Rasburicase

0.15mg/kg intravenously over 30 minutes once per day for 5 consecutive days.

Saroj Vadhan-Raj, M.D.

Primary

1. To determine the pharmacokinetic (PK) parameters of rasburicase in adult patients with leukemia and/or lymphoma at high risk or potential risk of tumor lysis syndrome (TLS)

Secondary

1. To evaluate plasma uric acid AUC from baseline (within 4 hours prior to first rasburicase treatment) through 48 hours after the last per-protocol planned administration of rasburicase treatment;
2. To evaluate the safety of rasburicase in adult patients with leukemia and/or lymphoma.
3. To evaluate incidence, duration, and type of immune responses (IgG, IgE, and neutralizing antibody) to rasburicase.

Rasburicase is designed to help decrease or prevent the high level of uric acid that may occur during the start of chemotherapy. A high level of uric acid may lead to reduced kidney function or kidney failure.

TLS occurs when high uric acid levels are caused by breakdown of tumor cells after the start of chemotherapy. The dead tumor cells can release uric acid and other symptoms of kidney failure, such as excessive amounts of potassium and phosphorus, into the blood.

Before you can start treatment on this study, you will have "screening tests." These tests will help the doctor decide if you are eligible to take part in this study. Your complete medical history will be recorded, and you will have a physical exam, including measurement of your vital signs (blood pressure, heart rate, temperature, and breathing rate), height, and weight. You will have blood drawn (about 2 tablespoons) for routine tests. Women who are able to have children must have a negative blood (a sample will be used from the routine blood draw) or urine pregnancy test.

If you are found to be eligible to take part in this study, you will receive rasburicase by a needle in your vein over 30 minutes once a day for 5 days in a row. You will receive chemotherapy within 4-24 hours after your first dose of rasburicase.

On Days 1-5 (study drug treatment period), you will have a physical exam, including measurement of your vital signs. During this time, you will have blood drawn (about 2 tablespoons each) once a day for routine tests.

You will have blood drawn (less than 1 teaspoon each) for PK testing at different time points throughout this study. PK tests measure the level of the study drug in the blood at different times. You will have a total of 14 samples drawn. Your blood will be drawn on Day 1 before your dose of rasburicase and then at 30 minutes and at 4, 8, 24, 48, 72, 96, 96.5,100,104,120 (Day 6),168 (Day 8), and 336 (Day 15) hours after your dose of the study drug.

You will have blood drawn (less than 1 teaspoon each) to measure the level of uric acid in your blood at different time points throughout this study so that researchers can learn the effectiveness of the study drug on your disease. You will have a total of 7 samples drawn. Your blood will be drawn on Day 1 before your dose of rasburicase and then at 4, 24, 48, 72, 96,120 (Day 6), and 144 (Day 7) hours after your dose of the study drug.

You will also have blood drawn (less than 1 teaspoon each) for antibody testing at different time points throughout this study. Antibody testing is a method to check for proteins (IgG) made by your body that show that your body is reacting to rasburicase. You will have at least 5 samples drawn. Your blood will be drawn on Day 1 before your dose of rasburicase and then on Day 14, Day 35, and at 3 and 6 months after your dose of the study drug.

If you have a positive IgG (antibody protein) at the 6-month blood draw for antibody testing, you will continue to have blood drawn (less than 1 teaspoon) every 6 months until your antibody protein is negative.

If you experience any side effects related to allergic reactions during treatment with the study drug (up to 30 days after your last dose of the study drug), you will have an additional blood draw (less than 1 teaspoon) for antibody testing within 48 hours after having the reaction.

You will be taken off this study if your disease gets worse or you experience any intolerable side effects.

You will have assessments after the end of your study drug treatment (from Days 1 to 5). These assessments will include a physical exam, including measurement of your vital signs, on Days 14 and 35. You will also have blood drawn (about 2 tablespoons each) for routine tests on Days 8 and 14.

This is an investigational study. Rasburicase is authorized by the FDA for use (in adults) in research only. Rasburicase will be provided free of charge during this study. Up to 20 patients will take part in this multicenter study. Up to 20 can be enrolled at M. D. Anderson.
