What researchers measure

Primary outcomes

  1. 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.

Secondary outcomes

  1. Schirmer Test Change From Baseline After the First Dose on 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.

    Time frame: The efficacy assessment period was before and after the final dose on Day 1; baseline was Pre-Dose #1 at Day 1.
