METHODS: Three phase III randomized, controlled trials compared LEF, MTX, and SSZ in patients with active RA. Improvements in physical function were assessed by Health Assessment Questionnaire Disability Index (HAQ-DI) and Modified Health Assessment Questionnaire (MHAQ); monthly MHAQ and mean HAQ scores were used to calculate American College of Rheumatology responses; HAQ-DI was assessed at baseline and 6-month intervals. In US301, the Medical Outcomes Study 36-Item Short-Form questionnaire (SF-36) assessed treatment-associated changes in HRQOL at baseline and 6-month intervals. RESULTS: Mean and median improvements in HAQ-DI after 12 and 24 months of active treatment in all phase III protocols significantly exceeded -0.22 or a minimum clinically important difference (MCID). These improvements closely reflected positive changes in SF-36 that met or exceeded MCID in all domains with LEF and MTX treatment. Problem Elicitation Technique Top 5 scores reflected improvements in performance of physical activities most important to patients. CONCLUSION: Improvements in physical function were sustained over 24 months of successful treatment with LEF, MTX, and SSZ, and reflected improvements in mental as well as physical domains of HRQOL.
