Independent evaluation of KP.3.1.1 and LB.1 variants shows in vitro pseudovirus neutralization potency of PEMGARDA in-line with prior variants testedProprietary, ongoing SARS-CoV-2 spike analyses demonstrate consistent structural stability of the pemivibart binding site to date, which has routinely predicted sustained pemivibart in vitro neutralization activity Potential emerging variants, such as XEC and LP.1, encode mutations that are distal from the pemivibart binding site, and, therefore, are also not e ...
