Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 40 participants
Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double (Participant, Investigator)
Official Title: An Investigator And Subject-Blind Phase 1 Study To Characterize The Safety, Tolerability, Pharmacokinetics And Pharmacodynamics Of Multiple Doses Of PF-03382792 In Healthy Elderly Subjects
Study Start Date : November 2010
Estimated Primary Completion Date : April 2011
Estimated Study Completion Date : April 2011

Arm Intervention/treatment
Experimental: Dosing
Ascending Doses
Drug: PF-03382792 0.5mg
0.5 mg PF-03382792, qd, for 14 days or placebo
Drug: PF-03382792 1.5 mg
1.5 mg PF-03382792, qd, for 14 days or placebo
Drug: PF-03382792 5 mg

Primary Outcome Measures :
  1. Safety Endpoints include: AEs, vital signs, triplicate ECGs, [ Time Frame: Day 0 to Day 28 ]
  2. Safety Endpoints include: Cosyntropin Stimulation Test, Clinical Examinations, Slit Lamp Examination, Aldosterone Concentrations [ Time Frame: Day 0 to Day 28 ]
  3. 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 ]
  4. 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 ]
  5. 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 ]

Secondary Outcome Measures :
  1. No secondary outcomes [ Time Frame: No secondary outcomes ]
