This phase 1/2 trial is taking place in the UK. There are 2 parts. Part 1 is looking at the best dose of TT-702 to have. Part 2 is testing this dose in more people.
Part 1 (dose expansion part) – this is open
The team need 44 people to join part 1. The first few people taking part have a low dose of TT-702. The next few people have a higher dose if they didn’t have any serious side effects. And so on, until they find the best dose. This is a dose escalation trial.
Part 2 (dose expansion part) – this isn’t open yet
The team need 90 people to join part 2. When they find the best dose in part 1 then part 2 can begin. This part tests the best dose in a larger number of people. There are 3 groups:
Everyone in part 2 has the same dose of TT-702.
How you have treatment
TT-702 is a tablet or capsule. To begin with, you have a one off dose. You have this between 3 and 9 days of starting your first cycle of treatment.
You have this initial dose at the hospital. After taking this dose you will need to stay in hospital for 1 or 2 nights. You have a number of blood tests taken to see what happens to TT-702 in the body.
When you start your first cycle of treatment, you take TT-702 once a day every day. You have treatment for up to a year as long as it is working and the side effects aren’t too bad.
The number of tablets or capsules you take depends on when you join the trial. You fill in a medication diary. You record when you take your medication and how much you take.
On some of the days you attend the hospital, the team may ask you to bring your TT-702 in with you and take them when you are at your visit. This is likely to be on the days that you are having extra blood tests for research. The trial nurse will mark these days on your diary card.
You stop treatment if your cancer gets worse. The trial doctor will talk to you about other treatment options.
Blood and tissue samples for research
The team ask you to give some extra blood samples. Where possible, you have these at the same time as your routine blood tests.
They plan to use the samples to:
- see how well the treatment is working
- see what happens to TT-702 in the body
- look for substances called biomarkers
to help work out why treatment might work for some people and not for others
- look at genes
on the cancer cells
You don’t have to give all the extra samples if you don’t want to. You can still take part in the main trial.
Depending on when you join the trial you might need to give some extra tissue samples. The trial team will let you know if this applies to you.
