Summary

The purpose of this study is to evaluate the efficacy and safety of Nexagon® in subjects with persistent corneal epithelial defects (PED) resulting from corneal epithelial debridement during diabetic vitrectomy surgery, HSV keratitis, HZV keratitis, corneal burns, post-PRK, or post-corneal transplant surgery.

Detailed description

The purpose of this prospective, randomized, double-masked, vehicle-controlled, dose-escalation study is to evaluate the efficacy and safety of Nexagon® in subjects with persistent corneal epithelial defects (PED) resulting from corneal epithelial debridement during diabetic vitrectomy surgery, HSV keratitis, HZV keratitis, corneal burns, post-PRK, or post-corneal transplant surgery. In general, traditional therapy of PED consists of aggressive lubrication with preservative-free artificial tears and ointments, the use of bandage soft contact lenses, pressure patching, punctal plugging, and the surgical closure of the eyelids. Unfortunately, the success rates with these conventional treatment modalities are varied, and overall, disappointingly low. As such, much research is currently being directed at finding better treatments for PED. Nexagon® is a novel therapeutic agent that has been shown to be effective in treating skin lesions, and it has been shown in animal studies and in preliminary human studies to be safe and efficacious in treating PED.

Conditions

• Persistent Corneal Epithelial Defects

Interventions

Type	Name	Description
DRUG	Nexagon	There will be 3 groups of patients with persistent epithelial defects, treated in a dose-escalation fashion from 1µg to 3µg to 10 µg. Each group will consist of 18 patients randomized to Nexagon and 6 patients randomized to placebo only.
DRUG	Vehicle only	There will be 3 groups of patients with persistent epithelial defects, treated in a dose-escalation fashion from 1µg to 3µg to 10 µg. Each group will consist of 18 patients randomized to Nexagon and 6 patients randomized to placebo only.
