Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

A pterygium is a wing-shaped, benign tissue growth which forms on the surface of the conjunctiva and grows towards the cornea. It can eventually lead to vision impairment. The precise cause of pterygium formation is unknown but new blood vessel growth and fibroblastic structures are characteristics of the disease. AG-86893 is an eye drop being developed to treat hyperemia (redness) and growth of the pterygium.

Hypothesis

1. AG-86893 dosed three times daily for 28 consecutive days has an acceptable safety profile as measured by the incidence and severity of adverse events (AEs) compared with vehicle
2. At least 1 concentration of AG-86893 is effective, as measured by the mean change from baseline in conjunctival hyperemia (redness), compared with vehicle

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* Presence of pterygium with associated conjunctival hyperemia (redness) of grade ≥2 as assessed by a central reading center.

Exclusion Criteria

* History or presence of any ocular diseases other than pterygium or its sequelae (after-effects), including neoplasia (uncontrolled overgrowth)
* Diagnosis of ocular hypertension or glaucoma requiring use of intraocular pressure-lowering medication
* Use of contact lenses during the study in the study eye
