Official Title: “A Randomized, Multicenter, Open-Label, Comparison of Rasburicase (Fasturtec) Versus Allopurinol for the Prophylaxis and Treatment of Hyperuricemia in Chinese Patients With Leukaemia or Lymphoma”

Primary:

To compare the efficacy of Rasburicase versus allopurinol in controlling tumor lysis-related hyperuricemia in Chinese patients with leukemia or lymphoma.

Secondary:

To compare the efficacy and safety of Rasburicase versus allopurinol in Chinese patients stratified according to disease (leukemia or lymphoma ).
