A trial looking at a new drug called AZD9833 for people with breast cancer (Serena 1)
Please note - this trial is no longer recruiting patients. We hope to add results when they are available.
Cancer type:
Status:
Phase:
- has come back in the same place after treatment (locally recurrence)
- has spread to other parts of the body (metastatic)
More about this trial
- palbociclib
- everolimus
- abemaciclib
- capivasertib
- ribociclib
These drugs are all targeted drugs called cancer growth blockers. They block signals that cancer cells use to divide and grow.
Palbociclib, everolimus, abemaciclib and ribociclib are usual treatments for some types of advanced breast cancer.
Please note: there are 14 parts to this trial. Currently, doctors are only looking for people to join the parts of the trial looking at AZD9833 and ribociclib. This is part K and L.
The main aims of this trial are to:
- find out the best dose of AZD9833 on its own and with other drugs
- learn about the side effects of AZD9833

Trial design
This is an international phase 1 trial. Researchers hope that up to 520 people worldwide will agree to take part.
There are 14 parts to this trial. The following parts are open to recruitment:
- part K
- part L
Part K
Researchers hope that around 48 people will agree to take part in part K. Everyone has AZD9833 and ribociclib. You have both treatments as tablets that you take in the morning, with or without food.
Some people will also have a type of hormone therapy called anastrazole.
Your treatment continues for as long as it is helping you and the side effects aren’t too bad.
Part L
Researchers hope that around 48 people will agree to take part in part L.
Everyone joining part L has the same treatment as part K. Researchers want to see how well this treatment combination works in a large number of people.
Tissue and blood sample
The trial team ask you for a tissue sample of your cancer. This can be from when you had a biopsy or surgery to remove the cancer (archival tumour sample).
They may also ask you to give up to 3 new tissue samples (fresh tumour biopsies). You have them:
- before the start of treatment
- during treatment
- if your cancer gets worse
You don’t have to agree to give new tissue samples if you don’t want to. You can still take part in this trial.
You also have extra blood tests as part of this trial. Where possible, you have them at the same time as your routine blood tests. Doctors want to:
- look for different substances (markers) that can help to tell how well treatment might work
- find out what happens to AZD9833 in your body
You have the extra blood tests at set times during this trial.
Hospital visits
- a physical examination
- heart trace (ECG)
- an ultrasound scan of your heart (ECHO)
- blood tests
- urine tests
- CT scan or MRI scan
- bone scan
- an eye examination
- a test of your heart called a
holter test 
During treatment, you see the trial team regularly. How often you see them depends on when you join the trial.
You have regular tests during treatment. The tests you have include blood tests, physical examinations, and heart traces.
You also have a CT scan or MRI scan every 8 weeks, for six months. You then have a CT scan or MRI scan every 3 months. This continues for as long as the treatment is helping you and the side effects aren’t too bad.
When you finish treatment, you might see the trial team after one week, 2 weeks and a month. You have blood tests, a heart trace and a physical examination. You may continue to see the trial team afterwards if you still have side effects from treatment.
Side effects
- high blood pressure and changes to the way your heart works
- a build up of fat in the cells of your liver and lungs which may cause difficulty breathing, tummy (abdominal) pain, and yellow colouring of your skin and whites of your eyes
- shaking (tremor), agitation and fits (seizures)
