Chronic Lymphocytic Leukemia Archives

Chronic lymphocytic leukemia (CLL) is a typically slow-growing cancer which begins in lymphocytes in the bone marrow and extends into the blood. It can also spread to lymph nodes and organs such as the liver and spleen.

CLL develops when too many abnormal lymphocytes grow, crowding out normal blood cells and making it difficult for the body to fight infection.

Dr. Steven Coutre:

Well, any decision about treatment is, of course, a joint decision between the physician and the patient. It’s our job to really educate each individual patient about their options and also, I think, very importantly, determine what their goals are. You don’t really follow a strict algorithm. It’s really making a decision for each individual patient.

So, of course that takes into account other medical conditions they may have, the nature of their disease, why it is that we’re treating that individual, what we’re trying to accomplish, and very importantly, what the goals of therapy are for that individual. That may be very different, for example, for somebody who’s quite young versus somebody who’s older or who might have significant medical comorbidities.

I think patients are always well served by asking questions about the treatment, side effects of treatment, of course, these days, cost comes into play, so I think we have an obligation to let patients know the differences between the therapies because often we have choices about a therapy. There isn’t any one best therapy, for example. It’s often a number of choices, and sometimes that can be very, in some ways, confusing for patients, because they wanna know, “Well, what’s the best therapy?” and as I mentioned, it’s not so much what’s the best. It’s what’s the best for that patient, and many times that’s choices of treatment.

Some are time limited, for example. Some are continuous therapies. So, there’s plusses and minuses, and again, it all goes back to what’s your goal for that individual patient, what are their preferences in terms of the treatment that they want to receive.

The drugs that I mentioned earlier are Bruton Acalabrutinib, Venetoclax, for example. These are really the first of our new really transformative drugs for CLL. Drugs, along sometimes, with our antibodies, Rituximab and Obinutuzumab, which are really replacing the use of chemotherapy in treating the disease. So, moving forward, we’re looking at combinations of these drugs. Can we drive responses deeper? That would lend itself to stopping therapy, in some case, instead of using continuous daily therapy as we currently do with drugs like Ibrutinib or Acalabrutinib.

So, that’s the major focus right now. There, of course, will be other new drugs. There’s a third drug, Zanubrutinib, which is another BTK inhibitor, so that’ll probably play a role in treating CLL. There may be differences in side effect profiles between these drugs. There isn’t any new drug that we’re looking at currently that’s far enough along to say that it’s gonna be yet another fundamentally different, revolutionary therapy for CLL. But those, of course, can come along as we learn more about the biology of the disease.

You may have heard about CAR T-Cell Therapy, where you’re using your body’s own immune system to try to target the cancer. This has been very successful and is actually approved for use in other diseases, like large cell lymphoma, for example, but it remains very much investigational in CLL. There are also other clever ways of trying to achieve the same, endpoint, that is, using your own immune system to target the cells, that are simpler than CAR T-Cell Therapy and those kinds of approaches are also in clinical trials.

So, when you’re having the discussion about treatment, it’s always good to learn about what the latest therapies may be, even if they are investigational. I think that’s how we move the field forward and, of course, the newer drugs that we have brought forward came from clinical trials that patients greatly benefitted from. So, always ask your physician about clinical trials. Another great source for that, I think, is the Leukemia Lymphoma Society. They’re very patient-focused, they’re very up to date on the latest therapies and the latest trial results. They have a very robust presence, both online, and also, generally locally. There’s local chapters. So, I would encourage you to reach out to them for information.

How to Learn More About Your CLL


Transcript:

Dr. Steven Coutre:

Well, of course, we are in the COVID era. We don’t know how long this is going to last. And so, a very common questions that comes up from our patients with CLL is what impact does this have on them and are they more susceptible, you know, the natural things that people wanna know. With CLL in general, there probably is some compromise to the immune system, but it’s really hard to measure or quantify. Certainly, individuals who’ve had a lot of chemotherapy in the past, who have advanced disease are more susceptible to infections. In contrast, someone who’s without symptoms, has a low burden of disease probably is close to being like somebody who doesn’t have CLL. So, there’s certainly a spectrum.

Really, we just try to advise following the guidelines that we are all following in terms of social distancing at present, at being aware of being around others too closely, or those who may have symptoms. So, I think, in a way, what everyone is doing now is something that is beneficial to patients with CLL, and certainly other cancers, with respect to infection risk.

Now, what about do we have any information? Is somebody with CLL more susceptible to getting COVID? What if you do get the infection? Is it going to be more severe because you have underlying CLL? And, at least in general terms, the answer seems to be no. That’s really just based on experience, anecdotal experience, certainly in areas like New York City or Italy, for example, where infectious rates have been quite high. Colleagues have commented that their patients don’t seem to be more ill simply because they have the underlying disease or because they’re on a certain treatment, for example.

There’s actually some very interesting data suggesting that perhaps the BTK inhibitors, Ibrutinib, Acalabrutinib, et cetera, might actually confer benefit, might lessen some of the consequences of the infection, and as a result, large clinical trials have started for patients without CLL. Just anyone who has a significant COVID infection who’s hospitalized, they’re testing that hypothesis. So, it’ll be very interesting to see what we learn from this. Perhaps what we’ll learn is that being on a drug like that might actually be beneficial.

It’s certainly natural to be hesitant to come into a healthcare facility because of the risk of infection, and certainly that’s gonna vary quite a bit depending on where you are. At the height of the pandemic in New York City, of course, a lot of concern on the part of patients going into a hospital clinic, for example. Whereas, at our institution, the impact has been quite low. All institutions, of course, have taken any precautions they can to limit exposure, so, I’ve often told my patients that it’s probably safer to come into our clinic and get your blood drawn or see someone if you need to than going to the grocery store, for example, in terms of exposure.

But that’s very different than saying the same thing in the middle of New York City. So, I think you have to deal with each situation as it arises, and one would hope that your physician can give you guidance. And I think, in particular, what we can do is really decide how important it is to see somebody in person or have them come in and get a lab test there. I think in many, many, many cases, that can be avoided for the time being.

And that also is an important point, that we can provide reassurance that you know, you’re used to coming in every four months or every six months and having things checked, and in many cases we can reassure that individual that it’s okay to wait. It’s not critical to get that information right now.

