Weighing potential benefits and risks of clinical trials
Although designed to benefit tomorrow’s patients, clinical trials
often help today’s patients as well. According to the Maryland Parkinson
disease and Movement Disorders Center, “People who participate in
clinical trials tend to do better than those who do not.”
What benefits might you realize by participating in a clinical
trial?
- An opportunity to become actively involved in your own health
care.
- Access to the latest research and treatments before they are
available to the general public.
- Investigational treatments may be safer or more effective than
the standard treatment.
- Another option when standard therapy has failed or stopped
working.
- Obtain free, expert medical care from a research team at a
leading health care facility throughout the trial.
- An opportunity to help others by advancing scientific knowledge
and the understanding and treatment of PD. Without patients who are
willing to participate in clinical trials, developing more effective
treatments would be impossible.
What are the potential risks associated with clinical trials?
Institutional Review Boards (IRB) must approve and monitor all
clinical trials that involve human participants to make sure the
risks are as low as possible and are worth any potential benefits.
These independent groups of doctors, researchers, community
advocates, and others ensure that the rights of the study
participants are protected. |

Clinical trials, however, are still experiments, and as such
involve risks. These include the possibility that:
- The investigational treatment may not be effective for the
participant.
- New drugs under study are not always better -- and could be
worse -- than the standard care to which they are being compared.
- New treatments may have unexpected side effects that are
unpleasant, serious, or even life-threatening.
- Participants may be required to make more visits and undergo
more procedures than they would if they were not in the clinical
trial
