Research and clinical trials for breast cancer
Secondary breast cancer means the cancer has spread elsewhere in the body. This is also called advanced or metastatic breast cancer.
Sadly, secondary breast cancer can’t be cured. But treatment aims to control the disease and give a good quality of life for as long as possible.
Go to Cancer Research UK’s clinical trials database if you are looking for a trial for breast cancer in the UK. You need to talk to your specialist if there are any trials that you think you might be able to take part in.
Some of the trials on this page have now stopped recruiting people. It takes time before the results are available. This is because the trial team follow the patients for a period of time and collect and analyse the results. We have included this ongoing research to give examples of the type of research being carried out in breast cancer.
When looking at the trials database, click on the ‘recruiting’, ‘closed’ and ‘results’ tabs to make sure you see all the trials.
All cancer treatments must be fully researched before they can be used for everyone. This is so we can be sure that:
they work
they work better than the treatments already available
they are safe
To make sure the research is accurate, each trial has certain entry conditions for who can take part. These are different for each trial.
Hospitals do not take part in every clinical trial. Some trials are only done in a small number of hospitals, or in one area of the country. You may need to travel quite far if you take part in these trials.
Chemotherapy is a type of anti cancer drug treatment. These drugs work by killing cancer cells. They work throughout your body and are called a systemic treatment. Researchers are looking at:
different combinations of chemotherapy drugs
combining chemotherapy with targeted drugs
combining chemotherapy with immunotherapy

Many women with secondary breast cancer take hormone therapy to try and shrink and control the cancer. Research is looking at:
new hormone drugs, such as camizestrant, giredestrant and elacestrant
combining hormone therapy with targeted drugs
Find a clinical trial into hormone therapy for breast cancer
Targeted cancer drugs work by targeting the differences in cancer cells that help them to grow and survive. Other drugs help the immune system to attack cancer. They are called immunotherapies.
Some drugs work in more than one way. So they are targeted as well as working with the immune system.
Many trials are looking at these drugs to control breast cancer that has come back or spread beyond the breast. For secondary breast cancer, researchers are looking at:
monoclonal antibodies, such as pembrolizumab or atezolizumab
cancer growth blockers, such as crizotinib, lenvatinib, or taselisib
such as niraparib
targeted cancer drugs or immunotherapy with chemotherapy
a combination of targeted cancer drugs and hormone therapy
having two different targeted cancer drugs together
new targeted cancer drugs such as inobrodib and golidoctinib
a combination of an and targeted cancer drugs
a combination of an antibody drug conjugate and immunotherapy drug
a new type of antibody drug conjugate called datopotamab deruxtecan

Triple negative breast cancers don’t have receptors for , or . So treatments such as hormone therapy or trastuzumab don’t work. Doctors are looking at ways to improve treatment.
To treat triple negative advanced breast cancer, researchers are looking at:
chemotherapy with targeted drugs such as capivasertib
a combination of targeted cancer drugs and immunotherapy
a new targeted cancer drug called HMBD-001
a combination of monoclonal antibodies

Our clinical trials aim to find out if a new treatment or procedure is safe, is better than the current treatment or helps you feel better.
Unfortunately secondary breast cancer can't be cured. The aim of treatment is to control the cancer, relieve the symptoms and maintain your quality of life. Treatments such as chemotherapy or radiotherapy can help to reduce symptoms and might make you feel better.
Secondary breast cancer means that a cancer that began in the breast has spread to another part of the body such as the bones or lungs.
You may find it difficult coping with a diagnosis of breast cancer both practically and emotionally. Find out about the things you can do and who can help you cope.
Get practical, physical and emotional support to help you cope with a diagnosis of breast cancer, and life during and after treatment.
Find out about breast cancer, including symptoms, diagnosis, treatment, survival, and how to cope with the effects on your life and relationships.
