  • History of liver disease, as defined by baseline serum transaminase elevation >3X the upper limit of normal in the absence of any other known cause
  • Organ transplant recipient requiring immunosuppressive therapy
  • Concurrent use of prednisone at a dose >10 mg qd (or equivalent) at or within one week before dosing
  • Concurrent use of uric acid-lowering agents
  • Prior treatment with Puricase® or other recombinant uricase
  • An acute gout flare within one week prior to first treatment with Puricase® (exclusive of chronic synovitis/arthritis) requiring use of medication which violates the protocol
  • glucose-6-phosphate dehydrogenase deficiency
  • A history of anaphylactic reaction to a recombinant protein or porcine derivatives
  • Lactation
  • Has taken an investigational drug within 4 weeks prior to study drug administration or plans to take an investigational agent during the study
  • Known allergy to urate oxidase or PEGylated products
  • Has any other medical or psychological condition which, in the opinion of the investigator, might create undue risk to the patient or interfere with the patient's ability to comply with the protocol requirements
