About this study

Official title: A Cohort Dose-Escalation Phase 1 Study of Intramuscular Injection of Uricase-PEG 20

The purpose of this study is to assess the safety, pharmacokinetics and pharmacodynamics of single and multiple intramuscular doses of Uricase-PEG 20

Read the detailed description

Uricase is an enzyme (found in most mammals but not humans) that converts poorly soluble uric acid into highly soluble allantoin. Because humans lack uricase, they are prone to develop elevated levels of uric acid, which can form crystals in the joints and soft tissues. In those which chronically elevated uric acid, gout may develop. In the setting of acute rises in uric acid, seen for example in tumor lysis syndrome, uric acid crystals can damage the renal tubules. Uricase-PEG 20 is a recombinant uricase conjugated with multiple PEG molecules designed to prolong the half-life and decrease the immunogenicity of uricase. This study will characterize the safety, pharmacokinetics and pharmacodynamics of intramuscular Uricase-PEG 20, the anticipated route of administration to be used in future clinical development in gout.

Receives: Biological: Uricase-PEG 20

What is being measured

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

  1. Safety (assessment of signs and symptoms and clinical laboratory measurements following administration of Uricase-PEG 20, graded according to the Common Toxicity Criteria for Rheumatology, version 2.0)

    Measured: Up to 35 days after dosing

Secondary outcomes (3)
  1. Pharmacokinetics (Uricase-PEG 20 serum concentration)

    Measured: Up to 35 days after dosing

  2. Pharmacodynamics (plasma uric acid concentration)

    Measured: Up to 35 days after dosing

  3. Immunogenicity

    Measured: Up to 35 days after dosing

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Uricase-PEG 20 in people with Gout and Hyperuricemia, run by EnzymeRx at 2 sites 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 3 inclusion and 4 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: status not confirmed, as of the sponsor's last update on 24 Dec 2009. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites 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 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

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

Are results available for this study?

Results are not available in the source record.

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

Contact Rocelle Flores (201-843-4424 ext. 203, rflores@enzymerx.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Safety (assessment of signs and symptoms and clinical laboratory measurements following administration of Uricase-PEG 20, graded according to the Common Toxicity Criteria for Rheumatology, version 2.0) (time frame: Up to 35 days after dosing). 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 NCT01038947, 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 24 Dec 2009.
