Combination Chemotherapy With or Without Bortezomib in Treating Younger Patients With Newly Diagnosed T-Cell Acute Lymphoblastic Leukemia or Stage II-IV T-Cell Lymphoblastic Lymphoma
Describes the nature of a clinical study. Types include:
- Observational study — observes people and measures outcomes without affecting results.
- Interventional study (clinical trial) — studies new tests, treatments, drugs, surgical procedures or devices.
- Medical records research — uses historical information collected from medical records of large groups of people to study how diseases progress and which treatments and surgeries work best.
During the early phases (phases 1 and 2), researchers assess safety, side effects, optimal dosages and risks/benefits. In the later phase (phase 3), researchers study whether the treatment works better than the current standard therapy. They also compare the safety of the new treatment with that of current treatments. Phase 3 trials include large numbers of people to make sure that the result is valid. There are also less common very early (phase 0) and later (phase 4) phases. Phase 0 trials are small trials that help researchers decide if a new agent should be tested in a phase 1 trial. Phase 4 trials look at long-term safety and effectiveness, after a new treatment has been approved and is on the market.

About this study
This randomized phase III trial compares how well combination chemotherapy works when given with or without bortezomib in treating patients with newly diagnosed T-cell acute lymphoblastic leukemia or stage II-IV T-cell lymphoblastic lymphoma. Bortezomib may help reduce the number of leukemia or lymphoma cells by blocking some of the enzymes needed for cell growth. It may also help chemotherapy work better by making cancer cells more sensitive to the drugs. It is not yet known if giving standard chemotherapy with or without bortezomib is more effective in treating T-cell acute lymphoblastic leukemia and T-cell lymphoblastic lymphoma.
Participant eligibility includes age, gender, type and stage of disease, and previous treatments or health concerns. Guidelines differ from study to study, and identify who can or cannot participate. If you need assistance understanding the eligibility criteria, please contact the study team.See eligibility criteria
- T-ALL: T-ALL patients must be enrolled on Project Every Child (APEC14B1) prior to treatment and enrollment on AALL1231
- T-LLy: if Project: Every Child (APEC14B1) is available, T-LLy patients must be enrolled on APEC14B1 prior to treatment and enrollment on AALL1231
- Patients must have newly diagnosed T-lymphoblastic leukemia (T-ALL) or T-lymphoblastic lymphoma (T-LLy) stages II-IV
- Note: a diagnosis of T-ALL is established when leukemic blasts lack myeloperoxidase or evidence of B-lineage derivation (cluster of differentiation [CD]19/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 terminal deoxynucleotidyl transferase (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-LLy 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-LLy defined by the submitting institution will be accepted
- All patients and/or their parents or legal guardians must sign a written informed consent; assent, when appropriate, will be obtained according to institutional guidelines
- Patients must not have received any cytotoxic chemotherapy for either the current diagnosis of T-ALL, T-L-Ly or for any cancer diagnosis prior to the initiation of protocol therapy on AALL1231, 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 initiating induction chemotherapy; prior exposure to ANY steroids that occurred > 28 days before the initiation of protocol therapy does not affect eligibility; the dose of prednisone or methylprednisolone does not affect eligibility
- Intrathecal cytarabine (the CNS status must be determined based on a sample obtained prior to administration of any systemic or intrathecal chemotherapy, except for steroid pretreatment) system chemotherapy must begin with 72 hours of this IT therapy; 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 use during sedation to prevent or treat airway edema
- Pre-existing >= grade 2 sensory or motor peripheral neurotoxicity
- Uncontrolled seizure disorder
- Diagnosis of Down syndrome (Trisomy 21)
- Patients who are pregnant; a pregnancy test is required for female patients of childbearing potential
- Lactating females who plan to breastfeed
- Sexually active patients of reproductive potential who have not agreed to use an effective contraceptive method for the duration of their study participation
- Patient has hypersensitivity to bortezomib, boron, or mannitol
- Serious medical or psychiatric illness likely to interfere with participation in this clinical study
- Participation in clinical trials with other investigational agents not included in this trial, within 14 days of the start of this trial and within 30 days of any dose of bortezomib
