• A positive urine drug screen.

• Treatment with an investigational drug within 30 days (or as determined by the local requirement, whichever is longer) or 5 half-lives preceding the first dose of study medication.

Intervention

Drug:
• PF-03654764
5mg orally once daily for 10 days. After satisfactory review of the available safety, toleration and PK data, progression to the next dose will occur if the last dose was well tolerated. If the previous dose was not well tolerated, after review of the safety data, and discussion between the Pfizer Study Team and the Investigator, the same dose may be given again, a lower dose within the tolerated dose range may be given, or the study may be stopped. The dose increments will be based on emerging safety and toleration data, as well as plasma exposure estimates and forward predictions of PK. Nominal administered doses will not exceed 24 mg per day.
• placebo

If the previous dose was not well tolerated, after review of the safety data, and discussion between the Pfizer Study Team and the Investigator, the same dose may be given again, a lower dose within the tolerated dose range may be given, or the study may be stopped. The dose increments will be based on emerging safety and toleration data, as well as plasma exposure estimates and forward predictions of PK. Nominal administered doses will not exceed 24 mg per day.
• PF-03654764
