Double-Drug attack on cholesterol: could two be better than one?
NCT ID NCT07581808
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at whether combining two different cholesterol-lowering drugs (inclisiran and alirocumab) works better than using either alone. About 60 adults with high heart risk who cannot take statins will be assigned to one of three groups. The goal is to see if the combo lowers 'bad' cholesterol more effectively and safely over 9 months.
