What is a clinical trial?

Clinical trials are a crucial part of the process of developing, licensing and bringing new life-changing, life-saving drugs and therapies to patients. Trials ensure that new treatments are both safe and effective, enabling medical practitioners and patients to use them confidently.

Some clinical trials are conducted to establish whether already-approved drugs can be used to treat different conditions, but most trials are for new drugs and innovations – a completely new way of treating a disease or illness, thereby providing choices and hope for patients.

How are new therapies developed?

New drugs and therapies have to go through extensive testing before they are tested in clinical trials on humans.
