The overall study methods are as follows.
[Clinical Trials Schedules] The study consists of a screening period(Visit 1) of up to 30 to 50 days, blood collection visits(Visit 2) for IP generation and administration visits for IP administration(Visit 3), with a follow-up(FU) period of 90 days(Visit 4
7). During the Follow-up(FU) Period, subjects will visit 4 times for safety, tolerability and efficacy evaluation, with 90 Day being the End of Study(EOS) Visit.
[Subject screening and blood collection for IP generation] During Screening Period, subjects will be informed about the study and asked if they want to participate. The subjects and representatives and the caregiver/study partner will be asked to sign consent forms before any study-specific procedures are performed. Screening procedures will be performed to assess whether the subject is eligible to participate in the study. A minimum of approximately 200 mL of the subject's blood will be collected ≥30 days before Baseline and shipped to the IP Manufacturing Agency for generation of the IP. Subjects are required to refrain from consuming alcohol ≥3 days before any blood samples for IP generation are collected. If required (e.g. due to contamination), additional blood samples for IP generation may be collected during an unscheduled visit.

The primary objective of this study is to evaluate the safety and tolerability of multiple intravenous (IV) infusions at a single dose strength of GB301 in subjects with mild to moderate AD.

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.
