A trial of veliparib with paclitaxel and carboplatin for breast cancer
Coronavirus and cancer
We know it’s a worrying time for people with cancer, we have information to help. If you have symptoms of cancer contact your doctor.
Please note - this trial is no longer recruiting patients. We hope to add results when they are available.
This trial is looking at a new drug called veliparib with the chemotherapy drugs paclitaxel and carboplatin for breast cancer. The trial is for people with breast cancer that has spread into surrounding tissue (locally advanced), or to another part of their body (secondary breast cancer). To take part in the trial, your breast cancer must have a change in the
More about this trial
Doctors can treat breast cancer with chemotherapy. Paclitaxel is a chemotherapy drug that doctors use to treat secondary breast cancer. Carboplatin is another chemotherapy drug. Doctors can use the combination of paclitaxel and carboplatin to treat breast cancer.
Veliparib is a cancer drug called a PARP inhibitor. It blocks an
The cells in your cancer already have problems repairing cell damage because of the change in a BRCA gene. Doctors hope that if they can also stop PARP working, the cancer cells will not be able to repair themselves and will die.
In this trial most of the people will have veliparib with paclitaxel and carboplatin. The others will have a dummy drug (
The researchers want to find out how well veliparib works in combination with paclitaxel and carboplatin for breast cancer.

This is an international phase 3 trial. The researchers need about 270 people worldwide to join.
It is a randomised trial. The people taking part are put into 1 of 2 treatment groups by a computer. Neither you nor your doctor will be able to decide which group you are in. And neither of you will know which group you are in. This is called a double blind trial.
- People in group 1 have carboplatin, paclitaxel and veliparib
- People in group 2 have carboplatin, paclitaxel and a dummy drug (placebo)
Out of every 3 people joining the trial, 2 will have veliparib and 1 will have the dummy drug.
Veliparib and the dummy drug are capsules. You take them twice a day for a week, and then don’t take them for the next 2 weeks.
You have paclitaxel and carboplatin as a drip into a vein. You have paclitaxel once a week. You have carboplatin once every 3 weeks.
You continue your treatment as long as the side effects aren’t too bad and it is helping you.
If your doctor decides you should stop taking the carboplatin and paclitaxel, you may continue taking the veliparib, or placebo, twice a day every day.
If you agree to take part in this trial, the researchers will ask for a sample of your cancer that was removed when you had surgery or a
They will also ask for some extra blood samples to find out what happens to veliparib in the body.
The trial team will ask you to fill out a questionnaire before you start treatment, every 6 weeks during treatment and after you finish treatment. The questionnaire will ask about side effects and how you’ve been feeling. This is called a quality of life study.
You see the doctor to have some tests before taking part in this trial. These tests include
- A physical examination
- Blood tests
- Heart trace (
- Urine test
- CT scan or MRI scan
- Bone scan
- Testing for
BRCA 1or BRCA 2
During treatment you see the doctor and have a blood test every week. You have another heart trace before starting treatment. You have a CT scan or MRI scan every 9 weeks until you complete the trial.
People whose tumour gets worse during treatment and who had the dummy drug (placebo) may be able to start taking veliparib. The trial doctor will talk to you about this if this happens to you.
At the end of the trial you see the doctor for the same tests you had before you started treatment. A month after completing the trial, you see the doctor for a physical examination and blood tests. You will then go to the clinic, or the trial team will contact you, every 2 months to see how you are.
The most common side effects of veliparib are
- Feeling or being sick
- Tiredness (fatigue)
- A drop in blood cells causing an increased risk of infection, bruising or bleeding
- Diarrhoea or constipation
