Participant Flow

Patients receiving Exelon patch 5 cm\^2 were more than those receiving Exelon capsule for 4 weeks as least, because some patients had interrupted Exelon capsule for few days in the middle of 4-week Exelon capsule treatment, but still switched to Exelon patch 5 cm2

SECONDARY outcome

Timeframe: Baselin, week 16, 28 and 52

Population: ITT population: All enrolled subjects who received 3 mg b.i.d Exelon capsule orally for 4 weeks and at least one dose of Exelon patch therapy

The changes in Mini-Mental Status Examination (MMSE) of patients with Alzheimer's disease treated with Exelon 5 cm\^2 Patch at Week 28 and Exelon 10 cm2 Patch at Week 52 versus baseline, the treatment-switching day at Week 4. MMSE is a multi-item instrument that examines orientation, registration, attention, calculation, recall, visuospatial ability and language. The total score can range from 0 to 30, with a higher score indicating better function. A positive change score indicates improvement from baseline. The assessments will be conducted at Visit 1, 2, 8, 11 and 17 (screening, Week 4 (baseline), 16, 28 and 52).

SECONDARY outcome

Timeframe: Baseline, week 16, 28 and 52

Population: ITT population: All enrolled subjects who received 3 mg b.i.d Exelon capsule orally for 4 weeks and at least one dose of Exelon patch therapy.

The changes in Alzheimer Disease Assessment Scale-Cognitive Subscale (ADAS-Cog) of patients with Alzheimer's disease treated with Exelon 5 cm\^2 Patch at Week 28 and Exelon 10 cm\^2 Patch at Week 52 versus baseline, the treatment-switching day at Week 4. ADAS-Cog has been used as the major cognitive measure of anti-dementia drugs. The total score range is 0 to 70 points, with higher scores indicating greater cognitive impairment. The assessments will be conducted at Visit, 2, 8, 11 and 17 (Week 4 (baseline), 16, 28 and 52).

The discontinuation rate due to the treatment switching from oral capsule to patch treatment. For patients who discontinue earlier due to intolerance of patch treatment, the proportion will be analyzed. Both the discontinuation rate of 5 cm2 and 10 cm\^2 patch therapy will be presented.
