Combination OZURDEX® & EyLea® vs. OZURDEX® Monotherapy in IncompLete-Responders wIth Diabetic Macular Edema

Summary

COLLIDE is a multi-center, open-label, 1:1 randomized study looking at the effects of aflibercept (AFL; 2.0mg) plus OZURDEX (DEX; 0.7mg) implant combination therapy versus DEX monotherapy in phakic or pseudophakic eyes with center-involved DME that have demonstrated prior incomplete response to 3-6 anti-VEGF treatment in 3-9 months. The primary outcome will be 24 week central subfield thickness. Secondary outcomes include the change in ETDRS BCVA letters, number of re-injections and re-injection interval, proportion of eyes with 15- and 10- ETDRS letter gained/lost, proportion of eyes with PDR as per Optos color and FA at the study completion (24+/- 2 weeks) and OCT and OCT angiography biomarkers.
