Multiple Dose Safety and Efficacy of LKA651 in Patients With Diabetic Macular Edema

This study was a 3-arm, parallel group, randomized, patient- and investigator-masked trial planned in 90 patients with Diabetic macular edema (DME). The study consisted of a screening period of 60 days, main study (12 weeks), and an extension period (12 weeks). The study was stratified such that sentinel safety cohorts were first enrolled to test the safety of the combination of LKA651 and Lucentis before proceeding with further patient randomization. After determination of safety from Day 15 data from each sentinel cohort, patients were enrolled into 1 of 3 arms: LKA651 monotherapy, LKA651 plus Lucentis, and Lucentis monotherapy. Every patient was dosed 3 times in 4 week intervals in the treatment phase and was then followed up for an extension phase of an additional 12 weeks during which Lucentis was allowed to be administered as rescue at the discretion of the Investigator. No predefined rescue criteria were outlined as guidance.
