简要总结
The EARLY trial is a phase IV, investigator initiated, international, multicentre study that will investigate if early use of alirocumab 150mg plus atorvastatin 80mg (enhanced care) will have a greater effect than atorvastatin 80mg (standard care) on the reduction of LDL-C at 2-weeks after a myocardial infarction (MI), in patients who start treatment within 24 hours of symptom onset.
A secondary goal is to assess the effects of enhanced care when compared to standard care which is either atorvastatin alone or atorvastatin plus ezetimibe, (the latter added at 4 weeks if LDL-C is ≥ 70mg/dL (1.8mmol/L), on the proportion of patients achieving an LDL-C goal of < 50mg/dL (1.29 mmol/L) at 7 weeks after an MI.
详细描述
Patients with Acute Coronary Syndrome (ACS), which includes myocardial infarction, are at high risk of recurrent ischaemic events (e.g. heart attacks), and death. The current standard treatment includes high dose statins to lower low-density lipoprotein cholesterol (LDL-C), also known as bad cholesterol, soon after admission. In some cases, following assessment after 1-3 months, administration of a second line cholesterol lowering therapy (ezetimibe) may be added if LDL-C levels remain high ≥ 70mg/dL (1.8mmol/L). Many guidelines advocate that following ACS high dose statins should be used as first line therapy. If LDL-C levels remain greater than 70mg/dL (1.8mmol/L) then additional add on therapy on statins could be considered for ACS patients.
Consented patients meeting the eligibility criteria for the EARLY trial will be randomised to enhanced care or standard care within 24hrs of symptom onset for MI. Patients randomised to enhanced care will receive alirocumab 150 mg on randomisation and then every 2 weeks during a 7-week treatment period. All patients will receive atorvastatin 80 mg. Patients randomised to standard care with an LDL-C level ≥ 70mg/dL (1.8mmol/L) at week 4 will receive ezetimibe 10 mg, in addition to atorvastatin 80 mg for the remaining duration of the treatment period.
All patients will be followed up for a two-week period after completing the 7-week treatment period (i.e. a total of 9 weeks to assess safety).
