• Current uveitis therapy must conform to one of the following:
• Prednisone monotherapy at a dose of = 10 mg/day (or equivalent) for = 2 weeks prior to randomization
• Have received = 2 injections of corticosteroid (intravitreal or periocular) for control of disease within the past 8 months, but not within 2 weeks of randomization; subjects may also be receiving systemic corticosteroid therapy

Primary Outcome Measures
NameTimeMethod
<br> Main Objective: The objective of this study is to assess the safety and efficacy of LX211 as<br> therapy in subjects with active sight-threatening, non-infectious intermediate-,<br> anterior and intermediate-, posterior-, or pan- uveitis.<br> ;Secondary Objective: None.;<br> Primary end point(s): The primary endpoint is the mean change from baseline in graded vitreous haze after 16 weeks of therapy or at time of rescue, it earlier. Subjects who experience either an increase of at least 1 grade from baseline at Visit 3 or show no improvement from baseline by Visit 4 are to receive rescue therapy.<br><br> If statistical significance is achieved for vitreous haze at 16 weeks, then mean change from baseline in graded vitreous haze after 24 weeks of therapy or at time of rescue, if earlier, will also be analyzed as a primary endpoint.<br>
