Carfilzomib in Treatment Patients Under 65 Years With High Risk Smoldering Multiple Myeloma

Smoldering Multiple Myeloma Clinical Trial

Official title: A Phase II Multicenter Study of Carfilzomib, Lenalidomide and Dexamethasone (KRd) as Induction Therapy, Followed by High-dose Therapy With Melphalan and Autologous Peripheral Blood Stem Cell Transplantation, Consolidation With KRd, and Maintenance With Lenalidomide and Dexamethasone in Patients ≤ 70 Years Old With Smoldering Multiple Myeloma (SMM) With High Risk of Progression to Symptomatic Myeloma

Status Active, not recruiting

Clinical Trial Summary

Patients included in the study will receive induction treatment during 6 months, followed by receive high-dose therapy followed by peripheral blood stem cell transplantation.

Approximately 3 months after peripheral blood stem cell transplantation patients will receive consolidation treatment during 2 months.

Subsequently patients will start maintenance treatment during 24 months. Therefore, the total duration of the treatment will be approximately 36 months.

Clinical Trial Description

This clinical trial is a multicenter Phase II study designed to evaluate the efficacy and toxicity of an intensive therapeutic approach in 90 patients with asymptomatic high risk multiple myeloma (SMM).

1. - Patients will receive an induction treatment consisting of 6 cycles of carfilzomib, lenalidomide and low-dose dexamethasone (KRd): patients will receive carfilzomib 20-36 mg/m2 IV on days 1, 2, 8, 9, 15 and 16; with oral lenalidomide 25 mg daily on days 1-21, subsequently there will be a rest period of a week (from day 22 to day 27). Moreover, oral dexamethasone 40mg daily will be administered weekly (days 1, 8, 15 and 22).

2. - Following the induction treatment, patients will receive high-dose (200 mg/m2) melphalan-based treatment administered via the intravenous route followed by peripheral blood stem cell transplantation (HDT-ASCT).

3. - The consolidation treatment will consist of 2 cycles of KRd, with the same doses and scheduled of the induction treatment.

4. - Maintenance treatment: all patients, without progression to symptomatic multiple myeloma or toxicity requiring discontinuation of the trial, will receive maintenance treatment during 24 cycles.

This maintenance treatment comprises the administration of lenalidomide 10mg on days 1-21, followed by a rest period of 1 week, with the weekly administration of dexamethasone 20mg.

Treatment will be administrated until the end of the maintenance, although patients will continue in the trial.

If biological progression is observed following the discontinuation of the treatment, lenalidomide and dexamethasone will be reinstituted in order to control the disease again. Lenalidomide 10 mg will be administrated on days 1-21 combined with dexamethasone 20mg on days 1, 8, 15 and 22. All patients will be monitored for asymptomatic disease progression and to collect data regarding on overall survival (OS). ;
