• Patients must have a documented diagnosis of multiple myeloma with evidence of measurable disease i.e. serum M protein superior or equal to 0.5 g per dL measured using serum protein immunoelectrophoresis and or urine M protein superior or equal to 200 mg per 24 hours measured using urine protein immunoelectrophoresis.
• Patients must have received at least 2 prior lines of anti-myeloma therapy, which must include at least 2 consecutive cycles of lenalidomide and a proteasome inhibitor (bortezomib, carfilzomib or ixazomib) given alone or in combination.
• Patients must have failed treatment with lenalidomide and a proteasome inhibitor (bortezomib, carfilzomib, or ixazomib) alone or in combination.
• Patients must have progressed on or within 60 days after end of previous therapy before to study entry, i.e., refractory to the last line of treatment.

Exclusion Criteria:

• Primary refractory multiple myeloma defined as patients who have never achieved at least a minimal response (MR) with any treatment during the disease course.
• Free Light Chain measurable disease only.
• Prior therapy with pomalidomide.
• Any anti-myeloma drug treatment within 14 days before randomization, including dexamethasone.
• Eastern Cooperative Oncology Group performance status superior to 2.
• Platelets inferior to 75 000 cells per µL if inferior to 50% of bone marrow (BM) nucleated cells are plasma cells, and inferior to 30 000 cells per µL if superior or equal to 50% of BM nucleated cells are plasma cells. Platelet transfusion is not allowed within three days before the screening visit.
• Absolute neutrophils count inferior to 1000 per μL (1 x 10E9/L). The use of G-CSF is not allowed to reach this level.

• Aspartate aminotransferase (AST) and/or Alanine Aminotransferase (ALT) superior to 3 x ULN.
• Hypersensitivity to IMiDs (thalidomide or lenalidomide) defined as any hypersensitivity reaction leading to stop IMiDs within the 2 first cycles or toxicity, which does meet intolerance definition.
• Hypersensitivity to dexamethasone, sucrose histidine (as base and hydrochloride salt), and polysorbate 80 or any of the components of study therapy that are not amenable to premedication with steroids, or H2 blockers that would prohibit further treatment with these agents.
• Significant cardiac dysfunction; myocardial infarction within 12 months; unstable, poorly controlled angina pectoris.
• Pregnant or breastfeeding woman or female who intends to become pregnant during the participation in the study.
• Male participants who disagree to practice true abstinence or disagree to use a condom during sexual contact with a pregnant female or a female of childbearing potential while participating in the study, during dose interruptions and at least 3 months following study treatment discontinuation, even if he has undergone a successful vasectomy.
• All patients who disagree to refrain from donating blood while on study treatment and for 4 weeks after discontinuation from this study treatment.
