Study of laroprovstat (AZD0780) tablets to lower cholesterol levels in adults with inherited high cholesterol condition (heterozygous familial hypercholesterolemia)

3 1

What is this study about?

This study focuses on people with Heterozygous Familial Hypercholesterolemia, an inherited condition that causes high levels of LDL cholesterol (often called “bad” cholesterol) in the blood. The research evaluates a new medication called AZD0780 (laroprovstat), which is given as a film-coated tablet that patients take by mouth.

The purpose of this study is to determine how well AZD0780 works compared to placebo in lowering LDL cholesterol levels in patients who already take other cholesterol-lowering medications. The study will last for 52 weeks, during which participants will receive either AZD0780 or placebo in addition to their usual cholesterol-lowering treatments.

Throughout the study, researchers will monitor changes in various types of cholesterol and related substances in the blood, including apolipoprotein B, non-HDL cholesterol, total cholesterol, and lipoprotein(a). The main focus will be on measuring how much the LDL cholesterol levels change after 12 weeks of treatment.

1 Initial treatment period

You will receive either AZD0780 tablets or a placebo (a tablet that looks the same but contains no active medicine). Neither you nor your doctor will know which treatment you are receiving.

You will need to continue taking your current cholesterol-lowering medications throughout the study.

The treatment will be taken orally (by mouth) according to the prescribed schedule.

2 12-week assessment

After 12 weeks of treatment, your cholesterol levels will be measured to evaluate how well the medication is working.

The main focus will be on measuring your LDL-C (low-density lipoprotein cholesterol, often called ‘bad’ cholesterol).

Blood samples will be taken to measure various types of cholesterol and related substances in your blood.

3 28-week follow-up

Your cholesterol levels will be checked again after 28 weeks of treatment.

This assessment will help determine the longer-term effects of the medication.

4 52-week completion

The final assessment will occur after 52 weeks (one year) of treatment.

Your cholesterol levels will be measured one last time to evaluate the long-term effectiveness of the treatment.

Various measurements will be taken, including LDL-C, Apo B (a protein in lipoproteins), and other cholesterol-related substances.

Who Can Join the Study?

Trial locations

AZD0780 is an investigational medication being studied for its effects on lowering LDL cholesterol (often called “bad” cholesterol) in patients with an inherited condition that causes high cholesterol levels. The medication is being tested to see if it can help patients with a genetic condition called heterozygous familial hypercholesterolemia, which causes abnormally high cholesterol levels that can be difficult to treat with standard medications.

Heterozygous Familial Hypercholesterolemia – A genetic condition that causes high levels of LDL (bad) cholesterol from birth. People with this condition inherit one defective gene from one parent, affecting their body’s ability to remove cholesterol from the blood. It leads to consistently elevated cholesterol levels throughout life, particularly affecting LDL cholesterol. The condition results in the build-up of fatty deposits in blood vessels over time. The disorder affects the body’s ability to process cholesterol normally due to problems with specific proteins called LDL receptors.
