Study of Lacripep Eye Drops to Treat Stage 1 Neurotrophic Keratitis Evaluating Safety and Effectiveness in Adults

What this Trial Is About

Researchers are evaluating the safety and effectiveness of Lacripep 4 M Ophthalmic Solution in people with Stage 1 neurotrophic keratitis NK, a condition affecting the cornea. This Phase 2 study compares Lacripep to a vehicle ophthalmic solution to see how each affects the eye surface, vision, corneal sensitivity, and quality of life. The trial involves about 54 participants and includes detailed eye image assessments by a central reading center to ensure objective results. Participants will first undergo a 2-week run-in period using the vehicle ophthalmic solution openly. Then, at the baseline visit, they are randomly assigned to receive either Lacripep 4 M or the vehicle solution. Both treatments are applied three times daily to both eyes for 8 weeks, with clinic visits at weeks 2, 4, and 8. After this, all participants enter a 4-week open-label phase where everyone receives Lacripep, allowing comparison of shorter and longer treatment durations. During the study, participants will have regular clinic visits for eye exams and assessments to monitor safety and effects on vision and corneal health. Researchers will measure the primary efficacy from baseline to week 8 and continue safety monitoring through week 12. The study includes checks on visual acuity, corneal sensitivity, and intraocular pressure, along with quality-of-life evaluations. Overall participation lasts about 12 weeks, including both masked and open-label treatment phases.
