The extraordinary success of the creation of vaccines for Covid-19 has made the business of clinical trials look simple. But appearances can be deceptive and it usually takes many years and costs hundreds of millions of pounds to bring a new drug, therapy or medical device successfully to market.

How far is greater collaboration - with start-ups partnering with big pharma and research companies - changing the way in which trials operate? And will new tech developments - like the greater, tailored use of Artificial Intelligence, digital data and advanced statistical techniques - make the process cheaper and quicker - while compromising neither safety nor patient confidentiality?
