Primary Outcome Measures:
  • Lithium pharmacokinetic endpoints: area under curve from 0 to infinity (AUCinf), area under curve from 0 to last quantifiable concentration (AUClast), half-life (T1/2), and maximum serum concentration (Cmax). [ Time Frame: 10 days ]
  • The nature, incidence, duration, and severity of adverse events; discontinuation due to adverse events; clinical safety lab; 12-lead ECG; and vital signs will be monitored in this study. [ Time Frame: 10 days ]

Secondary Outcome Measures:
  • No Secondary Outcomes [ Time Frame: No Secondary Outcomes ]

Enrollment: 0
Study Start Date: May 2009
Estimated Study Completion Date: June 2009
Estimated Primary Completion Date: June 2009 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Cohort 1a
Subjects are treated with single dose lithium first. Then after at least 7 day washout, the subjects start PD 0332334 treatment from day 1 to day 9. At day 4 of PD 0332334 treatment, single dose lithium is given to subjects.
Drug: Lithium
300 mg lithium, oral, once initially and then again at day 4 of PD 0332334 treatment
Drug: PD 0332334
225 mg q12h PD 0332334, oral, 9 days treatment
Other Name: imagabalin
Experimental: Cohort 1b
Subjects are treated with PD 0332334 from day 1 to 9 and a single dose of lithium is given at day 4. After at least 7 day washout, the subjects are treated with single dose of lithium.
Drug: Lithium
300 mg lithium, oral, at day 4 of PD 0332334 treatment and after 7 day washout
Drug: PD 0332334
225 mg q12h PD 0332334, oral, 9 days treatment
