What is ZAVZPRET (Zavzetrapib)?

ZAVZPRET is a proprietary CETP (Cholesteryl Ester Transfer Protein) inhibitor designed to increase HDL cholesterol and reduce LDL cholesterol levels, aiming to mitigate cardiovascular risk. Its development traces back to collaborations between biotech firms and major pharmaceutical companies, targeting unmet needs in lipid management.

• Mechanism of Action: CETP inhibition enhances reverse cholesterol transport, potentially reducing atherosclerotic plaque burden.
• Therapeutic Indication: Primarily indicated for hypercholesterolemia and secondary prevention of major adverse cardiovascular events (MACE).
