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.

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

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
Ocular Redness as Measured by the Investigator Using the Ora Calibra™ Ocular Hyperemia Scale
Time Frame: 0 (predose), 5, 15, 30, 60, 90, 120, 180, and 240 minutes postdose on Day 1
Ocular redness using the Ora Calibra Ocular Hyperemia Scale was scored by the Investigator using the following scale (allowing half unit increments): 0=None; 1.0=Mild-Slightly dilated blood vessels, color of vessels is typically pink, can be quadrantal; 2.0=Moderate-More apparent dilation of blood vessels, vessel color is more intense (redder), involves the majority of the vessel bed; 3.0=Severe-Numerous and obvious dilated blood vessels, in the absence of chemosis the color is deep red, may be less red or pink in presence of chemosis, is not quadrantic; 4.0=Extremely Severe-Large, numerous, dilated blood vessels characterized by unusually severe deep red color, regardless of grade of chemosis, which involves the entire vessel bed. A lower score is indicative of less redness.
0 (predose), 5, 15, 30, 60, 90, 120, 180, and 240 minutes postdose on Day 1

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
Ocular Redness as Measured by the Participant
Time Frame: Day 1 to Day 15; Day 15 to Day 29; Day 29 to Day 36
Ocular redness was scored daily pre-dose and post-dose on Days 1 to 29 and scored daily on Days 30 to 36 by the participant using a 0 to 4 unit scale (not allowing half unit increments). A lower score was indicative of less redness. The LOCF method used for this Secondary Outcome Measure was for imputing missing daily post-dose mean scores for entire days. If ≥1 score was provided for a day, imputation was not done. Imputation was done within the dosing period and separately within the follow-up period. The average (mean) daily pre-dose and post-dose scores for the dosing period Day 1 to Day 15 and dosing period Day 15 to Day 29, and the average (mean) daily score for the follow-up period Day 29 to Day 36 are reported.
Day 1 to Day 15; Day 15 to Day 29; Day 29 to Day 36
Change From Predose Ocular Redness Score as Measured by the Investigator Using the Ora Calibra Ocular Hyperemia Scale
Time Frame: 0 (predose), 1, 360, and 480 minutes (min) postdose on Day 1 and 0 (predose), 1, and 5 min postdose on Days 15 and 29
Ocular redness using the Ora Calibra Ocular Hyperemia Scale was scored by the Investigator using the following scale (allowing half unit increments): 0=None; 1.0=Mild-Slightly dilated blood vessels, color of vessels is typically pink, can be quadrantal; 2.0=Moderate-More apparent dilation of blood vessels, vessel color is more intense (redder), involves the majority of the vessel bed; 3.0=Severe-Numerous and obvious dilated blood vessels, in the absence of chemosis the color is deep red, may be less red or pink in presence of chemosis, is not quadrantic; 4.0=Extremely Severe-Large, numerous, dilated blood vessels characterized by unusually severe deep red color, regardless of grade of chemosis, which involves the entire vessel bed. A lower score is indicative of less redness.
0 (predose), 1, 360, and 480 minutes (min) postdose on Day 1 and 0 (predose), 1, and 5 min postdose on Days 15 and 29
