Obicetrapib hemicalcium
Obicetrapib hemicalcium (TA-8995 hemicalcium) is an orally active cholesteryl ester transfer protein (CETP) inhibitor. Obicetrapib hemicalcium shifts the plasma lipoprotein profile toward more HDL-C particles, reduces circulating PCSK9 levels, increases hepatic LDLR expression and LDLR mRNA levels, and promotes hepatic clearance of VLDL remnants. Obicetrapib hemicalcium increases the number of large HDL particles, reduces the number and area of atherosclerotic lesions and alleviates lesion severity, increases the proportion of unaffected arterial segments, improves lesion stability, and promotes regression of aortic root lesions. Obicetrapib hemicalcium also exerts a synergistic effect with Ezetimibe (HY-17376) to reduce non-HDL-C levels and improve atherosclerosis. Obicetrapib hemicalcium can be used in studies related to atherosclerosis and dyslipidemia.

Biological Activity
Obicetrapib (28 weeks) hemicalcium reduces non-HDL-C by enhancing LDL receptor-mediated VLDL clearance, strongly inhibiting atherosclerotic lesion progression by 90% and improving plaque stability in APOE*3-Leiden.CETP mice fed a Western-type diet[2].
