Biotech firm Oxford Biomedica has been given a multi-million pound boost after one of its key vaccines was given the green light to continue testing.

The Data Safety Monitoring Board has ruled that Trovax, which is undergoing Phase III tests for kidney cancer, can continue the trials without modification.

And this has triggered a milestone payment worth 10m euros (£7.6m) for the company based at the Oxford Science Park which is developing the vaccine in a £350m partnership with pharmaceutical firm Sanofi-Aventis.

Professor Alan Kingsman, chief executive of Oxford BioMedica, said: "The DSMB's recommendation to continue the TRIST study is another important step in the Phase III development of TroVax.

"The trial is on track to complete patient enrolment before the end of this quarter and we anticipate final results in 2009."
