Interventions

DRUG

PF-03654746

20-day dose titration phase: all dosages in capsules starting at 0.25 mg qd x 5 d, then 0.5 mg qd x 5 d, then 1.0 mg qd x 5 d, then 2.0 mg qd x 5 d. If a subject has intolerable, severe, or serious AEs after taking 2 mg qd for 1 to 5 days of dosing, the dose will be decreased by the investigator to 1 mg qd. If, in the investigator's opinion, the subject is determined to be unlikely to tolerate continued dosing at a dose of 1 mg qd, the subject should be discontinued from the study. Subjects remaining in the study will proceed to the 3-week Stable Dosing Phase; doses will be 2 mg daily x 21 days or 1 mg daily x 21 days.
