A trial of radioembolisation with TheraSphere before sorafenib for liver cancer (STOP-HCC)

Cancer type:

Liver cancer

Status:

Open

Phase:

Phase 3

This trial is looking at a treatment called radioembolisation before starting a drug called sorafenib for liver cancer. It is for people who have a type of liver cancer called hepatocellular carcinoma that can’t be removed with surgery.

More about this trial

If hepatocellular carcinoma (HCC) can’t be removed with surgery, or a type of treatment called chemo embolisation, Open a glossary item doctors usually treat it with a drug called sorafenib. But researchers are looking for ways to improve treatment. In this trial they are looking at a treatment called radioembolisation.

TheraSphere is one product that is used for radioembolisation Open a glossary item. It uses millions of tiny glass radioactive Open a glossary item beads. The beads are put directly into the liver and they give off radiation Open a glossary item for a few weeks. The radiation damages the cancer cells and the cancer’s blood supply. As the beads only give off radiation to a small area, they cause little damage to the surrounding healthy tissue.

The researchers think that having radioembolisation before starting sorafenib may be better at extending life than having sorafenib alone. In this trial, half the people will have radioembolisation before they start sorafenib and the other half will only have sorafenib.

The aims of this trial are to find out

  • If having radioembolisation before starting sorafenib is better at extending life than having sorafenib alone for HCC
  • How the cancer responds to treatment
  • More about the side effects
  • How having radioembolisation before sorafenib affects quality of life

  • You have taken an experimental drug as part of a clinical trial in the last month
  • You are still having side effects from any earlier treatment
  • You have had another cancer in the last 5 years. You may be able to join if you had a cancer that was treated successfully more than 5 years ago
  • You have certain heart problems or problems with your digestive system Open a glossary item (the trial team can advise you about this)

Trial design

This is an international phase 3 trial. The trial team need 520 people to join.

It is a randomised trial. The people taking part will be put into 1 of 2 treatment groups by a computer. Neither you nor your doctor can decide which group you are in.

• People in one group have sorafenib only
• People in the other group have sorafenib and radioembolisation Open a glossary item

People in both groups take 2 sorafenib tablets twice a day. As long as you don’t have bad side effects, you can carry on having this treatment for as long as it helps you.

If you are the group having radioembolisation, you start by having one or two treatments. The doctor makes a small cut in your groin and passes a fine tube (a catheter) from there up into blood vessels in your liver. The doctor then injects the tiny glass beads through the catheter and they get stuck in the small blood vessels in and around the cancer. You may have more radioembolisation treatment if your cancer continues to grow or new areas of cancer form.

Before you have radioembolisation, you will have a test to look at the blood supply inside your liver (angiography). This is to reduce the risk of the glass beads affecting any other areas of your body. The doctor will inject a dye that shows up the blood vessels on a digital X-ray. Very rarely, people cannot have radioembolisation because they have too much blood flowing from the liver to the lungs, stomach and intestines.

Everybody taking part will be asked to fill out a questionnaire before starting treatment, every 2 months during treatment and after finishing treatment. The questionnaire will ask about any side effects you have had and about how you have been feeling. This is called a quality of life study.

Hospital visits

You see the doctor and have some tests before taking part in the trial. These include

During treatment you see the doctor every 2 months for

  • A physical examination
  • Blood tests
  • CT scan or MRI scan

When you finish treatment, you see the trial team again and have some of the tests you had when you started the trial. After that they will check how you are every 2 months at routine hospital visits.

Side effects

The most common side effects of radioembolisation include

  • Tiredness (fatigue)
  • Tummy (abdominal) pain or bleeding in your tummy
  • Feeling sick
  • High temperature (fever)
  • Changes in your liver function tests

There is a small risk that the tiny glass beads may not reach or stay in your liver. They can then affect other parts of the body such as the tummy (abdomen) or lungs. This is very rare, but if it happens, it could cause

  • Ulcers in the stomach or intestine
  • Fluid retention or scarring of the lungs

There is also a small risk of having an allergic reaction to the dye used to test the liver’s blood supply, and a small risk of long term damage to healthy parts of the liver.

The most common side effects of sorafenib include

The trial team will talk to you about all the possible side effects before you agree to take part.
