What is being measured

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

  1. Description of the pharmacokinetic (PK) profile for naloxegol in terms of maximum observed plasma concentration (Cmax) and area under the plasma concentration-time curve from time zero extrapolated to infinity (AUC) for each treatment period.

    Measured: Predose,0.25, 0.5, 1, 1.5, 2, 3, 4, 5, 6, 8, 12, 16, 24, 36, and 48 hours

Secondary outcomes (5)
  1. Description of the safety profile in terms of adverse events, clinical laboratory assessments , vital signs (blood pressure and pulse rate), physical examinations, electrocardiograms, and Columbia-Suicide Severity Rating scale (CSSRS)

    Measured: From baseline day 1 through to Follow-up (Maximum 40 days)

  2. Description of the pharmacokinetic(PK) profile for naloxegol in terms of time to Cmax (tmax), terminal half-life (t1/2λz), terminal rate constant (λz). For each treatment period

    Measured: Predose,0.25, 0.5, 1, 1.5, 2, 3, 4, 5, 6, 8, 12, 16, 24, 36, and 48 hours

  3. Description of the pharmacokinetic (PK) profile for naloxegol in terms of area under the plasma concentration-time curve from time zero to the time of the last quantifiable concentration [AUC(0-t)].For each treatment period

    Measured: Predose,0.25, 0.5, 1, 1.5, 2, 3, 4, 5, 6, 8, 12, 16, 24, 36, and 48 hours

  4. Description of the pharmacokinetic (PK) profile for naloxegol in terms of area under the plasma concentration-time curve from time zero to 24 hours [AUC(0-24)], apparent oral clearance from plasma (CL/F).For each treatment period

    Measured: Predose,0.25, 0.5, 1, 1.5, 2, 3, 4, 5, 6, 8, 12, 16, 24, 36, and 48 hours

  5. Description of the pharmacokinetic (PK) profile for naloxegol in terms of apparent volume of distribution during the terminal phase (Vz/F)For each treatment period

    Measured: Predose,0.25, 0.5, 1, 1.5, 2, 3, 4, 5, 6, 8, 12, 16, 24, 36, and 48 hours

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Naloxegol in people with Opioid Induced Constipation, run by AstraZeneca 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 4 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: finished, as of the sponsor's last update on 15 Oct 2014. 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?

Description of the pharmacokinetic (PK) profile for naloxegol in terms of maximum observed plasma concentration (Cmax) and area under the plasma concentration-time curve from time zero extrapolated to infinity (AUC) for each treatment period. (time frame: Predose,0.25, 0.5, 1, 1.5, 2, 3, 4, 5, 6, 8, 12, 16, 24, 36, and 48 hours). 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 15 Oct 2014.
