A trial looking at cediranib and olaparib for women with womb cancer (COPELIA)

Please note - this trial is no longer recruiting patients. We hope to add results when they are available.

Cancer type:

Secondary cancers
Womb (uterine or endometrial) cancer




Phase 2

This trial is for women with womb cancer that has come back or spread to other parts of the body (advanced cancer). Womb cancer is also called uterine or endometrial cancer.

It is for women who have had treatment with chemotherapy that included a platinum drug in the last year.

More about this trial

Treatment for advanced womb cancer can reduce symptoms and help you feel better.

A combination of chemotherapy drugs such as paclitaxel and carboplatin (PC) is a common treatment. But after some time, the cancer may start to grow again. You usually have more treatment with paclitaxel if this happens.

Doctors are looking for ways to help women in this situation. In this trial, they are looking at cediranib and olaparib.

Cediranib is a cancer drug that stops cancer cells from growing new blood vessels.

Olaparib is a PARP inhibitor. It blocks a protein called PARP, which helps damaged cells to repair themselves. Olaparib is already a possible treatment for women with ovarian cancer.

Everyone taking part in this trial has 1 of the following:

  • paclitaxel (the standard treatment)
  • paclitaxel and cediranib
  • cediranib and olaparib

The main aim of this trial is to find out whether cediranib and paclitaxel or olaparib helps women with advanced womb cancer.

Trial design

This is a phase 2 trial. Researchers hope that around 129 women from the UK will agree to take part.

It is a randomised trial. The women taking part are put into 1 of the following treatment groups by a computer:

  • paclitaxel (group 1)
  • paclitaxel and cediranib (group 2)
  • cediranib and olaparib (group 3)

Neither you nor your doctor can choose which group you are in.

You have paclitaxel as a drip into a vein (intravenously). You have it every week, for 3 weeks. After this you have a break of a week. And then have another 3 weeks of paclitaxel. This continues for as long as it is helping you and the side effects aren’t too bad.

It takes about an hour to have paclitaxel. 

Paclitaxel and cediranib
You have paclitaxel in the same way as group 1. And you have cediranib as tablets that you swallow whole, every day.

You continue to have paclitaxel and cediranib for as long as the cancer doesn’t get worse and the side effects aren’t too bad. It can be for up to 6 months.

After 6 months, you may be able to continue to take cediranib alone.

Cediranib and olaparib
You have cediranib and olaparib as tablets that you swallow whole. You take:

  • cediranib every day
  • olaparib twice a day

This continues for as long as the cancer doesn’t get worse and the side effects aren’t too bad.

Blood tests
You have extra blood tests as part of this trial. Doctors want to find out more about how cediranib and olaparib work. You have the extra blood tests before the start of treatment and at set times during the trial.

You do not need to agree to have the extra blood tests if you don’t want to. You can still take part in this trial.

Tissue sample
Doctors will ask some women who join group 3 to give a tissue sample (biopsy) before the start of treatment. Researchers want to look at the DNA to see why some women are more likely to get womb cancer than others.

Only certain hospitals are helping with this part of the research. Your doctor can tell you more about this.

You do not have to agree to have a biopsy if you don’t want to. You can still take part in this trial. 

Hospital visits

You see a doctor and have some tests before taking part. The tests might include:

  • a physical examination
  • blood tests
  • CT scan
  • heart trace (ECG)

During treatment, you see the trial team 3 times a month if you join group 1 or group 2. You see them every 2 weeks if you join group 3. You have blood tests and a physical examination each time you see them.

You have a CT scan every 6 weeks, for 3 months. You then have a CT scan every 12 weeks.

The trial team will give you a diary to complete at home. They will ask you to keep a record of when you take your tablets. You bring the diary with you to every trial visit.

When you finish treatment, you see the trial team after a month. You then continue to see your doctor as part of your normal follow up.

Side effects

The trial team monitor you during treatment and afterwards. You have a phone number to call them if you are worried about anything. The team will tell you about all the possible side effects before you start the trial.

The most common side effects of paclitaxel are:

The most common side effects of cediranib are:

  • high blood pressure
  • diarrhoea
  • feeling or being sick

  • diarrhoea
  • tiredness (fatigue) during and after treatment and dizziness
  • feeling or being sick and indigestion
  • loss of appetite and taste changes
