Oxford BioMedica: Clinical Trial Update


Oxford, UK - 3 June 2013: Oxford BioMedica ("Oxford BioMedica" or "the Company") (LSE: OXB), the leading gene-based biopharmaceutical company, today announces that it has voluntarily paused recruitment into the RetinoStat® Phase I, StarGen™ Phase I/IIa and UshStat® Phase I/IIa studies, as a precautionary measure, whilst the Company investigates the recent detection of very low concentrations of potential impurities derived from a widely-used third party raw material.


A new, highly sensitive test method has recently been introduced into the Company's wide range of analytical methods and quality assurance processes used for routine batch testing.  Using this method, potential impurities have been detected at very low concentrations in clinical trial material.  No safety concerns relating to any of the aforementioned products have been identified in any pre-clinical and clinical data generated to date and there is no reason to believe that the favourable safety profile of these products will be affected. 


Such precautionary measures are routine and Oxford BioMedica is working very closely with the regulatory authorities to complete its investigations.  The Company is committed to resuming the clinical trials as soon as possible and will continue to keep the market informed as appropriate.
