Active clinical trials for "Leukemia"

This is a multi-center, open-label, non-controlled, non-randomized dose-escalating Phase 1 clinical study designed to examine the safety of infusing escalating doses of CNDO-109-Activated Allogeneic Natural Killer Cells-(from a first or second degree relative), after a preparatory chemotherapy regimen, in adult patients with acute myeloid leukemia (AML) who are in their first complete remission at the time of enrollment, are not candidates for stem cell transplant, and are considered to be at high risk for recurrence.

Rationale New chemotherapeutic agents are needed in relapsing B-Cell Chronic Lymphocytic Leukemia (B-CLL) to overcome resistance of CLL cells. Valproic acid (VPA) is an inhibitor of histone deacetylase (HDAC) used as an anticonvulsant and mood-stabilizing drug for decades. VPA mediates apoptosis in CLL cells through caspase activation. VPA shows toxicity toward CLL cells displaying alterations in the p53 pathway. The combination of VPA with fludarabine or 2-Chlorodeoxyadenosine (CdA, Cladribine) results in synergistic loss of B-CLL cell viability, and significant increase in apoptosis. The highest index of synergism is observed between VPA and CdA, a purine nucleoside analog active in B-CLL. Study design Overall, the study will be proposed to previously treated patients with advanced B-CLL, who are not eligible for aggressive approaches, and who exhibit progressive disease. A total of 33 patients will be included. Estimated enrolment time is 2 years. First part: It is planned to start therapy with single VPA during 2 months, targeting plasma levels that have been reported to be active in vitro toward CLL cells (but that do not exceed therapeutic levels in seizure prevention), and in parallel, to verify whether cellular targets of VPA have been actually inhibited in leukemic B-lymphocytes. Second part: After the VPA preloading period (2 months), patients will be evaluated to receive CdA. CdA will be given at 5.6 mg/m²/day intravenously during 3 days, a reduced-dose schedule which is less toxic - at no obvious cost of loss of efficacy - as compared to the standard dosage of 5 days. CdA was chosen because it displays the highest level of in vitro synergism with VPA. Four monthly courses of CdA will be given. Patients will then be evaluated. VPA will be stopped at the time of response evaluation (scheduled 28 days after the last course of CdA).

To compare the antitumor efficacy and toxicity of Idarubicin and cytarabine in combination with or not with infusions of granulocyte colony-stimulating factor-mobilized HLA-mismatched donor peripheral blood stem cells in patients with newly diagnosed high-risk acute myeloid leukemia (AML).

The purpose of this study is to evaluate the safety and the efficacy of combined treatment strategy of WT1ASCI, infusion of ex vivo regulatory T cells depleted T lymphocytes and in vivo regulatory T cells depletion as post-consolidation therapy in patients with WT1-positive Acute Myeloid Leukemia. The study will also evaluate the clinical activity and immune response of this approach in bad risk patients in CR1 and all patients in CR2 or CR3, non eligible for an allogeneic Hematopoietic Stem Cell Transplantation

The purpose of this study is to determine how well SNS01-T is tolerated by relapsed or refractory multiple myeloma, B cell lymphoma or plasma cell leukemia patients when given by intravenous infusion at various doses.

This is a two-part, open-label, Phase I/II study in subjects with relapsed or refractory TdT-positive leukemia for which no standard therapies are expected to result in durable remission.

RATIONALE: Studying samples of blood in the laboratory from patients with cancer may help doctors learn more about nausea and vomiting caused by cancer treatment. PURPOSE: This laboratory study is looking at blood samples from patients with cancer who were treated on a clinical trial to control nausea and vomiting during donor stem cell transplant.

This is a multicentric, non-randomized, non-controlled open-label phase II trial to evaluate the safety and efficacy of treosulfan in a combination regimen with fludarabine as conditioning therapy prior to allogeneic stem cell transplantation (SCT) in patients with haematological malignancies. The aim is to demonstrate a clinical benefit compared with historical data on intravenous busulfan (BusulfexTM, BusilvexTM), the only drug so far registered in the indication conditioning before allogeneic stem cell transplantation.

Primary study objective is the evaluation of efficacy of autologous hematopoietic cell transplantation (HCT) with core-binding factor (CBF) positive acute myeloid leukemia (AML) in the first CR (CR1) in terms of relapse incidence (cumulative incidence of relapse, CIR) and disease-free survival (DFS). Secondary study objectives are the engraftment rate / time to engraftment, transplantation-related mortality (TRM) rate, event-free survival (EFS) rate, and Overall survival (OS).

The purpose of this study is to show that myeloablative hematopoietic progenitor cell transplantation (HPCT) continues to offer acceptable disease-free survival for select patients requiring HPCT.
