A Phase 3 Clinical Study of QLM3004 in Delaying Myopia in Children

A Phase 3, Multicenter, Randomized, Double-Blind, Placebo-Controlled, Parallel-Group Study to Evaluate the Efficacy and Safety of Different Concentrations of QLM3004 in Delaying the Progression of Myopia in Children

Efficacy and Safety Study of QLM3004 in Myopic Children

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.
