Clinical Trial and its Purpose

Clinical trials / research studies gives a clinician many answers to questions from the point of prevention, detection, diagnosis, control and treatment of illness or a condition such as cancer. It is used not only in relation to a new drug but also to study equipments, devices, treatments, interventions etc.

• How helpful the treatment is?
• How does the experimental drug or new type of treatment work?
• If it works better than already existing treatment options?
• What are the side effects that occur as a result of the new treatment/ drug?
• How serious the side effects are when compared to standard treatment options?
• Do the benefits outweigh the side effects?
• Which groups of people are most likely to benefit from the new drug / treatment?
