Safety,Tolerability and Efficacy of Intravitreal LFG316 in Patients With Active Non-infectious Intermediate-, posterior-or Panuveitis ,

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.

Key Inclusion Criteria:

- Male or female patients 18 years or older

- Active NIU, in at least one eye, as defined below, in patients requiring
intensification of systemic immunosuppressive therapy;

excluded)

- Patients with a flare and at the time of the enrollment on systemic corticosteroid or
non-steroidal immunosuppressants had their therapy tapered or stopped, respectively,
at the time of intravitreal LFG316 administration.

study eye.

- For female patients, must not be pregnant or lactating and must, unless
post-menopausal, use effective contraception.

- Ability to provide informed consent and comply with the protocol.

Key Exclusion Criteria:

experimental drug

- Any biologic immunosuppressive agent given via intravitreal, intravenous or
subcutaneous route within 4-12 months depending on the agent.

- History of infectious uveitis or endophthalmitis in either eye.

- History of retinal detachment

- Any intraocular surgery, intravitreal injection, periocular injection, or laser
photocoagulation to the study eye within 90 days prior to dosing.

- In the study eye, cataract expected to interfere with study conduct or require surgery
during the study.
