Investigator standingUNKNOWN

We have no verifiable track record for the investigator named on this trial. That is common for early-career investigators and for records held outside ClinicalTrials.gov — it is not a negative signal.

How this score is built

Investigator standing0/100
No investigator recorded in the registry for this trial

These describe the registry record only, and today we hold ClinicalTrials.gov data. Absent fields lower a score, and absence often reflects registration practice rather than study quality. A high-stature trial is not necessarily safer or a better choice for you — enrolling in a large definitive trial can mean a higher chance of receiving placebo, while a small early-phase study may be the only route to a new therapy.

Zusammenfassung

This phase III trial studies whether inotuzumab ozogamicin added to post-induction chemotherapy and immunotherapy (chemo-immunotherapy) for patients with High-Risk B-cell Acute Lymphoblastic Leukemia (B-ALL) improves outcomes. Inotuzumab ozogamicin is a monoclonal antibody, which is a type of protein that can bind to certain targets on the surface of cells. Inotuzumab ozogamicin is a monoclonal antibody that is linked to a type of chemotherapy called calicheamicin. Inotuzumab attaches to cancer cells by binding to the CD22 protein on the surface of the cancer cell and delivering calicheamicin inside the cells to kill them. Other drugs used in the chemotherapy regimen, such as cyclophosphamide, cytarabine, dexamethasone, doxorubicin, daunorubicin, methotrexate, leucovorin, mercaptopurine, prednisone, thioguanine, vincristine, and pegaspargase or calaspargase pegol work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Blinatumomab is a specialized type of monoclonal antibody known as a bispecific T-cell engager (BiTE). It works by simultaneously binding to CD19 on cancer cells and CD3 on normal immune cells, bringing them together to destroy leukemia cells. Blinatumomab is a standard part of chemo-immunotherapy treatment for B-ALL. This trial also studies the outcomes of patients with mixed phenotype acute leukemia (MPAL), and B-lymphoblastic lymphoma (B-LLy) when treated with ALL therapy without inotuzumab ozogamicin or blinatumomab. The overall goal of this study is to understand if adding inotuzumab ozogamicin to standard of care chemo-immunotherapy maintains or improves outcomes in High Risk B-cell Acute Lymphoblastic Leukemia (HR B-ALL). The first part of the study includes the first phase of therapy: Induction. This part will collect information on the leukemia, as well as the effects of the initial treatment, to classify patients into post-induction treatment groups. On the second part of this study, patients with HR B-ALL will receive the remainder of the chemotherapy cycles (consolidation, blinatumomab block 1, interim maintenance 1, blinatumomab block 2, delayed intensification, interim maintenance 2, maintenance), with some patients randomized to receive inotuzumab. The patients that receive inotuzumab will not receive part of consolidation or part of delayed intensification. Other aims of this study include evaluating 1) side effects of treatment using patient-reported outcomes and health-related quality of life, 2) the best ways to help patients adhere to oral chemotherapy regimens, 3) the relationship between levels of inotuzumab ozogamicin in the blood and side effects, 4) the impact of chemo-immunotherapy on the immune system and risk of infection, and 5) the impact of social determinants of health on outcomes. Finally, this study will be the first to track the outcomes of subjects with disseminated B-cell Lymphoblastic Leukemia (B-LLy) or Mixed Phenotype Acute Leukemia (MPAL) when treated with B-ALL chemotherapy.

