Sanofi SNY and partner Regeneron REGN announced that the FDA has approved its blockbuster medicine Dupixent (dupilumab) for a new indication — eosinophilic esophagitis (EoE).
The FDA has approved the use of Dupixent for treating adults and children aged 12 and older with EoE, a chronic, progressive inflammatory disease. The FDA’s decision came much earlier than the PDUFA date of Aug 3, 2022. Dupixent is the first and only medicine indicated for eosinophilic esophagitis in the United States.
EoE inflates and damages the esophagus, which makes it difficult for the patients to eat and swallow, leading to poor quality of life. There are no approved treatments specifically for this disease, thus creating huge unmet demand. Dupixent, in studies, has demonstrated that it improves the ability to swallow and also reduce the inflammation in the esophagus.
EoE is the fourth disease for which Dupixent is now indicated and also represents the first indication for a gastrointestinal disease. Sanofi and Regeneron’s Dupixent is already approved in the United States, EU and some other countries for three type II inflammatory diseases, namely for certain patients with chronic rhinosinusitis with nasal polyposis, asthma and atopic dermatitis in different age populations. Dupixent is under review in Europe for EoE.
Sanofi stock has risen 8.6% this year so far compared with the industry’s increase of 4.4%.

Dupixent is being jointly marketed by Regeneron and Sanofi under a global collaboration agreement. Sanofi records global net product sales of Dupixent while Regeneron records its share of profits/losses in connection with the global sales of the drug.
Dupixent sales are now annualizing at close to €6.0 billion after around three years on the market. Sanofi expects Dupixent to achieve more than €13 billion in peak sales. The drug’s frequent label expansion approvals are driving sales higher. With outside U.S. revenues accelerating and multiple approvals for new indications and expansion in younger patient populations expected in the near future, its sales are expected to be higher
Dupixent has become the key driver of the top line for Sanofi. Dupixent generated first-quarter global product sales of $1.61 billion, which were recorded by Sanofi.
Sanofi and Regeneron are also studying dupilumab in late-stage studies in a broad range of diseases, driven by type II inflammation like bullous pemphigoid, chronic spontaneous urticaria, prurigo nodularis, and chronic obstructive pulmonary disease.
