Dupixent® (dupilumab) Demonstrated Superiority Over Xolair® (Omalizumab) in Chronic Rhinosinusitis with Nasal Polyps (CRSwNP) in Patients with Coexisting Asthma in First-ever Presented Phase 4 Head-to-Head Respiratory Trial
By GlobeNewswire Published on June 15, 2025, 20:21 IST New late-breaking data at EAACI showed Dupixent outperformed Xolair across all primary and secondary efficacy endpoints of CRSwNP and in all asthma-related endpoints Dupixent also outperformed Xolair in improving such key signs and symptoms as nasal polyp size and sense of smell in CRSwNP, and lung function and disease control in asthma, with rapid improvements seen as early as 4 weeks Results reinforce the efficacy of Dupixent in treating both upper and lower respiratory diseases by targeting IL-4 and IL-13, two key drivers of type 2 inflammation TARRYTOWN, N.Y. and PARIS, June 15, 2025 (GLOBE NEWSWIRE) — Regeneron Pharmaceuticals, Inc. (NASDAQ: REGN) and Sanofi today presented positive results from the EVEREST Phase 4 trial in adults with severe chronic rhinosinusitis with nasal polyps (CRSwNP) and coexisting asthma. In the trial, Dupixent® (dupilumab) outperformed Xolair® (omalizumab) on all primary and secondary efficacy endpoints of CRSwNP, and in all asthma-related endpoints. The data are from the first-ever presented head-to-head respiratory trial with biologic medicines and were shared in a late-breaking oral presentation at the 2025 European Academy of Allergy and Clinical Immunology (EAACI) Annual Congress. 'Patients suffering from chronic rhinosinusitis with nasal polyps often live with the constant obstruction of their nasal passages that can lead to burdensome nasal congestion and loss of smell. What's more, a majority of these individuals also have asthma that can substantially impact their quality of life,' said Eugenio De Corso, M.D., Ph.D., ENT Specialist, Otolaryngology, Head and Neck Surgery, Rhinology, A. Gemelli University Hospital Foundation, IRCSS, Rome, Italy, and lead investigator of the study. 'EVEREST is the first-ever trial to demonstrate the superiority of Dupixent over Xolair on CRSwNP endpoints in patients with coexisting asthma, along with generally similar safety profiles. Together, these Dupixent outcomes provide important insights that will help guide patients and physicians through the treatment decision-making process.' In the EVEREST trial, 360 adults with severe, uncontrolled CRSwNP and coexisting asthma were randomized to receive Dupixent 300 mg (n=181) every two weeks or a weight- and immunoglobulin E (IgE) level-based dosing regimen of Xolair (n=179) every two or four weeks. Both Dupixent and Xolair were added to background mometasone furoate nasal spray (MFNS). Primary and secondary endpoint results in CRSwNP for patients treated with Dupixent compared to Xolair at 24 weeks were as follows, with differences seen as early as 4 weeks: 1.60-point superior reduction in nasal polyp size , a primary endpoint (p<0.0001 a ) , a primary endpoint (p<0.0001 ) 8.0-point superior improvement in ability to identify different smells , a primary endpoint (p<0.0001 a ). More patients on Dupixent improved above the anosmia threshold compared to Xolair. , a primary endpoint (p<0.0001 ). More patients on Dupixent improved above the anosmia threshold compared to Xolair. 0.58-point superior reduction in nasal congestion/obstruction , a key secondary endpoint (p<0.0001 a ) , a key secondary endpoint (p<0.0001 ) 0.81-point superior improvement in loss of smell , a key secondary endpoint (p<0.0001 a ) , a key secondary endpoint (p<0.0001 ) 1.74-point superior reduction in symptom severity (p<0.0001 a ) (p<0.0001 ) 12.7-point difference in health-related quality of life (p<0.0001 b ) (p<0.0001 ) 31.27-point difference in peak nasal inspiratory flow (p<0.0001 b ) (p<0.0001 ) 1.87-point difference in overall severity of rhinosinusitis (p<0.0001b) Asthma