Study Endpoints
Primary Endpoints
Change From Baseline in Best Corrected Visual Acuity (BCVA) (Letters Read) at Week 48 - Study Eye
Baseline, Week 48

BCVA (with spectacles or other visual corrective devices) was assessed using Early Treatment Diabetic Retinopathy Study (ETDRS) testing at 4 meters and reported in letters read correctly. Baseline was defined as the last measurement prior to first treatment. An increase (gain) in letters read from the baseline assessment indicates improvement. One eye (study eye) contributed to the analysis.

Maximum Analyte Serum Concentration [Cmax (ng/mL)]
Day 0 (predose), 6 hr, 24 hr, 72 hr, 168 hr, 336 hr, 504 hr, 672 hr

Serum concentrations at each collection time point were quantitated, where possible, using a validated immunoassay method. These data were analyzed using a noncompartmental pharmacokinetic (PK) method.

Time to Reach Maximum Analyte Serum Concentration [Tmax (h)]
Day 0 (predose), 6 hr, 24 hr, 72 hr, 168 hr, 336 hr, 504 hr, 672 hr

Serum concentrations at each collection time point were quantitated, where possible, using a validated immunoassay method. These data were analyzed using a noncompartmental pharmacokinetic (PK) method.

Area Under the Serum Concentration-time Curve From Time Zero to the Time of the Last Quantifiable Concentration [AUC0-tlast (ng*h/mL)]
Day 0 (predose), 6 hr, 24 hr, 72 hr, 168 hr, 336 hr, 504 hr, 672 hr

Serum concentrations at each collection time point were quantitated, where possible, using a validated immunoassay method. These data were analyzed using a noncompartmental pharmacokinetic (PK) method.

Area Under the Concentration-time Curve From 0 to Infinity [AUC0-inf (ng*h/mL)]
Day 0 (predose), 6 hr, 24 hr, 72 hr, 168 hr, 336 hr, 504 hr, 672 hr

Serum concentrations at each collection time point were quantitated, where possible, using a validated immunoassay method. These data were analyzed using a noncompartmental pharmacokinetic (PK) method.

Elimination Half-life in Serum [t1/2 (h)]
Day 0 (predose), 6 hr, 24 hr, 72 hr, 168 hr, 336 hr, 504 hr, 672 hr

Serum concentrations at each collection time point were quantitated, where possible, using a validated immunoassay method. These data were analyzed using a noncompartmental pharmacokinetic (PK) method.

Concentration of RTH258 Obtained 24 Hours Post Day 0 Injection [C24hr (ng/mL)]
Day 1

Serum concentration at the specified collection time point was quantitated, where possible, using a validated immunoassay method. The data were analyzed using a noncompartmental pharmacokinetic (PK) method.

Concentration of RTH258 Obtained 24 Hours Post Day 56 Injection [C24hr (ng/mL)]
Day 57

Serum concentration at the specified collection time point was quantitated, where possible, using a validated immunoassay method. The data were analyzed using a noncompartmental pharmacokinetic (PK) method.
