Trial Outcomes & Findings for The TRANQUILITY Trial: Clinical Trial to Assess the Efficacy and Safety in Subjects With Dry Eye Disease (NCT NCT04674358)

NCT ID: NCT04674358

Last Updated: 2025-03-19

Results Overview

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.

Participant Flow

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).

PRIMARY outcome

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

Population: Intent-to-treat population with observed data only

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 outcome

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

Population: Intent-to-treat population with observed data only

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.

Population: Intent-to-treat population with observed data only

Change from baseline comparison of reproxalap to vehicle for conjunctival redness on a 0 to 255 scale ( 0 = none, 255 = maximum), where a high score means a worse outcome.
