Active clinical trials for "Leukemia, Lymphocytic, Chronic, B-Cell"

Chimeric antigen receptor (CAR) T cells targeting CD19 will be evaluated for safety and efficacy in patients with B cell malignancy including lymphoma or leukemia.

This study involves adding the kinase inhibitor Ruxolitinib to Ibrutinib to treat Chronic Lymphocytic Leukemia (CLL).

This is a single-arm open-label phase I study to determine the effect of CD19- CAR-T Cells infusion followed by allogeneic stem cell transplantation in safety, efficacy and engraftment potential in patients with CD19+ B-lineage leukemia and lymphoma.

This study will provide long-term follow-up for patients who have received treatment with a Juno CAR T-cell product in a Juno-sponsored clinical trial. In this study, patients will be followed for up to 15 years after their last dose of Juno CAR T cells for evaluation of delayed adverse events, presence of persisting CAR T-cell vector sequences, presence of replication-competent retrovirus (RCR) or lentivirus (RCL), and survival.

Protocol YY-20394-001 is a phase I open-label, first in human, dose escalation study to assess the tolerability, pharmacokinetics (PK) and efficacy of YY-20394 in patients with relapse or refractory B cell malignant hematological tumor.

Relapsed and refractory B cell malignancies show unfavorable prognosis, especially for adult patients. Now, there is no standard management for these patients. Induced-T cell-like NK cells with chimeric antigen receptor (CAR-ITNK cells) is a promising treatment option for treating B cell derived malignancy. The purpose of this study is to evaluate the efficacy and safety of CAR-ITNK cells infusions in patients with relapsed and refractory B cell malignancies.

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).

The purpose of this study is to determine whether Valproic acid, as a single agent is effective in the treatment of Chronic Lymphocytic Leukemia which has relapsed or is refractory to therapy with standard drugs.

The purpose of this study is to determine whether Milatuzumab is effective in patients with refractory chronic lymphocytic leukemia, and also to find out in which range of doses is a response seen.

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.
