Oxford BioMedica Announces Positive DSMB Review of Ongoing RetinoStat® and StarGen™ Clinical Studies

The StarGen™ open label, dose escalation Phase I/IIa study will enrol up to 28 patients and will evaluate three dose levels for safety, tolerability and aspects of biological activity.  In the US, the study is led by Professor David Wilson at the Oregon Health and Science University, Portland, Oregon.  In France, Professor Jose-Alain Sahel leads the study at Centre Hospitalier National d'Ophtalmologie des Quinze-Vingts, Paris.  StarGen™ has received European and US Orphan Drug Designation which brings development, regulatory and commercial benefits.  Further results from this study are expected in Q4 2012.

Notes to editors

1. Oxford BioMedica^®

Oxford BioMedica plc (LSE: OXB) is a biopharmaceutical company developing innovative gene-based medicines and therapeutic vaccines that aim to improve the lives of patients with high unmet medical needs.  The Company's technology platform includes a highly efficient LentiVector^® gene delivery system, which has specific advantages for targeting diseases of the central nervous system and the eye; and a unique tumour antigen (5T4), which is an ideal target for anti-cancer therapy.  Through in-house and collaborative research, Oxford BioMedica has a broad pipeline with current partners and licensees including Sanofi, Pfizer, GlaxoSmithKline, MolMed, Sigma-Aldrich, Biogen Idec, Emergent BioSolutions and ImaginAb.  Further information is available at http://www.oxfordbiomedica.co.uk.

2. LentiVector^® gene delivery technology

Oxford BioMedica's LentiVector^® gene delivery technology is one of the most advanced gene delivery systems currently available, which has many applications in product development and discovery research.  It is the system of choice for gene-based treatments addressing chronic and inherited diseases.  Oxford BioMedica has established a dominant intellectual property estate in the field of lentiviral-vector mediated gene delivery through its in-house research and from work conducted by the Company's co-founders at Oxford University.

3. Oxford BioMedica's agreement with Sanofi

Under the terms of the agreement signed with Sanofi in April 2009, Oxford BioMedica is responsible for the pre-clinical and initial Phase I/II studies of four lentiviral vector-based product candidates in the field of ophthalmology: RetinoStat^® for "wet" age-related macular degeneration, StarGen™ for Stargardt disease, UshStat^® for Usher syndrome 1B and EncorStat^® for corneal graft rejection. Oxford BioMedica will receive committed funding of up to US$24 million over the initial phase of development.  Oxford BioMedica granted Sanofi a license to develop the products and an option for further development, manufacture and commercialisation on a worldwide basis.  At any time prior to or within a defined period after completion of each Phase I/II study, Sanofi can exercise its option to license the products.  On 29 June 2012, Sanofi elected to exercise its options to acquire two exclusive worldwide licences for further development, manufacture and commercialisation of StarGen™ and UshStat^®.  Oxford BioMedica is currently conducting the two ongoing Phase I/IIa trials for StarGen™ and UshStat^®.  The companies will continue to work together to plan the next stages of development and finalise the terms of the worldwide licence agreements.

4. Age-Related Macular Degeneration and RetinoStat^®

Age-related macular degeneration (AMD) is a major cause of blindness affecting an estimated 25 to 30 million people worldwide and the incidence of AMD is expected to triple by the year 2025 (source: AMD Alliance International).  Neovascular "wet" AMD accounts for the majority of all severe vision loss from the disease.  RetinoStat^® delivers two anti-angiogenic genes, endostatin and angiostatin, directly to the retina and aims to preserve and improve the vision of patients through anti-angiogenesis which blocks the formation of new blood vessels.  On the basis of pre-clinical data, it is anticipated that RetinoStat^® may require only a single administration which would give the product a significant advantage in the market over currently available treatments that often require frequent, repeated administration.

5. Stargardt disease and StarGen™

Stargardt disease is the most common juvenile degenerative retinal disease which affects approximately 80-100,000 patients in the US and Europe.  The disease is caused by a mutation of the ABCR gene which leads to the degeneration of photoreceptors in the retina and vision loss. StarGen™ uses the Company's LentiVector^® platform technology to deliver a corrected version of the ABCR gene.  On the basis of pre-clinical data, it is anticipated that a single application of StarGen™ to the retina could potentially either provide long-term or permanent correction.  There are currently no approved treatments available for Stargardt disease.
