EUA Filed for Covid Prevention in Immunocompromised
Invivyd says it is seeking FDA emergency use authorization for VYD222, which is described as a “broadly neutralizing, half-life extended monoclonal antibody candidate for the pre-exposure prevention of Covid-19 in immunocompromised adults and adolescents.” The submission is based on “positive initial results” from the CANOPY Phase 3 pivotal clinical trial, as well as ongoing in vitro neutralization activity against relevant Covid variants, it says.
Recent results from the CANOPY trial demonstrated that VYD222 produced high serum virus-neutralizing antibody (sVNA) titer levels against XBB.1.5 variant in the immunocompromised cohort, the company says. “Initial results showed that the safety and tolerability profile of VYD222 remained favorable with no study drug-related serious adverse events reported; adverse events attributed to VYD222 were Grade 1 or 2 (mild or moderate) in severity,” it adds.
Invivyd notes that there are more than 9 million immunocompromised people in the U.S. who may not adequately respond to a Covid-19 vaccination, which increases their risk for severe outcomes if infected. It adds that there are no monoclonal antibodies authorized or approved in the U.S. for preventing symptomatic Covid-19.
