Sanofi’s lunsekimig met primary and key secondary endpoints in phase 2 respiratory studies in asthma and CRSwNP
| • | The AIRCULES phase 2b study achieved its primary and key secondary endpoints in moderate-to-severe asthma regardless of biomarker status |
| • | The DUET phase 2a study met its primary and key secondary endpoints in chronic rhinosinusitis with nasal polyps, reinforcing lunsekimig’s potential as a respiratory treatment |
| • | The exploratory VELVET phase 2b study did not meet its primary endpoint in moderate-to-severe atopic dermatitis |
| • | In all studies, lunsekimig was well tolerated |
Paris, April 7, 2026. Phase 2 studies of lunsekimig in two chronic respiratory diseases met their primary and key secondary endpoints compared to placebo. Lunsekimig, a novel bispecific Nanobody® VHH, is made of five linked antibody fragments designed to simultaneously block TSLP and IL-13, two separate drivers of inflammation that contribute to tissue damage in asthma and related diseases. In both studies, lunsekimig was well tolerated, with an acceptable safety profile.
“These data are promising and support our belief that the dual-targeting mechanism of lunsekimig may offer a novel treatment option for patients living with respiratory diseases, including asthma,” said Houman Ashrafian, Executive Vice President, Head of Research & Development at Sanofi. “Importantly, these findings underscore lunsekimig’s potential to address multiple critical aspects of respiratory disease management through its unique mechanism.”
In the AIRCULES phase 2b study (clinical study identifier: NCT06102005), lunsekimig met its primary and key secondary endpoints demonstrating a statistically significant and clinically meaningful reduction in exacerbations and improvement in lung function, as measured by pre-bronchodilator forced expiratory volume in one second (pre-BD FEV1). The study enrolled adult patients with moderate-to-severe asthma, a form of the disease marked by recurrent symptoms and frequent flareups despite standard-of-care treatment.
The DUET phase 2a proof-of-concept study (clinical study identifier: NCT06454240), of lunsekimig in chronic rhinosinusitis with nasal polyps (CRSwNP), met its primary endpoint of change in nasal polyp score from baseline and met its key secondary endpoints of change in patient reported nasal congestion/obstruction score and change in Lund-Mackay Computed Tomography (LMK-CT) score, all compared to placebo at Week 24.
The separate exploratory VELVET phase 2b study (clinical study identifier: NCT06790121) evaluating lunsekimig in moderate-to-severe atopic dermatitis did not meet its primary endpoint of percent change from baseline in eczema area severity index (EASI) score. However, improvements were seen in the key secondary endpoints measuring skin clearance including EASI-75 (proportion of patients reaching a 75% or greater improvement in the EASI total score), and vIGA-AD 0/1 (proportion of patients reaching validated investigator global assessment scale for atopic dermatitis score of 0 or 1).
|
1/3 |
Across these studies, lunsekimig was generally well tolerated. In the AIRCULES study, among those who received at least one dose of lunsekimig, the most common (≥5%) treatment-emergent adverse events (TEAEs) were nasopharyngitis, upper respiratory tract infection, headache, and dose scheduling errors. In the DUET study, among those who received at least one dose of lunsekimig, the most common (≥5%) TEAEs were injection site reaction or erythema, viral upper respiratory tract infection, nasopharyngitis, epistaxis, ear pain, and increased creatine phosphokinase. Overall, rates of serious adverse events and TEAEs leading to treatment discontinuation in both studies were similar in the lunsekimig group and the placebo group. In the VELVET study, lunsekimig was generally well tolerated and had a safety profile consistent with the other studies.
Detailed results from the AIRCULES, DUET, and VELVET studies will be presented at upcoming medical congresses.
Lunsekimig is currently in clinical development in the AIRLYMPUS phase 2 study in high-risk asthma (clinical study identifier: NCT06676319) and in the PERSEPHONE and the THESEUS phase 3 studies (clinical study identifiers PERSEPHONE: NCT07190209, THESEUS: NCT07190222), and its safety and efficacy have not been evaluated by any regulatory authority.
