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.
||Observational Model: Cohort
Time Perspective: Prospective
||A Multicenter Registry Study of Anti-rasburicase Antibodies in Patients Retreated With Rasburicase (SR29142) in the Context of Relapsing Leukemia/Lymphoma Who Experienced Subsequent Hypersensitivity Reaction(s) or Loss of Uricolytic Activity: An Immuno-Monitoring Observational Study
Primary Outcome Measures:
- Prevalence/frequency of presence of anti-rasburicase antibodies in eligible population. [ Time Frame: Day 1, i.e. within 48 hours of identification /diagnosis of HSR (hypersensitivity reaction) or loss of uricolytic activity ] [ Designated as safety issue: No ]
- Titer/type of anti-rasburicase antibodies in eligible population. [ Time Frame: Day 1, i.e. within 48 hours of identification /diagnosis of HSR (hypersensitivity reaction) or loss of uricolytic activity ] [ Designated as safety issue: No ]

Patients are selected as the clinical manifestations for study inclusion (hypersensitivity reaction or the loss of uricolytic activity) are recognized during clinically-indicated re-challenge with rasburicase.
Previous history of rasburicase exposure and history of administration of a repeat (2nd) series of rasburicase injections (in the context of supportive care for relapsing leukemia/lymphoma) and subsequent development of either a hypersensitivity reaction (HSR) or loss of uricolytic activity (defined as failure to achieve uric acid level of < or = 7.5 mg/dl measured 48 hours after the first rasburicase injection).
A severe hypersensitivity reaction (NCI Grade 3, 4 or 5) is defined as:
Allergic reaction; allergy; anaphylactic shock; bronchospasm; bullous skin eruption; dermatitis - exfoliative; drug hypersensitivity; dyspnea; hypotension; hypoxia; rash; rash - erythematous; rash - maculopapular, urticaria; pyrexia/fever; edema; chest discomfort; hypersensitivity (NOS); pharynx discomfort; hoarseness; pharyngeal erythema; pruritus; erythema; localized exfoliation; rash - papular; swelling ¿ face/facial; toxic skin eruption; hot flush; flushing; rash - macular; rash - pruritic; pruritus - allergic.
Loss of uricolytic activity can be defined as:
- uric acid levels > 7.5 mg/dl measured 48 hours after the first rasburicase injection¿, which is a time point coincident with administration of the third dose of rasburicase (within that second course of treatment with this agent).
- Patients should have received at least 2 doses of rasburicase during the repeat (2nd) administration in the event of loss or uricolytic activity. At least 1 dose of rasburicase should be administered during the repeat (2nd) administration for diagnosis of HSR.
- Concomitant treatment with human IV immunoglobulin (IVIG)
- Concomitant treatment with TNF-alpha antagonists/inhibitors, i.e. adalimumab, infliximab, and etanercept
- Concomitant treatment with Interferon-alpha (IFN-alpha)
- Unwillingness or inability to comply with the requirements of the protocol.
