Demonstrate a superiority of at least one dose of S 18986 vs. placebo on verbal episodic memory performance in patients with MCI over 12 months. |
|
E.2.2 | Secondary objectives of the trial |
- Demonstrate a superiority of at least one dose of S 18986 vs. placebo of non verbal episodic memory and other cognitive domains performance in patients with MCI over 12 months. - Demonstrate a superiority of at least one dose of S 18986 vs. placebo in the activities of daily living, the patient self-perception of his/her memory impairment, and the clinician global impression of change in patients with MCI over 12 months. - Show a reduction or a stabilization of hippocampal and whole brain atrophy using MRI in MCI patients treated with S 18986 for 12 months vs. placebo. - Show a lower number of conversion to AD with S 18986 vs. placebo over 12 months. - Assess safety and acceptability of S 18986 in patients with MCI over 12 months. - Collect plasma concentrations of S 18986 and its metabolite Y 1255 in order to compare the level with previous studies. |
