Trial summary

Increasing number of myopic children and significant complications of high myopia enhance the necessity of effective control strategy. Instillations of low-dose atropine have been shown to reduce myopia progression in Asian populations but its effect in non-Asian populations is still unclear. Read more about this study

About this study

Official title: Open Prospective With Historical Control Clinical Study of 0.01 % Atropine Sulfate Effectiveness in Controlling of Myopia Progression in Children

Increasing number of myopic children and significant complications of high myopia enhance the necessity of effective control strategy. Instillations of low-dose atropine have been shown to reduce myopia progression in Asian populations but its effect in non-Asian populations is still unclear. This open prospective study with historical control is designed to investigate if 0.01% atropine can reduce myopia progression in Russian children, taking into account a change of difference between manifest and cycloplegic refraction, as well as, myopia progression rate at the time of recruitment.

Read the detailed description

The study is designed to test the following hypotheses:

  • 0.01% atropine one drop nightly is safe and with no significant side effects.
  • nightly instillations of 0.01% atropine does not influence tear production.
  • 0.01% atropine one drop nightly reduces the progression of childhood myopia in Russian children.
  • nightly instillations of 0.01% atropine decreases the manifest refraction and, consequently, difference between manifest and cycloplegic refractions.
  • effectiveness of 0.01% atropine depends on the age and myopia progression rate at the time the therapy was started.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. change in axial length

    Change in axial length elongation from baseline to 12 months, as measured using IOLMaster, compared with historical data

    Measured: baseline - 12 months

  2. change in myopic progression rate

    Change in myopic progression rate measured as the difference between cycloplegic refraction from baseline to 12 months, compared with historical data.

    Measured: baseline - 12 months

Secondary outcomes (3)
  1. change in difference between manifest and cycloplegic refractions

    change in difference between manifest and cycloplegic (tropicamide 0.5%) refractions, measured with autorefractometer, compared with historical data

    Measured: baseline - 12 months

  2. change in positive relative accommodation

    change in positive relative accommodation, measured in maximal spectacles correction by using concave lenses until the image blurs

    Measured: baseline - 12 months

  3. tear production

    result of Schirmer I test

    Measured: baseline - 12 months

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing 0.01% Atropine sulfate solution in "Comfort Drops" ("AVIZOR S.A.", Spain) in people with Myopia, run by The V.P. Vyhodcev Eye Hospital at 1 site in Russia.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 9 Apr 2020. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Russia. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Each site lists its own contact: choose the nearest one under Trial locations. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

change in axial length (time frame: baseline - 12 months). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 9 Apr 2020.
