BCG-STING
BCG-STING is a recombinant BCG strain that overexpresses the small molecule STING agonist cyclic di-AMP. For prevention of Mtb proliferation BCG-STING is more potent than standard BCG in mouse, guinea pig, and NHP models, and it is also safer than BCG-WT in mouse models. BCG-STING can be produced by fermentation, overcoming current BCG production limitations.

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.

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.

rBCG-LTAK63 is an unmarked recombinant BCG strain expressing the subunit A of detoxified E. coli Heat-Labile Toxin (LTAK63) as adjuvant. rBCG-LTAK63 induced protection superior to standard BCG, through enhanced and regulated Th1/Th17 responses, and both early effector and long-term TRM cell responses with reduced lung inflammation and improved immunopathological control.

The parental candidate is an isogenic mutant in Mtb CDC1551 gene Rv3223c (sigH). We have now generated multiple Mtb double and triple knock-out (DKO, TKO) strains including: DsigHDsecA2DsodA, DsigHDfbpADsapM, DsigHDleuCDpanCD, DsigHDmetA, DsigHDmce4EDmce4F, DsigHDfadD29, DsigHDhadC, DsigHDRv3683, DsigHDmce1A, DsigHDcobM.
