Обзор

Multicentric, double blind, randomized, comparative study with two parallel group: study group vs placebo group. 5 visits: inclusion visit \[day (D) 0\] and 4 follow-up visits (D30, D60, D90, and D120).

Подробное описание

This is a prospective, double blind, multicentric and comparative study including 5 visits (on D0 which corresponds to inclusion visit, D30, D60, D90, and D120).
