Description

Summary

This study evaluates the progression of myopia in participants using microdosed atropine 0.01%, atropine 0.1%, or placebo ophthalmic solution. Eligible subjects will administer study medication daily in each eye for 48 months. Efficacy and safety assessments will be performed at visits scheduled for 1, 6, 12, 18, 24, 30 and 36 months after initiation of medication use. Subjects will be re-randomized at the 36 month visit, then followed at 6 month intervals for an additional year.

Official Title

A Multicenter, Double-Masked, Randomized, Placebo-Controlled Phase 3 Study of the Safety and Efficacy of Atropine 0.1% and 0.01% Ophthalmic Solutions Administered With a Microdose Dispenser for the Reduction of Pediatric Myopia Progression (The CHAPERONE Study)

Details

Subjects will be evaluated for eligibility during an initial Screening Visit and enrolled after signing the study-specific informed consent form(s). Eligible subjects must complete a run-in period where they use the microdose dispenser to administer study drug "vehicle" solution daily in both eyes. After run-in, subjects return for a Baseline Visit and additional study eligibility assessments. Subjects who continue to be eligible will be equally randomized to one of the following treatment groups:

  • Microdose atropine 0.1% ophthalmic solution
  • Microdose atropine 0.01% ophthalmic solution
  • Microdose placebo ophthalmic solution

Randomization will be stratified by iris color (e.g., dark and light) and study site. Study enrollment will be limited to a maximum of 50% of subjects who self-identify as East Asian ethnicity. Subjects will use their assigned study medication daily in both eyes and return for efficacy and safety assessments at 1, 6, 12, 18, 24, 30, and 36 months.

At the Month 36 Visit, subjects in the 2 atropine dose arms will be re-randomized to either placebo or 1 of the 2 doses of atropine ophthalmic solution, while subjects originally assigned to placebo will be re-randomized to one of the 2 atropine ophthalmic solution arms. After re-randomization, all subjects will be followed for an additional year with efficacy and safety examinations at Months 42 and 48.

You can join if…

Open to people ages 3-12

  • Refractive error by cycloplegic autorefraction: myopia -1.00 D to -6.00 D in both eyes; astigmatism ≤ 1.50 D in both eyes; anisometropia < 1.50 D.
  • Best-corrected distance visual acuity in current correction of 0.2 logMAR or better with interocular difference ≤ 0.1 logMAR.
  • Refractive correction for each eye meets the following criteria: myopia within ± 0.50 D of the manifest refraction at the Screening Visit; cylinder power within ± 0.50 D of the manifest refraction at the Screening Visit; when cylinder power is < 1.00 D, axis within ± 15 degrees of the manifest refraction; when cylinder power is ≥ 1.00 D, axis within ± 5 degrees of the manifest refraction.
