“I think it’s really important that people keep signing up to these type of trials to push research forward.”
A trial comparing gemcitabine and vandetanib with gemcitabine alone in pancreatic cancer (ViP)
Please note - this trial is no longer recruiting patients. We hope to add results when they are available.
Doctors usually treat pancreatic cancer with gemcitabine if it cannot be removed with surgery.
Pancreatic cancer is very difficult to treat. Even if it has not spread anywhere else in the body, surgery to remove pancreatic cancer may not be possible. Researchers are looking for new ways of treating pancreatic cancer that cannot be removed with surgery.
In this trial they want to use a new drug vandetanib with gemcitabine.
Tyrosine kinase is a chemical messenger (an enzyme) that sends messages to cells telling them to grow and divide. Blocking the effect of tyrosine kinase may stop cancer cells from growing and spreading.
The aims of this trial are
- To find out if gemcitabine and vandetanib are better at treating pancreatic cancer than gemcitabine alone
- To find out more about the side effects
Who can enter
You may be able to enter this trial if you
- Have cancer of the pancreas that cannot be removed
- Have cancer of the pancreas that has come back after surgery
- Have cancer that can be measured on a CT scan
- Are well enough to be up and about for at least half the day (performance status 0,1 or 2)
- Have satisfactory blood test results
- Are willing to use reliable contraception during the trial and for 1 year after if there is any chance that you or your partner could become pregnant
- Are aged 18 years or more
You cannot enter this trial if you
- Have cancer that has spread to your brain
- Have had any other cancer, apart from carcinoma in situ of the cervix or non melanoma skin cancer that was successfully treated at least 5 years ago
- Have had chemotherapy for pancreatic cancer in the last 12 months
- Have had major surgery in the last 4 weeks
- Have a wound that has not healed
- Have any other illness that could interfere with the results of the trial
- Have a severe heart condition
- Have an irregular heart beat that cannot be controlled with medication
- Have an abnormal heart trace (
- Have high blood pressure that cannot be controlled with tablets
- Have diarrhoea that may affect your ability to absorb the vandetanib
- Are unable to absorb tablets for any reason
- Have had radiotherapy in the last 4 weeks
- Are taking certain drugs for example St John’s Wort, phenytoin, carbamazepine, rifampicin, rifabutin and phenobarbital
- Are pregnant or breastfeeding
This trial will recruit 140 people in the UK. This is a randomised trial. The people taking part are put into 2 treatment groups by a computer. Neither you nor your doctor will be able to decide which group you are in. You will not know which group you are in either. This is called a ‘blind’ trial.
Everybody taking part has gemcitabine through a drip into a vein once a week for 7 weeks. Then a week with no gemcitabine.
After the first 8 weeks you now have gemcitabine once a week for 3 weeks followed by a week off. Each 4 week period is called a cycle.
Each treatment takes about 30 minutes.
People in group A take placebo tablets and people in group B take vandetanib tablets every day, even during the week they are not having gemcitabine.
You have gemcitabine and vandetanib or placebo for as long as the treatment is working.
If you agree to take part in this study, the researchers will ask for a sample of tissue taken when you had surgery to remove your cancer. If there is no tissue available from your original surgery the researchers may ask if they can take another
The researchers will also ask you for some extra blood samples.
The tissue and blood samples will be used to find out more about pancreatic cancer and its treatment in the future.
If you don’t want to give tissue or blood samples for this study, you do not have to. You can still take part in the trial.
You will see the doctors and have some tests before you start treatment. The tests include
- Physical examination
- Blood tests
- Heart trace (
- CT scan
- Pregnancy test
You will have more heart traces (ECGs) recorded during the first 12 weeks of the trial.
Each time you have gemcitabine you have a blood test and you will be asked about any pain you have been having.
Every 4 weeks you have a physical examination.
You have a CT scan every 3 months until the cancer starts to grow.
You will continue on the trial until your cancer starts to grow or you no longer want to be in the trial.
7 days after you finish the trial treatment you will see the doctors. You then see them every 3 months in clinic or they can ring you at home.
The most common side effects of gemcitabine are
The most common side effects of vandatanib are
- Feeling or being sick
- Tiredness (fatigue)
- An increase in your blood pressure
- Not wanting to eat (anorexia)
- Difficulty sleeping
We have more information about gemcitabine.
