NACI also recommends that adults aged 60-74 years may consider RSV vaccination in consultation with a health care provider.<sup>3</sup></p>\n<p>A systematic review of studies in the US showed that RSV is estimated to cause 42,000 hospitalizations* each year in adults aged 50-64 years old.<sup>4 </sup>Further, among Canadian adults aged 50 and older hospitalized with RSV, about 98 per cent have at least one chronic condition.<sup>5</sup> Adults with chronic medical conditions, such as chronic obstructive pulmonary disease (COPD), asthma, heart failure and diabetes, are at increased risk for severe consequences from an RSV infection compared to those without these conditions.<sup>6,7</sup> RSV can exacerbate these conditions and lead to pneumonia, hospitalization, or death.<sup>8 </sup></p>\n<p><strong>Michelle Horn, Interim Country Medical Director, GSK</strong>, said: “The natural age-related decline in immune function we all experience, which can increase our vulnerability to viruses like RSV, becomes more evident the older we get. Not surprisingly, incidence of RSV-associated hospitalizations in adults starts to increase at the age of 50. For adults with underlying medical conditions, RSV can worsen these conditions and lead to serious consequences. We are proud to be the first to provide a vaccine to help protect Canadians aged 50-59 at increased risk of lower respiratory tract disease caused by RSV.”</p>\n<p>The expanded age indication is based on the <a rel=\"noopener\" href=\"https://pubmed.ncbi.nlm.nih.gov/39099093/#:~:text=Background: The adjuvanted respiratory syncytial virus (RSV)\" target=\"_blank\" data-anchor=\"#:~:text=Background: The adjuvanted respiratory syncytial virus (RSV)\" title=\"Opens in a new window\">positive results</a> from a phase III trial [NCT05590403] evaluating the immune response and safety of GSK’s RSV vaccine in adults aged 50-59, including those at increased risk for RSV-LRTD due to underlying medical conditions.</p>\n<p>Approval of an expanded age indication for AREXVY in Canada follows similar approvals in the US and the EU. GSK has also filed regulatory submissions to extend the use of its RSV vaccine to adults aged 50-59 at increased risk in Japan and other geographies with regulatory decisions undergoing review. Trials evaluating the immunogenicity and safety of the vaccine in adults aged 18-49 at increased risk and immunocompromised adults aged 18 and over are expected to read out later in 2024. The safety and effectiveness of Arexvy in adults aged 18-49 at increased risk for RSV disease and immunocompromised adults aged 18 and over are still under investigation and authorization has not yet been granted in any country.</p>\n<p><strong>About Arexvy </strong></p>\n<p><em>Arexvy</em> is currently approved in Canada for the prevention of lower respiratory tract disease (LRTD) caused by respiratory syncytial virus (RSV) in adults 60 years of age and older, and in adults 50 through 59 years of age who are at increased risk for RSV disease.</p>\n<p>Respiratory syncytial virus vaccine, adjuvanted, contains recombinant glycoprotein F stabilised in the prefusion conformation (RSVPreF3). This antigen is combined with GSK’s proprietary AS01<sub>E</sub> adjuvant.</p>\n<p>The GSK proprietary AS01 adjuvant system contains STIMULON QS-21 adjuvant licensed from Antigenics Inc, a wholly owned subsidiary of Agenus Inc. STIMULON is a trademark of SaponiQx Inc., a subsidiary of Agenus.</p>\n<p><strong>About the NCT05590403 trial</strong></p>\n<p>NCT05590403 is a phase III, placebo-controlled, observer-blind, randomized, multi-country immunogenicity trial to evaluate the non-inferiority of the immune response and evaluate safety in participants aged 50 to 59, including those at increased risk for RSV-LRTD compared to older adults aged 60 years and above after a single dose of GSK’s RSV vaccine.</p>\n<p>The study assessed the immune response in participants aged 50 to 59 with pre-defined stable chronic diseases leading to an increased risk for RSV disease (n=570). Immune responses in a broader group of participants aged 50-59 years without these pre-defined chronic diseases (n=570) were also evaluated compared to adults aged 60 and older (n=380). The trial’s primary endpoints were RSV-A and RSV-B neutralization titers of both groups at one month after the vaccine administration compared to adults aged 60 and older. There were also safety and immunogenicity secondary and tertiary endpoints. Safety and reactogenicity data were consistent with results from the initial AReSVi-006 data read out. The most common local adverse event was pain. The most common systemic adverse events were fatigue, myalgia, and headache, which were largely transient and mild to moderate in intensity.</p>\n<p>Results from this trial have been presented at the ACIP meeting of October 2023 and at ReSVinet in February 2024, and have been published in a peer-reviewed medical journal. The data are being submitted to other regulators to support potential label expansions.</p>\n<p><strong>About the NCT04886596 trial</strong></p>\n<p><em>Arexvy</em> is the only RSV vaccine with efficacy and safety data available through three full seasons. These new data from the AReSVi-006 (Adult Respiratory Syncytial Virus, NCT04886596) were presented at the CHEST Annual Meeting, organized by the American College of Chest Physicians, on October 8, 2024.</p>\n<p><strong>About RSV in adults</strong></p>\n<p>RSV is a common contagious virus affecting the lungs and breathing passages. Adults can be at increased risk for RSV disease due to comorbidities, immune compromised status, or advanced age.<sup>8</sup> RSV can exacerbate conditions, including COPD, asthma, and chronic heart failure and can lead to severe outcomes, such as pneumonia, hospitalization, and death.<sup>8</sup> According to studies conducted in the US, RSV is estimated to cause approximately 177,000 hospitalizations in adults 65 years and older<sup>6</sup> and 42,000 in adults aged 50-64 years old.<sup>4</sup></p>\n<p>The Product Monograph, posted at www.ca.gsk.com, should be consulted for complete administration and safety information.</p>\n<p><strong>About GSK </strong></p>\n<p>GSK is a global biopharma company with a purpose to unite science, technology, and talent to get ahead of disease together.
