Proof of Concept Study to Evaluate Safety and Efficacy of LME636 in the Treatment of Acute Anterior Uveitis

Response was defined as a two-step decrease or more from baseline in Anterior Chamber (AC) Cell Grade as per Standardization of Uveitis Nomenclature (SUN). Baseline was defined as the measurement taken before drug administration on Day 1. Subjects receiving rescue treatment on or before Day 15 were considered non-responders. Only one eye contributed to the analysis.

Visual Acuity (VA) with the subject's best spectacles or other visual corrective devices was measured using an Early Treatment of Diabetic Retinopathy Study (ETDRS) or Snellen visual acuity chart and reported in letters read correctly. An increase (gain) in letters read indicates improvement. Only one eye contributed to the analysis.

IOP (fluid pressure inside the eye) was assessed using Goldmann applanation tonometry or Tonopen and reported in millimeters mercury (mmHg). A higher IOP can be a greater risk factor for developing glaucoma or glaucoma progression (leading to optic nerve damage). Only one eye contributed to the analysis.

Slit-lamp biomicroscopy (examination) was performed to evaluate the anterior segment of the eye, including lids/lashes, conjunctiva, cornea, anterior chamber (cells and flare), iris, and lens. Ocular signs were categorized as Aqueous Flare, Aqueous Inflammatory Cell Grade, Keratic Precipitates, Lens, Limbal Injection, Status of Lens, Peripheral Anterior Synechia, and Posterior Synechia. An increase indicates worsening. Only one eye contributed to the analysis.

The dilated fundus examination was performed to evaluate the health of the vitreous, optic disc, retinal vessels, macula, and retinal periphery. An increase indicates worsening. Only one eye contributed to the analysis.

IOP was assessed using Goldmann applanation tonometry or Tonopen and reported in mmHg. A higher IOP can be a greater risk factor for developing glaucoma or glaucoma progression (leading to optic nerve damage). Only one eye contributed to the analysis.

Visual Acuity (VA) was measured with the participant's best spectacles or other visual corrective device in place using an ETDRS or Snellen visual acuity chart. Improvement of BCVA was defined as an increase (gain) in letters read from the baseline assessment. Only one eye contributed to the analysis.

Time-to-Response was defined as the number of days from baseline to the first scheduled visit when a two-step decrease or more from baseline in AC Cell Grade (as per SUN) was observed. Time-to-Response is reported as number of subjects presenting time-to-response by visit. Only one eye contributed to the analysis.

Use of rescue treatment is presented as the number of subjects with first use of rescue treatment by visit. Subjects receiving rescue medication were not considered withdrawn and the collection of data continued after discontinuation of study treatment. Only one eye contributed to the analysis.

Serum concentrations at each collection time point were quantitated, where possible, using a validated immunoassay method. Concentrations below the limit of quantification (BLQ), defined as 0.25 ng/mL, were reported as NA with no imputation for missing data.

Serum samples were collected and assessed for anti-LME636 antibodies. Samples collected from subjects in the LME636 dose group were analyzed for anti-LME636 antibodies. For subjects in the dexamethasone group, only the samples collected on Day 1 (ie, prior to the start of treatment) were analyzed for anti-LME636 antibodies.
