Study Endpoints
Primary Endpoints
All events and physical and neurological function and score change from baseline to 24 weeks in ratings for cognitive and global function scales
6 mo extension study: week 24
The primary endpoints will be the change from baseline in ADAS-Cog total score and ADCS-CGIC total score.
weeks 12, 14, 26 and 40.
Evaluation of the effects of multiple doses of lecozotan SR on the PK profile of a single dose of digoxin in healthy adult subjects
Pharmacokinetic (PK) analyses
To assess the effect of drug administration on QTc interval.
The incidence of adverse events and adverse reactions will be calculated. The safety variables (vital signs, ECG parameters, and routine laboratory tests) and PK parameters will be measured throughout study period.
Secondary Endpoints
Score change from baseline to 24 weeks on functional and behavioral scales
week 24
Secondary efficacy outcome variables include additional cognitive, functional,and behavioral measures.
weeks 12, 14, 26 and 40.
