JAMA. Real-world patterns of pegloticase use for treatment of gout: descriptive multidatabase cohort study. National Library of Medicine [FIGURES 2 & 3] Conclusion: After pegloticase discontinuation, most patients quickly initiated allopurinol. 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. Arthritis Rheum. Unlike uric acid, allantoin is water-soluble and flows easily out of the kidneys. Conventional urate-lowering drugs available in the U.S. are allopurinol, febuxostat and probenecid. Allopurinol and its metabolite oxipurinol both act as xanthine oxidase inhibitors thereby they decrease uric acid levels in the body. To systematically review the evidence on the efficacy, safety, and cost-effectiveness of urate-lowering therapy for gout: xanthine oxidase inhibitors (allopurinol and febuxostat), uricosuric medications (benzbromarone, probenecid and sulfinpyrazone), and uricases (pegloticase and rasburicase). clinicaltrials.gov Identifier: NCT00325195.

Febuxostat had the best efficacy and safety compared to the other drugs. Probenecid is a better choice when allopurinol is ineffective or poorly tolerated. COVID-19 is an emerging, rapidly evolving situation. Drugs. Strand V, Khanna D, Singh JA, Forsythe A, Edwards NL. In total, 338 patients received pegloticase, prescribed by approximately 150 unique clinicians. KRYSTEXXA (pegloticase) is a prescription medicine for adults who have tried other gout medicines and still have high uric acid and gout symptoms. Two or more sUA results post-pegloticase were provided for 6/23 patients that did not initiate ULT within 180 days; 5/6 (83%) had 2+ sUA ≥6 mg/dL. It catalyzes the oxidation of urate to allantoin, thus lowering the SU.

In trial C0405 the primary end point was reached in 20 of 43 patients in the biweekly group (47%; 95% CI, 31%-62%), 8 of 41 patients in the monthly group (20%; 95% CI, 9%-35%), and in 0 patients treated with placebo (0/20; 95% CI, 0%-17%; P < .001 and <.04 for comparisons between biweekly and monthly groups vs placebo, respectively). Please enable it to take advantage of the complete set of features! Pegloticase was studied in replicate phase III double-blinded randomized placebo controlled trials (RCTs) enrolling 212 patients with refractory gout (defined as sUA > 8 mg/dl, plus either: three or more flares in the previous 18 months; at least one tophus lesion; or chronic gouty arthropathy, despite allopurinol use or in the setting of allopurinol intolerance). Pegloticase has been granted EU marketing authorisation in patients who continue to have severe gout attacks despite treatment with a xanthine oxidase inhibitor such as allopurinol. Sundy JS, Becker MA, Baraf HS, Barkhuizen A, Moreland LW, Huang W, Waltrip RW 2nd, Maroli AN, Horowitz Z; Pegloticase Phase 2 Study Investigators.
