About this study

Official title: In Vitro-In Vivo Relationship Study to Assess the Impact of the In Vitro Dissolution Profile on the Pharmacokinetic Parameters Used to Establish Bioequivalence

The purpose of this study is to determine whether defined and limited changes in in vitro dissolution impact the in vivo pharmacokinetics (PK) and relative bioavailability of allopurinol and the active metabolite oxypurinol.

Read the detailed description

In this study, a single oral dose of Zyloprim® (300 mg tablet) and 3 separate single oral doses of 300 mg allopurinol test formulations (Regimens B, C and D) will be administered sequentially to each subject on separate occasions. Following the administration of Regimens B and C, there will be a period of interim analysis during which the PK data will be reviewed to determine the formulation within the process design space that provides the desired in vitro dissolution variant for dosing in the subsequent study period.

What is being measured

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

  1. PK profile of Zyloprim® and three dissolution test formulations of allopurinol from plasma

    PK endpoints in terms of maximum observed concentration (Cmax), time of occurrence of maximum observed concentration (Tmax), area under the concentration-time curve (AUClast), area under the concentration-time curve (AUC∞) and apparent terminal half-life (t1/2)

    Measured: Predose (within 30 minutes before dosing), 15, 30, and 45 minutes postdose, and 1, 1.5, 2, 3, 4, 6, 8, 10, 12, 18, 24, 36, 48, 72, and 96 hours postdose.

Secondary outcomes (1)
  1. Incidence of Adverse Events

    Changes in Laboratory, Electrocardiogram and Vital Signs Parameters

    Measured: 11 weeks

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Zyloprim® 300 mg, Allopurinol 300 mg; undergranulated, high hardness condition and Allopurinol 300 mg; alternative condition 2 in people with Healthy, run by Ardea Biosciences, Inc. at 1 site in United Kingdom.

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 2 inclusion and 16 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 1 Jan 2016. 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 Kingdom. 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?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

PK profile of Zyloprim® and three dissolution test formulations of allopurinol from plasma (time frame: Predose (within 30 minutes before dosing), 15, 30, and 45 minutes postdose, and 1, 1.5, 2, 3, 4, 6, 8, 10, 12, 18, 24, 36, 48, 72, and 96 hours postdose.). 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 1 Jan 2016.
