DNV001 Injection in Patients With Hypercholesterolemia

This is a Phase II clinical study to evaluate the effectiveness and safety of different doses of DNV001 injection in patients with primary hypercholesterolemia or mixed dyslipidemia who have not achieved adequate control of low-density lipoprotein cholesterol (LDL-C) despite statin therapy. The study will enroll approximately 120 participants and will be conducted at 10-15 centers in China. Participants will be randomly assigned to one of four dose groups (50 mg, 150 mg, 300 mg-1, or 300 mg-2) or placebo, administered as subcutaneous injections. The study includes a 2-week screening period, a 4-week run-in period, a 36-week double-blind treatment period, and a 12-week follow-up period, for a total of up to 54 weeks. The main goal is to see how much DNV001 lowers LDL-C levels after 24 weeks of treatment. The study will also look at long-term effectiveness, safety, how the body processes the drug, and whether it causes an immune response. All participants will continue taking their stable dose of statin medication throughout the study.
