Live News

On Wednesday, April 22, 2026, Regeneron and Sanofi confirmed the FDA authorization expands Dupixent’s prior CSU approval, which was previously limited to patients 12 years and older. The approval is rooted in data from the LIBERTY-CUPID Phase 3 clinical program, which extrapolated efficacy and safety results from two placebo-controlled trials in adults and adolescents with CSU, paired with pharmacokinetic and safety data from the single-arm CUPIDKids trial in the 2-11 age group.

Expert Insights

We view this approval as a material low-risk, high-upside catalyst for Regeneron, which derived 58% of its 2025 total annual revenue of $16.2 billion from Dupixent, per its latest 10-K filing. Unlike early-stage pipeline readouts that carry high failure risk, this indication expansion leverages Dupixent’s established commercial infrastructure and payer relationships, requiring minimal incremental sales and marketing investment to capture the new pediatric CSU patient population. We upgrade our 2027 Dupixent revenue forecast by 2.1% to $19.2 billion, from a prior $18.8 billion, to reflect the new indication, with upside risk if payer coverage for the pediatric cohort exceeds consensus assumptions. Critically, this approval de-risks Regeneron’s broader pediatric Dupixent pipeline, as the FDA’s acceptance of extrapolated adult efficacy data to pediatric populations lowers development costs and timelines for upcoming submissions, including the ongoing Phase 3 trial for chronic pruritus of unknown origin in patients as young as 6 months old. From a valuation perspective, REGN trades at 18.2x 2026 consensus earnings per share (EPS), a 12% discount to its large-cap biotech peer group average of 20.7x, a gap driven by investor concerns over Dupixent’s core patent expirations starting in 2031. However, the steady cadence of indication expansions, including this pediatric CSU approval, extends Dupixent’s revenue growth trajectory and lifts consensus peak sales estimates to $24 billion by 2029, up from a prior $22 billion, partially offsetting long-term patent expiry risks. We maintain our Outperform rating on REGN with a 12-month price target of $1,320, implying 17% upside from its April 22, 2026 closing price of $1,128. Key downside risks include slower than expected payer adoption for the new indication, increased regulatory scrutiny of Dupixent’s long-term safety profile, and earlier than expected biosimilar entry.
