What was measured

Modified QALYs was calculated from the score of EORTC QLQ-C30. The health-related quality of life scale score of EORTC QLQ-C30 was converted into a utility value ranging from 0 (dead) to 1 (perfect health), and used to adjust the value of survival years; this value was assessed as the modified QALY.

Analysis population: Full Analysis Set (FAS): all participants who were enrolled in Treatment Period I and who receive at least one dose of any therapy during the Treatment Period.

Groups in this outcome

[VRd]; Bortezomib + Lenalidomide + Dexamethasone Therapy

Bortezomib + Lenalidomide + Dexamethasone, standard recommended dose according to the package insert of each drug (Treatment Period I), followed by Ixazomib (4.0 mg) on Days 1, 8 and 15, plus Lenalidomide (25 mg) on Days 1 to 21, and Dexamethasone (40 mg) on Days 1, 8, 15 and 22, of a 28-day cycle (Treatment Period II)
