ReNeuron Signs Manufacturing Contract With Angel Biotechnology Ltd For Second-Generation CTX Stem Cell Product

Guildford, UK, 10 September 2009: ReNeuron Group plc (LSE: RENE.L) today announces that it has signed a contract with Angel Biotechnology Holdings plc (“Angel”), under which Angel will manufacture clinical-grade lots of a second-generation formulation of ReNeuron’s lead CTX stem cell line, for subsequent pre-clinical and clinical applications.

The new formulation enables the CTX cells to be readily frozen down for shipping and storage, and thawed at the point of use. This process enables a greatly enhanced shelf life for the product and the capability to ship the cells for clinical and commercial application anywhere on the globe. In due course, the Company plans to utilise this enhanced CTX cell formulation for multi-centre, proof-of-concept clinical trials with its ReN001 stem cell therapy for disabled stroke patients, as well as for late pre-clinical testing and initial clinical trials with its ReN009 stem cell therapy for peripheral artery disease. Michael Hunt, Chief Executive Officer of ReNeuron, said:

“We are pleased to have further extended our cell manufacturing collaboration with Angel. Our new CTX cell formulation has shown great promise during in-house development work and this contract marks an important step in realising ReNeuron’s vision to develop a readily scalable and truly commercial stem cell-based therapeutic for wide-scale patient use.“
