Filter by: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).
This is a Phase I, multicenter, open-label, dose-escalation study of polatuzumab vedotin administered as a single agent by intravenous (IV) infusion to participants with relapsed or refractory hematologic malignancies. In Phase Ib, participants will receive polatuzumab vedotin in combination with rituximab.
The purpose of this study is to assess the bioequivalence of subcutaneous Vidaza® and subcutaneous Luitpold Azacitidine pharmacokinetics and to assess the comparative safety of subcutaneous Vidaza® versus subcutaneous Luitpold Azacitidine.
Allogeneic transplant from a matched sibling for the treatment of a variety of illnesses including bone marrow failure states, leukemias, myelodysplastic or myeloproliferative syndromes, lymphoma, or myeloma using a nonmyeloablative preparative regimen.
This phase II clinical trial is studying how well lenalidomide works in treating patients with high-risk chronic lymphocytic leukemia. Biological therapies, such as lenalidomide, may stimulate the immune system in different ways and stop cancer cells from growing.
Chronic lymphocytic leukemia (CLL) is increasingly believed to be closely related to chronic stimulation of healthy B-cells. Identification of antigen(s) are relevant for the stimulation of CLL precursor cells is therefore of high interest. The investigators found recently evidence that a herpes virus is involved in this process of stimulation. Consequently, elimination of the antigenic stimulation of leukemic cells by this herpes virus may be expected to reduce or even inhibit propagation of leukemic cells. The investigators hypothesize that inhibition of CMV replication by a short course of antiviral treatment may reduce significantly proliferation rates of leukemic cells. To test this hypothesis, the investigators will treat 20 CLL patients with an antiviral drug for 3 months in a proof-of-concept clinical trial and leukemic cell counts measured before and after antiviral treatment. Antiviral treatment has the potential to treat the disease at its origin and therefore more efficiently than conventional chemotherapeutic regimens.
This phase II trial studies how well sirolimus, cyclosporine and mycophenolate mofetil works in preventing graft-vs-host disease (GVHD) in patients with blood cancer undergoing donor peripheral blood stem cell (PBSC) transplant. Giving chemotherapy and total-body irradiation before a donor peripheral blood stem cell 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 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. Sometimes the transplanted cells from a donor can make an immune response against the body's normal cells. Giving total-body irradiation together with sirolimus, cyclosporine, and mycophenolate mofetil before and after transplant may stop this from happening.
The goal of this clinical research study is to learn if ofatumumab can help to control CLL/SLL that has not yet been treated. The safety of this drug will also be studied.
This randomized phase III trial studies how well graft-vs-host disease (GVHD) prophylaxis works in treating patients with hematologic malignancies undergoing unrelated donor peripheral blood stem cell transplant. Giving chemotherapy and total-body irradiation before a donor peripheral blood stem cell transplant (PBSCT) 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 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. Sometimes the transplanted cells from a donor can make an immune response against the body's normal cells. Giving total-body irradiation (TBI) together with fludarabine phosphate (FLU), cyclosporine (CSP), mycophenolate mofetil (MMF), or sirolimus before transplant may stop this from happening.
The Chronic Lymphocytic Leukemia (CLL) Research Consortium (CRC) is conducting a two-arm, multi-center phase II trial of Revlimid® and rituximab for Relapsed or Refractory CLL for patients under the age of 65 and patients 65 years and older. Lenalidomide (Revlimid) is an immunomodulatory agent with promising clinical activity in CLL and is FDA approved for treatment of relapsed multiple myeloma and 5q-myelodysplastic syndrome. Rituximab (Rituxan) is a monoclonal antibody to CD20 that is approved for the treatment of CLL. The primary objective of this study is to determine the overall response rate of the combination of Revlimid® and rituximab in previously treated CLL patients. All patients will receive treatment with Revlimid® starting at a low dose that will be dose escalated based on individual patient tolerability. The combination of Revlimid and Rituximab will be administered for a maximum of 7 cycles. Patients with residual leukemia following seven cycles of treatment with the combination may elect to continue on protocol for an additional 6 cycles of single agent Revlimid® consolidation.
