Abstract

Patient-reported outcomes in AL amyloidosis have not been well-studied. We analyzed health-related quality of life (HRQOL) and AL amyloidosis symptoms data from the phase 3 TOURMALINE-AL1 trial (NCT01659658) (ixazomib-dexamethasone, n = 85; physician's choice of chemotherapy [PC], n = 83). HRQOL and symptom burden were measured with the SF-36v2, Functional Assessment of Cancer Therapy/Gynecologic Oncology Group Neurotoxicity subscale (FACT/GOG-Ntx), and an amyloidosis symptom questionnaire (ASQ). Score changes during treatment were analyzed descriptively and using repeated-measures linear mixed models; analyses were not adjusted for multiplicity. Least-squares (LS) mean changes from baseline were significantly higher (better HRQOL) for ixazomib-dexamethasone at several cycles for SF-36v2 Role Physical and Vitality subscales (p <.05); no subscales demonstrated significant differences favoring PC. For FACT/GOG-Ntx, small but significant differences in LS mean changes favored ixazomib-dexamethasone over PC at multiple cycles for seven items and both summary scores; significant differences favored PC for one item (trouble hearing) at multiple cycles. ASQ total score trended downward (lower burden) in both arms; significant LS mean differences favored ixazomib-dexamethasone over PC at some cycles (p <.05). Patients with relapsed/refractory AL amyloidosis treated with ixazomib-dexamethasone experienced HRQOL and symptoms that were similar to or trended better than patients treated with PC despite longer duration of therapy.
