This is a phase 1/2 trial. It has 2 parts. The team need 150 people to join.
- Part 1 is looking at the best dose of HTL0039732 to have on its own or with atezolizumab. This is the dose escalation phase.
- Part 2 is looking at HTL0039732 to have with other cancer drugs. This is the dose expansion phase.
Part 1 (group A dose escalation). This group is now closed to recruitment.
This part is looking at the best dose of HTL0039732 to have on its own. The best dose is the highest dose with the fewest side effects. The first few people have a low dose. The next few people have a higher dose if they don't have any side effects. And so on until they find the best dose to give.
You have treatment in cycles
that last 3 weeks.
HTL0039732 is a capsule. You take:
- a dose about a week before the first cycle of treatment and then
- you take the capsules every day. The team will tell you how many to take.
You swallow the capsules whole with a glass of water. The team may ask you to not eat or drink anything (except water) for 2 hours before you take your capsules and for 1 hour afterwards. The team let you know how many capsules to take and when to take them. This depends on when you join the trial.
You have HTL0039732 for up to a year as long as it is working and the side effects aren’t too bad.
Part 1 (group B dose escalation)
It is looking at the best dose of HTL0039732 to have with atezolizumab.
You have:
- HTL0039732 on its own for the first 3 weeks and then
- you continue to have it with atezolizumab
You have HTL0039732 once a day, every day. You have atezolizumab as a drip into a vein, once every 3 weeks.
You have HTL0039732 and atezolizumab for up to a year.
Part 2 (dose expansion)
This part won’t start until part 1 (group A and group B) are complete.
You have HTL0039732 in combination with other cancer drugs. We’ll add more information about this part of the trial when it opens.
Samples for research
In part 1, group B, the researchers ask you to give an extra tissue sample before you start treatment and one extra sample during the trial. You need to say yes to this to join this part.
The team ask everyone to give some extra blood samples. Where possible, you have these at the same time as your routine blood tests. They also ask for some urine samples.
The researchers plan to use the samples to:
- look at genes
to understand more about your cancer type
- look for substances to help work out why treatment might work for some people and not for others
- see what happens to treatment in the body
