What is a late phase clinical trial?

There are usually four phases to clinical research in humans which can be categorised as early or late phase. Early phases involve the development, early testing, and safety of a drug, medical device, or treatment protocol whereas late phase trials look at the long-term safety and efficacy of the treatment within a large cohort of patients over a longer period of time.

At the PRC we undertake late phase trials which focus on common chronic conditions which are prevalent in our local community and usually managed within a primary care setting.
