What you need to know about clinical research if you’re immunocompromised
If you’re one of the nearly 10 million people in the United States who is immunocompromised, it means your immune system isn’t working at full strength. You can’t fight off diseases or infections such as Covid-19 as well as people with healthy immune systems. Conditions such as lupus, diabetes and asthma can weaken your immune system, as can getting treatment for cancer or having an organ transplant. And vaccines, including the Covid-19 vaccines, don’t always work as well as they do in healthy people. Any chance of infection can be scary, serious or even deadly.
In theory, new medicines and vaccines are the best way to keep vulnerable people, such as those with compromised immune systems, safe from infections. And clinical trials — scientific studies that identify and test new vaccines and treatments — are key to finding these new medicine and vaccines.
People who are immunocompromised need more protection from infections than people with healthy immune systems, but they actually have less protection. This is because, out of concern for safety, people with weakened immune systems have historically been left out of the research that helps scientists and medical professionals discover new vaccines and treatments. One study showed that more than half of clinical trials on flu and pneumococcal vaccines left immunocompromised people out, as did around 4 out of 10 of Covid-19 vaccine studies. Some studies explicitly leave out immunocompromised patients because the treatments themselves are designed for people with otherwise healthy immune systems.
When you join a clinical trial, you’ll be randomly assigned to a group that either gets the drug or vaccine being studied or does not. You won’t know which group you’re in until the study is over.
Taking part in a clinical trial may give you early access to vaccines or treatments before they’re available to the public. If it works, you’ll have gotten those benefits without having to wait.
Participating in clinical trials is also a way to contribute to scientific discovery. By being willing to be part of research on a new treatment or vaccine, you help others access drugs or vaccines that may save their lives or protect them from serious disease. Millions of people each year benefit from medical advances because a smaller group of patients were willing to take part in clinical studies. For example, Covid-19 vaccines were developed at record speed in part because of volunteers who participated in clinical trials. More than 270 million Americans have had at least one Covid-19 vaccine dose thanks to approximately 30,000 people who participated in a vaccine trial.
Globally, more than half (55%) of all clinical trials fail — or never get off the ground — because they don’t get enough participants. That means that discoveries that could help people may be delayed or may never become available.
Participating in clinical research can present risks. You could have a negative side effect that wasn’t discovered in earlier stages of research. Or, the drug or vaccine may not work for you at all.
But people who take part in these studies also have several protections. All clinical research has to be approved by an institutional review board (also known as an IRB), an oversight group at each university or research institution whose job is to make sure research is done ethically and with patient safety top-of-mind. Also, anyone who participates in a clinical trial must receive detailed information about their involvement in the study and be given an opportunity to fully read an informed consent document.
For medicines that don’t rely on triggering an immune response to work, there should be no difference in the way people with weaker immune systems respond to medications. That means that the general protections that are in place for people to participate in clinical research also protect immunocompromised people.
If you’re wondering, “Are clinical trials safe for me as an immunocompromised person?” the best thing to do is ask your healthcare provider (HCP). The research team leading the study will also give you details about the risks to you of participating.
If you’re interested in participating in clinical research, there are several ways to learn about those opportunities.
Before signing up to participate in a clinical trial, make sure you understand the risks and benefits. Your HCP can help. Here are some questions to ask:
