Active clinical trials for "Precursor Cell Lymphoblastic Leukemia-Lymphoma"

A Non-randomized, prospective , multicenter, open uncontrolled study in patients with acute myelogenous (AML) or lymphoblastic leukaemia (ALL)

This is a pilot study utilizing Marqibo® (vincristine sulfate liposome injection) combined with dexamethasone, mitoxantrone and asparaginase (UK ALL R3) for relapsed acute lymphoblastic leukemia (ALL).

Treatment of pediatric acute lymphoblastic leukemia (ALL) has advanced and the overall survival exceeds 80% nowadays. However the overall survival of high risk ALL remains 75-90%, thus recent studies focus on treatment intensification according to the risk group. According to the previous reports, we designed a multicenter prospective trial for pediatric ALL.

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 is the second stage of the previous anti-CD19 CAR-T therapy (NCT02965092). The study aims to evaluate the safety and efficacy of consolidative allo-HSCT following CAR-T therapy in patients with relapsed or refractory B cell Malignancies.

Prospectively evaluate the safety and effectiveness of CD19/CD22 dual-target CAR-T cells in the treatment of relapsed/refractory B-cell acute lymphoblastic leukemia.

This study is an open, dose-escalating clinical study, taking patients with relapsed or refractory acute lymphoblastic leukemia as the test subjects, including mouse-derived CAR-T treatment failure or relapse, or for any reason cannot bridge the transplant r/r B-ALL.

This is a phase I clinical study to evaluate the safety and tolerability of pCAR-19B in adults with relapsed or refractory B-ALL, and to obtain the maximum tolerated dose of pCAR-19B and phase II Recommended dose.

This phase I trial studies the side effects and best way to give natural killer cells and donor umbilical cord blood transplant in treating patients with hematological malignancies. Giving chemotherapy with or without total body irradiation before a donor umbilical cord blood transplant helps stop the growth of cancer cells. It may also stop the patient's immune system from rejecting the donor's stem cells. When the healthy stem cells and natural killer cells from a donor are infused into the patient they may help the patient's bone marrow make stem cells, red blood cells, white blood cells, and platelets.

Background: Allogeneic hematopoietic stem cell transplantation (or allotransplant; donor blood stem cells) have been used with varying degrees of success as an immune therapy for blood-system cancers (leukemias, myelodysplastic syndrome, lymphomas, multiple myeloma, etc.). Some people s cancer remains active (comes back or continues to spread) after an allotransplant, while other peoples cancer disappears and they are hopefully cured. National Institutes of Health (NIH) researchers are studying the reasons for these different treatment outcomes, and trying to develop better cancer treatments for people with active cancer after allotransplant. Researchers are collecting data from people who have had allotransplants for a cancer of the blood, whether or not the cancer is in remission, and from their donors. Those with active cancers may be eligible to participate in one of several NIH studies testing treatments for active cancer after allotransplant. Objectives: To develop a systematic, comprehensive evaluation of individuals with relapsed malignant blood cancers after allotransplant (and, if available, their donors) to identify potential treatment study options To compare the immune system after allotransplant between people whose cancers are growing with people whose cancers remain in remission. To compare the immune system after cancer relapse/progression treatment between people whose cancer responds to treatment with those whose cancers continue to grow. Eligibility: Individuals whose blood system cancer grows or comes back after receiving allotransplant treatment. Individuals whose blood system cancer is responding or in remission 100 days or more after receiving allotransplant treatment. Related stem-cell donors of eligible allotransplant recipients. Design: Participants will be evaluated with a full physical examination, detailed medical history (for recipients, including a history of allotransplant treatment process, side-effects, etc.), and blood tests. Recipients will also have imaging studies, possible tissue biopsies, quality of life questionnaires/assessments, and other tests to evaluate the current state of their cancer, whether active or in remission. In some cases, it may be possible to substitute results from recent tests and/or biopsies. Healthy related donors will have apheresis to provide white blood cells for study and/or for use in potential treatment options. If stem cells would be medically helpful to a recipient, their donors might be asked to take injections of filgrastim before the apheresis procedure to stimulate the production of stem cells for collection. As feasible, all recipients will be asked to return to the NIH for detailed follow-up visits in conjunction with 6, 12, and 24 months post-allotransplant evaluations, and may be monitored between visits. Recipients whose cancers are active and who are found to be eligible for treatment protocols at the NIH will continue to be monitored on this study while participating on treatment protocols. Return visits and follow-up tests for this study will be coordinated with those required by the treatment protocol. Participants may return in the future to be evaluated for new treatment study options (recipients) or additional cell donations for therapy (donors).
