Conditions

Acute Myocardial Infarction

Brief summary

This study is a first-in-human assessment of safety of using UCMSC in patients with AMI via a combination of IC and IV stem cell administration. The novelty of the current UMSC01 treatment study is the dual route of administration. Since dual administration of UCMSC via IC and IV had never been conducted in humans, there may be unknown risks to humans not predicted from the preclinical studies. However, the risk to patients in this trial will be minimized by rigorous adherence to the eligibility criteria, use of appropriate dose and concentration of stem cells, standardized techniques of stem cell infusion, and intensive patient monitoring during and after stem cell infusion.

Detailed description

Cardiovascular disease is the leading cause of death in the developed world, with global deaths due to coronary artery disease estimated to increase from 7.3 million in 2008 to 25 million by 2020 WHO, 2011. The leading symptom that initiates the diagnostic and therapeutic cascade in patients with suspected acute coronary syndromes (ACS) is chest pain. Most patients will ultimately develop an ST elevation myocardial infarction (STEMI). The mainstay of treatment in these patients is immediate reperfusion by primary angioplasty or fibrinolytic therapy. Basically, STEMI comprises approximately 25% to 40% of myocardial infarction (MI) presentations. Acute STEMI is a major cause of morbidity, mortality, and disability. This product is a new cell therapy product for treating AMI and produced by Ever Supreme Bio Technology Co., Ltd in Taiwan. For animal studies, UMSC01 has been demonstrated its effectiveness for AMI and stroke. The rats with coronary artery ligation receiving intravenous injection of UMSC01 showed significantly improved cardiac function.

Interventions

UMSC01 cells will be one single IC infusion followed by one single IV infusion with 12 months of follow up after treatment.

Exclusion criteria

1. Pregnant women who have clinically severe and/or life-threatening disease(s) such as uncontrolled diabetes mellitus (fasting sugar level \> 250 mg/dL) and malignant tumor. 2. Pregnant women who have been tested positive for the following tests within 7 days before or after umbilical cord acquirement: * Human immunodeficiency virus-1 (HIV-I): anti-HIV-I and nucleic acid test (NAT) * HIV-II * Hepatitis B virus (HBV): Hepatitis B surface antigen (HBsAg), anti- Hepatitis B core (HBc) and NAT * Hepatitis C virus (HCV): anti-HCV and NAT * Cytomegalovirus (CMV) (Note: If the pre-screened CMV result shows positive 8 weeks prior to umbilical cord acquirement will also be excluded.) * Treponema pallidum * Chlamydia trachomatis * Neisseria gonorrhea * Human T cell leukemia virus-I/II (HTLV-I/II) * West Nile virus (WNV) NAT 3. Pregnant women are with increased risk for Creutzfeldt-Jakob disease (CJD) if you have received a non-synthetic dura mater transplant, human pituitary-derived growth hormone, or have one or more blood relatives diagnosed with CJD. 4. Pregnant women had spent three months or more cumulatively in the United Kingdom from the beginning of 1980 through the end of 1996; or had received any transfusion of blood or blood components in the U.K. or France between 1980 and the present; or lived 5 years or more cumulatively in Europe. 5. Pregnant women or her sexual partners were born or lived in certain countries in Africa (Cameroon, Central African Republic, Chad, Congo, Equatorial Guinea, Gabon, Niger, or Nigeria) after 1977 (risk factor for HIV group O). 6. Pregnant women who have medical diagnosis of Zika virus (ZIKV) infection or residence in, or travel to, an area with active ZIKV transmission (according to the list from Centers for Disease Control and Prevention. Zika Virus: Areas with Zika.) at any point during that pregnancy. 7. Pregnant women who have sex at any point during that pregnancy with a male who is known to medical diagnosis of ZIKV infection or residence in, or travel to, an area with active ZIKV transmission. 8. Pregnant women who have received blood infusion or stayed for more than 3 months in WNV potential countries. 9. Pregnant women who have unexplained post-donation febrile illness with headache or other symptoms suggestive of WNV infection (i.e., flu-like symptoms that include fever with headache, eye pain, body aches, generalized weakness, new skin rash or swollen lymph nodes or other evidence of WNV infection) within two weeks. 10. Pregnant women who have medical history of tuberculosis. 11. Pregnant women who have medical history of malignant tumor. 12. Fetuses that have found with genetic disease in prenatal checkups. 13. Pregnant women who would like to store cord blood or umbilical cord cells, other than this study usage. 14. Pregnant women who are not suitable to donate as judged by the Investigator(s). Subject-Inclusion Criteria: 1. Male or female patients are aged ≥20, \<76 years old on date of consent. 2.