endpoint results for patients treated with Dupixent compared to Xolair at 24 weeks were as follows, with differences seen as early as 4 weeks: 150 mL difference in lung function (pre-bronchodilator FEV 1 ; p=0.003 b ) (pre-bronchodilator FEV ; p=0.003 ) 0.48-point difference in asthma control (p<0.0001b) a Statistically significant b Nominally significant as the endpoint was not included in the multiplicity adjustment hierarchy The safety results in the EVEREST trial were generally consistent with the known safety profile of Dupixent in its approved respiratory indications, with similar overall rates of adverse events (AEs) observed between Dupixent (64%) and Xolair (67%). Serious AEs were reported in 2% and 4% of patients treated with Dupixent and Xolair, respectively. Additionally, AEs leading to trial discontinuation were reported in 3% of Dupixent patients and 1% of Xolair patients. About the Dupixent Phase 4 Trial EVEREST is a randomized, double-blind Phase 4 trial comparing the efficacy and safety of Dupixent to Xolair in adults with severe, uncontrolled CRSwNP and coexisting mild, moderate or severe asthma. During the 24-week trial, patients received Dupixent 300 mg every two weeks or Xolair 75 to 600 mg every two or four weeks, which was added to background MFNS. Xolair dosing was determined based on body weight and serum total IgE levels as per the approved label. All endpoints were assessed at 24 weeks. The primary endpoints assessed change from baseline in nasal polyp score (NPS; scale: 0-8) and the University of Pennsylvania Smell Identification Test (UPSIT; scale: 0-40). Secondary endpoints included change from baseline in nasal congestion (NC; scale: 0-3), loss of smell (LoS; scale: 0-3), total symptom score (TSS; scale: 0-9), Sino-Nasal Outcome Test-22 (SNOT-22; scale: 0-110), peak nasal inspiratory flow, and rhinosinusitis disease severity (visual analogue scale: 0-10 cm). Other endpoints assessed pre-bronchodilator forced expiratory volume over one second (pre-BD FEV 1 ) and the 7-item Asthma Control Questionnaire (ACQ-7; scale: 0-6). About Dupixent Dupixent, which was invented using Regeneron's proprietary VelocImmune ® technology, 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 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, CRSwNP, eosinophilic esophagitis (EoE), prurigo nodularis, chronic spontaneous urticaria (CSU) and chronic obstructive pulmonary disease (COPD) in different age populations. More than 1,000,000 patients are being treated with Dupixent globally.1 About Regeneron's VelocImmune Technology Regeneron's VelocImmune technology utilizes a proprietary genetically engineered mouse platform endowed with a genetically humanized immune system to produce optimized fully human antibodies. When Regeneron's co-Founder, President and Chief Scientific Officer George D. Yancopoulos was a graduate student with his mentor Frederick W. Alt in 1985, they were the first to envision making such a genetically humanized mouse, and Regeneron has spent decades inventing and developing VelocImmune and related VelociSuite ® technologies. Dr. Yancopoulos and his team have used VelocImmune technology to create a substantial proportion of all original, FDA-approved fully human monoclonal antibodies. This includes Dupixent® (dupilumab), Libtayo® (cemiplimab-rwlc), Praluent® (alirocumab), Kevzara® (sarilumab), Evkeeza® (evinacumab-dgnb), Inmazeb® (atoltivimab, maftivimab and odesivimab-ebgn) and Veopoz® (pozelimab-bbfg). In addition, REGEN-COV® (casirivimab and imdevimab) had been authorized by the FDA during the COVID-19 pandemic until 2024. Dupilumab Development Program Dupilumab is being jointly developed by Regeneron and Sanofi 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, Regeneron and Sanofi 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, bullous pemphigoid 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.

