Clinical Trial Summary

The study is designed as a randomized, controlled, open-label, assessor blind, multicenter superiority trial with three parallel groups, and primary endpoint of immunophenotypic complete responses at 18 months after randomization. Block randomization will be performed with a 1:1:1 allocation ratio.

Patients will be randomized up front to 3 arms. Patients will receive "standard" PETHEMA arm for fit elderly VMP x 9 + Rd x 9 (arm 1, control arm), a KRd regimen (arm 2a) (18 cycles) or a Carfilzomib-lenalidomida-dexametasona regimen combined with DARATUMUMAB (arm 2b) (18 cycles).

Description:

After 18 cycles, patients not having received daratumumab before (arm 1 and 2a), will receive consolidation with 4 cycles of Lenalidomida-dexamethasone at low dose-DARATUMUMAB.

At this point (after 22 months on treatment for the VMP-Rd and KRd arm and after 18 months of the Carfilzomib-lenalidomida-dexametasona-DARATUMUMAB arm) patients will be stratified according MRD status by flow and in both MRD- and MRD+ groups, patients will be randomized with a 1:1 allocation ratio to:

1. no further treatment or

2. continuous treatment with DARATUMUMAB-R (daratumumab plus lenalidomide up to 2 years and then lenalidomide continuous until progression).

Patients on no maintenance that show biological relapse will be rechallenged with DARATUMUMAB-R.

The translational part will be very robust with dysplasia monitoring (especially relevant for the Bortezomib-melfalán-prednisona + Lenalidomida-dexamethasone at low dose arm), clonal evolution/resistance follow up and immune reconstitution longitudinal follow up alongside with MRD status (at diagnosis, 9 months, 18 months, 22 months and treatment discontinuation).

The trial is designed as a two-stage study (induction, followed by consolidation and maintenance). The first stage is confirmatory and addresses the primary efficacy objective. The second stage is exploratory and addresses the secondary efficacy and safety objectives.

In the first stage, investigators will compare an optimized standard induction Bortezomib, talidomida and prednisone followed by Rd (18 cycles) versus KRd, that will be tested in this trial with or without daratumumab x 18 cycles. The main objective in this stage will be to compare the immunophenotypic complete response rate assessed by next generation flow at the end of induction.

The second stage is exploratory and includes the consolidation and maintenance phases. In this second stage, the main objectives are:

1. To compare the above mentioned induction strategies in terms of PFS at the end of the different treatment phases (induction, consolidation and maintenance).

2. To investigate the capacity of consolidation with daratumumab-lenalidomide to reduce MRD levels in patients treated in the control arm as well as those that received KRd without daratumumab. In addition we will explore if this short consolidation can abrogate the potential benefit of a prolonged induction with KRd+daratumumab

3. To explore the value of maintenance therapy according to MRD status (positive or negative) to prolong PFS (after a second randomization to receive or not maintenance therapy with lenalidomide and daratumumab) In order to prevent a potential treatment deficiency for patients randomized to "no-maintenance" in both MRD+ and MRD- subgroups, they will be offered to be re-challenged with lenalidomide-daratumumab as soon as they have a biological progression and have been censored for PFS. Moreover, if 30% of the patients randomized to "no-maintenance" relapse or progress during the first year, the protocol will be amended so that all patients receive maintenance therapy.

Investigators consider that the here proposed multidrug sequential "intensive" approach designed to obtain the best possible and most durable response, assessed through the kinetics of MRD clearance, may have an impact in establishing future clinical practice in fit elderly patients. Moreover, in addition to the MRD analysis (based on next generation flow (NGF), NGS and CT-PET) comprehensive biological investigations, including immunoprofile, clonal selection, analysis of dysplastic features and circulating tumor cells, are planned in order to better understand the relationship between patients outcome and myeloma biology.

The overall treatment plan has been designed for NDMM patients not candidates to SCT strategies but fit enough to tolerate a relatively intensive therapeutic strategy. According to the International Myeloma Working Group guidelines as well as the results obtained in our GEM2010 trial for elderly patients, we have decided to restrict this trial to fit elderly patients aged between 65 and 80 years because in our experience patients older than 80 years usually intensive treatments are poorly tolerated [1].

Investigators will evaluate the frailty using a comprehensive health status assessment scale (Geriatric Assessment in Hematology, GAH scale, annex 11), already validated in patients with hematological diseases and preliminary results in multiple myeloma patients

Also males under lenalidomide should commit not to donate semen or sperm during study drug treatment, including during periods of dose interruptions, and for at least 90 days after treatment completion.

NOTE: Given the age of patients to be included on this Clinical Trial (between 65 and 80 years, both included), there is no possibility of Females of Childbearing Potential (FCBP), therefore the Pregnancy Prevention Program (annex 12) has been modified accordingly.
