Diabetic macular edema (DME) is a major cause of vision loss for people with diabetes. Intravitreal anti-vascular endothelial growth factor (VEGF) therapy is the standard of care for DME; however, there is an unmet need for new strategies that address the multifactorial nature of DME, reduce treatment burden, and optimize patient outcomes. Angiopoietin-2 and VEGF-A synergistically drive vascular instability in DME; therefore, dual pathway inhibition with faricimab, the first bispecific antibody designed for intraocular use, may promote vascular stability and durable efficacy beyond current anti-VEGF therapies. YOSEMITE (NCT03622580) and RHINE (NCT03622593) were randomized, double-masked, active comparator-controlled, phase 3 trials designed to assess the efficacy, durability, and safety of faricimab in patients with DME (YOSEMITE, N = 940; RHINE, N = 951) . Patients were randomized 1:1:1 to faricimab 6.0 mg every 8 weeks (Q8W) after 6 initial every-4-week (Q4W) doses, faricimab 6.0 mg per personalized treatment interval (PTI) after 4 initial Q4W doses, or aflibercept 2.0 mg Q8W after 5 initial Q4W doses. The PTI algorithm was a protocol-driven treat-and-extend regimen, with dosing intervals extended, maintained, or reduced (from Q4W up to every 16 weeks [Q16W]) based on prespecified vision and anatomic criteria. Efficacy and safety endpoints were assessed at Q4W study visits through week 100. At 1 year, faricimab Q8W or per PTI offered durable vision gains that were noninferior to aflibercept Q8W and were achieved with Q16W dosing in &gt; 50% of patients in the PTI arms. Faricimab Q8W or per PTI demonstrated anatomic improvements versus aflibercept Q8W and was well tolerated, with low rates of intraocular inflammation. Year 2 results from YOSEMITE/RHINE will be presented at the meeting, and will examine whether early vision gains, anatomic improvements, and extended (up to Q16W) dosing with faricimab are maintained over 2 years.
