A Phase 3 interventional study of Obicetrapib and Placebo in Dyslipidemias, High Cholesterol and Hypercholesterolemia, sponsored by NewAmsterdam Pharma. Completed at 96 sites in 10 countries. Open to participants aged 18 Years and older. Per ClinicalTrials.gov, last updated 2025-06-11.
Sponsored by NewAmsterdam Pharma · Phase 3, Interventional, and Treatment
This study will be a placebo-controlled, double-blind, randomized, phase 3 study to Evaluate the Efficacy, Safety, and Tolerability of Obicetrapib in Participants with a History of Heterozygous Familial Hypercholesterolemia (HeFH).
This study will be a placebo-controlled, double-blind, randomized, phase 3 study in participants with HeFH to evaluate the efficacy, safety, and tolerability of obicetrapib as an adjunct to diet and maximally tolerated lipid-lowering therapy. The screening period for this study will take up to 14 days. Afterwards, patients will be randomized to placebo or 10 mg obicetrapib for an 365-day treatment period. After the treatment period, participants will have an end-of-study follow-up visit.
Exclusion Criteria:
one placebo tablet once daily
Drug: Placebo
one 10 mg Obicetrapib tablet once daily
Drug: Obicetrapib
10 mg Obicetrapib tablet
Also known as: CETP-inhibitor