So, remember that what we often emphasize in evaluating someone and making decisions when to treat is three things. It’s how you feel, what your exam is like, and what your blood counts look like. So, of course, you know how you feel. If something changed, you’re having night sweats, or a lot more fatigue, is it significantly different? Of course, you typically know if anything’s changing with your exam. Are your lymph nodes getting enlarged?

Do you notice discomfort in your abdomen because of an enlarging spleen?

And so, two of the three things you can sort of self-assess, in a way, and then based on what your blood counts have been showing over time, your physician can factor that in and decide how important it is to get that test now. And as I mentioned, in many, many cases, it’s perfectly fine to delay that. So, it’s not as difficult as it might seem to you to be able to come up with a reasonable assessment about how somebody might be doing, even in the absence of seeing them and doing an exam in person.

How Can CLL Patients Take Advantage of Telemedicine?

How to Learn More About Your CLL


Transcript:

Dr. Steven Coutre:

Well, we are in a new era, at least temporarily, and, for example, we’ve switched almost exclusively to video visits. This had largely been used for patients who lived in remote areas. They didn’t have good access or ready access to healthcare providers, and so, the government reimbursed for those kinds of visits, but not for somebody who lived close by, for example.

Well, that all changed dramatically with the COVID infections, even for our patients on clinical trials. And we’ve done the grand experiment that never would have been done otherwise, of just suddenly doing all video visits, and I must say, it’s worked out quite well so far. I think patients are quite satisfied with it, by and large. It allows them to have their questions answered and continue to have appropriate monitoring if they’re on therapy, or even if they aren’t. And so, I think, when things improve, this will continue, to some extent. So, right now, I would expect that any CLL patient would have ready access to their hematologist or oncologist via video visit.

And also, I think this whole situation has promoted a lot more video conferencing, educational video conferencing. Not having to physically attend a conference in order to get information. So, I think they’ll see a lot more educational resources out there online for them.

Well, of course, with CLL, we’re also very interested in blood counts, as are our patients, and if we’re doing remote visits, or even if they live fairly close but aren’t coming in, we do try to get the lab work done, but that’s worked out quite well. We’re used to dealing with patients coming from far distances, and so, in the past, if we wanted to get a lab result in between visits, we would simply make those arrangements with their local lab. Everybody tends to have an internist, a family doctor that they see, and so they’re familiar with getting lab tests done near where they live, and in all cases, we’ve been able to accommodate that.

And now with the increasing of electronic medical record usage and interlinking of medical record systems, we can, for example, get lab tests done at a local lab and have those. Actually, those results are directly imported into the medical record. So, they’re easily accessible to us. So, I must say, it’s been a pleasant surprise to see how well this has worked.

Cancer Survivors: Managing Emotions After Cancer Treatment

Since the 1980s, doctors have tried to describe the stages cancer survivors normally go through. Most divide them into a version of the three stages described below:

Acute Survival (Living With Cancer) – Covers cancer diagnosis and any subsequent treatment. During this time, patients will undergo treatment and may be invited to participate in a clinical trial to study new cancer treatments. Sometimes services are offered to patients and their caregivers to address emotional, psychological and financial problems.

Prolonged survival (transient cancer): Post-treatment period during which the risk of recurrence is relatively high. Many patients are relieved that treatment has ended, but are concerned that they will not visit the oncologist regularly. During this stage, patients often visit the oncologist two to four times a year, depending on their circumstances.

Permanent survival (living after cancer): survival after treatment and long-term. Although two out of three survivors declare that their lives have returned to normal, a third affirms that they continue to have physical, psychosocial or economic problems. During this stage, most survivors are cared for again by their GP. Ideally, they have developed a long-term follow-up plan with the oncologist for their regular doctor to implement.

Social and Emotional Repercussions of Cancer

In addition to the physical effects of cancer, survivors experience psychological, emotional, and spiritual consequences. Many of them affect quality of life and can manifest many years after treatment. Here are some of the most common problems cancer survivors face:

Fear of Recurrence

Many survivors live in fear that the cancer will return at some point. In some cases, a major event, such as the anniversary of the diagnosis or the end of treatment with the oncologist, can trigger these feelings. Fear can be good if it encourages you to discuss your health changes with your doctor, but it can also cause unnecessary worry. Knowing your own body will help you distinguish between normal changes and more serious symptoms.

Pain

Grief is the natural result of loss. In cancer, losses refer to health, sexual desire, fertility, and physical independence. To overcome your pain, it is important to experience all of these feelings. Support groups and psychological assistance can help you deal with these problems.

Depression

It is estimated that 70% of cancer survivors experience depression at some point. Depression can be difficult to diagnose in cancer survivors, since the symptoms are very similar to the side effects of cancer treatment, such as weight loss, tiredness, insomnia, and inability to concentrate. In a 10-year follow-up study, symptoms of depression have been found to be associated with shorter survival, so seeking treatment for depression is essential.

Body Image and Self-esteem

Cancer survivors who have suffered amputations, disfigurements, and loss of organs such as the colon or bladder often have to overcome their problems to relate to themselves and to others. A negative body image and low self-esteem can affect the survivor’s ability to maintain relationships with their partner, which will have important consequences on their quality of life. Good communication is essential to maintain or regain intimacy after cancer. Consult a doctor if problems persist.

Spirituality

Many survivors feel that life takes on new meaning after cancer and renew their commitment to certain spiritual practices or organized religion. Research indicates that spirituality improves quality of life through a strong social support network.

Survivor’s Fault

Some people feel guilty about surviving cancer when others don’t. You may be wondering “Why me?” Or reevaluate your goals and ambitions in life. If you have a prolonged feeling of guilt, a psychotherapist, a member of the clergy, or a support group can help you express your feelings.

Relations

Possibly the biggest challenge cancer survivors face is how others react to their disease. Friends, coworkers, and family members may feel uncomfortable when discussing the diagnosis of cancer. They can keep silent, avoid you, or pretend that nothing has happened. Others may use humor to try to distract you and not think about your situation, instead of offering to talk about your problems. Cancer can be a long-lasting disease, so it is essential to overcome communication barriers.

Social and Work Life

Social and professional reintegration can be accompanied by many fears: concern about being exposed to a higher risk of infection, lack of enough energy to reach the end of the workday and anxiety about not being able to think clearly due to the so-called “neurological impairment by chemotherapy “or memory loss. In overcoming a life and death situation, many cancer survivors feel alienated from people who have not had the same experience and turn to other survivors for support and friendship.

