Brief summary
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.
Interventions
DRUGBz (Bortezomib)
Bz 1.3 mg/m2 on days +1, +4 and +7. Maintenance therapy and dose reduction pre-specified.
DRUGLen (lenalidomide)
Len at a dose of 6 mg po on day -5 and then 4 mg per day in order to maintain serum levels in the range of 6-12 ng /mL. Maintenance therapy and dose reduction pre-specified.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| 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. | 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. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Incidence of GVHD with this combination (phase I and II) | Up to one year after transplant | Evaluation of a novel combination of Bz plus Len to prevent GVHD after allogeneic transplantation in patients with haematologic malignancies/MM |
| Phase II: response and relapse rate of this approach | Up to one year after transplant | Reduction of relapse rate as defined by the EBMT (European Group for Blood, and Marrow Transplant)criteria. |
| Phase II: safety of the procedure | Up to one year after transplant | For all patients safety will be assessed by the reporting of adverse events starting with the first study-related procedure and up to 30 days after the treatment period. The severity of adverse events will be assessed using National Cancer Institute (NCI) common toxicity criteria (CTC). |
| Evaluate the efficacy on survival | Up to one year after transplant | Evaluate the efficacy of the procedure in terms of event free and overall survival |
| Efficacy of positron emission tomography (PET scan)and local radiotherapy | Up to one year after transplant | Analyze the prognostic value and efficacy of imaging studies using PET scan and local radiotherapy in involved fields prior to or after (\> 100 days) conditioning |
