A trial of a new drug called IMCgp100 for people with a type of eye cancer called uveal melanoma

Cancer type:

Eye cancer
Melanoma
Secondary cancers

Status:

Open

Phase:

Phase 2

This trial is for people with uveal melanoma that has spread to other parts of the body (advanced uveal melanoma). It is for people who are going to have treatment for the first time. 

More about this trial

Most melanomas start in the skin, but they can also start in other parts of the body, including the eye. Melanoma that starts in the middle tissue layer of the eye (the choroid), the iris and the ciliary body is called uveal melanoma

Dacarbazine is a chemotherapy drug. It is a possible treatment for uveal melanoma. You may also have treatment with immunotherapy drugs such as:
Ipilimumab and pembrolizumab work by stimulating the immune system Open a glossary item to recognise and attack cancer cells.
 
IMCgp100 is a new type of immunotherapy. It works by stimulating certain immune system cells called T-cells to find and kill the cancer. 
 
Everyone taking part in this trial receives 1 of the following:
  • IMCgp100
  • dacarbazine, ipilimumab or pembrolizumab (standard treatment)
The main aim of this trial is to find out whether IMCgp100 is better than the standard treatment for people with advanced uveal melanoma (metastatic).

Trial design

This is a phase 2 trial. Researchers need up to 327 people to take part. 
 
It is a randomised trial. Everyone taking part is put into 1 of the following treatment groups by a computer:
  • IMCgp100
  • dacarbazine, ipilimumab or pembrolizumab (standard treatment)
Neither you nor your doctor will be able to decide which group you are in. And you are 2 times more likely to have IMCgp100 than the standard treatment. 
 
IMCgp100
You receive IMCgp100 as a drip into your bloodstream (intravenously). It takes about 15 to 20 minutes to have it. 
 
You have IMCgp100 every week. This continues for as long as it is helping you and the side effects aren’t too bad. You start with a low dose to check how you tolerate the treatment. You have a slightly higher dose for the second treatment and again at the third treatment. You then have this dose for the rest of the study.
 
The first 3 times you have IMCgp100, you stay in hospital overnight. Doctors want to monitor you and check for any side effects you may have.
 
Standard treatment
You have 1 of the following drugs:
  • dacarbazine
  • ipilimumab 
  • pembrolizumab
Your doctor can tell you which treatment you will have. 
 
You have dacarbazine and pembrolizumab as a drip into your vein, every 3 weeks. This continues for as long as the treatment is helping you and the side effects aren’t too bad. 
 
You also have ipilimumab as a drip into your vein every 3 weeks. You have up to 4 ipilimumab treatments. It takes around 3 months.
 
Quality of life 
Everyone taking part completes quality of life questionnaires before the start of treatment and then:
  • at set times during the trial 
  • after you finish treatment 
The questionnaires ask about how you have been feeling and what side effects you have had. 
 
Blood tests
You have some extra blood tests if you join the IMCgp100 group. Researchers want to:
  • find out what happens to IMCgp100 in your body
  • find out how much of IMCgp100 is in your body at certain times after treatment
  • look at how the immune system responds to IMCgp100
You have the extra blood tests before the start of treatment, at set times during the trial and when you finish treatment. 
 
Tissue sample
The trial team will ask to use a sample of your cancer taken at the time of your diagnosis (archival tumour sample). 
 
They ask you to have a biopsy Open a glossary item if there isn’t a suitable sample available. You don’t have to agree to have a biopsy if you don’t want to. 
 
Doctors want to look at the cancer and the proteins on the outside of cancer cells.  

Hospital visits

You see a doctor and have some tests before taking part. The tests might include:
  • a physical examination
  • blood tests
  • urine test
  • a CT scan or MRI scan
  • heart trace (ECG Open a glossary item)
During treatment, you see the trial team every week if you are in the IMCgp100 group. You see them every 3 weeks if you join the standard treatment group. You have blood tests and a physical examination every time you see them. 
 
You have a CT scan or MRI scan every 12 weeks (3 months). This continues for as long as the treatment is helping you and the side effects aren’t too bad. If you have ipilimumab, you have treatment for a maximum of 3 months. 
 
You see the trial team after you finish treatment. This is called the end of treatment visit. You have blood tests and a physical examination. You then see or speak with the trial team every 3 months. If you stop treatment before your cancer starts to grow again, you will continue to have CT scans or MRI scans every 12 weeks (3 months). 

Side effects

The trial team monitor you during treatment and afterwards. You have a phone number to call them if you are worried about anything. The team will tell you about the possible side effects before you start the trial. 
 
Doctors think that the most common side effects of IMCgp100 are:
  • rash, dry skin, red skin, skin sloughing and flaking, skin darkening, whitened skin or vitiligo
  • itching of skin and generalised itching or generalised rash or skin eruptions
  • swelling of the face, body and eyes 
  • fever and chills
  • fatigue or tiredness 
  • nausea, the feeling of throwing up and vomiting (throwing up)
  • low blood pressure
  • headache, dizziness and forgetfulness
  • low white blood cells (immune cells in the bloodstream)
  • pain in the abdomen (belly), extremities (arms or legs), pain in muscles, joints or bones
  • diarrhoea
  • flu like illness
  • elevations of liver enzymes and liver proteins in the bloodstream
  • decreased appetite
