Primary Outcome Measures:
  • AUCinf (Area under the plasma concentration-time profile from time zero extrapolated to infinite time) of metformin [ Time Frame: 0.5, 1.5, 2, 3, 4, 6, 8, 9, 10, 12 and 24 hours after the metformin dose on Day 4 ]
  • Cmax (Maximum plasma concentration) of metformin [ Time Frame: 0.5, 1.5, 2, 3, 4, 6, 8, 9, 10, 12 and 24 hours after the metformin dose on Day 4 ]
  • Clr (Renal clearance) of metformin [ Time Frame: 0.5, 1.5, 2, 3, 4, 6, 8, 9, 10, 12 and 24 hours after the metformin dose on Day 4 ]

Secondary Outcome Measures:
  • AUClast (Area under the plasma concentration-time profile from time zero to the time of the last quantifiable concentration) of metformin [ Time Frame: 0.5, 1.5, 2, 3, 4, 6, 8, 9, 10, 12 and 24 hours after the metformin dose on Day 4 ]
  • t½ (Terminal half-life) of metformin [ Time Frame: 0.5, 1.5, 2, 3, 4, 6, 8, 9, 10, 12 and 24 hours after the metformin dose on Day 4 ]
  • Tmax (Time for maximum plasma concentration) of metformin [ Time Frame: 0.5, 1.5, 2, 3, 4, 6, 8, 9, 10, 12 and 24 hours after the metformin dose on Day 4 ]
  • Ae24 (Cumulative amount of drug recovered unchanged in urine from time zero to 24 hours postdose) of metformin [ Time Frame: 0 hours and intervals 0-3, 3-6, 6-9, 9-12 and 12 24 hours after the metformin dose on Day 4 ]
  • Ae24% (Percent of dose recovered unchanged in urine from time zero to 24 hours postdose) of metformin [ Time Frame: 0 hours and intervals 0-3, 3-6, 6-9, 9-12 and 12 24 hours after the metformin dose on Day 4 ]
  • Clr (Renal clearance) over each collection interval for metformin [ Time Frame: 0 hours and intervals 0-3, 3-6, 6-9, 9-12 and 12 24 hours after the metformin dose on Day 4 ]
  • CP-690,550 plasma concentration at 2 hours postdose [ Time Frame: 2 hrs after first CP-690,550 dose on Day 4 ]

Estimated Enrollment: 24
Study Start Date: June 2011

Primary Completion Date: July 2011 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Metformin/CP-690,550 Drug: Metformin/CP-690,550
Single oral 500 mg dose of metformin on Days 1 and 4 and multiple oral 30 mg doses of CP-690,550 every 12 hours on Days 2-4.
