NCT ID NCT03381287
First seen Aug 11, 2026 · Last updated Aug 12, 2026 · Updated 1 time
Summary
This trial evaluates an experimental drug called HTD1801 in overweight or obese adults with high cholesterol. The study aims to see if the drug is safe and tolerable when taken daily at different doses, and how the body processes it. Participants are randomly assigned to receive either HTD1801 or a placebo, and researchers monitor for side effects and measure drug levels in the blood.

- HTD1801 tablets
- What this could lead to
- If successful, HTD1801 could become a new oral treatment to help manage high cholesterol, potentially reducing the risk of heart disease.
- What could go wrong
- This is an early-stage trial focused on safety and dosing, not proof of effectiveness. The drug may not lower cholesterol as hoped or may cause side effects.
