\"MyopiaEye care practitioners can prescribe several therapies for slowing progression in children and adolescents. Currently, no monotherapy has been shown in randomized controlled trials (RCTs) to stop myopia progression completely. Therefore, research continues to discover more efficacious interventions.<\/span><\/p>\n

The complexity, length, and cost of myopia clinical trials for regulatory approval can be challenging, especially for start-up companies. The U.S. Food and Drug Administration (FDA) currently requires a three-year RCT. However, the regulatory bar appears more reasonable in other markets such as the European Union, Canada, and Australia\/New Zealand. An interesting complication for myopia control is that both medical devices and pharmacological treatments slow the progression of childhood myopia. It remains uncertain how the FDA will approach comparisons of myopic control devices and myopia control pharmacological interventions as different groups currently review them within the FDA.\u00a0<\/span><\/p>\n

As the regulatory pathway to obtain the coveted \u201cmyopia progression control\u201d labeling indication can be lengthy, some treatments have entered clinical practice before regulatory approval through peer-reviewed papers of academic investigator-led trials. The availability of on-label and off-label myopia control therapies creates challenges for conducting placebo-controlled RCTs, including ethics, recruitment, retention, selective loss of faster progressors, and non-protocol treatments.\u00a0<\/span><\/p>\n

The authors propose that future myopia control clinical trials may adopt one of the following designs:<\/span><\/p>\n
