Study groups in NCT00401583
Study groupRoleWhat they receive
Pazopanib receiversExperimentalDuring Days 1 and 2 subjects will be dosed with only probe drugs, and with no drugs on Days 3-5. During Days 6 to the end of the study, subjects will receive 800 mg daily pazopanib, and on Days 23-24 subjects will receive probe drugs in addition to pazopanib
Receives: Drug: GW786034 (pazopanib); Drug: Probe drugs

What is being measured

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

  1. To investigate the potential of GW786034 to inhibit or induce various CYP450 enzymes.

    Measured: throughout the study

Secondary outcomes (1)
  1. Safety of co-administration of 800 mg daily GW786034 and CYP450 probe drugs. To describe GW786034 steady-state pharmacokinetics on this once daily dosing regimen.

    Measured: throughout the study

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 4 inclusion and 10 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

The record says: finished, as of the sponsor's last update on 13 Nov 2017. 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, Singapore. 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?

To investigate the potential of GW786034 to inhibit or induce various CYP450 enzymes. (time frame: throughout the study). 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 NCT00401583, 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?
