A trial of SCIB1 and pembrolizumab for advanced melanoma

Cancer type:

Melanoma
Secondary cancers

Status:

Open

Phase:

Phase 2

This trial is looking at adding SCIB1 to pembrolizumab for melanoma.

It is for people whose melanoma has grown into surrounding tissues or spread elsewhere in the body. This is advanced melanoma.

More about this trial

Pembrolizumab is a usual treatment for advanced melanoma. It is an immunotherapy. But it doesn’t work for some people. Doctors think this is because their immune system Open a glossary item isn’t working well enough to attack the cancer cells.

Researchers are looking for ways to improve treatment. In this trial, they are looking at a new treatment called SCIB1.

SCIB1 is a cancer vaccine. It is a liquid that contains small pieces of DNA Open a glossary item from cancer cells. We know from previous research that SCIB1 might help activate cells in the immune system. This may help the cells of the immune system to recognise and destroy melanoma cells.

The main aims of this trial are to:

  • see if SCIB1 improves treatment results
  • see if it increases the length of time that pembrolizumab works
  • learn more about side effects of combined treatment

Trial design

This is a phase 2 trial. The researchers need 25 people to take part including about 15 from the UK.

You have:

  • SCIB1
  • pembrolizumab

You have SCIB1 as follows:

  • 5 treatments within a 6 month period
  • then every 3 months

You have 2 SCIB1  injections which you have into different areas of your upper arm or the muscle in your thigh. 2 injections are 1 treatment of SCIB1. A doctor or nurse gives the injections using a special handheld device. This injects the SCIB1 and then gives a short electrical impulse that lasts less than half a second.

You have pembrolizumab every 3 weeks. You have it as a drip into a vein.

You have treatment for up to 2 years as long as it is working and the side effects aren’t too bad.

The trial team ask you to fill out a questionnaire after each injection of SCIB1. This asks about your experience of having this type of injection.

Hospital visits

You see a doctor and have some tests before you can take part. These include:

  • physical examination
  • eye examination
  • heart trace (ECG Open a glossary item)
  • urine tests
  • blood tests
  • CT scan 

You also have a test to see if you have melanoma that makes certain proteins that your immune system can recognise. The trial team test a sample of tissue (biopsy Open a glossary item) you gave when you were first diagnosed.

You see the trial team for a check up 1 month after you finish treatment. If you do not have a regular visits to your doctor, a member of the trial team will call you every 3 months for up to a year to see how you are getting on.

You have a CT scan:

  • at the start of the trial
  • 4½ months later
  • 6 months later
  • every 3 months after that

Side effects

Having SCIB1 and pembrolizumab at the same time is a new treatment. So, there may be some side effects we don’t know about yet. The trial team will monitor you during the time you have treatment and you have a phone number to call if you are worried about anything.

Only a few people have had SCIB1. The possible side effects include:

  • bruising, redness and tenderness at the site of the injection
  • tiredness (fatigue)
  • blurred vision
  • headache

When you have the injections, you will feel twitching in your muscle, which might feel painful. Your arm and leg will be sore to the touch afterwards. 

Pembrolizumab affects the immune system. This may cause inflammation in different parts of the body which can cause serious side effects. They could happen during treatment, or some months after treatment has finished. In some people, these side effects could be life threatening.

If you have any of these side effects, you should tell the doctor or nurse as soon as possible. You should tell them that you are on or have been on an immunotherapy.

The most common side effects of pembrolizumab are:

Your doctor will talk to you about the possible side effects before you agree to take part in the trial.
