Pivotal Trial
Summary
This trial will study if a drug called RGN-259 is safe and effective in treating a condition called Neurotrophic Keratopathy (NK).
Who is the study for?
Adults with stage 2 or 3 neurotrophic keratopathy (NK) in one eye, confirmed not to be just superficial damage. They must have reduced corneal sensitivity and a specific level of vision impairment. Participants need to agree to contraception use and can't have lid abnormalities, active infections/inflammation unrelated to NK, recent ocular surgery, or conditions that might affect the study's outcome.
What is being tested?
The trial is testing RGN-259 ophthalmic solution against a placebo for treating NK. The goal is to see if RGN-259 is safe and works better than a placebo in healing the eye condition.
What are the potential side effects?
While specific side effects are not listed here, potential risks may include typical reactions related to ophthalmic solutions such as eye irritation, discomfort, redness, or allergic responses.
