EC-104 Intravitreal Implant for the Treatment of Diabetic Macular Edema

This is a prospective, randomized, subject- and evaluator-masked, Phase 2, multicenter study comparing the safety and efficacy of EC-104-6M high-dose (fluocinolone acetonide \[FA\] 0.14 mg) implant and EC-104-4M low-dose (FA 0.092 mg) implant to Ozurdex® (dexamethasone intravitreal (IVT) implant, 0.7 mg) in subjects with diabetic retinopathy (DR) and center-involving diabetic macular edema (DME), with prior suboptimal clinical response to IVT anti-VEGF therapy who have been previously treated with locally administered corticosteroids without a clinically significant rise in intraocular pressure (IOP).
