Downloaded from of 88 1 2 3 4 40 ABSTRACT 5 6 7 8 41 Objectives: To evaluate the comparative effectiveness and safety of intravitreal bevacizumab, 9 10 42 ranibizumab, and aflibercept for patients with choroidal neovascular age-related macular 11 12 43 degeneration (cn-AMD), diabetic macular edema (DME), macular edema due to retinal vein 13 14 44 occlusion (RVO-ME) and myopic choroidal neovascularization (m-CNV). 15 16 For peer review only 17 45 Design: Systematic review and random effects meta-analysis. 18 19 46 Methods: Multiple databases were searched from inception to August 17th, 2017 (MEDLINE, 20 21 47 Embase, Cochrane Central). Eligible head-to-head randomized controlled trials (RCTs) 22 23 24 48 comparing the anti-VEGF drugs in patients aged ≥18 years with the retinal conditions of interest. 25 26 49 Two reviewers independently extracted data and assessed risk of bias using the Cochrane risk-of- 27 28 50 bias tool. 29 30 http://bmjopen.bmj.com/ 31 51 Results: Nineteen RCTs involving 7459 patients with: cn-AMD (n=12), DME (n=3), RVO-ME 32 33 52 (n=2), and m-CNV (n=2) were included. Vision gain was not significantly different in patients 34 35 53 with cn-AMD, DME, RVO-ME, and m-CNV treated with bevacizumab versus ranibizumab. 36 37 54 Similarly, vision gain was not significantly different between cn-AMD patients treated with 38 on September 24, 2021 by guest.

In DME patients treated for 2 years, vision gain was as likely to 41 42 56 be attained with aflibercept as with ranibizumab or bevacizumab; however, in the first year of 43 44 57 treatment, patients treated with aflibercept were more likely to attain vision gain than patients 45 46 47 58 with ranibizumab or bevacizumab. Rates of systemic serious harms were similar among 48 49 59 bevacizumab, ranibizumab, and aflibercept. For cn-AMD patients, compared to monthly 50 51 60 treatment, an as-needed treatment regimen (6-9 injections per year) was associated with a 52 53 54 61 mortality increase of 1.8% (RR: 2.0, [1.2, 3.5], 2 RCTs, 1795 patients) in a post-hoc analysis.
