Brief Summary:

This trial will evaluate the efficacy and safety of combination of pomalidomide (POM) and low-dose dexamethasone (LD-Dex) (Cohort A) or the combination of pomalidomide (POM) , daratumumab (DARA) and low-dose dexamethasone (LD-Dex) (Cohort B) in subjects with relapsed or refractory multiple myeloma who have received a first or second line treatment of lenalidomide-based therapy.

This trial will test the hypothesis for Cohort A that the proportion of patients will have an Overall Response Rate (ORR) of > 30 % to reveal that Pomalidomide is efficacious in pretreated patients who are refractory to lenalidomide.

This trial will test the hypothesis for Cohort B that the proportion of patients will have an Overall Response Rate (ORR) of > 70 % to reveal that POM+DARA+LD-Dex is efficacious in pretreated patients who are refractory to lenalidomide.

This trial will test the hypothesis for Cohort C that the proportion of patients will have an Overall Response Rate (ORR) of >60% to reveal that POM+DARA+LD-Dex is efficacious in pretreated patients who are refractory to lenalidomide. This treatment will be in only Japanese patients.

Primary Outcome Measures :
  1. Overall response rate (ORR) [ Time Frame: Approximately 2 years ]
    The primary endpoint will be the Overall Response Rate (ORR) by modified International Myeloma Working Group (mIMWG) criteria and will be based on the best response prior to the time frame. ORR will consist of the responses of PR or better (Complete Response -CR, Very Good Partial Response-VGPR or Partial Response- PR).


Secondary Outcome Measures :
  1. Overall survival (OS) [ Time Frame: Up to 7 years ]
    Overall survival will be calculated as the time from start of treatment until the time of death from any cause. If no death is recorded the subject will be censored at the time the subject was last known to be alive.

  2. Progression-free survival (PFS) [ Time Frame: Up to 7 years ]
    Progression-free survival will be calculated as the time from start of treatment until the time of PD (as determined by the site Investigator based on the mIMWG criteria) or death from any cause on study treatment, whichever comes first. Subjects not experiencing a documented progression will be censored at the time of their last response assessment (or at the time of trial enrollment if no assessment was conducted).

  3. Duration of Response (DoR) [ Time Frame: Up to 7 years ]
    Duration of response, calculated for responders only, is defined as time from the initial documented response (PR or better) to the first confirmed PD or until death from any cause. Subjects without a documented progression will be censored at the time of their last response assessment

  4. Time to Response (TTR) [ Time Frame: Up to 2 years ]
    Time to response, calculated for responders only, is calculated as the time from the start of treatment to the first documented response (PR or better) based on modified International Working Group ( mIMWG) criteria.

  5. Time to progression (TTP) [ Time Frame: 6 months after 100% enrollment and 5 years from Last Patient First Visit ]
    Time to progression will be calculated as the time from start of treatment until PD (as determined by the site Investigator based on the mIMWG criteria) or death from progressive disease. Subjects not experiencing a documented progression will be censored at the time of their last response assessment (or at the time of trial enrollment if no assessment was conducted).

  6. Adverse Events [ Time Frame: Up to 7 years ]
    Number of participants with adverse events including secondary primary malignancies.
