Primary Outcome Measures:
  • Safety Endpoints include: AEs, vital signs, triplicate ECGs, [ Time Frame: Day 0 to Day 28 ] [ Designated as safety issue: Yes ]
  • Safety Endpoints include: Cosyntropin Stimulation Test, Clinical Examinations, Slit Lamp Examination, Aldosterone Concentrations [ Time Frame: Day 0 to Day 28 ] [ Designated as safety issue: Yes ]
  • Safety Endpoints include: safety laboratory endpoints (including a complete blood count and a full chemistry panel, including electrolytes, hepatic transaminases, and urinalysis, with microscopic analysis if dipstick analysis is positive), [ Time Frame: Day 0 to Day 28 ] [ Designated as safety issue: Yes ]
  • Pharmacokinetic endpoints include: Plasma concentrations of PF 03382792 and its N dealkylated metabolite, PF 03227077, will be measured and used to determine Cmax, Tmax, AUC on Day 1 and Css,max, Tss,max, AUC, Css,min, Css,avg on Days 7 and 14. [ Time Frame: Day 0 to Day 28 ] [ Designated as safety issue: No ]
  • Additional pharmacokinetic endpoints: the accumulation ratio (Rac) will be determined from Day 14 and Day 1 AUC. If data permit, t1/2 and urinary excretion parameters (CLR for the parent and Ae and Ae%) will be calculated. [ Time Frame: Day 0 to Day 28 ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • No secondary outcomes [ Time Frame: No secondary outcomes ] [ Designated as safety issue: No ]
