PURPOSE:To evaluate efficacy and safety of efdamrofusp alfa compared with aflibercept in neovascular age-related macular degeneration (nAMD).
DESIGN:Randomized, double-masked, multicenter, active-controlled, non-inferiority phase 2 study PARTICIPANTS: A total of 231 treatment-naïve and previously treated participants with active choroidal neovascularization secondary to nAMD were enrolled.
METHODS:Eligible participants were randomized (1:1:1) to 2 mg efdamrofusp alfa, 4 mg efdamrofusp alfa or 2 mg aflibercept groups. Participants in all groups received three initial monthly loading doses, followed by treatment every 8 weeks with assessment every 4 weeks up to week 52.
MAIN OUTCOME MEASURES:The primary endpoint was the mean BCVA change from baseline to week 36. The pre-specified noninferiority margin was set as -5 letters (80% CI).
RESULTS:Each treatment group included 77 participants. The mean BCVA changes from baseline to week 36 for 2 mg efdamrofusp alfa, 4 mg efdamrofusp alfa and aflibercept groups were +10.6, +11.4, +12.0 letters, respectively; Least Squares (LS) mean difference were -1.4 (80% CI: -3.5 to 0.7) between 2 mg efdamrofusp alfa and aflibercept, and -0.6 (80% CI: -2.7 to 1.6) between 4 mg efdamrofusp alfa and aflibercept. Mean central retinal thickness changes were consistent across groups. Adverse event rate was comparable among the groups.
CONCLUSIONS:Efdamrofusp alfa demonstrated noninferiority to aflibercept in BCVA improvement, accompanied by a similar safety profile.
