Brief summary

This was a multi-center, randomized, active-controlled, open-label study. Approximately 24 patients with active, non-infectious intermediate-, posterior-, or panuveitis requiring systemic immunosuppressive therapy were enrolled. Safety, efficacy, and PK assessments occurred at scheduled visits over a 12-week period. Low-molecular-weight non-steroidal immunosuppressive medications were allowed up to the baseline day as long as the dose had not changed in the 3 weeks prior to baseline, except for corticosteroid doses for which might have changed. Patients responding to treatment were offered up to 6 months of extended treatment. Assessments for safety included laboratory safety tests, ECGs, physical exams, ocular exams, vital signs and the monitoring of adverse events. Study participation varied from a minimum of 3 months to a maximum of 9 months.

Detailed description

Approximately 24 patients with active non-infectious uveitis, in at least one eye, requiring intensification of systemic immunosuppressive therapy were enrolled and randomized to receive intravitreal LFG316 or conventional therapy (investigator's discretion). Only one eye (the study eye) were treated with LFG316 and the other eye (fellow eye) were treated at the investigator's discretion.Throughout the study, the fellow eye might have been treated as needed; except that certain systemic medications were prohibited. There was 1 screening and 8 scheduled visits over 85 days for a total of 9 site visits for all patients. At Day 85, patients receiving LFG316 treatment who met the criteria for a 'responder', were offered an additional 6 months of LFG316 treatment on a PRN basis. Additional 3 scheduled visits were attended by LFG316-responder patients during the extension period. However, patients could have unscheduled visits as needed and as determined by the investigator. Safety evaluation and ocular assessments were performed throughout the study duration. Patients in the treatment extension phase, who experienced a flare post their last dose and required treatment, might have received a dose of LFG316. These patients were assessed for a response at their next PRN visit as scheduled by the investigator. Visit frequency was determined by the investigator. If they continued to respond to LFG316 therapy, they might have remained in the PRN treatment arm. They might have received up to 7 additional doses of LFG316 in the PRN period. Throughout the trial LFG316 were not administered more frequently than monthly. Patients in the extension phase, who discontinued treatment prematurely were asked to return approximately 1 month after their last dose. Low molecular weight non-steroidal immunosuppressive medications were allowed up to the baseline day as long as the dose had not changed in the 3 weeks prior to baseline, except for corticosteroid doses which might have changed.
