A research study (also referred to as a clinical trial) is a study in which people volunteer to test a new medical treatment. By conducting clinical trials, we learn and understand whether new medications are safe and effective. Also, currently approved medications can also undergo testing for treatment of new indications. Clinical trials are needed to develop new medications for many conditions, including: high blood pressure, arthritis, diabetes, depression, insomnia, Alzheimer’s, etc. Once a new drug is found to be safe and effective, it may be approved by the FDA for doctors to prescribe.
