A Study to Evaluate the Efficacy and Safety of 2 Doses of EYE103 Compared With Ranibizumab (0.5 mg) in Participants With DME

EYE-RES-102 is a randomized, double masked pivotal study to evaluate the efficacy and safety of 2 dose levels of EYE103 in comparison with the active control, ranibizumab, in patients with diabetic macular edema (DME) In the first year, all 3 treatment groups will be treated every 4 weeks with either EYE103 or ranibizumab. Beginning at Year 2, the frequency of treatment for participants will shift based on a personalized treatment interval algorithm. Approximately 960 participants will be entered in the study.

EYE-RES-102 is a randomized, double masked pivotal study to evaluate the efficacy and safety of 2 dose levels of EYE103 in comparison with the active control, ranibizumab, in patients with diabetic macular edema (DME) Approximately 960 participants will be entered in the study. Participants will be randomized 1:1:1 to receive low dose EYE103, high dose EYE103, or 0.5 mg ranibizumab, administered via intravitreal injection. In the first year, all 3 treatment groups will be treated every 4 weeks with either EYE103 or ranibizumab. Beginning at Year 2, the frequency of treatment for participants will shift based on a personalized treatment interval (PTI) algorithm. Throughout the 2-year study, subjects will be evaluated every 4 weeks, including measurement of ETDRS BCVA, examination by slit-lamp biomicroscopy, fundoscopy, and SD-OCT. Among other parameters, SD-OCT will be used to measure central subfield thickness (CST) in microns.
