Deciding to Participate

Why Participate in a Clinical Trial

Treatment for cancer or another serious disease can involve a number of unpleasant moments—needle sticks, scans, the placement of ports and tubes, and the biggies like surgery and chemotherapy. So why would a person receiving treatment volunteer to take part in research on top of everything else?

There are many reasons for participating in a clinical study, also called a clinical trial. At Fred Hutchinson Cancer Center, we understand that the decision to take part in research belongs to you, the patient. The decision you make will probably be a result of a combination of diverse reasons—some large, some small, some based on scientific evidence, some based on personal attitudes and feelings about health and disease.

Some people participate in clinical trials because there are no standard treatments available for them or because the treatment they already tried didn’t work.

Others participate for altruistic reasons, such as wanting to advance medical knowledge. Whatever your reasons, a clinical trial may be an option for you.

Pros and Cons of Clinical Trials

As with any treatment option, clinical trials have a number of pros and cons you may want to consider when deciding whether to participate.

Some reasons to participate in a clinical trial include:

Reasons to Participate

Some reasons to participate in a clinical trial include:

  • You may gain access to new interventions that are not available otherwise—and if the new intervention proves to be better than standard care, you may be among the first to benefit from it.
  • If you are in a Phase III randomized study (meaning you’re randomly assigned to a treatment group) and you don’t receive the new treatment being studied, you will receive the standard treatment for your disease.
  • You may get closer monitoring. This is a plus for many people who have fears and concerns that can be allayed by frequent checkups and conversations with doctors and nurses.
  • You may help other people who have the same condition as you by advancing scientific knowledge of the disease and its treatment.
  • By considering all of your treatment options, including clinical trials , you are taking an active role in an important decision that affects your life.

Reasons Not to Participate

Clinical trials are not right for everybody. Some reasons you may decide not to participate are:

  • In terms of effectiveness and side effects, new treatments being studied are not always better than, or even as good as, standard care.
  • You may fear the unknown and the potential loss of choice from being in a study. For example, if you are in a randomized study, you will not get to choose which arm of the study you’re in; you will be randomly assigned to an arm. If the study is blinded, you will not know which treatment (investigational or standard) you are receiving. In early clinical studies, the safety, side effects, and effectiveness of the treatment are still being ascertained.
  • You may not have the time. Being in a study may require more time—for example, because there may be more tests or scans to monitor your response—than getting standard treatment.
  • Your health insurance plan may not cover all of the costs associated with a clinical trial.

Finding the Right Clinical Trial

Your Fred Hutch doctor has detailed knowledge about studies that may be available for people with your type and stage of cancer or other illness, and he or she is uniquely qualified to assess the potential of a new treatment for your condition.

If you are willing to participate in a clinical study, your doctor will help you determine if there are studies you may be eligible for and which one, if any, is the best choice for you. For some rare kinds of cancer, there are very few clinical studies available. For other types of cancer, you may have several studies to choose from.

Use our list of questions to ask about clinical studies to gather details on each study you’re considering. If you are eligible for a large number of studies, you may want to enlist a friend or family member to help you collect and sift through the information.

Second Opinions

Ask as many questions of your treatment team as you need to feel comfortable before deciding to participate in a study. Talk with them about how much time you have to decide on a course of treatment. Depending on your disease, doctors may need to start treatment very quickly, or you may have days or weeks to make a treatment choice.

Doctors understand that you may want a second opinion before deciding, and they will not be offended if you ask about getting one. The ideal way to do this is to discuss it with your primary oncologist to ensure that any consulting doctor has timely access to your full medical information.

Researching Clinical Trials

Decisions about treatment for cancer or another serious disease, including whether or not to participate in a study, can be overwhelming. The Internet makes searching for clinical studies easy and fast.

If you are considering participating in a study and want to know more, there are many websites that can help you. But the volume of search results can be daunting, information about studies is sometimes highly technical, and some websites leave out vital details.

