入选标准

•Men or women aged 18 years or above.
•Participants with PCED in the study eye with the following characteristics:
•a. PCED >= 1.0 mm in greatest diameter
•b. PCED of at least 14 days duration, refractory to one or more conventional nonsurgical treatments (ocular lubricants, discontinuation of preserved topical drops and medications, bandage contact lens) showing no clinical resolution.
•Use of most topical ophthalmic medications (including glaucoma medications) indicated for ocular conditions other than PCED is permitted in the study eye, if the participant has been on a stable dose for at least 30 days and does not expect to have change in dosing regimen throughout the entire duration of the study. Please see exclusion criteria list for exceptions.
•Use of prophylactic topical antibiotics up to four times per day in the study eye is permitted if the participant is already receiving them prior to enrollment.

排除标准

•Contralateral eye with vision of no light perception or anatomic absence of contralateral eye.
•Active ocular infection or inflammation in the study eye as follows:
•a. Bacterial, fungal, or protozoal infection at screening
•b. Active infectious stromal infiltrates or edema at screening
•c. Acute anterior uveitis of grade 2 or greater within 30 days of screening
•d. Acute intermediate uveitis or posterior uveitis within 30 days of screening
•e. Acute inflammation of the sclera or conjunctiva if it is not associated with the PCED
•Corneal epithelial defect associated with stromal thinning greater than 30% (estimated on clinical slit lamp exam) or if associated with stromal infiltrate (corneal haze is acceptable), in the study eye.
•Severe eyelid disease in the study eye, such as:
•a. Mechanical eyelid abnormalities that have direct contact with the PCED (e.g., trichiasis, severe entropion with lid margin keratinization, etc, if in direct contact with the PCED)
•b. Lagophthalmos greater than 2 mm as measured in the clinic
•c. Existing diagnosis of nocturnal lagophthalmos or Parkinsons disease
•d. Inability to fully close eyelids despite voluntary eyelid closure
•e. Severe ectropion with abnormal eyelid-globe congruity (e.g., the lower eyelid does not come into contact with the globe due to severe ectropion)
•Severe end-stage ocular surface disease in the study eye, including but not limited to:
•a. Severe limbal stem cell deficiency, defined as involvement of more than 270 cumulative degrees or more of limbal stem cell deficiency
•b. Keratinization of the bulbar conjunctiva or lid margin
•Use of the following medications and devices within the indicated time window prior to randomization:
•a. Local medications in study eye:
•Any prior use of cenegermin
•Blood-derived eye drops (autologous serum) or other ocular surface re-epithelizing agents, topical anesthetic use by the participant outside of the clinical exam setting, topical insulin, or topical steroids (unless associated with post-operative treatment regimen) within 7 days
•Botox (botulinum toxin) injections for pharmacologic tarsorrhaphy within 90 days
•b. Systemic medications:
•High-dose systemic corticosteroids (greater than 0.5 mg/kg/day) within 30 days
•Any changes in oral medication regimen intended for the treatment of the ocular surface (eg, oral doxycycline) within 30 days, or planned changes during the study period
•Systemic opioid use within 30 days
•Use of any systemic investigational product, ocular investigational product in the study eye, radiation of the head or neck, or systemic chemotherapy within 90 days, or planned to occur during the study period
•c. Devices:
•Use of contact lens (including therapeutic contact lens) within 7 days, or planned use of contact lens during the study period, in the study eye
•Anticipated need for punctal occlusion in the study eye during the study period. Participants with punctal occlusion or punctal plugs inserted prior to the study are eligible for enrolment provided that the punctual occlusion is maintained throughout the study.
•Presence of acute severe systemic disease as follows:
•a. Any acute or active severe systemic inflammatory disease (eg, acute systemic Stevens-Johnson Syndrome, acute systemic GVHD, severe systemic Sjogrens, mucous membrane pemphigoid)
•b. Presence of any systemic disease that may affect ability to participate in the clinical study according to the clinical judgment of the investigator
•Recent surgery or amniotic membrane therapy as follows:
•a. Recent major surgical procedure for the treatment of PCED (eg, conjunctival flap, complete tarsorrhaphy, superficial keratectomy for epithelial defect revision, etc) within 14 days of randomization
•b. Presence of amniotic membrane from AMT for ocular surface indication if not dissolved within area of PCED within 14 days of randomization. Examples include:
•Sutured AMT
•Self-retaining AMT
•Contact lens combined with AMT
•Other AMT treatment for the ocular surface
•c. Partial tarsorrhaphy (temporary or permanent) placed within 14 days of randomization. If a participant is enrolled with partial tarsorrhaphy placed more than 14 days prior to randomization, then the tarsorrhaphy must not be removed for the entire duration of the study.
•Contraception:
•a. Females of child-bearing age (defined as not surgically sterilized or post-menopausal for at least 1 year) are excluded if they meet any 1 of the following conditions:
•Are known to be pregnant
•Have a positive urine pregnancy test at baseline visit
•Are planning to become pregnant during study period
•Are breastfeeding
•Are unwilling to use acceptable form of contraception until 30 days after the study treatment period is complete
•b. Male fertile participants (ie, not surgically sterilized by vasectomy) unwilling to use an acceptable form of contraception (male condom with spermicidal cream or jelly) until 30 days after the study treatment period is complete
•Known active substance abuse or dependency, including but not limited to alcohol, illicit drugs, marijuana, or misuse of prescription medications within 30 days of randomization
