| Summary: | Abstract Objective Gout is a progressive form of arthritis that causes significant pain and disability. Patients with treatment-refractory (or uncontrolled) gout experience a higher prevalence and severity of comorbidities than those whose gout is controlled. Pegloticase is a recombinant PEGylated uricase indicated for the treatment of gout in patients refractory to conventional therapy. We evaluated the treatment journey of patients with chronic uncontrolled gout before initiation of pegloticase therapy. Methods Using IQVIA’s PharMetrics® Plus database, we conducted a retrospective observational analysis of adults with ≥ 1 pegloticase claim between April 1, 2011, and August 31, 2020. Demographics were assessed at baseline. Clinical outcomes, health care resource utilization (HCRU), and associated costs were compared over two 12-month periods (months 13–24 and 1–12) prior to the first pegloticase claim (index date). Results The study included 408 patients. Prevalence of all gout-associated conditions increased between months 1–12 and 13–24 (P < 0.05 for all). The percentage of patients with tophi increased from 15.4% to 61.5%, the percentage with ≥ 1 flare increased from 49% to 84%, and mean number of flares per patient increased from 1.0 to 2.1 (P < 0.0001 for all). The frequency of all categories of HCRU except emergency department visits also increased (P < 0.0001 for all), as did gout-related healthcare utilization (P£0.005). Conclusions Patients with uncontrolled gout experienced an increase in the clinical burden of disease and HCRU in the 2 years before the initiation of pegloticase. Earlier patient identification and initiation of potentially effective therapy may help alleviate these burdens. |