PRIMARY OBJECTIVE: I. To compare in a randomized manner the post-induction 5-year event-free survival (EFS) for children and young adults with High Risk (HR) B-cell acute lymphoblastic leukemia (B-ALL) treated with a modified Berlin-Frankfurt-Münster (mBFM) chemo-immunotherapy backbone that includes blinatumomab and replaces Consolidation Part 2 and Delayed Intensification (DI) Part 2 with two blocks of inotuzumab ozogamicin, versus those treated with a full mBFM chemo-immunotherapy backbone that includes blinatumomab and retains Consolidation Part 2 and DI Part 2 without the addition of inotuzumab ozogamicin. SECONDARY OBJECTIVES: I. To describe the 5-year disease-free survival (DFS) for a favorable risk subset of National Cancer Institute (NCI) HR B-ALL (HR-Fav) when treated with mBFM chemotherapy with a single high-dose methotrexate (HD-MTX) interim maintenance (IM) phase and treatment duration of 2 years from the start of IM regardless of sex. (Pre-Amendment #7B) II. To determine the toxicity and tolerability of inotuzumab ozogamicin integrated into the mBFM chemotherapy backbone in HR B-ALL, including toxicity experienced during phases of therapy subsequent to inotuzumab ozogamicin. III. To describe the 5-year event-free survival (EFS) for patients with mixed phenotype acute leukemia (MPAL) receiving mBFM HR B-ALL therapy that includes a second IM phase with Capizzi intravenous (IV) methotrexate without leucovorin rescue plus pegaspargase or calaspargase pegol (C-MTX). IV. To describe the 5-year EFS for patients with disseminated (Murphy stage III-IV) B-cell lymphoblastic lymphoma (B-LLy) receiving mBFM HR B-ALL therapy that includes a second IM phase with C-MTX. V. To compare health-related quality of life (HRQoL) for randomized HR B-ALL patients by study arm at two defined time points: Consolidation Part 2 Day 43 (Arm D)/inotuzumab ozogamicin Block 1 Day 15 (Arm E) and day 1 of IM2 (Arms D and E). VI. To compare symptomatic adverse events (AEs) for patients with HR B-ALL by study arm using Patient Reported Outcome (PRO) Measures. EXPLORATORY OBJECTIVES: I. To describe the 5-year overall survival (OS) and cumulative incidence of relapse (CIR) for randomized patients with HR B-ALL. II. To describe the therapy administered, disease response, and survival outcomes of patients with MPAL who come off protocol therapy due to poor disease response to ALL therapy either during Induction, at end of induction (EOI), or at end of consolidation (EOC). III. To define the prevalence and significance of minimal marrow disease (MMD) at diagnosis and bone marrow minimal residual disease (MRD) at EOI in disseminated B-LLy. IV. To determine the impact of proposed adherence-enhancing interventions on adherence to oral mercaptopurine in patients with ALL. V. To characterize the pharmacokinetics (PK) of inotuzumab ozogamicin when administered in the setting of first remission in pediatric and young adult patients with HR B-ALL. VI. To explore associations between family-reported social determinants of health and survival outcomes, toxicities, and blinatumomab patterns of delivery. VII. To describe both the short- and long-term impact of chemo-immunotherapy on measures of immune function and infectious toxicities.