Press Release: EAACI: Dupixent demonstrated superiority over Xolair (omalizumab) in chronic rhinosinusitis with nasal polyps in patients with coexisting asthma in first-ever presented phase 4 head-to-head respiratory study
EAACI: Dupixent demonstrated superiority over Xolair (omalizumab) in chronic rhinosinusitis with nasal polyps in patients with coexisting asthma in first-ever presented phase 4 head-to-head respiratory study New late-breaking data at EAACI showed Dupixent outperformed Xolair across all primary and secondary efficacy endpoints of CRSwNP and in all asthma-related endpoints Dupixent also outperformed Xolair in improving such key signs and symptoms as nasal polyp size and sense of smell in CRSwNP, and lung function and disease control in asthma, with rapid improvements seen as early as 4 weeks Results reinforce the efficacy of Dupixent in treating both upper and lower respiratory diseases by targeting IL-4 and IL-13, two key drivers of type 2 inflammation Paris and Tarrytown, NY, June 15, 2025. Sanofi and Regeneron Pharmaceuticals, Inc. today presented positive results from the EVEREST phase 4 study of adults with severe chronic rhinosinusitis with nasal polyps (CRSwNP) and coexisting asthma. In the study, Dupixent (dupilumab) outperformed Xolair (omalizumab) on all primary and secondary efficacy endpoints of CRSwNP, and in all asthma-related endpoints. The data are from the first-ever presented head-to-head respiratory study with biologic medicines and were shared today in a late-breaking oral presentation at the 2025 European Academy of Allergy and Clinical Immunology (EAACI) Annual Congress, Glasgow, UK. ENT Specialist, Otolaryngology, Head and Neck Surgery, Rhinology, A. Gemelli University Hospital Foundation, IRCSS, Rome, Italy, and lead investigator of the study 'Patients suffering from chronic rhinosinusitis with nasal polyps often live with the constant obstruction of their nasal passages that can lead to burdensome nasal congestion and loss of smell. What's more, a majority of these individuals also have asthma that can substantially impact their quality of life. EVEREST is the first-ever trial to demonstrate the superiority of Dupixent over Xolair on CRSwNP endpoints in patients with coexisting asthma, along with generally similar safety profiles. Together, these Dupixent outcomes provide important insights that will help guide patients and physicians through the treatment decision-making process.' In the EVEREST study, 360 adults with severe, uncontrolled CRSwNP and coexisting asthma were randomized to receive Dupixent 300 mg (n=181) every two weeks or a weight- and immunoglobulin E (IgE) level-based dosing regimen of omalizumab (n=179) every two or four weeks. Both Dupixent and omalizumab were added to background mometasone furoate nasal spray (MFNS). Primary and secondary endpoint results in CRSwNP for patients treated with Dupixent compared to omalizumab at 24 weeks were as follows with differences were seen as early as four weeks: 1.60-point superior reduction in nasal polyp size, a primary endpoint (p<0.00011) 8.0-point superior improvement in ability to identify different smells, a primary endpoint (p<0.00011). More patients on Dupixent improved above the anosmia threshold compared to omalizumab 0.58-point superior reduction in nasal congestion/obstruction, a key secondary endpoint (p<0.00011) 0.81-point superior improvement in loss of smell, a key secondary endpoint (p<0.00011) 1.74-point superior reduction in symptom severity (p<0.00011) 12.7-point difference in health-related quality of life (p<0.00012) 31.27-point difference in peak nasal inspiratory flow (p<0.00012) 1.87 difference in overall severity of rhinosinusitis (p<0.00012) Asthma endpoint results for patients treated with Dupixent compared to omalizumab at 24 weeks were as follows, with differences seen as early as four weeks: 150 mL difference in lung function (pre-bronchodilator FEV1; p=0.0032) 0.48-point difference in asthma control (p<0.00012) The safety results in the EVEREST study were generally consistent with the known safety profile of Dupixent in its approved respiratory indications, with similar overall rates of adverse events (AEs) observed between Dupixent (64%) and omalizumab (67%). Serious AEs were reported in 2% and 4% of patients treated with Dupixent and omalizumab, respectively. Additionally, AEs leading to study discontinuation were reported in 3% of Dupixent patients and 1% of omalizumab patients. About the Dupixent phase 4 studyEVEREST is a randomized, double-blind phase 4 study comparing the efficacy and safety of Dupixent to omalizumab in adults with severe, uncontrolled CRSwNP and coexisting mild, moderate, or severe asthma. During the 24-week study, patients received Dupixent 300 mg every two weeks or omalizumab 75 to 600 mg every two or four weeks, which was added to background MFNS. Omalizumab dosing was determined based on body weight and serum total IgE levels as per the approved label. All endpoints were assessed at 24 weeks. The primary endpoints assessed change from baseline in nasal polyp score (scale: 0-8) and the University of Pennsylvania Smell Identification Test (scale: 0-40). Secondary endpoints included change from baseline in nasal congestion (scale: 0-3), loss of smell (scale: 0-3), total symptom score (scale: 0-9), SNOT-22 (scale: 0-110), peak nasal inspiratory flow, and rhinosinusitis disease severity (visual analogue scale: 0-10 cm). Other endpoints assessed pre-bronchodilator forced expiratory volume over one second and the 7-item Asthma Control Questionnaire (scale: 0-6). About DupixentDupixent (dupilumab) 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, CRSwNP, eosinophilic esophagitis, prurigo nodularis, chronic spontaneous urticaria, and chronic obstructive pulmonary disease in different age populations. More than one million patients are being treated with Dupixent globally. Dupilumab development programDupilumab 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 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 studies, including chronic pruritus of unknown origin, bullous pemphigoid, 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.

