- Developing and testing a new drug
- Takes a long time (up to twelve years) and can cost a lot of money (around £350 million!)
- First researchers target a disease and make lots of possible new drugs

- Next they're tested on animals to find out about doses and side effects
- Then tested on human volunteers in lab. First on healthy people to look for side effects
- Then on unhealthy people to see if it cures the disease
- If it is safe and effective then bigger clinical trials take place to find the optimum dose
