NCT03334253

Brief Summary

Study Objectives The objectives for this randomized trial are:

  1. 1.To determine the efficacy of daily low-dose atropine (0.01%) for slowing myopia progression over a two-year treatment period in children aged 5 to less than 13 years (Primary Outcome On-Treatment).
  2. 2.To determine the efficacy of atropine treatment on myopia progression 6 months following cessation of low-dose atropine treatment (Secondary Outcome Off-Treatment).

Outcome Measures

Primary Outcomes (1)

  • Treatment Group Comparison of Change in Spherical Equivalent Refractive Error.

    The primary analysis will be a treatment group comparison of change from baseline to 24-months in spherical equivalent refractive error (SER), as measured by a masked examiner using cycloplegic autorefraction (on-treatment comparison). The mean of the three readings from autorefraction in each eye will be calculated and then the mean of both eyes for each participant will be used for the analysis. The treatment group difference (atropine - placebo) and a 95% confidence interval will be calculated based on the model estimates at 24 months.

    At 24 months

Secondary Outcomes (1)

  • Treatment Group Comparison of Change From Baseline to 30 Months in Spherical Equivalent

    At 30 months

Study Arms (2)

  • Parent understands the protocol and is willing to accept randomization to atropine or placebo.
  • Is willing to participate in a 2 to 4 week run-in phase using daily artificial tear eyedrops.
  • Able to return in 2 to 4 weeks for possible randomization.
  • Parent has a phone (or access to phone) and is willing to be contacted by Investigator's site staff.
  • Relocation outside of the area of an active PEDIG site within next 32 months is not anticipated.

You may not qualify if:

  • Current or previous myopia treatment with atropine, pirenzepine or other anti-muscarinic agent.
  • Current or previous use of bifocals, progressive-addition lenses, or multi-focal contact lenses.
  • Current or previous use of orthoK, rigid gas permeable, or other contact lenses being used to reduce myopia progression.
  • Known atropine allergy.
  • Abnormality of the cornea, lens, central retina, iris or ciliary body.
  • Current or prior history of manifest strabismus, amblyopia, or nystagmus.
  • Prior eyelid, strabismus, intraocular, or refractive surgery.
  • Down syndrome or cerebral palsy.
  • Females who are pregnant, lactating, or intending to become pregnant within the next 30 months.
  • A negative urine pregnancy test will be required for all females who have experienced menarche.

Masking Details
Cycloplegic autorefraction, axial length, and additional biometry will be measured by a masked examiner at all follow-up visits using the same instrumentation on the participant throughout the study. Masking will be accomplished by having site personnel administer cyclopentolate to both eyes of each participant and wait 30 minutes before he/she sees the masked examiner. The masked examiner may be a technician or an investigator and must be certified to complete these measurements. Parents, patients, and investigators are also masked to treatment.
Purpose

Intervention Model
PARALLEL
Model Details: The current study is designed as an efficacy study, making effort to maximize adherence to treatment group assignments. After a run-in phase during which all participants are treated with daily artificial tear eyedrops for 2-4 weeks (and glasses are updated if required) to assess their ability to adhere to daily eye drops, participants are randomly assigned to daily atropine or placebo for 24 months, followed by 6 months off treatment.
