简要总结
This was a Phase 1, randomized, double-blind, placebo-controlled, single ascending dose study to evaluate the safety, tolerability, pharmacokinetics (PK), and pharmacodynamics (PD) of subcutaneously administered SRSD107 in Chinese healthy subjects. SRSD107 is a synthetic, chemically modified double-stranded siRNA designed to silence hepatic FXI mRNA, thereby modulating coagulation.

- •In good health, determined by no clinically significant findings from medical history, physical examination, clinical laboratory evaluations, 12 lead ECG, and vital signs measurements, at screening and check in, as assessed by the investigator (or designee).
- •Activated partial thromboplastin time and prothrombin time within the normal reference range.
- •Females will not be pregnant or lactating, and females of childbearing potential and males will agree to use contraception as pre-defined in the protocol.

- •Any major surgery within 3 months prior to screening or plan to have any surgery during the study.
- •History of clinically significant hypersensitivity, intolerance, or allergy to any drug compound, oligonucleotide, GalNAc, food, or other substance, as determined by the investigator (or designee).
- •Systolic blood pressure >140 mmHg or <90 mmHg, or diastolic blood pressure >90 mmHg or <50 mmHg confirmed by repeat measurement.
- •QT interval corrected for heart rate using Fridericia's method (QTcF) >450 ms confirmed by repeat measurement.
- •Platelet count or hemoglobin level below the lower limit of normal.
- •Alanine aminotransferase, aspartate aminotransferase, gamma glutamyl transferase, alkaline phosphatase, or total bilirubin >1.5 × the upper limit of normal.
- •Estimated glomerular filtration rate <80 mL/min/1.73 square meter, as calculated by the 2021 Chronic Kidney Disease Epidemiology Collaboration equation.
- •Positive hepatitis B and C, positive human immunodeficiency virus test or positive syphilis test. Subjects whose results are compatible with prior immunization may be included.
- •Positive pregnancy test at screening or check in.
- •Women who are menstruating at dosing, and women whose past volume of menstrual fluid was >80 mL or menstrual periods were >7 days.
- •Use or intend to use any of the following, as determined by the investigator (or designee): 1) prescription medications/products or herbal products within 14 days or 5 terminal elimination half lives, whichever is longer, prior to dose administration in this study; 2) over the counter medications/products within 7 days prior to dose administration in this study. Recommended doses of vitamin and mineral supplements, over the counter analgesics (eg, paracetamol or ibuprofen for the treatment of acute conditions [eg, headache]), prescription oral, implantable, transdermal, injectable, or intrauterine contraceptives, and other products that have been approved by the investigator will not be exclusionary. Hormone replacement therapy will not be exclusionary, providing that the regimen has been stable for at least 2 months prior to screening and will not be changed during the study.
- •Immunization with any live vaccine within 6 weeks prior to screening, or expected to require immunization with any live vaccine during the study.
- •Receipt of an investigational drug in the past 90 days or 5 half lives of that drug, whichever is longer, prior to dosing in this study.
- •Receipt of any siRNA treatment within 12 months or any antisense oligonucleotide treatment within 6 months prior to dosing in this study.
- •Have previously completed or withdrawn from this study or any other study investigating SRSD107 and have previously received SRSD

- •Regular alcohol consumption of >21 units per week for males and >14 units for females within 12 months prior to screening. One unit of alcohol equals 375 mL of beer or lager (3.5%), 100 mL of wine (13.5%), or 30 mL of spirits (40%).
- •Use of tobacco or nicotine containing products within 1 months prior to screening.
- •Receipt of blood products within 3 months prior to check in.
- •Loss of >500 mL whole blood or donation of >200 mL blood products within 1 month prior to screening.
- •History of intolerance to subcutaneous injections, or scarring (eg, from surgical procedures or burns) in areas when subcutaneous dose administration may occur.
- •Poor peripheral venous access.
- •Subjects who, in the opinion of the investigator (or designee), should not participate in this study.
