The randomized pivotal phase III FIRST trial (Frontline Investigation of lenalidomide/dexamethasone [Rev/Dex] versus Standard Thalidomide; IFM 2007-01/ MM-020; clinicaltrials.gov identifier: 00689936; EudraCT No. 2007-004823-39) compared the efficacy and safety of Rd, administered continuously until progressive disease (PD) or for a fixed 18-month duration (Rd18), with MPT given for 18 months in NDMM patients who were aged 65 years or over, or who were aged under 65 years and ineligible for stem cell transplantation. Continuous Rd showed improved progression-free survival (PFS) and overall survival (OS) benefit at interim analysis compared with MPT. 19 Although extending survival is clearly the ultimate treatment ©2015 Ferrata Storti Foundation.

Manuscript accepted on March 6, 2015 We compared the health-related quality-of-life of patients with newly diagnosed multiple myeloma aged over 65 years or transplant-ineligible in the pivotal, phase III FIRST trial. Patients received: i) continuous lenalidomide and low-dose dexamethasone until disease progression; ii) fixed cycles of lenalidomide and low-dose dexamethasone for 18 months; or iii) fixed cycles of melphalan, prednisone, thalidomide for 18 months. Data were collected using the validated questionnaires (QLQ-MY20, QLQ-C30, and EQ-5D). The analysis focused on the EQ-5D utility value and six domains pre-selected for their perceived clinical relevance. Lenalidomide and low-dose dexamethasone, and melphalan, prednisone, thalidomide improved patients' health-related quality-of-life from baseline over the duration of the study across all pre-selected domains of the QLQ-C30 and EQ-5D. In the QLQ-MY20, lenalidomide and low-dose dexamethasone demonstrated a significantly greater reduction in the Disease Symptoms domain compared with melphalan, prednisone, thalidomide at Month 3, and significantly lower scores for QLQ-MY20 Side Effects of Treatment at all post-baseline assessments except Month 18. Linear mixed-model repeatedmeasures analyses confirmed the results observed in the cross-sectional analysis. Continuous lenalidomide and low-dose dexamethasone delays disease progression versus melphalan, prednisone, thalidomide and has been associated with a clinically meaningful improvement in health-related quality-of-life. These results further establish continuous lenalidomide and low-dose dexamethasone as a new standard of care for initial therapy of myeloma by demonstrating superior health-related quality-of-life during treatment, compared with melphalan, prednisone, thalidomide.Health-related quality-of-life in patients with newly diagnosed multiple myeloma in the FIRST trial: lenalidomide plus low-dose dexamethasone versus melphalan, prednisone, thalidomide [20][21][22][23] In this population, treatment objectives should be to improve disease management by delaying disease progression, optimizing re...
