Official title
A Randomized, Controlled, Subject- and Evaluator-Masked, Phase 2 Clinical Trial Comparing EC-104 Intravitreal Implant to Ozurdex® for the Treatment of Diabetic Macular Edema (BETTIS-1)
Overview
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).
Detailed description
Approximately 75 subjects who meet entry criteria will be randomized 1:1:1 to EC-104-6M high-dose (FA 0.14 mg) implant or EC-104-4M low-dose (FA 0.092 mg) implant or Ozurdex® (dexamethasone IVT implant 0.7 mg), with the goal of achieving approximately 20 subjects per group with a positive therapeutic response in their study eyes, who are evaluable in the primary endpoint analysis to assess efficacy. Subjects with a positive therapeutic response at Week 4 will be included in the primary and secondary endpoint analyses to assess efficacy for "Time to recurrent disease." Subjects who do not achieve a positive therapeutic response will be classified as suboptimal responders. While suboptimal responders will not be included in the primary and the secondary endpoint analyses to assess efficacy for "Time to recurrent disease," they will remain in the study and will be followed prospectively, with inclusion in the remaining endpoints to assess efficacy and all safety endpoint analyses
