Around 1 in 5 people diagnosed with cancer in the UK take part in a clinical trial.
A trial looking at IMM-101 for cancer of the pancreas that can't be removed with surgery (IMAGE 1)
We know that this is an especially worrying time for people with cancer and their family and friends. We have separate information about coronavirus and cancer. Please read that information alongside this page. We will update that information as guidance changes.
This trial looked at an immunotherapy drug called IMM-101 with gemcitabine chemotherapy for advanced pancreatic cancer.
More about this trial
When this trial was done, doctors often used gemcitabine chemotherapy to treat cancer of the pancreas that couldn’t be removed with surgery. This can help to shrink the cancer and control symptoms, hopefully improving quality of life.
Researchers in this trial looked at a drug called IMM-101, which is a type of immunotherapy. It helps stimulate the immune system to kill the cancer cells. They wanted to find out if it helped gemcitabine to work better.
Some people in this trial had IMM-101 and gemcitabine chemotherapy. Some people had gemcitabine alone.
The main aims of this trial were to find out:
- how well gemcitabine and IMM-101 works, compared with gemcitabine alone
- more about the side effects
Summary of results
This trial showed that the combination of IMM-101and gemcitabine could be a useful treatment for pancreatic cancer that has spread.
The trial recruited 110 people with advanced pancreatic cancer who had not had chemotherapy before. They were put into 1 of 2 treatments groups at random, and:
- 75 people had IMM-101 and gemcitabine
- 35 people had gemcitabine alone
The research team looked at how long people in the two groups lived for. It was slightly longer for those who’d had IMM-101 and gemcitabine, but was similar in both groups.
The team also looked at the length of time from treatment to when half the patients were still alive. This is called median survival time. The time was:
- 6.7 months for people having IMM-101 and gemcitabine
- 5.6 months for people having gemcitabine alone
They then looked at the 92 people whose cancer had already spread to another part of the body when they joined the trial. Again they looked at median survival, and they found there was a bigger difference between the two groups. The time was:
- 7 months for people having IMM-101 and gemcitabine
- 4.4 months for people having gemcitabine alone
The research team analysed how long it was before people’s cancer started to grow again, and it was:
- 4.1 months for those who had IMM-101 and gemcitabine
- 2.4 months for those who had gemcitabine alone
Nearly everyone taking part had at least 1 side effect, but some were mild and not serious. When they analysed who’d had more serious side effects, they found it was:
- 57 out of 74 people (77%) who’d had IMM-101 and gemcitabine
- 26 out of 35 people (74%) who’d had gemcitabine alone
The most common of the more serious side effects of IMM-101 and gemcitabine were a drop in blood cells, muscle weakness and loss of energy (asthenia). The most common side effects of gemcitabine were a drop in blood cells and tiredness (fatigue).
The research team concluded that the combination of IMM-101 and gemcitabine was safe to use, and that it might be a useful treatment for people with pancreatic cancer that has spread. They suggest that this combination is looked at in further trials. And that IMM-101 could be looked at in combination with other chemotherapy drugs.
