Summary:

      The primary purpose of the study is to evaluate the safety and efficacy and to generate PK
      and biomarker data for the combination of pomalidomide and low-dose dexamethasone in patients
      with refractory or relapsed and refractory multiple myeloma.

      The study consists of a Screening phase within 28 days prior to cycle 1 day 1, a Treatment
      phase and a Follow-up phase which starts within 28 days of discontinuation from study
      treatment, every 3 months for up to 5 years.

      In addition, the collection of steady-state PK data from a large population will enable
      robust population PK and assess Pomalidomide exposure response analyses.

      The exploratory objectives of the study are to investigate potential markers predictive of
      POM response or resistance and pharmacodynamic markers.
