A clinical trial is a research study in which people volunteer to test the safety and effectiveness of new treatments. All new drugs and medical devices have to be tested in clinical trials before they can be approved by regulatory agencies such as the U.S. Food and Drug Administration (FDA) and the European Medicines Agency (EMA) for use in people.
There are clinical trials for many types of cancer treatments, including drugs, immunotherapies, surgery, and radiation. Some trials are specific to one type of cancer, such as chordoma. Other trials may include patients with many types of cancer. Additionally, the treatment being tested might not always be experimental or new; for example, a drug that is already approved for another cancer could be studied in a clinical trial to see if it also benefits chordoma patients.
Clinical trials are conducted by doctors at major medical centers, academic institutions, and community hospitals. Sometimes doctors in private practice are involved in clinical trials in collaboration with a larger group. The doctors who conduct trials are called principal investigators (PI), and they are supported by clinical trial nurses and research coordinators who help to carry out the study. Clinical trials are usually very expensive to conduct. Financial support and sponsorship of trials can come from government programs and agencies, pharmaceutical companies, academic medical centers, non-profit or family foundations, or by the doctors conducting the trial.
Patient participation in clinical trials is completely voluntary and the rights of participants are protected by law. Every medical institution has an oversight committee whose purpose is to ensure that patients’ rights are protected. Because clinical trials are studying new treatments, there can be risks involved. The trial investigators are required by law to share detailed information with patients about the trial and the treatment being studied before they enroll, to make sure patients understand and agree to any risks involved in participating. This process is called informed consent.
Clinical trials are important treatment options for any cancer patient to consider. Because standard therapies for chordoma are very limited, a clinical trial may provide an opportunity to receive a new, experimental therapy that may be more effective than the currently available options. It is important to remember, however, that the trial therapy may also be less effective than other options. Clinical trials may also make it possible for patients to gain access to clinically available therapies at a much lower cost than paying out-of-pocket for an off-label therapy. In addition, chordoma patients who participate in clinical trials contribute to knowledge that can guide treatment for future patients and potentially help identify new ways of treating this rare cancer.
There are four phases of clinical trials, which correspond to the design and goals of the study.
Clinical trials can be beneficial for patients at any stage of disease. However, because surgery and radiation are the recommended treatments for newly diagnosed chordoma patients, clinical trials for chordoma are most often designed for patients who have a recurrence, or who have advanced disease — meaning the tumor has metastasized (spread) or can no longer be fully treated with surgery and radiation.
Deciding whether to take part in a clinical trial is an important and sometimes difficult process. If you are considering trials as an option, it is important to carefully consider the possible risks and benefits of participating with your doctors and your family.
One potential risk of participating in a clinical trial is that the treatment being studied in the trial will not be effective. You may also experience unexpected side effects or side effects that are worse than those of other available treatments. It is very important that you tell the trial team about any side effects you experience while being treated in a clinical trial. They will determine if what you are experiencing is related to the trial treatment, and also what can be done to help ease the side effects you are experiencing. Because treatments being studied in a clinical trial must still be approved by regulatory agencies, it’s critical that researchers have all the facts about both the benefits and downsides of the treatment. If the treatment being tested is causing more harm than good to participants, or participants are experiencing severe side effects, researchers are obligated to stop the trial and offer other treatment options instead.
Potential benefits of participating include the possibility that you could receive a new treatment before it is available to others. You will also be under close, regular monitoring by the doctors who are the investigators for the trial, which can be beneficial both for your general health and for your cancer treatment. In most cases, the treatment being studied in the trial is provided to the study participants at no cost. However, things that are considered standard medical care — such as checkup exams, blood draws, or MRI scans — are typically covered by insurance, so you could be responsible for co-pays and deductibles for these procedures.
Clinical trials also provide benefit to the medical and patient communities in general. By participating in a trial, you can help researchers answer important questions about what types of treatments are most effective and help improve care for future chordoma patients.
Contact your insurance provider or health system to know what they will cover. The treatments being studied in clinical trials are usually given at no cost to the patient, but there are other costs that may not be covered by the trial if they are considered part of regular cancer care. This can include lab tests, imaging, physician co-pays, or treatment for side effects. You should check with your insurance provider or health system to learn more about how these costs are paid for.
