Design outcomes

Primary

MeasureTime frameDescription
Percentage of Patients With Clinical Success at Month 6Month 6Percentage of patients with clinical success at month 6. Clinical success is defined as the percentage of patients with corneal sensitivity (the capability of the cornea to respond to stimulation) \>= 50 millimeters in all regions of the study eye at month 6 of the Treatment Phase.

Secondary

MeasureTime frameDescription
Change From Baseline in Keratocyte Density in the Anterior Flap of the Eyes at Month 6Baseline, Month 6Change from baseline in keratocyte (specialized cells in the cornea activated after injury or inflammation) density (thickness) in the anterior flap of the eyes (better eye and worse eye) at month 6 of the Treatment Phase. A positive number change from baseline represents an increase in density (improvement). A negative number change from baseline represents a decrease in density (worsening).
Change From Baseline in Goblet Cell Density of the Eyes at Month 6Baseline, Month 6Change from baseline in goblet cell density of the eyes (better eye and worse eye) at month 6 of the Treatment Phase. Goblet cells are special cells in the eye that support a healthy tear film. A positive number change from baseline represents an increase in goblet cells (improvement).

Outcome results

Primary

Percentage of Patients With Clinical Success at Month 6

Percentage of patients with clinical success at month 6. Clinical success is defined as the percentage of patients with corneal sensitivity (the capability of the cornea to respond to stimulation) \>= 50 millimeters in all regions of the study eye at month 6 of the Treatment Phase.

Time frame: Month 6

Population: Modified Intent-to-Treat (mITT). The mITT population included all randomized and treated patients with a study eye having a corneal sensitivity measurement of \< 25 mm in the 3 central regions of the eye on Day 2.

Secondary

Change From Baseline in Goblet Cell Density of the Eyes at Month 6

Change from baseline in goblet cell density of the eyes (better eye and worse eye) at month 6 of the Treatment Phase. Goblet cells are special cells in the eye that support a healthy tear film. A positive number change from baseline represents an increase in goblet cells (improvement).

Time frame: Baseline, Month 6

Population: Intent-to-Treat (ITT). The ITT population includes all patients who started the study (randomized).

A positive number change from baseline represents an increase in density (improvement). A negative number change from baseline represents a decrease in density (worsening).
