Eligibility: Deciding if a person is qualified to join a clinical trial
Phases: Stages
Placebo: Dummy tablet
Protocol: A written plan for the clinical trial
Study sample: People to be studied in the clinical trial
Volunteers: People willing to join the trial
Clinical Trials & Research 4
What is a Clinical Trial?
Identify a health question.
Develop a plan.
Enroll volunteers and follow the plan.
Study the information collected.
Share the results with others.
Improve treatment.

Ethics Committees
The ethics committee reviews a protocol before the study is allowed to start. Their job is to ensure that the risks of being in the study are not greater than the potential benefit.

Data Safety and Monitoring Boards (DSMB) The job of the DSMB is to monitor the
study for any problems with the safety or effectiveness of the medicines.
Clinical Trials & Research 17
Safety
A protocol must describe known risks or side effects and exactly what will be done to protect and monitor patients.
Clinical Trials & Research 18
Schedule of Events
To evaluate the effect of the medicine on their health, all patients in a trial have certain tests or procedures at regularly scheduled intervals.
