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

The primary objective of the study is to establish the ocular safety and tolerability, and systemic safety of 3 different concentrations of preservative-free PHMB in healthy subjects. Safety and tolerability will be compared to those of a placebo.The PHMB bioavailability in plasma will also be assessed

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
Time Frame
Number of Subjects With Dose-limiting Adverse Events
Time Frame: up to 21 days from date of randomization
up to 21 days from date of randomization

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
Time Frame
Plasma Concentration of PHMB
Time Frame: Day14
Day14

Other Outcome Measures

Other Outcome Measures

For clinical trials, a planned measurement described in the protocol that is used to determine the effect of an intervention/treatment on participants. For observational studies, a measurement or observation that is used to describe patterns of diseases or traits, or associations with exposures, risk factors, or treatment. Types of outcome measures include primary outcome measure and secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Systolic Blood Pressure
Time Frame: Baseline and Day 14
Change from baseline systolic blood pressure
Baseline and Day 14
Visual Acuity
Time Frame: Baseline and Day 14
Change from baseline Visual acuity. Best corrected visual acuity was reported in decimal fraction. A decrease of visual acuity during treatment was considered a negative safety outcome.
Baseline and Day 14
Ocular Surface Disease Index-OSDI
Time Frame: Baseline and Day 14
Change from baseline OSDI at D 14. Score range was betwwen 0-100. An increase of OSDI values with treatment represent a negative outcome.
Baseline and Day 14
Conjunctival Examination
Time Frame: Baseline and Day 14
Change from baseline conjunctival staining at Day 14. Staining with lissamine green was used. The density of staining was graded with the Oxford Score. Score range was between 0-15. An increase in the score after treatment represent a negative outcome
