ABOUT THIS STUDY
Subjects must meet all of the following inclusion criteria to be eligible for enrollment in the study:
1. Healthy female subjects and/or male subjects who, at the time of screening, are 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 (BP) and pulse rate measurement, 12 lead ECG, or clinical laboratory tests.
Female subjects of non childbearing potential must meet at least 1 of the following criteria:
1. Achieved postmenopausal status, defined as follows: cessation of regular menses for at least 12 consecutive months with no alternative pathological or physiological cause; status may be confirmed with a serum follicle stimulating hormone (FSH) level confirming the postmenopausal state;
2. Have undergone a documented hysterectomy and/or bilateral oophorectomy;
3. Have medically confirmed ovarian failure. All other female subjects (including female subjects with tubal ligations) are considered to be of childbearing potential.
2. Body mass index (BMI) of 17.5 to 30.5 kg/m2 and a total body weight >50 kg (110 lb).

Subjects with any of the following characteristics/conditions will not be included in the
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). Evidence of acute exacerbation of
dermatological condition (eg, AD, eczema or psoriasis) or visible rash present during
physical examination. Subjects with history of psoriasis, AD or eczema can be included
in the study.

4. A positive urine drug test.
5. History of regular alcohol consumption exceeding 14 drinks/week for female subjects or
21 drinks/week for male subjects (1 drink = 5 ounces [150 mL] of wine or 12 ounces
[360 mL] of beer or 1.5 ounces [45 mL] of hard liquor) within 6 months before

requirement) or 5 half lives preceding the first dose of investigational product
(whichever is longer).
7. Screening supine systolic BP <90 mm Hg or >140 mm Hg following at least 5 minutes of
supine rest OR Screening supine diastolic BP <50 mm Hg or >90 mm Hg following at least
5 minutes of supine rest.
If a subject meets any of these criteria, 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.
8. 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.
9. Pregnant female subjects; breastfeeding female subjects; fertile male subjects and
female subjects of childbearing potential who are unwilling or unable to use 1 highly
effective method of contraception as outlined in this protocol Contraception section
for the duration of the study and for at least 28 days after the last dose of
10. 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 1.5 ×
upper limit of normal (ULN);
- Total bilirubin level 1 × 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 ULN.

isoniazid) or inducers (eg, aprepitant, carbamazepine, enzalutamide, rifampin,
ritonavir, nevirapine, phenobarbital, and St. John's Wort) within 28 days or 5 half
lives (whichever is longer) prior to dosing.
13. Use of CYP3A4 inhibitors (eg, ketoconazole, ciprofloxacin, diltiazem) or other
inducers (eg, phenytoin, carbamazepine) within 28 days or 5 half lives (whichever is
longer) prior to dosing.
14. Known relevant history of elevated liver function tests (LFTs) or impaired liver

therapy, or considered clinically significant by the investigator within 6 months

As an exception, acetaminophen/paracetamol may be used at doses of < 1 g/day. Limited
use of nonprescription 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.
