Total Therapy XVII for Newly Diagnosed Patients With Acute Lymphoblastic Leukemia and Lymphoma
The overarching objective of this study is to use novel precision medicine strategies based on inherited and acquired leukemia-specific genomic features and targeted treatment approaches to improve the cure rate and quality of life of children with acute lymphoblastic leukemia (ALL) and acute lymphoblastic lymphoma (LLy).
Primary Therapeutic Objectives:
- To improve the event-free survival of provisional standard- or high-risk patients with genetically or immunologically targetable lesions or minimal residual disease (MRD) ≥ 5% at Day 15 or Day 22 or ≥1% at the end of Remission Induction, by the addition of molecular and immunotherapeutic approaches including tyrosine kinase inhibitors or chimeric antigen receptor (CAR) T cell / blinatumomab for refractory B-acute lymphoblastic leukemia (B-ALL) or B-lymphoblastic lymphoma (B-LLy), and the proteasome inhibitor bortezomib for those lacking targetable lesions.
- To improve overall treatment outcome of T acute lymphoblastic leukemia (T-ALL) and T-lymphoblastic lymphoma (T-LLy) by optimizing pegaspargase and cyclophosphamide treatment and by the addition of new agents in patients with targetable genomic abnormalities (e.g., activated tyrosine kinases or JAK/STAT mutations) or by the addition of bortezomib for those who have a poor early response to treatment but no targetable lesions, and by administering nelarabine to T-ALL and T-LLy patients with leukemia/lymphoma cells in cerebrospinal fluid at diagnosis or MRD ≥0.01% at the end of induction.
- To determine in a randomized study design whether the incidence and/or severity of acute vincristine-induced peripheral neuropathy can be reduced by decreasing the dosage of vincristine in patients with the high-risk CEP72 TT genotype or by shortening the duration of vincristine therapy in standard/high-risk patients with the CEP72 CC or CT genotype.
Secondary Therapeutic Objectives:
- To estimate the event-free survival and overall survival of children with ALL and to assess the non-inferiority of TOTXVII compared to the historical control given by TOTXVI.
- To estimate the event-free survival and overall survival of children with LLy when ALL diagnostic and treatment approaches are used.
- To evaluate the efficacy of blinatumomab in B-ALL patients with end of induction MRD ≥0.01% to <1% and those (regardless of MRD level or TOTXVII risk category) with the genetic subtypes of BCR-ABL1, ABL-class fusion, JAK-STAT activating mutation, hypodiploid, iAMP21, ETV6-RUNX1-like, MEF2D, TCF3-HLF, or BCL2/MYC or with Down syndrome, by comparing event-free survival to historical control from TOTXVI.
- To determine the tolerability of combination therapy with ruxolitinib and Early Intensification therapy in patients with activation of JAK-STAT signaling that can be inhibited by ruxolitinib and Day 15 or Day 22 MRD ≥5%, Day 42 MRD ≥1%, or LLy patients without complete response at the End of Induction and all patients with early T cell precursor leukemia.
Biological Objectives:
- To use data from clinical genomic sequencing of diagnosis, germline/remission and MRD samples to guide therapy, including incorporation of targeted agents and institution of genetic counseling and cancer surveillance.
- To evaluate and implement deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) sequencing-based methods to monitor levels of MRD in bone marrow, blood, and cerebrospinal fluid.
- To assess clonal diversity and evolution of pre-leukemic and leukemic populations using DNA variant detection and single-cell genomic analyses in a non-clinical, research setting.
- To identify germline or somatic genomic variants associated with drug resistance of ALL cells to conventional and newer targeted anti-leukemic agents in a non-clinical, research setting.
- To compare drug sensitivity of ALL cells from diagnosis to relapse in vitro and in vivo and determine if acquired resistance to specific agents is related to specific somatic genome variants that are not detected or found in only a minor clone at initial diagnosis.
Supportive Care Objectives
- To conduct serial neurocognitive monitoring of patients to investigate the neurocognitive trajectory, mechanisms, and risk factors.
- To evaluate the impact of low-magnitude high frequency mechanical stimulation on bone mineral density and markers of bone turnover.
There are several Exploratory Objectives.

Detailed Description
Participants will be classified into one of three categories (low-, standard-, or high-risk) based on the presenting age, leukocyte count/lymphoma staging, presence or absence of CNS-3 status or testicular disease, immunophenotype, molecular genetics, DNA index, and early response to therapy.
