Open-Label Extension Study for Patients Who Completed a Phase 3 Double-blind Study of PEG-uricase for Symptomatic Gout
28. oktober 2011 opdateret af: Savient Pharmaceuticals
Multicenter, Open Label Extension Study of 8 mg PEG-uricase in Subjects Who Completed Protocols C0405 or C0406 for Symptomatic Gout
This is an open-label extension phase of two double-blind, placebo-controled Phase 3 protocols evaluating PEG-uricase in the treatment of hyperuricemic subjects with symptomatic gout.
The purpose of this study is to provide a continuation of treatment to subjects completing the double-blind studies and obtain long-term safety and efficacy data.

Tophus Response
Tidsramme: 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.

Patient Reported Outcome: SF-36 Physical Component Summary Score
Tidsramme: 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. |

Gout Flare Frequency
Tidsramme: 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
