Amblyopia Clinical Trial
Official title:
A 16 Week Randomized, Single-masked, Multicenter Proof of Concept Study of Binocular Videogames Versus Patching for Amblyopia in Children 4-7 Years of Age With an Open-label Substudy of Binocular Videogames in Children 8-12 Years of Age
The purpose of this PoC study was to evaluate the potential therapeutic efficacy of binocular video games played on a tablet and to compare the efficacy of binocular video games versus patching in amblyopic patients 4 to 7 years old (Part A) as well as to gain experience with binocular video games in older children population of 8 to12 years old (Part B). Part A and Part B was designed to provide long term data on durability of binocular video games treatment. The study consisted of two parts, Part A: randomized, single masked PoC study in children 4 to 7 years old at Screening, and Part B: open-label substudy in children 8 to 12 year old at Screening.
The clinical investigation consisted of 2 parts: - Part A: a single-masked, randomized clinical investigation in subjects 4 to 7 years of age. - Part B: an open-label, non-randomized sub-investigation in subjects 8 to 12 years of age. Part A was a 16-week, prospective, randomized, single-masked, multicenter, controlled, 2 arm, parallel-group clinical investigation in subjects 4 to 7 years of age with amblyopia. Subjects were randomly assigned in a 1:1 ratio to either binocular videogame treatment for 8 to 12 weeks or patching treatment for 16 weeks. Randomization was stratified by severity of amblyopia in eligible subjects (moderate amblyopia with best-corrected visual acuity (BCVA) of the amblyopic eye of 20/100 or better, or severe amblyopia with BCVA of the amblyopic eye worse than 20/100). Part B was a 16-week, open-label, single arm sub investigation in subjects 8 to 12 years of age with amblyopia, in which selected sites could participate. Subjects received binocular videogame treatment for 8 weeks, followed by 8 weeks of follow-up. ;
