Keywords: Febuxostat, Tumor lysis syndrome, leukemia, lymphoma
Allocation: RANDOMIZED | Intervention model: PARALLEL
Enrollment: 346
Healthy volunteers: no

Brief summary:
The purpose of this study is to determine whether febuxostat is superior to allopurinol in the prevention of tumor lysis syndrome (TLS) in patients with hematological malignancies at intermediate or high risk of TLS (according to Cairo-Bishop classification) who undergo chemotherapy

Detailed description:
This study is designed as a randomised, double-blind, active-controlled, parallel-group study to be conducted in approximately 80 sites.

Approximately 340 male or female patients aged 18 or older suffering from hematologic malignancies (de novo patients or relapsing patients) at intermediate to high risk of TLS and scheduled for receiving the first cycle of cytotoxic chemotherapy, regardless of the line of treatment, will be randomized in this study. Eligible patients (as per screening visit) will be randomly allocated in a 1:1 ratio to Febuxostat or Allopurinol. The double-blind treatment period starts two days prior to the planned beginning of chemotherapy and continues for 7 to 9 consecutive days, according to Investigator judgment and on the basis of the actual duration of chemotherapy regimen administered to the patient. Along the study treatment, uric acid levels, creatinine levels, Laboratory TLS/Clinical TLS and Adverse Events represent the major clinical findings to be monitored on a daily basis. Overall the study encompasses 10 to 11 planned visits at site, including screening, randomisation, on treatment and final follow up visits.

Arms:
arm 1: Febuxostat for 7-9 days arm 2: Allopurinol for 7-9 days

Interventions: intervention 1: Febuxostat intervention 2: Allopurinol
Intervention descriptions: intervention 1: Standard dose PO (per os) from Day 1 to Day 7 (can be continued up to DAY 9 at investigator's discretion) intervention 2: Standard dose, low dose or high dose (as per investigator's judgement at the time of randomization) from DAY 1 to DAY 7 (can be continued up to DAY 9 at investigator's discretion)
