Evaluation of the Efficacy of Topical Ophthalmic Steroids in a Modified Conjunctival Allergen Challenge (CAC) Model
Study Details
Study Description
Brief Summary
The purpose of this study is to evaluate the effectiveness of the modified Conjunctival Allergen Challenge (CAC) and observe how the produced allergic inflammation reacts to treatment with a proven ocular anti-inflammatory medication,
Prednisolone, assessed by the following measures:
-
Ocular itching
-
Conjunctival redness

Phase 4 |
Detailed Description
Prospective, single center, randomized, double-masked, placebo controlled study. Subjects will be randomized to one of the following treatment arms to dose four times per day (QID) for 8 days between Visits 4 and 5.
-
Prednisolone phosphate

Outcome Measures
Primary Outcome Measures
- Ocular Itching Change From Baseline to Day 11 [5 minutes post-CAC]
Ocular itching, as assessed by the participant, was measured on a 4-point scale 5 minutes after the conjunctival allergen challenge (CAC). 0 was best (no itching), and 4 was worst (worst itching).
Secondary Outcome Measures
- Conjunctival Redness Change From Baseline to Day 11 [7 Minutes post-CAC]
Conjunctival Redness, as measured by the investigator, on a 4-point scale 7 minutes after the CAC. 0 was best (no redness), and 4 was worst (most redness)
- Episcleral Redness Change From Baseline to Day 6 [7 minutes post-CAC]
Episcleral redness, as measured by the investigator, on a 4-point scale 7 minutes after the CAC.0 was best (least redness), and 4 was worst (most redness).
- Ciliary Redness Change From Baseline to Day 6 [7 minutes post-CAC]
Ciliary redness, as measured by the investigator, on a 4-point scale 7 minutes after the CAC. 0 was best (least redness), and 4 was worst (most redness).
