Strong Commercial Performance: Regeneron reported a solid second quarter with total revenues of $3.7 billion, a 4% increase year-over-year (YOY). Global net product sales for Dupixent grew 21% at constant currency, reaching $4.3 billion, reflecting significant demand across various indications and demographics. Libtayo also saw a 25% increase YOY in net sales, indicating strong market performance.

EYLEA HD Performance & Challenges: EYLEA HD U.S. net product sales hit a record $393 million, driven by a sequential demand increase, marking a positive trend. However, EYLEA sales faced a 39% YOY decline due to competitive pressures and a shift toward EYLEA HD. Challenges include payer reimbursements and potential delays in approval for new product enhancements stemming from regulatory issues at the Catalent site.

Catalent Site Inspection Impact: The Catalent site inspection delay has impacted the approval timelines of EYLEA HD enhancements and odronextamab, leading to a Complete Response Letter (CRL) from the FDA. While no major structural changes are required, this procedural issue could delay critical product launches and is an area of concern.
