Filter by:This is a multicenter open-label uncontrolled phase II study. There are no previous clinical data to estimate the expected response rate of everolimus in MALT lymphomas and in the other less common MZLs (i.e. nodal and splenic) refractory or relapsing after at least 1 prior systemic treatment (chemotherapy or immunotherapy). The primary objective of this study is to define the antitumor activity, in term of overall response rate (ORR), as sum of complete remissions (CR) and partial remissions (PR) of everolimus in relapsed or refractory marginal zone B-cell lymphomas. The secondary objectives of this study are to assess safety, as acute or long-term toxicity, response duration (RD) (time to relapse or progression) in responders and progression-free survival (PFS) (time to disease progression or death from any cause) in all patients.
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.
Pre-clinical data and recently published clinical data suggest a synergistic effect between lenalidomide and dexamethasone. We hypothesize that a combination of lenalidomide-dexamethasone can overcome rituximab resistance. To determine the response rate to lenalidomide and dexamethasone plus rituximab therapy in subjects with recurrent small B-cell non-Hodgkin lymphoma who have had lymphoma progression within 6 months of being treated with rituximab alone or with a rituximab-containing regimen, we propose initial treatment with both drugs for two 28-day treatment cycles (Part I). After response assessment following two cycles of lenalidomide-dexamethasone, patients will enter Part II of the study. In Part II, patients will receive lenalidomide-dexamethasone and rituximab to evaluate the potential reversal of rituximab resistance as measured by response to rituximab and progression-free survival following rituximab.