Treatment will consist of three main phases: Remission Induction, Consolidation, and Continuation. Early Intensification therapy will be given prior to Consolidation to patients with provisional standard-risk or high-risk ALL/LLy or any provisional low-risk patients with Day 15 MRD ≥1% as well as provisional low-risk LLy patients who do not obtain complete response at the end of Induction. Patients with mixed phenotype acute leukemia (MPAL) are treated by using the same treatment stratification used in ALL although analysis is performed separately from ALL or LLy cohorts.
Brief outline of treatment plan:
Patients will be assigned to treatment based on risk group: Low-Risk, Standard-Risk and High-Risk and cell type (T or B cell).
Remission Induction initially consists of prednisone (28 days), vincristine (4 weekly doses), daunorubicin (1 to 3 weekly doses), and pegaspargase 1 dose for all patients and 2 doses for those with Day 15 MRD 1% or higher. The second part (given over 2 weeks and overlapping with the last week of the first part of induction) consists of cyclophosphamide, cytarabine, and mercaptopurine combinations. Dasatinib will be added for patients with Ph+ and Ph-like ABL-class fusions and bortezomib will be given to patients with no targetable lesions and Day 15 or Day 22 minimal residual disease (MRD) ≥ 5% on Days 29 and 32.
Early Intensification will be given prior to Consolidation to patients with provisional standard-risk or high-risk ALL/LLy or any provisional low-risk patients with Day 15 MRD ≥1% as well as provisional low-risk LLy patients who do not obtain complete response at the end of Induction. For patients with Ph-like ALL that is targetable with JAK inhibitor and Day 15 or Day 22 MRD level ≥5% or end of Remission Induction ≥1% as well as all patients with early T cell precursor (ETP) ALL and T/M MPAL, ruxolitinib will be used. This includes, but is not limited to CRLF2, JAK2, and EPOR rearrangements and sequence/structural changes in JAK1/2, TYK2, IL7R, and SH2B3. Ruxolitinib will be added in LLy patients with activation of JAK-STAT signaling that can be inhibited by ruxolitinib whose responses do not qualify complete response at the end of Remission Induction. Dasatinib will continue for patients with ABL-class fusions. Bortezomib will be added for patients with no targetable lesions and Day 15 or Day 22 MRD ≥ 5% or LLy patients without complete response at the End of Induction.
Consolidation Treatment will consist of high dose methotrexate (HDMTX) (every other week for 4 doses); daily mercaptopurine and IT chemotherapy on the same dates of HDMTX. Dasatinib will continue for patients with ABL-class fusions. Ruxolitinib will continue for patients with activation of JAK-STAT signaling that can be inhibited by ruxolitinib and Day 15 or Day 22 MRD ≥5% or Day 42 MRD ≥1% (or for LLy patients who do not qualify complete response at the end of Remission Induction) and all cases with ETP ALL and T/M MPAL.
Immunotherapy: CAR T-cell therapy will be considered for High-risk B-ALL and B-LLy patients. Blinatumomab will be given to patients with Standard-risk B-ALL and B-LLy with residual disease at the end of induction and High-risk B-ALL and B-LLy patients who are not able to receive CAR T-cell therapy. Blinatumomab is also given to patients with the following genetic subtypes (BCR-ABL1, ABL-class fusion, JAK-STAT activating mutation, hypodiploid, iAMP21, ETV6-RUNX1-like, MEF2D, TCF3/HLF, or BCL2/MYC) or with Down syndrome, regardless of MRD level and/or Total 17 risk category.
Reintensification therapy will be offered to certain High-risk patients with persistent MRD after Immunotherapy (B-ALL and B-LLy) or Early Intensification (T-ALL and T-LLy), or those who cannot receive Immunotherapy.
Continuation Treatment will consist of 120 weeks of risk-directed therapy. Dasatinib will continue in patients with ABL-class fusion. Ruxolitinib will continue in patients with activation of JAK-STAT signaling that can be inhibited by ruxolitinib and Day 15 or Day 22 MRD ≥5% or Day 42 MRD ≥1% (or for LLy patients who do not qualify complete response at the end of Remission Induction) and all cases with ETP ALL. T-ALL and T-LLy patients with leukemia/lymphoma cells in cerebrospinal fluid at diagnosis or MRD ≥0.01% at the end of Induction will receive nelarabine. ALL/LLy Patients with the CEP72 rs904627T/T genotype (16% of patients) will be randomized (unblinded design except those who evaluate neuropathies) to receive either 1.5 mg/m2 or 1 mg/m2 of vincristine after Continuation Week 1. Patients in low- risk will complete vincristine in Week 49 and those in standard/high-risk will complete in Week 101. Standard/high-risk patients with either a CEP72 rs904627 C/T or C/C genotype (84% of patients) will be randomized to receive vincristine and dexamethasone pulses through Week 49 of Continuation Treatment or through Week 101 of Continuation Treatment. Low-risk patients will complete vincristine in Week 49.
