Last year in the UK over 60,000 cancer patients enrolled on clinical trials aimed at improving cancer treatments and making them available to all.
A trial looking at combining two treatments for cancer of the liver (TACE 2)
This trial looked at the combination of sorafenib with chemoembolisation to treat cancer that started in the liver (primary liver cancer).
Cancer Research UK supported this trial.
More about this trial
There are different treatments for liver cancer. One is blocking the supply of oxygen and food that the cancer needs to grow (embolisation).
Doctors can do this by injecting small beads into the blood vessels near the cancer. The aim is to block the small blood vessels. The beads can also deliver chemotherapy directly to the cancer. This is called chemoembolisation.
Transarterial chemoembolisation (TACE) is a type of chemoembolisation used for liver cancer.
Sorafenib is a targeted cancer drug called a tyrosine kinase inhibitor. Tyrosine kinase is a chemical messenger (an enzyme) that signals cancer cells to grow. Sorafenib blocks these signals.
Sorafenib can also work by blocking the growth of new blood vessels that supply the cancer with food and oxygen.
Researchers thought that combining sorafenib with TACE might have been better than TACE alone for treating liver cancer that couldn’t be removed by surgery.
The aims of this trial were to find out:
- if combining sorafenib with TACE is better than TACE alone
- what are the side effects of combining sorafenib with TACE
- how this combination affects
quality of life
Summary of results
The trial team found that adding sorafenib to TACE wasn’t any better than TACE alone.
- 157 people had sorafenib and TACE
- 156 people had dummy drug (
placebo) and TACE
After an average follow up of just under 2 years the team looked at the average time it took before the cancer got worse. They found it was just over 7 ½ months for each group.
The team also looked at the average length of time people in each group lived. They found it was not significantly different between the two groups.
- just over 21 months for those who had sorafenib
- just over 19½ months for those who had the dummy drug
They also looked at how well the cancer was controlled in each group. This included people:
- who had no sign of cancer (complete response)
- whose cancer had shrunk (partial response)
- whose cancer had stayed the same (stable disease)
They found it was similar in both groups:
- 117 people in the sorafenib group
- 121 people in the dummy drug group
The addition of sorafenib didn’t seem to increase the side effects of TACE.
The major difference in the side effects of both groups was in the side effects well known to be caused by sorafenib. These included:
- sore mouth
- hand foot skin reaction
- skin rash
These were more common in the sorafenib group.
During the trial at a planned meeting of the
- slowing the growth of the cancer
- increasing the amount of time people lived
And it was unlikely that continuing the trial was going to show a difference.
The trial team concluded that adding sorafenib to TACE wasn’t any better than TACE only to treat liver cancer. Other treatments in combination with TACE need to be tested for this group of people. The people taking part in this trial were all from the UK.
