Study Endpoints

Primary Endpoints

Change From Baseline (Day 0) in Cerebral Spinal Fluid (CSF) Amyloid Beta Peptide (Abeta) 42 and Abeta40 at Week 24
Baseline (Day 0) and Week 24

CSF Abeta biomarkers (Abeta42, Abeta40) were assessed at Baseline visit (Day 0) and Week 24 (Day 168). Change from Baseline in CSF Abeta42 and Abeta40 are summarized. Baseline and Week 24 study visits were taken place at approximately the same time of day in the morning (preferably between 08:00 and 12:00) to improve the reliability of CSF. Baseline value was defined as the latest Day 0 value. Change from Baseline was calculated as post-dose (Week 24) visit value minus Baseline value. The data is presented in for adjusted mean and standard error of adjusted mean.

Change From Baseline (Day 0) in CSF Abeta42/ Abeta40 Ratio at Week 24
Baseline (Day 0) and Week 24

CSF Abeta biomarkers (Abeta42, Abeta40) were assessed at Baseline visit (Day 0) and Week 24 (Day 168). Change from Baseline in CSF Abeta42/Abeta40 ratio is summarized. Baseline and Week 24 study visits were taken place at approximately the same time of day in the morning (preferably between 08:00 and 12:00) to improve the reliability of CSF. Baseline value was defined as the latest Day 0 value. Change from Baseline was calculated as post-dose (Week 24) visit value minus Baseline value. The data is presented in for adjusted mean and standard error of adjusted mean.

Change From Baseline (Day 0) in CSF Tau and Phosphorylated Tau (P-tau) Measures at Week 24
Baseline (Day 0) and Week 24

CSF tau and P-tau were assessed at Baseline visit (Day 0) and Week 24 (Day 168). Change from Baseline in CSF tau and P-tau was summarized. Baseline and Week 24 study visits were taken place at approximately the same time of day in the morning (preferably between 08:00 and 12:00) to improve the reliability of CSF. Baseline value was defined as the latest Day 0 value. Change from Baseline was calculated as post-dose (Week 24) visit value minus Baseline value. The data is presented in for adjusted mean and standard error of adjusted mean.

Change From Baseline (Day 0) in the Computerized Test Battery for Cognition (CogState) Battery Working Memory/Executive Function (WM/EF) Composite Score at Week 24
Baseline (Day 0) and Week 24

The WM/EF composite score was comprised of 5 functional tests including 1) Controlled oral word association which measured language fluency, planning and working memory, 2) Category naming: It measures semantic fluency, planning and working memory, 3) One-back: This is a measure of working memory. 4) Trail B: This is a measure of motor speed, visual scanning, and visual-motor integration. This test required attention and cognitive flexibility. 5) Go No-Go task: This test evaluate accuracy and reaction time for each response. The composite score calculated by standardizing the total score: sum of all responses obtained from these 5 functional test by using the formula (Total score of ITT population at baseline - Total score at Week 24) /standard deviation of mean total mean score at baseline. The observed composite score ranged from minimum -1.474 and maximum 1.596. Lower score means better cognitive status. Change from Baseline was calculated as post-dose visit minus Baseline value.
