"I was delighted to take part in a clinical trial as it has the potential to really help others in the future.”
A trial looking at using BN83495 to treat advanced womb (endometrial) cancer
Please note - this trial is no longer recruiting patients. We hope to add results when they are available.
This trial is comparing a new drug called BN83495 with megestrol acetate (megace) to treat women with advanced womb (endometrial) cancer or womb cancer that has come back (recurred). It is open to women with womb cancer that has tested positive for hormone receptors.
Doctors often use megace to treat womb cancer that has spread or come back after treatment.
BN83495 is a new drug that works by blocking sex hormones.
The researchers think that BN83495 may be better than megace to treat women with womb cancer that is advanced or has come back after treatment.
The aims of this trial are to find out
- How well BN83495 works for women with womb cancer that is advanced or has come back
- How safe BN83495 is for these women
- How it affects their quality of life

This is a phase 2 trial. It is an international trail that will recruit about 80 women from different countries around the world. It is a randomised trial. The women taking part are put into 1 of 2 groups by a computer. Neither you nor your doctor can choose which group you are in.
If you are in group 1 you will have BN83495.
If you are in group 2, you will have megestrol.
Both BN83495 and megestrol are tablets. You take a tablet every morning 30 minutes before eating breakfast.
You will have a diary to write down when you took your tablet. You bring this in when you see your doctor.
You can continue with treatment as long as your doctor thinks it is helping you.
You will be asked to fill in a questionnaire before starting treatment and during treatment. This will ask about any symptoms you have and how you feel. It is called a quality of life study.
If you take part in this trial, the researchers will ask your permission to take a small piece of tissue from when you had your surgery. They will also ask permission to take some extra blood samples.
Studying these samples may help researchers learn more about cancer of the womb and how BN83495 works in the body.
If you don’t wish to give permission for these samples, you don’t have to. You can still take part in the trial.
You will see the doctor and have some tests before taking part in this trial. These tests include
You see the doctor 2, 4 and 8 weeks after starting treatment and then every 8 weeks. You will have the following tests
- A physical examination
- Blood tests
- A urine test
- A heart trace
- CT scan or MRI scan – every 8 weeks
You see the doctor 4 weeks after finishing treatment for a physical examination.
