Brief Summary:
This clinical study was designed to assess the efficacy, safety, and tolerability of long-term dosing of inclisiran and evolocumab given as subcutaneous injections in participants with high cardiovascular risk and elevated low-density lipoprotein cholesterol (LDL-C).
| Condition or disease | Intervention/treatment | Phase |
|---|---|---|
| Atherosclerotic Cardiovascular Disease Symptomatic Atherosclerosis Type2 Diabetes Familial Hypercholesterolemia | Drug: Inclisiran Drug: Evolocumab | Phase 2 |
MDCO-PCS-16-01 (ORION-3) was a Phase II, open-label, multicenter, non-randomized, active comparator long term extension study. Total study duration was 4 years from first participant enrolled to the last subject completed. The study consisted of three study periods:
Screening Period: Participants completing study MDCO-PCS-15-01 (ORION-1) were screened for all inclusion and exclusion criteria of study ORION-3.
Treatment Period: Participants fulfilling all eligibility criteria of ORION-3 were enrolled. Participants who received inclisiran in ORION-1 received inclisiran sodium throughout this study up to 4 years (Group 1; Inclisiran-only arm), and participants who received placebo in ORION-1 received evolocumab as open-label comparator up to Day 336, and then transitioned to inclisiran on Day 360 and every 180 days thereafter for up to 4 years (Group 2; Switching arm).
Safety follow up: Participants were followed up for safety during 4 weeks after the last dose of study treatment. Including the Screening Period, the total study duration for a participant was up to 4 years.

- Unable to understand the protocol requirements, instructions and study-related restrictions, the nature, scope, and possible consequences of the study (including participants whose cooperation is doubtful due to drug abuse or alcohol dependency).
- Unlikely to comply with the protocol requirements, instructions, and study-related restrictions (for example, uncooperative attitude, inability to return for follow-up visits, and improbability of completing the study).