You may be reluctant to reveal to your bosses and colleagues that you are receiving cancer treatment for fear of being treated differently or even losing your job and health insurance. This creates an atmosphere of uncertainty that contributes to emotional stress. Again, honest communication with your colleagues will help you overcome these feelings.

A Look at Leukemia

What is Leukemia?

As with many other cancers, leukemia is not a singular disease. There are many types of leukemia, and while it is a common childhood cancer, leukemia actually occurs more often in older adults. Leukemia is the most common cancer in people under the age of 15, but it is most likely to affect people who are 55 or older. There are more than 60,000 cases of adult leukemia diagnosed each year, and it is more common among men than women. 

Leukemia is a broad term that describes cancer of the blood or bone marrow. It starts when the DNA of developing blood cells are damaged and the bone marrow makes abnormal cells. The abnormal blood cells are the leukemia cells which grow and divide uncontrollably. Unlike healthy cells that follow a life cycle, the leukemia cells don’t die when they are supposed to so they continue to build up, eventually overcrowding the blood. They crowd out normal white blood cells, red blood cells, and platelets so those normal cells can’t grow and function. Eventually, there are more cancer cells than healthy cells in the blood. The type of leukemia is determined based on which blood cells are affected by the abnormal cells. Leukemia usually affects the white blood cells, called leukocytes, but can occur in other blood cells. There are four main types of leukemia: chronic, acute, lymphocytic, and myelogenous.

Leukemia that grows slowly is called chronic leukemia. The cancer cells form very slowly so the body can also continue to form healthy cells, but over time the cancer cells continue to grow and the leukemia worsens. 

Acute leukemia grows very quickly and gets worse really fast. It has been identified as the most rapidly progressing cancer, and it can develop and grow in a matter of days or weeks.

Lymphocytic leukemia forms in the part of the bone marrow that makes lymphocytes, which are white blood cells that are also immune cells. Chronic lymphocytic leukemia (CLL) is most common in older adults and makes up about 25 percent of adult leukemia cases. It is more common in men than women and is very rare in children. Acute lymphoblastic leukemia (ALL) also affects older adults, but children younger than five have the highest risk of developing it.

Myelogenous leukemia forms in the bone marrow cells that produce blood cells, rather than forming in the actual blood cells. Chronic myelogenous leukemia (CML) accounts for about 15 percent of all leukemia cases in the United States. CML develops mostly in adults and is very rare in children. Acute myelogenous leukemia (AML) is a rare cancer that develops quickly with symptoms of fever, difficulty breathing, and pain in the joints. It can be caused by environmental factors, and develops more often in adults than children, and more often in men than women.

There are also several less common types of leukemia. Most of these types are chronic, and each year in the United States, about 6,000 cases of these less common leukemias are diagnosed.

  • Chronic myelomonocytic leukemia (CMML) develops from myeloid cells.
  • Juvenile myelomonocytic leukemia (JMML) is typically found in very young children and is another type of myeloid leukemia.
  • Acute promyelocytic leukemia (APL) is a subtype of AML.
  • Hairy cell leukemia is slow growing, chronic, and makes too many B cells that appear hairy wen viewed under a microscope.

Leukemia Possible Risk Factors

There are several risk factors linked to leukemia. There are environmental factors and genetic reasons why some people might develop leukemia. Some of the factors can be controlled while others can not. Age, smoking history, and exposure to hazardous chemicals are all possible risk factors. Other risk factors may include exposure to chemicals or medical treatments, personal health history, and family history. Some of the possible risk factors need more study to determine a definite link to leukemia, but being aware of your potential risk is important.

If you were exposed to chemotherapy or radiation therapy for another cancer you have a higher chance of getting leukemia later in life. Also, children who took medications to suppress their immune systems, such as after an organ transplant, may develop leukemia. Exposure to chemicals such as benzene and formaldehyde, often found in cleaning products, hair dyes, and embalming fluid, may also increase your risk of developing leukemia. Smoking and exposure to workplace chemicals like gasoline, diesel and pesticides could also be a risk factor.

There are several syndromes, conditions, and genetic disorders that can also increase leukemia risk. Li-Fraumeni syndrome, a hereditary disorder, is linked to leukemia, and children with Down syndrome have a two to three percent increased risk of developing acute myeloid or acute lymphocytic leukemia. Other genetic disorders that increase leukemia risk are Fanconi anemia, and dyskeratosis congenita (DKC). The inherited immune system conditions ataxia-telangiectasia, Bloom syndrome, Schwachmai-Diamond syndrome, and Wiskott-Aldrich syndrome also increase the risk of leukemia. Risk is also increased in patients with a history of blood disorders such as myelodysplastic syndrome, myeloproliferative neoplasm, and aplastic anemia. There are also viruses, such as the human T-lymphotropic virus (HTLV-1), linked to leukemia.

Family history can also play a role in the development of leukemia. Having a sibling with leukemia is a risk factor, and having an identical twin with leukemia gives you a one in five chance of developing it yourself.

Preventing Leukemia

There are no known ways to prevent leukemia; however, being aware of risk factors and attempting to reduce them could help. Studies have linked leukemia to smoking and obesity, so quitting smoking and having a healthy body weight could help prevent leukemia. In addition, avoiding heavy exposure to dangerous chemicals might decrease your risk.

Signs and Symptoms

There are no reliable early screening methods for leukemia and, especially in chronic leukemia, the symptoms may not be very noticeable early on. Symptoms such as fatigue and fever may not be alarming at first, and could be mistakenly attributed to other causes. Acute leukemia symptoms come on faster and are typically more noticeable. All types of leukemia can have similar symptoms, but the symptoms each individual patient has can help determine the type of leukemia. Any symptoms should be checked by a doctor.

