At the time of analysis, 10 patients had completed treatment, three had discontinued the study, two had met the serum urate monitoring rules at two consecutive visits but had discontinued pegloticase, and five patients continued to receive pegloticase therapy. At week 24, no notable changes to eGFR were identified. Also at week 24, in the 10 patients who had completed pegloticase treatment, HAQ-pain and HAQ-DI scores improved by 26.7±30.3 (baseline: 35.9±30.2) and 0.2±0.5 (baseline: 1.0±1.0), respectively.

Seven serious adverse events occurred in five individuals. These reactions included atrial fibrillation, cellulitis (N=2), diverticulitis, duodenal ulcer, localized infection and sepsis. These reactions were deemed unrelated to pegloticase administration. No anaphylaxis or infusion reactions occurred.
The use of pegloticase in kidney transplant recipients to reduce serum uric acid levels without affecting renal function is beneficial. The preliminary data presented herein show promising results in these patients, who often have high levels of serum uric acid and symptomatic gout despite prior treatment with uric acid-lowering agents, either due to intolerance or ineffectiveness.
