Injection-free subgroup results demonstrated that a single intravitreal dose of 4D-150 without any supplemental anti-VEGF injections resulted in stable mean visual acuity that was equal to or higher than in the standard bimonthly aflibercept control group at all six timepoints through Week 24Single intravitreal 3E10 vg/eye dose resulted in sustained reduction and stabilization of mean central subfield thickness (CST) compared to aflibercept at all timepoints In the 3E10 vg/eye injection-free sub
