Filter by:This study aimed to investigate the performance of next-generation sequencing (NGS) techniques measuring immunoglobulin heavy chain (IgH)-variable, diversity, and joining (V[D]J) clonal rearrangements （IgH-V[D]J NGS） compared with flow cytometry (FCM) in detecting of minimal residual disease (MRD) for children with acute lymphoblastic leukemia treated with South Chinese Children Leukemia Group (SCCLG)-ALL 2016, and to predict the relapse of the disease in the early stage and to assess the prognosis, so as to provide the basis for early intervention treatment and reduce the hematological relapse and improve the survival rate.
This phase Ib trial studies the effects of venetoclax in combination with dasatinib, prednisone, rituximab and blinatumomab in treating patients with Philadelphia chromosome positive acute lymphoblastic leukemia (ALL) that is newly diagnosed or that has come back (relapsed). Venetoclax may stop the growth of cancer cells by blocking Bcl-2, a protein needed for cancer cell survival. Dasatinib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Anti-inflammatory drugs, such as prednisone lower the body's immune response and are used with other drugs in the treatment of some types of cancer. Rituximab and blinatumomab are monoclonal antibody that may interfere with the ability of cancer cells to grow and spread. Giving venetoclax in combination with dasatinib, prednisone, and rituximab and blinatumomab may help treat patients with newly diagnosed or relapsed Philadelphia chromosome positive acute lymphoblastic leukemia.
PBLTT52CAR19 modified T cells are allogenic engineered human T cells (defined as TT52CAR19 +TCRαβ-) prepared for the treatment of CD19+ B cell leukaemia. The cells are from healthy adult volunteer donors and are not HLA-matched. They have been transduced to express and anti-CD19 chimeric antigen receptor (CAR19) using a lentiviral vector that also incorporates CRISPR guides for genome editing of CD52 and TRAC loci in the presence of transiently provided Cas9. Recognition by TT52CAR19 T cells mediates eradication of CD19+ leukaemia and other CD19+ B cells through T cell mediated cytotoxicity. This study aims to apply PBLTT52CAR19 T cells to secure molecular remission in children with relapsed/refractory B-ALL ahead of programmed allogeneic stem cell transplantation. The cells are to be used in a time-limited manner for their anti-leukaemia effects and then depleted by standard pre- transplant conditioning.
CD19 is expressed in most B malignant tumors, especially in the former B cells ALL. This makes CD19 a natural target of immunotherapy. In terms of safety, the lack of B cells caused by CD19 targeted therapy will not cause life-threatening side effects (of course, Ig supplementation is necessary in the long-term B cell inhibition therapy). Moreover, the number of B cells can be restored after removing anti-CD19 treatment measures (such as anti-CD19 CART cells). In addition, CD19 has been chosen as the target of B-ALL therapy for the following reasons: ① as the BCR signal "amplifier", CD19 plays a role in PAX-5-mediated tumor formation; ② by activating MYC (as the oncogene controlled by PAX-5, C-MYC plays a key role in promoting the malignant proliferation of B cells), CD19 can cause B-ALL formation. Based on the above reasons, CD19 has become an ideal target in the treatment of B-cell cancer.
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.
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.
The goal of this phase II clinical study is to learn about the safety of inotuzumab ozogamicin when given with fludarabine, with or without bendamustine, melphalan, and rituximab before and after a stem cell transplant. Researchers also want to learn if inotuzumab ozogamicin when given after a stem cell transplant can help control leukemia and lymphoma. Inotuzumab ozogamicin is a monoclonal antibody, called inotuzumab, linked to a chemotherapy drug called ozogamicin. Inotuzumab attaches to CD22-positive cancer cells in a targeted way and delivers ozogamicin to kill them. Giving chemotherapy before a bone marrow or peripheral blood stem cell transplant helps stop the growth of cells in the bone marrow, including normal blood-forming cells (stem cells) and cancer cells. Sometimes the transplanted cells from a donor attack the body's normal cells (called graft-versus-host disease). Giving tacrolimus and filgrastim before or after the transplant may stop this from happening. Fludarabine, bendamustine, melphalan, and rituximab are commonly given before stem cell transplants. Giving inotuzumab ozogamicin with chemotherapy may work better in treating patients with leukemia or lymphoma undergoing stem cell transplantation.
This phase Ib/II clinical trial studies the side effects and best dose of venetoclax and how well it works when given together with vincristine liposomal in treating patients with T-cell or B-cell acute lymphoblastic leukemia that has come back or does not respond to treatment. Venetoclax may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as vincristine liposomal, 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. Giving venetoclax together with vincristine liposomal may work better in treating patients with acute lymphoblastic leukemia.
This phase II trial studies how well combination chemotherapy and inotuzumab ozogamicin work in treating patients with B acute lymphoblastic leukemia. Drugs used in chemotherapy, such as cyclophosphamide, vincristine sulfate, doxorubicin hydrochloride, dexamethasone, methotrexate and cytarabine, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Immunotherapy with monoclonal antibodies, such as inotuzumab ozogamicin, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Giving combination chemotherapy and inotuzumab ozogamicin may work better at treating B acute lymphoblastic leukemia.
This phase II trial studies how well inotuzumab ozogamicin works in treating patients with B-cell acute lymphocytic leukemia with positive minimal residual disease. Inotuzumab ozogamicin is a monoclonal antibody called inotuzumab linked to a toxic agent called ozogamicin. Inotuzumab ozogamicin attaches to B cell-specific CD22 cancer cells in a targeted way and kills them.
