Ifosfamide, Carboplatin, Etoposide, and SGN-30 in Treating Young Patients With Recurrent Anaplastic Large Cell Lymphoma

This phase I/II trial is studying the side effects and best dose of SGN-30 when given together with ifosfamide, carboplatin, and etoposide and to see how well they work in treating young patients with recurrent anaplastic large cell lymphoma. Drugs used in chemotherapy, such as ifosfamide, carboplatin, and etoposide, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Monoclonal antibodies, such as SGN-30, can block cancer growth in different ways. Some block the ability of cancer cells to grow and spread. Others find cancer cells and help kill them or carry cancer-killing substances to them.

PRIMARY OBJECTIVES:

I. Define and describe the toxicities of monoclonal antibody SGN-30 alone (window) and in combination with ifosfamide, carboplatin, and etoposide (ICE) in pediatric patients with CD30-positive recurrent anaplastic large cell lymphoma.

II. Define, preliminarily, the antitumor activity of monoclonal antibody SGN-30 alone (window) and in combination with ICE in these patients.

SECONDARY OBJECTIVES:

I. Characterize the pharmacokinetics of monoclonal antibody SGN-30 in these patients.

II. Characterize the soluble CD30 concentrations at time of relapse in these patients.

III. Characterize the development of human antichimeric antibodies in these patients.

IV. Measure minimal residual disease in these patients.

OUTLINE: This is a multicenter, pilot, phase I, dose-finding study of monoclonal antibody SGN-30 followed by a phase II study.

Patients receive monoclonal antibody SGN-30 IV alone on day 1 in weeks 1-8. Beginning in week 5, patients receive ICE chemotherapy comprising ifosfamide IV over 2 hours on days 1-3, carboplatin IV over 1 hour on day 1, and etoposide IV over 1 hour on days 1-3. Treatment with ICE repeats every 3 weeks for 6 courses\*\* in the absence of unacceptable toxicity. Patients also receive intrathecal therapy comprising methotrexate, cytarabine, and hydrocortisone once on day 29 (week 5).

NOTE: \*\*Patients planning to undergo bone marrow transplantation (BMT) receive 2 courses of ICE only and then undergo BMT off study.

Cohorts of 3-6 patients receive a pre-determined dose of monoclonal antibody SGN-30 with possible dose de-escalation to 1 dose level below in the event of ≥ 2 of 6 patients experience dose-limiting toxicity (DLT). The dose at which ≤ 1 of 6 patients experience DLT will be used in a phase II study.

After completion of study treatment, patients are followed periodically for 5 years.
