Misure di risultato primarie
Misura del risultato |
Misura Descrizione |
Lasso di tempo |
|---|---|---|
|
Uric Acid (mg/dL)
Lasso di tempo: Week 13, Week 25, Week 53, Week 101

|
Week 13, Week 25, Week 53, Week 101
|
Misure di risultato secondarie
Misura del risultato |
Misura Descrizione |
Lasso di tempo |
|---|---|---|
|
Tophus Response
Lasso di tempo: 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
Lasso di tempo: 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. |
RCT Week 25; OLE Week 25; OLE Week 53, OLE Week 77, OLE Week 101
|
|
Gout Flare Frequency
Lasso di tempo: Up to 2 years
|
The the mean number of flares per subject (flare frequency)was assessed over 3-month periods for up to 2 years of treatment
|
Up to 2 years
|
|
Gout Flare Incidence
Lasso di tempo: Assessed in 3-month intervals up to 2 years
|
Percentage of participants remaining in the study during the specified interval who experienced a gout flare during this interval.
|
Assessed in 3-month intervals up to 2 years
