He begins this episode by sharing how his family history shaped his interest in lipidology and primary prevention. He explains why prevention should focus on causal drivers of disease rather than near-term risk and examines the causal relationship between LDL and atherosclerotic cardiovascular disease. Michael then traces the complicated history of CETP inhibitors—from the original rationale that raising HDL would reduce cardiovascular risk to the failures of torcetrapib, dalcetrapib, and evacetrapib—and explains how lessons from these trials ultimately led to the development of obicetrapib. He reviews the phase 2 and phase 3 trials of obicetrapib, its effects on LDL-C, apoB, LDL particle number, and Lp(a), the ongoing cardiovascular outcomes trial, and where the drug could fit alongside statins and other lipid-lowering therapies. Peter and Michael discuss the relationship between statins and diabetes risk, then turn to the potential role of obicetrapib in Alzheimer's disease prevention, exploring the genetics of APOE4 and CETP, cholesterol metabolism within the brain, and emerging biomarker data. Finally, Peter and Michael explore the benefits of omega-3 fatty acids and the challenge of delivering DHA to the brain, as well as ongoing work on klotho in preparation for clinical trials. They discuss the potential for AI to transform clinical trials and the scientific and financial challenges of developing new therapies for cardiovascular and neurodegenerative disease.
