Clinical trials are closely controlled studies needed to test new drugs, technology, and treatments.
They are offered because researchers have found ways to improve current drugs, treatments, or technologies and need to be sure the treatment is safe for human use.
Although they do not promise an immediate cure, they are an important step in a long process to find new ways to treat patients.
Joining a clinical trial is voluntary and you may not benefit directly. If you are selected to receive the treatment being tested, then you may benefit from the treatment. However, if you are selected to be part of the control group, receiving the non-experimental treatment, you will still help by contributing to the study for future patients.
