简要总结
The aim of the current study is to improve the outcome of patients with hematologic malignancies (in a phase I trial) and more specifically multiple myeloma (in a phase II trial) by 2 interventions: reduce the risk of graft-versus-host disease (GVHD) and improve the efficacy of the procedure decreasing the risk of relapses after transplant.
Currently, the standard approach used in most centers to prevent graft-versus-host disease after allogeneic transplantation is based on the combination of a calcineurin inhibitor (cyclosporine or tacrolimus) plus a short course of methotrexate. Unfortunately, this strategy is far from ideal, since the risk of acute GVHD is in the range of 30-40% among patients receiving a matched related donor transplantation and even higher among patients receiving transplantation from an unrelated donor while the incidence of chronic GVHD is 60-70% among patients receiving peripheral blood progenitor cells from either a related or unrelated donor.
As far as the patients with multiple myeloma (MM) is concerned, although the development of new drugs has markedly changed the outcome and management of these patients, allogeneic transplantation so far appears to be the only curative option, especially among those patients relapsing after first line treatment. Nevertheless, still new strategies within the allogeneic transplant setting are needed to improve its results.
Relapses may occur either extramedullary (very common in this setting) or systemic. In order to reduce the risk of systemic relapses the investigators will use maintenance therapy with Lenalidomide (Len) which, together with bortezomib (Bz) should contribute to eradicate minimal residual disease (MRD). In case the patient do not obtain complete remission or near complete remission after transplant, in addition to the maintenance therapy, the investigators will use four intensification cycles with VRD (Bz-Len-Dexamethasone).
In summary, the goal is to optimize the efficacy of allogeneic transplantation by two interventions: one focused on reducing the risk of relapse and the other on reducing the incidence of GVHD.

结局指标
主要结局
Phase I trial: Safety of Len + Bz in patients with hematologic malignancies Phase II trial: Safety and efficacy of an optimized strategy of allogeneic transplantation in multiple myeloma undergoing allogeneic transplantation.
时间窗: Up to one year after transplant
For phase I trial: safety of Len + Bz. The phase I trial safety criteria will be evaluated in terms of (1) engraftment defined as \> 500 granulocytes / microL and \> 20.000 platelets / microL x 3 consecutive days will be required for 9/10 patients, (2) incidence of neuropathy grades 3-4 attributed to Bz \> 20% (3) incidence of gastrointestinal toxicity attributed to Bz \> 20%. For phase II trial: safety evaluated through adverse events and toxicity and efficacy evaluated as reduction of relapse rate as defined by the EBMT criteria.
