January 18, 2024, Osaka, Japan – Santen Pharmaceutical Co., Ltd. (head office: Osaka, Japan; hereinafter, Santen) and Bayer Yakuhin, Ltd. (head office: Osaka, Japan; hereafter, Bayer Yakuhin) announced today that, following an application by Bayer Yakuhin, they had obtained regulatory approval from the Ministry of Health, Labour, and Welfare (MHLW) for ophthalmic Vascular Endothelial Growth Factor (VEGF) inhibitor "Eylea®8mg Intravitreal Injection 114.3 mg/mL" (aflibercept [recombinant] intravitreal injection; hereafter, Eylea®8mg) for the treatment of neovascular (wet) age-related macular degeneration (nAMD) and diabetic macular edema (DME).
The approval is based on results from the PULSAR clinical trial in nAMD and the PHOTON clinical trial in DME. Both studies met their primary endpoint of non-inferior best corrected visual acuity (BCVA) changes with Eylea®8mg with 12- or 16-week dosing regimens compared to Eylea® (aflibercept 2 mg) with a fixed 8-week treatment interval at week 48, following initial monthly doses. In these studies, the safety profile of Eylea®8mg was consistent with the safety profile of Eylea® (aflibercept 2 mg). This would mean a considerable reduction in disease burden for patients while providing sustained disease control.
Eylea®8mg will be distributed in Japan by Santen, with manufacturing and marketing authorization held by Bayer Yakuhin. Promotional activities for this drug will be conducted jointly by both companies.

About PULSAR and PHOTON
PULSAR and PHOTON are randomized, double-masked, active-controlled pivotal trials. Both trials were conducted in multiple centers globally with similar designs and endpoints. The Phase III PULSAR trial in nAMD and Phase II/III PHOTON trial in DME evaluated the efficacy and safety of aflibercept 8 mg with 12- and 16-week dosing regimens versus Eylea®(aflibercept 2 mg) dosed every 8 weeks, following initial monthly doses, with the primary endpoint of non-inferiority in terms of best corrected visual acuity (BCVA) changes at week 48. Patients in both clinical trials were randomized at baseline to the three different arms. Across both studies, 1,164 patients were treated with aflibercept 8 mg. All patients in the aflibercept 8 mg arms were continuously evaluated under stringent, clinically relevant, patient focused dose regimen modification (DRM) criteria starting from week 16 throughout the study. In the first year, patients in the aflibercept 8 mg groups could have their dosing intervals shortened down to an every 8-week interval if DRM criteria for disease progression were observed. Intervals could not be extended until the second year of the study. In the second year, patients in the aflibercept 8 mg groups could have their dosing intervals shortened or extended if DRM criteria were met. Patients in all Eylea® (aflibercept 2 mg) groups maintained a fixed 8-week dosing regimen throughout their participation in the trials. The two-year data mark the end of the masked study (week 96) with the option to extend treatment intervals up to 24 weeks and with an optional 1-year open-label extension for patients until week 156.
About nAMD and DME
Neovascular (wet) age-related macular degeneration (nAMD) is an eye disease that progresses rapidly and if left untreated can lead to vision loss in a few months. nAMD is one of the leading causes of irreversible blindness and vision impairment around the world. nAMD may affect people as they age. It occurs when abnormal blood vessels grow and leak fluid under the macula, the part of the eye responsible for sharp central vision and seeing fine detail. This fluid can damage and scar the macula, which can cause vision loss. 196 million people worldwide are living with AMD – it is anticipated that this figure will increase to 288 million by 2040. Approximately 10-15% of people with AMD will develop the advanced form nAMD.
Diabetic Macular Edema (DME) is a common complication in eyes of people living with diabetes. DME occurs when high levels of blood sugar lead to damaged blood vessels in the eye that leak fluid into the macula. This can lead to vision loss and, in some cases, blindness. Globally, 146 million people are currently living with diabetic retinopathy (DR), which can develop into a more serious condition which is DME. DME is affecting around 21 million people globally.
