Tevogen reports TVGN 489 retains activity against FLiRT strains of SARS-CoV-2

Tevogen announced TVGN 489, its investigational allogeneic SARS-CoV-2 specific Cytotoxic CD8+ T lymphocytes, or CTLs, immunotherapy for treatment of COVID-19 in high-risk patients and Long COVID, retains activity against the currently dominant and highly mutated FLiRT strains of SARS-CoV-2 based on a review of this variant’s protein sequences. Named FLiRT to reflect amino acid changes occurring in the spike protein, these Omicron subvariants are descendent from JN.1, the previously dominant strain in the U.S. TVGN 489 contains Cytotoxic T lymphocytes that recognize multiple SARS-CoV-2 proteins, or peptides. TVGN 489’s peptide targets have been preserved in all previously studied COVID strains. Continuing surveillance by Tevogen Bio of SARS-CoV-2 variants, show that 95% of these CTLs remain active against FLiRT variants, including KP.2, the current dominant strain.
