Groups2
Neither group, or both, names a comparator, so the groups keep ClinicalTrials.gov's order.
| Group | Title | Description | With the outcome | Analysed | ClinicalTrials.gov code |
|---|---|---|---|---|---|
| Group 1 | PF-03654746 and Donepezil | PF-03654746 0.25 milligram (mg) powder in capsule orally once daily on Day 1 to 5, followed by PF-03654746 0.5 mg powder in capsule orally once daily on Day 6 to 10 and PF-03654746 1 mg powder in capsule orally once daily on Day 11 to 15 during the forced titration phase. PF-03654746 0.5 mg to 2 mg powder in capsule orally once daily, based on investigator's discretion and tolerability, on Day 16 to 30 during the flexible titration phase.
