“I was keen to go on a clinical trial. I wanted to try new cancer treatments and hopefully help future generations.”
A study looking at personalised treatment for early HER2 positive breast cancer (HER2-RADiCAL)
This study is looking at a personalised treatment plan. It is for people with
It is open to people who have:
- had surgery to remove the cancer
- a low risk of their cancer coming back after surgery
More about this trial
Doctors use a combination of chemotherapy and a
They usually start this treatment before surgery. This is to see how well this works for your cancer. So after surgery they can personalise your treatment. The aim is to not give you any more treatment than you need.
One of the targeted drugs you might have if you have HER2 positive breast cancer is trastuzumab. This is a monoclonal antibody. It works by attaching to the HER2 receptor on the surface of the cancer cell. This stops the cancer from growing.
In this study researchers are looking at continuing trastuzumab after surgery for a shorter time than the standard time. It is only for people who have a low risk of their cancer coming back.
The aims of the study are to find out:
- how safe it is to give less treatment
- how acceptable this is
Who can enter
The following bullet points are a summary of the entry conditions for this study. Talk to your doctor or the study team if you are unsure about any of these. They will be able to advise you.
Who can take part
You may be able to join this study if all of the following apply.
- You have invasive breast cancer that is
- You had at least 3
cycles of chemotherapywith trastuzumab and pertuzumab before surgery.
- You had a scan before having chemotherapy that showed your cancer was 20mm or less in size. And it showed that no more than 1
lymph nodehad cancer in it. Or your cancer was between 20mm and 50mm in size and no more than 1 lymph node had cancer in it.
- Your surgery has removed all of the cancer.
- You can take part in the study within 6 weeks of having your surgery to remove the cancer.
- A sample of tissue (
biopsy) taken before any treatment is available for the study team to access.
- You must be able to continue with trastuzumab after surgery.
- You are willing to use reliable contraception during treatment and for a time after. This is if there is any chance you or your partner could become pregnant.
- You are at least 16 years old.
Who can’t take part
You cannot join this study if any of these apply.
- You have had invasive breast cancer before.
- You had an
anthracycline drugas part of your chemotherapy before surgery.
- There are signs that your cancer may have spread to another part of the body since your diagnosis.
- When you have surgery there is still some cancer left after having had your chemotherapy before.
- You plan to have more surgery to remove cancer for example surgery to remove the lymph nodes in the armpit.
- At diagnosis your cancer was stage 3 or stage 4.
sentinel lymph nodebiopsy before having chemotherapy had cancer cells in it.
- There is scarring in 4 or more lymph nodes in the armpit.
- You had more than 9 cycles of trastuzumab.
- You had chemotherapy after surgery.
- You have had another cancer in the last 5 years. This is apart from successfully treated
non melanoma skin cancerand abnormal cells on the surface of the cervix ( CIN).
- You had a heart attack, unstable chest pain (angina) or any other major
heart problemwithin the year before starting trastuzumab.
- You have in the past had inflammation of the lungs.
- You are not able to have trastuzumab.
- You are pregnant or breastfeeding.
- You have any other medical condition or mental health problem that could affect you taking part.
The trial team need 720 people to join.
You have trastuzumab for a total of 9
You can have trastuzumab as a drip into a vein or an injection under the skin. You continue having it the same way as you did before.
You can have other standard treatment. This includes radiotherapy, bisphosphonates or hormone therapy.
During the study if your cancer comes back your doctor will talk to you about your treatment options.
The team ask for a piece of the tissue sample (biopsy) from before you started chemotherapy. As well as a piece of the tissue sample from surgery after you had chemotherapy.
If your cancer comes back and you have a biopsy to confirm this the team will ask for a piece of this sample.
There are no extra hospital visits if you take part.
The study team monitor you during treatment and afterwards. Contact your advice line or tell your doctor or nurse if any side effects are bad or not getting better.
We have information about the side effects of trastuzumab.
