| Main Objective: To determine MTD of Carfilzomib Weekly based on definition of DLTs ;Secondary Objective: • To determine the VGPR (Very Good Partial Response) + CR (complete response) rate of Carfilzomib weekly at the MTD + MP at the end of the 9 induction cycles • To determine the safety profile of Carfilzomib weekly +MP for the first 9 cycles and during maintenance. • To determine the safety profile of Carfilzomib Weekly according to doses in the first part of the study • To determine the response rate (Partial response and better), the stringent CR rate (sCR) and Immunophenotypic CR (MRD; Will be performed by in Nantes, France) during the first 9 cycles and during maintenance. • To determine the clinical benefit response rate (CBR, Minor response and better). • To determine the Progression-free Survival (PFS), Event-free Survival (EFS), and Time to Progression (TTP) • To determine the Overall Survival • To determine the Time to response and Response duration ;Primary end point(s): To determine MTD of Carfilzomib Weekly. If dose-limiting toxicities (DLTs) occur in fewer than 3 of these patients per cohort, the next cohort of 6 patients (cohort 2, 3 and 4) will be N+1 up to cohort 4. If at any time during cycle 1 of a dose cohort, > 2 subjects experience a drug-related DLT, the MTD will have been exceeded, additional enrolment within the cohort will cease, and dose escalation will stop. The MTD will be defined as the dose level below which DLT is observed in >33% (i.e. > 2 of 6) subjects in a cohort. ;Timepoint(s) of evaluation of this end point: At the end of the study when the last patient will have relapsed | — |

| Secondary end point(s): •To determine the VGPR (Very Good Partial Response) + CR (Complete Response) rate of Carfilzomib Weekly at the MTD + MP at the end of the 9 induction cycles using International Myeloma Working Group (IMWG) response criteria •To determine the Safety profile (type, frequency, severity, and relationship of adverse events to study treatment). Incidence of Treatment Emergent Adverse Event (TEAE), Serious Adverse Events (SAE) and laboratory abnormalities using National Cancer Institute (NCI) common toxicity criteria for the first 9 cycles and during maintenance. • To determine the safety profile of Carfilzomib Weekly according to doses in the first part of the study • To determine the Overall Response rate [Partial (PR) and better] using IMWG response criteria and to determine the sCR rate using IMWG response criteria (12) during the first 9 cycles and during maintenance. • Minor response will be determined using EBMT criteria • To determine the Progression-free Survival (PFS, from the date of inclusion to the date of the progression); Event-free Survival (EFS, from the date of inclusion to the date of any event, progression, death or any other cause for end of treatment); Time to progression (TTP, from the date of inclusion to the date of the progression or death, whichever occurs first); Overall Survival (OS, from the date of inclusion to the date of the last news); • To determine the Time to response (TTR, from the date of inclusion to the date of the first observation of response) and Response duration (DOR, time between first documentation of response and disease progression) ;Timepoint(s) of evaluation of this end point: At the end of the study when the last patient will have relapsed | — |
