Introduction: To explore the efficacy and safety of intravitreal aflibercept (IVT-AFL) proactive, individualized treat-and-extend (T&E) regimens in exudative age-related macular degeneration (AMD) in the subgroup of patients with polypoidal choroidal vasculopathy (PCV) enrolled in the ALTAIR study. Methods: This was a PCV subgroup analysis of ALTAIR, a 96-week, randomized, open-label, phase 4 study in treatment-naïve patients with exudative AMD in Japan. Following three initial monthly doses, patients received IVT-AFL at week 16 and were randomized 1:1 to T&E regimens with either 2-week (IVT-AFL-2W) or 4-week (IVT-AFL-4W) adjustments. The primary endpoint of ALTAIR was the mean change in best-corrected visual acuity (BCVA) from baseline to week 52. Endpoints were assessed at weeks 52 and 96. Safety analyses were conducted. Results: A total of 90 patients with PCV were included within the full analysis set. From baseline to week 52, mean [standard deviation (SD)] change in BCVA was + 7.5 (14.7) letters and + 8.2 (11.6) letters in the IVT-AFL-2W and IVT-AFL-4W groups, respectively. From baseline to week 96, 91.3% and 90.9% of patients maintained vision in the IVT-AFL-2W and IVT-AFL-4W groups, respectively. From baseline to week 52, mean (SD) change in central retinal thickness was − 153 (177) µm and −112 (122) µm in the IVT-AFL-2W and IVT-AFL-4W groups, respectively. Overall, 51.1% of patients (IVT-AFL-2W, 43.5%; IVT-AFL-4W, 59.1%) achieved a treatment interval of 16 weeks between weeks 16 and 96. The safety profile of IVT-AFL was consistent with previous studies. Conclusion: In treatment-naïve patients with PCV, IVT-AFL administered using two different T&E regimens improved and maintained functional and anatomic outcomes over 96 weeks while minimizing treatment burden. Trial registration: ClinicalTrials.gov identifier, NCT02305238.
