A trial looking at how INC280 affects caffeine and midazolam in people with solid tumours
Please note - this trial is no longer recruiting patients. We hope to add results when they are available.
A trial for people with solid tumours that have spread (
This trial is looking at how a drug called INC280 changes the way caffeine and midazolam are broken down by the body.
More about this trial
Researchers think a drug called INC280 can block the effects of the cMET gene and stop cancer cells from growing.
INC280 has been given to a small number of people but researchers want to find out more about. They want to see how this drug changes the way other drugs are broken down by the body.
In this trial, researchers are looking at 2 drugs
Caffeine is found in coffee, tea or chocolate. It is also found in
Midazolam is given to calm, or to make people sleepy and relaxed before medical tests (
The aims of this trial are to
- find out how caffeine and midazolam are broken down by your body after you have had INC280 (
- learn more about the side effects of INC280
- find out if INC280 can help people with advanced solid cancer that have a change on the cMET gene

- You are known to be sensitive to INC280, caffeine, midazolam or anything it contains
- You have recently taken drugs that affect some enzymes called CYP3A4, CYP1A2 (such as tobacco), can reduce the amount of acid in your stomach (proton pump inhibitors) or can affect your heart function
- You have taken a herbal remedy in the past 5 days or you have had foods with theobromine (such as chocolate), grapefruit or chargrilled meat in the past 3 days
- You have had more than 1 alcoholic drink every day in the past 3 days – 1 drink is 150 ml of wine or 360 ml of beer

This is an international phase 1 trial. The researchers need about 32 people to take part worldwide and hope that around 4 people from the UK will take part.
The first day of treatment is called day 1. Everyone has caffeine and midazolam on day 1. After this you have a break of 2 days where you do not take any drugs.
On day 4 you start the INC280 tablets. You take the tablets every day, twice a day. You cannot eat for at least 1 hour before the tablets and after you have had the tablets you must wait at least 2 hours before eating.
On day 9 you have caffeine and midazolam again. After that you have INC280 twice a day. You continue to take it for as long as it helps you and the side effects aren’t too bad.
You have some extra blood tests as part of this trial. The blood tests will be done before you take the drugs and then at set times during the trial.
Researchers will ask to store the blood samples and use them in future studies to look for substances called
You do not have to agree to have your blood stored if you don’t want to. You can still take part in the trial.
Before you start treatment the trial team need to check if your cancer has a change on the cMET gene. They will ask to use a tissue sample of your cancer taken either when you were diagnosed or during other treatments if available.
If there is not a suitable sample available the researchers will ask you to have one taken (
If you or your partner become pregnant during treatment, or 7 days after stopping INC280, the trial team will ask to look at the medical records of you, your partner and the baby until they are born.
Only people involved in this research will look at your records and your details will be removed so that no one will be able to identify you. You do not have to agree to the trial team doing this if you don’t want them to.
You see a doctor and have some tests before taking part. These tests include:
- A physical examination
- Heart trace (
- CT scan or MRI scan
- Bone scan
- Photograph of lesions (if you have cancer lesions on the skin)
- Blood tests
- Urine test
You see the doctor 9 days after you start the drugs and every 3 weeks after.
During each visit you have
- A physical examination
- Blood tests
- Heart trace (if needed)
Because of the extra blood tests (pharmacokinetics) you may need to stay in hospital for 2 nights. This would be on day 1 of treatment and then day 9. The trial team will give you more information about this.
You have a CT or an MRI scan every 6 weeks. This continues as long as your cancer stays the same and does not get worse. If your cancer gets worse, you stop INC280.
When you stop treatment you see the trial team
- after 7 days
- after 30 days
The trial team monitor you during the time you have treatment and you will be given a phone number to call them if you are worried about anything. The team will tell you about all the possible side effects before you start the trial.
