Trial summary

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. Read more about this study

About this study

Official title: Efficacy and Safety of Two Comparable Single Low Doses of Rasburicase Followed by Allopurinol in Adult Patients With Malignancy

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 allopurinol.

Read the detailed description

PRIMARY OBJECTIVES:

  1. To prospectively evaluate the efficacy, as defined by uric acid response rate, of 2 different single low doses of rasburicase followed by allopurinol in 2 treatment arms.

SECONDARY OBJECTIVES:

  1. To estimate the proportion of patients requiring additional doses of rasburicase to maintain a uric acid level =< 7.5mg/dL on day 2 through day 6.

II. To identify differential characteristics of the patients who do not respond to treatment.

III. To measure the area under the plasma uric acid concentration-time curve (AUC) from baseline (day 1) to day 7, time to plasma uric acid level less than or equal to 7.5mg/dL.

IV. To evaluate the rate of patients requiring hemodialysis (HD) V. To evaluate the safety of low single-doses of rasburicase. VI. To evaluate the rate of patients expressing a doubling of serum creatinine.

OUTLINE: Patients are randomized to 1 of 2 treatment arms.

ARM I: Patients receive 1.5mg of rasburicase intravenously (IV) over 30 minutes on day 1* and allopurinol orally (PO) once daily (QD) on days 1-6.

ARM II: Patients receive 3 mg of rasburicase IV over 30 minutes on day 1* and allopurinol PO QD on days 1-6.

NOTE: *Patients with serum uric acid >= 7.5mg/dl also receive rasburicase IV on days 2-3.

After completion of study treatment, patients are followed up at 30 days.

What is being measured

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

  1. Probability of Obtaining a Uric Acid Level =< 7.5mg/dL

    The proportion of patients able to achieve and/or maintain a uric acid level =< 7.5mg/dL for each treatment arm.

    Measured: Within 24 hours of rasburicase treatment

Secondary outcomes (5)
  1. Number of Patients Requiring Additional Doses of Rasburicase to Maintain a Uric Acid Level =< 7.5mg/dL

    Count of partcicpants requiring additional doses of rasburicase to maintain a uric acid level =< 7.5mg/dL by treatment arm.

    Measured: Up to day 7

  2. Baseline White Blood Cell Count by Response

    The mean baseline white blood cell count of patients with a complete response (CR) (patients who achieved uric acid level =< 7.5mg/dL) and no CR (patients with uric acid level > 7.5mg/dL).

    Measured: Up to day 7

  3. Area Under the Plasma Uric Acid Concentration-time Curve (AUC) From Baseline (Day 1) to Day 7

    The mean area under the plasma uric acid concentration-time curve (AUC) from baseline (Day 1) to Day 7

    Measured: Up to day 7

  4. Safety of Low Single-doses of Rasburicase.

    The number of patients with any adverse events .

    Measured: up to day 7

  5. Number of Patients Experiencing a Doubling of Serum Creatinine

    Count of participants experiencing a doubling of serum creatinine

    Measured: up to day 6

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing rasburicase and allopurinol in people with Adult Acute Myeloid Leukemia With 11q23 (MLL) Abnormalities and Adult Acute Myeloid Leukemia With Del(5q), run by Roswell Park Cancer Institute at 1 site in United States.

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 9 inclusion and 6 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: stopped early, as of the sponsor's last update on 9 Jan 2018. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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 8 Dec 2017). 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?

Probability of Obtaining a Uric Acid Level =< 7.5mg/dL (time frame: Within 24 hours of rasburicase treatment). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 9 Jan 2018.
