Randomized, controlled, double-blind trial to investigate the effect of colchicin on the endothelial function in patients with CHIP mutations and chronic heart failure with reduced left ventricular function (CHIP-HF)
This study is investigating if a medication called colchicine can improve blood vessel function in people who have chronic heart failure, where the heart doesn't pump blood as well as it should. Researchers are particularly interested in patients who also have a genetic change known as a CHIP mutation. Half the participants will receive colchicine, and the other half will receive a dummy pill (placebo). The main aim is to measure how blood vessels respond after treatment to see if colchicine makes a difference, especially for those with the CHIP mutation. It's an early-stage study to learn more about the treatment's potential.
At a glance
What is this study about?
This research study is looking into a condition called chronic heart failure. This happens when your heart muscle isn't pumping blood around your body as strongly as it should. It's a common condition, and doctors are always searching for new ways to help people manage it and feel better.
The study wants to see if a medicine called colchicine can improve how well your blood vessels work. Colchicine is a drug that's already used for other conditions, but its effects on heart failure, especially in people with certain genetic changes, aren't fully understood. Some people have a genetic change, called a CHIP mutation, which might affect how their heart condition progresses. Researchers specifically want to understand if colchicine helps these people.
In this study, some people will receive colchicine, while others will receive a 'dummy pill' or placebo. This helps the researchers accurately compare the effects of the actual medicine with no treatment. By doing this, they hope to find out if colchicine could be a useful treatment to improve blood vessel health in people with this type of heart failure, particularly if they have the CHIP genetic change.
Key takeaways
- This study is for people with chronic heart failure where the heart doesn't pump well.
- It tests a medicine called colchicine against a dummy pill (placebo).
- Researchers are interested in how colchicine affects blood vessels, especially in people with a certain genetic change (CHIP mutation).
- It's an early-stage study to see if colchicine could be a future treatment.
- Your health will be closely monitored if you participate.
Who may be eligible?
To join this study, you must be at least 18 years old. Both men and women can take part. You must have chronic heart failure where your heart doesn't pump blood as well as it should (doctors call this 'reduced left ventricular function').
The research team will also check if you have a specific genetic change, known as a CHIP mutation. This is a key part of the study, as they want to see how colchicine affects people with and without this particular genetic feature.
There will be other health checks to make sure the study is safe for you and that the results will be clear. A doctor on the study team will explain all the requirements and check if you are a suitable match.
- Are you 18 years old or older?
- Have you been diagnosed with chronic heart failure where your heart's pumping is reduced?
- Are you happy to have genetic testing for a CHIP mutation?
- Are you able to attend regular clinic visits and take medication?
- Are you prepared for a study that involves either active medication or a dummy pill?
This is a guide only — the research team will confirm whether you can take part.
What does participation involve?
If you decide to take part, you will be given either the study medicine (colchicine) or a dummy pill (placebo) in capsule form. You won't know which one you are taking, and neither will your study doctor, to ensure the results are unbiased. You will need to attend several visits to the study clinic. During these visits, the research team will perform various tests, including measurements of your blood vessel function (called FMD measurements). They will also take blood samples and monitor your general health.
Taking part might involve taking the medication for a period, typically several weeks or months. After you finish taking the study medicine, there will be follow-up appointments to check on your health and any effects of the treatment. The total duration of your participation, including follow-up, will be explained fully by the study team.

Common questions
What is chronic heart failure?
It's a long-term condition where your heart can't pump enough blood around your body as it should.
What is a 'CHIP mutation'?
It's a specific change in your genes that some people have, and researchers are looking at how it might affect heart failure.
What is colchicine?
It's a medication that's used for other conditions, and this study is looking at if it can help with heart failure.
What is a placebo?
A placebo is a 'dummy pill' that looks like the real medicine but contains no active drug. It helps researchers compare results accurately.
Will I know if I'm taking the real medicine or the placebo?
No, neither you nor your study doctor will know during the study. This is called 'double-blind' and helps make the results fair.
How to find out more
