Radar des Essais Cliniques

Visual Acuity:

• Best-corrected distance visual acuity (BCDVA) score better than 75 ETDRS letters, or 0.2 LogMAR, or 20/32 Snellen or 0.625 decimal fraction in the affected eye

Ocular Health:

• Ocular drug toxicity less than two weeks ago
• Any active ocular infection (bacterial, viral, fungal or protozoal) or active ocular inflammation in the affected eye.
• History of any ocular surgery (including laser or refractive surgical procedures) in the affected eye within the three months before study enrollment. (An exception to the preceding statement will be allowed if the ocular surgery is considered to be the cause of the PED. Ocular surgery in the affected eye will not be allowed during the study treatment period and elective ocular surgery procedures should not be planned during the duration of the follow-up period unless the patient will be involved in corneal thinning of more than 1/3 corneal stroma, corneal melting or perforation.
• Prior surgical procedure(s) for the treatment of a chronic corneal epitheliopathy (e.g., complete tarsorrhaphy, conjunctival flap, etc.) in the affected eye with the exception of amniotic membrane transplantation. Patients previously treated with amniotic membrane transplantation may only be enrolled two weeks after the membrane has disappeared within the area of the chronic corneal epitheliopathy or corneal ulcer or at least six weeks after the date of the amniotic membrane transplantation procedure. Patients previously treated with Botox (botulinum toxin) injections used to induce pharmacologic blepharoptosis are eligible for enrollment only if the last injection was given at least 90 days prior to enrollment in the study.
• Chronic corneal epitheliopathy in the background of endothelial decompensation that needs corneal graft
• Anticipated need for punctual occlusion during the study treatment period. Patients with punctual occlusion or punctual plugs inserted prior to the study are eligible for enrollment provided that the punctual occlusion is maintained during the study.
• Evidence of corneal ulceration involving the posterior third of the corneal stroma, corneal melting or perforation in the affected eye.
• Presence or history of any ocular or systemic disorder or condition that might hinder the efficacy of the study treatment or its evaluation, could possibly interfere with the interpretation of study results, or could be judged by the investigator to be incompatible with the study visit schedule or conduct (e.g., progressive or degenerative corneal or retinal conditions, uveitis, optic neuritis, poorly controlled diabetes, autoimmune disease, systemic infection, neoplastic diseases).
• Patients with uncontrolled eyelid abnormality that preclude appropriate eyelid closure or including eyelash abnormality

Study Procedures:

• Known hypersensitivity to one of the components of the study or procedural medications (e.g., fluorescein).
• History of drug, medication or alcohol abuse or addiction.
• Use of any investigational agent within 4 weeks of screening visit.
• Participation in another clinical study at the same time as the present study.
• Participants who are pregnant at the time of study enrollment will be excluded; pregnancy is identified according to the patient's self-report /positive βhCG
