About Circio

Building next generation RNA technology for nucleic acid medicine

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

platform for novel DNA, RNA and viral therapeutics. The proprietary circVec

technology is based on a modular genetic cassette design for efficient

biogenesis of multifunctional circRNA inside cells, which can be deployed in

multiple therapeutic settings, including genetic medicine, cell therapy and

chronic disease. The circVec platform has demonstrated up to 15-fold enhanced

and more significantly more durable protein expression vs. classic mRNA vector

systems and has the potential to become a new gold-standard platform technology

for nucleic acid and viral therapeutics in the future. The circRNA R&D

activities are being conducted by the wholly owned subsidiary Circio AB based at

the Karolinska Institute in Stockholm, Sweden.

In addition, Circio is developing a pan-RAS cancer vaccine, TG01, targeting KRAS

driver mutations. TG01 is currently being tested in two clinical trials: RAS

-mutated pancreatic and lung cancer in the USA and multiple myeloma in Norway.

These studies are being run through academic and industry collaborative

networks, supported by prestigious research grants from Innovation Norway and

the Norwegian Research Council, creating read-outs and future optionality for

the program at low cost to Circio.
