简要总结
This is a randomized, double-blind, placebo-controlled Phase II trial evaluating the efficacy and safety of oral SAL0137 in adults with elevated Lp(a) and high cardiovascular risk. Participants will be randomized 1:1:1:1 to receive low-dose SAL0137, medium-dose SAL0137, high-dose SAL0137, or placebo for a treatment period of 12 weeks. The study assesses changes in Lp(a) levels and safety parameters.

- •History of acute kidney injury within 12 months prior to screening;
- •Uncontrolled hyperthyroidism or hypothyroidism;
- •Uncontrolled type 1 or type 2 diabetes mellitus within 6 months prior to screening (including diabetic ketoacidosis or hyperglycemic hyperosmolar state, or HbA1c > 8.5% at screening);
- •Active infection requiring systemic anti-infective therapy (oral or intravenous) prior to randomization, and the infection has not clinically resolved or still requires continued anti-infective treatment prior to randomization;
- •New York Heart Association (NYHA) Class III or IV cardiac function prior to screening;
- •Lipoprotein apheresis within 3 months prior to screening, or planned during the study period;
- •Use of weight-loss medications (see Appendix 3) or undergone surgery causing weight instability within 2 months prior to screening;
- •Long-term continuous or repeated use of systemic glucocorticoids within 3 months prior to screening;
- •Known allergy to the active ingredient or any excipients of SAL0137;
- •Uncontrolled hypertension at screening or prior to randomization (office sitting systolic blood pressure ≥ 160 mmHg and/or office sitting diastolic blood pressure ≥ 100 mmHg);

- •Any other reasons that, in the investigator's opinion, may affect the evaluation of efficacy and/or safety of this study, or make the participant unsuitable for participation in this clinical trial (including but not limited to poor compliance as judged by the investigator, or remote residence precluding scheduled follow-up visits).
