“I think it’s really important that people keep signing up to these type of trials to push research forward.”
A trial looking at vistusertib for diffuse large B cell lymphoma (TORCH)
This trial was for people whose lymphoma got worse during treatment or came back afterwards. People who had had a
The trial was open for people to join between 2015 and 2017. The team published the results in 2019.
More about this trial
Diffuse large B cell lymphoma (DLBCL) is the most common type of non-Hodgkin lymphoma. Chemotherapy and a drug called rituximab is the usual treatment. Some people may have
For many people, these treatments get rid of the lymphoma cells (get it into
Vistusertib is a type of
In a small number of people the researchers also looked at whether having vistusertib alongside rituximab would be better than having it on its own. The researchers thought rituximab may help vistusertib to work better. But they didn’t know for sure.
The main aims of this trial were to:
- find out if vistusertib works for 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
Summary of results
The trial team didn’t find that vistusertib worked as well as they had hoped for people whose DLBCL had got worse during treatment or had come back afterwards.
About this trial
36 people took part in this trial. 30 had vistusertib only and 6 had vistusertib and rituximab. They had treatment for up to 6 cycles. Each
The team looked at how well treatment worked in everyone who took part. They found:
- in 2 people the lymphoma went away a little bit
- in 7 people the lymphoma stayed the same
- in 27 people the lymphoma got worse
The people whose lymphoma went away a little bit had vistusertib on its own. The response lasted for 57 days in 1 person and 62 days in the other.
Vistusertib only group
The team found that on average it was just under 2 months before the cancer started to grow again. They also looked at how long people lived. On average this was just under 7 months.
Having vistusertib with or without rituximab didn’t cause too many side effects.
The most common side effects of vistusertib were:
- feeling sick or being sick
- tiredness (fatigue)
- sore mouth
The trial team found that vistusertib didn’t work as well as they had hoped in this group of people. These results weren’t better than other similar treatments for lymphoma. But vistusertib didn’t cause too many side effects and it was safe to have with rituximab.
All trial results help doctors and researchers understand more about different cancers and the best way to treat them.
