Abstract

Purpose : Anti-VEGFs are the current standard of care in managing patients with diabetic macular edema (DME). However, the most suitable regimen following loading doses remains unclear. We performed a multicenter, single-arm, open-label, prospective, interventional study to investigate the efficacy and safety of aflibercept in a treat-and-extend regimen for patients with DME.

Methods : This phase IIIb/IV study was conducted in five centers in Taiwan. Forty five treatment-naïve DME patients were administered five monthly doses of intravitreal aflibercept (2.0 mg) followed by a treat-and-extend (T&E) regimen with a 4-week interval increment/decrement with the maxima capped at 12 weeks to visual/anatomic stability. The primary efficacy endpoint was the mean change in best-corrected visual acuity (BCVA) as measured by the changes in ETDRS letter score from baseline to Week 52. Mean changes in central retinal thickness (CRT), proportion of subjects who gained ≧ 15 ETDRS letters form baseline to Week 52, and proportion of subjects with ≧ 2-step improvement in DRSS were also examined. Safety assessment included adverse events (AEs), physical examinations, vital signs, and clinical safety laboratory tests.

Results : Mean BCVA was significantly higher at Week 52 (66.6 ± 12.5 letters) than at baseline (58.3 ± 11.9 letters). The improvement in BCVA from baseline to Week 52 was 8.3 letters (p < .0001). Mean CST was significantly lower at Week 52 (296.2 ± 88.9 μm) than at baseline (440.6 ± 126.8 μm, p < .0001). Proportion of subjects who gained at least 3 lines from baseline to Week 52 was 22.2%, while 13.6 % of subjects had at least 2-step improvement in DRSS. Eighty-seven percent (39/45) of patients reached either functional or anatomical disease stability and entered T&E at Week 20, while 88.9 % (40/45) of patients reached longest injection interval of 12 weeks at Week 52. The mean number of injections during the study period was 7.67 ± 1.54. The safety profile demonstrated the injection of aflibercept with T&E regimen was well-tolerated.

Conclusions : The easy-to-follow criteria in this study was applicable in daily practice of DME management with good efficacy and minimum burden. Treat-and-extend regimen of aflibercept demonstrated a favorable visual and anatomical outcomes in DME patients at Week 52 with similar safety profiles as observed before.
