    Childhood Acute Lymphoblastic Leukemia Treatment (PDQ®): Treatment - Health Professional Information [NCI] - Postinduction Treatment for Specific ALL Subgroups


    Treatment options under clinical evaluation for T-cell ALL

    Treatment options under clinical evaluation for T-cell ALL include the following:

    1. COG-AALL0434 (NCT00408005) (Combination Chemotherapy in Treating Young Patients With Newly Diagnosed T-Cell ALL or T-cell Lymphoblastic Lymphoma):

      COG-AALL0434 is a phase III trial utilizing a modified augmented BFM regimen for patients aged 1 to 30 years with T-cell ALL. Patients are classified into one of three risk groups (low, intermediate, or high) based on NCI age/leukocyte criteria, CNS status at diagnosis, morphologic marrow response on days 15 and 29, and minimal residual disease (MRD) level at day 29. The objectives of the trial include the following:

      • To determine the safety and efficacy of adding nelarabine to the modified augmented BFM regimen in high- and intermediate-risk patients.
      • To determine the relative safety and efficacy of high-dose (5 g/m2) versus Capizzi escalating lower-dose methotrexate without rescue plus PEG-asparaginase during interim maintenance.
      • To test the efficacy of treating NCI standard-risk T-cell ALL patients, without CNS disease, who are rapid responders (about 15% of patients) without cranial radiation.
    2. DFCI-11-001 (NCT01574274) (SC-PEG Asparaginase versus Oncaspar in Pediatric ALL and Lymphoblastic Lymphoma):

      Patients with T-cell ALL are eligible to enroll on a DFCI ALL Consortium protocol that is comparing the pharmacokinetics and toxicity of two forms of intravenous PEG-L-asparaginase (pegaspargase [Oncaspar] and calaspargase pegol [SC-PEG]). Patients will be randomly assigned to receive a single dose of one of these preparations during multiagent induction, and then either pegaspargase every 2 weeks (15 doses total) or calaspargase pegol every 3 weeks (10 doses total) during the 30-week consolidation phase.

      This protocol is also testing whether antibiotic prophylaxis (with fluoroquinolones) reduces rates of bacteremia and other serious bacterial infections during the remission induction phase. All T-cell patients are treated on the high-risk arm of this trial, regardless of other presenting characteristics.

    Current Clinical Trials

    Check for U.S. clinical trials from NCI's list of cancer clinical trials that are now accepting patients with T-cell childhood acute lymphoblastic leukemia. The list of clinical trials can be further narrowed by location, drug, intervention, and other criteria.
