Official title
Long-term Study of LDL-c Lowering With Evolocumab: Observational Follow-up After the FOURIER OUTCOMES Trial.
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
This observational study will follow participants who completed follow-up in the FOURIER OUTCOMES trial to evaluate the long-term effects of evolocumab treatment. Long-term post-trial (legacy) beneficial effects have been reported with statins, niacin, hypoglycemic therapy and fibrates. Whether similar effects are seen after LDL cholesterol (LDL-c) lowering by PCSK9 inhibition is currently unknown. Evolocumab therapy causes a profound reduction in LDL cholesterol of approximately 60%. Statins have shown legacy effects over 5 years post-trial, including a 7% reduction in total mortality in meta-analysis and 12% reduction in coronary mortality. It would therefore be hypothesized that additional effects beyond the trial period would be conferred by previous evolocumab treatment. It is also important to assess the long-term safety of prior evolocumab treatment.
