Study Summary

Stage 1: Single Ascending Dose, Safety, Tolerability and Pharmacokinetics (n=24) Stage 2: Multiple Dose, Safety and Efficacy Study with 28-day Dosing and 5 months Followup (n=51)

Primary Outcome

The primary efficacy variable is the change from baseline (Day 1) in severity grade of pterygium vascularity at Week 4. Pterygium vascularity intensity is based on color coordinates as measured by digital image analysis of pterygium photographs. The quantitative analysis of photographs using a 5-point Pterygium Hyperemia Grading Scale (0 = absent, 1 = trace, 2 = mild, 3 = moderate, 4 = severe) will be conducted at an independent image reading center.
