Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

In this 3-treatment, 3-period, 6-sequence crossover study, each participant will wear all 3 products in randomized order, 1 product at a time, with a washout period of up to 7 days between treatment periods. Lenses will be collected for ex-vivo lubricity analysis. The ex-vivo lubricity analysis will be conducted under a separate non-clinical protocol.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Average Coefficient of Friction of Worn Lenses at 16 Hours
Time Frame: Day 1, Hour 16, each product
Worn contact lenses were removed from the participant's eye and the coefficient of friction was measured by the inclined plane method. A lower coefficient of friction may indicate higher contact lens lubricity. The ex-vivo lubricity was carried out on one lens (one eye) only.
Day 1, Hour 16, each product

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Average Coefficient of Friction of Unworn Lenses
Time Frame: Day 1 (each product)
Unworn contact lenses were removed from the commercial packaging and the coefficient of friction of the unworn lenses was measured by the inclined plane method. A lower coefficient of friction may indicate higher contact lens lubricity.
Day 1 (each product)
