ABOUT THIS STUDY
1. Male and female participants must be 18 to 55 years of age, inclusive, at the time of signing the ICD.
2. Healthy female participants of nonchildbearing potential and/or male participants who are overtly healthy as determined by medical evaluation including medical history, physical examination, laboratory tests, and cardiovascular tests.
3. Participants who are willing and able to comply with all scheduled visits, treatment plan, laboratory tests, and other study procedures.
4. BMI of 17.5 to 30.5 kg/m2; and a total body weight >50 kg (110 lbs).
5. Capable of giving signed informed consent and compliance with study requirements and restrictions
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. Any condition possibly affecting drug absorption (eg, gastrectomy).
3. History of HIV infection, hepatitis B, or hepatitis C; positive testing for HIV,
HBsAg, HBcAb, or HCVAb. Hepatitis B vaccination is allowed.
4. Other medical or psychiatric condition including recent (within the past year) or
active suicidal ideation/behavior or laboratory abnormality that may increase the risk
of study participation or, in the investigator's judgment, make the participant
inappropriate for the study.
5. Use of prescription or nonprescription drugs and dietary and herbal supplements within
7 days or 5 half-lives (whichever is longer) prior to the first dose of study
Prior/Concurrent Clinical Study Experience:
6. Previous administration with an investigational drug within 30 days (or as determined
by the local requirement) or 5 half-lives preceding the first dose of study
intervention used in this study (whichever is longer).
7. A positive urine drug test.
8. Screening supine BP ≥140 mm Hg (systolic) or ≥90 mm Hg (diastolic), following at least
5 minutes of supine rest. If BP is ≥140 mm Hg (systolic) or ≥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 participant's eligibility.
9. Baseline 12 lead ECG that demonstrates clinically relevant abnormalities that may
affect participant safety or interpretation of study results (eg, baseline QTc
interval >450 msec, complete LBBB, signs of an acute or indeterminate age myocardial
infarction, ST T interval changes suggestive of myocardial ischemia, second or third
degree AV block, or serious bradyarrhythmias or tachyarrhythmias). If the baseline
uncorrected QT interval is >450 msec, this interval should be rate corrected using the
Fridericia method and the resulting QTcF should be used for decision making and
reporting. 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 participant's eligibility. Computer interpreted ECGs should be overread
by a physician experienced in reading ECGs before excluding participants.
10. Participants 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:
- AST or ALT level greater than or equal to 1.5 × upper limit of normal (ULN);
- Total bilirubin level greater than or equal 1.5 × ULN; participants 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 greater than or
11. History of alcohol abuse 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
(male) and 4 (female) or more alcoholic drinks in about 2 hours. As a general rule,
alcohol intake should not exceed 14 units per week (1 unit = 8 ounces (240 mL) beer, 1
ounce (30 mL) of 40% spirit or 3 ounces (90 mL) of wine).
12. Blood donation (excluding plasma donations) of approximately 1 pint (500 mL) or more
within 60 days prior to dosing.
13. History of sensitivity to heparin or heparin induced thrombocytopenia.
14. Unwilling or unable to comply with the criteria in the Lifestyle Considerations
section of this protocol.
15. Investigator site staff or Pfizer employees directly involved in the conduct of the
study, site staff otherwise supervised by the investigator, and their respective
16. Use of tobacco or nicotine-containing products in excess of the equivalent of 5
cigarettes per day.