About asthma
Asthma is one of the most common chronic diseases worldwide, with an estimated 262 million patients diagnosed globally as of 2019. However, despite several available therapies, more than 50% of patients have asthma that is not well controlled. A significant unmet need persists for treatments that prevent and reduce asthma exacerbations, which profoundly diminish patients’ quality of life, disrupt daily activities, and contribute substantially to healthcare resource utilization.
About CRSwNP
CRSwNP is a persistent inflammatory disease of the nose and sinuses characterized by the presence of soft, noncancerous growths, called nasal polyps, in the nasal passages. Individuals with CRSwNP often experience symptoms such as nasal congestion, facial pressure, and a reduced sense of smell, which can significantly impact their quality of life. The majority of patients with CRSwNP have comorbid asthma, which increases in frequency with severity of the disease.
About the AIRCULES study
AIRCULES was a randomized, double-blind, placebo-controlled, parallel-group, dose-ranging phase 2b study to evaluate the efficacy, safety, and tolerability of subcutaneous lunsekimig added to standard of care in adult patients with moderate-to-severe asthma across the range of FeNO (fractional exhaled nitric oxide) and eosinophil values. Lunsekimig was administered in multiple dosing regimens, and the primary endpoint was the annualized rate of asthma exacerbation events over 48 weeks. The key secondary endpoint evaluated lung function improvement, as measured by pre-BD FEV1 at Week 48. Lung function was assessed indirectly by measuring the volume of air a patient can exhale forcefully in one second. The study included sites across the US, Canada, Argentina, Brazil, Chile, China, India, Israel, Japan, Mexico, South Africa, South Korea, Turkey, and the UK.
About the DUET study
DUET was a randomized, double-blind, placebo-controlled, parallel-group phase 2a study designed to evaluate the efficacy, safety, and tolerability of subcutaneous lunsekimig in adult patients with chronic rhinosinusitis with nasal polyps (CRSwNP). Key objectives include measuring the efficacy and safety of lunsekimig compared to placebo over 24 weeks. The primary endpoint was change in nasal polyps score from baseline at Week 24 through bilateral endoscopy and the key secondary endpoints were change from baseline in patient-reported nasal congestion/obstruction score and change from baseline in LMK-CT score, both at Week 24. The study included sites across the US, Argentina, Belgium, Bulgaria, Poland, and the UK.
About the VELVET study
VELVET was a randomized, double-blind, placebo-controlled, multicenter exploratory study to assess the efficacy and safety of three subcutaneous dose regimens of lunsekimig in adult patients with moderate-to-severe atopic dermatitis. Key objectives include measuring the efficacy and safety of subcutaneous lunsekimig compared to placebo over 24 weeks. Lunsekimig was administered in three dosing regimens, and the primary endpoint was the percent change in EASI score from baseline at week 24. The study included sites across the United States, Czechia, Japan, and Poland.

About lunsekimig
Lunsekimig is a novel, pentavalent Nanobody® VHH that combines bispecific targeting of TSLP, an upstream initiator of inflammation and IL-13, a downstream cytokine causing tissue organ damage in respiratory diseases. As a pentavalent Nanobody® VHH (variable heavy-chain domains of a heavy-chain antibody), lunsekimig is made of five linked antibody fragments designed to simultaneously block TSLP and IL-13, which drive airway inflammation and can contribute to tissue damage in certain diseases and bind albumin for longer half-life. Pre-clinical research suggests that the combination of these targets simultaneously can potentially lead to additive and synergistic benefits in immune-mediated diseases such as asthma.

