Design outcomes

Primary

MeasureTime frameDescription
Conjunctival Redness Assessed Over 90 Minutes in the Dry Eye ChamberThe efficacy assessment period was assessed during the 90-minute dry eye chamber at Day 2; baseline was Pre-Dose #1 at Day 1.Change from baseline comparison of reproxalap to vehicle for conjunctival redness on a 0 to 4 scale ( 0 = normal, 4 = prominent), where a high score means a worse outcome. The intervention was administered bilaterally. The least squares mean (standard error) was derived from mixed model repeated measures for change from baseline included baseline, site, treatment group, and nominal time point as fixed effects.

Secondary

MeasureTime frameDescription
Schirmer Test Change From Baseline After the First Dose on Day 1The efficacy assessment period was before and after the final dose on Day 1; baseline was Pre-Dose #1 at Day 1.Change from baseline comparison of reproxalap to vehicle for Schirmer test on a millimeter line (0 = none, 35 = maximum), where a shorter length indicates a worse outcome. The least squares mean (standard error) was derived from mixed model repeated measures for change from baseline included baseline and treatment group as fixed effects.

Participant flow

Pre-assignment details

There were 331 randomized subjects, of which 329 were unique (23 in the initial exploratory cohort and 306 in the main cohort). Two subjects in the main cohort were randomized twice by accident and two subjects were randomized but not dosed, making the safety population 327 subjects. The Safety population is presented in the Participant Flow, Baseline Characteristics, and Adverse Events. Efficacy analysis was conducted on subjects in the main cohort (306 subjects, intent-to-treat population).

Outcome results

Primary

Conjunctival Redness Assessed Over 90 Minutes in the Dry Eye Chamber

Change from baseline comparison of reproxalap to vehicle for conjunctival redness on a 0 to 4 scale ( 0 = normal, 4 = prominent), where a high score means a worse outcome. The intervention was administered bilaterally. The least squares mean (standard error) was derived from mixed model repeated measures for change from baseline included baseline, site, treatment group, and nominal time point as fixed effects.

Time frame: The efficacy assessment period was assessed during the 90-minute dry eye chamber at Day 2; baseline was Pre-Dose #1 at Day 1.
