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.

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
Corneal staining test
Time Frame: (12-week-point)
The degree of staining of the cornea after blue fluorescein staining under the light of cobalt blue using a yellow filter was evaluated according to the Oxford grading system (0 to 5, the higher the worse)
(12-week-point)
Conjunctival staining test
Time Frame: (12-week-point)
The conjunctiva was divided into 6 areas and evaluated after the same staining method according to the Oxford grading system (0 to 3, the higher the worse)
(12-week-point)
Ocular surface disease index (OSDI)
Time Frame: (12-week-point)
The ocular surface was assessed using OSDI scoring questionnaire (0 to 100, the higher the worse)
(12-week-point)
Compliance check
Time Frame: (12-week-point)
Compliance of the drug administration has been check through the subject's self description (0 to 100, the higher the better)
(12-week-point)

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
Corneal staining test
Time Frame: (4-week-point)
The degree of staining of the cornea after blue fluorescein staining under the light of cobalt blue using a yellow filter was evaluated according to the Oxford grading system(0 to 5, the higher the worse)
(4-week-point)
Conjunctival staining test
Time Frame: (4-week-point)
The conjunctiva was divided into 6 areas and evaluated after the same staining method according to the Oxford grading system (0 to 3, the higher the worse)
(4-week-point)
Ocular surface disease indext (OSDI)
Time Frame: (4-week-point)
The ocular surface was assessed using OSDI scoring questionnaire(0 to 100, the higher the worse)
(4-week-point)
IOP (intraocular pressure)
Time Frame: (4- / 12-week-point)
IOP was measured using Goldmann applanation tonometry and measured in mmHg. (numerical)
(4- / 12-week-point)
Tear break up time (TBUT)
Time Frame: (4- / 12-week-point)
The time taken from the last blink to the appearance of a black spot on the cornea after fluorescein dye staining. (second, numerical)
(4- / 12-week-point)
Limbal and bulbar hyperemia
Time Frame: (4- / 12-week-point)
The conjunctival hyperemia was assessed using Efron grading scales (0 to 4, the higher the worse)
(4- / 12-week-point)
