A trial of RO6874281 and atezolizumab for solid cancers (BP40234 Part 3)

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

Cancer type:

Cervical cancer




Phase 2
This trial is for people with a solid cancer that has come back after treatment, got worse during treatment or has spread to another part of the body.
A solid cancer is any cancer apart from leukaemia and lymphoma. This trial is open to people who have:

More about this trial

There are 3 parts to this trial. Parts 1 and 2 are now closed. This summary is about part 3 of the trial. 
Atezolizumab is a targeted drug called an immunotherapy. It works by blocking a protein that stops the immune system from working properly. 
RO6874281 is also an immunotherapy. It works by stimulating the immune system to kill cancer cells. 
Researchers think that the combination of atezolizumab and RO6874281 might be better than giving them separately. 
Everyone in the trial will have both atezolizumab and RO6874281. 
The aims of this trial are to find out:
  • how well this combination works 
  • about the side effects of this combination

Trial design

This is a phase 2 trial. The team need 160 people to join. Everyone will have RO6874281 and atezolizumab. 
You have atezolizumab as a drip into a vein. The 1st treatment takes an hour. You are then monitored for 2 hours before having RO6874281. 
You have RO6874281 as a drip into a vein. The 1st treatment takes 2 hours. 
There are different groups in the study. How often you have treatment depends on which group you are in.  
In one group you have RO6874281 and atezolizumab on the same day every 3 weeks. Each 3 week period is a cycle of treatment.
In the other group you have RO6874281 every week and atezolizumab every other week for 4 weeks. From week 5 you have both on the same day every 2 weeks. Each 2 week period is a cycle of treatment. 
You continue to have treatment as long as your doctor thinks it is in your best interest and the side effects aren’t too bad. 
If for any reason you need to stop having RO6874281 or atezolizumab you might be able to continue having the one treatment by itself. You doctor will talk to you about this if it happens.  
The study team will take blood samples during the study. They will also take a small sample of cancer tissue (biopsy) at different times during the study.
They will use these samples to:
  • find out what happens to RO6874281 and atezolizumab in the body
  • look for substances (biomarkers) that might tell them if the treatment is working
  • measure the amount of RO6784281 and atezolizumab in your blood
  • find out if your body has developed antibodies to the treatment
  • find out more about your type of cancer

Hospital visits

You see the doctor to have some tests before starting treatment. These tests include:
  • a physical examination
  • blood tests 
  • urine test
  • heart trace (ECG)
  • breathing test (lung function tests)
  • MRI scan or CT scan
  • heart scan (ECHO or MUGA)
  • chest x-ray
You see the doctor regularly during treatment for blood tests and to see how you are. You have CT scans or MRI scans every 8 weeks.
At the end of treatment and 4 weeks later you see the doctor for:
  • a physical examination
  • blood tests 
  • urine test
  • heart trace (ECG)
  • heart scan 
You then see the doctor every 3 to 4 months for:
  • a physical examination
  • blood tests
  • urine test
You have a CT scan or MRI scan every 8 weeks for the first year and then every 12 weeks. 

Side effects

Your doctor and nurse will monitor you closely for any side effects. Let your doctor or nurse know as soon as possible if:
  • you have severe side effects 
  • your side effects aren’t getting any better
  • your side effects are getting worse
You might have a reaction when you have RO6874281 or atezolizumab. It can happen during, soon after or within 24 hours of having treatment. It usually happens when you first have them. Some of the symptoms can include:
  • a high temperature (fever), shivering or chills
  • feeling or being sick
  • high or low blood pressure
  • changes to your heart beat
  • breathing difficulties
You have medication before starting treatment to prevent a reaction. You are monitored closely during and for a while after treatment. 
Tell your nurse if you have any of the above symptoms during treatment. After treatment contact your healthcare advice line if you have any of the above. 
RO6872481 is a new drug and there might be side effects we don’t know about yet. The side effects reported so far include:
  • high temperature (fever)
  • capillary leak syndrome – if you feel faint, sick and have swollen ankles or legs contact your doctor or the health care advice line straight away
  • changes to the way the heart works
We have information about the side effects of atezolizumab
These treatments affect the immune system. This may cause inflammation in different parts of the body which can cause serious side effects. They could happen during treatment, or some months after treatment has finished. In some people, these side effects could be life threatening.
Your doctor or a member of the trial team will talk to you about the possible side effects of RO6874281 and atezolizumab before you agree to take part.
