The first poster presents pharmacokinetic and pharmacodynamic data from the 41-patient, 3-month duration, open-label Phase 2 trial of Puricase. The second poster presents an analysis of the application of instruments for measuring health-related quality of life and physical functioning to the assessment of patient-reported outcomes in treatment-failure gout (defined as gout patients for whom allopurinol is contraindicated or is ineffective).

In addition to the two abstracts accepted for poster presentation, two additional abstracts have been accepted for publication on-line. These are:
