Serious Adverse Events of Inclisiran in Patients With Hypercholesterolemia, a Meta-Analysis of ORION Trials

Several studies have been conducted over the years to find an effective and safe therapeutic agent to treat hypercholesterolemia. Inclisiran is a novel drug being studied for its efficacy and safety in reducing LDL-C levels in patients to reduce the risk of cardiovascular diseases. No previous study was done to review the trials for the serious adverse events for this drug. The primary objective of this research is to investigate the incidence of serious adverse events of this drug.A systematic review and meta analysis of clinical trials is performed.A systematic search of PubMed, Embase and ClinicalTrials.gov , from their inception till July 3, 2023 , was performed for ORION Trials studying the efficacy and safety of Inclisiran. The random-effects model was used in the meta-analysis to provide a pooled proportion of serious adverse events. Risk of bias of each study was assessed by the Cochrane Risk of Bias Tool.From 319 studies searched from the databases, only 8 relevant articles remained after a detailed evaluation. These studies, having a total of 4981 patients, were involved in the analysis with a pooled estimate showing a non-significant incidence of serious adverse events. Each adverse event was studied individually and Product issues and Endocrine disorders had the highest Odds ratio among them. All included studies were classified as moderate quality.Following systematic review and meta-analysis, we found no significant differences in any serious adverse events following administration of Inclisiran.However, larger ongoing trials will provide additional data to evaluate the safety profile of this agent.
