Outcome Measures
Primary Outcomes (1)
Subject-Reported Ocular Itching Score
Change from baseline comparison of reproxalap to vehicle for subject-reported ocular itching score from 0 to 212 minutes in the allergen chamber using a 0 -100 millimeter visual analogue scale (0 = none, 100 = severe) was assessed. The least squares mean (standard error) was derived from mixed model repeated measures for change from baseline included itching score as a dependent variable, treatment, period, and interaction of treatment and period as fixed effects.
Efficacy was assessed from 0 to 212 minutes in the allergen chamber.
Secondary Outcomes (2)
Subject-Reported Ocular Tearing Score
Efficacy was assessed from 0 to 212 minutes in the allergen chamber.
Investigator-Assessed Conjunctival Redness Score
Efficacy was assessed from 0 to 210 minutes in the allergen chamber.

- presence of any chronic ocular degenerative condition or ocular inflammation that, in the opinion of the investigator, is likely to worsen over the course of the clinical trial
- diagnosis of moderate-to-severe pinguecula or pterygium (particularly if it results in chronic erythema), Stevens-Johnson Syndrome, ocular cicatricial pemphigoid, mucous membrane pemphigoid, significant conjunctival scarring, chemical burn, herpetic or neurotrophic keratitis, Cryopyrin Associated Periodic Syndrome (CAPS), or keratoconus