Dupixent® (dupilumab) Demonstrated Superiority Over Xolair® (Omalizumab) in Chronic Rhinosinusitis with Nasal Polyps (CRSwNP) in Patients with Coexisting Asthma in First-ever Presented Phase 4 Head-to-Head Respiratory Trial
New late-breaking data at EAACI showed Dupixent outperformed Xolair across all primary and secondary efficacy endpoints of CRSwNP and in all asthma-related endpoints Dupixent also outperformed Xolair in improving such key signs and symptoms as nasal polyp size and sense of smell in CRSwNP, and lung function and disease control in asthma, with rapid improvements seen as early as 4 weeks Results reinforce the efficacy of Dupixent in treating both upper and lower respiratory diseases by targeting IL-4 and IL-13, two key drivers of type 2 inflammation TARRYTOWN, N.Y. and PARIS, June 15, 2025 (GLOBE NEWSWIRE) -- Regeneron Pharmaceuticals, Inc. (NASDAQ: REGN) and Sanofi today presented positive results from the EVEREST Phase 4 trial in adults with severe chronic rhinosinusitis with nasal polyps (CRSwNP) and coexisting asthma. In the trial, Dupixent® (dupilumab) outperformed Xolair® (omalizumab) on all primary and secondary efficacy endpoints of CRSwNP, and in all asthma-related endpoints. The data are from the first-ever presented head-to-head respiratory trial with biologic medicines and were shared in a late-breaking oral presentation at the 2025 European Academy of Allergy and Clinical Immunology (EAACI) Annual Congress. 'Patients suffering from chronic rhinosinusitis with nasal polyps often live with the constant obstruction of their nasal passages that can lead to burdensome nasal congestion and loss of smell. What's more, a majority of these individuals also have asthma that can substantially impact their quality of life,' said Eugenio De Corso, M.D., Ph.D., ENT Specialist, Otolaryngology, Head and Neck Surgery, Rhinology, A. Gemelli University Hospital Foundation, IRCSS, Rome, Italy, and lead investigator of the study. 'EVEREST is the first-ever trial to demonstrate the superiority of Dupixent over Xolair on CRSwNP endpoints in patients with coexisting asthma, along with generally similar safety profiles. Together, these Dupixent outcomes provide important insights that will help guide patients and physicians through the treatment decision-making process.' In the EVEREST trial, 360 adults with severe, uncontrolled CRSwNP and coexisting asthma were randomized to receive Dupixent 300 mg (n=181) every two weeks or a weight- and immunoglobulin E (IgE) level-based dosing regimen of Xolair (n=179) every two or four weeks. Both Dupixent and Xolair were added to background mometasone furoate nasal spray (MFNS). Primary and secondary endpoint results in CRSwNP for patients treated with Dupixent compared to Xolair at 24 weeks were as follows, with differences seen as early as 4 weeks: 1.60-point superior reduction in nasal polyp size, a primary endpoint (p<0.0001a) 8.0-point superior improvement in ability to identify different smells, a primary endpoint (p<0.0001a). More patients on Dupixent improved above the anosmia threshold compared to Xolair. 