CpG ODNs
CpG ODNs are short synthetic single-stranded DNA molecules containing unmethylated CpG dinucleotides in particular sequence contexts (CpG motifs). CpG ODNs possess a partially or completely phosphorothioated (PS) backbone, as opposed to the natural phosphodiester (PO) backbone found in genomic bacterial DNA.
Three major classes of stimulatory CpG ODNs have been identified based on structural characteristics and activity on human peripheral blood mononuclear cells (PBMCs), in particular B cells and plasmacytoid dendritic cells (pDCs). These three classes are Class A (Type D), Class B (Type K) and Class C.CpG-A ODNs are characterized by a PO central CpG-containing palindromic motif and a PS-modified 3’ poly-G string. They induce high IFN-α production from pDCs but are weak stimulators of TLR9-dependent NF-κB signaling and pro-inflammatory cytokine (e.g. IL-6) production. CpG-B ODNs contain a full PS backbone with one or more CpG dinucleotides. They strongly activate B cells and TLR9-dependent NF-κB signaling but weakly stimulate IFN-α secretion. CpG-C ODNs combine features of both classes A and B. They contain a complete PS backbone and a CpG-containing palindromic motif. C-Class CpG ODNs induce strong IFN-α production from pDC as well as B cell stimulation.

Vidutolimod (CMP-001) is a virus-like particle containing a TLR9 activator. Vidutolimod induces human peripheral blood mononuclear cells to secrete IFNα, and upregulates the gene expression of CXCL10, PDL1, IDO and CD80. Vidutolimod activates TLR9, which in turn triggers plasmacytoid dendritic cell activation, production of IFNγ and TNFα, induction of CXCL10, and recruitment of antitumor T cells. Vidutolimod causes influenza-like symptoms, hypotension and tumor regression, and its activity depends on the presence of anti-Qβ antibodies. Vidutolimod modulates monocyte function, promotes CD4 T cell proliferation, and activates multiple immune cell types in an environment with anti-Qβ antibodies. Vidutolimod prolongs the survival of tumor-bearing mice. Vidutolimod is used in research related to advanced melanoma, head and neck squamous cell carcinoma, and advanced non-small cell lung cancer.
