About Circio
Building circular RNA expression systems for enhanced gene and cell therapies

Circio Holding ASA is a biotechnology company developing powerful circular RNA vector expression technology for next generation nucleic acid medicine.

Circio has established a unique circular RNA (circRNA) vector expression technology for next generation RNA, DNA and viral therapeutics. The proprietary circVec platform is based on a modular genetic cassette design for efficient biogenesis of multifunctional circRNA inside cells. The circVec platform has applications in multiple therapeutic settings, including genetic medicine, cell therapy and chronic disease. It has demonstrated over 70-fold prolonged RNA half-life and up to 15-fold enhanced protein expression vs. conventional mRNA vector systems in vivo, and has the potential to become a new gold-standard protein expression technology. The circRNA R&D activities are being conducted by the wholly owned subsidiary Circio AB in Stockholm, Sweden.

In parallel, Circio is continuing to develop its legacy immuno-oncology program, TG01, through cost-efficient external academic and industry collaborations. TG01 targets RAS-mutated cancers and is being tested in two clinical trials in Norway and the USA. TG01 is a therapeutic peptide vaccine adjuvanted by STIMULON QS-21 licensed from Agenus Inc.
