Total Therapy for Infants With Acute Lymphoblastic Leukemia (ALL) I


Brief description of study

The purpose of this study is to test the good and bad effects of the study drugs bortezomib and vorinostat when they are given in combination with chemotherapy commonly used to treat acute lymphoblastic leukemia (ALL) in infants. For example, adding these drugs could decrease the number of leukemia cells, but it could also cause additional side effects. Bortezomib and vorinostat have been approved by the US Food and Drug Administration (FDA) to treat other cancers in adults, but they have not been approved for treating children with leukemia. With this research, we plan to meet the following goals:

PRIMARY OBJECTIVE:

  • Determine the tolerability of incorporating bortezomib and vorinostat into an ALL chemotherapy backbone for newly diagnosed infants with ALL.

SECONDARY OBJECTIVES:

  • Estimate the event-free survival and overall survival of infants with ALL who are treated with bortezomib and vorinostat in combination with an ALL chemotherapy backbone.
  • Measure minimal residual disease (MRD) positivity using both flow cytometry and PCR.
  • Compare end of induction, end of consolidation, and end of reinduction MRD levels to Interfant99 (ClinicalTrials.gov registration ID number NCT00015873) participant outcomes.

Detailed Study Description

Treatment will consist of 4 main phases: Remission Induction, Consolidation, Reinduction, and Maintenance. High risk patients will receive a reintensification phase prior to transplant in first remission.

REMISSION INDUCTION: Chemotherapy will be given in an attempt to induce the participant's leukemia into remission. Drugs given are intrathecal triple drug treatment with methotrexate, hydrocortisone and Ara-C (ITMHA); dexamethasone; vorinostat; bortezomib; PEG-asparaginase; mitoxantrone; cyclophosphamide; cytarabine; and 6-mercaptopurine.

CONSOLIDATION PHASE: After the participant's blood counts have recovered from Remission Induction, he/she will move to the consolidation phase. This therapy is given to kill any remaining leukemia cells. Drugs given are ITMHA, high-dose methotrexate, and 6-mercaptopurine.

RE-INDUCTION: This phase aims to improve the participant's overall response to therapy by again seeking to bring his/her leukemia into remission. Drugs given are ITMHA, mitoxantrone, peg-asparaginase, dexamethasone, bortezomib, and vorinostat.

RE-INTENSIFICATION: If the participant's maximum residual disease (MRD) is not negative after consolidation, he/she will receive intensification therapy, then go on to stem cell transplant (SCT) (SCT not part of this study).

MAINTENANCE PHASE: Participants with negative MRD after consolidation will skip the re-intensification phase and proceed to receive maintenance therapy to keep the leukemia from returning. Drugs given are ITMHA, dexamethasone, vincristine, 6-mercaptopurine and methotrexate. Each cycle of these drugs lasts 28 days and will be repeated up to 20 times as long as there are no serious side effects.
