Study summary

The purpose of this study is to evaluate two investigational ophthalmic solutions for reduction in ocular redness in subjects with allergic conjunctivitis.

Read the detailed description

Eligible subjects attended 8 study visits, 5 of which included a 3-hour period of ragweed exposure in an Environmental Exposure Chamber. At the sixth visit, subjects received study product and began dosing for up to 9 days. The final visit was the final day of dosing. Participation in this study lasted up to 68 days.

What researchers measure

Primary outcomes

  1. Mean Change From Baseline in Ocular Redness, Area Under the Curve From Time Zero to Hour 10 [AUC (0-10)] at Day 7

    Ocular redness ratings were collected for nasal and temporal areas of each eye and assessed by investigational center staff using a visual scale (ie, scored by comparing the subject's eye with a series of photographs) and graded on a scale from 0 (none) to 4 (extremely severe), 0.5 unit steps permitted. AUC was calculated using the trapezoidal rule with unequal intervals as determined by the assessment time points. Change was calculated as AUC(0-10)\[Day 7\] - AUC(0-10) \[Baseline\]. Both eyes contributed to the analysis.

    Time frame: 0.0, 0.25, 0.50, 1.0, 1.5, 2.0, 2.5, 3.0, 3.5, 4.0, 5.0, 6.0, 7.0, 8.0, 9.0, and 10.0 hours on Days 1 (baseline) and 7

Secondary outcomes

  1. Mean Change From Baseline in Ocular Itching, Area Under the Curve From Time Zero to Hour 10 [AUC (0-10)] at Day 7

    Ocular itching was assessed by the subject with both eyes rated together and scored on a scale from 0 (none) to 4 (incapacitating itch with irresistible urge to rub). AUC was calculated using the trapezoidal rule with unequal intervals as determined by the assessment time points. Change was calculated as AUC(0-10)\[Day 7\] - AUC(0-10) \[Baseline\].

    Time frame: 0.0, 0.25, 0.50, 1.0, 1.5, 2.0, 2.5, 3.0, 3.5, 4.0, 5.0, 6.0, 7.0, 8.0, 9.0, and 10.0 hours on Days 1 (baseline) and 7