Inclusion Criteria: * B-ALL and MPAL patients must be enrolled on APEC14B1 and consented to eligibility studies (Part A) prior to treatment and enrollment on AALL1732. Note that central confirmation of MPAL diagnosis must occur within 22 days of enrollment for suspected MPAL patients. If not performed within this time frame, patients will be taken off protocol. * APEC14B1 is not a requirement for B-LLy patients but for institutional compliance every patient should be offered participation in APEC14B1. B-LLy patients may directly enroll on AALL1732. * Patients must be \> 365 days and \< 25 years of age * Initial white blood cell count (WBC) criteria for patients with B-ALL (within 7 days prior to the start of protocol-directed systemic therapy): * Age 1-9.99 years: WBC \>= 50,000/uL * Age 10-24.99 years: Any WBC * Age 1-9.99 years: WBC \< 50,000/uL with one or more of the following: * Testicular leukemia * CNS leukemia (CNS3) * Steroid pretreatment. * Initial white blood cell count (WBC) criteria for patients with MPAL (within 7 days prior to the start of protocol-directed systemic therapy): * Age 1-24.99 years: any WBC NOTE: Patients enrolled as suspected MPAL but found on central confirmatory testing to have B-ALL must meet the B-ALL criteria above (age, WBC, extramedullary disease, steroid pretreatment) to switch to the B-ALL stratum before the end of induction. * Patient has newly diagnosed B-ALL or MPAL (by World Health Organization \[WHO\] 2016 criteria) with \>= 25% blasts on a bone marrow (BM) aspirate; * OR If a BM aspirate is not obtained or is not diagnostic of acute leukemia, the diagnosis can be established by a pathologic diagnosis of acute leukemia on a BM biopsy; * OR A complete blood count (CBC) documenting the presence of at least 1,000/uL circulating leukemic cells if a bone marrow aspirate or biopsy cannot be performed. * Patient has newly diagnosed B-LLy Murphy stages III or IV. * Patient has newly diagnosed B-LLy Murphy stages I or II with steroid pretreatment. * Note: For B-LLy patients with tissue available for flow cytometry, the criterion for diagnosis should be analogous to B-ALL. For tissue processed by other means (i.e., paraffin blocks), the methodology and criteria for immunophenotypic analysis to establish the diagnosis of B-LLy defined by the submitting institution will be accepted. * Central nervous system (CNS) status must be determined prior to enrollment based on a sample obtained prior to administration of any systemic or intrathecal chemotherapy, except for steroid pretreatment and cytoreduction. Note that once cerebrospinal fluid (CSF) has been collected, protocol therapy can be initiated while final determination of CNS status is pending. It is recommended that intrathecal cytarabine be administered at the time of the diagnostic lumbar puncture. This is usually done at the time of the diagnostic bone marrow or venous line placement to avoid a second lumbar puncture. This is allowed prior to enrollment. Systemic chemotherapy must begin within 72 hours of this intrathecal therapy. * Direct bilirubin \< 2.0 mg/dL (34 micromoles/L) * Alanine aminotransferase (ALT) ≤ 10x upper limit of normal (ULN). For the purposes of this study, the ULN for ALT is defined as 45 U/L * Exceptions to this include patients with known Gilbert's Syndrome, or those with hepatic involvement from leukemic or lymphomatous infiltration * All patients and/or their parents or legal guardians must sign a written informed consent. * All institutional, Food and Drug Administration (FDA), and NCI requirements for human studies must be met. Exclusion Criteria: * Patients with Down syndrome are not eligible * With the exception of steroid pretreatment and steroid cytoreduction or the administration of intrathecal cytarabine, patients must not have received any prior cytotoxic chemotherapy for the current diagnosis of B-ALL, MPAL, or B-LLy or for any cancer diagnosed prior to initiation of protocol therapy on AALL1732. * Patients who have received \> 72 hours of hydroxyurea within one week prior to start of systemic protocol therapy. * Patients with B-ALL or MPAL who do not have sufficient diagnostic bone marrow submitted for APEC14B1 testing and who do not have a peripheral blood sample submitted containing \> 1,000/uL circulating leukemia cells. * Patients with acute undifferentiated leukemia (AUL) are not eligible. * For Murphy stage III/IV B-LLy patients, or stage I/II patients with steroid pretreatment, the following additional exclusion criteria apply: * T-lymphoblastic lymphoma. * Morphologically unclassifiable lymphoma. * Absence of both B-cell and T-cell phenotype markers in a case submitted as lymphoblastic lymphoma. * Patients with known Charcot-Marie-Tooth disease. * Patients with known MYC translocation associated with mature (Burkitt) B-cell ALL, regardless of blast immunophenotype. * Patients requiring radiation at diagnosis. * 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 women who plan to breastfeed their infants while on study and for 2 months after the last dose of inotuzumab ozogamicin. * Sexually active patients of reproductive potential who have not agreed to use an effective contraceptive method for the duration of study participation. For those patients randomized to inotuzumab ozogamicin, there is a minimum of 8 months after the last dose of inotuzumab ozogamicin for females and 5 months after the last dose of inotuzumab ozogamicin for males.

Sonstiger Endpunkt
Impact of four proposed interventions of varying intensities to enhance adherence to oral 6 mercaptopurine, with a randomization based upon baseline adherence measured during the first cycle of maintenance therapy
The main analyses will use mixed models including random effects to account for the multiple sites and longitudinal observations within patients. Will examine unadjusted associations of the primary outcome (MEMS-based adherence rate) with demographic, clinical and sociodemographic variables for the entire cohort (across 3 intervention arms). Those patient-level factors associated with the outcome will be included in the main model as fixed effects to improve the precision of the estimates. The basic model for adherence will include time and mean adherence during the baseline pre-intervention period and treatment group. It will also include interactions between time and both baseline adherence and intervention group to allow for intervention-specific trends and normal changes in adherence over time.
