About ReNeuron

ReNeuron is a leading, UK-based stem cell therapy business. It is applying its novel stem cell platform technologies in the development of ground-breaking stem cell therapies to serve significant and unmet or poorly-met clinical needs.

ReNeuron has used its c-mycER technology to generate genetically stable stem cell lines from non-embryonic tissue sources. This technology platform has multi-national patent protection and is fully regulated by means of a chemically-induced safety switch. Cell growth can therefore be completely arrested prior to in vivo implantation.

ReNeuron has filed for approval to commence initial clinical studies in the US with its lead ReN001 stem cell therapy for chronic stroke disability. This represents the world’s first such filing concerning a neural stem cell treatment for a major neurological disorder. There are an estimated 50 million stroke survivors worldwide, approximately one half of which are left with permanent disabilities. The annual health and social costs of caring for these patients is estimated to be in excess of £5 billion in the UK and in excess of US$50 billion in the US.

ReNeuron has also generated pre-clinical efficacy data with its ReN005 stem cell therapy for Huntington’s disease, a genetic and fatal neurodegenerative disorder that affects around 1 in 10,000 people. This programme is in pre-clinical development. In addition to its stroke and Huntington’s disease programmes, ReNeuron is developing stem cell therapies for Parkinson’s disease, Type 1 diabetes and diseases of the retina.

ReNeuron has also leveraged its stem cell technologies into non-therapeutic areas � its ReNcell®range of cell lines for use in research and in drug discovery applications in the pharmaceutical industry. ReNeuron’s ReNcell®CX and ReNcell®VM neural cell lines are marketed worldwide under license by Millipore Corporation.

ReNeuron’s shares are traded on the London AIM market under the symbol RENE.L.
