Filter by:The rationale for combining lenalidomide with rituximab derives from preclinical observations suggesting that lenalidomide may enhance the ADCC (antigen-dependent cellular cytotoxicity) triggered by monoclonal antibodies such as rituximab. Lenalidomide augments NK cytotoxicity by increasing CD56dimCD3 subset, in addition to inducing IL-2 in T cells. These results provide the cellular and molecular basis for the use of lenalidomide as an adjuvant in immunotherapeutic strategies of monoclonal antibodies (mAb)-based therapies. The combination lenalidomide-rituximab was tested in lymphoma cell lines but not specifically on CLL cell lines. However the observed synergism was attributed to NK cells expansion, thus lending support to the notion that this synergism may operate in other B-cell lymphoproliferative malignancies. The objective was to develop a non-cytotoxic and effective treatment for CLL that would fulfill an unmet medical need, as a significant proportion of CLL patients are elderly and frail. These patients experience an excess in chemotherapy induced toxicity, often preventing the completion of the planned treatment.
Relapse remains a principle cause of treatment failure for patients with aggressive lymphoma after autologous transplantation. Non-myeloablative allogeneic transplantation allows patients to receive an infusion of donor cells in an attempt to induce a graft versus lymphoma effect. This study will assess the feasibility, safety and efficacy of the combination of autologous stem cell transplantation followed by non-myeloablative transplantation for patients with poor-risk aggressive lymphoma.
In this study the investigators investigate a cell therapy strategy that could harness allogeneic effectors that can potentially mediate anti-lymphoma effect. The investigators have designed a novel lymphodepleting conditioning regimen followed by infusion of donor-derived natural killer (NK) cells and interleukin-2 (IL-2) for patients with refractory lymphoid malignancies.
Chronic Lymphocytic Leukemia (CLL) and Small Lymphocytic Lymphoma (SLL) are similar diseases of the white blood cells and are typically treated the same way. Recent research shows that a key enzyme in CLL cells is responsible for cell survival. This enzyme is called LYN kinase. Laboratory studies show that inhibition of LYN kinase in CLL cells results in the death of CLL cells. Dasatinib has the ability to inhibit LYN kinase and, therefore, should have some effect on CLL cells. The purpose of this study is to see of the study drug dasatinib, in combination with fludarabine and rituximab, is safe and effective to use for people with relapsed or refractory CLL/SLL.
This is a unique dose-escalation trial that will titrate doses of umbilical cord blood (UCB) Treg and CD3+ Teff cells with the goal of infusing as many CD3+ Teff cells as possible without conferring grade II-IV acute graft-versus-host disease (GVHD). In this study, the investigators propose to add UCB Treg and UCB CD3+ Teff cells to the two TCD UCB donor units with the goal of transplanting as many CD3+ Teff cells as possible without reintroducing risk of acute GVHD. The investigators hypothesize that Treg will permit the reintroduction of CD3+ Teff cells that will provide a bridge while awaiting HSC T cell recovery long term. The co-infusion of Treg will prevent GVHD without the need for prolonged pharmacologic immunosuppression.
This is an open-label, multi-dose, single-arm, Phase 1, dose-escalation study of XmAb5574. The study was conducted to identify the maximum tolerated dose (MTD) and/or recommended dose(s) (RD) for further study, to characterize safety and tolerability, to characterize PK, PD and immunogenicity, and to evaluate preliminary antitumor activity of XmAb5574 in patients with relapsed or refractory CLL/SLL.
The primary objective of this study is to determine the maximum tolerated dose, dose limiting toxicity, safety and tolerability of TH-302 in patients with acute leukemias, advanced phase chronic myelogenous leukemia (CML), high risk myelodysplastic syndromes, advanced myelofibrosis or relapsed/refractory chronic lymphocytic leukemia (CLL).
This is a phase II, non-randomized, single institution study in symptomatic, previously untreated CLL patients. All patients will receive the study drug, lenalidomide, given PO daily continuously on a 28 day cycle at the starting dose level of either 2.5 mgs or 5 mgs with dose escalations to a target dose of 25mg daily. Oral dexamethasone at 12 mg PO daily will be administered on days 1-7, 14 and 21 of each cycle. Patients will be treated with lenalidomide and dexamethasone to 2 cycles past CR or to a maximum of 18 cycles, each cycle of 28 days duration. Primary endpoint is response.
The investigators' hypothesis is that treatment of CLL with an alternating daily dosing schedule of thalidomide and lenalidomide may result in better tolerability by decreasing each agent's individual toxicities, while preserving efficacy, and therefore lead to a longer duration of therapy and improved responses. Additionally, the combination of the 2 agents may have additive or synergistic effects therapeutically. In Cycle -1, odd numbered patients will receive oral thalidomide daily days 1-14 followed by no treatment on days 15-28. Even numbered patients will receive oral lenalidomide daily on days 1-14 and then no treatment on days 15-28. Starting with cycle 1, patients will alternate daily thalidomide (every odd day) with daily lenalidomide (every even day) for days 1-28. Rituximab will be given on days 1, 8, 15, and 22 starting with Cycle 1, and then again every 6th cycle thereafter (cycles 7, 13, 19, etc.)
The purpose of this research is to evaluate the safety and effectiveness of the drugs lenalidomide and ofatumumab in the treatment of chronic lymphocytic leukemia (CLL).
