Detailed Description
PRIMARY OBJECTIVES:
I. To compare the event-free survival (EFS) from the end of induction (EOI) in patients with newly diagnosed T-ALL who are randomized to either receive a modified augmented Berlin-Frankfurt-Münster (aBFM) chemotherapy backbone or a modified aBFM backbone with the addition of daratumumab.
II. To compare the EFS from the EOI in patients with newly diagnosed T-LL who are randomized to a modified aBFM chemotherapy backbone with bortezomib or to a modified aBFM backbone with bortezomib and the addition of daratumumab.
SECONDARY OBJECTIVES:
I. To compare health-related quality of life (HRQoL) and therapy-related toxicity and tolerability between patients with T-ALL or T-LL randomized to a modified aBFM backbone or to a modified aBFM backbone with the addition of daratumumab.
II. To compare overall survival (OS) from date of randomization in patients with newly diagnosed T-ALL who are randomized to either receive a modified aBFM chemotherapy backbone or a modified aBFM backbone with the addition of daratumumab.
III. To compare OS from date of randomization in patients with newly diagnosed T-LL who are randomized to a modified aBFM chemotherapy backbone with bortezomib or to a modified aBFM backbone with bortezomib and the addition of daratumumab.
EXPLORATORY OBJECTIVES:
I. In patients with newly diagnosed T-LL, to determine if minimal residual disease (MRD) testing at EOI can predict EFS and/or OS.
II. In T-ALL patients, to describe changes in the immunophenotype (specifically CD38 surface expression on T-ALL/T-LL blasts) and for the development of anti-daratumumab antibodies over the course of treatment and correlate changes with clinical outcomes and demographic variables.
III. To explore the associations between family-reported social determinants of health and both clinical outcomes (including incidence of treatment-related toxicities, EFS, OS), and leukemia/lymphoma and host biology.
IV. To describe outcome differences (EFS and OS) in patients with T-LL who differ in degrees of positron emission tomography (PET)-imaging avid disease at the EOI.
V. To explore potential imaging findings and biomarkers of significant/severe nelarabine-induced central nervous system toxicities by central review of magnetic resonance imaging (MRI) and to investigate possible clinical features in patients experiencing such toxicities.
VI. To bank peripheral blood specimens for future correlative studies in patients with T-LL.
VII. To compare EFS and OS from the EOI in patients with newly diagnosed T-ALL who are MRD positive (≥ 0.01%) at the EOI to those who are MRD negative at the EOI.

Description
Inclusion Criteria:
- All patients must be enrolled on APEC14B1 and consented to eligibility screening (part A) prior to treatment and enrolled on AALL2331.
- Patients must be > 365 days and < 21 years of age at the time of diagnosis.
* Newly diagnosed T-cell acute lymphoblastic leukemia (T-ALL) or T-lineage lymphoblastic lymphoma (T-LL) stages II-IV.
- Note: A diagnosis of T-ALL is established when leukemic blasts lack myeloperoxidase or evidence of B-lineage derivation (CD19/CD22/CD20), and express either surface or cytoplasmic CD3 or two or more of the antigens CD8, CD7, CD5, CD4, CD2 or CD1a, and are present either in peripheral blood or > 25% in the bone marrow. If surface CD3 is expressed on all leukemic cells, additional markers of immaturity, including TdT, CD34 or CD99 will be assessed for expression. Cases with uncertain expression will receive additional review within the appropriate Children's Oncology Group (COG) reference laboratory.
- For T-LL patients with tissue available for flow cytometry, the criterion for diagnosis should be analogous to T-ALL. For tissue processed by other means (i.e. paraffin blocks), the methodology and criteria for immunophenotypic analysis to establish the diagnosis of T-LL defined by the submitting institution will be accepted.
Exclusion Criteria:
- Diagnosis of Down syndrome (trisomy 21).
- Patients with known Charcot-Marie-Tooth disease.
* Patients must not have received any cytotoxic chemotherapy for either the current diagnosis of T-ALL, T-LL or for any cancer diagnosis prior to the initiation of protocol therapy on AALL2331 with the exception of:
- Steroid pretreatment: Prednisone or methylprednisolone for ≤ 120 hours (5 days) in the 7 days prior to initiating induction chemotherapy or for ≤ 336 hours (14 days) in the 28 days prior to initiation of protocol therapy does not affect eligibility.
- Intrathecal cytarabine; or
- Pretreatment with hydroxyurea; or
- 600 cGy of chest irradiation, if medically necessary.
- Pre-treatment with dexamethasone in the 28 days prior to initiation of protocol therapy is not allowed with the exception of a single dose of dexamethasone used during sedation to prevent or treat airway edema. Patients who receive a single dose of dexamethasone to prevent or treat airway edema in the 28 days preceding diagnosis are eligible for this study.
* Female patients who are pregnant since fetal toxicities and teratogenic effects have been noted for several of the study drugs. A pregnancy test is required for female patients of childbearing potential.
- Lactating females who plan to breastfeed their infants.
- Sexually active patients of reproductive potential who have not agreed to use an effective contraceptive method for the duration of their study participation.
- Known severe persistent asthma anytime in the previous two years or uncontrolled asthma of any classification.
- Peripheral neurotoxicity: Pre-existing ≥ grade 2 sensory or motor peripheral neurotoxicity.
- Seizure disorder: Patients must not have an uncontrolled seizure disorder. Patients with a seizure history or a controlled seizure disorder are eligible.

Event-free survival (EFS) in patients with newly diagnosed T-cell lymphoblastic leukemia (T-ALL)
Time Frame: From date of randomization (randomization conducted at the end of induction [EOI]) to date of first event (consolidation failure, interim maintenance failure, relapse, secondary malignant neoplasm [SMN], death from any cause), assessed up to 4 years
|
Will compare EFS in patients with newly diagnosed T-ALL who are randomized to either receive a modified augmented Berlin-Frankfurt-Munich (aBFM) chemotherapy backbone or a modified aBFM backbone with the addition of daratumumab.

Magnetic resonance imaging (MRI) imaging findings associated with onset of seizure or grade 3 or higher neurotoxicity attributed to treatment with nelarabine
Time Frame: Assessed to the end of protocol therapy, up to 3 years.
|
Will explore potential MRI imaging findings that are associated with severe nelarabine-induced central nervous system toxicities.
In T-ALL patients that experience any new onset seizure or grade 3 or higher neurotoxicity attributed to treatment with nelarabine, results of MRI imaging and other biomarkers associated with toxicity and associations with clinical features will be described to determine potential risk factors.
These analyses will be based on analysis of variance, test of proportions, log-rank test, semi-parametric or parametric survival analysis methods, etc., as appropriate.
MRI findings will be analyzed to identify a pathognomonic signal of nelarabine neurotoxicity.
In addition it is anticipated that MRIs obtained for this purpose will have signals which will exclude neurotoxic events related to non-nelarabine therapeutics.
