A Phase 2 clinical trial evaluating CSB-001 Ophthalmic Solution 0.1% and Vehicle Control for Neurotrophic Keratitis. Completed, enrolled 131 participants across 48 sites in 2 countries.

Detailed Summary

This study will enroll subjects with stage 2 or 3 neurotrophic keratitis. Subjects will be randomized in a 1:1 ratio to the CSB-001 investigational treatment arm or vehicle control arm. All subjects will dose with the randomized treatment four times daily for 8 weeks (controlled treatment phase). During the controlled treatment phase, subjects will return to the clinic weekly from Day 0 to Week 8, and again at Week 10.
