About this study

Official title: Febuxostat for Tumor Lysis Syndrome Prevention in Hematologic Malignancies: a Randomized, Double Blind, Phase III Study Versus Allopurinol

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

Read the 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.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • FebuxostatDrug

    Also called Adenuric

    Standard dose PO (per os) from Day 1 to Day 7 (can be continued up to DAY 9 at investigator's discretion)

  • AllopurinolDrug

    Also called Zyloric

    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)

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Serum Uric Acid (sUA) Level Control

    Area under the curve of sUA from baseline (Day 1) to the evaluation visit (Day 8)

    Measured: 8 days

  2. Preservation of Renal Function

    Change in serum creatinine level from baseline (Day 1) to the evaluation visit (Day 8)

    Measured: 8 days

Secondary outcomes (3)
  1. Treatment Responder Rate

    Assessment of treatment responder rate, where treatment response is defined as the maintenance of sUA ≤ 7.5 mg/dL from Day 3 to Day 8

    Measured: 6 days

  2. Assessment of Laboratory Tumor Lysis Syndrome (LTLS)

    Assessment of LTLS, from Day 3 to Day 8. According to Cairo-Bishop definition LTLS is defined by the presence of 2 or more laboratory abnormalities including: a 25% increase or levels above normal for serum uric acid, potassium, and phosphate or a 25% decrease or levels below normal for calcium.

    Measured: 6 days

  3. Assessment of Clinical Tumor Lysis Syndrome (CTLS)

    Assessment of CTLS, from Day 3 to Day 8. According to Cairo-Bishop definition, CTLS is defined by the presence of LTLS in addition to 1 or more of the following significant clinical complications: renal insufficiency, cardiac arrhythmias, sudden death and seizures. The grade of CTLS is defined by the maximal grade of the clinical manifestation

    Measured: 6 days

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Febuxostat and Allopurinol in people with Tumor Lysis Syndrome, run by Menarini Group.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 3 Nov 2014. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 3 Nov 2014). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Serum Uric Acid (sUA) Level Control (time frame: 8 days). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT01724528, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 3 Nov 2014.
