Purpose of trial
The aim of the trial is to test whether a new targeted drug, GSK525762, is safe and effective for people with lymphoma or another blood cancer that has relapsed (come back) or didn’t respond (was refractory) to treatment.
There are 2 parts to this trial. You may enter at either part 1 or part 2.
- Part 1 is to find out the highest safe dose of GSK525762. This is done by ‘dose escalation’. Participants are treated in groups of 3. The first 3 participants have the lowest dose. The next 3 have a higher dose. This continues and the participants are monitored closely for side effects. The highest dose that doesn’t cause serious side effects is used in part 2 of the trial.
- Part 2 follows on from Part 1 and will test how well the highest safe dose of the study drugs works. People entering this part of the trial all have the same dose of study drugs.
You take GSK525762 as tablets by mouth. Most people take the tablets once a day. Some people might take the tablets twice a day.
You continue to take the trial treatment as long as you are responding well and not having any serious side effects.
The trial is recruiting people with all types of lymphoma, including at least 10 people with double-hit or triple-hit lymphoma.
The trial team may test a sample from a previous biopsy to confirm your diagnosis.
