About this trial
The main objective is to compare the effect of a single injection of two doses of rituximab versus placebo on 6 months left ventricular systolic function, using CMR, in patients who have had an acute anterior STEMI. Following the sponsor's decision to stop enrolment in the 200 mg arm, the primary objective of the study is to evaluate the efficacy of a single 1000 mg dose of rituximab versus placebo.
The primary endpoint is the left ventricular ejection fraction (LVEF) by CMR at 6 months.
Eligibility criteria
Qualifiers
Age ≥ 18 years with no upper limit (women must be either postmenopausal defined as being amenorrhoeic for greater than 2 years with an appropriate clinical profile, e.g. age appropriate (>55 years old), history of vasomotor symptoms) or having documented hysterectomy and/or bilateral oophorectomy) ;
Clinical evidence at presentation of anterior ST-elevation myocardial infarction (STEMI) defined as symptoms suggestive of acute myocardial ischemia, an electrocardiogram showing ST-segment elevation ≥2 mm in ≥2 contiguous leads in V1 to V4;
Complete occlusion (i.e. TIMI flow 0-1) of proximal or mid left anterior descending (LAD) coronary artery on urgent angiography interpreted as the infarct-related artery (IRA);
Onset of worse symptoms within 48 hours before primary PCI;
Disqualifiers
History of previous MI;
Presentation with cardiac arrest;
Cardiogenic shock (defined as systolic blood pressure <90 mmHg for >30minutes, or necessitating vasopressors to achieve a blood pressure ≥90 mmHg);
Cardiac electrical instability (defined as complete heart block needing temporary pacing or any tachyarrhythmia needing cardioversion);
