Inclusion Criteria

1. Subjects with refractory or relapsed and refractory multiple myeloma who were enrolled in Study CC-4047-MM-003 and discontinued study therapy with dexamethasone alone (Treatment Arm B) after at least starting the second cycle of dexamethasone treatment and due to development of documented disease progression according to the IMWG criteria and as decided by an IRAC.
2. Must be = 18 years at the time of signing the informed consent form.
3. The subject must understand and voluntarily sign an informed consent document prior to any study related assessments/procedures being conducted. The only exception is if a skeletal survey was performed within 90 days prior to the start of Cycle 1, then a new survey will not be required.
4. Must be able to adhere to the study visit schedule and other protocol requirements.
5. Subjects must have documented diagnosis of multiple myeloma and have measurable disease (serum M-protein = 0.5g/dL or urine M-protein = 200 mg/24 hours).
6. Eastern Cooperative Oncology Group (ECOG) performance status score of 0, 1, or 2.
7. Females of childbearing potential (FCBP†) must agree to utilize two
reliable forms of contraception simultaneously or practice true abstinence [when this is in line with the preferred and usual lifestyle of the subject. Periodic abstinence (e.g., calendar, ovulation, symptothermal, post ovulation methods) and withdrawal are not acceptable methods of contraception]from heterosexual contact for at least 28 days before starting study drug, while participating in the study (including dose interruptions), and for at least 28 days after study
treatment discontinuation and must agree to regular pregnancy testing during this timeframe.
8. Females must agree to abstain from breastfeeding during study participation and 28 days after study discontinuation.
9. Males must agree to either use a latex condom during any sexual contact with FCBP or practice true abstinence [when this is in line with the preferred and usual lifestyle of the subject. Periodic abstinence (e.g. calendar, ovulation, symptothermal, post-ovulation methods) and withdrawal are not acceptable methods of contraception] while
participating in the study and for 28 days following discontinuation from this study, even if he has undergone a successful vasectomy.
10.Males must also agree to refrain from donating semen or sperm while on pomalidomide and for 28 days after discontinuation from this study treatment.
11. All subjects must agree to refrain from donating blood while on study drug and for 28 days after discontinuation from this study treatment.
12. All subjects must agree not to share study medication.

Exclusion Criteria

1.Subjects with multiple myeloma who were not treated as a part of Study CC-4047-MM-003 (Arm B).
2.Subjects who received anti-myeloma, or anti-cancer therapy within the last 14 days of wash-out period before initiation of study treatment.
3.Subjects who discontinued CC-4047-MM-003 study =120 days.
4.Subjects who initiate another anti-myeloma therapy from the time of disease progression on study CC-4047-MM-003 to the time of treatment initiation in the companion study.
5.Any of the following laboratory abnormalities:
• Absolute neutrophil count (ANC) < 1,000/µL.
• Platelet count < 75,000/µL for subjects in whom < 50% of bone marrow nucleated cells are plasma cells; or a platelet count < 30,000/µL for subjects in whom = 50% of bone marrow nucleated cells are plasma cells
• Creatinine Clearance < 45 mL/min according to Cockcroft-Gault formula (if creatinine clearance calculated from the 24-hour urine sample is >=45 mL/min, patient will qualify for the trial)
• Corrected serum calcium > 14 mg/dL (> 3.5 mmol/L); or free ionized calcium > 6.5 mg/dL (> 1.6 mmol/L)
• Hemoglobin < 8 g/dL (< 4.9 mmol/L; prior RBC transfusion or recombinant human erythropoietin use is permitted)

• Serum total bilirubin > 2.0 mg/dL (34.2 µmol/L); or > 3.0 x ULN for subjects with hereditary benign hyperbilirubinaemia
6.Prior history of malignancies, other than MM, unless the subject has been free of the disease for = 5 years. Exceptions include the following:
• Basal or Squamous cell carcinoma of the skin
• Carcinoma in situ of the cervix or breast
• Incidental histologic finding of prostate cancer (TNM stage of T1a or T1b)
7.Hypersensitivity to thalidomide or lenalidomide. (This includes =Grade 3 rash during prior thalidomide or lenalidomide therapy).

13. Use of any investigational agents within 28days or 5 half lives (whichever is longer) of treatment.
14. Subjects with chronic conditions such as rheumatoid arthritis, multiple sclerosis and lupus, which likely need additional steroid or immunosuppressive treatments in addition to the study treatment.
15. Any condition including the presence of laboratory abnormalities, which places the subject at unacceptable risk if he/she were to participate in the study.

Primary Outcome Measures
NameTimeMethod
Primary end point(s): The primary endpoint is overall response rate (ORR) using the new International Myeloma Working Group Uniform (IMWG) response criteria. An analysis comparing the results of response assessments judged by the EMBT criteria (Blade, 1998) to those of the IMWG criteria will also be performed.;Timepoint(s) of evaluation of this end point: Time to event;Main Objective: To evaluate the efficacy of pomalidomide (CC-4047) monotherapy in subjects with refractory or relapsed and refractory multiple myeloma who discontinued from Treatment Arm B (dexamethasone alone) of Study CC-4047-MM-003 due to the development of documented disease progression during treatment.;Secondary Objective: To evaluate the safety of pomalidomide monotherapy in subjects with refractory or relapsed and refractory multiple myeloma who discontinued treatment after being treated in the dexamethasone alone arm (Treatment Arm B) in Study CC-4047-MM-003 due to the development of documented disease progression during treatment.
