What is the purpose of this trial?

This trial tests a new pill, obicetrapib, to determine if it can lower bad cholesterol levels in individuals with high cholesterol due to genetic factors or heart disease. The trial compares obicetrapib to a placebo (a pill with no active ingredients) to assess its effectiveness and safety. Individuals with genetic high cholesterol or heart disease who are already on medications like statins but still require better cholesterol control may find this trial suitable. As a Phase 3 trial, it represents the final step before FDA approval, providing an opportunity to contribute to the development of a potentially groundbreaking treatment.

Will I have to stop taking my current medications?

The trial requires participants to be on a stable dose of their current lipid-lowering medications, like statins, for at least 8 weeks before joining. You should not stop taking these medications if you want to participate.

Is there any evidence suggesting that obicetrapib is likely to be safe for humans?

Research has shown that obicetrapib is generally well-tolerated. One study compared obicetrapib to a placebo (a harmless pill with no active drug) and found a similar number of unwanted side effects in both groups. Another review of several studies found that obicetrapib has a good safety record, indicating it did not cause many serious side effects. However, researchers have not fully studied the safety of obicetrapib in all types of patients, so unknown risks may still exist. Overall, early findings suggest that obicetrapib is safe for most people. ^{1 2 3 4 5}

Why do researchers think this study treatment might be promising?

Unlike the standard of care for high cholesterol, which typically involves statins like atorvastatin or rosuvastatin, obicetrapib works by inhibiting cholesteryl ester transfer protein (CETP). This mechanism is different because it aims to not only lower LDL cholesterol but also potentially increase HDL cholesterol, providing a twofold benefit. Researchers are excited about obicetrapib because it could offer an alternative for patients who cannot tolerate statins or need additional cholesterol-lowering effects beyond what statins can provide.

What evidence suggests that obicetrapib might be an effective treatment for high cholesterol?

Research has shown that obicetrapib, which participants in this trial may receive, effectively lowers bad cholesterol (LDL-C) levels. In studies, participants taking obicetrapib experienced a reduction in LDL-C by about 29.9% to 35.4%. It also increases good cholesterol (HDL-C) and reduces other harmful fats in the blood, making obicetrapib a promising option for people with high cholesterol, especially those at risk for heart problems. The treatment improves lipid profiles, which are important for heart health. ^{1 2 4 5 6}

Are You a Good Fit for This Trial?

This trial is for adults with high cholesterol or heart disease who are already on the highest dose of cholesterol-lowering meds they can handle. They should have a specific genetic condition (HeFH) or a history of cardiovascular disease, and their kidneys must work well. Pregnant or breastfeeding women, or those planning to become pregnant during the study, cannot participate.

Inclusion Criteria

Your fasting triglyceride levels are within a certain range.

My cholesterol or other risk factors meet the study's criteria.

I have been on a stable dose of the highest statin dose I can tolerate for at least 4 weeks.

Exclusion Criteria

Your thyroid-stimulating hormone levels are higher than 1.5 times the normal limit.

Your blood sugar levels are very high, with HbA1c at 10% or fasting glucose at 270 mg/dL or more.

I have an ongoing liver condition.

What Are the Treatments Tested in This Trial?

Interventions

• Obicetrapib
• Placebo

Trial Overview

The trial is testing Obicetrapib's effectiveness when added to existing treatments for lowering cholesterol compared to a placebo. It's in phase 3, meaning it's closer to potentially being approved if results are positive. Participants won't know whether they're getting the real drug or a dummy pill.

How Is the Trial Designed?

Group I: obicetrapib 10mg Experimental Treatment 1 Intervention

one 10mg obicetrapib tablet once daily

Group II: Placebo Placebo Group 1 Intervention

one placebo tablet once daily

In a phase 2 trial with 97 patients, the combination of obicetrapib and ezetimibe significantly reduced LDL cholesterol levels by 63.4% compared to only 6.35% in the placebo group, demonstrating strong lipid-altering efficacy.

Obicetrapib was well tolerated with no safety issues reported, indicating that it is a safe adjunct therapy when added to high-intensity statin treatment for patients with elevated LDL cholesterol.

In a study of 850 patients with familial hypercholesterolemia, adding torcetrapib to atorvastatin significantly increased HDL cholesterol levels but did not improve the progression of atherosclerosis, as measured by carotid intima-media thickness.

The combination therapy actually led to a worsening in the common carotid artery's thickness, indicating that despite lowering LDL cholesterol and raising HDL cholesterol, torcetrapib did not provide the expected cardiovascular benefits.

In a randomized, double-blind, placebo-controlled trial involving 120 dyslipidaemic patients, the CETP inhibitor obicetrapib significantly reduced LDL cholesterol levels by up to 51% over 8 weeks when added to high-intensity statin therapy.

Obicetrapib also decreased apolipoprotein B and non-HDL cholesterol levels while increasing HDL cholesterol by up to 165%, demonstrating its potential as an effective treatment for high-cardiovascular-risk patients with an acceptable safety profile.
