$IPA The Company anticipated viral evolution leading to novel SARS-CoV-2 variants of concern throughout the design of their PolyTope SARS-CoV-2 therapeutic cocktail, aiming to minimize the risk of mutagenic escape (a reduction or elimination in the efficacy of a therapy or vaccine by virus mutation). As such, the Company continuously validates, and has demonstrated to date, maintained neutralization potency of IPA's multi-antibody cocktail towards SARS-CoV-2 variants of concern. IPA previously announced that TATX-03 demonstrated strong efficacy in reducing viral load in vivo using a hamster challenge model and potently neutralized pseudovirus of Alpha (B.1.1.7) and Beta (B.1.351) variants in vitro.
