Criteria
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
International Myeloma Working Group (IMWG) criteria and as decided by an Independent
Review Adjudication Committee (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

- The presence of any of the following will exclude a subject from enrollment:

1. Subjects with multiple myeloma who were not treated as a part of Study
CC-4047-MM-003 (Arm B).

2. Subjects who received any anti-myeloma or anti-cancer therapies 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);

- Hemoglobin < 8 g/dL (< 4.9 mmol/L; prior RBC transfusion or recombinant
human erythropoietin use is permitted)

- Serum SGOT/AST or SGPT/ALT > 3.0 x upper limit of normal (ULN)

- 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 Multiple Myeloma (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).

8. Peripheral neuropathy ≥ Grade 2.

9. Subjects who received an allogeneic bone marrow or allogeneic peripheral blood
stem cell transplant less than 12 months prior to initiation of study treatment
and who have not discontinued immunosuppressive treatment for at least 4 weeks
prior to initiation of study treatment and are currently dependent on such
treatment.

10. Subjects who are planning for or who are eligible for stem cell transplant.

11. Subjects with any one of the following:

- Congestive heart failure (NY Heart Association Class III or IV)

- Myocardial infarction within 12 months prior to starting study treatment

- Unstable or poorly controlled angina pectoris, including Prinzmetal variant
angina pectoris

12. Subjects who received any of the following within the last 14 days of initiation
of study treatment:

- Plasmapheresis

- Major surgery (kyphoplasty is not considered major surgery)

- Radiation therapy

13. Use of any investigational agents within 28 days 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.

16. Incidence of gastrointestinal disease that may significantly alter the absorption
of pomalidomide.

18. Any serious medical condition, laboratory abnormality, or psychiatric illness
that would prevent the subject from signing the informed consent form.
