Main objective

Scope: Therapy, Safety

The primary objective of the study is to evaluate the rate of patients achieving very good partial response (VGPR) or better to the oral combination Iberdomide, Ixazomib, Dexamethasone.

Secondary objectives 9

1. To evaluate safety and tolerability of Iberdomide Ixazomib and Dexamethasone. To evaluate the safety and efficacy of Iberdomide plus Ixazomib (Cycle 7 and more).
2. To evaluate Overall Survival (OS), Progression free survival (PFS), time to progression (TTP), duration of response (DOR), duration of therapy (DOT), time to response (TTR)
3. To evaluate Overall Response Rate (ORR)
4. To evaluate ORR, PFS, TTP and OS in patients previously exposed to lenalidomide
5. To evaluate ORR, TTP, PFS and OS in patients refractory to lenalidomide
6. To evaluate biological prognosis factors influencing outcome and response
7. To evaluate the impact of frailty scores (IMWG, IFM) on PFS and OS
8. To assess Quality of Life (QoL)
9. To evaluate molecular and immune profile of this population of patients with relapsed myeloma previously exposed to lenalidomide with or without anti-CD38 monoclonal antibody. Bone marrow aspirate will be performed at baseline to support translational research project including: plasma cell profiling (cereblon, CD38, CD55, CD59 expression), immunoprofiling (T-cell (CD4, CD8) and NK-cell phenotype)

9. 9. Patient should comply with Celgene’s pregnancy prevention plan for Iberdomide (please see appendix 8 Iberdomide Pregnancy Prevention Plan for subjects in clinical trials)
10. 10. Female patients who: - are postmenopausal for at least 24 months before the screnning visit, OR - are surgically sterile (have undergone a hysterectomy or bilateral oophorectomy)
11. Men even if surgically sterilized must agree to not father a child and agree to practice complete abstinence or to use a condom during therapy and dose interruptions and for 90 days after the last dose of study drug, even if they have had a successful vasectomy, if their partner is of childbearing potential or pregnant.

Secondary endpoints 10

1. Number of adverse events defined by Common Terminology Criteria for Adverse Events (v5)
2. ORR including Partial Response (PR), Very Good Partial Response (VGPR), Complete Response (CR) and minor response (MR) to Iberdomide Ixazomib and Dexamethasone will be evaluated according to IMWG criteria at 3 months and 6 months of treatment
3. Time to progression (TTP) is defined as the time in months from inclusion to the date of disease progression or death due to any cause. Subject alive or lost to follow-up without experiencing documented disease progression will be censored at the date of last valid disease and response assessment.
4. Time to response (TTR) is defined as the time from inclusion to the date of the first response (PR or better)
5. Duration of Response (DOR) is defined as the time from the first response (PR or better) to the date of disease progression or death due to any cause. Subject alive or lost to follow-up without experiencing documented disease progression will be censored at the date of last valid disease and response assessment.
6. Duration of therapy (DOT) is defined as the time from treatment initiation to the last dose of therapy
7. Fragilty scores (IMWG, IFM Kumar Lancet Oncol 2016) will be assessed at time of inclusion
8. Overall Survival (OS) is defined as the time in months from inclusion to the date of death due to any cause. Subject alive will be censored at the last known alive date.
9. Value of biological prognostic factors as ISS stage, cytogenetic as del(17p), t(4;14), t(14;16), t(14;20), amp(1q) and del(1p) will be explored. Bone marrow aspirate will be performed at baseline to support translational research project including: plasma cell profiling (cereblon, CD38, CD55, CD59 expression), immunoprofiling (T-cell (CD4, CD8) and NK-cell phenotype)
10. Quality of life (EQ5D and SF36 scales will be used to assess QOL)
