About this study

Official title: Evaluation of Enfilcon A Soft Contact Lens Compared to Galyfilcon A Soft Contact Lens

The primary objective of thes study is to confirm that the ocular response to the Test lenses are similar to those of the Control lenses when used in a 1 week planned replacement, daily wear modality over a 1-month period.

Read the detailed description

The test lens and control lens were randomized in a 2:1 ratio to evaluate the test lens and control contact lens.

What is being measured

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

  1. Objective Assessment: Ocular Response - Biomicroscopy

    The primary safety endpoint are the objective slit lamp findings associated with the enfilcon A contact lenses compared with those same findings reported as associated with the galyfilcon A contact lenses.

    The incidence of biomicroscopy findings (0=not present, 4=severe) over the duration of the study with the highest reported grade was chosen for each unique eye. Biomicroscopy measurements were obtained at Baseline/Dispensing (baseline and dispensing visit combined), Post-Dispensing (after lenses were dispensed and allowed to settle) and All Follow-Ups (week 1 visit, week 2 visit, month 1 visit combined). The average grade for unique eyes with findings greater than 0 (none) is compared.

    Measured: Change from baseline/dispensing visits, post-dispensing visit and all follow-ups visits

  2. Comparison of Objective Findings - Number of Adverse Events in Unique Eyes

    The primary safety endpoint are the objective findings of the number of adverse events in unique eyes associated with the enfilcon A contact lenses compared with those same findings as associated with the galyfilcon A contact lenses.

    The number of adverse events over the duration of the study was reported for each unique eye (bilateral or unilateral). Observations for adverse events were reported for any occurrence from Baseline through end of month 1 visit.

    Measured: Any occurrence from baseline to 1 month visit

Questions about this trial

What is this clinical trial studying?

A study testing enfilcon A and galyfilcon A in people with Ametropia, run by CooperVision, Inc. at 3 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 10 inclusion and 18 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 5 Oct 2020. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 3 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 29 Apr 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?

Objective Assessment: Ocular Response - Biomicroscopy (time frame: Change from baseline/dispensing visits, post-dispensing visit and all follow-ups visits). The study lists 2 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 5 Oct 2020.
