  • Ages 18 to 39 years
  • All sexes
  • No healthy volunteers
  • Adult

Who may be able to join

  • The subject must be at least 18 years of age and no more than 39 years of age.
  • The subject is a current spherical soft contact lens wearer (defined as a minimum of 6 hours of DW for a minimum of 1 month prior to the study) and willing to wear the study lenses on a daily wear basis (defined as a minimum of 6 hours of wear per day at least five days of the week) for the duration of the study.
  • The subject's optimal vertexed spherical equivalent distance correction must be between -1.00 and - 9.00D.
  • Any cylinder power must be ≤ -0.75D.
  • The subject must have visual acuity best correctable to 20/25+3 or better for each eye.
  • The subject must read and sign the Statement of Informed Consent.
  • The subject must appear able and willing to adhere to the instructions set forth in this clinical protocol.

Who cannot join

  • Ocular or systemic allergies or disease which might interfere with contact lens wear.
  • Systemic disease or use of medication which might interfere with contact lens wear.
  • Clinically significant (grade 3 or 4) corneal edema, corneal vascularization, corneal staining, or any other abnormalities of the cornea which would contraindicate contact lens wear.
  • Clinically significant (grade 3 or 4) tarsal abnormalities or bulbar injection which might interfere with contact lens wear.
  • Any ocular infection.
  • Any corneal distortion resulting from previous hard or rigid gas permeable contact lens wear.
Show all 10Show fewer
  • Pregnancy or lactation.
  • Diabetes.
  • Infectious diseases (e.g. hepatitis, tuberculosis) or an immuno-suppressive disease (e.g. HIV).

What is being measured

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

  1. Visual Acuity Monocular

    Snellen monocular visual acuity measurement

    Measured: after 1 week of lens wear

  2. Visual Acuity Binocular

    Snellen binocular visual acuity measurement

    Measured: after 1 week of lens wear

  3. Subjective Assessment of Lens Comfort

    Contact Lens User Experience (CLUE)TM questionnaire: A validated patient-reported outcomes questionnaire to assess patient-experience attributes of soft, disposable contact lenses (comfort, vision, handling, and packaging) in a contact-lens wearing population in the US, ages 18-65. Scores follow a normal distribution with a population average score of 60 (SD 20), where higher scores indicate a more favorable/positive response.

    Measured: after 1 week of lens wear

  4. Subjective Assessment of Quality of Vision

    Contact Lens User Experience (CLUE)TM questionnaire: A validated patient-reported outcomes questionnaire to assess patient-experience attributes of soft, disposable contact lenses (comfort, vision, handling, and packaging) in a contact-lens wearing population in the US, ages 18-65. Scores follow a normal distribution with a population average score of 60 (SD 20), where higher scores indicate a more favorable/positive response.

    Measured: after 1 week of lens wear

Secondary outcomes (3)
  1. Limbal Redness

    Scale of 0 to 4, where 0=None, 2=Trace, 3=Mild, 4=Moderate, 5=Severe.

    Measured: after 1 week of lens wear

  2. Bulbar Redness

    Scale of 0 to 4, where 0=None, 2=Trace, 3=Mild, 4=Moderate, 5=Severe.

    Measured: after 1 week of lens wear

  3. Subjective Assessment of Lens Comfort

    Contact Lens User Experience (CLUE)TM questionnaire: A validated patient-reported outcomes questionnaire to assess patient-experience attributes of soft, disposable contact lenses (comfort, vision, handling, and packaging) in a contact-lens wearing population in the US, ages 18-65. Scores follow a normal distribution with a population average score of 60 (SD 20), where higher scores indicate a more favorable/positive response.

    Measured: 10 minutes after lens insertion at time of initial lens fitting

Questions about this trial

What is this clinical trial studying?

A study testing galyfilcon A prototype lens and lotrafilcon B lens in people with Myopia, run by Johnson & Johnson Vision Care, Inc. at 2 sites in United States.

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 7 inclusion and 10 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: finished, as of the sponsor's last update on 19 Jun 2018. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in United States. 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.

Are results available for this study?

Yes. Results are posted in the registry (first posted 25 Jan 2012). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Visual Acuity Monocular (time frame: after 1 week of lens wear). The study lists 4 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 19 Jun 2018.
