Bottom Line: There was a mean decrease in CST of -50.3 μm (P<0.001) and a mean increase in ETDRS BCVA of +9.2 letters (P<0.001).Fifty percent of subjects were 20/40 or better, and 11.5% of subjects were 20/200 or worse at month 12.Fixed IAI dosing regimen for 12 months demonstrated improved anatomic and vision endpoints in subjects with active exudative AMD.

ABSTRACT

Summary statement: In subjects with active exudative age-related macular degeneration, treating with a fixed intravitreal aflibercept injection dosing regimen for 12 months demonstrated improved anatomic and vision endpoints from baseline.

Purpose: Switching therapies in neovascular age-related macular degeneration (AMD) may offer an advantage for some patients. This study evaluates the efficacy of intravitreal aflibercept injection (IAI) in subjects previously treated with ranibizumab and/or bevacizumab.

Methods: Subjects (n=26) were given monthly 2 mg of IAI for 3 months, followed by 2 mg once in every 2 months for up to 12 months. The mean absolute change from baseline in central subfield thickness (CST) measured by optical coherence tomography and the mean change from baseline in best-corrected visual acuity (BCVA) early treatment in diabetic retinopathy study (ETDRS) letter score were obtained. Additionally, the percentage of subjects who gained or lost ≥15 letters of vision and the percentage of subjects who are 20/40 or better or 20/200 or worse were evaluated.

Results: There was a mean decrease in CST of -50.3 μm (P<0.001) and a mean increase in ETDRS BCVA of +9.2 letters (P<0.001). Twenty-seven percent of subjects experienced a ≥15-letter improvement in visual acuity, and no subject lost ≥3 lines of vision from baseline. Fifty percent of subjects were 20/40 or better, and 11.5% of subjects were 20/200 or worse at month 12.

Conclusion: Fixed IAI dosing regimen for 12 months demonstrated improved anatomic and vision endpoints in subjects with active exudative AMD.

Mentions: The primary outcome was the mean change in CST at month 12, which improved from 304.1 to 253.7 μm at month 12 (−50.3 μm) and was significantly improved from baseline in the study eye at all visits (M12: P<0.001) (Figure 2). The mean BCVA score improved from 56.4 at baseline to 65.6 at month 12 (+9.2 letters) (Figure 3). There was also a significant improvement in BCVA in all follow-up visits except month 1 (M12: P<0.001). The average macular volume improved from 10.3 mm3 at baseline to 9.9 mm3 at month 12 (−0.4 mm3 reduction from baseline). There were statistically significant changes from baseline at all follow-up visits (M12: P=0.038). The mean cube average thickness improved from 286.2 μm at baseline to 274.3 μm at month 12 (−11.9 μm reduction from baseline) and was statistically significant at all follow-up time periods (M12: P=0.038).
