Researchers from Shanghai Institute of Nutrition and Health and Guangming Advanced Research Institute (China) proposed a new strategy based on a circular RNA (circRNA) encoding human relaxin-2 (cRLN2). circRNAs, thanks to their high stability and low immunogenicity, have been proposed as promising new drugs for several applications.
The mRNA technology used in vaccines against viral infections could also be developed for cancer therapies. A group of scientists has designed a circular RNA (circRNA) encapsulated in lipid nanoparticles (LNPs) that acts in the mitochondria of tumor cells through the protein gasdermin-D (GSDMD) and reduces adenocarcinoma. The work was published on Oct. 16, 2023, in Nature Cancer.
Orna Therapeutics Inc., which is pioneering a novel circular RNA protein expression technology in several therapeutic areas, has achieved lift-off. The Cambridge, Mass.-based company has closed a broadly based alliance in infectious disease and oncology with Merck & Co. Inc., under which it is getting $150 million up front and up to $3.5 billion in development, regulatory and sales-based milestones. In addition, Merck, of Rahway, N.J., is investing another $100 million in Orna’s equity, as part of its $221 million series B round, which the company also disclosed on Aug. 16.
