February 12, 2018 updated by: Pfizer

A Phase 1, Randomized, Double-blind, Sponsor-open, Placebo-controlled, First-in-human Study To Evaluate The Safety, Tolerability, And Pharmacokinetics Of Single Ascending Oral Doses Of Pf-06852231 Administered To Healthy Adult Subjects

The purpose of this study is to evaluate the safety, tolerability, and pharmacokinetics of single ascending doses of PF-06852231 after first-time administration to healthy adult subjects.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 55 years (Adult)

No

Genders Eligible for Study

Description

Inclusion Criteria:

  1. Healthy female subjects of non-childbearing potential and male subjects, who at the time of screening are between 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 electrocardiogram, or clinical laboratory tests.
  2. Body mass index of 17.5 to 30.5 kg/m2; and a total body weight >50 kg (110 lb).
  3. Subjects who are willing and able to comply with all scheduled visits, treatment plan, laboratory tests, and other study procedures.

Exclusion Criteria:

  1. Evidence or history of clinically significant hematological, renal, endocrine, pulmonary, gastrointestinal, cardiovascular, hepatic, psychiatric, neurological, or allergic disease (including drug allergies, but excluding untreated, asymptomatic, seasonal allergies at the time of dosing).
  2. Treatment with an investigational drug within 30 days (or as determined by the local requirement) or 5 half-lives preceding the first dose of investigational product (whichever is longer).
  3. Screening supine BP greater than or equal to 140 mm Hg (systolic) or greater than or equal to 90 mm Hg (diastolic), following at least 5 minutes of supine rest. If BP is greater than or equal to 140 mm Hg (systolic) or greater than or equal to 90 mm Hg (diastolic), the BP should be repeated 2 more times and the average of the 3 BP values should be used to determine the subject's eligibility.
  4. Screening supine 12-lead ECG demonstrating a corrected QT (QTc) interval >450 msec or a QRS interval >120 msec. If QTc exceeds 450 msec, or QRS exceeds 120 msec, the ECG should be repeated 2 more times and the average of the 3 QTc or QRS values should be used to determine the subject's eligibility.

  5. 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 test, if deemed necessary:

    • Aspartate aminotransferase (AST) or alanine aminotransferase (ALT) level greater than or equal to 1.5x upper limit of normal (ULN);
    • Total bilirubin level greater than or equal to 1.5x ULN; subjects with a history of Gilbert's syndrome may have direct bilirubin measured and would be eligible for this study provided the direct bilirubin level is less than or equal to ULN.
  6. 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 investigational product.
  7. Unwilling or unable to comply with the criteria in the Lifestyle Requirements section of this protocol.
  8. Other acute or chronic medical or psychiatric conditions

Time Frame: Baseline up to 14 days after last dose of study medication
Treatment-related AE are any untoward medical occurrence attributed to study drug in a participant who received study drug. Treatment-emergent are events between first dose of study drug and up to Y days after last dose that were absent before treatment or that worsened relative to pretreatment state. Relatedness to study drug is assessed either yes or no by the investigator. Participants with multiple occurrences of an AE within a category are counted once within the category.

Number of Participants With Laboratory Abnormalities
Time Frame: Baseline up to 14 days after last dose of study medication
Following parameters were analyzed for laboratory examination: hematology (hemoglobin, hematocrit, red blood cell count, platelet count, white blood cell count, total neutrophils, eosinophils, monocytes, basophils, lymphocytes); blood chemistry (blood urea nitrogen, creatinine, glucose, calcium, sodium, potassium, chloride, total bicarbonate, aspartate aminotransferase, alanine aminotransferase, total bilirubin, alkaline phosphatase, uric acid albumin, total protein); urinalysis (decimal logarithm of reciprocal of hydrogen ion activity [pH], glucose, protein, blood, ketones, microscopy[if urine tested positive for blood or protein]).