The most common symptoms of leukemia are:

  • Extreme fatigue that doesn’t respond to a good night sleep
  • Enlarged lymph nodes that are swollen and tender as a result of leukemia cells building up
  • Unexplained fever higher than 101 degrees that occurs frequently or lasts more than three weeks with no explanation
  • Night sweats that can also occur during the day, and can drench the sheets through to the mattress
  • Bruising and excess bleeding such as frequent nose bleeds caused by poor blood clotting which is also a symptom
  • Poor blood clotting is apparent when small red or purple spots, called petechiae, appear
  • Abdominal pain occurs when white blood cells accumulate in the liver or spleen
  • Bone and joint pain usually occurs in the hips or sternum where there is a lot of bone marrow that is being crowded by abnormal cells
  • Headaches and other neurological symptoms such as seizures, dizziness, visual changes, nausea, vomiting can occur due to leukemia cells in the fluid around the brain and spinal cord
  • Unintentional weight loss of five percent or more of your body weight in 12 months or less. Weight loss can sometimes be a result of having a swollen liver or spleen which can lead to loss of appetite
  • Frequent infections occur because white blood cells aren’t working properly to fight infections
  • Anemia, or iron deficiency, occurs when there is a lack of hemoglobin in the blood to transport iron in the body. Iron deficiency can cause labored breathing and pale skin. Symptoms of anemia are nausea, fever, chills, night sweats, flu-like symptoms, weight loss, bone pain, and tiredness

Complications from Leukemia

Leukemia can cause several serious complications due to the nature of the disease and treatment. Complications such as life-threatening infections can occur when white blood cells are damaged or reduced. When white blood cells aren’t fully functioning, the body can’t properly fight infections, so any infections a leukemia patient gets, such as urinary tract infections or pneumonia, can become very serious. Low platelet counts make bleeding in areas such as the brain, the lungs, and the stomach or intestines very dangerous, while high white blood cell counts can cause leukemia cells to spill over from the blood into other organs possibly causing respiratory failure, stroke, or heart attack.

There are other complications that are related to specific types of leukemia. Notably, the development of secondary cancers and blood cancers are more likely in CLL patients. Another complication of CLL is called a Richter transformation in which the cells can transform into an aggressive form of lymphoma. Kidney failure can be a treatment-related complication of AML or ALL.

Leukemia Diagnosis 

Leukemia can’t be diagnosed based solely on symptoms, but if leukemia is suspected, in a general exam, the doctor will look for an enlarged spleen or liver and take a blood sample. Further diagnostic testing may include a bone marrow test where a long needle is used to extract marrow from the center of a bone (usually the hip). The bone marrow test will help determine if the patient has leukemia and the type of leukemia.

Staging Leukemia

Staging is used to identify the size and location of cancer in the body. Typically cancers have four stages with Stage I usually indicating the cancer is in one location and is not very large. Stage IV indicates the cancer has grown large and spread far from the original location. Most leukemias aren’t usually staged because they are in the blood and therefore have already spread throughout the body. Instead, leukemia can be considered untreated, active, in remission, or recurrent. The exception is CLL, which can spread through the lymph nodes or the blood or bone marrow, so it does have three stages.

Treatment

The earlier treatment starts for leukemia, the better chance of remission. However, thanks to some exceptional advancements in leukemia treatment medications, doctors are often able to take the time they need to come up with the best treatment plan for each individual with leukemia, even in cases of acute leukemia if life-threatening complications are not present. When coming up with a treatment plan, doctors consider the patient’s age, overall health, and most importantly, the type of leukemia the patient has.

Leukemia treatment options vary for each type of cancer:

Watchful Waiting is used when treatment for slower growing leukemias, such as CLL, may not be necessary;

Chemotherapy is the primary treatment for AML, and sometimes a bone marrow transplant is needed;

Targeted therapies are medications that are tyrosine kinase inhibitors which target cancer cells, but don’t affect healthy cells. Targeted therapies have less side effects. Many CML patients have a gene mutation that responds very well to targeted therapy;

Interferon therapy is a drug that acts similar to a naturally occurring immune response which slows and then stops the leukemia cells. This therapy can cause severe side effects;

Radiation therapy is often used in ALL to kill bone marrow tissue before a transplant is done;

Surgery to remove the spleen may be necessary, depending on the type of leukemia;

Stem cell transplant is effective in treating CML and is usually more successful in younger patients. After chemotherapy or radiation or both are used to destroy the bone marrow, new stem cells are implanted into the bone marrow so noncancerous cells can grow.

Treatment for acute leukemia can take up to two years. It is usually done in phases. In the first phase the goal is to use chemotherapy for several weeks to kill the cancer cells and put the patient in remission. The second phase is designed to kill any remaining cancer cells using chemotherapy or stem cell transplant or both. The treatments and their side effects can be pretty harsh for older patients so researchers have been focusing on finding targeted therapies for acute leukemia, which have fewer side effects. Researchers are also hoping CAR T-cell therapy, which uses the patient’s own immune system to treat cancer, could be an eventual replacement for stem cell replacement therapy in older ALL patients. AML is more aggressive and often harder to treat, but several new targeted medications have been approved to treat AML. Researchers continue to look at other targeted therapy options and other drugs for AML.

In some cases of chronic leukemia, a stem cell transplant might be required, but the main treatment is oral medications that patients will probably take for the rest of their lives. Some research is investigating whether or not patients could potentially stop taking the medications at a certain point. 

CML treatments have really advanced and there are now several drugs that target the abnormal protein that causes CML. Thanks to these targeted medications CML patients now have a close to normal life expectancy and a 90 percent five-year survival rate. Clinical trials are looking at using targeted therapies to treat CLL as well and CAR T-cell therapies are also being considered for CLL treatment.

Recovery and Survival

Leukemia represents 3.5 percent of all new cancer cases in the United States, and it is the seventh leading cause of cancer death. The outlook for leukemia patients depends on which type of leukemia they have, their overall health, and their age. Leukemia is more likely to be fatal in older patients. The average age of those who die from leukemia is 75. However, the many advances in treatment options and medications, such as targeted therapies, have created a better prognosis for many. Leukemia has a 62.7 percent five-year survival rate, and some people with leukemia can now achieve complete remission.

Empowered! Podcast: Meet Andrea Conners

Today, we’re extremely proud to introduce our first-ever Empowered! podcast. Empowered! will bring you conversations around topics that are important to patients and care partners.

For our first episode, we meet Andrea Conners. Andrea is Patient Empowerment Network’s Executive Director. Andrea shares a little bit about herself, about PEN, and her inspiration in getting involved.

 


How Can You Best Support A Friend With Cancer?

What happens when someone close to you has been diagnosed with cancer?

How do you find the right words to say?

What is the best way to support them?

And how do you cope with your own emotions and feelings at the same time?

In this month’s article, I am sharing advice that comes directly from those who have personal experience of cancer – either as a patient themselves or as a friend or family member to someone with cancer.  The following tips are some of the things that friends said and did that were most helpful to cancer patients at the time of diagnosis and treatment.