0.58-point superior reduction in nasal congestion/obstruction, a key secondary endpoint (p<0.0001a) 0.81-point superior improvement in loss of smell, a key secondary endpoint (p<0.0001a) 1.74-point superior reduction in symptom severity (p<0.0001a) 12.7-point difference in health-related quality of life (p<0.0001b) 31.27-point difference in peak nasal inspiratory flow (p<0.0001b) 1.87-point difference in overall severity of rhinosinusitis (p<0.0001b) Asthma endpoint results for patients treated with Dupixent compared to Xolair at 24 weeks were as follows, with differences seen as early as 4 weeks: 150 mL difference in lung function (pre-bronchodilator FEV1; p=0.003b) 0.48-point difference in asthma control (p<0.0001b) aStatistically significantbNominally significant as the endpoint was not included in the multiplicity adjustment hierarchy The safety results in the EVEREST trial were generally consistent with the known safety profile of Dupixent in its approved respiratory indications, with similar overall rates of adverse events (AEs) observed between Dupixent (64%) and Xolair (67%). Serious AEs were reported in 2% and 4% of patients treated with Dupixent and Xolair, respectively. Additionally, AEs leading to trial discontinuation were reported in 3% of Dupixent patients and 1% of Xolair patients. About the Dupixent Phase 4 TrialEVEREST is a randomized, double-blind Phase 4 trial comparing the efficacy and safety of Dupixent to Xolair in adults with severe, uncontrolled CRSwNP and coexisting mild, moderate or severe asthma. During the 24-week trial, patients received Dupixent 300 mg every two weeks or Xolair 75 to 600 mg every two or four weeks, which was added to background MFNS. Xolair dosing was determined based on body weight and serum total IgE levels as per the approved label. All endpoints were assessed at 24 weeks. The primary endpoints assessed change from baseline in nasal polyp score (NPS; scale: 0-8) and the University of Pennsylvania Smell Identification Test (UPSIT; scale: 0-40). Secondary endpoints included change from baseline in nasal congestion (NC; scale: 0-3), loss of smell (LoS; scale: 0-3), total symptom score (TSS; scale: 0-9), Sino-Nasal Outcome Test-22 (SNOT-22; scale: 0-110), peak nasal inspiratory flow, and rhinosinusitis disease severity (visual analogue scale: 0-10 cm). Other endpoints assessed pre-bronchodilator forced expiratory volume over one second (pre-BD FEV1) and the 7-item Asthma Control Questionnaire (ACQ-7; scale: 0-6). About DupixentDupixent, which was invented using Regeneron's proprietary VelocImmune® technology, 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 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, CRSwNP, eosinophilic esophagitis (EoE), prurigo nodularis, chronic spontaneous urticaria (CSU) and chronic obstructive pulmonary disease (COPD) in different age populations. More than 1,000,000 patients are being treated with Dupixent globally.1 About Regeneron's Technology Regeneron's VelocImmune technology utilizes a proprietary genetically engineered mouse platform endowed with a genetically humanized immune system to produce optimized fully human antibodies. When Regeneron's co-Founder, President and Chief Scientific Officer George D. Yancopoulos was a graduate student with his mentor Frederick W. Alt in 1985, they were the first to envision making such a genetically humanized mouse, and Regeneron has spent decades inventing and developing VelocImmune and related VelociSuite® technologies. Dr. Yancopoulos and his team have used VelocImmune technology to create a substantial proportion of all original, FDA-approved fully human monoclonal antibodies. This includes Dupixent® (dupilumab), Libtayo® (cemiplimab-rwlc), Praluent® (alirocumab), Kevzara® (sarilumab), Evkeeza® (evinacumab-dgnb), Inmazeb® (atoltivimab, maftivimab and odesivimab-ebgn) and Veopoz® (pozelimab-bbfg). In addition, REGEN-COV® (casirivimab and imdevimab) had been authorized by the FDA during the COVID-19 pandemic until 2024. Dupilumab Development Program Dupilumab is being jointly developed by Regeneron and Sanofi 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.

