BACKGROUND: Chronic osteoarthritis (OA) pain impacts health-related quality of life (HR-QOL).
OBJECTIVE: The primary aim of this study was to evaluate and compare HR-QOL outcomes following treatment with once-daily push-pull Osmotic controlled-Release Oral delivery System (OROS) hydromorphone versus twice-daily extended-release (ER) oxycodone for moderate to severe chronic knee or hip OA pain.
METHODS: This was a 6-week, randomized, open-label, parallel-group, multicenter study of 124 patients with OA whose pre-trial treatment included NSAIDs or other non-steroidal, non-opioid analgesics. The HR-QOL of patients was assessed using the Medical Outcomes Study (MOS) Sleep Scale and the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC™). Within- and between-group changes from baseline to 6 weeks were evaluated using ANOVA.
RESULTS: At baseline, trial patients had significantly worse MOS Sleep Scale (multivariate ANOVA [MANOVA] F = 11.0, p < 0.001) and WOMAC™ scores (MANOVA F = 55.7, p < 0.001) than chronic disease benchmarks. Both treatment groups showed significant improvements on the sleep disturbance scale (p < 0.01), with additional improvements observed with OROS hydromorphone on the sleep quantity (p = 0.046), sleep snoring (p = 0.044), awaken short of breath or with a headache (p = 0.024), 6-item sleep problems index I (p < 0.001), and 9-item sleep problems index II (p < 0.001) scales. Significant treatment differences in favor of OROS hydromorphone over ER oxycodone were also observed on the awaken short of breath or with a headache (p = 0.014) scale and sleep problems index I (p = 0.045). Both treatment groups showed comparable large effect size (>0.8 SD unit) improvements on the WOMAC™ scale (measuring functionality outcomes such as pain, stiffness, physical function etc).
CONCLUSION: Both OROS hydromorphone and ER oxycodone improved sleep and function, with greater sleep benefits being observed in patients treated with OROS hydromorphone.