Firstly, acknowledge that this can be a hard time for you too

Hearing that a friend has been diagnosed with cancer may impact you in ways that you might not be prepared for.  You may have many different emotions to cope with. You may feel angry, sad, and scared that this is happening to your friend. You may even find the news hard to take in and feel numb.   Breast cancer survivor, Nicole McClean[1] describes her feelings of numbness on hearing the news that her best friend was diagnosed with the same disease:  “I didn’t know what to feel. I didn’t know what to say. Everything I had said to other people didn’t really apply because this was MY friend. Not a stranger that I was comforting. Not even myself that I had to give a pep talk to.”

But don’t make it about you

In the shock of hearing about a friend’s diagnosis, it can be tempting to slip into a place of dwelling on your own fears and anxieties.  Nicole cautions others not to make this about themselves. “Please don’t be a friend like me. Don’t be the friend who makes the person with the diagnosis have to stop her own grieving to console you,” she says. “This is her moment. Her time to BE consoled. I don’t ever want her to feel like she needs to console me or comfort me during this time. That’s no longer her role. It is now mine.”

Just ask what’s needed

“My number one tip,” says radiation oncologist, Dr Matthew Katz (@subatomicdoc),  is “just ask what you can do to help. It can be hard to predict and may vary at different times in the cancer experience.”  Breast  surgeon, Dr Deanna Attai (@DrAttai) agrees: “Ask the patient what do you need, ask if they just want some company to sit, listen and be present.”

Above all, advises author and advocate, Nancy Stordahl (@NancysPoint) “don’t try to be a fixer and please, avoid using platitudes. Don’t tell her she’s strong, brave or courageous. Don’t add to her burden by making her feel she must live up to some gold standard of “doing cancer right”. Let her be real. Witness her pain. Listen. Just be there.”

Listen, hear and do

“The steps to being a good friend and supporter are simple”, says Nicole, “Listen and do.”  The first part is listening. “Listen to her. Or just sit with her silently. But either way, give her space where she’s comfortable sharing with you what’s in her heart without that moment becoming about you.“  

John Moore (@john_chilmark), founder of Chilmark Research, echoes this when he says: “Listen, truly listen and they will open up in time to the fear they hold within – just how scary it can be at times.”

Julia, co-founder of online breast cancer support community @BCCWW agrees. “Listen and hear,” she advises,  “if they have bad days let them, cancer isn’t fun times. Flip side: if they feel good, believe them.”

And it’s ok to not know what to say sometimes.

“Something that I think is helpful is for friends and family to remember that it’s okay if you don’t know what to say to the person with cancer,” explains Lisa Valentine (@HabitgratLisa), ·who blogs at habitualgratitude.com. “Show up, say “I don’t know what to say, but I am here for you.” Take it from there. Showing up and listening usually takes care of what can happen next.”

HER2 breast cancer patient, Tracy (@tracyintenbury) suggests offering to go to “chemo sessions if the person with cancer would otherwise be attending alone.”  Metastatic breast cancer patient, Ilene Kaminsky (@ilenealizah) appreciated those who attended medical appointments with her “especially during the first months when everything seemed to proceed at the pace of tar, and again during critical appointments/ chemo days.”

Do what needs to be done

Don’t ask her what she needs, just do something that she needs,”  recommends Nicole. “Show up, and help out.” Chair of Cardiomyopathy, CR UK patient board and NCRI rep for kidney and bladder cancer, Alison Fielding (@alisonfielding) agrees: “Make specific offers of help such as lifts, company or chores rather than waiting to be asked.”

“Anyone who said let me know if you need anything wasn’t going to get an answer,” explains Ilene “so during difficult times, one or two of my friends would do my wash, change the sheets and put the clothes away. She’d bring me smoothies while I’d be knocked out from my pre-taxol Benadryl and knew exactly what I’d like.”

Clinical Professor of Pathology, Dr David Grenache (@ClinChemDoc), cautions following through with offers of help. “From experience: when you tell them you will do what you can to help, then follow through with that when you are asked for help.  You may have to drop a high priority task but when the call for help comes. Go!” 

Victoria (@terrortoria), founder and community manager of @YBCN_UK (which supports young women with breast cancer), recalls a friend who “made home made soup for me when I told her I couldn’t bring myself to eat things. She left them on my doorstep as I couldn’t bring myself to see people either for a time. It was a 90-minute round trip for her. She’d listened to how I felt and then helped me within my limits.”

This theme of cooked meals comes up again and again. 

“Cook meals so the person with cancer has something warm and nutritious,” recommends Tracy.  Maureen Kenny (@MaureenKenny1), a patient living with secondary breast cancer, agrees, saying “you can never go wrong with a cooked meal.”

After a long day in hospital, breast cancer patient advocate, Siobhan Feeney (@BreastDense)  recalls the day she came home to find “in the porch, cooked dinner, homemade bread, marmalade and fresh eggs.” A gift she says she’ll never forget. 

Alleviating the pressure of cooking and housework is a super practical way to help a friend with cancer. Sarah Connor (@sacosw), shares a story about her neighbor who “came once a week, took away a basket of dirty clothes, brought them back washed, dried, ready to put away. She didn’t know me very well. Still makes me tingle.”

Give thoughtful gifts

From warm socks and soft blankets to body lotion and lip balm, there are many gifts you can bring a friend who is going through treatment. Beverly A. Zavaleta MD[2], author of Braving Chemo, writes:  “Each time someone sent me a gift I felt a connectedness to the giver and to the “outside world,” which was a welcome escape from the cancer world that I was living in… when I received a gift, I appreciated the time that that person took to remember me, to think of what I might need and to choose, assemble or make the gift.”

Breast cancer survivor, Karen Murray (@murraykaren) recommends practical gifts like “hand cream (skin very dry after chemo), gel for mouth ulcers (also common), some nice sweets/fruit.”

Male breast cancer survivor, Dennis Keim (@denniskeim) suggests “a jar of Aquaphor might be a nice gift. Especially if their skin is getting hammered by chemo.”

“Help the cancer patient pamper themselves,” proposes Lisa Valentine. “You know your friend or family member well enough–get them something they wouldn’t get themselves because they would think it’s extravagant–i.e. the expensive chocolate or a pedicure.” What may seem like an indulgence can also be extremely practical. “Taking me for gel nails protected my ever softening nails,” explains Ilene Kaminsky.

Although be mindful that not everyone appreciates the same things. 

