Research study Clinical trials

Many new medicines and treatments are found to be helpful and safe in test tubes and in animals. They must also prove safe and effective in humans before doctors can prescribe them. This testing in humans is permitted only if that person volunteers for participation and understands the risks and benefits of taking part in a study. This informed consent to participate must be based on the volunteer's understanding of what is involved in the study, including potential risks and benefits. Volunteers may leave a study at any time.
