Overview
Efficacy and Safety Study of QLM3004 in Myopic Children
Description
The study was divided into 2 phases, with Stage 1 being the primary efficacy and safety confirmation phase and Stage 2 a post-withdrawal observation period.
Stage 1:To evaluate the safety and efficacy of 3 concentrations of QLM3004 compared to Vehicle (placebo)for slowing the progression of myopia in children over a 96-week treatment period.
Stage 2:subjects will enter Period 2 of the study, and Period 2 will be a post-withdrawal observation period, which will not serve as a validation basis for the efficacy and safety of QLM3004.
