Descrizione dettagliata
This is a randomized, double-masked, multi site clinical trial to determine the safety of Ex Vivo CXL of donor corneal tissue in 96 participants who have undergone high-risk penetrating keratoplasty.
Participants will be randomized to receive either a corneal tissue that has been untreated vs. a corneal tissue that has been treated with Photrexa® Viscous & Photrexa® and UV light. The tissue will be prepared by a Corneal Tissue Bank under Current-Good-Tissue-Practice (CGTP) and delivered to the respective institutions for transplantation. Participants will be monitored up to 24 months post-transplantation to assess for adverse events of the randomized tissue.

Descrizione
Inclusion Criteria:
- Age 18 and older
- Willing and able to provide written informed consent
- Willing and able to comply with study assessments for the full duration of the study
- Patients undergoing high-risk penetrating keratoplasty, defined as corneal neovascularization (NV) in 1 or more quadrants ≥2 mm from the limbus or extension of corneal NV to the graft-host junction in a previously failed graft
- Superficial vessels are defined as those within the anterior one-third of the cornea and deep vessels within the posterior two-thirds of the cornea (i.e., deep stroma).
Superficial CNV involving ≤2 quadrants (equivalent to ≤6 clock hours) without deep CNV are classified as mild. CNV with >2 quadrants of superficial vessels (>6 clock hours) or 1 quadrant of deep vessels (>3 clock hours) as severe (36).
Exclusion Criteria:
- History of Stevens-Johnson syndrome or ocular pemphigoid
- Ocular or periocular malignancy
- Non-healing epithelial defect of at least 0.5x0.5 mm in host corneal bed lasting ≥6 weeks preoperatively
- Uncontrolled glaucoma
- Change in topical corticosteroid regimen within 14 days of transplantation
- Use of systemic immunosuppressive for indication other than corneal graft rejection
- Participation in another simultaneous medical investigation or trial
- Pregnancy (positive pregnancy test) or lactating
- Pre-menopausal women not using adequate contraception (Reliable intrauterine devices, hormonal contraception or a spermicide in combination with a barrier method)
- Ocular infection within 30 days prior to study entry.
- Presence of anterior chamber intraocular lens
- Active uveitis within 90 days prior to the study entry.
- No ocular surgery or procedure within 90 days prior to the study entry or concomitant to the study procedure.

Comparatore placebo: Participants Receiving Untreated Cross Linked Corneal Tissue
Participants in this group will receive tissue that has has not been treated with 0.1% riboflavin (Vitamin B2) and 20% dextran (Photrexa® viscous and Photrexa®) without UV light treatment. Participants will be monitored over a period of 24 months. |
Participants are transplanted with corneal donor tissue that has not been treated with the UV light and the 0.1% riboflavin (Vitamin B2) and 20% dextran (Photrexa® Viscous & Photrexa®) without UV light treatment, this is the control group.
