Independent evaluation of KP.3.1.

1 and LB.1 variants shows in vitro pseudovirus neutralization potency of PEMGARDA in-line with prior variants tested Proprietary, 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 expected to meaningfully alter pemivibart activity; routine neutralization analysis will follow in ordinary course to assess potential for epistasis or allostery WALTHAM, Mass.

, Sept. 23, 2024 (GLOBE NEWSWIRE) -- Invivyd, Inc. (Nasdaq: IVVD), a biopharmaceutical company devoted to delivering protection from serious viral infectious diseases, today provided detailed virology data supporting previously communicated neutralization activity results, along with a genetic and structural analysis of past and present SARS-CoV-2 variant spike proteins, including the established molecular target of pemivibart.

As part of Invivyd’s ongoing monitoring of antiviral activity, Invivyd contracts with LabCorp’s Monogram Biosciences lab to provide independent, robust virology assessments in a consistent lineal chain that allows for consideration of potential changing pemivibart potency as SARS-CoV-2 evolves. Pemivibart potency against contemporary viruses KP.3.
