A Research Study to Evaluate the Safety and Tolerability of SGC001 in Healthy Subjects

A Randomized, Double-Blind, Placebo-Controlled, Single Ascending Dose Phase Ia Clinical Study to Evaluate the Safety, Tolerability, Pharmacokinetic Profile, Pharmacodynamics Profile, and Immunogenicity of SGC001 in Healthy Adult Subjects

Acute Myocardial Infarction (AMI) is an acute ischemic necrosis that occurs following acute stenosis or occlusion of the coronary arteries, and it is associated with a high morbidity and mortality rate. Acute myocardial infarction typically occurs in middle-aged and elderly individuals, according to the American Heart Association, with the average age of first occurrence being 65.1 years for men and 72.0 years for women. Myocardial infarction (MI) has a significant impact on global health, affecting over 7 million people worldwide annually. In addition, MI can impose a substantial economic burden on society and families. The research study is a Randomized, Double-Blind, Placebo-Controlled, Single Ascending Dose Phase Ia Clinical Study to Evaluate the Safety, Tolerability, Pharmacokinetic Profile, Pharmacodynamics Profile, and Immunogenicity of SGC001 in Healthy Adult Subjects

In addition, they must agree to refrain from collecting or donating eggs during this period; their male partner of childbearing potential must also agree to use effective contraception during this period.
5. Male subjects of childbearing potential must agree to use effective contraception and have no plans to conceive or donate sperm from screening until 3 months after receiving the investigational drug. During this period, their female partner of childbearing potential must also agree to use effective contraception.

8. Individuals who have smoked within 3 months before screening (consuming ≥ 5 cigarettes per day) or habitual use of nicotine containing products.
9. Individuals who have consumed more than 14 units of alcohol per week (1 unit of alcohol = 360 mL of beer or 45 mL of spirits with 40% of alcohol content or 150 mL of wine) within 3 months prior to screening, or who consume alcohol-containing products within 48 hours before dosing, or who have a positive alcohol breath test result at screening and/or D-1.
10. Individuals who have received monoclonal antibody or biologic therapy within 3 months prior to receiving the investigational drug.
11. Individuals who have received medications that may affect the immune system (e.g., immunosuppressants, cytokines and cytokine inducers,) within 3 months prior to receiving the investigational drug.
12. Individuals who have received anticoagulant or antiplatelet medications within 28 days prior to receiving the investigational drug.
13. Individuals who have received any vaccine within 28 days prior to receiving the investigational drug, or who plan to receive a vaccine during the trial period.

15. Individuals who have used any prescription drugs, over-the-counter drugs, Chinese herbal medicines, or health supplements within 14 days prior to receiving the investigational drug or within the 5 half-lives of the drug (whichever is longer).
16. Individuals whose screening viral serology tests are positive for human immunodeficiency virus antigen/antibodies (HIV-Ag/Ab), hepatitis B surface antigen (HBsAg), hepatitis C virus antibodies (HCV-Ab), or antibodies to Treponema pallidum (TP-Ab).
17. Individuals who have difficulty in venous blood collection or have a history of needle and blood fainting.
18. Women who have positive result in pregnancy test or are breastfeeding at Screening or D-1.
19. Individuals who have participated in other drug clinical studies and received other clinical trial drugs within 3 months prior to receiving the investigational drug.
20. Individuals who have history of blood donation or massive blood loss (≥ 400 mL) within 3 months prior to screening.
21. Any other circumstance that, in the judgement of the investigator, may affect the ability of the subject to provide informed consent or to follow the trial protocol, or where the subject's participation in the trial may affect the outcome of the trial or his/her safety.
