PRIMARY outcome

Timeframe: Up to 24 weeks

Population: Safety population (SAF) This population consisted of all randomized patients who received at least one dose of study medication and had at least one safety assessment after baseline.

The primary variable of this study is the percentage of patients having an AE leading to study drug discontinuation during the 24-week double-blind treatment period.

SECONDARY outcome

Timeframe: Baseline, 8,16, and 24 weeks

Population: Full analysis set (FAS): includes all randomized patients who received at least one dose of study drug and had at least one pre- and post-baseline assessment for any of the efficacy variables. n is the number of patients with an assessment at baseline and the corresponding visit.

The Alzheimer's Disease Assessment Scale - Japan cognitive subscale (ADAS-J cog) was used to measure change in cognitive function. The ADAS-J cog score ranges from 0-70, with higher total scores indicating more impairment. A negative change score indicates improvement from baseline.

SECONDARY outcome

Timeframe: Baseline and 24 weeks

Population: Full analysis set (FAS): The FAS includes all randomized patients who received at least one dose of study drug and had at least one pre- and post-baseline assessment for any of the efficacy variables. n is the number of patients with an assessment at baseline and the corresponding visit.

The MMSE was used to measure severity of Alzheimer's disease. The test consists of 2 parts: language (time orientation, registration and attention) and performance (recall, response to written/verbal commands, sriting ability and reproduction of complex polygons); 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 J-CGIC is simple 7 grade investigator's impression scale (1. Markedly improved, 2. Improved, 3. Slightly improved, 4. No change, 5. Slightly aggravated, 6. Aggravated, 7. Markedly aggravated) and a patient is defined to have improvement if J-CGIC tool the values 1, 2, or 3.

SECONDARY outcome

Timeframe: Up to 24 weeks

Population: Safety population (SAF) This population consisted of all randomized patients who received at least one dose of study medication and had at least one safety assessment after baseline. Patients were analyzed according to the treatment group they were assigned to at randomization.

Treatment retention rate at effective dose is defined as the proportion of patients who met all the followings - 1) completed the study, 2) received rivastigmine patch 18 mg/day throughout the last 8 weeks 3) received 18 mg/day for ≥75% of the days during the last 8 weeks
