Over the past 40 years, breast cancer treatment has greatly improved due to lessons learned through clinical trials.
Clinical trials test the safety and benefits of new treatments as well as new combinations (or new doses) of standard treatments. They can also study other parts of care including risk reduction, diagnosis and screening.
People volunteer to take part in clinical trials. Those who join help further the knowledge base that helps improve breast cancer care.
Whether a new therapy or test becomes part of standard treatment for breast cancer depends largely on clinical trial results.
For example, clinical trials showed the benefit of hormone therapies and trastuzumab (Herceptin) and these drugs are now part of standard breast cancer treatment.
Large randomized clinical trials are viewed as the best basis for making treatment guidelines.
Dedicated physicians, researchers and other health professionals, as well as hospitals, medical research centers and funders are all key to clinical trials. However, most important are the participants!

Clinical trials take place across the country (and around the world) in many types of medical centers and hospitals.
Often, trials are funded by a single agency like the National Cancer Institute (a government agency) and are done at the same time in many sites across the country. These are called cooperative group clinical trials, and allow researchers to increase the number of people in a given study.
There are 4 main phases of clinical trials for new breast cancer treatments.
A phase 1 trial studies whether a new treatment is safe to use over a range of doses. It's mainly a drug safety study.
The treatment may be given to people with different types of cancers.
A phase 2 trial studies whether a drug (or other therapy) is an effective treatment for a certain cancer, such as breast cancer. These trials may include 25-100 people.
If a treatment is found to be effective in a phase 2 trial, a phase 3 trial will study it further.
A phase 3 trial studies how well a new treatment (including surgical procedures) works compared to the standard treatment (standard of care).
It studies the best way to give the new treatment to get the most benefit and whether the new treatment is better than the current standard treatment.
A phase 3 trial may study different doses of the same drug, different drug combinations or different sequences of giving drugs (for example, which drug is best to give first).
In a phase 3 trial, people are randomized (chosen by chance) to get either the new treatment or the standard treatment. They don't get to choose which treatment they will get. This ensures the study results reflect the true benefits and risks of the new treatment.
A phase 4 trial studies the long-term side effects of treatments or answers new questions about the treatment. It's done after a new breast cancer treatment is approved by the U.S. Food and Drug Administration (FDA-approved).
Not all clinical trials fall neatly into one category. Some trials may be a combination of 2 categories, such as a phase 1/2 or phase 2/3 trial.
Phase 0 (also called early phase 1) clinical trials are different from other phases of clinical trials because they have no treatment goals and they are not part of the FDA approval process .
Phase 0 trials can give information on whether a drug does what it’s expected to do (based on cell and/or animal data) [196-197]. For example, the trial may look at whether the drug can reach the cancer and how cancer cells in people respond to the drug [196-197].
They study a very small dose of a drug in a small number of people (usually fewer than 15 people) and last less than a week [196-198]. The dose of the drug is so small there's no possible treatment benefit [197-198]. However, this also means the chance of side effects is low .
Although not common, phase 0 trials can be an important first step in human studies of a new drug treatment.
If you have breast cancer, we encourage you to join a clinical trial. Clinical trials offer the chance to try new treatments and possibly benefit from them (except for phase 0 trials).
Learning a new therapy is better than the standard treatment can also help others. As new therapies are developed, they can open doors to other drugs and procedures that may be even more effective.
Some people worry they will get a placebo instead of an effective treatment in a clinical trial. However, placebos aren’t used in metastatic breast cancer clinical trials and aren’t commonly used in non-metastatic breast cancer trials.
Most often in a breast cancer treatment clinical trial, you will get either the new treatment or the standard treatment. So, even if you don’t get the new drug (or other new therapy), your breast cancer will be treated the same as if you weren’t in the trial.
Breast cancer trials never use a placebo instead of standard treatment.
Sometimes in a non-metastatic breast cancer trial, you may get the standard treatment plus a placebo rather than the standard treatment plus the new treatment (being studied).
Your health care provider or the clinical research staff can tell you if there’s a placebo (in addition to the standard treatment) in the study.
All clinical trials have criteria for joining the study, so you may not be eligible for a trial. Or, there may not be a clinical trial currently enrolling that’s right for you.
Learn more about eligibility for clinical trials.
Where you live may be a factor in choosing to join a clinical trial.
Some clinical trials are done in one, or only a few, medical centers. Others are done in many places across the country.
There may not be a clinical trial that’s right for you in your area. So, you may have to travel if you want to join.
Learn about programs that offer transportation and lodging assistance during treatment.
The risks of a new treatment may not be fully understood, so there may be unexpected side effects.
Testing limits these risks as much as possible. However, all the side effects of a new treatment are often not known until after long-term testing and follow-up.
The cost of the new treatment or test is usually paid for by the clinical trial.
Out-of-pocket costs for most clinical trials are the same as those for standard treatment. However, there may be extra costs if the trial is in a different medical center. For example, you may have to pay more for travel or parking.
The Affordable Care Act requires insurance companies to cover non-research, standard care costs related to a clinical trial (that aren’t covered by the trial itself) plus any standard treatment given.
