If not stopped, confirm use of current medication and dosage . 24 Pegloticase was approved by the FDA in 2009 for treatment of refractory gout in patients with severe gout intolerant or refractory to allopurinol with SU > 8 mg/dL. Currently, patients with no remaining therapeutic options should simply continue to receive symptomatic treatment of gout attacks. When data in the 2 trials were pooled, the primary end point was achieved in 36 of 85 patients in the biweekly group (42%; 95% CI, 32%-54%), 29 of 84 patients in the monthly group (35%; 95% CI, 24%-46%), and 0 of 43 patients in the placebo group (0%; 95% CI, 0%-8%; P < .001 for each comparison). 2021 Mar 2;23(1):69. doi: 10.1186/s13075-021-02461-7.

Privacy, Help Twelve biweekly intravenous infusions containing either pegloticase 8 mg at each infusion (biweekly treatment group), pegloticase alternating with placebo at successive infusions (monthly treatment group), or placebo (placebo group). Febuxostat had the best efficacy and safety compared to the other drugs. It catalyzes the oxidation of urate to allantoin, thus lowering the SU. 24 The dose approved by the FDA is 8 mg biweekly intravenous infusions. Both patients were intolerant of allopurinol, were not Figure 1. The primary endpoint was the proportion of patients who achieved plasma uric acid less than 6 mg/dL for at least 80% of the time during month 3 and month 6. Serious allergic reactions … Pegloticase … Urate-lowering therapies (aka xanthine oxidase inhibitors) like allopurinol (Zyloprim), febuxostat (Uloric), pegloticase (Krystexxa), and probenecid Uloric and Allopurinol Similarities Uloric and allopurinol both reduce gout flares by decreasing the amount of uric acid in your blood. Background Febuxostat, a novel nonpurine selective inhibitor of xanthine oxidase, is a potential alternative to allopurinol for patients with hyperuricemia and gout. While many patients with gout can be managed with conventional agents (e.g., allopurinol, febuxostat), those with chronic refractory gout often fail to achieve treatment goals with these agents. Unlike uric acid, allantoin is water-soluble and flows easily out of the kidneys. Privacy, Help Pegloticase: a novel agent for treatment-refractory gout. Thrombocytopenia and severe cardiac adverse effects are other probable adverse effects. priate allopurinol dose. Among patients treated with pegloticase in trial C0406, 16 of 42 in the biweekly group (38%; 95% CI, 24%-54%) and 21 of 43 in the monthly group (49%; 95% CI, 33%-65%) achieved the primary end point; no placebo-treated patients reached the primary end point (0/23; 95% CI, 0%-15%; P = .001 and < .001, respectively). J Clin Rheumatol. Some patients are intolerant to or unresponsive to urate-lowering therapies and, therefore, are said to have refractory gout. 1 Although pegloticase lowered serum uric acid level, reduced tophi, and increased patient quality of life, we have concerns about its safety and would like to discuss some cautions.

Serum samples for pegloticase-antibody and pegloticase neutralization assays were obtained before infusions at weeks 1, 3, 5, 9, 13, 17, 21, and 25. They lasted only 6 months and involved 212 patients in whom allopurino/therapy had failed, usually because of serious adverse effects. Of these, 53% of patients receive only 1 pegloticase dose.

This enzyme catabolises uric acid into allantoin, a water-soluble substance that is excreted by the kidneys. Before pegloticase treatment, patients had received allopurinol or febuxostat, but they continued exhibiting symptoms, including visible tophi and serum uric acid (SUA) levels of 5.2–10.2 mg/dL (309–607 μmol/L), despite oral urate-lowering therapy.
