  • Ages 18 to 55 years
  • All sexes
  • Healthy volunteers accepted
  • Adult

Who may be able to join

  • Healthy female subjects of non-childbearing potential and/or male subjects who, at the time of screening, are 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 or clinical laboratory tests. Female subjects of non-childbearing potential must meet at least one of the following criteria:
  • Achieved postmenopausal status, defined as follows: cessation of regular menses for at least 12 consecutive months with no alternative pathological or physiological cause; and have a serum follicle-stimulating hormone (FSH) level confirming the post-menopausal state;
  • Have undergone a documented hysterectomy and/or bilateral oophorectomy;
  • Have medically confirmed ovarian failure. All other female subjects (including females with tubal ligations) will be considered to be of childbearing potential.
  • Body Mass Index (BMI) of 17.5 to 30.5 kg/m2; and a total body weight >50 kg (110 lbs).
  • Evidence of a personally signed and dated informed consent document indicating that the subject has been informed of all pertinent aspects of the study.
  • Subjects who are willing and able to comply with all scheduled visits, treatment plan, laboratory tests, and other study procedures.
  • Subject must be willing to avoid direct sunlight exposure or any high intensity ultraviolet light exposure, from the first day of dosing with study medication and until the follow-up visit; and to apply sun cream/lotion with a high sun protection factor, as appropriate.

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 the time of dosing).
  • Any condition possibly affecting drug absorption (eg, gastrectomy).
  • A positive urine drug screen.
  • History of regular alcohol consumption exceeding 14 drinks/week for females or 21 drinks/week for males (1 drink = 5 ounces (150 mL) of wine or 12 ounces (360 mL) of beer or 1.5 ounces (45 mL) of hard liquor) within 6 months of Screening.
  • Treatment with an investigational drug within 30 days (or as determined by the local requirement) or 5 half-lives preceding the first dose of study medication (whichever is longer).
  • Screening supine blood pressure >140 mm Hg (systolic) or >90 mm Hg (diastolic), following at least 5 minutes of supine rest. If blood pressure (BP) is >140 mm Hg (systolic) or >90 mm Hg (diastolic), the BP should be repeated two more times and the average of the three BP values should be used to determine the subject's eligibility.
Show all 19Show fewer
  • Screening supine 12-lead ECG demonstrating QTc >450 msec or a QRS interval >120 msec. 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 or QRS values should be used to determine the subject's eligibility.
  • Subjects with ANY of the following abnormalities in clinical laboratory tests at screening, as assessed by the study-specific laboratory and confirmed by a single repeat, if deemed necessary:
  • Aspartate aminotransferase (AST)/serum glutamic oxaloacetic aminotransferase (SGOT) or alanine aminotransferase (ALT)/serum glutamic pyruvic aminotransferase (SGPT) >1.5 x upper limit of normal (ULN);
  • Total bilirubin >1.5 x ULN; subjects with a history of Gilbert's syndrome may have a direct bilirubin measured and would be eligible for this study provided the direct bilirubin is <ULN.
  • Pregnant female subjects; breastfeeding female subjects; male subjects with partners currently pregnant; male subjects able to father children who are unwilling or unable to use a highly effective method of contraception as outlined in this protocol for the duration of the study and for at least 28 days after the last dose of investigational product or longer based upon the compound's half-life characteristics.
  • Use of prescription or nonprescription drugs and dietary supplements within 7 days or 5 half-lives (whichever is longer) prior to the first dose of study medication. As an exception, acetaminophen/paracetamol may be used at doses of <1 g/day. Limited use of non-prescription medications that are not believed to affect subject safety or the overall results of the study may be permitted on a case-by-case basis following approval by the sponsor. Herbal supplements and hormone replacement therapy must be discontinued at least 28 days prior to the first dose of study medication.

What is being measured

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

  1. Number of participants with Adverse Events (AEs)

    Number of participants with AEs occurring after first dose of study drug. Relatedness to study drug will be assessed by investigator.

    Measured: Baseline up to 1 day of dosing

  2. Number of subjects with standard safety laboratory test results of potential clinical significance

    Number of subjects with standard safety laboratory test results of potential clinical significance (according to pre-defined criteria).

    Measured: Baseline up to 1 day of dosing

  3. Electrocardiogram (ECG)

    Absolute values and changes from baseline for the ECG parameters

    Measured: 0, 1, 2, 4, 8, 12, 24, 48, and 72 hours post-dose

  4. Orthostatic blood pressure and pulse rate

    Absolute values and changes from baseline for blood pressure and pulse rate

    Measured: 0, 1, 2, 4, 8, 12, 24, 48, and 72 hours post-dose

  5. Abnormal rhythms as observed on continuous cardiac telemetry

    All abnormal rhythms will be reviewed by the study physician for the presence of rhythms of potential clinical concern. The time, duration and description of any clinically significant event will be recorded.

    Measured: Baseline period of at least 2 hours and continuous tracing for at least 8 hours following single dose administration

Secondary outcomes (7)
  1. Maximum Observed Plasma Concentration (Cmax)

    Maximum Observed Plasma Concentration (Cmax)

    Measured: 0, 0.5, 1.5, 2, 4, 6, 8, 10, 12, 16, 24, 36, 48, and 72 hours post-dose

  2. Time to Reach Maximum Observed Plasma Concentration (Tmax)

    Time to Reach Maximum Observed Plasma Concentration (Tmax)

    Measured: 0, 0.5, 1.5, 2, 4, 6, 8, 10, 12, 16, 24, 36, 48, and 72 hours post-dose

  3. 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: 0, 0.5, 1.5, 2, 4, 6, 8, 10, 12, 16, 24, 36, 48, and 72 hours post-dose

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

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

    Measured: 0, 0.5, 1.5, 2, 4, 6, 8, 10, 12, 16, 24, 36, 48, and 72 hours post-dose

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

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

    Measured: 0, 0.5, 1.5, 2, 4, 6, 8, 10, 12, 16, 24, 36, 48, and 72 hours post-dose

  6. 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: 0, 0.5, 1.5, 2, 4, 6, 8, 10, 12, 16, 24, 36, 48, and 72 hours post-dose

  7. Apparent Volume of Distribution (Vz/F)

    Volume of distribution is defined as the theoretical volume in which the total amount of drug would need to be uniformly distributed to produce the desired plasma concentration of a drug. Apparent volume of distribution after oral dose (Vz/F) is influenced by the fraction absorbed.

    Measured: 0, 0.5, 1.5, 2, 4, 6, 8, 10, 12, 16, 24, 36, 48, and 72 hours post-dose

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing PF-06266047 in people with Healthy Volunteers, run by Pfizer at 1 site in Belgium.

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 8 inclusion and 19 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 24 Jun 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 Belgium. 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. Some participants in this study may receive a placebo. 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?

Number of participants with Adverse Events (AEs) (time frame: Baseline up to 1 day of dosing). The study lists 5 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 24 Jun 2016.
