Official title
A Prospective, Multicenter, Randomized Controlled Trial to Evaluate the Efficacy and Safety of Amnion Membrane Disc Allograft Versus Standard of Care in Participants With Moderate to Severe Dry Eye Disease
Overview
To evaluate the efficacy of Lyophilized Human Amnion Membrane Disc in reducing corneal epithelial damage as measured by the Lexitas Modified National Eye Institute (NEI) Grading Scale for Corneal Fluorescein Staining.
Detailed description
Dry Eye Disease (DED) is a chronic, progressive inflammatory multifactorial disease of the ocular surface characterized by a loss of homeostasis of the tear film. It is accompanied by ocular symptoms, in which tear film instability and hyperosmolarity, ocular surface inflammation and damage, and neurosensory abnormalities play etiological roles. DED creates a vicious cycle of ocular surface inflammation and damage. Beyond simple 'dryness', DED is recognized as a chronic, potentially progressive condition that can lead to significant visual impairment, corneal scarring, and a diminished quality of life (QoL) comparable to moderate-to-severe angina or dialysis.
While standard therapies (lubricants, anti-inflammatory agents) manage symptoms, many patients suffer from refractory epithelial defects and keratitis. Human Amniotic Membrane (HAM) has been shown to possess anti-inflammatory, anti-scarring, and epithelial-promoting properties. The Human Amniotic Membrane (HAM) is the innermost layer of the placenta. It is uniquely suited for ocular surface reconstruction due to its complex biological scaffold.
Interventions
- Procedure Standard of Care (SOC)
Standard of care is to perform eye cleansing with sterile saline, application of one drop of Ofloxacin prophylactically to eye, application of topical anesthetic, application of bandage lens to eye, application of drops of saline as needed to ensure hydration, taping eye partially shut and continuation of preservative free topical lubricating drops. - Other Lyophilized Amnion Membrane Disc Allograft
Lyophilized Amnion Membrane Disc Allograft derived from donated human tissues.
Primary outcome measures
- Corneal Epithelial Damage [Time frame: 6-8 weeks]
Secondary outcome measures (2)
- Patient Reported Symptoms [Time frame: 6-8 weeks]
- Stability of Tear Film [Time frame: 6-8 weeks]
Eligibility criteria
Inclusion criteria
- 18 years of age or older.

- Participant must be able to follow study instructions, with the intention of completing all required visits
- Participant must agree to attend the study visits required by the protocol.
- Participant must be able and willing to complete follow-up.
- Participant must be willing and able to participate in the informed consent process.
Exclusion criteria
- Presence of persistent corneal epithelial defect or ulcer in either eye
- Presence of active ocular infection in either eye
- Presence of ocular inflammation that is not related to keratoconjunctivitis sicca, e.g., allergy, severe blepharitis
- Presence of other corneal disorder(s) that give rise to reduced corneal sensitivity, such as recurrent herpes keratitis
- Presence of corneal diseases other than dry eye that can disturb the pre-corneal tear film such as epithelial basement membrane dystrophy (EBMD)
- Contact lens wear
- History of recent ocular surgery/trauma, which could affect corneal sensitivity, e.g., corneal transplantation, LASIK
- Presence of cicatricial ocular surface diseases
- History of procedures listed in 6.7.1 within the specified washout period
