Circio presents results that further validate the circVec circular RNA platform at two international industry conferences
Oslo, Norway 5 March 2025 – Circio Holding ASA (OSE: CRNA), a biotechnology company developing powerful circular RNA technology for next generation nucleic acid medicine, today announces that CEO Dr. Erik Digman Wiklund and CSO Dr. Victor Levitsky are presenting updated data demonstrating the significant advantages of Circio’s circular RNA circVec platform compared to current mRNA-based vector technology. The data further strengthens the in vitro and in vivo validation of Circio’s platform. The presentations are being delivered at two major biopharma industry conferences in Basel, Switzerland, and Stockholm, Sweden.
The presentations detail the advantages and potential of the circVec 3.0 generation to improve on current mRNA-based technology for a range of therapeutic applications. In vivo expression data has shown an estimated circRNA half-life of over 600 hours vs. under 10 hours for linear mRNA, which translates to over 70 times prolonged RNA durability and 15 times enhanced protein expression.
Novel systemic LNP-delivery data demonstrates robust and durable circVec expression in spleen, far outperforming equivalent mRNA-vectors. This important finding has the potential to open up attractive therapeutic opportunities for the circVec technology in several areas, such as cell therapy. Further experimental work is currently ongoing to validate and characterize these observations.
“The recent results showing efficient and specific circVec delivery to spleen are very promising and hints at novel opportunities for our circular RNA platform in cell and immune therapies,” said Dr. Victor Levitsky, CSO of Circio. “A broad set of experiments to further investigate this observation, as well as in vivo testing of the novel circVec 3.0 generation, will read out over the next 6-12 weeks. The performance of circVec 3.0-AAV constructs is of particular interest, which we believe has the potential to transform current gold-standard AAV gene therapy and generate substantial partnering interest.”
