PNx6

PNx6 is a modular, self-assembling and self-adjuvanting peptide-based vaccine candidate that is cold-chain independent. Each peptide building blocks consist of a linear arrangement comprising a 15-leucine (15L) self-assembly inducer moiety, a 15 amino acid Mtb epitope and a 9 amino acids HLA-E binding moiety, with each moiety separated by a triple lysine spacer.

mRNA-Rv1387-Rv0287-Rv1788

The vaccine consists of three antigens delivered with the mRNA platform. Monovalent antigens were cloned into mRNA constructs containing a 5’ cap, 5’ untranslated region (UTR), 3’ UTR, and a polyadenylation signal, subjected to in vitro transcription using N1-methylpseudouridine, and encapsulated in lipid nanoparticles containing ALC-0315, 18:1 (Δ9-Cis) PE (DOPE), cholesterol, and 14:0 PEG2000 PE.
