E.2.1 | Main objective of the trial |
To evaluate the effect of MDCO-216 treatment on the change in PAV of a target coronary artery, as measured by IVUS imaging, following MDCO-216 compared with placebo in subjects with CAD and a recent ACS event in order to establish safety and the dose and regimen for Phase III clinical trials. |

E.2.2 | Secondary objectives of the trial |
To evaluate the effect of MDCO-216 on the following additional atheroma parameters measured by IVUS:
- Change in TAV from baseline to Day 36 post randomization
- Change in TAV in the 10 mm subsegment with the greatest disease burden at baseline
- Proportion of subjects who demonstrate regression of coronary atherosclerosis, defined as reduction in PAV from baseline to Day 36 of more than 2 standard deviations (SD) of the test/re-test variability.
- Proportion of subjects who demonstrate regression of coronary atherosclerosis, defined as a change in PAV from baseline to Day 36 of less than zero (ie, any reduction in PAV from baseline) |

E.3 | Principal inclusion criteria |
1.Male or female subjects greater than or equal to 18 years of age
2.Have experienced a recent ACS event within 14 days of randomization that requires a clinically indicated coronary angiogram
3.A qualifying ACS event is defined as a spontaneous MI:
A diagnosis of a qualifying MI event will be defined by abnormal levels of cardiac biomarkers (troponin I or T or creatinine kinase-myocardial isoenzyme band [CK-MB] mass) with at least one determination greater than the 99th percentile or upper limits of normal for the laboratory and at least one of the following:
•Chest discomfort or symptoms of myocardial ischemia (greater than or equal to 10 minutes) at rest within 24 hours prior to hospitalization for MI
•New electrocardiogram (ECG) findings (or presumed new if no prior ECG available) indicative of acute myocardial ischemia in absence of left ventricular hypertrophy and left bundle branch block (LBBB) as listed:
-New or presumed new ST depression greater than 0.5 millimeters (mm) in two contiguous leads or T-wave inversion greater than 1 mm in leads with predominant R wave or R/S greater than 1mm in two contiguous leads
-New or presumed new ST elevation at the J point in ≥2 contiguous leads with the cut-off points: ≥0.2 mV in men or ≥0.15mV in women in leads V2-V3 and/or ≥0.1 mV in other leads or new or presumed new LBBB
-New tall R wave >40 ms in V1, V2 and R/S ≥1 in V1 with concordant positive T-wave in the absence of a conduction defect
-New Q waves ≥30 ms wide and >1mm deep in any 2 leads of a contiguous lead grouping or Q wave >20 ms or QS complex in leads V2 and V3 (These criteria also apply to silent MI detected during a routine follow-up visit)
•Loss of viable myocardium based on imaging evidence of new or presumed new wall motion or perfusion deficit (eg, echocardiography, left ventriculography during cardiac catheterization radionuclide angiography, single-photon emission tomography, magnetic resonance imaging)
4.Baseline coronary angiogram must meet all of the following criteria for IVUS interrogation of Target Artery:
TARGET ARTERY:
•Must be accessible to the IVUS catheter
•Must have a stenotic area of ≥20% and <50% in lumen diameter by angiographic visual estimation within the length of the native coronary artery (“target segment”) for imaging by IVUS
•The target artery has not undergone prior percutaneous coronary intervention (PCI) or coronary artery bypass graft surgery (CABG)
•The target artery is not currently a candidate for intervention or a likely candidate for intervention over the treatment phase of the study and until the second IVUS interrogation at Day 36
•The target artery may not be a bypass graft
•The target artery may not be the culprit vessel for a previous MI TARGET ARTERY MAY HAVE:
•A lesion of up to 60% stenosis, distal to the target segment, provided that this area is not a target for PCI or CABG
•A single branch of the “target vessel” may have a narrowing less than or equal to 70% by visual estimation, provided that the branch in question is not a target for PCI or CABG
5.Willing and able to give informed consent before initiation of any study-related procedures and willing to comply with all required study procedures
|
|
E.4 | Principal exclusion criteria |
1.Baseline IVUS not completed due to non-qualifying coronary angiogram as demonstrated by:

•Extensive CAD with no target vessel for IVUS interrogation
2.Baseline IVUS interrogation determined to be unacceptable by the Atherosclerosis Imaging Core Laboratory
3.Clinically significant heart disease which, in the opinion of the investigator, is likely to require CABG, PCI, cardiac transplantation, and surgical or percutaneous valve repair and/or replacement following index IVUS imaging (does not apply to PCI that occurs as a result of initial screening angiogram and completed prior to index IVUS imaging)
4.New York Heart Association class III or IV heart failure or last known left ventricular ejection fraction less than 30%
5.Coronary artery bypass surgery less than 6 weeks prior to the qualifying IVUS

10.Fasting triglyceride value less than 400 mg/deciliter (dL)
11.Impaired kidney function defined as calculated glomerular filtration rate less than 60 milliliter (mL)/min by Modification of Diet in Renal Disease formula. In addition, subjects with a 0.3 mg/dL or 25% increase in serum creatinine in the initial 3 to 5 days from presentation for ACS will be excluded from the study
12.Serious comorbid disease in which the life expectancy of the subject is shorter than the duration of the trial (eg, acute systemic infection, cancer, or other serious illnesses). This includes all cancers with the exception of treated basal-cell carcinoma occurring greater than 3 years before screening
13.Body weight greater than 120 kg or less than 20 kg
14.Women who are pregnant or nursing, or who are of childbearing potential and unwilling to use at least 2 methods of contraception (oral contraceptives, barrier methods, approved contraceptive implant, long- term injectable contraception, intrauterine device or tubal ligation). Women who are greater than 2 years postmenopausal (defined as greater than or equal to 1 year since last menstrual period) AND if less than 55 years old with a negative pregnancy test within 24 hours of randomization or surgically sterile are exempt from this exclusion
15.Men who are unwilling to use an acceptable method of birth control during the entire study period (ie, condom with spermicide)
16.Previous participation in this study or any preceding study with ETC-216, MDCO-216, or similar investigational medicines containing apolipoprotein A-I (ApoA-I) proteins
17.Known allergy to the phospholipid or any other component of the investigational product (dimeric rApoA-IM, 1-Palmitoyl-2-oleoyl-sn-glycero-3-phosphocholine, or mannitol and sucrose in phosphate buffer).

•Inappropriate for this study, including subjects who are unable to communicate or to cooperate with the investigator.
•Unable to understand the protocol requirements, instructions and study-related restrictions, the nature, scope, and possible consequences of the study (including subjects whose cooperation is doubtful due to drug abuse or alcohol dependency)
•Unlikely to comply with the protocol requirements, instructions and study-related restrictions; eg, uncooperative attitude, inability to return for follow-up visits, and improbability of completing the study
•Having any medical or surgical condition, which in the opinion of the investigator, would put the subject at increased risk from participating in the study
•Subject is involved or a relative of someone directly involved in the conduct of the study
