London, United Kingdom

The global pandemic has put the term mRNA on lips worldwide, but vaccines apart, the field of RNA therapeutics has failed to overcome the problem of delivery and is stuck at first base, targeting the liver. Newco Sixfold Bioscience Ltd. is the latest company working to end this constraint, applying a mixture of computation and advanced chemistry to design tissue-specific RNA delivery systems.”

Sixfold Bioscience is a venture-backed preclinical-stage biotechnology company, founded in 2017, based at the Translation & Innovation Hub in White City, London. Sixfold develops programmable drug delivery systems, with a current focus on siRNA and ASO.

Sixfold’s RNA delivery platform, Mergo®, was conceived by co-founders Dr Perdrix Rosell and Dr George Foot, who were left frustrated by current delivery systems that were either too toxic or faced complex engineering challenges. The Company’s differentiated approach is based on engineering biocompatible nano-architectures with precise chemical profiles that guide the RNA to selected organs.
