Starting on completion of Cycle 2, response was assessed according to IMWG criteria based on Investigator's assessment for all patients at every cycle during treatment period. VGPR was defined as serum and urine M-protein detectable by immunofixation but not on electrophoresis or ≥90% reduction in serum plus urine M-protein level \\<100 mg/24hr and \\>90% decrease in difference between involved and uninvolved free light chain (FLC) levels (only in FLC diseased patients). CR was defined as negative immunofixation on serum and urine, loss of any soft tissue plasmacytomas, \\<5% plasma cells in bone marrow and normal FLC ratio of 0.26 to 1.65 (only in FLC diseased patients). sCR was defined as CR plus normal FLC ratio and absence of clonal cells in bone marrow by immunohistochemistry or 2 to 4 color flow cytometry.","dispersionType":"95% Confidence Interval","groups":[{"description":"Patients were treated with 15 mg melflufen as IV infusion on Day 1 and 40 mg dexamethasone oral tablet or IV infusion on Days 1, 8 and 15 of each 21-day treatment cycle.
