The first pegloticase infusion defined the index date. Based on concomitant immunomodulatory drug treatment, we identified three exposure groups: (1) immunomodulatory drug initiators (patients initiating an immunomodulatory prescription \u00b160 days from the index date), (2) prevalent immunomodulatory drug recipients (patients receiving their first immunomodulatory drug prescription &gt;60 days before the index date with at least one prescription within \u00b160 days of the index date), and (3) immunomodulatory nonrecipients (patients receiving pegloticase without concomitant immunomodulatory drugs). We calculated the proportion of patients who achieved serum urate levels \u22646 mg\/dL and who had laboratory abnormalities (white blood cell count &lt;3.4 x 10<jats:sup>9<\/jats:sup>\/L, platelet count &lt;135,000, hematocrit level &lt;30%, alanine aminotransferase or aspartate aminotransferase level \u22651.5 times the upper limit normal value) within 180 days after the index date.

Immunomodulatory drug recipients were less likely to discontinue pegloticase. The adjusted hazard ratios of pegloticase discontinuation associated with concomitant immunomodulatory drug initiation and prevalent treatment were 0.52 (95% confidence interval [CI] 0.37\u20130.75) and 0.69 (95% CI 0.42\u20131.16), respectively.
