Clinical Trial Summary

The investigators intend to perform exploratory evaluation of the treatment effectiveness and safety of PM012 Tablet of PuriMED Co., Ltd. at 2 doses in Korean patients with mild to moderate dementia of Alzheimer's type. To achieve this, this study aims to compare each dose with placebo control for the efficacy and safety to explore the clinically optimal dose of PM012 Tablet for therapeutic confirmatory (phase 3) clinical studies.

3. Study objectives

1. Primary objective

• To compare the efficacy of 2 doses of PM012 Tablet and placebo based on cognitive effect assessed by ADAS-cog at Week 12 post-dose

2. Secondary objectives

• To compare the efficacy of 2 doses of PM012 Tablet and placebo based on cognitive effect assessed by ADAS-cog at Week 8 post-dose

• To compare the efficacy of 2 doses of PM012 Tablet and placebo based on overall functional effect assessed by CDR at Weeks 8 and 12 post-dose

• To compare the efficacy of 2 doses of PM012 Tablet and placebo based on activities of daily living assessed by K-IADL at Weeks 8 and 12 post-dose

• To compare the efficacy of 2 doses of PM012 Tablet and placebo based on behavioral changes assessed by NPI at Weeks 8 and 12 post-dose

• To compare the efficacy of 2 doses of PM012 Tablet and placebo based on cognitive effect assessed by K-MMSE at Weeks 8 and 12 post-dose

• To compare the efficacy of 2 doses of PM012 Tablet and placebo based on improvement on VAS assessed by Senile Dementia Pattern Identification Diagnosis System at Weeks 8 and 12 post-dose

3. Dose group 2

• Efficacy population:42, Drop-out(20%)included:53

4. Total

• Efficacy population:126, Drop-out(20%)included:159

8. Study method

• This study is designed to be a multicenter, randomized, double-blind, parallel placebo group and 2 dose groups, phase 2 clinical study in patients with dementia of Alzheimer's type aged ≥ 50 and ≤ 85 years.

• Once a subject voluntarily provides the written consent to participate in the study, he/she will be randomized only if meeting the inclusion criteria and exclusion criteria through screening test. Randomized subjects will receive the study drug or the placebo for 12 weeks.
