Description:
Background: Systemic AL amyloidosis is a rare disease characterized by amyloid fibril deposits, most commonly in the heart and kidneys; there are currently no health authority-approved treatments. Therapies for the treatment of multiple myeloma (MM), including bortezomib, cyclophosphamide, and dexamethasone (VCd), have been shown to improve outcomes in AL amyloidosis, but more effective therapies are needed to achieve deep and rapid hematologic responses, reverse amyloid-mediated organ dysfunction, and improve overall survival. Daratumumab is an anti-CD38 monoclonal antibody approved as monotherapy or in combination with other agents for the treatment of MM. ANDROMEDA (NCT03201965) is a randomized, open-label, active-controlled phase 3 trial of VCd ± daratumumab subcutaneous (DARA SC) in patients with newly-diagnosed AL amyloidosis. After a median follow-up of 11.4 months, the complete hematologic response rate was 53% for DARA SC + VCd (DARA-VCd) and 18% for VCd (odds ratio, 5.1; 95% CI, 3.2-8.2; P90% at baseline and 〉83% through Cycle 6. Median time to improvement was shorter and median time to worsening was longer in the DARA-VCd group than in the VCd group for EORTC QLQ-C30 GHS and fatigue scales and EQ-5D-5L visual analog scale (VAS) (Table 1). Least squares mean scores for EORTC QLQ-C30 GHS and fatigue, EQ-5D-5L VAS, and SF-36 MCS remained stable in the DARA-VCd group but worsened compared with baseline in the VCd group; between-group differences are shown in Table 2. The greatest between-group differences in PRO score changes from baseline were observed at Week 16 (Cycle 4). After Cycle 6, patients in the DARA-VCd group reported improvements in mean GHS and fatigue scores that continued while on treatment (Figure). Conclusions: Patients with AL amyloidosis treated with DARA-VCd experienced clinical improvements without any decrement in health-related quality of life over 6 cycles. Following Cycle 6, improvements in GHS and fatigue were reported in patients in the DARA-VCd group. These findings further support the value of DARA-VCd in patients with AL amyloidosis.
