Purpose of trial
This is a platform study, which means it can test several different treatments in several different diseases at the same time. It aims to find out if different targeted drugs could be safe and effective for people with high-grade non-Hodgkin lymphoma that has not responded (refractory) or has come back (relapsed) after previous treatment.
Initially, the trial is looking at acalabrutinib, in combination with one of two new treatments (AZD9150 and AZD6738), in people with relapsed or refractory high-grade non-Hodgkin lymphoma (including diffuse large B-cell lymphoma or DLBCL).
In future, other targeted drugs or different types of lymphoma might be added to the study.
Participants are given one of two treatments:
- acalabrutinib plus AZD9150
- acalabrutinib plus AZD6738.
You are told which treatment you are having and given information about it. If you have to stop the study treatment for any reason, you might be assessed to see if you are suitable for the other treatment.
- AZD9150 is a cell signal blocker that targets a protein called STAT3. It works by blocking signals that tell cancer cells to grow, divide and survive.
- AZD6738 is a cell signal blocker that targets a protein called ATR. It works by blocking signals that tell cancer cells to repair themselves. This can make the cancer cells die.
- Acalabrutinib is a cell signal blocker that targets a protein called BTK.It works by blocking signals that help B cells to stay alive and divide.
You have AZD9150 as an intravenous infusion (by a drip into a vein). You have it three times in the first week of treatment and once a week from then on. You carry on having the treatment for up to 2 years unless your lymphoma gets worse.
You take AZD6738 and acalabrutinib orally (as capsules taken by mouth) twice a day.
Who can enter
