PHILADELPHIA–(BUSINESS WIRE<\/a>)–
\nGSK plc (LSE\/NYSE: GSK) today announced that the US Food and Drug Administration (FDA) has approved AREXVY(respiratory syncytial virus vaccine, adjuvanted) for the prevention of lower respiratory tract disease (LRTD) caused by respiratory syncytial virus (RSV) in individuals 60 years of age and older. Thisis the first RSV vaccine for older adults to be approved anywhere in the world.<\/p>\nThis press release features multimedia.

<\/div>\nTony Wood, Chief Scientific Officer, GSK, said: <\/b>\u201cToday marks a turning point in our effort to reduce the significant burden of RSV. AREXVYis the first approved RSV vaccine for older adults, expanding GSK\u2019s industry-leading vaccine portfolio, which protects millions of people from infectious diseases each year. Our focus now is to ensure eligible older adults in the US can access the vaccine as quickly as possible and to progress regulatory review in other countries.\u201d<\/p>\n
\nRSV is a common, contagious virus that can lead to potentially serious respiratory illness. It causes approximately 177,000 hospitalizations and an estimated 14,000 deaths in the US in adults aged 65 years and older each year.1,2,3<\/sup> Older adults, including those with underlying medical conditions such as diabetes and chronic heart and lung disease, are at increased risk of severe RSV illness and drive the majority of RSV hospitalizations.4<\/sup><\/p>\n
John Kennedy, MD, President, American Medical Group Association (AMGA), added:<\/b> \u201cFor decades, AMGA and the healthcare community at large have been active in finding ways to increase adult immunizations. As a result, we are pleased that we can now add a respiratory syncytial virus vaccine to providers\u2019 options for patient care. With this vaccine, Americans over the age of 60, and particularly those with underlying health conditions like COPD, asthma, or congestive heart failure, will have a vaccine to help protect against potentially serious outcomes from RSV.\u201d<\/p>\n
\nThe US FDA approval is based on GSK\u2019s landmark positive pivotal AReSVi-006 (Adult Respiratory Syncytial Virus) phase III trial data. In the trial, the vaccine showed statistically significant and clinically meaningful overall efficacy of 82.6% (96.95% CI, 57.9\u201394.1, 7 of 12,466 vs 40 of 12,494) against RSV-LRTD in adults aged 60 years and older, meeting the primary endpoint. In addition, efficacy was 94.6% (95% CI, 65.9\u201399.9, 1 of 4,937 vs 18 of 4,861) in older adults with at least one underlying medical condition of interest, such as certain cardiorespiratory and endocrine-metabolic conditions. Efficacy against severe RSV-LRTD, defined as an RSV-associated LRTD episode preventing normal, everyday activities, was 94.1% (95% CI, 62.4\u201399.9, 1 of 12,466 vs 17 of 12,494).<\/p>\n
\nThe vaccine was generally well tolerated with an acceptable safety profile. The most frequently observed solicited adverse events were injection site pain, fatigue, myalgia, headache, and arthralgia. These were generally mild to moderate and transient.<\/p>\n
\nIn June 2023, the Advisory Committee on Immunization Practices (ACIP) will make recommendations on the appropriate use of the vaccine in the US. The vaccine will be available for older adults before the 2023\/24 RSV season, which typically starts ahead of the winter months.<\/p>\n
\nIn April 2023, the European Medicines Agency\u2019s Committee for Medicinal Products for Human Use (CHMP) issued a positive opinion recommending the vaccine for the prevention of LRTD caused by RSV in adults aged 60 years and older. A final European regulatory decision is anticipated in the coming months, while regulatory reviews are ongoing in Japan and several other countries.<\/p>\n
About AREXVY (respiratory syncytial virus vaccine, adjuvanted)
\n
<\/b>Respiratory syncytial virus vaccine, adjuvanted, contains a recombinant subunit prefusion RSV F glycoprotein antigen (RSVPreF3) combined with GSK\u2019s proprietary AS01E<\/sub> adjuvant.<\/p>\n\nIn the US, AREXVY is indicated for the prevention of RSV-LRTD in individuals 60 years of age and older. GSK\u2019s RSV older adult vaccine is not currently approved anywhere outside the US. The proposed trade name remains subject to regulatory approval outside the US.<\/p>\n
\nA clinical trial that aims to expand the population who may benefit from RSV vaccination into adults aged 50-59, including participants with underlying comorbidities, is fully recruited. Results are expected in 2023, together with additional results from the AReSVi-006 phase III efficacy trial and the AReSVi-004 immunogenicity trial. These trials continue to evaluate an annual revaccination schedule and protection\/immunogenicity over multiple seasons following one dose of the RSV vaccine. Results from two additional influenza vaccine co-administration trials are also expected before the June 2023 Advisory Committee on Immunization Practices (ACIP) meeting.<\/p>\n
\nThe GSK proprietary AS01 adjuvant system contains QS-21 STIMULON adjuvant licensed from Antigenics Inc, a wholly owned subsidiary of Agenus Inc.<\/p>\n

- \nVaccination with AREXVY may not result in protection of all vaccine recipients.<\/p>\n<\/li>\n<\/ul>\n
About RSV in older adults
\n
<\/b>RSV is a common contagious virus affecting the lungs and breathing passages. Older adults are at high risk for severe disease due in part to age-related decline in immunity, and older adults with underlying conditions are at even greater risk for severe disease. RSV can exacerbate conditions, including chronic obstructive pulmonary disease (COPD), asthma, and chronic heart failure and can lead to severe outcomes, such as pneumonia, hospitalization, and death. Each year, approximately 177,000 adults 65 years and older are hospitalized in the US due to RSV; an estimated 14,000 cases result in death.3<\/sup> For adults 60 and older, data suggest an increased risk for severe RSV infection that can lead to hospitalization.5,6 <\/sup>Adults with underlying conditions are more likely to seek medical services and have higher hospitalization rates than adults without these conditions.<\/p>\nAbout GSK