Cautions When Researching Studies Online

As you review clinical studies on the Internet, ask yourself these questions:

  • Does the website indicate whether the study is Phase I, Phase II, Phase III, or Phase IV? The study phase gives you an idea of how far along a treatment is in the clinical study process and which questions the researchers are trying to answer with the study.
  • Does the website disclose the risks of participating in the study? If not, ask for this information or do more digging so you can consider the risks before making a decision about whether to participate.
  • Does the website’s list of benefits of participation include financial factors like free parking or payment for taking part in the study, rather than focusing on the medical benefits to patients? While financial incentives might be nice, be sure to weigh all the risks and benefits of participating.
  • If the website asks you to provide any personal information, does the site spell out its privacy policy for protecting this information? With any website, be mindful about what you share and how it might be used.

Be cautious about information you find online, and if you have questions be sure to talk with your Fred Hutch care team. They can help you make an informed decision about whether a particular study is right for you.

Myths vs. Facts About Clinical Studies

You’ve probably heard various things about clinical trials — some true, some false — that may impact your decision about whether to participate. Here are some myths and facts to consider.

FACT: Many measures are in place to protect the safety of people who take part in studies — from careful study design to oversight by institutional review boards and periodic monitoring of study data by independent experts. Clinical study participants receive regular and careful medical attention and are closely observed for safety concerns. During the study, researchers must inform you of any new risks, benefits, or side effects they discover. By taking part in a Phase III clinical study, you have the chance to try a new treatment that is generally not available outside of a clinical study. If the treatment is better than standard therapy, as a clinical study participant you may be among the first to benefit from it. Read more about participant safety and clinical study phases.

FACT: Some clinical studies are reserved for cancer patients who have exhausted all the treatment options for their disease, but studies are open to patients in other situations too. There are clinical studies that look at methods to prevent cancer in people at high risk. Some studies focus on ways to detect and diagnose cancer. Other studies focus on preventing recurrence in patients whose cancer is in remission. And other studies focus on treatment of patients with advanced cancer or on the quality of life of cancer patients and survivors. Read more about the various types of clinical studies.

FACT: Many people don’t even consider a clinical trial because they are afraid that their health insurance company will not cover the treatment. In fact, your health insurance may pay for treatment. The majority of patients in clinical studies do receive at least some reimbursement from their health insurance, but health insurance may not pay all the costs. Most often, the study itself will pay for the study therapy and insurance companies will pay for the routine care procedures. You can ask Fred Hutch Patient Financial Services staff and your insurance company in advance for help determining which costs are likely to be covered. Read more about health insurance and clinical studies.

FACT: Placebos, which do not contain any known active ingredient, are used in research to control for the placebo effect — the expectation that an intervention will work. A placebo may not be used in a study as a comparison or control if it would mean putting people at risk by denying them effective therapy. This is particularly true for serious illnesses, such as cancer, where placebos are rarely used. A placebo may be used in a study to test drugs that might prevent cancer, but the people enrolled in such a study would not have cancer. If a placebo is used by itself in another type of cancer study, it is used because no standard treatment exists. In this case, the study would compare the effects of a new treatment with the effects of a placebo. More often studies compare a standard treatment plus a placebo with the same standard treatment plus an investigational treatment. You can find out in advance if a study you are considering might involve a placebo.

FACT: Whether you decide to participate in a clinical study or not, through Fred Hutch you will receive the same high quality of care from some of the world’s leading cancer specialists. People in clinical studies are monitored very closely, which can be reassuring. In Phase III clinical studies, participants receive either the standard treatment or an investigational treatment that researchers have reason to believe is better than the standard treatment. In a randomized study (nearly all Phase III studies) researchers cannot guarantee which treatment you will receive, and they cannot guarantee outcomes. If one treatment arm in a study is proven to be significantly more effective during the course of the study, the participants may all be moved to that arm of the study.

FACT: You may quit a clinical trial for any reason at any time. The quality of care you receive through Fred Hutch will not be affected by your decision to participate in or withdraw from a study. If you decide to withdraw, your medical team may ask to continue monitoring you for a period of time to assess any long-term effects of the treatment you received in the study.

FACT: Older patients are underrepresented in clinical studies but not because researchers don’t want to sign them up. People age 65 or older make up 54 percent of people with new cancer diagnoses but only about one-third of adult participants (people age 30 or older) in cancer clinical studies. It’s important to test interventions in a wide variety of people because they can work differently in people of different ages, races, ethnicities, and genders; older patients are welcome in many studies.
