Description

ISS 1018 is a short, synthetic, unmethylated CpG oligodeoxynucleotide (CpG ODN) with immunostimulatory activity. ISS 1018 signals through Toll-like receptor 9 (TLR9) to induce the production of immunoglobulin by B cells and interferon (IFN) -alpha, IFN-beta, interleukin-12 (IL-12), and tumor necrosis factor - alpha (TNF-alpha) by plasmacytoid dendritic cells (pDC). ISS 1018 CpG ODN promotes antigen presentation and co-stimulatory molecule expression. ISS 1018 is currently being investigated in combination with HBsAg vaccine as a prophylactic treatment for to prevent Hepatitis B in adults. It is also being investigated in combination with rituximab for treatment of b-cell or non-hodgkin's lymphoma.

Pharmacology

Indication

Investigated for use/treatment in colorectal cancer, hepatitis (viral, B), and lymphoma (non-hodgkin's). ISS 1018 is currently being investigated in combination with HBsAg vaccine as a prophylactic treatment for to prevent Hepatitis B in adults. It has also been investigated in combination with rituximab for treatment of b-cell or non-hodgkin's lymphoma.

Pharmacodynamics

ISS 1018 is a short, synthetic CpG oligodeoxynucleotide (CpG ODN) with immunostimulatory activity. ISS 1018 is an unmethylated CpG motifs in which regions of genomic DNA containing the cytosine-guanine dinucleotide does not show methylation of cytosine. ISS 1018 signals through Toll-like receptor 9 (TLR9) to induce the production of immunoglobulin by B cells and interferon (IFN) -alpha, IFN-beta, interleukin-12 (IL-12), and tumor necrosis factor - alpha (TNF-alpha) by plasmacytoid dendritic cells (pDC). ISS 1018 CpG ODN also promotes antigen presentation and co-stimulatory molecule expression.

Mechanism of action

ISS 1018 signals through Toll-like receptor 9 (TLR9) to induce the production of immunoglobulin by B cells and interferon (IFN) -alpha, IFN-beta, interleukin-12 (IL-12), and tumor necrosis factor - alpha (TNF-alpha) by plasmacytoid dendritic cells (pDC). pDC and IFN-alpha and -beta then induce natural killer (NK) cell proliferation, NK cell production of IFN-gamma, and NK cell-mediated cytotoxicity. Secreted IFNs also stimulate bystander T cell activation and differentiation of naive CD4+ T cells into T-helper 1 cells on specific antigen challenge.
