Patients having caregivers who submit written consent for cooperative involvement in this study, can routinely stay with patients 3 days a week (at least 4 hours a day), provide patients' information necessary for this study, assist treatment compliance and escort their patients on required visits to study institution.
Exclusion criteria
1. Patients with a complication of serious neuropsychiatric disease(s) such as stroke, brain tumor, schizophrenia, epilepsy, normal pressure hydrocephalus, mental retardation, brain trauma with unconsciousness, and/or who underwent brain surgery causing unsolved deficiency. 2. Patients with severe complication of cardiovascular, hepatic, renal, hematological, or other diseases unable to secure the safety. 3. Pregnant or lactating women, or women who are willing to become pregnant no later than 1 month after the scheduled study completion. 4. Patients with severe extrapyramidal disorders (Hoehn and Yahr staging score is greater than IV). 5. Patients whose systolic blood pressure is less than 90 mmHg or pulse rate is less than 50 beats/min.
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Change From Baseline in Mini-mental State Examination (MMSE) Total | Baseline, Week 52, and Week 52 LOCF | MMSE measured general cognitive functioning: orientation, memory, attention, calculation, language, visuospatial functions. Total score derived from sub-scores; total ranged from 0 - 30, where a higher score indicated better cognitive state. |
| Change From Baseline in Neuropsychiatric Inventory (NPI) Score of Psychiatric Symptoms | Baseline, Week 52, and Week 52 LOCF | NPI measured 10 different domains of psychiatric symptoms including delusion and hallucination. Each domain is scored for: present or absent, frequency, and severity. The score derived from sub-scores; total ranged from 0 to 120, higher score indicated worse neuropsychiatric outcomes. |

Outcome results
Change From Baseline in Mini-mental State Examination (MMSE) Total
MMSE measured general cognitive functioning: orientation, memory, attention, calculation, language, visuospatial functions. Total score derived from sub-scores; total ranged from 0 - 30, where a higher score indicated better cognitive state.
Time frame: Baseline, Week 52, and Week 52 LOCF
Population: Efficacy Analysis Set: subjects who received at least one dose of E2020 and also provided safety assessment data after baseline, with at least one available efficacy evaluation. Two subjects whose diagnosis was suspected not to meet clinical criteria of probable DLB and 2 subjects with lack of efficacy data were excluded from the efficacy analysis.
