Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.

Enrollment (Estimated)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.
58

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

11 years to 17 years (Child)

Accepts Healthy Volunteers

  • Have successfully completed the 4-year MiSight® Analysis of Progression (MAP) Study;
  • Are established soft contact lens wearers (including myopia control contact lens designs);
  • Have read and signed the study consent or assent form, as appropriate for their age;
  • Have a parent or legal guardian who has read and signed the Parent/Guardian Information Sheet (PIS) and Consent Form;
  • Are willing and able to follow study instructions and maintain the appointment schedule;
  • Are willing to wear the study contact lenses for 10 hours/day and 5 days per week as an ideal target while participating;
  • Require a spherical contact lens power correction between -0.50 and -6.00 D;

  • Continue to demonstrate acceptable fit and handling with the study contact lenses.

Exclusion Criteria:

  • Are participating in any concurrent clinical or interventional study;
  • Have worn rigid gas-permeable (including orthokeratology) contact lenses within the previous 30 days;
  • Have used atropine concentrations above 0.01% for myopia control in the previous 30 days;
