Detailed Description:
The purpose is to evaluate the safety and pharmacokinetics of a single dose of PF-04995274 in healthy adult volunteers.

Ages Eligible for Study:   18 Years to 55 Years   (Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   Yes

Inclusion Criteria:

  • For all cohorts, healthy male and/or female subjects of nonchildbearing potential 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 heart rate measurement, 12 lead ECG and clinical laboratory tests).

Exclusion Criteria:

  • 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).
  • Pregnant or nursing women; women of childbearing potential. Female subjects must be of non childbearing potential defined by a history of surgical sterilization (eg, hysterectomy or bilateral oophorectomy) or post menopausal status (complete absence of menses for at least two consecutive years) and elevated FSH concentration in women between 45 and 55.
