Phase 2

Trial Purpose and Description

Trial Purpose

This phase II trial is studying the side effects of giving bortezomib together with combination chemotherapy and to see how well it works in treating young patients with relapsed acute lymphoblastic leukemia or lymphoblastic lymphoma. Bortezomib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Giving bortezomib together with combination chemotherapy may kill more cancer cells.


Trial Description


PRIMARY OBJECTIVES:

I. To estimate the toxicity, second complete response (CR2) rate at the end of Block 1
therapy, and 4-month event-free survival (EFS) for pediatric and young adult patients with
relapsed acute lymphoblastic leukemia (ALL) treated with bortezomib in combination with
intensive re-Induction chemotherapy.

II. To evaluate bortezomib pharmacokinetics (PK) in patients receiving the combination
regimen.

SECONDARY OBJECTIVES:

I. To assess minimal residual disease (MRD) in bone marrow following completion of each
therapy block.

II. To assess the feasibility of measuring leukemia initiating cells (LIC) in patient
samples before and after chemotherapy.

III. To discover biologic pathways associated with response and drug resistance using gene
and protein expression profiles at baseline and following initial exposure to chemotherapy.

IV. To determine if bortezomib inhibits lymphoblast NF-kappa-B activity in leukemia
patients.

OUTLINE:

REINDUCTION BLOCK 1: Patients receive cytarabine intrathecally (IT) on day 1; vincristine
sulfate IV on days 1, 8, 15, and 22; doxorubicin hydrochloride IV over 15 minutes on day 1;
oral prednisone twice daily on days 1-29; bortezomib IV on days 1, 4, 8, and 11; and
pegaspargase intramuscularly (IM) on days 2, 8, 15, and 22. Patients with central nervous
system (CNS)-negative disease (CNS1 or CNS2) also receive methotrexate IT on days 15 and 29;
patients with CNS-positive disease (CNS3) receive triple intrathecal therapy (TIT)
comprising methotrexate, hydrocortisone, and cytarabine IT on days 8, 15, 22, and 29. After
completion of reinduction block 1, patients with ALL and M2 or M3 bone marrow proceed
directly to reinduction block 2. Patients with ALL and M1 bone marrow or lymphoblastic
lymphoma proceed to reinduction block 2 after blood counts recover. Patients with persistent
cerebral spinal fluid (CSF) blasts after 6 doses of TIT or patients with progressive
lymphoblastic lymphoma are removed from the study.

REINDUCTION BLOCK 2: Patients receive etoposide phosphate IV over 1-2 hours on days 1-5;
cyclophosphamide IV over 1 hour on days 1-5; bortezomib IV on days 1, 4, and 8; filgrastim
(G-CSF) subcutaneously (SC) or IV daily beginning on day 6 and continuing until blood counts
recover*; high-dose methotrexate IV on day 22; and leucovorin calcium orally or IV every 6
hours on days 23 and 24. Patients with CNS-negative disease also receive methotrexate IT on
days 1 and 22; patients with CNS-positive disease receive TIT on days 1 and 22. After
completion of reinduction block 2, patients proceed to reinduction block 3 immediately or
when blood counts recover. Patients with disease progression are removed from the study.

NOTE: *Patients do not receive G-CSF on day 8.

REINDUCTION BLOCK 3: Patients receive cytarabine IV over 3 hours twice daily on days 1, 2,
8, and 9; L-asparaginase IM on days 2 and 9; and G-CSF SC or IV daily beginning on day 10
and continuing until blood counts recover.

After completion of study treatment, patients are followed every 6 months for 3 years and
then annually for 2 years.