Know what is expected of you. Clinical trials require participants to visit the trial site on a regular basis for checkups and to be given the treatment itself. This schedule of visits depends on the way the trial is designed. For example, a Phase 2 or 3 trial might require a check-up and lab tests only every few weeks, at which time you also receive an infusion of an IV drug or a supply of oral medication. On the other hand, Phase 1 study might have multiple visits per week that could take up the whole day. If you are not local to the site where you would enroll in the trial, you will have to consider whether you will be able to travel to the trial site for all your visits. The costs of travel can get very high, and the frequency of the travel can also cause physical and emotional stress to both the patient and the caregiver.
If you are considering drug therapies, the Chordoma Foundation Medical Advisory Board recommends that you consult with a chordoma-experienced medical oncologist about drug therapies that may be right for you based on your individual tumor and medical situation, taking into consideration the full range of options and associated evidence, including those presented in the Chordoma Foundation’s list of drug therapy options.
If you decide that you would like to join a clinical trial, the Chordoma Foundation Medical Advisory Board (MAB) recommends that all patients with recurrent or advanced chordoma consult with their medical team — including an experienced chordoma medical oncologist. This can help you determine which trial might be the best option for you based on your medical history and current situation.
You may also try searching for a clinical trial on your own through online clinical trial databases like ClinicalTrials.gov, which lists all clinical trials registered with the National Institutes of Health in the U.S., or the World Health Organization International Clinical Trial Registry Platform (WHO ICTRP). These databases can be searched by disease type, treatment type, or location.
Most clinical trials are enrolling patients at more than one site within a country or around the world. Listings in the databases mentioned above include information about all of the locations where a trial is being conducted, along with contact information for a trial coordinator at each site. If you enroll in a trial, you must be seen for all visits required by the trial at the site where you originally enrolled. As you are searching for a trial be sure to think about whether you will be able to manage any necessary travel.
All trials have inclusion and exclusion criteria, which determine who is eligible to participate in the trial. You must meet all inclusion criteria to be eligible, but if any of the exclusion criteria are true for you, you will not be allowed to participate.
Inclusion criteria for a trial might include:
Exclusion criteria for a trial might include:
These criteria help doctors ensure they are studying the treatment in the population they expect to use it for once it is approved. They help protect the safety of trial participants by excluding patients with certain health risks. The criteria also reduce differences among participants, which allows researchers to be more certain that any effects they see are because of the treatment itself. Eligibility criteria for individual trials can be found on listings in clinical trial databases such as ClinicalTrials.gov.
If you choose to participate in a trial, you will go through a screening process to ensure that you are eligible to enroll. The doctors at the trial site will need copies of your medical records to help with this process. They will meet with you to discuss your medical history and the details of the trial. At this appointment, it will be important to:
The coordinator and doctor at the trial site will talk with you about how often you must be seen at the clinic during the trial, and what will happen at those visits. You should make sure you know the purpose of the trial, potential risks and benefits, associated costs, and your rights regarding privacy and withdrawing from the trial.
Knowing what types of side effects to look out for can help you participate in the trial more effectively and help you understand when you need to contact your doctor. Be sure to find out how to get in touch with the trial team between clinic visits, in case you have concerns or are experiencing side effects.
Write down your questions before your appointment and take notes on the answers so you do not forget anything. It can be helpful to bring a friend or family member to these consultations to help you ask questions and take notes.
Before you enroll, the trial team must review all aspects of the trial with you and document your consent to participate in the trial. This process is called informed consent, and it is a very important part of enrollment. As part of informed consent, a doctor or trial coordinator will talk with you about the purpose of the trial, how long the trial will last, the treatment being studied, risks and benefits, and any costs that are your responsibility. An essential part of informed consent is a clear description of your rights as a patient, including the right to leave the trial at any time. It is also your right to ask as many questions as you need to during this process.
All of this information will also be given to you in writing, and you will be asked to sign a document stating that the trial has been explained to you, you were given time to ask questions, you understand your rights, and you agree to participate in the trial. Informed consent is legally required for your participation in a clinical trial and is meant to protect your safety and your rights as a clinical trial participant. Your consent is non-binding, which means that even after you sign the document you can change your mind at any time and you will be allowed to withdraw your consent and leave the trial.
