lipid nanoparticle encapsulated mRNAs encoding human IL-12A/IL-12B MEDI-1191
A formulation consisting of lipid nanoparticle encapsulated messenger RNA (mRNA) encoding human interleukin-12 subunit beta (IL-12B; IL-12 subunit p40) and interleukin-12 subunit alpha (IL-12A; IL-12 subunit p35) with potential immunomodulatory and antineoplastic activities. Although the exact mechanism of action has not been completely characterized, upon intratumoral injection, the lipid nanoparticle moiety presumably binds to the plasma membrane of nearby cells and releases the IL-12A and IL-12B mRNA into the cell. The mRNA is then translated by the cellular protein translation machinery to produce a single-chain fusion protein of IL-12B and IL-12A subunits, which is secreted into the local tumor microenvironment (TME). Secretion of IL-12 activates the immune system by promoting the secretion of interferon-gamma, activating natural killer cells (NKs), and inducing cytotoxic T-cell responses, which may result in both decreased tumor cell proliferation and enhanced immune-mediated destruction of tumor cells. Check for active clinical trials using this agent. (NCI Thesaurus)
