Background/Objectives: Evaluate outcomes and treatment patterns with 2 mg intravitreal aflibercept injection among patients who completed the phase 3 PANORAMA trial and enrolled in the VOYAGE (ClinicalTrials.gov identifier, NCT04708145; 12 January 2021) long-term extension study. Methods: During VOYAGE, patients were evaluated every 16 weeks and treated with 2 mg intravitreal aflibercept injection as needed depending on ophthalmoscopic examination findings. Those with no history of panretinal photocoagulation (PRP) received aflibercept if their clinician-determined diabetic retinopathy severity scale (DRSS) level was ≥47. Patients with a history of PRP received aflibercept if active neovascularization was present. New or worsening diabetic retinopathy (DR) severity prompted more frequent treatment. Results: 320 patients (1 eye per patient) from 87 sites completed the PANORAMA trial. Of these, 41 patients (13% of PANORAMA completers) from 14 sites (16%) enrolled in VOYAGE after a mean interim period of 33.7 months, and 35 patients (85%) completed study visits through 1 year. At year 1 in VOYAGE, the mean number of anti-vascular endothelial growth factor (VEGF) injections increased from 1.1 per year during the interim period to 3.4 per year and was associated with stabilization or improvement in DRSS level in 81% (26/32) of patients. Mean best-corrected visual acuity (BCVA) remained relatively stable, and mean central subfield thickness (CST) improved by 24.4 μm to 269.5 μm through year 1 of VOYAGE. There were no unexpected safety events. Conclusions: Following a mean of 3 years of routine clinical care with associated declines in DRSS level, CST, and BCVA, stabilization of DRSS level and BCVA with reductions in CST was achieved through year 1 of the VOYAGE extension study, with a concurrent increase in aflibercept dosing frequency.
