Circio Holding ASA has established technical in vivo proof of concept for its proprietary Circvec circular RNA platform by demonstrating statistically significant improvement in durability over mRNA-based expression.
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.
Laronde Inc., a company developing a new class of closed-loop RNA constructs for future medicines, has raised $440 million in series B financing. Unfurling at a pivotal moment for RNA-based therapies and vaccines, the company's approach is a bet on early evidence that its "endless" RNA loops can produce stable, enduring and tunable protein expression to fight disease.
