Abstract CT034: A first-in-human phase I/II clinical trial assessing novel mRNA-lipoplex nanoparticles for potent melanoma immunotherapy

2017

Abstract Therapeutic vaccination with tumor antigen-encoding RNAs by local administration is currently being successfully employed in various clinical trials. Advancing from local to more efficient systemic targeting of antigen-presenting cells (APCs), we have developed pioneering RNA-lipoplex (RNA(LIP)) immunotherapeutics for intravenous application based on the employment of well-known lipid carriers without the need for functionalization of particles with molecular ligands. The novel RNA(LIP) formulation has been engineered to preserve RNA integrity after intravenous injection and physicochemically optimized for efficient uptake and expression of the encoded antigen by APCs in various ly…
