Study of Atropine Therapeutic Effect on Myopic Progression (STAMP)

February 21, 2023 updated by: LitePharmTech Co., Ltd.

A Multicenter, Randomized, Double-blind, Placebo-controlled Clinical Trial to Evaluate the Therapeutic Effect and Safety of LPTAT in Children With Myopia

This study is to evaluate the therapeutic effect and safety of LPTAT in children with myopia.

Study Overview

Detailed Description

The primary objective is to evaluate the superiority of LPTAT to placebo in slowing myopia progression through the change of SE(Spherical Equivalent), which is measured by cycloplegic autorefraction after 12-month treatment.
