Regeneron announced that the U.S. Food and Drug Administration approved its EYLEA HD (aflibercept) Injection 8 mg for the treatment of macular edema following retinal vein occlusion (RVO). The approval also adds a monthly dosing option for all four of the drug’s approved indications—wet age‑related macular degeneration, diabetic macular edema, diabetic retinopathy, and RVO—providing physicians with greater flexibility in patient management.
The decision was based on the Phase 3 QUASAR trial, which demonstrated that patients dosed every eight weeks after an initial monthly period achieved non‑inferior visual‑acuity gains compared with the standard four‑week dosing schedule of the 2 mg formulation. The trial’s results support the expanded dosing regimens and give the company a competitive advantage in a market that increasingly values fewer injections.
Regeneron’s Q3 2025 earnings report shows that U.S. net sales of EYLEA HD rose 10% to $431 million, while combined U.S. net sales of EYLEA HD and the legacy EYLEA formulation fell 28% to $1.11 billion. The shift toward the higher‑dose product reflects growing demand for the extended‑interval option, but the overall franchise decline highlights the need to sustain momentum in the legacy product line as the company transitions its portfolio.
Manufacturing challenges remain a potential headwind. A July 2025 FDA inspection of Catalent Indiana, LLC—Regeneron’s pre‑filled syringe filler—identified issues that could affect supply. Regeneron plans to submit an application for an alternate filler by January 2026, and the company has indicated that the transition is expected to be completed without significant disruption to the market launch.
The expanded dosing flexibility positions EYLEA HD against competitors such as Roche’s Vabysmo and Novartis’s Beovu. Analysts at Leerink Partners described the approval as a “pre‑holiday surprise” that improves EYLEA HD’s market footing, while BMO Capital Markets called the decision a “clear positive” that meaningfully improves the product’s profile. The monthly dosing option across all indications is expected to enhance patient adherence and physician convenience, key drivers of market share gains.
Management emphasized the strategic importance of the approval. Chief Medical Officer George D. Yancopoulos highlighted that EYLEA HD is the first RVO treatment that can potentially halve the number of injections patients receive compared with existing therapies, and that the new dosing options provide greater flexibility for physicians. He noted that the approval removes a regulatory hurdle that had delayed the drug’s launch by 18 months, thereby accelerating the company’s ability to capture market share in the growing retinal disease segment.