“I wasn’t interested in toiletries, candles. Wine gums – they mask the taste of a nasty pre-chemo antiemetic,” says Syliva (@SylviaB_). “People often think buying flowers is naff. I adored it when people bought me flowers. A couple of people bought spectacular flowering plants.”  Breast cancer blogger, Sheri[3] received the fabulous gift of a monthly subscription to in-home flower deliveries during treatment.

Help with treatment decisions

If you have already been through cancer yourself, your friend may turn to you for treatment advice. You can guide them to helpful resources  and share your own experience, but ultimately the final decision is theirs alone. Sometimes you may not agree about treatment decisions. This can be hard for both of you. Try to accept this and support their decision. “I think not being critical with someone’s choices is very important. Support should not be in spite of circumstances,” says Ilene Kaminsky.

Offer compassion and kindness

Two-times breast cancer survivor and patient advocate Terri Coutee[4] believes the best gifts you can offer a friend is compassion and kindness. “Hold a hand if you are with a friend or loved one in person,” she advises. “You don’t even have to say anything. Perhaps your warm, human touch is enough. Tell them you have no idea how they are feeling at the moment but want to support them in any way you can. Be sensitive to the fact they may only need someone to listen, not advise.”

John Hanley (@ChemoCookery) considers “small practical actions and warm, soothing, short reassuring words are perfect.” Words like “I’m going nowhere and I’ll be here shoulder to shoulder when you need me. A little note/text/card “Here for you 24/7 anytime.”A HUG, an Embrace, a hand, eye contact.”

Sara Liyanage, author of Ticking Off Breast Cancer [5]  reminds us that “a cancer diagnosis turns your world upside down and overnight you can become scared, emotional, vulnerable and anxious. Having friends and family step up and show kindness is a lifeline which can carry you through from diagnosis to the end of treatment (and importantly, beyond).”

Treat your friend like you normally would

Researcher, Caroline Lloyd (@TheGriefGeek), cautions us not to “make it all about the cancer, they are still a person.”  Writer and metastatic breast cancer patient, Julia Barnickle (@JuliaBarnickle) agrees. “I prefer to keep conversation as normal as possible for my own sake – I don’t want cancer to take over my life.”

Stage 4 melanoma patient advocate, Kay Curtin (@kaycurtin1) suggests you talk to your friend “like you would any friend. We haven’t suddenly become aliens who require a different style of language,”  she points out.  Sherry Reynolds (@Cascadia), whose Mom is a 15-year metastatic breast cancer patient, talks about how her mother “really appreciated it when people talked to her about regular things vs always talking about her cancer or asking how she was doing. She was living with her cancer, it wasn’t who she is.”

Know when to back off

“What I didn’t want, which is equally important, was people trying to encourage me to go anywhere or do anything,” says Syliva (@SylviaB_).“ I spent a lot of time on my sofa and felt guilty saying no to people who wanted me to go out.”

Knowing when to be there for your friend, and when to give them space isn’t always easy.  but it’s an important balancing act as a good friend.  In Tips for Being A Great Cancer Friend, Steve Rubin,[6] points out that “sometimes, the overstimulation from nurses popping in, PT sessions, and all the tests/drug schedules can become so exhausting that you just want to be left alone. Other times, the loneliness kicks in and you could really use a friendly face.”

It may take time to find the right balance, so let your friend guide you.   Nicole McClean shares her experience with her friend: “I haven’t spoken to her a lot. I didn’t want to become that sort of pesky, well-intentioned friend who searched for every little thing that might show how she was feeling at any particular moment.  Because I know that her feelings would change from moment to moment and sometimes… sometimes it’s just too much to have someone repeatedly ask you… “how are you really feeling?” even when you know they mean well. At this point, I am letting her guide me into how much she needs me and where she wants me to be.”  

At the same time, Terri Coutee advises gentle persistence:  “Don’t give up if you offer help and they don’t respond. Revisit your offer to do something for them with gentle persistence. One day they may decide they need your help,”  she says.  Maureen Kenny recalls “a friend who texted me every time she was about to go shopping to see if I needed/wanted anything while she was out. I rarely did but I always really appreciated her asking.”

Make your support ongoing

Support is not just one and done.  In the shock and drama of a crisis, friends rally round, but once the shock has worn off many disappear. True friends stick around long after the initial days, weeks and months of a cancer diagnosis. Ilene asks that friends continue to“remember birthdays, cancerversaries, and remember me on holidays. A card means a lot even to just say hi.”

Final thoughts

Many studies have found that cancer survivors with strong emotional support tend to better adjust to the changes cancer brings to their lives, have a more positive outlook, and often report a better quality of life. Research has shown that people with cancer need support from friends. You can make a big difference in the life of someone with cancer. [7]

“I personally loved just knowing I was cared for, says lobular breast cancer campaigner, Claire Turner (@ClaireTTweets). “A number of friends didn’t contact me or come and see me and that hurt, so simply be there in whatever way means something,” she advises.

“The truth is basic,” says Nicole McClean, “nobody wants somebody they love to go through cancer. Especially if they’ve been through it themselves. You want people you love to be spared this type of hardship. But you can’t protect them from it. You can only help them through it. Be there for them in the ways that they need.”

Tailoring your help to what your friend needs and enjoys most is the best way to be a friend to them. As four-times cancer survivor Sarah Dow (@he4dgirl) points out “the answers will surely be as varied as we are, both in life generally, our experience of cancer, and our connection with our friend.”

Confused About Immunotherapy and Its Side Effects? You Aren’t Alone

“You don’t look like you have cancer.”

More than one patient undergoing immunotherapy to treat cancer has reported hearing statements like that. Immunotherapy is one of the recent advances in cancer treatment that belie the stereotypes about the effects of cancer treatment. 

The side effects of immunotherapy are different from those associated with chemotherapy and radiation. However, that does not mean immunotherapy does not have side effects. Patients and care partners need to be aware of these potential side effects and to be vigilant in addressing them with their oncologists because they can signal more serious complications if left untreated.

What is Immunotherapy?

Despite the increase of immunotherapy treatment options in recent years and considerable media attention paid to advancements in this field, there remains confusion about immunotherapy and its side effects. Many cancer patients are unaware of whether immunotherapy treatments are available for their specific diagnosis. Others don’t know that genetic profiling of their tumors is usually required to determine if immunotherapy is an option and not all treatment centers routinely conduct genetic profiles of tumors. A  survey by The Cancer Support Community found that the majority of patients who received immunotherapy knew little to nothing about it prior to treatment and were unfamiliar with what to expect.

