Brief Summary:
A new tablet form of PF-04531083 has been manufactured. Previously the compound was administered as a solution/suspension to healthy volunteers. This study will investigate the pharmacokinetics of PF-044531083 in tablet form and compare with the pharmacokinetics obtained, with the same dosing regimen, with the solution/suspension.

Condition or disease Intervention/treatment Phase
Chronic Pain Drug: PF-04531083 Phase 1

Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 24 participants
Allocation: Non-Randomized
Intervention Model: Parallel Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: A Phase 1, Open Label Study To Investigate The Pharmacokinetics Of Multiple Doses Of PF-04531083 Tablets In Healthy Volunteers
Study Start Date : May 2010
Primary Completion Date : July 2010
Study Completion Date : July 2010

Arm Intervention/treatment
Active Comparator: Cohort 1: PF-04531083 Drug: PF-04531083
Dosed as a tablet in 100mg strengths. Dosage in the first cohort will be 300mg twice daily for 3 days followed by 200mg twice daily for 11 days
Active Comparator: Cohort 2: PF-04531083 Drug: PF-04531083
Dosed as a tablet in 100mg strengths. Dosage in this optional second cohort will be optimised based on the data arising from Cohort 1

Primary Outcome Measures :
  1. concentration of PF-04531083 in blood just before dosing on the 8th day of the study [ Time Frame: Days 1 and 8 of the study ]

Secondary Outcome Measures :
  1. pharmacokinetic parameters derived from the plasma concentration versus time profile of PF-04531083 following single and multiple dosing. AUCtau, Cmax, Tmax will be calculated. [ Time Frame: Days 1, 8 and 14 of the study ]
