Efficacy, durability, and safety of faricimab with extended dosing up to every 16 weeks in diabetic macular edema: 2-year results from the Japan subgroup of the phase 3 YOSEMITE trial

Abstract

PURPOSE: To evaluate the 2-year efficacy, durability, and safety of faricimab in patients with diabetic macular edema (DME) in the YOSEMITE Japan subgroup. STUDY DESIGN: YOSEMITE/RHINE (NCT03622580/NCT03622593) subgroup analysis: global, multicenter, randomized, double-masked, active-comparator-controlled, phase 3 faricimab trials. METHODS: Patients were randomized 1:1:1 to intravitreal faricimab 6.0 mg every 8 weeks (Q8W) and per treat-and-extend (T&E) dosing, or aflibercept 2.0 mg Q8W. Outcomes were assessed through year 2 for the YOSEMITE Japan subgroup (N = 60) and the pooled YOSEMITE/RHINE global cohort (N = 1891). RESULTS: In the YOSEMITE Japan subgroup, 21, 19, and 20 patients were randomized to faricimab Q8W, faricimab T&E, and aflibercept Q8W, respectively (632, 632, and 627 patients in the pooled YOSEMITE/RHINE cohort). Vision gains and anatomic improvements with faricimab at year 1 were maintained over 2 years and were generally consistent between groups. Mean best-corrected visual acuity changes from baseline at year 2 (weeks 92-100 average) for the YOSEMITE Japan subgroup were +12.5, +9.0, and +5.0 letters in the faricimab Q8W, faricimab T&E and aflibercept Q8W arms, respectively (+10.8, +10.4, and +10.3 letters in the pooled YOSEMITE/RHINE cohort). At week 96, 61.1% of the YOSEMITE Japan subgroup and 78.1% of the pooled YOSEMITE/RHINE cohort were on ≥ Q12W dosing. Faricimab was well-tolerated with a safety profile comparable with aflibercept. CONCLUSION: Faricimab up to Q16W offered durable vision gains and anatomic improvements up to 2 years in patients with DME in the YOSEMITE Japan subgroup. Outcomes were generally consistent with the pooled YOSEMITE/RHINE cohort.
