Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 18 to 55 years
  • Men only
  • Healthy volunteers accepted
  • Adult

Who may be able to join

  • Healthy male subjects between the ages of 18 and 55 years (inclusive):Healthy is defined as no clinically relevant abnormalities identified by a detailed medical history, full physical examination, including blood pressure and pulse rate measurement, 12-lead ECG and clinical laboratory tests.
  • Body Mass Index (BMI) of 17.5 to 30.5 kg/m2; and a total body weight >50 kg (110 lbs).
  • An informed consent document signed and dated by the subject.
  • Subjects who are willing and able to comply with scheduled visits, treatment plan, laboratory tests, and other study procedures.

Who cannot join

  • Evidence or history of clinically significant hematological, renal, endocrine, pulmonary, gastrointestinal, cardiovascular, hepatic, psychiatric, neurologic, or allergic disease (including drug allergies, but excluding untreated, asymptomatic, seasonal allergies at time of dosing).
  • Subjects enrolled in a previous radionucleotide study or who have received radiotherapy within 12 months prior to screening or such that total radioactivity would exceed acceptable dosimetry.
  • A positive urine drug screen or urine cotinine test
  • 12 lead ECG demonstrating QTc >450 or a QRS interval >120 msec msec at Screening. If QTc exceeds 450 msec, or QRS exceeds 120 msec, the ECG should be repeated two more times and the average of the three QTc values should be used to determine the subject's eligibility. Subjects with family history of myocardial infarction, congenital long QT syndrome, torsades de pointes or clinically significant ventricular arrhythmias. Subjects should be within normal range of potassium, magnesium and calcium at screening.

About this study

Official title: A Phase One Open-Label Single-Radiolabeled Dose Study To Investigate The Absorption, Metabolism, And Excretion Of [14C] PF-04449913 In Healthy Male Volunteers

The study aims to understand, using radiolabelled PF-04449913, how this compound is modified by the body once it is absorbed. The study also aims to understand how much of the compound is broken down and how much leaves the body unchanged.

What is being measured

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

  1. Area Under the Curve From Time Zero to Extrapolated Infinite Time [AUC (0 - 8)]

    AUC (0 - 8)= Area under the plasma concentration versus time curve (AUC) from time zero (pre-dose) to extrapolated infinite time (0 - 8). It is obtained from AUC (0 - t) plus AUC (t - 8).

    Measured: 7 days

  2. Maximum Observed Plasma Concentration (Cmax)

    Measured: 7 days

  3. Area Under the Curve From Time Zero to Extrapolated Infinite Time [AUC (0 - 8)] for total radioactivity related to drug product

    AUC (0 - 8)= Area under the plasma radioactivity concentration versus time curve (AUC) from time zero (pre-dose) to extrapolated infinite time (0 - 8). It is obtained from AUC (0 - t) plus AUC (t - 8).

    Measured: 7 days

  4. Maximum Observed Plasma Concentration (Cmax) for total radioactivity related to drug product

    Measured: 7 days

  5. Cumulative recovery of radioactivity in excreta

    Total percentage of dosed radioactivity recovered in urine and feces

    Measured: 7 days

  6. Radioactivity in blood

    Total percentage of radioactivity in blood related to drug product

    Measured: 7 days

  7. Urine PF-04449913 PK parameters

    Measure of renal clearance (CLr), amount excreted unchanged in urine (Ae) and the fraction of dose excreted unchanged in urine (AE%)

    Measured: 7 days

Secondary outcomes (4)
  1. Area Under the Curve From Time Zero to Last Quantifiable Concentration (AUClast)

    Area under the plasma concentration time-curve from zero to the last measured concentration (AUClast)

    Measured: 7 days

  2. Plasma Decay Half-Life (t1/2)

    Plasma decay half-life is the time measured for the plasma concentration to decrease by one half.

    Measured: 7 days

  3. Apparent Oral Clearance (CL/F)

    Clearance of a drug is a measure of the rate at which a drug is metabolized or eliminated by normal biological processes. Clearance obtained after oral dose (apparent oral clearance) is influenced by the fraction of the dose absorbed. Clearance was estimated from population pharmacokinetic (PK) modeling. Drug clearance is a quantitative measure of the rate at which a drug substance is removed from the blood.

    Measured: 7 days

  4. Apparent Volume of Distribution (Vz/F)

    plasma concentration of a drug. Apparent volume of distribution after oral dose (Vz/F) is influenced by the fraction absorbed.

    Measured: 7 days

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing [14C] PF-04449913 in people with Healthy, run by Pfizer 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 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 22 Jul 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 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?

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?

Area Under the Curve From Time Zero to Extrapolated Infinite Time [AUC (0 - 8)] (time frame: 7 days). The study lists 7 primary outcomes in all. 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 22 Jul 2014.
