The type of clinical trial used depends on the questions the researchers want to answer. Listed below are some of the different types:
In some clinical trials, you may receive a placebo. A placebo looks like and is taken the same way as the study treatment that is being tested, but it does not contain active ingredients.
Comparing a study in healthy volunteers with a placebo helps to determine whether the study treatment works to improve a disease or condition.
Whether you receive the study treatment or placebo, your health will be closely monitored by a team of healthcare providers. In addition, the information learned from the clinical trial may help you and others in the future.
Once a clinical trial ends, the researchers will carefully review the information they have collected. At that point, they will make a decision about whether a study treatment or procedure works and is safe. If it is proven safe and effective in a clinical trial, the study treatment or procedure may become a therapy option or even a standard of care.

People take part in clinical trials for many reasons. When you participate in a clinical trial, you help doctors and researchers learn more about a study treatment, procedure, or disease. The information they learn may also help improve health care for people in the future.
Clinical trials are designed to look at new ways to prevent, detect, and treat disease. They are necessary to learn whether a study treatment or procedure works and is safe. Without clinical trials, study treatments and procedures would not be available to patients who may need them.
You should discuss your treatment options with your doctor before deciding to take part in a clinical trial. It’s important that all your doctors know that you are taking part in clinical trial so they can be sure the protocol does not conflict with your other medicines or treatments.
Clinical trials can be sponsored or funded by a variety of organizations or individual including healthcare providers, medical institutions, foundations, voluntary groups, and pharmaceutical companies. They may also be sponsored by government health agencies.
