Study to Assess the Efficacy and Safety of LX201 for Prevention of Corneal Allograft Rejection Episodes and Graft Failure in Subjects at Increased Immunological Risk

Corneal Diseases Clinical Trial

Official title: A Multi-center, Placebo-Controlled, Randomized, Parallel Group, Dose-Ranging Study to Assess the Efficacy and Safety of LX201 for Prevention of Corneal Allograft Rejection Episodes and Graft Failure Following Penetrating Keratoplasty With LX201 Implantation in Subjects Who Are at Increased Immunological Risk

Status Terminated

Clinical Trial Summary

This was a pivotal trial to determine whether LX201 reduces the likelihood of a graft rejection episode following corneal transplantation in patients at high immunological risk for rejection.

Clinical Trial Description

LX201 was a novel sustained-release silicone implant containing 30% cyclosporine A by weight. LX201 was 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 following penetrating keratoplasty with LX201 implantation. Subjects were to be followed in an outpatient setting for safety and efficacy at 4-6 week intervals for 52 weeks following transplantation surgery.

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. For subjects in the USA and India, if the implant was removed at any time prior to the 3 year safety follow-up, the subject was to have a final safety follow up visit at 3 months post removal. In Germany, the implant was to be removed at Week 52 with a 3-month safety follow-up period after removal. ;
