A BCMA-mRNA vaccine is a promising therapeutic for multiple myeloma.

Abstract

Cancer vaccines are emerging as promising therapies to not only prevent cancer but to treat cancer. Here, we developed a therapeutic vaccine for multiple myeloma (MM) using B-cell maturation antigen (BCMA) protein as a target. Given the remarkable efficacy of COVID-19 messenger RNA (mRNA) vaccines, we first packaged sequence- and base-optimized BCMA mRNA into lipid nanoparticles (LNPs) using next-generation ionizable lipid, enhancing their accumulation in the spleen. A toll-like receptor 3 agonist, polyinosinic:polycytidylic acid [poly(I:C)], was also encapsulated in LNPs to further elicit BCMA-specific immune response. BCMA-mRNA LNPs were internalized by dendritic cells (DCs) in vitro, triggering proliferation and activation of BCMA-specific CD8+ cytolytic T cells (CTLs).
