Long-term Study of Inclisiran Safety and Tolerability in Young and Adult Participants with Familial Hypercholesterolemia Who Completed Pediatric ORION Studies

What this Trial Is About

Researchers are evaluating the long-term safety and tolerability of inclisiran in participants with heterozygous or homozygous familial hypercholesterolemia HeFH or HoFH. This open-label, single-arm, multicenter extension study includes participants who have completed prior pediatric ORION studies ORION-16, ORION-13, ORION-20, or ORION-19. The trial aims to provide continued access to inclisiran treatment while monitoring safety outcomes over an extended period. Participants receive inclisiran injections, with dosing based on their previous study participation and weight. Those from ORION-16 or ORION-13 receive a 300 mg dose equivalent to 284 mg inclisiran in a 1.5 mL solution. Participants from ORION-19 and ORION-20 receive weight-based dosing. The study allows ongoing treatment with inclisiran to assess long-term effects and tolerability. During the study, participants are monitored for treatment-emergent adverse events and serious adverse events from day one through up to 1080 days. Researchers also measure changes in LDL cholesterol levels from the baseline of the prior studies to the end of this extension. The involvement includes regular safety assessments and evaluations to ensure participant well-being throughout the study duration, which may last nearly three years.
