Clinical trials are research studies that test how well new medical approaches work in people.
Clinical trials test new ways to find, prevent, and treat. They also help doctors improve the quality of life for people with cancer by testing ways to manage the side effects of cancer and its treatment.
Today, people are living longer lives thanks to results of past clinical trials. When you take part in a clinical trial, you add to our knowledge about diseases and help improve care for people in the future.
People join clinical trials for many reasons. People living with a disease often join trials because they want to help future patients. People with certain risk factors want to help doctors learn how to prevent diseases. Healthy volunteers want to help doctors learn how to diagnose diseases early.
People with conditions and healthy volunteers join trials to play a role in research and move science forward to help others.
Clinical trials are designed to work in phases that follow strict guidelines, including who can participate. Learning how clinical trials work can help you decide if you want to join.
Every clinical trial has requirements that must be met for you to join. These requirements are called eligibility criteria.
Common eligibility criteria address things such as your:
· health
· medical history
· family medical history
· risk factors
· age
· treatment history
· tumor’s genetic changes
These criteria help reduce the medical differences among people in the trial, reduce the risk that people will be harmed, and limit people in the trial to those most likely to benefit.
When people taking part in a trial are alike in specific ways, researchers can be more certain that the results are due to the intervention or drug being tested and not to other factors.
Clinical trials to test new treatments involve a series of steps, called phases. Depending on the results of each phase, a treatment may move to testing in the next phase.
Early clinical trial phases (phases 1 and 2) test for safety, such as what the side effects are and what a safe dose is. Later phases (phase 3 and 4) compare the treatment to current standard treatments.
In a phase 1 clinical trial, researchers figure out whether a new treatment is safe, what its side effects are, whether people can tolerate it, and the highest dose that people can tolerate. These trials are done in a small group of people (around 15 to 30). They also make sure a treatment affects the condition or disease.
A phase 2 clinical trial includes more people (50 to 100) to see if the new treatment seems to work against the condition or disease. Researchers want to see how the new treatment affects the body and impacts the condition or disease. In this phase, teams continue to study safety, including short-term side effects.
In a phase 3 clinical trial, researchers compare the treatment to the current standard therapy to see which works better. They also compare the side effects of the treatments. Participants are randomly assigned to one of the treatments to ensure that any differences are real and not the result of differences in the people in each group. Phase 3 trials include large numbers of people (from 100 to several thousand) to make sure that the result is valid.
Results from phase 1–3 trials are used to make decisions about approving new treatments or existing treatments for new conditions by agencies like the US Food and Drug Administration (FDA).
A phase 4 clinical trial looks at long-term safety and effectiveness that take place after a new treatment has been approved by the FDA and is available to the public. Treatment effectiveness and safety are monitored in large, diverse populations. More information is gathered as more people use the drug or device over a longer period of time.
Learn how researchers randomly assign clinical trial participants to different treatment groups in order to prevent bias in the results.
Clinical trial randomization is the process of assigning people by chance to groups that receive different interventions or drugs in later phase trials. A computer is most often used to assign people to groups.
In the simplest trial design, the investigational group receives the study intervention or drug and the control group receives standard treatment.
At several points during and at the end of the clinical trial, researchers compare the groups to see which intervention or drug is more effective or has fewer side effects.
Randomization, in which people are assigned to groups by chance alone, helps prevent bias. Bias occurs when a trial's results are affected by human choices or other factors not related to the treatment being tested.
For example, if doctors could choose which patients to assign to which groups, some might assign healthier patients to the treatment group and sicker patients to the control group even without meaning to. This might make the treatment group appear better than the control group even if it isn’t. Randomization helps avoid biases of this type.
If you are thinking about joining a clinical trial that includes randomization, it is important to understand that neither you nor your doctor can choose which group you will be assigned to.
Placebos are another way to help prevent bias in research. The placebo is designed to look like the medicine being tested, but it is not active. Using a placebo in this way can help prevent you and your doctors from figuring out which group you are assigned to. If doctors know which group you are in, it may affect how they assess your response without meaning to.
If placebos are used it is likely because no standard treatment exists. Or they may be used in a trial that compares standard treatment plus a placebo, with standard treatment plus the study treatment. You always will be told ahead of time if a study uses a placebo.
Placebos may be used in other types of trials, such as prevention trials.
Clinical trials offer an opportunity for patients to take an active role in their health care. By participating, patients have the chance to make a difference in their own lives and those of future generations.
A clinical trial may also be the best way to get the most advanced, leading-edge treatment. Participants may have access to new drugs and treatments before they are widely available, and because controlling and recording all factors is critical to the trial's success, participants get excellent attention and are closely monitored and cared for.
