Evolocumab or Normal Strategies to Reach LDL Objectives in Acute Myocardial Infarction Upbound to PCI
Condition(s) studied
STEMI - ST Elevation Myocardial InfarctionNSTEMI - Non-ST Segment Elevation MI
Investigational drug(s) / intervention(s)
Evolocumab 140 MG/ML: Evolocumab (Repatha®) 140 mg every two weeks: first subcutaneous injection at the time of randomization, before PCI, followings during 36 months.
Standard of care (SOC): management as recommended in ESC/EAS 2019 guidelines, within reimbursement criteria
Study summary
AMUNDSEN-real is a phase IV, international (7 European countries), multicenter, controlled, open label study randomized, in 2 parallel groups of patients with a diagnosis of STEMI or NSTEMI with an indication for PCI, using the PROBE study design (Prospective Randomised Open, Blinded Endpoint).
The objective of this study is to demonstrate the superiority of evolocumab versus standard of care in reaching a LDL-C reduction of ≥ 50% from baseline and a LDL-C goal of \<1.4 mmol/L (\<55 mg/dL) at 12 months follow-up on the overall population.
The primary clinical objective is to demonstrate the superiority of evolocumab versus standard of care on the composite endpoint of death or any unplanned hospitalization for a CV reason at 12 months.
Central randomization uses an IWRS. Stratification is by center and stratum with random block size, generated according to the procedures of the sponsor, by a statistician not involved in the study.
Eligibility
Inclusion Criteria:
Participant meeting all of the following criteria will be considered for enrolment into the trial:
1. Diagnosis of STEMI or NSTEMI
STEMI defined as:
* symptoms of acute MI of at least 30 min AND
* within the previous 24 hours with new persistent ST-segment elevation ≥1 mm in ≥2 continuous ECG leads AND
* an indication for primary PCI AND
* \> 55 years reported by the patient
NSTEMI defined as:
* Age≥18
* a history of chest discomfort or ischemic symptoms of ≥10 minutes duration at rest ≤48 hours prior to entry into the trial with no evidence of persistent ST-segment elevation and with an elevated troponin (≥ the upper limit of normal according to local laboratory norms), AND
* indication for a coronary angiogram within 72hrs AND
* indication for PCI AND
* at least one the following high-risk characteristics: Diabetes Peripheral Artery Disease Multivessel (≥ 2 or LM) disease on the coronary angiogram History of MI or stroke without sequels prior to randomization eGFR: 15 to 45 mL/min/1.73 m2 calculated with MDRD formula at randomization
2. Statin at maximal tolerated dose, as part of the standard of care at randomization, means Intent to treat with statin and the patient will receive his first dose as soon as possible after admission
3. Informed consent obtained in writing at enrolment into the trial
Exclusion Criteria:
Participant presenting with any of the following will not be included in the trial:
1. Fibrinolysis treatment
2. Planned CABG
3. Ongoing hemodynamic instability defined as any of the following:
* Killip Class III or IV
* Sustained and/or symptomatic hypotension (systolic blood pressure \< 80 mm Hg)
* Known left ventricular ejection fraction \< 30%
4. Evidence of severe hepatobiliary disease: current active hepatic dysfunction or active biliary obstruction, decompensated cirrhosis or infectious/inflammatory hepatitis
5. Active malignancy
6. A comorbid condition with an estimated life expectancy of ≤ 12 months
7. Previously received or receiving evolocumab or any other therapy to inhibit PCSK9
8. Known sensitivity to any of the products or components to be administered during trial
9. Female subject is pregnant, had a positive pregnancy test at inclusion, breastfeeding, or planning to become pregnant or breastfeed during treatment and for an additional 17 weeks after the last dose of IMP
10. Currently receiving treatment in any other investigational device or drug trial, or less than 30 days since ending treatment on another investigational device or drug trial.
11. Participant likely to not be available to complete all protocol-required trial visits or procedures, and/or to comply with all required trial procedures to the best of the participant and investigator's knowledge.
Primary outcome measure(s)
- LDL-C reduction of ≥ 50% from baseline and a final LDL-C of <1.4 mmol/L (<55 mg/dL) at 12 months follow-up — From baseline and at 12 months
Monitoring of changes in LDL-C levels
- Composite endpoint of death (any cause) or any unplanned hospitalization for a CV reason — Frome randomization to 12 months follow-up
Main clinical endpoint obtained from reported adverse events occurred during participation to the study
