Study to Evaluate the Safety and Efficacy of CSB-001 Ophthalmic Solution 0.1% in Subjects With Limbal Stem Cell Deficiency

Description

This study will enroll subjects with qualifying limbal stem cell deficiency (LSCD). All subjects will receive CSB-001 investigational drug in either one or both study eyes. The study is comprised of two identical phases (Dosing Phase I and II) of test article dosing separated by a 31- to 40-day period, the Dosing Holiday, where no test article is administered. Dosing Phase II is followed by an observational, noninterventional phase (Observation Phase).
