About this study

This is a double-masked, bilateral, randomized, non-dispensing clinical trial. The study lenses will be worn in a bilateral and random fashion using a 5x5 crossover Williams design with 5 lens types and 5 periods. The subjects will wear each pair of lenses for approximately 15 minutes with a 15 minute wash-out between each pair. Two lens types will be fit at the first visit and three lens types will be fit at the second visit. Using a computer-generated randomization scheme, each subject will randomly be assigned to 1 of 10 unique sequences of the 5 lens types. Randomization will be stratified by site.

What is being measured

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

  1. Overall Handling Comparison Between Test 1/Test 2 and Control

    Overall handling was assessed using the Contact Lens User Experience™ (CLUE) questionnaire. CLUE is a validated patient-reported outcomes (PRO) questionnaire to assess patient-experience attributes of soft contact lenses (comfort, vision, handling, and packaging) in a contact-lens wearing population in the US, ages 18-65. Derived CLUE scores using Item Response Theory (IRT) follow a normal distribution with a population average score of 60 (SD 20), where higher scores indicate a more favorable/positive response with a range of 0-120.

    Measured: 15 minutes

Questions about this trial

What is this clinical trial studying?

A study testing etafilcon A Investigational Toric Multifocal Contact Lens in people with Visual Acuity, run by Johnson & Johnson Vision Care, Inc. at 7 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 11 inclusion and 14 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 10 Sep 2020. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 7 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 10 Sep 2020). 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?

Overall Handling Comparison Between Test 1/Test 2 and Control (time frame: 15 minutes). 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 10 Sep 2020.
