- Healthy male and/or female subjects 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 and pulse rate
measurement, 12 lead ECG and clinical laboratory tests).
- Body Mass Index (BMI) of 17.5 to 30.5 kg/m2; and a total body weight >45 kg (99 lbs).
- Evidence of a personally signed and dated informed consent document indicating that
the subject (or a legal representative) has been informed of all pertinent aspects of
- Subjects who are willing and able to comply with 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).
- A positive urine drug screen.
- History of regular alcohol consumption exceeding 14 drinks/week for females or 21
drinks/week for men (1 drink = 5 ounces (150 mL) of wine or 12 ounces (360 mL) of beer

- 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 5 half lives preceding the
first dose of study medication.
- 12 lead ECG demonstrating QTc >450 msec at Screening. If QTc exceeds 450 msec, the ECG
should be repeated two more times and the average of the three QTc values should be
used to determine the subject's eligibility.
- Pregnant females; breastfeeding females; males and females of childbearing potential
who are unwilling or unable to use a highly effective method of nonhormonal
contraception as outlined in this protocol for the duration of the study and for at
least 28 days after the last dose of investigational product. Male subjects who are
unwilling to use effective contraception (eg, barrier or abstinence) during the study.
- 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 study medication. Herbal
supplements and hormonal methods of contraception (including oral and transdermal
contraceptives, injectable progesterone, progestin subdermal implants, progesterone
releasing IUDs, postcoital contraceptive methods) and hormone replacement therapy must
be discontinued 28 days prior to the first dose of study medication. Depo Provera must
be discontinued at least 6 months prior to the first dose of study medication. 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.

- 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 directly involved in the conduct of
- Other severe acute or chronic medical or psychiatric condition 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.