Immunotherapy works by manipulating the patient’s immune system to attack cancer cells. It is perceived as gentler and more natural than chemotherapy and radiation, without the same destructive effect on the body’s healthy tissues.  This, combined with a lack of prior understanding of immunotherapy, can lead patients and care partners ill-prepared for possible side effects.

Furthermore, immunotherapy is a category of therapies, not a single type of treatment. There are a variety of immunotherapy drugs, most of which are administered via infusion.  Side effects will vary by drug, the cancer and its location, treatment dose, and the patient’s overall health.

The following are the most common types of immunotherapy.

  • Checkpoint inhibitors use drugs to block proteins in the patient’s immune system that would otherwise restrain the immune system, often referred to as taking the “brakes” off the immune system.
  • CAR-T therapy modifies the patient’s T-cells in a lab to enhance their ability to bind to cancer cells and attack and kill them.
  • Oncolytic virus therapy uses genetically modified viruses to kill cancer cells.
  • Another therapy uses cytokines (small proteins that carry messages between cells) to stimulate the immune cells to attack cancer.

Immunotherapy can be part of combination therapy. It might be combined with chemotherapy. It might be used to shrink a tumor that is then surgically removed.  Or multiple immunotherapy drugs might be used simultaneously.

What Are The Side Effects?

With immunotherapies, side effects typically occur when the immune system gets too revved up from the treatment. The most common side effects for immunotherapy treatments are fatigue, headache, and fever with flu-like symptoms. Some people also experience general inflammation often in the form of a rash. Many melanoma patients report blotchy skin discoloration, called vitiligo, during treatment. These milder side effects can usually be managed with over-the-counter remedies and adjustments to daily activities.

For checkpoint inhibitors, the fastest growing segment of immunotherapy treatments, mild side effects occur in 30% – 50% of patients. Serious side effects typically occur in less than 5% of patients. (See “Understanding Immunotherapy Side Effects” from the National Comprehensive Cancer Network and the American Society of Clinical Oncology.)

Less common side effects are blisters, joint pain, thyroid inflammation, and colitis (inflamed colon resulting in diarrhea with cramping). Some patients who receive CAR T-cell therapy develop a condition known as cytokine release syndrome, which causes fever, elevated heart rate, low blood pressure, and rash. 

In rare cases, immunotherapy has resulted in lung inflammation, hepatitis, inflammation of the pituitary, and detrimental effects on the nervous and endocrine systems. In most cases, the conditions clear up when treatment ends.  However, there have been outcomes in which immunotherapy caused diabetes or tuberculosis.

“Overall there are fewer side effects [with immunotherapy],” explained Dr. Justin Gainor, a lung and esophageal cancer specialist at Mass General during an Immunotherapy Patient Summit hosted by the Cancer Research Institute. “But the immune system can affect anything from the top of the head down to the toes. Any organ has the potential to be affected.”

As the application of immunotherapy has expanded, so has our understanding of the potential side effects. Like most medical treatments, how one person responds to immunotherapy can be different from another even when the cancer diagnosis and drug therapy are the same.

The essential thing patients and care partners need to know about side effects is they should always be reported to their oncologist or nurse oncologist.

Why Patients Should Talk to Their Provider About Immunotherapy Side Effects

Because immunotherapy has created newer therapy options, there isn’t the volume of experiences as with older treatments. The infinite number of variables that patients provide once a treatment moves beyond clinical trials and into the general patient population generate more diverse outcomes.  And, as most therapies are less than 10 years old, there hasn’t been an opportunity to study the long-term effect of these therapies. This is why oncologists advise patients and their caregivers to be extra vigilant in noting any changes experienced during and after treatment.

Many side effects are easy to treat but medical providers want patients to be forthcoming in discussing any and all side effects. This is in part to improve understanding of side effects, but also because a mild cough or a case of diarrhea might be harbingers of a more systemic issue that will grow worse if left untreated.

Patients should not be hesitant to discuss side effects because they fear they will be taken off immunotherapy.  Sometimes a pause in treatment might be necessary, but the earlier the oncologist is made aware of a side effect, the less likely that will be necessary.

In addition, patients undergoing immunotherapy should always take the name(s) of their immunotherapy drugs and the name of their oncologist when seeing medical professionals outside of their cancer treatment team. This is especially important when visiting the ER.  Because immunotherapy drugs are newer and highly targeted to certain cancers, many medical professionals remain unfamiliar with drug interactions and treating related side effects.

Immunotherapy On The Rise

Immunotherapy treatments have resulted in reports of remission in cases that would’ve been deemed hopeless just five or 10 years ago.  The Federal Drug Administration (FDA) has approved various immunotherapy treatments for melanoma, lung cancer, head and neck cancer, bladder cancer, cervical cancer, liver cancer, stomach cancer, lymphoma, breast cancer, and most recently bladder cancer.  (Here is a list of  immunotherapies by cancer type from the Cancer Research Institute.)

“It’s revolutionized how we treat our patients,” says Dr. Gainor of Mass General about immunotherapy’s impact on lung and esophageal cancer.

Advances in immunotherapy research and trials continue to generate optimism and excitement. A clinical study in Houston is looking at using immunotherapy to prevent a recurrence. Researchers in Britain recently announced a discovery that might lead to advances in immunotherapy treatments to a much broader array of cancers.

While there is excitement around the field of immunotherapy and it has resulted in unprecedented success in treating some previously hard-to-treat cancers, it remains an option for a minority of cancer diagnoses.  It works best on solid tumors with more mutations, often referred to as having a high-mutational load or microsatellite instability (MSI) high. And it is not universally successful for every patient.

With hundreds of clinical trials involving immunotherapy alone or in combination with other therapies, it is certain more treatment options are on the horizon. As more therapies are developed and more patients with a greater variety of conditions undergo immunotherapy, we will also increase our understanding of potential side effects.

Side effects should not dissuade patients and care partners from considering immunotherapy if it is available or from advocating for genetic tests to deteimine if it is an option. Many patients undergoing immunotherapy have previously undergone chemotherapy and report that the side effects are fewer and milder by comparison.  The important thing is that patients and their partners know what to expect and communicate with their treatment team.

If the next 10 years in immunotherapy research and development are anything link eth elast 10, we can expect more exciting advancements in the battle against cancer. For more perspective on what’s ahead for immunotherapy see the Cancer Research Institute’s article: Cancer Immunotherapy in 2020 and Beyond.

