The Efficacy and Safety of Four Novel PCSK9 Monoclonal Antibodies in Patients With Hypercholesterolemia: A Systematic Review With Network Meta‐Analysis and Trial Sequential Analysis

Aim: This network meta-analysis (NMA) evaluated four novel proprotein convertase subtilisin/kexin type 9 (PCSK9) monoclonal antibodies for hypercholesterolemia management, comparing their lipid-lowering efficacy and safety. Methods: -scores ranked therapeutic hierarchies, with meta-regression and subgroup analyses exploring heterogeneity. Trial sequential analysis determined the adequacy of cumulative evidence. Confidence in the network meta-analysis approach was used to evaluate the confidence in the findings from NMA. Results: A total of eight trials with 3,975 Chinese patients were included. Ongericimab 150 mg every 2 weeks (Q2W) ranked first in all efficacy outcomes, demonstrating pronounced effects in LDL-C, ApoB, and Lp(a) reduction versus placebo, with mean differences of -74.21% (95% confidence interval [CI]: -79.69% to -68.73%), -64.36% (95% CI: -68.58% to -60.13%), and -50.93% (95% CI: -56.24% to -45.61%), respectively. All interventions exhibited safety profiles comparable with placebo, with no significant differences in TEAEs or serious TEAEs incidence. The analyses suggested that a portion of the evidence base was robust and reliable. Conclusion: These findings positioned ongericimab 150 mg Q2W as a clinically optimal PCSK9 inhibitor with robust lipid-lowering capacity. The results highlight the potential of next-generation PCSK9 monoclonal antibodies, particularly in East Asian populations, while underscoring the need for large-scale multinational trials to validate ethnic-specific responses.