Sanofi and Regeneron’s Dupixent approved in the EU as the first targeted medicine to treat young children with chronic spontaneous urticaria
| • | Approval in CSU for children two to 11 years of age is based on data from the LIBERTY-CUPID clinical study program, including an extrapolation of efficacy data showing that Dupixent significantly reduced urticaria activity compared with placebo in adults |
| • | The latest approval expands Dupixent’s indication for CSU in the EU to children as young as two years; Dupixent is now approved for children less than 12 years of age across four chronic diseases driven in part by type 2 inflammation |
Paris and Tarrytown, NY, April 13, 2026. The European Commission has approved Dupixent (dupilumab) for the treatment of moderate-to-severe chronic spontaneous urticaria (CSU) in children aged two to 11 years with inadequate response to histamine-1 antihistamines (H1AH) and who are naïve to anti-immunoglobulin E (IgE) therapy for CSU. This expands the previous approval in the EU for adults and adolescents aged 12 years and older with CSU, a chronic, inflammatory skin disease that causes sudden and debilitating hives and recurring itch.
“Previous treatment options for young children with chronic spontaneous urticaria left many patients with uncontrolled disease where the unpredictable appearance of itch and hives continued to disrupt their daily lives,” said Alyssa Johnsen, MD, PhD, Global Therapeutic Area Head, Immunology Development at Sanofi. “Dupixent, which inhibits signaling of IL4 and IL13, two of the key and central drivers of type 2 inflammation, provides a first-of-its kind approach to addressing chronic spontaneous urticaria in young children. This approval demonstrates our commitment to extending the value of Dupixent to all who may benefit, including young children.”
The approval in the EU is based on data from the LIBERTY-CUPID clinical study program. This includes an extrapolation of efficacy data in adults from two phase 3 studies (Study A and Study C; clinical study identifier: NCT04180488) complemented by pharmacokinetic, safety, and efficacy data from the single-arm CUPIDKids phase 3 study in children aged two to 11 years with CSU (clinical study identifier: NCT05526521). Study A and Study C demonstrated Dupixent significantly reduced urticaria activity (a composite of itch and hives) and individual measures of itch and hive severity compared with placebo at Week 24. Dupixent also increased the percentage of patients with well-controlled disease and complete response at Week 24 compared with placebo.
Safety results from Study A, Study C, and CUPIDKids were generally consistent with the known safety profile of Dupixent in its approved dermatological indications. The most common adverse reactions for Dupixent overall are injection site reactions, conjunctivitis, conjunctivitis allergic, arthralgia, oral herpes, and eosinophilia. Additional adverse reactions of injection site induration, injection site dermatitis, and injection site bruising or hematoma were reported in the CSU adult and adolescent studies.* The adverse event more commonly observed with Dupixent (≥5%) than placebo in Study A and Study in adults and adolescents with CSU was COVID-19. Safety data for children aged two to 11 years with CSU were generally consistent with the safety profile for adult and adolescent patients with CSU treated with Dupixent.
“Young children suffering from chronic spontaneous urticaria often experience an unpredictable barrage of unrelenting itch and visible hives during the critical years of their growth and development. As the first and only targeted medicine for young children in the EU with CSU, Dupixent has the potential to become the new standard of care for those who remain symptomatic despite other available treatments,” said George D. Yancopoulos, MD, PhD, Board co-Chair, President and Chief Scientific Officer at Regeneron. “Dupixent is the most widely used innovative branded antibody medicine in the world, and this fourth approval for young children with chronic diseases driven in part by type 2 inflammation brings its proven efficacy and long-term safety profile to yet another vulnerable population in need.”
In the US, the supplemental biologics license application for Dupixent has been accepted for review in certain children aged two to 11 years with CSU. Dupixent is currently approved for CSU in certain adults and adolescents in many jurisdictions, including the US and Japan.
*Adverse reactions in adults and adolescents were pooled from Study A, Study B, and Study C. Study B evaluated Dupixent in patients aged 12 years and older who were inadequate responders or intolerant to anti-IgE therapy and symptomatic despite antihistamine use.
