Some examples include:. Eligibility in clinical trials depends on various factors and differs from study to study. Each clinical trial must establish precise inclusion and exclusion criteria defining the suitability of potential participants. The most common factors that are considered when the recruitment process begins are:. Clinical trials are not the same as medical care or complementary procedures to improve your looks.
Trials are research-based, with the goal of making breakthroughs in medicine that you may or may not benefit from. While testing on willing human subjects is crucial for the process, and the researchers try to ensure the highest safety standards, the trials intend to find answers.
You will be able to access otherwise unavailable treatment options and receive the top-notch care during the participation, often for free, but the focus of the study is not medical care itself. The table below lists some of the most common risks and benefits of participating in clinical trials:.
Clinical trials come after long pre-clinical research and, in some cases, tests on animals, so researchers can foresee potential risks and negative side effects. Since trials deal with new treatments, there is always a chance that unpredictable issues may arise during tests on humans.

This is done to see how a new therapy compares to the standard of care or to try different amounts of the treatment. Participants on a Phase II clinical trial may be asked to keep logs about how they are feeling. These trials have under patients. Phase III clinical trials compare the new therapy to the current standard of care, or what is currently being used in clinics to treat the disease. In this phase, the trial evaluates side-effects and effectiveness and tries to define whether one treatment works better than the other.
In many cases people on Phase III clinical trials are chosen randomly to either be treated with the new therapy or with the standard of care most cancer clinical trials do not give people a placebo, or sugar pill.
Phase III clinical trials include more than people. The last phase of clinical trials is Phase IV. During this phase, drugs that are newly approved by the FDA are tested in hundreds or thousands of participants. This allows doctors to collect more information about the treatment over time and in a large group to watch for longer-term side-effects.