Intrathecal therapy is given throughout the treatment. The number of intrathecal therapy is based on the risk factors of central nervous system relapse.

Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
|---|---|---|
|
Event-free survival of ALL patients (EFS)
Time Frame: At 3.5 years after enrollment of the last participant
|
5-year EFS: Kaplan-Meier estimates of EFS curve of ALL patients will be computed and compared historically with those of the St. Jude Children's Research Hospital's (SJCRH) TOTXVI study (NCT00549848).
All eligible patients entered on the current TOT17 study will be included in these comparisons.
Comparisons by log-rank tests will be made both un-stratified and stratified by risk groups.
|
At 3.5 years after enrollment of the last participant
|
|
Proportion of patients with CEP72TT genotype who develop two or more episodes of Grade 2 or higher neuropathy during Continuation
Time Frame: At 6 months after the last randomized patient completes Continuation Treatment (Week 120).
|
This will be a single-blind, stratified block randomized experiment.
Although the investigators who evaluate neuropathy and neuropathic pain and the patients are blinded for treatment assignment, treating clinicians and pharmacy staff are not.
Patients will be randomized at a 1:1 ratio into two treatment groups: 1.5 mg/m^2 vs. 1 mg/m^2 vincristine (VCR) dose.
Randomization will be stratified by two factors known to significantly affect neuropathy during the Continuation phase, namely, Grade 2 or higher neuropathy prior to Continuation (none, 1 episode, 2 or more episodes) and race (black, others).
The proportion of patients who develop two or more episodes of Grade 2 or higher neuropathy during Continuation Treatment will be compared between the two VCR dose groups, using a Z-test for two sample proportions.
|
At 6 months after the last randomized patient completes Continuation Treatment (Week 120).
|
|
Cumulative incidence of Grade 2 or higher neuropathy in patients with CEP72 CC or CT genotype
Time Frame: After the last randomized patient is followed for 1 year after Week 101 of Continuation therapy
|
This will be a single blind stratified block randomized experiment.
The investigators who evaluate neuropathy and neuropathic pain and the patients are blinded for treatment assignment.
Treating clinicians and pharmacy staff will not be blinded.
Standard/high-risk patients will be randomized at a 1:1 ratio into two treatment groups at Week 49 of Continuation therapy: to vincristine + dexamethasone (VCR+DEX) pulses or to 6-mercaptopurine + methotrexate (6MP+MTX).
The primary analysis will compare the cumulative incidence of the first episode of Grade 2 or higher neuropathy or neuropathic pain (the end point) by stratified Gray's test.
Adverse events other than the endpoint rendering a patient drop out after Continuation Week 49 are regarded as competing events.

|
Log hazard ratio of the association of low level of MRD and treatment outcome
Time Frame: 3.5 years after enrollment of the last patient
|
The investigators will analyze the association of next-generation sequencing-determined MRD level (as a continuous variable) with the risk of relapses in bone marrow and possibly other sites (bone marrow or combined relapses).
Fine-Gray regression model will be applied to estimate the hazard ratio of relapse as a function of the increase in MRD level.
|
3.5 years after enrollment of the last patient
|
|
Comparison of bone marrow and peripheral blood MRD
Time Frame: From Day 15 through Day 42 of remission induction and end of therapy (At 6 months after enrollment of the last evaluable patient)
|
Parametric (linear) or non-parametric (if necessary) regression models will be fitted to analyze the relationship between the MRD levels in peripheral blood by sequencing methods and MRD levels in bone marrow (by sequencing or flow cytometry).
The peripheral blood MRD level corresponding to 0.01% in bone marrow is then obtained by solving the (regression) equation for the peripheral blood MRD level.

Isolated CNS relapse in CNS1b patients
Time Frame: 3.5 years after enrollment of the last patient
|
Traditional CNS2 patients with negative TdT and negative next-generation sequencing results will receive CNS1 therapy on TOT17.
Risk of isolated CNS relapse in this subset of patients will be compared to that in the CNS2 patients treated on TOTXV and TOTXVI, using stratified (by protocol) Gray's test.
