater No prior
irradiation to greater than 50% of pelvis Recovered from toxic effects of prior
radiotherapy Surgery: Not specified Other: No concurrent foods or medication that
interferes with P-450 metabolism Anticonvulsants allowed
