Study Summary

This is a drug-drug interaction study to compare the pharmacokinetics of a 2 mg oral dose of midazolam in adult healthy women of non-childbearing potential when administered alone and when administered along with 8 daily 125 mg doses of PD-0332991. Volunteers will be randomized to one of two sequences. Volunteers in sequence 1 will receive midazolam alone in treatment period 1, followed by multiple dose PD-0332991 and midazolam in treatment period 2. Volunteers randomized to sequence 2 will receive multiple dose PD-0332991 and midazolam in treatment period 1, and following a washout period of no less than 14 days they will receive midazolam alone in treatment period 2.

Primary Outcome

AUC (0 - 8)= Area under the plasma concentration versus time curve (AUC) from time zero (pre-dose) to extrapolated infinite time (0 - 8). It is obtained from AUC (0 - t) plus AUC (t - 8).
