Why do we need older people in clinical trials?
Researchers need the participation of older people in their clinical trials so that scientists can learn more about how the new drugs, therapies, medical devices, surgical procedures, or tests will work for older people. Many older people have special health needs that are different from those of younger people. For example, as people age, their bodies may react differently to drugs. Older adults may need different dosages (or amounts) of a drug to have the right result. Also, some drugs may have different side effects in older people than younger people.

Types of Clinical Trials
There are two types of clinical research trials, therapeutic and non-therapeutic.
Individual Drug Studies
Individual drug studies can be conducted at a large or small number of hospitals, depending on the purpose of the trial. In individual drug studies, a drug manufacturer closely monitors lab tests and results from the use of the drug, and releases only a small amount of the drug during the period of the study.
Supportive Care Studies
Supportive care studies evaluate ways of helping with the side effects of treatments. These can also be performed at a few medical centers at a time or at many hospitals at once. Most often though, these research questions can be answered with fewer patients.
Limited Institution Trials
Sometimes, clinical trials are performed in only a few hospitals. These are called Limited Institution Trials and they are able to answer a research question with fewer patients than most national trials require. Answers to important research questions can be obtained in a shorter time through such limited trials.
Pilot studies
Pilot studies are examples of limited institution trials. In these studies, investigators are studying a new treatment or therapy combination. Such studies are done at only a few institutions with a limited number of patients to see if the treatments are safe and effective against the targeted disease.
