Resumen:
Purpose: To evaluate 52-week efficacy and safety of a treat-and-extend regimen of intravitreal aflibercept 2 mg on treatment-naive Type 3 neovascularization lesions. Methods: Phase IV, prospective, open-label, single-arm, multicenter trial including patients with untreated Stage I/II Type 3 neovascularization lesions and baseline best-corrected visual acuity between 78 and 23 Early Treatment Diabetic Retinopathy Study letters. Primary endpoint: mean change in best-corrected visual acuity from baseline at 52 weeks. Results: Thirty-two eyes from 32 patients were included (mean +/- SD age: 78.2 +/- 7.7 years, 68.8% females, baseline best-corrected visual acuity: 57.9 +/- 15.4 [Snellen fraction 20/70]). Best-corrected visual acuity increased by 10.5 +/- 15.9 Early Treatment Diabetic Retinopathy Study letters at Week 52 (P= 0.0001). The mean foveal and choroidal thickness decreased by 129.1 +/- 80.1 mu m (P< 0.0001) and 64.3 +/- 96.5 (P= 0.0001), respectively. The proportion of patients with intraretinal/subretinal fluid decreased from 28 (87.5%) at baseline to 3 (11.5%) at Week 52 (P< 0.0001). Pigment epithelial detachment and lesion area showed nonsignificant changes over 52 weeks. The mean number of injections was 8.0 +/- 2.0. Seven (21.9%) patients experienced treatment-related adverse events and two (6.3%) experienced serious adverse events; one (3.1%) ocular serious adverse event requiring treatment withdrawal, endophthalmitis, and one (3.1%) nonocular spontaneously resolved serious adverse event, palpitations. One (3.1%) patient experienced an APTC ATE: nonfatal stroke not related to trial treatment. Conclusion: A treat-and-extend regimen of aflibercept improves visual acuity and retinal edema in eyes with Type 3 neovascularization over 52 weeks with good tolerability.
