B-Cell Acute Lymphoblastic Leukemia clinical trials at University of California Health

This phase II trial studies how well inotuzumab ozogamicin works in treating younger patients with B-lymphoblastic lymphoma or CD22 positive B acute lymphoblastic leukemia that has come back (relapsed) or does not respond to treatment (refractory). Inotuzumab ozogamicin is a monoclonal antibody, called inotuzumab, linked to a toxic agent called ozogamicin. Inotuzumab attaches to CD22 positive cancer cells in a targeted way and delivers ozogamicin to kill them.

This phase III trial studies how well blinatumomab works in combination with chemotherapy in treating patients with newly diagnosed, standard risk B-lymphoblastic leukemia or B-lymphoblastic lymphoma with or without Down syndrome. Monoclonal antibodies, such as blinatumomab, may induce changes in the body's immune system and may interfere with the ability of cancer cells to grow and spread. Chemotherapy drugs, such as vincristine, dexamethasone, prednisone, prednisolone, pegaspargase, methotrexate, cytarabine, mercaptopurine, doxorubicin, cyclophosphamide, and thioguanine, 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. Leucovorin decreases the toxic effects of methotrexate. Giving monoclonal antibody therapy with chemotherapy may kill more cancer cells. Giving blinatumomab and combination chemotherapy may work better than combination chemotherapy alone in treating patients with B-ALL. This trial also assigns patients into different chemotherapy treatment regimens based on risk (the chance of cancer returning after treatment). Treating patients with chemotherapy based on risk may help doctors decide which patients can best benefit from which chemotherapy treatment regimens.

This phase III trial studies whether inotuzumab ozogamicin added to post-induction chemotherapy for patients with High-Risk B-cell Acute Lymphoblastic Leukemia (B-ALL) improves outcomes. 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. Inotuzumab ozogamicin is a monoclonal antibody, called inotuzumab, linked to a type of chemotherapy called calicheamicin. Inotuzumab attaches to cancer cells in a targeted way and delivers calicheamicin 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. This trial will also study the outcomes of patients with mixed phenotype acute leukemia (MPAL) and disseminated B lymphoblastic lymphoma (B-LLy) when treated with high-risk ALL chemotherapy. The overall goal of this study is to understand if adding inotuzumab ozogamicin to standard of care chemotherapy maintains or improves outcomes in High Risk B-cell Acute Lymphoblastic Leukemia (HR B-ALL). The first part of the study includes the first two phases of therapy: Induction and Consolidation. This part will collect information on the leukemia, as well as the effects of the initial treatment, to classify patients into post-consolidation treatment groups. On the second part of this study, patients with HR B-ALL will receive the remainder of the chemotherapy cycles (interim maintenance I, delayed intensification, interim maintenance II, maintenance), with some patients randomized to receive inotuzumab. The patients that receive inotuzumab will not receive part of delayed intensification. Other aims of this study include investigating whether treating both males and females with the same duration of chemotherapy maintains outcomes for males who have previously been treated for an additional year compared to girls, as well as to evaluate the best ways to help patients adhere to oral chemotherapy regimens. 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.
