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
  • All sexes
  • Healthy volunteers accepted
  • Adult

Who may be able to join

  • Healthy male and/or female subjects of non-childbearing potential 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).
  • 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 and females that do NOT have a documented hysterectomy, bilateral oophorectomy and/or ovarian failure) 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 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).
  • 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 rest. If BP is >=140 mm Hg (systolic) or >=90 mm Hg (diastolic), repeat per local standard operating procedures (SOP). If orthostatic changes are present and deemed to be clinically significant by the investigator, Subject can be excluded.
  • For subjects who answer "Yes" to the Columbia Suicide Severity Rating Scale (C-SSRS) questions 4 or 5, a risk assessment should be done by a qualified mental health professional (MHP: a psychiatrist or licensed PhD level clinical psychologist) to assess whether it is safe for the subject to participate in the study. In addition, subjects deemed by the investigator to be at significant risk of suicidal or violent behavior should be excluded.

What is being measured

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

  1. Number of Participants with categorical scores on the Columbia Suicide Severity Rating Scale (C-SSRS)

    C-SSRS assessed whether participant experienced following: completed suicide (1), suicide attempt (2) (response of "Yes" on "actual attempt"), preparatory acts toward imminent suicidal behavior (3)("Yes" on "preparatory acts or behavior"), suicidal ideation (4) ("Yes" on "wish to be dead", "non-specific active suicidal thoughts", "active suicidal ideation with methods without intent to act or some intent to act, without specific plan or with specific plan and intent), any suicidal behavior or ideation, self-injurious behavior (7)("Yes" on "Has subject engaged in non-suicidal self-injurious behavior").

    Measured: screening,Day 28

Secondary outcomes (21)
  1. Maximum Observed Plasma Concentration (Cmax) after single dose

    Cmax after a single dose

    Measured: 0-Day 5

  2. Area Under the Curve From Time Zero to Last Quantifiable Concentration (AUClast) after single dose

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

    Measured: 0-Day 5

  3. Area Under the Curve From Time Zero to Extrapolated Infinite Time [AUC (0 - inf)] after single dose

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

    Measured: 0-Day 5

  4. Time to Reach Maximum Observed Plasma Concentration (Tmax) after single dose

    Tmax after single dose

    Measured: 0-Day 5

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

    Measured: 0-Day 5

  6. Apparent Oral Clearance (CL/F) after single dose

    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 after single dose

    Measured: 0-Day 5

  7. Apparent Volume of Distribution (Vz/F) after single dose

    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.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing PF-06669571 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 8 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 6 Sep 2018. 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?

Number of Participants with categorical scores on the Columbia Suicide Severity Rating Scale (C-SSRS) (time frame: screening,Day 28). 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 6 Sep 2018.
