Guildford, UK, 5 August 2005: ReNeuron Group plc (“ReNeuron” or the “Company”), the UK-based adult stem cell company, today announces that it has successfully completed its flotation on AIM (“Alternative Investment Market”).

Details of the flotation

  • ReNeuron is raising £9.5 million through a placing and private placement in both the US and UK. A total of 38 million shares, all of which are new ordinary shares, are being issued by the Company at 25 pence per share.
  • In addition to the funds raised in the flotation, the Company has also issued 19 million warrants, exercisable by 12 February 2007 at 30 pence, a 20% premium to the placing price. If exercised, these warrants will raise a further £5.7 million for the Company.
  • It is expected that dealings in the Company’s ordinary shares will commence on AIM at 08.00 on 12 August 2005 under the ticker symbol RENE.L.
  • 93.5 million shares will be in issue immediately following the flotation, corresponding to a market capitalisation of approximately £23.4 million.
  • The net proceeds will be used to fund the first clinical trials with respect to ReNeuron’s lead ReN001 stroke programme. Initial clinical data from this trial is anticipated in 2007. The proceeds will also be used to fund ongoing research and pre-clinical development of the Company’s other therapeutic programmes.
  • Collins Stewart acted as NOMAD in the UK, and Harris Nesbitt Corp. acted as placement agent in the US.

Commenting on the announcement, Michael Hunt, Chief Executive Officer of ReNeuron, said:

“We are delighted to have successfully completed the flotation, and to raise the funds that we were seeking, in such challenging market conditions. The funds raised provide us with the financial resources to progress our programmes to key milestone points, and most importantly our lead ReN001 stroke programme into the clinic. The warrants offer the prospect of additional funding at relatively low cost. This will further bolster ReNeuron’s cash resources as the stroke programme moves towards proof of principle in man.”

Notes to editors

ReNeuron is a leading, UK-based adult stem cell therapy business. The Company 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. The Company is also exploiting the non-therapeutic potential of its technologies with the intention of generating sustainable near-term revenue streams to contribute to the funding of its therapeutic programmes. The Company is planning to file for approval to commence initial clinical trials with its stem cell therapy for stroke in the first half of 2006, and hopes to commence these trials as soon as possible thereafter.

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

The Company has tested a number of its neural stem cell lines in a series of validated pre-clinical efficacy models of stroke and Huntington’s disease, with positive results. The efficacy data are being prepared for publication in a leading peer-reviewed journal and were presented at the Society of Neuroscience and American Neurological Association meetings in October 2004. To the best of the Directors’ knowledge, this was the first disclosure of positive pre-clinical data in stroke using stable, expanded neural stem cells, thus providing evidence of the Company’s strong competitive position in the field.

As a result of this progress, the Company’s lead stem cell therapeutic program, ReN001 for chronic stroke disability, has now moved into late pre-clinical development. The ReN001 cell product has been banked to Good Manufacturing Practice (GMP) standards, and pre-clinical safety studies are underway. Initial feedback from the US Food and Drug Administration has been encouraging. ReNeuron plans to commence initial clinical trials in stroke in the first half of 2006, with trials commencing as soon as possible thereafter.

In addition to its ReN001 stroke programme, ReNeuron has broadened its product pipeline by initiating programmes to develop stem cell therapies to address Huntington’s disease, Parkinson’s disease, Type 1 diabetes and diseases of the retina.

The Company recently announced that it had entered into an agreement with StemCells, Inc., a leading US adult stem cell development company, giving that company exclusive access to ReNeuron’s c-mycER technology for use in the development of therapies for certain diseases targeted by StemCells. In return, ReNeuron gains exclusive access to StemCells’ adult neural stem cell patent portfolio for the development of its own neural stem cell therapies. The agreement provides for reciprocal royalties and milestone payments on the achievement of various goals under the cross-licence.

The potential market for stem cell and tissue engineering products is estimated to exceed $10 billion by 2013* and the diseases targeted by ReNeuron are chiefly characterised by large patient populations representing a major healthcare cost in terms of existing patient care. For most of the Company’s targeted indications, there are currently no effective cures or treatments addressing the underlying cause of the condition.

ReNeuron has also leveraged its stem cell technologies into non-therapeutic areas such as drug discovery � its ReNcell product.
