Trial Description

Summary

This phase II trial is studying the side effects and best dose of bortezomib and to see how well it works when given together with combination chemotherapy in treating younger patients with recurrent, refractory, or secondary acute myeloid leukemia (AML). Bortezomib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as idarubicin, cytarabine, and etoposide, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Giving more than one drug (combination chemotherapy) together with bortezomib may kill more cancer cells

Further Study Information

PRIMARY OBJECTIVES:

I. To determine the toxicities and tolerability of bortezomib in combination with standard-relapse AML therapy (idarubicin/cytarabine or etoposide/high-dose cytarabine) in pediatric and young adult patients with relapsed or primary-refractory or secondary AML.

II. To estimate the complete response rate to the Arm A and Arm B regimens.

SECONDARY OBJECTIVES:

I. To determine whether bortezomib inhibits proteasome activity, NF-kB activity and induces apoptosis pathway proteins in leukemia myeloblasts. II. To determine the feasibility of measuring AML stem cells in relapsed and recovering bone marrow.

OUTLINE: This is a multicenter, dose-escalation study of bortezomib. Patients are stratified according to anthracycline*-equivalent cumulative exposure (≤ 400 mg/m² vs > 400 mg/m²). Patients are assigned to 1 of 2 groups.

GROUP I (efficacy phase, patients with ≤ 400 mg/m² anthracycline-equivalent cumulative exposure - Closed as of 08/01/10): Patients receive idarubicin IV over 15 minutes on days 1-3, low-dose cytarabine IV continuously over days 1-7, and bortezomib IV on days 1, 4, and 8.

GROUP II (dose-finding phase (closed as of 10/10) and efficacy phase, patients with > 400 mg/m² anthracycline*-equivalent cumulative exposure): Patients receive etoposide IV over 1 hour on days 1-5, high-dose cytarabine IV over 1 hour twice daily on days 1-5, and bortezomib IV on days 1, 4, and 8.

NOTE: * Anthracycline restriction no longer required for group 2 as of 10/02/10.

All patients receive intrathecal cytarabine prior to courses 1 and 2. In both arms, treatment repeats every 28 days for up to 2 courses in the absence of disease progression or unacceptable toxicity.

After completion of study therapy, patients are followed periodically for at least 5 years.
