AI summary
From the trial's eligibility criteria. Machine-read from the registry text on this page, so it can be wrong. The registry text below and the trial team decide who can take part.
The trial is looking for adults with cancer who are about to start immune checkpoint inhibitor treatment at The James Cook University Hospital. It studies heart blood tests using leftover routine blood samples.
- Age
- 18 years or older
- Sex
- All sexes
- Disease stage
- Cancer treated with an immune checkpoint inhibitor (PD-1, PD-L1, CTLA-4 or combination therapy).
- Earlier treatment
- People must be planned to start an immune checkpoint inhibitor treatment. They join at the start of this treatment or just before it.
Main reasons for not taking part
- A recent heart attack or similar sudden heart problem (acute coronary syndrome) within 1 month before joining
- Kidney failure that needs dialysis (people with kidney disease not on dialysis can join)

About the trial
What the trial wants to find out
Immune checkpoint inhibitors (ICIs) are widely used cancer treatments. Blood tests such as cardiac troponin and N-terminal pro-B-type natriuretic peptide (NT-proBNP) can help clinicians investigate possible heart injury, but these markers may also be raised for other reasons such as infection, kidney dysfunction, arrhythmia, pulmonary embolism or fluid overload. PRIME-ICI is a prospective observational study of adults starting ICI therapy at The James Cook University Hospital. The study will mainly use leftover blood from routine clinical samples and routine electronic health-record data. Samples will be batch tested for NT-proBNP, high-sensitivity troponin I and T, and selected exploratory biomarkers. The study will determine how often cardiac biomarkers are elevated, describe the clinical circumstances in which elevations occur, and classify biomarker-positive episodes according to their most likely clinical phenotype. Participation does not alter cancer treatment, and research biomarker results are not used for real-time clinical decisions.
The group in the trial
- Adults initiating immune checkpoint inhibitor therapy
Adults aged 18 years or older enrolled at, or immediately prior to, initiation of any ICI-containing treatment regimen at The James Cook University Hospital. Participants receive cancer treatment according to routine clinical care; the study does not assign treatment.

- Are travel costs paid?
- Can I keep my own doctor?
- What happens if I want to stop?
