Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The current study aims to evaluate different doses of PC-SOD injections for efficacy and safety in comparison to placebo, in order to provide a basis for future clinical trials in terms of experimental design and dose selection.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The study is a randomized, single-blind, multi-center, placebo-controlled trial to preliminarily evaluate the efficacy and safety of PC-SOD, and to provide a basis for dose selection in the next stage of study.

For each participant, the trial will be divided into the screening/treatment (screening and treatment conducted during the first visit, 0 d) and safety follow-up (1 - 30 d) stages.

The study will screen 120 eligible subjects. After successful screening, the subjects will be randomly assigned into four groups of equal size, including the 40 mg PC-SOD, 80 mg PC-SOD, 160 mg PC-SOD and placebo control groups. Subjects in each group will be administered the corresponding intervention, followed by PCI treatment. During the safety follow-up stage, the subjects will receive basic treatment based on Guidelines for Management of Patients with ST-segment elevation myocardial infarction. Treatments will include dual anti-platelet therapy, beta-blockers, ACEI/ARB (angiotensin-converting enzyme inhibitor/ angiotensin receptor blocker), statins, anticoagulants, and so on.

By comparing the efficacy and safety endpoints of patients in the experimental and placebo control groups, the study aims to preliminarily evaluate the efficacy and safety of different doses of PC-SOD in reducing myocardial reperfusion injury.

Blinding Strategy

SINGLE

Participants
Since the appearance of PC-SOD preparations cannot be identical to that of placebo, and treatment groups have different administration doses, the study will be conducted in a single-blind manner, where only subjects (and families) are blinded and do not know whether they are treated by PC-SOD or placebo before unblinding.

Interpretation of cardiac MRI and ECG will also be conducted in a blinding manner. Images of all subjects will be evaluated blindly by researchers not directly involved in the study.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

3. Killip classes I or II;
4. Coronary angiography possible within 6 hours of onset;
5. Emergent coronary angiography showing occlusion in left anterior descending artery (TIMI grade 0 - 1); patients with this symptom could also be included despite inconformity to criterion 2);
6. Willingness to participate in the trial with ethical approval and informed consent provision.

Exclusion Criteria

1. Previous history of myocardial infarction;
2. History of myocardial revascularization before screening;
3. Thrombolytic treatment after onset;
4. Cardiogenic shock;
5. Cardiopulmonary resuscitation between onset and screening;
6. Atrial fibrillation, atrioventricular block (degree I, II or III), and other severe arrhythmias that cannot be corrected and affect hemodynamics;
7. Suspected of aortic dissection;
8. Diabetes with long-term insulin use, or definite macrovascular or small vascular lesions (stroke, diabetic nephropathy, retinopathy, diabetic foot, and etc.);
9. History of major surgeries within 6 months;
10. History of stroke within 6 months;
11. History of immune disorders within 6 months (such as cancer, lymphoma, HIV or hepatitis), or use of immunosuppressive agents at doses that can cause immunosuppression within 10 days;
12. Clinically significant diseases of the respiratory, digestive, blood, immune, endocrine, nervous or urinary systems (renal insufficiency in particular), and diseases that might cause serious risk to patients based on the judgement of researchers;
13. Allergy to two or more drugs and/or foods, or known allergy to sucrose;
14. Any contraindications for cardiac MRI, such as implantation of metal objects (pacemakers and/or implantable defibrillators; insulin pumps, or any other electronic devices; cerebral clips, aneurysm clips, and etc.), and other contraindications (such as claustrophobia);
15. Pregnancy or lactation in women;
16. Participation in other clinical trials within 3 months;
17. Situations considered unsuitable for enrollment (such as disease condition or patient compliance).


1. Occlusion of left main artery;
2. Apart from the left anterior descending branch, other blood vessels requiring revascularization in the same period or within a month.
