E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The main objective of the trial is to evaluate the impact of Bendavia on limiting the size of infarcted myocardium in patients with first time anterior wall ST-segment elevation myocardial infarction (STEMI) who have undergone successful reperfusion using primary percutaneous coronary intervention (PCI) and stenting. |
|
E.2.2 | Secondary objectives of the trial |
The secondary objectives of the trial are to evaluate the impact Bendavia has in patients with acute, anterior wall STEMI on the following outcomes:
• Microvascular dysfunction
• The pharmacokinetics of Bendavia
• Renal dysfunction through 30 days and 6 months post-PCI and stenting
• Cardiac function through day 30+7 post-PCI
• The incidence of immediate myocardial complications during the primary hospitalization
• Biomarkers of congestive heart failure and systemic inflammation through 6 months
• Long-term clinical outcome at 30+7 days and 6 months
• To evaluate the safety and tolerability of a single intravenous infusion of Bendavia |
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
• Age ≥18 and <85 years of age
• The patient presents with first-time acute, anterior wall STEMI scheduled to undergo primary PCI and stenting
• The patient has symptoms of cardiac ischemia of ≥10 minutes
• The patient must demonstrate an anterior wall STEMI with >0.1 mV ST-segment elevation in at least two contiguous precordial leads (i.e., V1-V4) or presumed new left bundle branch block
• The time from onset of symptoms of cardiac ischemia to the anticipated time of initial PCI balloon inflation does not exceed four (4) hours and it is anticipated that the door-to-balloon time will be <2 hours
• For female patients of child-bearing potential, an adequate form of contraception must be adhered to prior to entry into the study and for a further 3 months after the follow-up visit. Adequate contraception is defined as the usage by the female patient of any form of hormonal contraception or intra-uterine device (which should be established prior to the start of the study) plus usage by one of the partners of an additional spermicide-containing barrier method of contraception. The use of a barrier method alone or reliance on abstinence is not considered adequate. Female patients of childbearing potential must have a negative serum pregnancy test prior to entry into the study.
• Female patients not of childbearing potential (i.e. female patients who are postmenopausal at least 12 months since last regular menses, or have been surgically sterilized) are eligible to enter the study
• For male patients with female partners of child-bearing potential, an adequate form of contraception must be adhered to prior to entry into the study and for a further 3 months after the post-study medical. Adequate contraception is defined as the usage by the female partner of any form of hormonal contraception or intra-uterine device (which should be established prior to the start of the study) plus usage by one of the partners of an additional spermicide-containing barrier method of contraception. The use of a barrier method alone or reliance on abstinence is not considered adequate.
• Written informed consent obtained that strictly adheres to the written guidelines from the local Institutional Review Board (IRB)/ Ethical Committee (EC)

E.4 | Principal exclusion criteria |
• Cardiogenic shock or maximal systolic blood pressure (BP) <80 mm Hg after fluid and/or vasopressor resuscitation on at least two consecutive readings
• Ongoing vasopressor support
• Uncontrolled hypertension defined as a systolic BP >180 mm Hg or a diastolic BP >110 mm Hg on at least two consecutive readings
• Cardiac arrest or arrhythmia requiring prolonged (>5 minutes) chest compressions/ cardiopulmonary resuscitation (CPR)
• Prior coronary artery bypass graft surgery (CABG)
• Prior myocardial infarction (MI)
• Implantable cardioverter-defibrillator (ICD) or permanent pacemaker (PPM) unless known to be MRI safe. The presence of an MRI-compatible pacemaker or other MRI-compatible hardware will not be a contraindication to participation in the trial.
• Known left ventricular ejection fraction <30% prior to the qualifying infarct
• History of clinically significant hepatic disturbance or chronic renal impairment at the time of admission
• Cerebrovascular accident (CVA) or transient ischemic attack (TIA) within the last 30 days
• Any known disorder that is associated with immunologic dysfunction (e.g., cancer, lymphoma, a positive serologic test for the human immunodeficiency virus, or hepatitis) more recently than 6 months before presentation or the administration of immunosuppressive drugs within 10 days of the STEMI at doses expected to be associated with immunosuppression including high dose steroids (>2.5 mg/d hydrocortisone or equal potency of synthetic steroids), TNF-α blockers or methotrexate/azathioprine.
• Any condition that, in the Investigator’s opinion, would prevent adherence to the requirements of the protocol including language barrier or current alcohol or drug abuse
• Contraindications (including claustrophobia) to cardiac MRI at study entry
• Participation in an investigational drug or device study within the 30 days prior to enrollment into the EMBRACE-STEMI Trial or anticipated within the next 4 days
• Female patients who are pregnant or breastfeeding during the study or intend to within 30 days of receiving study drug |

E.5 End points |
E.5.1 | Primary end point(s) |
The primary endpoint is the comparison between treatment groups of the area under the creatine kinase-MB (CK-MB) enzyme curve obtained over the initial 72 hours following the initial PCI procedure. |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
Throughout the duration of the study |
|
E.5.2 | Secondary end point(s) |
The secondary endpoints will include the following:
• Comparison between treatment groups of the area under the troponin I enzyme curve obtained over the initial 72 hours following the PCI procedure
• Comparison between treatment groups of the infarct size as measured by the volume of infarcted myocardium on the day 4±1 cardiac MRI
• Comparison between treatment groups of the infarct size as measured by the ratio of the volume of infarcted myocardium to the volume of edematous myocardium on the day 4±1 cardiac MRI
• Comparison between treatment groups of the day 4±1 and 30+7 myocardial structure and function on cardiac MRI
• Comparison between treatment groups of the incidence of immediate myocardial complications
• Calculation of the pharmacokinetic profile of Bendavia.
• Comparison between treatment groups of the myocardial infarct size on day 30+7
• Comparison between treatment groups of the laboratory markers for congestive heart failure and systemic inflammation over time
• Comparison between treatment groups of the 30+7-day and 6-month incidence of the composite endpoint
