A Trial to Evaluate the Efficacy and Safety of DR10624 in Patients With Hypertriglyceridemia and Carotid Atherosclerotic Plaque

This is a researcher-initiated study to evaluate the effect of DR10624 injection on carotid atherosclerotic plaques in patients with hypertriglyceridemia and carotid atherosclerotic plaques. The study adopts a randomized, double-blind, placebo-controlled design. The treatment group has one dose group, with titration administration. The administration starts at 12.5 mg QW for 4 weeks, then titrates to 25 mg QW for 4 weeks, and finally to 50 mg QW for 16 weeks, totaling 24 administrations. The control group receives placebo treatment with the same volume and administration method as the treatment group. The study is divided into a screening period (3 weeks), a treatment period (24 weeks), and a follow-up period (4 weeks). Screening period (W-3 to W-1): Before participating in the screening, the subjects must fully understand all the risks and possible benefits of the trial and sign a written informed consent form voluntarily. Subjects entering the screening period will also receive therapeutic lifestyle guidance. Two fasting serum triglyceride tests are required during the screening period, with one test completed within one week before the first administration and an interval of at least one week between the two tests. On the day before the treatment period (D-1), eligible subjects will be randomly assigned and receive a randomization number. Treatment period (W0 to W24): Subjects who pass the screening will enter the treatment period and receive the target dose through titration. They will receive DR10624 injection at 12.5 mg QW or placebo QW for 4 weeks (W0 to W3), then at 25 mg QW or placebo QW for 4 weeks (W4 to W7), and finally at 50 mg QW or placebo QW for 16 weeks (W8 to W23), totaling 24 administrations over 24 weeks. Subjects need to return to the research center weekly for drug administration during W0 to W23. After each administration, injection site observations are required (30 minutes (±10 minutes) and 1 hour (±10 minutes) after each administration
