Summary

This trialaims to find out if reducing the accumulation of a substance in CKD patients that increases the risk of cardiovascular events can reduce their risk.

Who is the study for?
This trial is for adults aged 35-75 with moderate to severe chronic kidney disease (stages 3 and 4), who have a specific level of kidney function. It's not open to those with heart failure, severe anemia, HIV, pregnant or breastfeeding women, very low blood pressure or high resting heart rate, current smokers, cancer patients undergoing treatment, or those on certain medications.
What is being tested?
The study tests if L-arginine infusion can reduce overactivity in the nervous system among CKD patients by counteracting ADMA accumulation. Participants will either receive this amino acid or a placebo in order to compare outcomes.
What are the potential side effects?
L-arginine may cause minor side effects like gastrointestinal discomfort and bloating. In some cases it could lead to allergies or changes in blood sugar levels. The exact side effects will be monitored closely during the trial.
