A Study of the Efficacy and Safety of Brolucizumab vs. Aflibercept in Patients With Visual Impairment Due to Diabetic Macular Edema — KITE  

Diabetic Macular Edema Clinical Trial

Official title: A Two-Year, Two-Arm, Randomized, Double Masked, Multicenter, Phase III Study Assessing the Efficacy and Safety of Brolucizumab Versus Aflibercept in Adult Patients With Visual Impairment Due to Diabetic Macular Edema

Status Completed

Clinical Trial Summary

This was a Phase III, randomized, double-masked, multi-center, active-controlled, two-arm study designed to evaluate the efficacy and safety of brolucizumab 6 mg compared to the active control, aflibercept 2 mg used per authorized label, in subjects with visual impairment due to diabetic macular edema (DME).

Clinical Trial Description

The study included a screening period of up to 2 weeks to assess eligibility, followed by a double-masked treatment period (Day 1 to Week 96). The baseline visit was defined as Day 1/Visit 1, and end of treatment visit as Visit 27 (Week 96). After the last treatment visit, there was a post-treatment follow-up period from Week 96 to Week 100 and an exit visit at Week 100. Subjects were assigned to one of two treatment arms in a 1:1 ratio: brolucizumab 6 mg/0.05 mL (5 loading doses each administered every 6 weeks (q6w) during loading phase then q12w/q8w during maintenance phase with an option to extend treatment interval by 4 weeks during the second year) or aflibercept 2 mg/0.05 mL (5 loading doses each administered every 4 weeks (q4w) during loading phase then q8w during maintenance phase).

Disease activity assessments (DAAs) were conducted by the masked investigator for both treatment arms at Week 32 and Week 36, i.e., 8 and 12 weeks after the end of the loading phase for subjects receiving brolucizumab, and at Week 48, Week 60 and Week 72 (i.e., every 12 weeks). In the brolucizumab arm, subjects who qualified for q12w during this initial q12w interval continued on a q12w treatment frequency unless disease activity was identified at any of the subsequent DAA visits, in which case subjects were switched to a q8w treatment interval until Week 72.

A one-time disease stability assessment was performed by the masked investigator at Week 72 in both treatment arms with the purpose of evaluating the potential for treatment interval extension by 4 weeks. The subjects in the brolucizumab arm who demonstrated disease stability in the one-time assessment at Week 72 under their current assigned treatment regimen (q12w or q8w) were considered for treatment interval extension. To evaluate the adequacy of the individualized q8w, q12w or q16w treatment intervals in the brolucizumab arm, DAAs were performed at every visit from Week 72 up to and including Week 96 (i.e., every 4 weeks) and subjects had their treatment interval modified accordingly. If after Week 72 disease activity had been identified by the masked investigator at a scheduled treatment visit (according to the subject specific treatment schedule q12w or q16w) the subject was assigned to q8w treatment schedule. ;
