Longer treatment intervals possible with 8 mg aflibercept in DME

Posted on

Data from the ongoing pivotal PHOTON trial presented at AAO 2022 demonstrated that vision was maintained at longer injection intervals with 8 mg intravitreal aflibercept in patients with diabetic macular edema.

In this multi-center randomized, double-masked study, patients with DME were randomized 1:2:1 to receive aflibercept 2 mg every 8 weeks after 5 initial monthly injections (n = 167), aflibercept 8 mg every 12 weeks after 3 initial injections (n = 328), or aflibercept 8 mg every 16 weeks after 3 initial monthly injections (n = 163).

At Week 48, both the aflibercept 8 mg groups showed non-inferior BCVA compared to the aflibercept 2 mg every 8 weeks group.

All groups demonstrated “a robust increase in visual acuity,” according to presenter David M. Brown, MD, and most patients receiving 8 mg aflibercept maintained randomized intervals through Week 48, with 93% of 8 mg patients maintaining dosing intervals of ≥12 weeks.

Dr Brown said that ocular adverse events through Week 48 were in line with other studies and there were no reported cases of endophthalmitis or occlusive retinal vasculitis.
