[Rasburicase versus allopurinol in the treatment of hyperuricaemia in tumour lysis syndrome] [2010.02]
INTRODUCTION: Hyperuricaemia accompanying tumour lysis syndrome (TLS) is a serious complication in neoplasias with rapid proliferation and cellular destruction. The aim of the study was to evaluate the effects of rasburicase versus allopurinol on plasma uric acid, creatinine and phosphorus levels in paediatric patients with TLS... CONCLUSION: This study demonstrated that there is more rapid control and lower plasma uric acid levels in patients at high risk for tumour lysis syndrome who received rasburicase compared to allopurinol, as well as lower levels of creatinine and a lower percentage of haemodialysis.
A study of rasburicase for the management of hyperuricemia in pediatric patients with newly diagnosed hematologic malignancies at high risk for tumor lysis syndrome. [2009.11]
Tumor lysis syndrome (TLS), including hyperuricemia, is a frequent serious complication in patients with hematologic malignancies. This study in Japanese patients evaluated the efficacy, safety, and pharmacokinetic profile of rasburicase in pediatric patients with hematologic malignancies... Rasburicase is effective and well tolerated for the management of hyperuricemia in Japanese pediatric patients at high risk of developing TLS.
A single dose of rasburicase in elderly patients with hyperuricaemia reduces serum uric acid levels and improves renal function. [2009.04]
AIM: Given the relevance of hyperuricaemia in the development of several diseases, we evaluated rasburicase, generally used in tumor lysis syndrome for uric acid treatment. Our purpose was to evaluate the reduction of serum uric acid and the improvement in renal function... CONCLUSION: In hyperuricaemic elderly patients, a single dose of rasburicase is very effective in lowering serum uric acid levels. Moreover, in patients treated with rasburicase we noted an improvement of renal function. We conclude that rasburicase is an alternative resource for treating those patients who are allopurinol intolerant, have renal dysfunction or have multiple polypharmacy problems in which drug-drug interaction may be of concern.
A randomized comparison between rasburicase and allopurinol in children with lymphoma or leukemia at high risk for tumor lysis. [2001.05.15]
Standard therapy in the United States for malignancy-associated hyperuricemia consists of hydration, alkalinization, and allopurinol... For pediatric patients with advanced stage lymphoma or high tumor burden leukemia, rasburicase is a safe and effective alternative to allopurinol during initial chemotherapy.
A randomized trial of a single-dose rasburicase versus five-daily doses in
patients at risk for tumor lysis syndrome. 
the optimal duration of therapy is unknown in adults... CONCLUSIONS: Rasburicase is highly effective for prevention and management of
Clinical Trials Related to Elitek (Rasburicase)
Rasburicase and Allopurinol in Treating Patients With Hematologic Malignancies [Recruiting]
This randomized phase II trial studies how well giving rasburicase together with allopurinol
works in treating patients with hematologic malignancies. Rasburicase may reduce the level
of uric acid in the blood. Allopurinol may stop the growth of cancer cells by blocking some
of the enzymes needed for cell growth. It is not yet known which dose of rasburicase is more
effective in treating hematologic malignancies when given together with or without
Elitek (Rasburicase) Immuno-Monitoring Study [Recruiting]
To determine the incidence, titer and type of anti-rasburicase antibodies in the context of
hypersensitivity reaction(s) or the loss of uricolytic activity occurring in patients with
relapsed leukemia/lymphoma who have been re-treated with rasburicase and have experienced a
hypersensitivity reaction or loss of uricolytic activity.
Rasburicase as a Uricolytic Therapy for Hyperuricemia in Patients With Leukemia or Lymphoma [Completed]
The primary objectives of the study are to evaluate the safety and the efficacy in patients
with malignant lymphoma or acute leukemia who are repeatedly administered for SR29142 5 days
in two dosage groups.
Secondary objectives are to determine the pharmacokinetic (PK) parameters of SR29142 , to
assess anti-SR29142 antibody production in patients with malignant lymphoma and acute
leukemia, and to estimate the optimal dosage of SR29142 for Japanese patients from the
results of efficacy and safety evaluations.
Rasburicase in Patients at High Risk for Tumor Lysis Syndrome (TLS) During Cycle-2 [Recruiting]
The goal of this clinical research study is to learn if using Elitek (rasburicase) for 2
cycles can help to control or prevent TLS better than 1 cycle of rasburicase and 1 cycle of
allopurinol. The safety of this treatment will also be studied.
Rasburicase for Hyperuricemia [Completed]
Primary: To estimate efficacy of SR29142 to the pediatric patients with newly diagnosed
hematological malignancies at high risk for Tumor Lysis Syndrome, by evaluation of plasma
uric acid concentration.
Secondary: To investigate the safety in this population and anti-SR29142 antibodies, anti-SCP
antibodies, and pharmacokinetic parameters.
