A trial of olaparib and cediranib after platinum chemotherapy for ovarian cancer that has come back (ICON9)

Cancer type:

Ovarian cancer

Status:

Open

Phase:

Phase 3

This trial is looking at long term treatment with 2 drugs called olaparib and cediranib for women whose ovarian cancer has started to grow again. It is for women whose cancer shrunk after their first course of chemotherapy Open a glossary item. And they are having a second course.

The trial is open to women who have:

  • ovarian cancer
  • fallopian tube cancer
  • primary peritoneal cancer

Doctors treat these cancers in the same way. So, when we use the term ovarian cancer in this summary, we are referring to all 3.

Cancer Research UK supports this trial.

More about this trial

Platinum chemotherapy is one of the usual treatments for ovarian cancer. This includes the drugs cisplatin and carboplatin. But sometimes the cancer can come back. You might then have a second course of chemotherapy if it worked well the first time.

Doctors are looking for ways to improve treatment in women with ovarian cancer. In this trial, they are looking at 2 drugs called cediranib and olaparib. They think that having this extra treatment after second course chemotherapy can help control the cancer.

Cediranib and olaparib are both types of targeted drugs. They work in different ways.

Olaparib is a PARP inhibitor. It blocks an enzyme Open a glossary item called PARP, which helps damaged cancer cells to repair themselves.  Doctors think that if they stop PARP working, the cancer cells will not be able to repair themselves.

Cediranib is a tyrosine kinase inhibitor. It stops cancers from being able to make new blood vessels that they need to grow. We know from research that having it with olaparib helps control the cancer for longer.

Some women in the trial have olaparib on its own. And some have olaparib and cediranib.

The main aim of the trial is to see if olaparib and cediranib can increase the length of time before the cancer starts to grow again.

You may be able join this trial if all of the following apply:

  • you have a type of ovarian cancer, fallopian tube cancer or peritoneal cancer that is high grade serous or endometroid – this means the cancer is more likely to come back

Trial design

This trial is taking place worldwide. It is a phase 3 trial. The researchers hope 618 women will take part.

Your doctor will check to see how well your second course of chemotherapy worked with a scan or blood tests. Once they have confirmed that your cancer has shrunk, and you meet all the other entry conditions, then you might be suitable to have the treatment in this trial.

It is a randomised trial. You are put into 1 of 2 groups by a computer. Neither you nor your doctor can decide which group you are in.

You have 1 of the following:

  • olaparib and cediranib (Group A)
  • olaparib (Group B)

Olaparib and cediranib are tablets.

Women in Group A take:

  • olaparib tablets twice a day
  • cediranib once a day

Women in Group B take olaparib tablets twice a day.

The trial team will tell you exactly when to start taking the tablets. You have them for as long as they are working and the side effects aren’t too bad. 

You stop treatment if your cancer starts to grow again. Your doctor will talk to you about other treatment options.

Quality of life
The trial team will ask you to fill out a questionnaire before you start treatment and at set times during treatment. The questionnaire will ask about side effects and how you’ve been feeling. This is called a quality of life study Open a glossary item.

Tissue and blood samples
The trial team will look at a sample of tissue you gave when you were first diagnosed or when you had more surgery.

You have extra blood tests as part of this trial. Where possible you have these at the same time as your routine blood tests.

They will also use the samples to:

  • look for gene changes
  • find out why these treatments work better for some people and not others
  • learn more about ovarian cancer

Hospital visits

You see a doctor and have some tests before you can join the trial. These tests include:

  • blood tests
  • urine tests
  • chest x-ray
  • physical examination
  • heart trace (ECG Open a glossary item)
  • CT scan or MRI scan

You go to hospital:

  • every 2 weeks for the first 2 months
  • then monthly for a year
  • then 2 monthly whilst you remain on treatment

At each visit you have blood tests, urine tests and a check up. You might also have to do a 24 hour urine collection. You take a container home and collect all the urine you pass in a 24 hour period. You then return the urine collection to the trial team.

You have a CT scan at:

  • 4 months
  • 8 months
  • 1 year
  • end of treatment

When you finish treatment, the trial team contact you every 3 to 6 months to see how you are getting on. They might phone you or see you at a routine hospital appointment. 

Side effects

The trial team will monitor you during the time you have treatment and you’ll have a phone number to call them if you are worried about anything.

The most common side effects of olaparib include:

The most common side effects of cediranib include:

  • tiredness
  • diarrhoea
  • high blood pressure
  • protein in the urine
  • feeling or being sick

The trial team will tell you all about the possible side effects before you join.
