摘要
MK-0616, a novel oral macrocyclic peptide inhibitor of proprotein convertase subtilisin/kexin type 9 (PCSK9), represents a significant advancement in the treatment of hypercholesterolemia. Unlike current PCSK9 inhibitors, which are injectable monoclonal antibodies and siRNA molecules, MK-0616 offers a patient-friendly alternative. The development of MK-0616 involved innovative synthetic chemistry and in vitro mRNA display technology. This cutting-edge approach led to the creation of an orally administered peptide with the ability to cover a larger portion of PCSK9 compared to smaller, linear peptides. Phase 1 and 2b clinical trials have demonstrated MK-0616’s safety, efficacy, and pharmacokinetics. These trials indicate the drug’s dose-dependent systemic absorption and long half-life. Notably, MK-0616 has exhibited comparable low-density lipoprotein cholesterol-lowering effects to currently available PCSK9 inhibitors, all while maintaining good tolerability in diverse patient populations, including those concurrently on statin therapy. As MK-0616 advances to Phase 3 trials, its lipid-lowering potential for heterozygous familial hypercholesterolemia and its impact on reducing the time to adverse cardiac events will be evaluated in a broad and diverse population, including underrepresented groups. The results achieved so far are promising for individuals with hypercholesterolemia, as they offer a potential solution for effectively lowering low-density lipoprotein cholesterol in patients on statin therapy and mitigating the risk of cardiovascular events. Ongoing research and monitoring will be critical to establish its long-term safety and efficacy, but MK-0616 may emerge as a valuable addition to the array of lipid-lowering therapies available to patients.
