Please note - this trial is no longer recruiting patients. We hope to add results when they are available.
This trial is looking at adding GC4711 to stereotactic body radiotherapy for pancreatic cancer.
It is for people:
You might have chemotherapy for pancreatic cancer that hasn’t spread, or isn’t possible to remove with surgery. After chemotherapy you might have stereotactic body radiotherapy (SBRT). Doctors are looking for ways to improve how well radiotherapy works for pancreatic cancer. In this trial they are looking at adding GC4711.
GC4711 is a drug still being studied. Early research shows that it may improve how well radiotherapy works. It might also reduce damage to tissue that radiotherapy can cause.
In this trial some people have SBRT and GC4711. And some have SBRT and a dummy drug ().
The main aims of the trial are to find out:

This phase 2 trial is taking place worldwide. The team need to find 160 people to take part including 38 from the UK.
It is a randomised trial. You are put into a group by a computer. Neither you nor your doctor will be able to decide which group you are in. Nor will you know which group you are in. Your doctor can find this out if necessary.
There are 2 treatment groups. You have 1 of the following:
Before you start SBRT you must have completed at least 6 weeks of chemotherapy. This chemotherapy is part of your and isn’t part of the trial treatment.
Trial treatment
You start trial treatment about a week after you finish chemotherapy. You have some scans at the hospital first to plan the stereotactic radiotherapy. The team can tell you when you have these scans and how long you’ll be at the hospital for.
You have 5 doses of SBRT. It takes about 15-60 minutes each time. Before each dose you have one dose of GC4711 or the dummy drug. You have this as a drip into a vein. It takes about 15 minutes each time.
Treatment takes up to about 10 days in total. The team tell you which days you have treatment on. There is likely to be a day or 2 between each treatment.
You also take a proton pump inhibitor (PPI) medication during treatment. This medication works by blocking and reducing the production of stomach acid. This gives any damaged tissue from radiotherapy time to heal.
Further treatment
After you finish SBRT, your doctor and the team will decide whether surgery is possible. If so, you may have surgery to remove the cancer. You may also have additional chemotherapy after radiotherapy or surgery. Your doctor will talk to you about surgery and what this involves.
Blood samples for research
The team ask to take some extra blood samples. Where possible, you have these at the same time as your routine blood tests. They plan to use the samples to see what happens to GC4711 in the body.
Activities of daily living questionnaire
You fill out a questionnaire at set times during the trial and after finishing treatment. The questionnaire is to find out how you are getting on with your normal activities of daily living. The team can tell you more about this.
You see a doctor and have some tests before you can take part in the trial.
These include:
You might need to have an endoscopy.
You have all your treatment at the hospital.
Follow up visits
The trial team follow you up for 3 years after your last dose of radiotherapy. You see them for a check up and blood tests:
When you finish treatment you have a CT or MRI scan at 1 month. After that you have a CT scan:
You stop having these trial check ups and scans if your cancer gets worse. Your doctor will talk to you about other treatment options. The team then continue to follow you up regularly. A member of the team may call you or see you at a routine hospital appointment.
The trial team monitor you during treatment and afterwards. Contact your advice line or tell your doctor or nurse if any side effects are bad or not getting better.
About 100 healthy volunteers have had GC4711 so far. The most common side effects of GC4711 we know about so far include:
The most common side effects of stereotactic body radiotherapy include:
The doctor will talk to you about all the possible side effects of treatment when you join the trial.
