Abstract B041: A novel nanoparticular formulated tetravalent RNA cancer vaccine for treatment of patients with malignant melanoma

Abstract Immunotherapeutic approaches have evolved as promising and valid alternatives to available conventional cancer treatments. Amongst others, vaccination with tumor antigen-encoding RNAs by local administration is currently successfully employed in various clinical trials. To allow for a more efficient targeting of antigen-presenting cells (APCs) we have developed a novel RNA immunotherapeutic for systemic application based on a fixed set of four liposome complexed RNA drug products (RNA(LIP)) each encoding one shared melanoma-associated antigen. Similar to other liposomal drugs, the four injectable RNA(LIP) products constituting the investigational medicinal product will be prepared …
