Phase II (Clinical trial)

Phase II trials attempt to find out whether the new treatment works well enough for a phase III trial as well as more about possible side effects and further information about the best dose. They are larger than phase I trials and usually have around 100 participants.

Phase III (Clinical trial)

Phase III trials compare the new treatment with the best currently available treatment with the aim of attempting to find out which one works better as well as how the treatment affects the participant’s quality of life.

Phase III trials have more participants than phase I or phase II with sometimes as many as a thousand people. Most phase III trials are randomised.

Phase IV (Clinical trial)

Phase IV trials are often completed after the drug has been shown to work and has been licenced.

They aim to find out what the long terms risks and benefits are of the new treatment.
