Around 1 in 5 people diagnosed with cancer in the UK take part in a clinical trial.
A trial of LJM716 with trastuzumab for breast or stomach cancer that is HER2 positive
Please note - this trial is no longer recruiting patients. We hope to add results when they are available.
This trial is looking at a new drug called LJM716 alongside trastuzumab (Herceptin) for HER2 positive cancer. It is for people who have breast cancer, stomach cancer or cancer where the food pipe (oesophagus) meets the stomach (gastro oesophageal junction cancer) that has spread to another part of the body.
Cancers with large amounts of a protein called
In this trial, researchers are looking at a drug called LJM716 alongside trastuzumab. LJM716 is a type of biological therapy called a monoclonal antibody. It stops signals that cancer cells use to divide and grow.
The aims of the trial are to
- Find the highest dose of LJM716 you can have safely
- Learn more about the side effects and what happens to the drug in your body
- See if it helps people with HER2 positive cancer
Who can enter
You may be able to enter this trial if
- You have breast cancer, stomach cancer or cancer where the food pipe (oesophagus) meets the stomach (gastro oesophageal junction cancer)
- Your cancer cannot be removed with surgery or has spread to another part of your body
- Your cancer has large amounts of the
HER2 protein(HER2 positive)
- You have already had at least one type of treatment that included trastuzumab (Herceptin)
- You are well enough to be up and about for at least half the day (performance status 0, 1 or 2)
- You have recovered from the side effects of earlier cancer treatment (apart from hair loss) – you can take part if you have nerve damage (peripheral neuropathy) as long as it is only mild
- You have satisfactory blood test results
- You are at least 18 years old
- You are willing to use reliable contraception during the trial and for at least 3 months afterwards if there is any chance you could become pregnant
As well as the above
- If you have breast cancer, you must have had between 1 and 3 treatments that target HER2 and your cancer got worse during the most recent treatment, which must have included either trastuzumab or a drug called lapatinib.
- If you have stomach cancer, you must have had 1 or 2 treatments that target HER2 and your cancer got worse during the most recent treatment, which must have included trastuzumab.
You cannot enter this trial if
- You have cancer that has spread to your brain and hasn’t been treated or is causing symptoms – you can take part if cancer spread to your brain has been treated with surgery or radiotherapy, is not getting worse and if you take steroids, the dose has been the same for at least 4 weeks
- You have any other cancer that needs treatment
- There isn’t an available sample of your cancer that was removed in the past
- You have already had treatment that targets a protein called HER3
- You have had any other anti cancer drugs (apart from trastuzumab) in the last 4 weeks (6 weeks if you had mitomycin C or a drug called a
nitrosourea), or earlier if there is any chance some of the drug could still be in your body
- You have had major surgery in the last 4 weeks or haven’t fully recovered from any type of surgery
- You have had radiotherapy in the last 2 weeks unless it was radiotherapy to a small area of your body to treat symptoms from cancer spread to your bones
- You have an
autoimmune diseasethat needs treatment other than a low dose of a steroidcalled prednisolone
- You have had a bad reaction to a drug made in a similar way to the trial drug – the trial team can advise you about this
- You have an infection that has needed treatment in the last 10 days
- You have certain heart problems – the trial team can advise you about this
- You have any other serious medical condition or mental health problem that the trial team think would make it unsuitable for you to take part
- You are known to have HIV, hepatitis B or hepatitis C
- You are pregnant or breastfeeding
This phase 1 trial will recruit at least 55 people. Everybody taking part has trastuzumab and LJM716. You have both drugs through a drip into a vein once a week.
The trial is in 2 parts. In the 1st part, the researchers want to find the highest safe dose of LJM716. The first few patients taking part will have a low dose of the drug. If they don’t have any serious side effects, the next few patients will have a higher dose. And so on, until they find the best dose to give. This is called a dose escalation study.
In the 2nd part of the trial, the researchers want to learn more about LJM716 and whether it can stop or slow down the growth of HER2 positive cancers. Everybody joining this part of the trial has the highest safe dose found in part 1.
As long as you don’t have bad side effects, you can carry on having the trial treatment for as long as it is helping you.
You see the trial team and have some tests before you start treatment. The tests include
- Physical examination
- Blood tests
- Urine test
- Heart trace (
- Heart scan (
echocardiogram) or MUGA scan
- CT scan or MRI scan
If your cancer has spread to your skin, the trial team will take a photograph. This will not include your face and it won’t be possible to identify you from the photo.
The researchers will get a sample of your cancer removed when you had surgery or a
If you join the 1st part of the trial, they may ask you to have another biopsy before you start having LJM716. But you don’t have to have this biopsy if you don’t want to. You can still take part in the trial.
If you join the 2nd part of the trial, you must be willing to have another biopsy before you start having LJM716.
You go to hospital
- Between 7 and 9 times in the first 4 weeks of treatment
- 4 times in the next 4 weeks
- Between 7 and 9 times in the following 4 weeks
- Once a week after that
You have regular blood tests and more heart traces throughout the treatment. You have a CT or MRI scan every 8 weeks. And if you have cancer spread to your skin, the trial team will also take photographs every 8 weeks.
People in the 2nd part of the trial may be asked to have 2 more biopsies. But these are optional. If you don’t want to have more biopsies, you can still take part in the trial.
Most hospital visits will last between 1 and 4 hours. A couple of visits early in your treatment will last 11 or 12 hours and you may need to stay in hospital overnight.
When you finish the treatment, the trial team will contact you a month later to see how you are.
If you stop the treatment for any reason other than your cancer getting worse, you continue to have a CT or MRI scan every 2 months until your cancer does start to get worse.
As LJM716 is a new drug, there may be side effects we don’t know about yet. The possible side effects include
- A reaction to the drug causing symptoms such as high temperature (fever), chills, feeling or being sick, headache, dizziness, difficulty in breathing, drop in blood pressure, rash, and lack of muscle strength
- Tiredness (fatigue)
- Sore mouth
- Feeling or being sick
- Loss of appetite
- Low levels of potassium and magnesium in the blood
To try to prevent a reaction, you have the LJM716 slowly over at least 2 hours. And you may have other medication such as paracetamol, an
We have more information about the side effects of trastuzumab.
It is possible that the side effects of trastuzumab may be different when you have it at the same time as LJM716. The trial team will talk to you about all the possible side effects of the drugs before you agree to take part.
