Pegloticase

Pegloticase (trade name Krystexxa, formerly Puricase) is a drug for the treatment of severe, treatment-refractory, chronic gout, developed by Savient Pharmaceuticals. In September 2010, the FDA approved pegloticase for marketing in the United States after two clinical trials demonstrated the drug lowered uric acid levels and reduced deposits of uric acid crystals in joints and soft tissue. The European Medicines Agency (EMA) granted marketing authorization in January 2013 for treatment of disabling tophaceous gout. Pegloticase is the first and only drug approved for this indication.
