A trial of ipilimumab and temozolomide for people with glioblastoma (Ipi-Glio)

Cancer type:

Brain (and spinal cord) tumours

Status:

Open

Phase:

Phase 2
This trial is for people with a type of brain tumour called glioblastoma. It is for people who have had treatment with:
  • surgery
  • then radiotherapy with temozolomide 

More about this trial

Glioblastoma is one of the most common types of brain tumours in adults. The usual treatment for people with a newly diagnosed glioblastoma is:
  • surgery to remove some or all of the tumour
  • then 6 weeks of radiotherapy with temozolomide (this is called chemoradiotherapy)
  • then temozolomide alone for up to 6 months (this is the adjuvant treatment)
But glioblastomas can come back or continue to grow despite the usual treatment. In this trial, doctors want to find out whether ipilimumab can help to stop glioblastomas from coming back.
 
Ipilimumab (also called by its brand name Yervoy) is a type of targeted drug called a monoclonal antibody. It works by stimulating certain immune cells called T-cells to find and attack the cancer. Ipilimumab is already a possible treatment for people with advanced melanoma. 
 
Everyone taking part in this trial has surgery and 6 weeks of chemoradiotherapy. They then have one of the following adjuvant treatments:
  • temozolomide (the usual treatment)
  • temozolomide and ipilimumab 
The main aim of this trial is to find out whether adding ipilimumab to the usual treatment helps people with glioblastoma.

Trial design

This is a phase 2 trial. Researchers hope that around 120 people from the UK will agree to take part. 
 
Everyone has surgery to remove all or part of the tumour. And 6 weeks of radiotherapy with temozolomide (chemoradiotherapy). This is the same as the usual treatment. Your doctor can tell you more about this. 
 
You start this trial after finishing chemoradiotherapy. 
 
This is a randomised trial. The people taking part are put into 1 of the following groups at random:
  • temozolomide and ipilimumab (arm A)
  • temozolomide (arm B)
Neither you nor your doctor are able to decide which group you are in. You are 2 times more likely to have temozolomide and ipilimumab than temozolomide alone. 

Temozolomide and ipilimumab (Arm A)

You start ipilimumab within 1 week of finishing chemoradiotherapy. 
 
You have ipilimumab as a drip into your bloodstream every 3 weeks. You can have up to 4 ipilimumab treatments. It takes about one and a half hours each time you have it.  
 
You also take temozolomide tablets. You start temozolomide a month after finishing chemoradiotherapy. 
 
You have temozolomide in cycles of treatment. Each cycle lasts 28 days. You can have up to 6 cycles of treatment, taking about 6 months in total.
 
You have each cycle of temozolomide in the following way. You:
Temozolomide (Arm B)
You start temozolomide a month after finishing chemoradiotherapy. 
 
You have up to 6 treatment cycles of temozolomide. Each cycle lasts 28 days. You have each cycle in the following way. You:
  • take temozolomide tablets every day for 5 days
  • then have a break of 23 days
You then start the next cycle of treatment. 
 
Diary card
The trial team will ask you to complete a diary card. You have a new diary card for each temozolomide treatment cycle. You fill it in every day you take temozolomide and each time you take other drugs such as steroids.  
 
You return the diary card to the trial team when you finish each treatment cycle. 
 
Blood tests
You have some extra blood tests as part of this trial. You have them before the start of treatment and at set times during the trial. 

Hospital visits

You see a doctor and have some tests before taking part. These tests might include:
  • physical examination
  • blood tests 
  • urine test (for pregnancy)
During treatment, you see the trial team every 4 weeks if you join the temozolomide group (arm B). You see the trial team more regularly if you join the temozolomide and ipilimumab group (arm A).
 
You have blood tests and a physical examination each time you see the trial team. You may also have a pregnancy test if there is any possibility that you could become pregnant.
 
You have an MRI scan every 3 months during treatment. This continues for up to 6 months. 
 
When you finish treatment, you see the trial team after 6 weeks. You then see them every month.

Side effects

The trial team monitor you during treatment and afterwards. You have a phone number to call them if you are worried about anything. The team will tell you about all the possible side effects before you start the treatment. 
 
Ipilimumab affects 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. 
 
The most common side effects of ipilimumab are: 
  • loss of appetite and weight loss 
  • watery poo (diarrhoea) or constipation 
  • feeling or being sick 
  • skin rashes, itching and changes to your skin colour 
  • tiredness (fatigue
  • nerve changes that can cause tingling, numbness and weakness in fingers and toes 
  • hair loss or hair thinning 
  • pain at the site of injection 
  • low levels of thyroid hormones that can cause tiredness, weight gain and feeling cold 
  • loss of fluid in your body (dehydration) 
  • confusion, dizziness and headaches 
  • problems in your eyes such as blurred vision and pain 
  • low blood pressure and a fast heart rate 
  • sweating 
  • shortness of breath and cough 
  • bleeding and inflammation of your stomach and bowel 
  • heartburn or indigestion
  • pain in your muscles and joints 
  • flu like symptoms and high temperature (fever)
  • changes to the way your liver works
