ClinConnect Summary

This clinical trial is investigating a new treatment for a serious eye infection called bacterial keratitis, which has become resistant to standard antibiotics. The treatment being tested is a special kind of eye drop known as GP-asPNA. The main goal of the study is to see if these eye drops are safe and effective for patients who have this difficult-to-treat infection.

To be eligible for the trial, participants must be at least 18 years old and have been diagnosed with a bacterial keratitis infection that does not respond to regular antibiotics. They should not have any serious immune system issues or other eye infections. If someone joins the study, they can expect to use the eye drops as part of their treatment and attend follow-up visits to monitor their progress. Participation is voluntary, and all candidates must provide informed consent, meaning they fully understand what the trial involves before agreeing to take part.
