Clinical Trials

1 Many clinical trials are done to see if a new drug or device is safe and effective for people
to use .Sometimes clinical trials are used to study different ways to use the standard
treatments so they will be more effective,easier to use,and/or decrease side effects.
Sometimes,studies are done to learn how to best use the treatment in a different group,
such as children,in whom the treatment was not previously tested.
2 It is important to test drugs and medical products in the people they are meant to help,It
is also important to conduct research in a variety of people because different people may
respond differently to treatments.Some people participate in clinical trials because they
have exhausted standard treatment options.Other people participate in trials because they
want to contribute to the advancement of medical knowledge.
3 The FDA（食品及药物管理局）works to protect participants in clinical trials and to
ensure that people have reliable information as they decide whether to join a clinical trial.
Although efforts are made to control the risks to clinical trial participants,some risks may be
unavoidable because of the uncertainty inherent（内在的）in medical research studies
involving new medical treatments.
4 People should learn as much as possible about the clinical trials that interest them.They
should also feel comfortable discussing their questions and concerns with members of the
health care team. Prospective（预期的）participants should understand what happens
during the trial,the type of health care they will receive,and any costs to them.Anyone
considering a clinical trial should also know that there are benefits and risks associated with
participating.
