A Single Dose Study Of Antimineralocorticoid Activity Of PF-03882845 In Healthy Volunteers

A Phase 1, Double-Blind (Sponsor-Open), Placebo- And Active-Controlled, Single Dose, Crossover Study To Assess Antimineralocorticoid Activity Of Oral Pf-03882845 In Healthy Subjects.

24-hr urinary sodium/potassium ratio will be a sensitive biomarker of antimineralocorticoid activity. The dose-response relationship of the antimineralocorticoid activity of PF-03882845 can be established following single oral doses.

Inclusion Criteria:

• Male and/or female healthy volunteers, age 18 to 55 years. Females must be of non-childbearing potential.
• Body Mass Index (BMI) of 17.5 to 30.5 kg/m2; and a total body weight >50 kg (110 lbs).
• Subjects who are willing and able to comply with scheduled visits, treatment plan, laboratory tests, diet restrictions and other trial procedures.

Exclusion Criteria:

• Subjects with a supine BP >140 mm Hg systolic or >90 mm Hg diastolic or <100 mm Hg systolic or <60 mm Hg diastolic based on the average of the triplicate
• Serum potassium >=5.1 mmol/L or <3.5 mmol/L at screening, confirmed by a single repeat if deemed necessary.
• Estimated GFR <60 mL/min/1.73 m2 using the Cockcroft-Gault formula measurement of the individual parameters following at least 5 minutes of rest at Screening.
