Presentations underscore the importance of understanding how patients experience skin diseases and measuring outcomes in clinical and real-world studies that are meaningful to patients.

Clinical and long-term data in AD

• LIBERTY AD-OLE trial: Findings across three abstracts from this open-label extension study will be presented including long-term data on Dupixent in AD for up to 5 years.
   
• LIBERTY AD-HAFT: Positive Dupixent data will be presented during an oral presentation in patients with AD with moderate-to-severe hand and foot involvement. 
   
• LIBERTY AD-PED-OLE trial: Positive Dupixent findings will be presented from an open-label extension pediatric study in patients aged 6 months to 17 years with AD.
   
• PEDISTAD international study: Findings to be presented from this 10-year, ongoing observational study evaluating moderate-to-severe AD and its impact on growth in children aged <12 years. This abstract was awarded first place in the Annual Meeting Poster Awards.
   
• PELISTAD pediatric open-label trial: Positive data from two oral presentations will be presented evaluating Dupixent and skin barrier function in children aged 6 to 11 years with moderate-to-severe AD.

Clinical data in PN

• LIBERTY-PN PRIME and PRIME2 pivotal trials: Dupixent was associated with positive data in a pooled subgroup analysis in patients with PN regardless of patient body mass index (BMI).

The safety results of these trials were generally consistent with the known safety profile of Dupixent in its approved dermatological indications.

Amlitelimab
Three presentations show results for novel anti-OX40-Ligand monoclonal antibody amlitelimab for the treatment of AD. 

• STREAM-AD: Up to 52-week Phase 2b efficacy and safety results for amlitelimab in patients with moderate-to-severe atopic dermatitis (AD).

About Dupixent 
Dupixent is a fully human monoclonal antibody that inhibits the signaling of the interleukin-4 (IL-4) and interleukin-13 (IL-13) pathways and is not an immunosuppressant. The Dupixent development program has shown significant clinical benefit and a decrease in type 2 inflammation in Phase 3 trials, establishing that IL-4 and IL-13 are key and central drivers of the type 2 inflammation that plays a major role in multiple related and often co-morbid diseases. These diseases include approved indications for Dupixent, such as atopic dermatitis, asthma, chronic rhinosinusitis with nasal polyposis (CRSwNP), prurigo nodularis and EoE, and chronic spontaneous urticaria (CSU) (in Japan).  

Dupixent has received regulatory approvals in one or more countries around the world for use in certain patients with atopic dermatitis, asthma, CRSwNP, EoE, and prurigo nodularis in different age populations. Dupixent is currently approved for one or more of these indications in more than 60 countries, including in Europe, the U.S. and Japan. More than 800,000 patients are being treated with Dupixent globally. 

Dupilumab Development Program 
Dupilumab is being jointly developed by Sanofi and Regeneron under a global collaboration agreement. To date, dupilumab has been studied across more than 60 clinical trials involving more than 10,000 patients with various chronic diseases driven in part by type 2 inflammation.  

In addition to the currently approved indications, Sanofi and Regeneron are studying dupilumab in a broad range of diseases driven by type 2 inflammation or other allergic processes in Phase 3 trials, including chronic pruritus of unknown origin, chronic obstructive pulmonary disease (COPD) with evidence of type 2 inflammation, and bullous pemphigoid. These potential uses of dupilumab are currently under clinical investigation, and the safety and efficacy in these conditions have not been fully evaluated by any regulatory authority. 

About Amlitelimab
Amlitelimab is a fully human, non-T cell  non-depleting monoclonal antibody that binds to OX40-Ligand, a key immune regulator, and has the potential to be a first-in-class treatment for a range of immune-mediated diseases and inflammatory disorders, including moderate-to-severe atopic dermatitis (Phase 3), asthma (Phase 2), hidradenitis suppurativa (Phase 2), scleroderma, celiac disease, and alopecia (Phase 2 studies to be initiated in 2024). By targeting OX40-Ligand, amlitelimab aims to restore balance between pro-inflammatory and regulatory T cells.

Amlitelimab is currently under clinical investigation, and its safety and efficacy have not been evaluated by any regulatory authority.

U.S. INDICATIONS 

DUPIXENT is a prescription medicine used:

• to treat adults and children 6 months of age and older with moderate-to-severe eczema (atopic dermatitis or AD) that is not well controlled with prescription therapies used on the skin (topical), or who cannot use topical therapies.
