In a groundbreaking study that could bridge cardiovascular and neurological health, NewAmsterdam Pharma has linked its investigational lipid-lowering drug obicetrapib with improved biomarkers of Alzheimer’s disease cognition. The findings, revealed at the 2024 ASCO conference and covered by Fierce Biotech, signal a potentially transformative moment in how clinicians may approach neurodegenerative disease prevention in patients with high cholesterol.

What Is Obicetrapib?
Obicetrapib is a CETP inhibitor—meaning it blocks the cholesteryl ester transfer protein involved in regulating HDL (“good”) and LDL (“bad”) cholesterol. Originally designed to tackle stubbornly high LDL levels, the drug has consistently demonstrated effectiveness in lipid management, especially for statin-intolerant patients or those needing additional cholesterol reduction beyond statins.
But in this new data, obicetrapib appears to be doing more than just improving lipid profiles—it may also influence how the brain ages.
The Link Between Lipids and Alzheimer’s
Alzheimer’s disease has long been associated with complex biological processes, including beta-amyloid plaques, tau protein tangles, inflammation, and increasingly, cholesterol metabolism.
Cholesterol plays a crucial role in neuronal function and brain cell membrane integrity. Elevated LDL cholesterol and impaired HDL function have been implicated in increasing the risk for Alzheimer’s disease, particularly in midlife. The theory is that excess LDL may contribute to vascular damage and inflammatory processes that accelerate cognitive decline.
Clinical Findings: Obicetrapib and Alzheimer’s Biomarkers
NewAmsterdam Pharma’s trial, part of its broader development plan for obicetrapib, showed measurable improvements in a recognized composite Alzheimer’s Disease biomarker. This includes markers tied to memory, attention, and processing speed—early indicators of cognitive decline in at-risk individuals.
Although full results have not been peer-reviewed, early signs point to a notable improvement in cognition-related biomarkers compared to placebo. This dual benefit—cholesterol lowering and possible neuroprotection—offers a novel therapeutic angle that has not been widely seen in other CETP inhibitors.
Implications for Cardiometabolic and Cognitive Health
If confirmed in larger, longer-term studies, the results could redefine how physicians treat patients who are at high risk for both cardiovascular and neurodegenerative diseases. Currently, many Alzheimer’s prevention strategies focus on behavioral interventions like diet, exercise, and cognitive training, while drug therapies remain limited and controversial.
Obicetrapib could potentially become a multitarget therapy that not only improves cardiovascular outcomes but also slows or prevents the onset of Alzheimer’s in high-risk patients—a significant breakthrough given the aging population.
This potential dual action is particularly relevant for:
- Middle-aged adults with elevated LDL cholesterol
- Patients with a family history of Alzheimer’s
- Those with metabolic syndrome or diabetes
- Statin-intolerant individuals seeking alternative treatments
The Broader CETP Inhibitor Landscape
CETP inhibitors have had a rocky history in clinical research. Drugs like torcetrapib and evacetrapib failed in late-stage trials due to lack of efficacy or safety concerns. However, obicetrapib seems to have sidestepped many of these pitfalls by using lower doses, a more favorable safety profile, and better cholesterol modulation results.
With its ongoing Phase 3 program (PREVAIL), NewAmsterdam aims to confirm not only cardiovascular benefits but potentially validate these cognition-related effects in larger populations.
What’s Next for Obicetrapib?
The next phase in clinical validation will be critical. To be taken seriously as a dual-purpose therapy, obicetrapib must demonstrate that biomarker improvements translate into real-world cognitive protection or delay in Alzheimer’s progression. This will require longitudinal studies, diverse patient populations, and rigorous neurocognitive testing.
But even now, the implications are clear: we may be entering an era where cholesterol drugs are not just for the heart—but also for the brain.
Expert Reactions
Though cautiously optimistic, many experts are intrigued. Dr. Steven Greenberg, a neurologist not affiliated with the study, remarked, “We’ve suspected for years that cholesterol and Alzheimer’s are connected, but seeing a drug alter cognitive biomarkers directly is an important development. It’s not proof, but it’s a door worth opening.”

Final Thoughts
As NewAmsterdam Pharma continues to explore the capabilities of obicetrapib, the medical community watches closely. If its cognitive benefits hold up under further scrutiny, it could fundamentally reshape how we view the intersection of cardiovascular and brain health.
Whether you’re managing your own cholesterol or concerned about Alzheimer’s in your family, this development underscores one core truth: what protects the heart may also protect the mind.
