Simon will be speaking at the ICR Annual Conference in London on May 14th 2012, where he will speak on the transferability of foreign data, asking whether the current standard methods of subgroup analyses and bridging studies provide sufficiently robust information when looking to apply clinical trial data generated in one region to prescribing decisions elsewhere in the world.
