Eligibility Criteria
Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.
Inclusion Criteria
2. Body Mass Index (BMI) of 17.5 to 30.5 kg/m2; and a total body weight \>50 kg (110 lbs).
3. Evidence of a personally signed and dated informed consent document indicating that the subject has been informed of all pertinent aspects of the study.
4. Subjects who are willing and able to comply with study confinement period, scheduled visits, treatment plan, laboratory tests, contraceptive requirements and other study procedures.
Exclusion Criteria
1. 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).
2. Any clinically significant malabsorption condition (eg, gastrectomy, bowel resection).
3. A positive urine drug screen for drugs of abuse or recreational drugs.
4. History of human immunodeficiency virus (HIV), hepatitis B, or hepatitis C; positive testing for HIV, hepatitis B surface antigen (HepBsAg), hepatitis B core antibody (HepBcAb), or hepatitis C antibody (HCVAb).
5. History of abuse of alcohol or binge drinking and/or any other illicit drug use or dependence within 6 months of Screening. Binge drinking is defined as a pattern of 5 or more alcoholic drinks (male) in about 2 hours. As a general rule, alcohol intake should not exceed 21 units per week (1 unit = ½ pint beer, 25 mL of 40% spirit or a 125 mL glass of wine).
6. Use of tobacco/nicotine containing products in excess of 5 cigarettes/day.
7. Treatment with an investigational drug within 60 days.
8. Total 14C radioactivity measured in plasma exceeding 11 mBq/mL.
9. Screening supine blood pressure \>=140 mm Hg (systolic) or \>=90 mm Hg (diastolic), following at least 5 minutes of supine rest. If blood pressure is \>=140 mm Hg (systolic) or \>=90 mm Hg (diastolic), the blood pressure measurement should be repeated two more times and the average of the three measurements should be used to assess the subject's eligibility.
10. Supine 12 lead ECG demonstrating QTcF \>450 msec or a QRS interval \>120 msec at screening. If QTcF exceeds 450 msec, or QRS exceeds 120 msec, the ECG should be repeated two more times and the average of the three QTcF or QRS values should be used to determine the subject's eligibility.
11. Use of prescription or nonprescription drugs (including vitamins 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 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 Pfizer.
12. Use of herbal supplements within 28 days prior to the first dose of study medication.
13. Blood donation (excluding plasma donations) of no more than 100 mL or more within 56 days prior to dosing.
14. An estimated glomerular filtration rate of \<90 mL/min/1.73 m2 based on the four variable Modification of Diet in Renal Disease (MDRD) equation.
15. History of tuberculosis or active or latent or inadequately treated infection, positive QuantiFERON TB Gold test.
16. Any medical history of disease (ie, Gilbert's disease) that has the potential to cause a rise in total bilirubin over the upper limit of normal (ULN).
17. 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:
* Serum aspartate aminotransferase (AST) or alanine aminotransferase (ALT) \>=1.5 × ULN, total serum bilirubin \>= 25.6 micromol/L;
* Hemoglobin =\<2.17 mmol/L (males).
18. Known participation in a clinical trial for PF 04965842 within 60 days prior to the first dose of study medication.
19. Serious adverse reaction or serious hypersensitivity to any drug or the formulation excipients.
20. Unwilling or unable to comply with the Lifestyle Requirements described in this protocol.
21. Subjects who are investigational 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.
22. Systemic therapy with any of the following medications that are CYP3A4 inhibitors within 7 days or 5 half lives (whichever is longer) or CYP3A inducers within 28 days prior to the first dose of the trial medication, or during the trial (Section 5.7).
23. History of sensitivity to heparin or heparin induced thrombocytopenia.
24. 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.
25. Subjects with conditions that affect their ability to taste ie, dysgeusia, respiratory infection, cold, etc.
26. 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 90 days after the last dose of investigational product.
