This study is to evaluate the effect of multiple doses of itraconazole, the potent cytochrome
P450 enzymes (CYP3A) inhibitor, on the pharmacokinetics of PF-06648671 following a single
dose administration in healthy subject.

Full eligibility criteria for NCT02883114
Ages eligible for Study
18 Years to 55 Years
Genders eligible for Study
Accepts Healthy Volunteers
Healthy male and/or female subjects of non childbearing potential between the ages of 18 and 55 years at the time of screening, 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.
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.
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).
Hypersensitivity or previous adverse events due to azole antifungals.
A positive urine drug testing.
History of regular alcohol consumption exceeding 7 drinks/week for females or 14 drinks/week for males within 6 months of Screening.
Use of tobacco or nicotine containing products in excess of the equivalent of 5 cigarettes per day.
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.
Screening supine 12 lead ECG demonstrating corrected QT (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 AND at Day 0, as assessed by the study specific laboratory and confirmed by a single repeat, if deemed necessary:
Aspartate aminotransferase (AST)/ serum glutamic oxaloacetic transaminase (SGOT) or alanine aminotransferase (ALT)/serum glutamic pyruvic transaminase (SGPT) >1x 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.
Fertile male subjects 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, or longer based upon the compound's half life characteristics, after the last dose of investigational product.
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. 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.
History of hepatitis or positive testing for human immunodeficiency virus (HIV), hepatitis B surface antigen (HBsAg), hepatitis B surface antibody (HBsAb), hepatitis B core antibody (HBcAb) or hepatitis C antibodies (HCV). As an exception, a positive HBsAb finding as a result of subject vaccination is permissible.
Blood donation (excluding plasma donations) of approximately 1 pint (500 mL) or more within 60 days prior to dosing.
Unwilling or unable to comply with the Lifestyle Requirements described in this protocol.
Subjects who are investigator site staff members directly involved in the conduct of the study and their family members, site staff members otherwise supervised by the investigator, or subjects who are Pfizer employees, including their family members, directly involved in the conduct of the study.
Any condition possibly affecting drug absorption.
Have any medical conditions, medical history, or are taking any medications that are contraindicated in the itraconazole prescribing information.
Other acute or chronic medical or psychiatric condition including recent (within the past year) or active suicidal ideation or behavior or laboratory abnormality that may increase the risk associated with study participation or investigational product administration or may interfere with the interpretation of study results and, in the judgment of the investigator, would make the subject inappropriate for entry into this study.
