Abstract
Purpose: To determine proportion of eyes with neovascular age-related macular degeneration (nAMD) with retinal fluid and/or central subfield thickness (CST) fluctuations and evaluate their impact on best-corrected visual acuity (BCVA) in eyes treated with the Port Delivery System with ranibizumab (PDS) versus monthly intravitreal ranibizumab injections.
Design: Post-hoc analyses of phase 3 Archway trial (NCT03677934).
Participants: Adults with nAMD responsive to anti-vascular endothelial growth factor therapy.
Intervention: 418 patients randomized 3:2 to the PDS (100 mg/mL) with refill-exchanges every 24 weeks (Q24W) or monthly intravitreal ranibizumab (0.5 mg) for 96 weeks.
Outcomes: Proportion of eyes in each treatment arm with subretinal and/or intraretinal fluid (SRF/IRF) overall and in central 1-mm; BCVA changes from baseline by treatment arm and fluid presence/location; proportion of eyes with CST fluctuations from baseline to week 48, week 48 to 96, and baseline to week 96; effects of CST fluctuations on BCVA.
Results: 415 eyes were assessed. In the PDS versus monthly ranibizumab arm, proportion of eyes with SRF/IRF, central SRF, and central IRF were 47.6% versus 50.9%, 29.0% versus 19.2%, and 11.7% versus 12.6% at baseline, and 57.8% versus 56.1%, 21.6% versus 14.8%, and 7.0% versus 8.4% at week 96. BCVA changes from baseline to week 96 were -1.1 letters with the PDS versus -1.4 with monthly ranibizumab in eyes with SRF/IRF, and -1.9 versus -1.8 in eyes with central SRF. In eyes with central IRF, BCVA changes from baseline to week 96 were -2.1 with the PDS versus -6.9 with monthly ranibizumab, respectively (mean BCVA at 96 weeks 68.9 [20/40] versus 64.6 [20/50]). CST fluctuations occurred in 32.1% and 29.7% of PDS versus monthly ranibizumab eyes; corresponding BCVA changes from baseline to week 96 were -2.5 versus -2.6 (mean BCVA at 96 weeks 72.7 [20/35] versus 71.5 [20/38]).
Conclusions: PDS Q24W maintained BCVA to 96 weeks regardless of SRF/IRF, central SRF, central IRF, or CST fluctuations, comparable with monthly ranibizumab, thus supporting the use of the PDS in stabilizing retinal anatomy without the need for monthly treatment in patients with nAMD.