Understanding Clinical Trials: A Jargon Buster Guide

When it comes to cancer treatment you or a loved one may be considering participating in a clinical trial as a treatment option.  Clinical trials are designed to evaluate the safety and effectiveness of a treatment. They may involve researchers administering drugs, taking blood or tissue samples, or checking the progress of patients as they take a treatment according to a study’s protocol.

Learning about clinical trials can be a steep learning curve – not least because the process comes with a lot of new terms, acronyms and jargon.  To help you, I’ve put together this list of the most common terms you will find when you are researching clinical trial information. This is not an exhaustive list but it is a helpful starting point. At the end of this article you will see links to find more information.

Adverse Effects (AE)

Also called Adverse Events, or Adverse Drug Reaction, AEs are any harmful event experienced by a person while they are having a drug or any other treatment or intervention. In clinical trials, researchers must always report adverse events, regardless of whether or not the event is suspected to be related to or caused by the drug, treatment or intervention.

Arm

Subsection of people within a study who have a particular intervention.

Bias

Bias is an error that distorts the objectivity of a study. It can arise if a researcher doesn’t adhere to rigorous standards in designing the study, selecting the subjects, administering the treatments, analysing the data, or reporting and interpreting the study results. It can also result from circumstances beyond a researcher’s control, as when there is an uneven distribution of some characteristic between groups as a result of randomization.

Blinding

Blinding is a method of controlling for bias in a study by ensuring that those involved are unable to tell if they are in an intervention or control group so they cannot influence the results. In a single-blind study, patients do not know whether they are receiving the active drug or a placebo. In a double-blind study, neither the patients nor the persons administering the treatments know which patients are receiving the active drug. In a triple-blind study, the patients, clinicians/researchers and the persons evaluating the results do not know which treatment patients had. Whenever blinding is used, there will always be a method in which the treatment can be unblinded in the event that information is required for safety.

Comparator

When a treatment for a specific medical condition already exists, it would be unethical to do a randomized controlled trial that would require some participants to be given an ineffective substitute. In this case, new treatments are tested against the best existing treatment, (i.e. a comparator). The comparator can also be no intervention (for example, best supportive care).

Completed

A trial is considered completed when trial participants are no longer being examined or treated (i.e. no longer in follow-up); the database has been ‘locked’ and records have been archived.

Control

A group of people in a study who do not have the intervention or test being studied. Instead, they may have the standard intervention (sometimes called ‘usual care’) or a dummy intervention (placebo). The results for the control group are compared with those for a group having the intervention being tested. The aim is to check for any differences. The people in the control group should be as similar as possible to those in the intervention group, to make it as easy as possible to detect any effects due to the intervention.

Efficacy

How beneficial a treatment is under ideal conditions (for example, in a laboratory), compared with doing nothing or opting for another type of care. A drug passes efficacy trials if it is effective at the dose tested and against the illness for which it is prescribed.

Eligibility Criteria/ Inclusion and Exclusion Criteria

Eligibility criteria ensures patients enrolling in a clinical trial share similar characteristics (e.g. gender, age, medications, disease type and status) so that the results of the study are more likely due to the treatment received rather than other factors.

Follow-up

Observation over a period of time of participants enrolled in a trial to observe changes in health status.

Informed Consent

A process (by means of a written informed consent form) by which a participant voluntarily agrees to take part in a trial, having been informed of the possible benefits, risks and side effects associated with participating in the study.

Intervention

The treatment (e.g., a drug, surgical procedure, or diagnostic test) being researched. The intervention group consists of the study participants that have been randomly assigned to receive the treatment.

Investigator

A person responsible for the conduct of the clinical trial at a trial site. If a trial is conducted by a team of individuals at a trial site, the investigator is the responsible leader of the team and may be called the principal investigator (PI).

Multicentre Trial

A clinical trial conducted according to a single protocol but at more than one site, and therefore, carried out by more than one investigator.

Number needed to treat (NNT)

The average number of patients who need to receive the treatment or other intervention for one of them to get the positive outcome in the time specified.

Outcome Measures

The impact that a test, treatment, or other intervention has on a person, group or population.

Phase I, II, III and IV Studies

Once the safety of a new drug has been demonstrated in tests on animals, it goes through a multi-phase testing process to determine its safety and efficacy in treating human patients. If a drug shows success in one phase, the evaluation moves to the next phase

  • Phase 1 tests a drug on a very small number of healthy volunteers to establish overall safety, identify side effects, and determine the dose levels that are safe and tolerable for humans.
  • Phase II trials test a drug on a small number of people who have the condition the drug is designed to treat. These trials are done to establish what dose range is most effective, and to observe any safety concerns that might arise.
  • Phase III trials test a drug on a large number of people who have the condition the drug is designed to treat. Successful completion of Phase III is the point where the drug is considered ready to be marketed.
  • Phase IV trials can investigate uses of the drug for other conditions, on a broader patient base or for longer term use.

Placebo

A fake (or dummy) treatment given to patients in the control group of a clinical trial.  Placebos are indistinguishable from the actual treatment and used so that the subjects in the control group are unable to tell who is receiving the active drug or treatment. Using placebos prevents bias in judging the effects of the medical intervention being tested.

Population

A group of people with a common link, such as the same medical condition or living in the same area or sharing the same characteristics. The population for a clinical trial is all the people the test or treatment is designed to help.

Protocol

A plan or set of steps that defines how something will be done. Before carrying out a research study, for example, the research protocol sets out what question is to be answered and how information will be collected and analysed.

Randomized Controlled Trial (RCT)

A study in which a number of similar people are randomly assigned to 2 (or more) groups to test a specific drug, treatment or other intervention. One group has the intervention being tested; the other (the comparison or control group) has an alternative intervention, a placebo, or no intervention at all. Participants are assigned to different groups without taking any similarities or differences between them into account. For example, it could involve using a computer-generated random sequence. RCTs are considered the most unbiased way of assessing the outcome of an intervention because each individual has the same chance of having the intervention.

Reliability

The ability to get the same or similar result each time a study is repeated with a different population or group.

Sample

People in a study recruited from part of the study’s target population. If they are recruited in an unbiased way, the results from the sample can be generalised to the target population as a whole.

Subjects

In clinical trials, the people selected to take part are called subjects. The term applies to both those participants receiving the treatment being investigated and to those receiving a placebo or alternate treatment.

Trial Site

The location where trial-related activities are conducted.
