Summary
This trial will include participants with a certain eye condition called limbal stem cell deficiency. All participants will be given an experimental drug called CSB-001 in one or both of their eyes. The study
Who is the study for?
This trial is for individuals with limbal stem cell deficiency (LSCD), a condition affecting the eyes. Participants will receive CSB-001 Ophthalmic Solution in one or both eyes if they qualify. Specific eligibility criteria are not provided, but typically include having LSCD without other major eye diseases and being able to follow the study protocol.
What is being tested?
The safety and effectiveness of CSB-001 Ophthalmic Solution at 0.1% concentration are being tested on people with LSCD. The study has two main dosing phases separated by a break, followed by an observation phase to monitor long-term effects.
