A trial of the IMA970A and CV8102 vaccine for liver cancer (HepaVac-101)

Please note - this trial is no longer recruiting patients. We hope to add results when they are available.

Cancer type:

Liver cancer

Status:

Closed

Phase:

Phase 1/2

This trial is for people with very early, early or intermediate liver cancer that has not spread and who have had standard treatment. 

More about this trial

The standard treatment for very early, early or intermediate stage liver cancer includes:
IMA970A is a vaccine. CV8102 and cyclophosphamide help IMA970A work better. 
 
Researchers think this vaccine might help people with liver cancer. But first they need to find out if the vaccine:
  • is safe to give
  • triggers the immune system to act against the cancer               
As a part of this trial you will have a single treatment with a chemotherapy drug called cyclophosphamide before having IMA970A and CV8102. 
 
The main aims of this trial are to find out if this combination:
  • is safe and acceptable to give
  • can trigger the immune system

Trial design

This is a phase 1/2 trial. The trial team need about 40 people to join. 
 
You have 1 treatment of cyclophosphamide 3 days before starting the trial treatment. You have this as a drip into a vein. It takes 20 to 30 minutes. 
 
The trial treatment consists of both IMA970A and CV8102. You have a total of 9 vaccinations:
  • one every 4 weeks
  • then one every 3 weeks 
You have 2 injections, IMA970A followed by CV8102. You have both as an injection into the skin (intradermal injection). You have a total of 5 to 6 injections at each visit. 
 
You have both injections in the same area next to each other. You have them on the inside of your thigh or upper arm. The doctor will circle the area where you have the injections with a waterproof pen. So they can give all the injections in the same area. 
 
After each vaccination you stay at the hospital for at least 2 hours. This is so the team can monitor you in case you have an allergic reaction. 
 
This is the first time this vaccination has been used in people. A Data Safety Monitoring Board will review the safety of the vaccine at regular times. As a result of the Board’s review, the timing of when you have the vaccine might change. 
 
Samples
Before joining the main trial, you must agree to have 2 blood samples taken. 
 
The research team will use these samples to test for the HLA-A*02 and HLA-A*24 protein. As they think the vaccine will only work if your cancer has one of these proteins. 
 
If your cancer has already been tested for the HLA proteins the team will ask your permission to get these results. 
 
You cannot take part in the trial if your cancer doesn’t have either of these proteins. If this happens your doctor will talk to about the best treatment available to you. 
 
The team also want to know if your immune system will respond to the vaccine. They will use some of these blood samples to find out. The outcome of this won’t affect you taking part in the trial. 
 
If you have surgery before or during the trial to remove your liver cancer the team will ask for a piece of the cancer tissue. They will use this to look for substances in the tissue (biomarkers Open a glossary item) that might tell them how well the vaccine is working. 
 
You don’t have to agree to having the tissue sample taken. You can still take part in the trial.

Hospital visits

You see the doctor to have some tests before taking part. These tests include:
  • a physical examination
  • blood tests
  • heart trace (ECG Open a glossary item)
  • CT scan or MRI scan
You see the doctor 3 days before starting the vaccinations. This is to have a blood sample and to have the cyclophosphamide. 
 
During treatment you see the doctor before each vaccination to see how you are and for a blood test. 
 
You have a CT scan or MRI scan about every 3 months. 
 
You see the doctor 4 to 6 weeks after finishing treatment and have:
  • a physical examination
  • blood tests
  • heart trace (ECG)
  • CT scan or MRI scan

Side effects

Your doctor and nurse will monitor you closely for any side effects when you are having treatment.
 
IMA970A hasn’t been used in people before. So we don’t know what the side effects might be. Similar vaccines have been used in people and researchers think the side effects might be similar. 
 
The most common side effect of these vaccines was a local reaction where the injection was given. These usually appeared soon after the injection and went back to normal. This included:
  • redness of the skin
  • swelling
  • itching
  • irritation
  • pain
  • increased sensitivity
  • hardening of the skin
About 2 or 3 people out of every 100 (2% to 3%) had a severe allergic reaction affecting the whole body. It usually happened within an hour of having the vaccines but might happen sometime after. 
 
When you have IMA970A you stay in the hospital for at least 2 hours. This is to monitor you for an allergic reaction. And if this happens the nurses and doctor can treat you immediately. 
 
CV8102 has been used in one clinical trial with healthy people. Side effects that were reported include:
  • itching and pain at the injection site
  • chills
  • being sick 
  • high temperature
  • headache
  • sore muscles and sore joints
  • tiredness
We have information on the side effects of cyclophosphamide
 
Your doctor or a member of the trial team will talk to you about the side effect of all the drugs before you agree to join the trial.
