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.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.

Enrollment (Actual)

Enrollment

97

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.

Ages Eligible for Study

18 years to 39 years (Adult)

Description

Inclusion Criteria:

  • The subject must be at least 18 and less than or equal to 39 years of age and have a need for vision correction in both eyes.
  • The subject must require a lens power between -1.00 to -6.00D and have no more than 1.00D of corneal cylinder.
  • The subject, based on his/her knowledge, must be in good general health.
  • The subject must be able and willing to adhere to the instructions set forth in this protocol and complete all specified evaluations.
  • Subject must be a current adapted daily wearer of soft contact lenses with at least 6 months of CL wear.
  • Subject must agree to wear their contact lenses in both eyes on a daily wear schedule for at least 8 hours per day every day during the study.
  • Subject must be willing and able to use only the care systems and lubricating drops provided for the study during the 4 week period.
  • The subject must read, indicate understanding of and sign the Informed Consent Form.

Exclusion Criteria:

  • The subject is a rigid gas permeable (RGP) or daily disposable lens wearer.
  • The presence of clinically significant (grade 3 or 4) anterior segment abnormalities; inflammations such as iritis; or any infection of the eye, lids or associated structures.
  • The presence of ocular or systemic disease or need for medication which might interfere with contact lens wear or which would cause the lenses to be removed more than twice a day. (i.e., Sjogren's syndrome, type II diabetes, etc.)

  • Slit lamp findings that would contraindicate contact lens wear such as:

    • pathological dry eye or associated findings
    • pterygium or corneal scars within the visual axis
    • neovascularization equal to or greater than 1mm in from the limbus
    • history of giant papillary conjunctivitis (GPC) worse than grade 2
    • anterior uveitis or iritis (past or present)
    • seborrhoeic eczema
    • seborrhoeic conjunctivitis
  • A history of recurrent erosions, corneal infiltrates, corneal ulcer or fungal infections.
  • A known history of corneal hypoesthesia (reduced corneal sensitivity).
  • Contact lens snellen visual acuities (VA) worse than 20/30.
  • Aphakia, keratoconus or a highly irregular cornea.
  • Current pregnancy or lactation (to the best of the subject's knowledge)
  • Any active participation in another clinical study at any time during this study.

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
Lens Comfort
Time Frame: 1-week, 2- weeks
>0 = comfortable, <0 = uncomfortable; a weighted combined score calculated from individual comfort-related questions was used to derive comfort outcomes.
1-week, 2- weeks
Comfort Symptoms
Time Frame: 1-week, 2-weeks
A weighted combined score calculated from individual comfort-related questions was used to derive comfort outcomes. >0 = comfortable, <0 = uncomfortable
1-week, 2-weeks

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
Overall Corneal Staining
Time Frame: 2 weeks
Measured for 5 zones of the cornea (superior, nasal, central, inferior, temporal)on a 0 to 3 grade scale (NEI 0-3 scale). Grade 0 = Normal/ grade 1 = mild, superficial stippling/ grade 2 = moderate, punctate staining including superficial abrasion of the cornea/ grade 3 = severe, abrasion or corneal erosion, deep corneal abrasion or recurrent erosion.

Study Major Dates

Study Start

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
August 1, 2007

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.

Study Completion (Actual)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit).
