NCT02151617

Brief Summary

The purpose of this study in healthy people is to evaluate safety, toleration and time course of plasma concentration of multiple oral doses of PF-06743649. The pharmacodynamic activity of PF-06743649 will also be assessed. The effect of food on PK of PF-06743649 will also be investigated.

Sexall
Healthy VolunteersYes
Age GroupsAdult (18-64)

You may qualify if:

  • 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 \>50 kg (110 lbs).
  • Evidence of a personally signed and dated informed consent document indicating that the subject (or a legally acceptable representative) has been informed of all pertinent aspects of the study.

You may not qualify if:

  • 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).
  • Any condition possibly affecting drug absorption (eg, gastrectomy).
  • Evidence of gout/hyperuricemia, measured sUA \>8 mg/dL at screening.
  • Experienced an episode of nephrolithiasis or ureterolithiasis.