New real-world study reveals oral corticosteroid overuse in patients with chronic rhinosinusitis with nasal polyps Français
According to the ACTIONS study, 39% of patients with chronic rhinosinusitis with nasal polyps (CRSwNP) faced overexposure to oral corticosteroids (OCS) before beginning biologic therapy. ACTIONS was carried out by GSK in collaboration with Asthma Canada and leading Canadian Rhinologists. MISSISSAUGA, ON, June 10, 2025 /CNW/ - A new Canadian real-world study, ACTIONS (chAracterizing oral Corticosteroid use in patients with chronic rhInOsinusitis with Nasal polypS in Canada), revealed patterns of oral corticosteroid (OCS) use among patients with chronic rhinosinusitis with nasal polyps (CRSwNP) prior to starting biologic treatments. The full findings were recently presented at the Canadian Society of Otolaryngology Head and Neck Surgery Annual Meeting in Fredericton, New Brunswick. The study findings revealed that 81% of CRSwNP patients were prescribed OCS at least once in the 24 months prior to starting a biologic treatment with 39% of patients being overexposed to OCS by the time they started a biologic. These findings highlight the need for heightened awareness and education to prevent OCS overexposure and enhance patient care. CRSwNP is a chronic inflammatory disease of the paranasal sinuses and nasal mucosa leading to the growth of nasal polyps; 1 CRSwNP is associated with significant disease burden which negatively affects patients' quality of life. 2 Treatment for CRSwNP involves a combination of medical and surgical interventions. OCS are a common and effective medical treatment option for patients with CRSwNP, often used alongside nasal saline irrigation for short-term control of symptoms. 3 Despite their proven short-term efficacy, OCS are also associated with increased risk of short- and long-term adverse effects, with guidelines in respiratory disease recommending limiting use when possible. 4,5 Biologics have emerged as a newer treatment option with demonstrated effectiveness in managing CRSwNP, including decreasing the dependence on OCS. 6-8 The ACTIONS study revealed critical patterns of OCS use among CRSwNP patients, underscoring a significant unmet need that healthcare professionals should address. ACTIONS was conducted by GSK and Asthma Canada in collaboration with Dr. Yvonne Chan from the University of Toronto, Dr. Marie-Noëlle Corriveau from Université Laval, and Dr. Andrew Thamboo from the University of British Columbia, with research support, input, and analytics provided by IQVIA Solutions Canada Inc. "Our findings indicate that a significant proportion of severe CRSwNP patients are at risk of OCS overexposure. By considering earlier biologic initiation, when indicated, we can potentially reduce this risk and improve patient outcomes. Furthermore, collaboration among healthcare providers to promote awareness and adherence to these protocols will be vital in transforming patient care," said Dr. Marie-Noëlle Corriveau. "The data clearly indicate that a proactive strategy involving earlier biologic therapy can play a pivotal role in managing CRSwNP more efficiently. Embracing these new approaches is not just beneficial, but essential for improving the quality of life for our patients," said Dr. Yvonne Chan. "CRSwNP and asthma often coexist, share underlying mechanisms and influence each other's severity and management. This study is a critical step forward in understanding the treatment landscape for CRSwNP. It shows how vital it is to reduce our dependence on OCS and to find more sustainable and effective treatments. Ultimately, this could mean better health and quality of life for patients," said Jeffrey Beach, President & CEO, Asthma Canada. "As a leader in respiratory health, GSK remains committed to be at the forefront of the fight against respiratory disease. The ACTIONS study further underscores this dedication by providing valuable insights, fostering scientific and research excellence, and driving innovation," added Dr. Michelle Horn, Country Medical Director, GSK Canada. About CRSwNP CRSwNP is caused by inflammation of the nasal lining that can lead to soft tissue growths, known as nasal polyps. 3,6 People with CRSwNP experience symptoms such as nasal obstruction, loss of smell, facial pain, sleep disturbance, infections and nasal discharge that can significantly affect their emotional and physical well-being. 1,6,10-11 IL-5 is a key cytokine (protein) in type 2 inflammation characterized by eosinophils (a type of white blood cell), which is present in up to 85% of people with CRSwNP. 1,6,10,11 IL-5 and eosinophils are frequently found in high concentrations in sinus and nasal polyp tissue of patients with CRSwNP and are associated with more severe disease. 13-19 About OCS Oral corticosteroids (OCS) are systemic anti-inflammatory medications used to manage inflammatory conditions, including respiratory diseases, and allergic reactions. Unlike inhaled corticosteroids (ICS), which target the lungs directly, and intranasal corticosteroids (INCS) which target the nasal airways, OCS are ingested and distributed throughout the body. Common types include prednisone, methylprednisolone, and hydrocortisone. The use of OCS, including in repeated short bursts, can lead to significant health risks. The wide range of adverse effects associated with OCS include increased risk of infection and cardiovascular events, osteoporosis, type 2 diabetes mellitus, weight gain, and mood and behaviour disturbances. 20 In the ACTIONS study, overexposure to OCS is defined as total yearly dose of OCS ≥1,000 mg given that the risk of adverse effects significantly increases once a patient receives a cumulative lifetime exposure of 1000mg of OCS. 20 About GSK in respiratory GSK continues to build on decades of pioneering work to deliver more ambitious treatment goals, develop the next generation standard of care, and redefine the future of respiratory medicine for hundreds of millions of people with respiratory diseases. With an industry-leading respiratory portfolio and pipeline of vaccines, targeted biologics and inhaled medicines, we are focused on improving outcomes and the lives of people living with all types of asthma and COPD along with less understood refractory chronic cough or rarer conditions like systemic sclerosis with interstitial lung disease.
