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

Stopped early · Phase 3 · Has a placebo group

Conditions studied: Corneal Transplantation, Corneal Graft Rejection

In brief

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.
