This phase 1 trial is taking place in the UK. The team need up to 42 people to take part.
Everyone has chemoradiotherapy and tolinapant.
Standard chemoradiotherapy
You have radiotherapy for 5 weeks. You have this once a day, Monday to Friday.
You have cisplatin chemotherapy as a drip into a vein. You have this once a week for 5 weeks when you start radiotherapy.
After chemoradiotherapy you have internal radiotherapy (brachytherapy). This is also part of your routine care. The team will let you know how many sessions you have and when you have this.
Tolinapant
Tolinapant is a capsule. The number of capsules you take depends on when you join the trial. You start taking them on the same day you start chemoradiotherapy. You take the capsules once a day, every day during:
The first few people taking part have a low dose of tolinapant. The next few people have a higher dose if they don’t have any side effects. And so on until you find the best dose to give. This is dose escalation.
Scans
You have regular scans during the trial. These are part of your routine care. You would have them even if you weren’t taking part in the trial.
You have an MRI scan
:
- before starting treatment
- at week 5
- during a follow up visit
Samples for research
The researchers ask to take an extra sample of cancer tissue (biopsy
). They also ask for some urine samples and extra blood samples. Where possible, you have these blood samples done at the same time as your routine blood tests.
They plan to use the samples to:
- see what happens to tolinapant in the body
- look at genes
to understand more about cervical cancer
- measure circulating tumour DNA (ctDNA
) in the blood
- look for substances called biomarkers
to help work out why treatment might work for some people and not for others
You can say no to giving these samples. It won’t affect you taking part in the rest of the trial.
