The Safety, Tolerability, Pharmacokinetics, and Preliminary Efficacy of Injectable SPN01 in Phase I.

The Phase I Single-center, Single-blind, Randomized Clinical Study of the Safety, Tolerability, Pharmacokinetics, and Preliminary Efficacy of Injectable SPN01

The primary objective of this study is: to evaluate the safety and tolerability of injectable SPN01 in subjects. The secondary objective of this study is: to evaluate the pharmacokinetic characteristics of injectable SPN01 in subjects.The exploratory objectives of this study are: (1)to evaluate the preliminary efficacy of injectable SPN01 in subjects with colorectal cancer. (2) to evaluate the effect of the blood concentration of injectable SPN01 on the QTc interval. (3) to evaluate the metabolic characteristics of injectable SPN01 in humans.

2. Pregnancy or Donation Plans: Subjects planning to become pregnant or donate sperm/eggs during the study or within 3 months after administration.
3. Allergy to SPN01: Known allergy to any component of the investigational drug SPN01, or a history of severe allergies.
4. History of Severe Systemic Diseases: A history of serious systemic diseases (including cardiovascular, digestive, urinary, respiratory, endocrine, immune, hematological, lymphatic, musculoskeletal, neurological diseases), liver or kidney dysfunction, or psychiatric disorders.
5. Alcohol or Drug Abuse: A history of alcohol or drug abuse/dependence.
6. Severe or Uncontrolled Psychiatric Disorder: Subjects with severe or uncontrolled psychiatric diseases.
7. Active Infection: Any active infection requiring systemic treatment or uncontrolled infection within 14 days prior to the start of the study drug.
8. Infectious Disease Positive: Subjects who test positive for human immunodeficiency virus (HIV), hepatitis C virus (HCV), or syphilis; subjects who test positive for hepatitis B virus (HBV) surface antigen.
9. Needle Phobia: Subjects with a history of vasovagal response to blood draws or injections and those who cannot tolerate intravenous cannulation.
10. Blood Donation or Blood Loss: Subjects who have donated blood or experienced total blood loss of ≥400 mL within the last 3 months.
11. Medication Use: Subjects who have taken any prescription drugs, over-the-counter medications, or herbal products within 2 weeks prior to the first dose, especially those who have used antacids (e.g., proton pump inhibitors, H2 receptor antagonists), P-glycoprotein (P-gp) inhibitors, or drugs associated with a risk of torsades de pointes, or those who have used any medications within 30 days prior to the first dose that inhibit or induce liver drug metabolism.
12. Other Clinical Trials: Participation in another clinical trial and use of other investigational drugs within 30 days prior to screening.
13. Vaccination: Receipt of any vaccination within 3 months prior to screening or plans to receive a vaccine during the study.
14. Other Conditions: Any other condition that, in the opinion of the investigator, would make the subject unsuitable for participation in the clinical trial.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Safety and Tolerability	Safety and tolerability will be assessed through the monitoring of adverse events (AEs), clinical laboratory tests (including complete blood count, blood biochemistry, coagulation function, and urinalysis), local safety assessments, vital sign checks (including temperature, respiration rate, pulse rate, and blood pressure), 12-lead electrocardiogram (ECG), and physical examinations. Adverse events (AEs) and serious adverse events (SAEs) will be evaluated according to the National Cancer Institute's Common Terminology Criteria for Adverse Events (NCI-CTCAE), version 5.0. All adverse events occurring during the clinical trial will be recorded, including their clinical manifestations, severity, onset and resolution times, management measures, and outcomes. The correlation between AEs and the investigational drug will also be determined.	Predose and up to 24 hours postdose
