Attenuating Calciprotein particles Transformation and Inhibiting Vascular calcification Evolution by Sodium ThioSulphate trial
When kidneys fail, people need regular dialysis to clean their blood. However, dialysis patients often have trouble balancing minerals like calcium and phosphate. Over time, these minerals can stick to the walls of blood vessels and cause them to harden, a condition known as vascular calcification. This hardening puts extra strain on the heart. This early-stage study is testing a treatment called sodium thiosulphate. Researchers want to find out if giving this medicine through the dialysis machine helps prevent calcium particles from clumping together in the blood. Participants will have some dialysis sessions with the medicine and some without it. Doctors will test their blood before and after treatment to see how well the medicine protects their blood vessels and controls mineral levels.
At a glance
What is this study about?
Our blood vessels need to stay flexible so blood can flow easily around the body. For people with kidney disease who need dialysis, keeping arteries healthy can be difficult. The kidneys normally balance minerals like calcium and phosphate. When they cannot do this job, these minerals can build up in the bloodstream and stick to blood vessel walls. Over time, the blood vessels become stiff and chalky, which doctors call vascular calcification. This makes it harder for the heart to pump blood and increases the risk of heart disease.
Researchers in this trial are testing a medicine called sodium thiosulphate. They believe this medicine might act like a shield, stopping calcium and protein particles in the blood from turning into hard crystals. If it works, it could help keep blood vessels softer and healthier in people who rely on dialysis.
During the trial, doctors will measure special markers in the blood called calciprotein particles, as well as a blood test called T50, which measures how well the blood resists calcification. By comparing blood samples taken before and after dialysis, the research team can see whether sodium thiosulphate makes a real difference in protecting blood vessels.
Key takeaways
- Tests whether sodium thiosulphate stops blood vessels from hardening.
- Aimed at adults currently receiving regular kidney dialysis.
- Medicine is given directly through the dialysis machine during routine sessions.
- Requires blood tests before and after dialysis to track mineral changes.
- Taking part is completely voluntary and will not affect your standard care.
Who may be eligible?
This study is open to adults aged 18 and older who are receiving regular dialysis treatment for kidney disease. Both men and women can take part.
Because this study focuses on how blood vessels react during dialysis, participants must already be on a stable dialysis routine. Your kidney care team will check your overall health and medical history to make sure taking part is safe for you.
People who have certain severe medical conditions, unusual allergies, or who are taking medicines that might react with sodium thiosulphate may not be able to join. Your doctor can look at your personal medical records to confirm if this study is right for you.
Could this study suit you?
Answer these quick questions to see if you may be eligible. This is a guide only — the research team makes the final call.
- I am aged 18 or older.
- I currently receive regular kidney dialysis.
- I am willing to have blood samples taken during my dialysis sessions.
- I am able to attend my scheduled dialysis appointments.
- My kidney specialist agrees that joining a trial is safe for me.
What does participation involve?
If you take part, your treatment will fit into your usual dialysis schedule, meaning you should not need extra visits just for the trial. During some of your scheduled sessions, the study medicine (sodium thiosulphate) will be given to you through your dialysis line. During other sessions, you will receive standard dialysis without the medicine so doctors can compare the results.
Before and after these dialysis sessions, the clinical team will take small blood samples. These tests will measure mineral levels, signs of inflammation, and how your blood handles calcium. The trial takes place over several planned dialysis sessions, and the study team will monitor your blood pressure and general wellbeing throughout the process. Your care team will explain the exact number of weeks the trial will last before you decide to join.

Common questions
What is vascular calcification?
It is when minerals like calcium build up inside blood vessel walls, making them stiff and hard instead of stretchy and flexible.
How is the trial medicine given?
Sodium thiosulphate is given directly into your bloodstream through your dialysis equipment, so you will not need extra injections.
Will I have to travel to a different hospital?
Usually, the study is carried out at your regular dialysis unit or a participating hospital clinic during your routine appointments.
Does this trial replace my normal dialysis?
No. You will still receive your full, regular dialysis treatment to clean your blood as usual.
Can I leave the study if I change my mind?
Yes. You can stop participating at any point, and your standard kidney treatment will carry on just as before.
