  • Ages 18 years and older
  • All sexes
  • No healthy volunteers
  • Adult, Older adult

Who may be able to join

  • Current biweekly or monthly silicone hydrogel contact lens wearer (excluding Air Optix® brand) and have worn these lenses bilaterally for at least three (3) months prior to Visit 1 (daily wear use only).
  • Symptoms of contact lens discomfort as defined by the protocol.
  • Habitual use of a biguanide-preserved multi-purpose solution for at least 30 days prior to Visit 1.

  • Other protocol-specified inclusion criteria may apply.

Who cannot join

  • Extended (over-night) contact lens wearer.
  • Any systemic or ocular disease or disorder (refractive disorder allowed and mild dry eye with successful contact lens wear is permitted), complicating factors or structural abnormality that would negatively affect the conduct or outcome of the study.

What is being measured

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

  1. Mean Change From Baseline in Investigator Rated Lid Papillae Maximum Score at Day 90

    Lid papillae (bumps on the inner eyelid) were assessed by the investigator using slit-lamp biomicroscopy and classified independently for the four palpebral zones (upper lid=1-3; lower lid=4) on a 5-point forced choice scale, where 0 = None; 1 = Slight (diffuse papillae); 2 = Mild (diffuse \& tufts papillae); 3 = Moderate (moderate \& tufts papillae); 4 = Severe (giant papillae). The maximum of the four zones was selected for the analysis. Both eyes were included in the model for analysis. A higher change value indicates a larger reduction in the severity of the lid papillae.

    Measured: Baseline (Day 0), Day 90

Secondary outcomes (3)
  1. Top 2 Box Percentage Agreement for "My Lenses Feel Like New" at Day 90

    As interpreted and reported by the subject on a questionnaire. A 5-point Likert scale was used, where 1=strongly disagree; 2=disagree; 3=undecided; 4=agree; 5=strongly agree. The Top-2-box response (agree, strongly agree) was calculated and reported as a percentage of all responses.

    Measured: Day 90

  2. Mean Frequency Score for Symptoms of Grittiness at Day 90

    As interpreted and reported by the subject on a questionnaire. The subject was asked, "During a typical day in the past 2 weeks, how often did your eyes feel gritty and/or scratchy while wearing your contact lenses?" and responded on a 5-point scale (1 = Never; 2 = Rarely; 3 = Sometimes; 4 = Frequently; 5 = Constantly).

    Measured: Day 90

  3. Mean Frequency Score for Symptoms of Dryness at Day 90

    As reported and interpreted by the subject on a questionnaire. The subject was asked "During a typical day in the past 2 weeks, how often did your eyes feel dry?" and responded on a 5-point scale ((0 = Never; 1 = Rarely; 2 = Sometimes; 3 = Frequently; 4 = Constantly).

    Measured: Day 90

Questions about this trial

What is this clinical trial studying?

A study testing Hydrogen peroxide-based contact lens solution, Habitual contact lens solution and Habitual contact lenses in people with Refractive Error, run by Alcon Research.

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 5 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: finished, as of the sponsor's last update on 8 Jun 2015. Status can change between updates, so confirm with the study contact before making plans.

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 8 Jun 2015). 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?

Mean Change From Baseline in Investigator Rated Lid Papillae Maximum Score at Day 90 (time frame: Baseline (Day 0), Day 90). 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 8 Jun 2015.
