Study to Assess LX201 for Prevention of Corneal Allograft Rejection or Graft Failure in Subjects Who Have Experienced One or More Rejection Episodes Following Penetrating Keratoplasty
- Conditions
- Corneal TransplantationCorneal Graft Rejection
- Interventions
- Other: Placebo
- Registration Number
- NCT00447642
- Lead Sponsor
- Lux Biosciences, Inc.
- Brief Summary
This study will evaluate the use of LX201 to prevent future graft rejection episodes and/or graft failure in patients who have undergone corneal transplantation and who have recently experienced a rejection episode due to an immune response.
- Detailed Description
LX201 was a novel sustained-release silicone implant containing 30% cyclosporine A by weight. LX201 is intended for surgical episcleral placement in the eye.
The study was a Phase 2/3, multi-center, placebo-controlled, randomized, parallel-group, dose-ranging study of LX201 for prevention of corneal allograft rejection or graft failure in subjects who have had one or more rejection episodes following penetrating keratoplasty.
After Visit 12 (Week 52), subjects in the USA and India with the implant in the study eye were to be followed for safety at least once per year for a 2 year period or until time of implant removal. In Germany, the implant was to be removed at Week 52 with a 3-month safety follow-up period after removal.

- Currently pregnant or lactating
- Active, extraocular and/or systemic infection requiring the prolonged or chronic use of antimicrobial agents or the presence of active hepatitis A, B or C
- Current malignancy or a history of malignancy (within the previous 5 years) except non-metastatic basal or squamous cell carcinoma of the skin or carcinoma-in-situ of the cervix that has been treated successfully
- Active peptic ulcer disease
