Abstract
Abstract HDT Bio, a Seattle biotech company, has developed a platform technology based on self-amplifying RNA and a proprietary nanoparticle delivery system. mRNA have been increasingly used in the development of vaccines in both infectious diseases and oncology. Especially LNP- delivered mRNA has been deployed, following the success during the COVID pandemic, However, self-ampliying RNA (repRNA) possesses several features of particular relevance to cancer medicine. HDT has developed a nanoparticle technology named LION[TM] to safely and effectively deliver RNA to patients. In vivo studies showed that repRNA not only is capable of delivering robust cell-mediated immune responses but also doing so with a significanlty improved safety profile compared to administration using LNP-based formulations. These data will be presented in the context of clinical safety data with repRNA/LION. Furthermore, repRNA/LION was siuccessfully used to induce robust T-cell responses against tumor antigens, and will be discussed. Citation Format: Peter Berglund.
