What was measured

Myeloma response was defined as a best overall response of complete response (CR) or partial response (PR) CR is defined as: - Absence of original monoclonal paraprotein in serum and urine by immunofixation maintained at least 42 days. - \<5% plasma cell in bone marrow aspirate and on bone marrow biopsy, if performed. - No increase in size or number of lytic bone lesions. - Disappearance of soft tissue plasmacytomas. PR requires all of the following: - ≥ 50% reduction in level of serum monoclonal paraprotein, maintained at least 42 days. - Reduction in 24-hour urinary light chain extraction by ≥ 90% or to \< 200 mg, maintained at least 42 days. - For patients with non-secretory myeloma, ≥ 50% reduction in plasma cells in bone marrow aspirate and on biopsy, if performed, for at least 42 days. - ≥ 50% reduction in the size of soft tissue plasmacytomas. - No increase in size or number of lytic bone lesions.

Analysis population: Efficacy Evaluable Population includes all participants who met eligibility criteria, took at least one dose of study medication, and had a baseline and a post-baseline efficacy assessment.

Groups in this outcome

Pomalidomide Plus Dexamethasone

Participants received 4 mg pomalidomide administered by mouth on Days 1-21 of each 28-day treatment cycle and 40 mg dexamethasone (participants \> 75 years of age received 20 mg dexamethasone) administered by mouth once per day on Days 1, 8, 15, and 22 of a 28-day cycle until disease progression.

Group identifiers and denominators belong to this outcome only. They may differ in another outcome or in safety reporting.
