Brief Summary:
This is a single-center single-arm phase 2 study in which patients will receive daratumumab in combination with clarithromycin/pomalidomide/dexamethasone (D-ClaPd) until progressive disease (PD) or unacceptable toxicity, whichever comes first. This study will test the hypothesis that in patients with previous daratumumab exposure, combination therapy of clarithromycin/pomalidomide/dexamethasone (ClaPd) will yield higher Very Good Partial Response (VGPR) rates in relapsed/refractory multiple myeloma patients than historical pomalidomide/dexamethasone treatment.

Primary Outcome Measures :
  1. Best response rate within 8 cycles of induction therapy [ Time Frame: Approximately 3 years ]
    Best response rate defined as the proportion of participants with a documented response of partial response (PR) or better, per International Myeloma Working Group (IMWG) criteria measured from date of enrollment until end date of the 8th cycle of induction therapy.


Secondary Outcome Measures :
  1. Median estimate of months that participants have progression free survival [ Time Frame: Approximately 5 years ]
    Median estimate calculated using the Kaplan-Meier methodology

  2. Median number of months of participant's overall survival [ Time Frame: Approximately 8 years ]
    Overall survival (OS) is measured from the date of enrollment to the date of the participant's death. Greenwood's formula will be used to calculate 95% confidence intervals for the Kaplan-Meier survival estimates

  3. Time to Complete Hematologic Response [ Time Frame: Approximately 3 years ]
    Measured in months between the date of enrollment and the first efficacy evaluation at which the participant has met the criteria for hematologic complete response.

  4. Time to Hematologic progression [ Time Frame: Approximately 3 years ]
    Measured in months between the date of enrollment and the first efficacy evaluation at which the participant has met the criteria for hematologic progression

  5. Duration of hematologic response [ Time Frame: Approximately 3 years ]
    Duration of hematologic response is defined as the time between the date of initial documentation of hematologic response to the date of first documented evidence of hematologic progressive disease.

  6. Time until next treatment therapy [ Time Frame: Approximately 5 years ]
    Measured in months from the date of enrollment to the start date of subsequent treatment for relapsed/refractory multiple myeloma

  7. Time to complete response (CR) [ Time Frame: Approximately 3 years ]
    Measured in months between the date of enrollment and the first efficacy evaluation at which the participant has met the criteria for CR

  8. Duration of Very Good Partial Response (VGPR) [ Time Frame: Approximately 3 years ]
    Duration of hematologic VGPR is defined as the time between the date of initial documentation of hematologic VGPR to the date of first documented evidence of hematologic progressive disease

  9. Rate of minimal residual disease (MRD) negativity after 8 months [ Time Frame: Approximately 3 years ]
    Defined as a percentage of MRD-negative participants from date enrollment until 8 months after start of treatment.

  10. Rate of minimal residual disease (MRD) negativity after 32 months [ Time Frame: Approximately 3 years ]
    Defined as a percentage of MRD-negative participants from date enrollment until 32 months after start of treatment.

  11. Rate of improvement in response during maintenance therapy [ Time Frame: Approximately 3 years ]
    Defined as percentage of patients that achieved a better response rate per International Myeloma Working Group (IMWG) criteria from initial documentation of response on date of enrollment
