GSK Wins Priority Review for Expanded Use of RSV Vaccine

Share

FDA has accepted for priority review a GSK supplemental BLA to extend the indication of its Arexvy adjuvanted respiratory syncytial virus (RSV) vaccine to adults aged 50-59 who are at increased risk for RSV disease. The vaccine is currently approved for adults aged 60 and over for the prevention of lower respiratory tract disease (LRTD) caused by RSV. The agency has set a user fee review action target date of 6/7.

The application is based on data from a Phase 3 trial [NCT05590403] that evaluated the non-inferiority of the immune response in participants aged 50 to 59 at increased risk of RSV-LRTD compared to older adults aged 60 years and above after a single vaccine dose, according to the company. “The trial’s primary endpoints were RSV-A and RSV-B neutralization titres of both groups of 50 to 59 year olds at one month after the vaccine administration compared to adults aged 60 and older,” it says, adding that there were also safety and immunogenicity secondary and tertiary endpoints. GSK plans to present the trial results at an upcoming medical conference.
