Myopia Progression After Ceasing Myopia Control Contact Lens Wear

June 18, 2018 updated by: Johnson & Johnson Vision Care, Inc.
This is a continuation study for subjects who were previously fit with test or control lenses; all will stop wearing their study lenses assigned in the previous study and will start to wear an FDA-approved marketed spherical soft contact lens.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

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

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. 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.
Interventional

Enrollment (Actual)

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.
82

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

9 years to 13 years (CHILD)

Accepts Healthy Volunteers

Yes

Genders Eligible for Study

All

Description

Inclusion Criteria:

  1. The subject must be enrolled in the parent protocol for at least one year.
  2. The subject's parent or legal guardian must read and sign the STATEMENT OF INFORMED CONSENT and the subject must read and sign the Child's Assent Form and be provided a copy of each form.
  3. The subject must appear able and willing to adhere to the instructions set forth in this clinical protocol.

Exclusion Criteria:

  1. Ocular or systemic allergies that may interfere with contact lens wear.
  2. Systemic disease or autoimmune disease or use of medication (e.g. antihistamine), which may interfere with contact lens wear.
  3. Clinically significant (grade 3 or 4) corneal edema, corneal vascularization, corneal staining or any other abnormality of the cornea, which may contraindicate contact lens wear.
  4. Clinically significant (grade 3 or 4) tarsal abnormalities or bulbar injection that might interfere with contact lens wear.
  5. Any ocular infection.
  6. Any corneal distortion resulting from previous hard or rigid gas permeable contact lens wear.
  7. Any infectious disease (e.g. hepatitis, tuberculosis) or an immunosuppressive disease (e.g. HIV)
  8. Diabetes
  9. Previous refractive surgery, orthokeratology, keratoconus, or other corneal irregularity in either eye. Rigid contact lens wearers cannot be enrolled in the study.
  10. Strabismus.
  11. Pupil or lid abnormality or infection in either eye
  12. Central corneal scar in either eye
  13. Aphakia in either eye
  14. Contraindications to contact lens wear such as dry eye or history of prior unsuccessful contact lens wear.
  15. History of participation in prior clinical trials aimed to control myopia progression, except for the parent trial
  16. Surgically altered eyes, ocular infection of any type, ocular inflammation.
  17. Anterior chamber angle grade 2 or narrower by Van Herrick method.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Axial Length of the Eye
Time Frame: Baseline and every 6 months post-baseline up to 18 months
Axial length was measured with the IOLMaster at baseline and then every 6 months throughout the course of the study. Five measurements were collected at each visit from the subject's right eye and the average of the 5 measurements was used for the analysis.
Baseline and every 6 months post-baseline up to 18 months
Spherical Equivalent Refractive Error
Time Frame: Baseline and every 6 months up to 18 months
Cycloplegic spherical equivalent refraction of the subjects's right eye was computed from the sphero-cylindrical refraction measured with an open-field auto refractor. The median of 5 repeated measurements, each of which was the average of 3 consecutive readings, was used for the analysis.
Baseline and every 6 months up to 18 months

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Major Dates

Study Start

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.

Primary Completion (ACTUAL)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
