A trial of pembrolizumab in combination with other drugs for ovarian cancer (KEYNOTE-B96)
Please note - this trial is no longer recruiting patients. We hope to add results when they are available.
Cancer type:
Status:
Phase:
This trial is looking at the combination of pembrolizumab and paclitaxel with or without bevacizumab. It is for women whose cancer has come back after having chemotherapy that included a 
.
The trial is for women who have:
These cancers are similar and the treatments are the same. In this summary when we use ovarian cancer we are referring to all 3 cancers.
More about this trial
The first treatment () doctors usually treat ovarian cancer with is a platinum drug such as carboplatin. You might have this by itself or with another chemotherapy drug such as paclitaxel.
However the cancer sometimes comes back within 6 months of having the platinum drug. This is platinum resistant ovarian cancer. When this happens you might have other drugs such as paclitaxel and bevacizumab.
Paclitaxel is a chemotherapy drug. It works by stopping cancer cells from dividing into 2 new cells. This blocks the growth of the cancer.
Bevacizumab is a . It works by stopping a protein that cancer cells need to grow new blood vessels. This means the cells aren’t able to get the food and oxygen they need to grow.
Researchers think that another targeted drug called pembrolizumab might help women with platinum resistant ovarian cancer.
Pembrolizumab is an . It works by stimulating the to recognise and kill cancer cells.
To find out if pembrolizumab can help, half the people in the trial have pembrolizumab and the other half have a dummy drug ().
In this trial you have either:
- pembrolizumab and paclitaxel with or without bevacizumab
- dummy drug (placebo) and paclitaxel with or without bevacizumab
The aims of this trial are to find out:
- whether adding pembrolizumab to paclitaxel with or without bevacizumab is better than not adding it
- what the side effects are when pembrolizumab is added
- how adding pembrolizumab affects

If you are taking hormone therapy you can continue to take it until your randomisation. - You have ongoing side effects from earlier treatment. This is apart from certain ones which your doctor will know.

non melanoma skin cancer and carcinoma in situ (CIS ). You cannot take part if you had CIS of the bladder. - You have cancer spread to the brain, spinal cord, tissues surrounding the brain or any combination of these. This is unless it has been treated, is stable and you haven’t been taking
steroids within 2 weeks of starting trial treatment.
Medical conditions
You cannot join this trial if any of these apply. You:
- have radiotherapy within 2 weeks of starting the trial treatment
- have ongoing complications from surgery or have not fully recovered
- have had a
growth factor such as G-CSF or GM-CSF within the 4 weeks before randomisation - have an
immune system that isn’t working well. You are taking any medication such as steroids that damps down the immune system. This is apart from a small dose of steroids. - have an
autoimmune disease that needed systemic treatment in the past 2 years. This is apart from certain autoimmune diseases that your doctor will know about. - have or had inflammation of the lungs not caused by an infection (
pneumonitis ) or a disease affecting the lung tissue - have an active infection that needs systemic treatment. You have HIV, hepatitis B or active hepatitis C.

Trial design
This is an international phase 3 trial. The team need 616 women worldwide to take part.
It is a double blind randomised trial. There are 2 treatment groups. Neither you nor your doctor chooses which group you are in. And neither will you nor your doctor know which group you are in.
During the trial your doctor will be able to find out which treatment group you are in if it becomes necessary.
The 2 treatment groups are:
- pembrolizumab and paclitaxel with or without bevacizumab
- dummy drug (placebo) and paclitaxel with or without bevacizumab
You doctor will talk to you about whether you are to have bevacizumab or not.
During the trial your doctor might want to give you docetaxel instead of paclitaxel. Docetaxel is similar to paclitaxel and doctors use it to treat ovarian cancer. Your doctor will talk to you about this before they swap them.
You have all the treatments through a drip into a vein.
You have pembrolizumab and the dummy drug once every 6 weeks. This is a . You have a maximum of 18 cycles (2 years).
You have paclitaxel once a week. If you are having bevacizumab you have it every 2 weeks.
If you have docetaxel instead of paclitaxel you it every 3 weeks.
You continue to have treatment as long as it is helping and the side effects aren’t too bad.
You might be able to continue treatment if your cancer gets worse while having treatment. Your doctor will talk to you about this if it happens.
After completing treatment if your cancer gets worse you might be able to have a further 9 cycles of pembrolizumab. This is only if you had pembrolizumab. Your doctor will talk to you about this if this is the case for you.
Quality of life
You fill in questionnaires:
- before starting treatment
- while you are having treatment
- at the end of treatment
The questions ask about:
- your general health and wellbeing
- what you are able to do
- any side effects
These are quality of life questionnaires.
Samples for research
You give blood samples and tissue samples as part of the trial. Where possible the team take these samples when you have bloods or tissue taken as part of your routine care.
Researchers will use these samples to look:
- at the
genes - for substances called
biomarkers
This can help them find out:
- why treatment might work better for some people and not others
- how well treatment works
- how they affect the cancer
Hospital visits
You see the doctor before taking part to have some tests. These include:
- a
physical examination - blood tests
- urine test
- heart trace (ECG)
- CT scan or MRI scan
- bone scan, an x-ray or both
During treatment you see the doctor at regular times. This is:
- to see how you are
- for blood and urine samples
- for scans
A month after treatment you see the doctor and then every 9 weeks or 12 weeks. Your doctor will tell you which one it is.
You have a scan every 9 weeks for a year and then every 12 weeks while you are in the trial.
You stay in the trial until your cancer starts to get worse or you start another treatment.
Side effects
The trial 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.

- itching, skin rash and loss of skin colour
