Tophus Response
Délai: Up to 2 years
|
Target tophi evaluated during the randomized, controlled study were followed for response at 3, 6, 12, 18 and 24 months in this open-label extention study.
Results from each participant's final assessment on drug are reported (as last observation carried forward).
Complete response=complete disappearance of at least one tophus with no new or worsening tophus.
Partial Response=a 50% or more decrease in at least one tophus with no new or worsening tophus.
|
Up to 2 years

Patient Reported Outcome: SF-36 Physical Component Summary Score
Délai: RCT Week 25; OLE Week 25; OLE Week 53, OLE Week 77, OLE Week 101
|
SF-36 is the Medical Outcomes Survey Short Form-36, a 36-item self-reported questionnaire which assesses health-related limitations in 8 dimensions. The Physical Component Summary Score (PCS) is a composite summary score derived from the dimensions related to physical functioning outcomes: Physical Function, Role Physical, General Health and Bodily Pain (each with a 0 to 100 scale where 0=worst, 100=best). The Summary Score is constructed as a T-score with a mean of 50 and standard deviation of 10, where higher scores indicate a better health status. |
