Further study details as provided by Pfizer:

Primary Outcome Measures:
  • maximum plasma concentration (Cmax), time of maximum plasma concentration (Tmax), and apparent clearance from plasma (CL/F) [ Time Frame: 1 day ]
  • amount of PD 0332334 eliminated unchanged in urine during the 96-hour collection period (Ae96) [ Time Frame: 5 days ]
  • PD 0332334 area under the curve from 0 to infinity (AUCinf), PD 0332334 area under the curve from 0 to last quantifiable concentration (AUClast), [ Time Frame: 5 to 17 days depending on cohort ]
  • PD 0332334 renal clearance (CLr), apparent volume of distribution (Vz/F), terminal half life (t1/2), [ Time Frame: 5 to 17 days depending on cohort ]

Secondary Outcome Measures:
  • Adverse events, ECG, physical exams, clinical safety laboratory, and vital signs [ Time Frame: 5 to 17 days ]
