Health-Related Quality of Life of Patients with Newly Diagnosed Multiple Myeloma Receiving Lenalidomide Maintenance: Data from the Connect MM Disease Registry

Conference Correspondent - Conference Correspondent, ASH 2016 - Multiple Myeloma

Maintenance therapy after autologous stem-cell transplant (ASCT) has demonstrated extended time to progression and progression-free survival for patients with multiple myeloma (MM). However, maintenance treatment until progression has the potential to adversely impact health-related quality of life (HRQoL). Using data from the Connect MM registry, Abonour and colleagues evaluated HRQoL of patients based on maintenance treatment status.

Patients ≥18 years who completed induction therapy and first-line ASCT who may or may not have gone on to receive maintenance were included in the analysis. Patients were evaluated in 3 groups: (1) Any maintenance (including lenalidomide [LEN]-only), (2) LEN-only maintenance, and (3) No maintenance.

Patient-reported HRQoL data were collected at protocol-defined quarterly visits, using the EQ-5D Index score. Secondary measures included the Functional Assessment of Cancer Therapy–Multiple Myeloma (FACT-MM) total score and the Brief Pain Inventory (BPI). HRQoL assessments were analyzed at study entry (study baseline); after induction therapy but prior to ASCT; and quarterly from 100 days post-ASCT until the end of maintenance or until progressive disease, discontinuation, or death.

Of the 540 patients who received ASCT, 238 (44%) met the analysis criteria for Any maintenance, 167 (31%) for LEN-only, and 138 (26%) for No maintenance. A higher proportion of patients in the Any and LEN-only maintenance groups received triplet therapy as induction versus the No maintenance group (64%, 66%, and 51%, respectively). The median number of EQ-5D forms completed per patient and the mean baseline HRQoL scores for each measure were comparable across the 3 groups. Researchers found no significant differences in estimated mean post-ASCT scores when comparing Any or LEN-only with the No maintenance group for the EQ-5D Overall Index, the FACT-MM Total Score, or the BPI.

Given that HRQoL scores were similar across the 3 groups for the 3 measures studied, the authors concluded that patient quality of life is not substantially impacted by maintenance therapy despite the inherent risks associated with continued active therapy.
