Nangibotide is a synthetic and inhibitory triggering receptor expressed on myeloid cells-1 (TREM-1) peptide, with potential anti-inflammatory and immunomodulatory activities. Upon administration, nangibotide binds to TREM-1 ligand and inhibits the binding of the TREM-1 ligand to TREM-1. This blocks the TREM-1-mediated amplification of innate immunity signaling, and prevents the production of pro-inflammatory mediators and inflammation. TREM-1, an immune-receptor expressed in neutrophils, mature monocytes, macrophages, natural killer (NK) cells and endothelial cells, is up-regulated following Toll-Like Receptors (TLR) or NOD-like receptors (NLR) signaling. It plays a key role in the amplification of inflammatory and innate immune responses.

4.1 MeSH Pharmacological Classification

Anti-Inflammatory Agents

Substances that reduce or suppress INFLAMMATION. (See all compounds classified as Anti-Inflammatory Agents.)

4.2 Mechanism of Action

Nangibotide targets the immunoreceptor TREM-1 (triggering receptor expressed on myeloid cells-1), and has been explored in treating inflammatory disorders like septic schock. Safety and pharmacokinetics studies have shown Nangibotide to be safe and well-tolerated in humans, while animal septic shock models have shown its ability to restore vascular function and improve survival. As of July 2020, Inotrem is recuriting patients to study Nangibotide's effects on patients with COVID-19 and systemic inflammation (NCT04429334).
