PURPOSE: This analysis evaluated patient-reported outcomes and analgesic use in patients with bone metastases from solid tumours across three comparative studies of denosumab and zoledronic acid.
METHODS: Pooled data were analysed from three identically designed double-blind phase III studies comparing subcutaneous denosumab 120 mg with intravenous zoledronic acid 4 mg monthly in patients with bone metastases from breast cancer (n = 2,046), castration-resistant prostate cancer (n = 1,901) or other solid tumours (n = 1,597). Pain severity, pain interference, health-related quality of life and analgesic use were quantified.
RESULTS: At baseline, approximately half of patients had no/mild pain (53 % [1,386/2,620] denosumab; 50 % [1,297/2,578] zoledronic acid). Denosumab delayed onset of moderate/severe pain by 1.8 months (median, 6.5 vs 4.7 months; hazard ratio, 0.83; 95 % CI, 0.76-0.92; p < 0.001; 17 % risk reduction) and clinically meaningful increases in overall pain interference by 2.6 months (median, 10.3 vs 7.7 months; hazard ratio, 0.83; 95 % CI, 0.75-0.92; p < 0.001; 17 % risk reduction) compared with zoledronic acid. Strong opioid use and worsening of health-related quality of life were less common with denosumab.
CONCLUSIONS: Across three large studies of patients with advanced solid tumours and bone metastases, denosumab prevented progression of pain severity and pain interference more effectively than zoledronic acid.
