Around 1 in 5 people diagnosed with cancer in the UK take part in a clinical trial.
A trial looking at vistusertib for diffuse large B cell lymphoma (TORCH)
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 vistusertib (AZD2014) for diffuse B cell lymphoma. It is for people with lymphoma that has continued to grow during treatment or has come back afterwards. Diffuse large B cell lymphoma (DLBCL) is a type of non Hodgkin lymphoma. It is the most common type of high grade non Hodgkin lymphoma.
More about this trial
Doctors usually treat DLBCL with chemotherapy and a drug called rituximab. Some people may have
For many people, these treatments get rid of the lymphoma cells (get it into
Vistusertib is a type of
The researchers are also looking at having vistusertib alongside rituximab in a small number of people. Researchers think rituximab may help vistusertib to work better. But they don’t know for sure.
The aims of this trial are to
- Find out If vistusertib helps people with diffuse large B cell lymphoma
- Find out if vistusertib and rituximab together is a useful and safe treatment
- Learn more about the side effects

This is a phase 2 trial. The researchers need 36 people to take part in total.
The trial is in 2 parts. 30 people are needed for part 1 and 6 people for part 2.
Everyone has vistusertib. The people in part 2 also have rituximab.
Vistusertib is a tablet. You take it twice a day. You have treatment for the first 2 days of each week and then 5 days without treatment. You have treatment for as long as it is helping you and the side effects aren’t too bad.
If you join part 2, you also have rituximab as a drip into a vein once a month for up to 6 months. It takes about 1 to 2 hours each time.
The researchers will also ask for extra blood samples and a sample of spit (saliva). They will use these samples to find out more about diffuse large B cell lymphoma. If you don’t want to give these samples for research, you don’t have to. You can still take part in the trial.
You see the doctor to have some tests before taking part in this trial. These tests include
- A physical examination
- Blood tests
- Urine tests
- Heart trace (
- Heart scan such as an
- PET-CT scan
If you haven’t had a tissue sample (
If you are having rituximab, you go to hospital to have it.
For the first 6 months of treatment, you go to hospital once or twice a month for a check up. After that you see the trial team once a month.
You have a PET-CT scan 2 months and again 6 months after starting treatment.
A month after finishing treatment, you see the trial team for a check up. They will repeat some of the tests you had before you joined the trial.
The trial team will follow you up every 3 to 4 months for a year to see how you are getting on. You have a CT scan at each check up.
As vistusertib is a new drug, 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 will be given a phone number to call them if you are worried about anything.
The most common side effects of vistusertib so far include
- Loss of appetite
- Tiredness (fatigue)
- Feeling or being sick
- Sore mouth or mouth ulcers
- Tummy pain
- Skin rash
- Low level of potassium or phosphate in your blood
- High blood pressure
- Muscle weakness
- Feeling thirsty all the time
- Problems concentrating
- Passing urine more often
It is possible that vistusertib may make you more sensitive to sunlight. You should avoid strong sunlight, sunbeds and tanning booths during treatment and for 3 months after your last treatment.
We have information on the side effects of rituximab.
