What are clinical trials?
Doctors and scientists are always looking for better ways to care for children with a Wilms tumor. To make scientific advances, doctors create research studies involving volunteers, called clinical trials. Every drug that is now approved by the U.S. Food and Drug Administration (FDA) was tested in clinical trials.
There has been much progress made in treating Wilms tumor in the past 2 decades. In fact, Wilms tumor is 1 of the best examples of the impact that clinical trials have on finding the best treatment approaches to improve outcomes and reduce side effects.
Clinical trials are used for all types and stages of Wilms tumor. Many focus on new treatments to learn if a new treatment is safe, effective, and possibly better than the existing treatments. These types of studies evaluate new drugs, different combinations of existing treatments, new approaches to radiation therapy or surgery, and new methods of treatment.
Children who participate in clinical trials can be some of the first to get a treatment before it is available to the public. However, there are some risks with a clinical trial, including possible side effects and the chance that the new treatment may not work. People are encouraged to talk with their health care team about the pros and cons of joining a specific study.
Some clinical trials study new ways to relieve symptoms and side effects during treatment. Others study ways to manage the late effects that may happen a long time after treatment. Talk with your doctor about clinical trials for symptoms and side effects.
Deciding to join a clinical trial
Parents and children decide to participate in clinical trials for many reasons. For some, a clinical trial is the best treatment option available. Because standard treatments are not perfect, people are often willing to face the added uncertainty of a clinical trial in the hope of a better result. Other parents and children volunteer for clinical trials because they know that these studies are a way to contribute to the progress in treating Wilms tumors. Even if your child does not benefit directly from the clinical trial, their participation may benefit future children with a Wilms tumor.
Insurance coverage and the costs of clinical trials differ by location and by study. In some programs, some of the person's expenses from participating in the clinical trial are reimbursed. In others, they are not. It is important to talk with the research team and your insurance company first to learn if and how your child's treatment in a clinical trial will be covered. Learn more about health insurance coverage of clinical trials.
Sometimes people have concerns that, in a clinical trial, their child may receive no treatment by being given a placebo or a “sugar pill.” The use of placebos in cancer clinical trials in this way is rare overall and not done at all in childhood cancer research. Find out more about placebos in cancer clinical trials.
Patient safety and informed consent
To join a clinical trial, parents and children must participate in a process known as informed consent. During informed consent, the doctor should:
Describe all of the treatment options so the parents and children understand how the new treatment differs from the standard treatment.
List all of the risks of the new treatment, which may or may not be different from the risks of standard treatment.
Explain what will be required of each parent and child in order to participate in the clinical trial, including the number of doctor visits, tests, and the schedule of treatment.
Clinical trials also have certain rules called “eligibility criteria” that help structure the research and keep people safe. You and the research team will carefully review these criteria together.
People who participate in a clinical trial may stop participating at any time for personal or medical reasons. This may include that the new treatment is not working or there are serious side effects. Clinical trials are also closely monitored by experts who watch for any problems with each study. It is important that parents of children participating in a clinical trial talk with their child’s doctor and researchers about who will be providing treatment and care during the clinical trial, after the clinical trial ends, and/or if they choose to leave the clinical trial before it ends.
Finding a clinical trial
Research through clinical trials is ongoing for all types of cancer. For specific topics being studied for Wilms tumors, learn more in this guide's Latest Research section.
Cancer.Net offers a lot of information about cancer clinical trials in other areas of the website, including a complete section on clinical trials and places to search for clinical trials for a specific type of cancer. The Children’s Oncology Group (COG) conducts clinical trials for most types of childhood cancer, including Wilms tumors. (Please note the COG link takes you to a separate, independent website.)
In addition, you can find a free video-based educational program about cancer clinical trials in another section of this website.