Before enrolling in a clinical trial, talk with your insurance provider and find out exactly which costs are covered (and which are not). This ensures you don’t have any unexpected costs, such as out-of-network fees.
Clinical trials at the Clinical Center of the National Institutes of Health (NIH) in Bethesda, MD are free of charge to those who are eligible to join and willing to get treatment there. For more information, visit the NIH clinical center website or call 1-800-4CANCER.
Learn about financial assistance.
Komen Treatment Assistance Program
Susan G. Komen® partners with CancerCare® to offer the Komen Treatment Assistance Program which bridges the gap for underserved individuals who are actively undergoing breast cancer treatment.
With this program, we aim to help those who are facing financial challenges by providing the following to low-income, underinsured or uninsured women across the country: an assessment by an oncology social worker, limited financial assistance, breast cancer education, psychosocial support and information about local resources.
Funding helps women of any age who have been diagnosed with breast cancer, at any stage of the disease. Financial assistance is granted to women who meet pre-determined eligibility criteria. To learn more about this program and other helpful resources, call the Komen Breast Care Helpline at 1-877 GO KOMEN (1-877-465-6636).
All clinical trials have eligibility criteria (guidelines for who can join the study).
For example, each trial will have a list of medical conditions people must have (or not have) to join the study.
Clinical trials aren’t just for people who are undergoing cancer treatment. There are clinical trials for people who have finished treatment and for those who have never had breast cancer.
Learn more about eligibility criteria.
Clinical trials for people who have completed breast cancer treatment study topics such as the long-term effects of treatments or the survival benefits of lifestyle behaviors (for example, diet and exercise).
Learn more about ways to get involved in breast cancer research.
Some clinical trials focus on non-treatment areas of breast cancer, such as prevention and screening. These studies often look for people who have never had breast cancer to take part in the study.
If you're newly diagnosed with breast cancer, consider joining a clinical trial before starting treatment.
For most people with early breast cancer, treatment doesn’t start right after diagnosis. So, there’s time to look for a clinical trial that fits your needs.
Once you’ve begun standard treatment for early breast cancer, it can be difficult to join a clinical trial.
If you have a breast cancer recurrence, consider joining a clinical trial before treatment for recurrence begins or when your health care provider is considering changing treatments.
If you're diagnosed with metastatic breast cancer, consider joining a clinical trial when your provider is considering changing treatments or before starting a new treatment.
Before you join a clinical trial, discuss the risks and benefits with your health care provider.
There may be a research nurse or coordinator from the clinical trial who can give you more information about the study. See below for questions to ask your provider and/or the research staff about joining a clinical trial.
Talking with friends and family may also be helpful in your decision-making process.
All clinical trials have guidelines (eligibility criteria) for who can join the study.
Criteria vary from study to study and may be based on:
Most clinical trials are designed for select groups of people, so it’s important to find a trial that fits your situation.
If you and your health care provider decide a clinical trial is a good option for you, your provider should put you in touch with a research nurse or coordinator from the trial.
This person will guide you through the enrollment process.
Informed consent is the process of reviewing the purpose, risks, benefits and options for the study. It‘s required for all clinical trials.
If you decide to join the study, you will be asked for your written permission.
The document you sign is called a consent form and you will get a copy. This form includes the study protocol as well as the potential risks and benefits of the treatment or test.
Before joining a clinical trial, a research coordinator or nurse will go over the study protocol with you. This is part of the informed consent process. You may bring a family member or friend with you.
The study protocol describes in detail:
This is usually a long document and can feel overwhelming. However, the research coordinator or nurse will answer any questions you have.
You’ll have time to review the consent form and consider your other treatment options before you have to make a decision on joining the trial. You may want to discuss your options with your family and other loved ones.
Remember, being in a clinical trial is voluntary. You can leave the trial at any time, for any reason.
Consenting and giving your written permission to join the study does not force you to stay in the study.
Before joining a clinical trial, talk with the research coordinator, nurse or physician from the study. This person can answer your questions and discuss any concerns you may have.
You may want to take a friend or family member with you to help ask questions, take notes and give you support.
You may also record the discussion so you can review it later.
It’s a good idea to bring a list of questions and concerns. The following questions may be useful for your discussion.

It may be helpful to download and print Susan G. Komen®'s Questions to Ask Your Doctor card on clinical trials and take it with you to your next doctor appointment. There’s plenty of space to write down the answers to these questions, which you can refer to later.
You can also download other Questions to Ask Your Doctor cards on many different breast cancer topics. These cards are a nice tool for people recently diagnosed with breast cancer, who may be too overwhelmed to know where to begin to gather information.
The National Cancer Institute (NCI), a government agency, funds most clinical trials on cancer.
The NCI also sponsors groups that study the same cancer topic, such as the American College of Radiology Imaging Network. These groups include hospitals, universities and physicians who work together to study cancer issues.
The Department of Defense and the Department of Veterans Affairs are other government sources of funding for clinical trials.
Pharmaceutical and biotechnology companies and nonprofit organizations also sponsor clinical trials.