About CSU
CSU is a chronic, inflammatory skin disease driven in part by type 2 inflammation, which causes sudden and debilitating hives and recurring itch. CSU is typically treated with H1AH, medicines that target H1 receptors on cells to control symptoms of itch and urticaria. However, the disease remains uncontrolled despite H1AH treatment in many patients, some of whom are left with limited alternative treatment options. These individuals continue to experience symptoms that can be debilitating and significantly impact their quality of life.
About the Dupixent CSU phase 3 study program
The LIBERTY-CUPID phase 3 program evaluating Dupixent for CSU in children aged two to 11 years includes Study A, Study C, and CUPIDKids. CUPIDKids was a single arm clinical study that assessed the safety, efficacy, and pharmacokinetics of Dupixent in children aged two to 11 years with CSU who remained symptomatic despite the use of antihistamines. During the 24-week treatment period, Dupixent was administered at 200 mg every two (Q2W) or four weeks (Q4W) or 300 mg Q4W, with or without an initial loading dose, based on age and weight. The primary endpoint measured the serum concentration of Dupixent over time, including Ctrough (lowest concentration before the next dose) at Week 12 and Week 24.
Study A and Study C were replicate, double-blind, placebo-controlled clinical studies that assessed Dupixent as an add-on therapy to standard-of-care antihistamines compared to antihistamines alone in patients aged six years and older who remained symptomatic despite the use of antihistamines and were naïve to anti-IgE therapy. During the 24-week treatment period in both studies, all patients received an initial loading dose followed by either 300 mg Dupixent Q2W, or for pediatric patients weighing 30 kg to <60 kg, 200 mg Q2W. In both studies, endpoints assessed at Week 24 included:
| • | Change from baseline in itch and hives (weekly urticaria activity score [UAS7], 0-42 scale) the primary endpoint |
| • | Change from baseline in itch (measured by the weekly itch severity score, 0-21 scale), the key secondary endpoint |
| • | Change from baseline in hives (measured by the weekly hive severity score, 0-21 scale), secondary endpoint |
| • | Proportion of patients achieving well-controlled disease status (UAS7 ≤6) |
| • | Proportion of patients with complete response (UAS7=0) |
About Dupixent
Dupixent (dupilumab) is an injection administered under the skin (subcutaneous injection) at different injection sites. In children aged two to 11 years with CSU who remain symptomatic despite H1AH treatment, Dupixent is administered based on age and weight. In children aged two to five years, Dupixent is administered at 200 mg Q4W for patients weighing ≥5 kg to <15 kg and 300 mg Q4W for ≥15 kg to <30 kg, without an initial loading dose. In children and adolescents aged six to 17 years, Dupixent is administered at 300 mg Q4W for ≥15 kg to <30 kg,** 200 mg Q2W for ≥30 kg to <60kg, and 300mg Q2W for ≥60 kg, after an initial loading dose. Dupixent is intended for use under the guidance of a healthcare professional and can be given in a clinic or at home after training by a healthcare professional. In children aged two to 11 years, Dupixent should be administered by a caregiver if given at home.
Dupixent is a fully human monoclonal antibody that inhibits the signaling of the interleukin-4 (IL4) and interleukin-13 (IL13) 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 studies, establishing that IL4 and IL13 are two of the key and central drivers of the type 2 inflammation that plays a major role in multiple related and often co-morbid diseases.
Dupixent has received regulatory approvals in more than 60 countries in one or more indications including certain patients with atopic dermatitis, asthma, chronic rhinosinusitis with nasal polyps, eosinophilic esophagitis, prurigo nodularis, CSU, chronic obstructive pulmonary disease, bullous pemphigoid, and allergic fungal rhinosinusitis in different age populations. More than 1.4 million patients are being treated with Dupixent globally.
**For children and adolescents aged six to 17 years weighing 15 kg to <30 kg, the initial dose is 300 mg on Day 1 followed by 300 mg on Day 15. Subsequent doses are initiated four weeks after Day 15.
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 studies involving more than 12,000 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 studies, including chronic pruritus of unknown origin and lichen simplex chronicus. 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.
