Who is the study for?
This trial is for adults with high cholesterol, specifically those with a genetic condition called HeFH or who have heart disease or are at high risk for it. They should already be on the strongest dose of cholesterol medicine they can handle and still have LDL (bad) cholesterol over 70 mg/dL or HDL (good) cholesterol over 100 mg/dL.
What is being tested?
The study tests a new combo pill containing Obicetrapib and Ezetimibe against placebos in people taking their usual cholesterol meds. It's to see if this pill helps lower bad cholesterol more effectively. Participants won't know if they're getting the real treatment or a dummy pill.
What are the potential side effects?
Possible side effects include typical reactions to lipid-lowering drugs like muscle pain, liver problems, increased blood sugar levels, and digestive issues. Since it's double-blind, even researchers don't know who gets what which helps measure true side effects.
