In the UK, it takes over 12 years to develop a new medicine to the standards of quality, efficacy and safety laid down by legislation. It typically costs £1.15 billion to do all the research and development necessary before a new medicine can be licensed for use.

The majority of medicines under development never make it to the market; following thorough studies, they may be found to have unacceptable side effects, or they don’t work any better than existing treatments.
