PHILADELPHIA - GSK plc (LSE/NYSE: GSK) revealed new data from its phase III trial for the AREXVY (Respiratory Syncytial Virus Vaccine, Adjuvanted) vaccine, indicating sustained efficacy over three respiratory syncytial virus (RSV) seasons in adults aged 60 and above. The findings, presented at the CHEST 2024 Annual Meeting, show that a single dose of the vaccine maintained a cumulative efficacy of 62.9% against RSV lower respiratory tract disease (RSV-LRTD) and 67.4% against severe RSV-LRTD.
AREXVY, the first RSV vaccine to be approved, has demonstrated continued protection, with efficacy rates of 48.0% in the third season against RSV-LRTD. The vaccine's safety profile remained consistent with previous phase III results, with the most common adverse events being pain at the injection site and fatigue.
The trial included participants with underlying medical conditions, who are at a higher risk for severe RSV-related complications. The vaccine's efficacy in this subgroup was also notable, potentially offering significant public health benefits by reducing hospitalizations and severe outcomes. GSK plans to continue providing data to health authorities to inform future revaccination schedules.
RSV is a significant cause of respiratory illness worldwide, with an estimated 64 million people affected annually. In the United States alone, RSV leads to approximately 177,000 hospitalizations and 14,000 deaths among adults aged 65 and older each year.
Tony Wood, GSK's Chief Scientific Officer, expressed optimism about the vaccine's potential to protect millions of older adults at risk of RSV disease. This announcement is based on a press release statement and the data will be submitted for scientific peer-review as well as regulatory review.
