Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 18 to 45 years
  • All sexes
  • No healthy volunteers
  • Adult

Who may be able to join

  • The subject must be between 18 and 45 years of age (inclusive) with no presbyopic add.
  • The subject must read, understand, and sign the STATEMENT OF INFORMED CONSENT and receive a fully executed copy of the form. This should be recorded on the Case Report Form (CRF).
  • The subject must be willing to wear the study lenses for at least 8 hours per day, 7 days per week.
  • The subject must be a current successful soft contact lens wearer in both eyes
  • The subject must appear able and willing to adhere to the instructions set forth in this clinical protocol.
  • The subject's subjective refraction must result in a vertex corrected spherical contact lens prescription in the range of -1.00D to -6.00D in each eye.
Show all 15Show fewer
  • The subject's refractive astigmatism must be less than or equal to 0.75D in both eyes.
  • The subject must have best corrected visual acuity of 20/30 (6/9) or better in each eye.
  • The subject must require a visual correction in both eyes (no monofit or monovision allowed).
  • The subject must have normal eyes with no evidence of abnormality or disease. For the purposes of this study a normal eye is defined as one having:
  • No amblyopia.
  • No evidence of lid abnormality or infection (including blepharitis/meibomitis).
  • No conjunctival abnormality or infection.
  • No clinically significant slit lamp findings (i.e. stromal edema, vascularization, infiltrates or abnormal opacities).
  • No other active ocular disease.

Who cannot join

  • Any ocular or systemic allergies or diseases that may interfere with contact lens wear.
  • Any systemic disease, autoimmune disease, or use of medication, which may 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 11Show fewer
  • Pregnancy or lactation.
  • No extended wear in the last 3 months.
  • Diabetes.
  • Infectious diseases (e.g. hepatitis, tuberculosis) or an immunosuppressive disease (e.g. HIV).
  • Employee or family member of the staff of the investigational site.

What is being measured

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

  1. Subject Reported Ease of Removal

    Measured on a 5 point-scale of excellence (excellent, very good, good, fair and poor) per a participant. Outcome is reported as aggregate number of subjects who reported Excellent/Very Good at their 1-week visit.

    Measured: 6-10 Days

Secondary outcomes (4)
  1. Subject Reported Overall Comfort

    Measured on a 5 point-scale of excellence (excellent, very good, good, fair and poor) per a participant. Summary is reported as an aggregate of Excellent/Very Good at their 1-week visit.

    Measured: 6-10 Days

  2. Subject Reported Overall Vision

    Measured on a 5 point-scale of excellence (excellent, very good, good, fair and poor) per a participant using an aggregate summary of excellent/very good at their 1-week visit.

    Measured: 6-10 Days

  3. Binocular Snellen Visual Acuity

    Snellen visual acuity percentage of eyes with a visual acuity of eyesight testing at a 20/20 level or better by eye.

    Measured: 6-10 Days

  4. Overall Corneal Staining

    Proportion of subjects that have corneal staining on the 0-4 the NEI/Industry Workshop guidelines scale, measured by eye.

    Grade 1 or higher is reported as a percentage of total eyes.

    Measured: 6-10 Days

Questions about this trial

What is this clinical trial studying?

A study testing delefilcon A and etafilcon A in people with Myopia, run by Johnson & Johnson Vision Care, Inc. at 10 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 15 inclusion and 11 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 10 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 4 Jun 2014). 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?

Subject Reported Ease of Removal (time frame: 6-10 Days). 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.
