Brief Summary

This is a randomized, double-blind, placebo-controlled Phase II clinical study of TISA-818-Inj in patients with ARDS to evaluate the safety, preliminary efficacy, and population PK (Pop PK) profile of TISA-818-Inj in adult ARDS patients. Totally 60 subjects with ARDS are planned to be included in this study. Subjects will be assigned to the 6 mg twice daily (BID) TISA-818-Inj group, 12 mg once daily (QD) TISA-818-Inj group, or the placebo control group in a 1:1:1 ratio using a stratified block randomization method. This study includes a screening period (Day -3 to Day -1), a treatment period (Day 1 to Day 14),a short-term follow-up period (Day 15 to Day 60) and a long-term follow-up period (Day 61 to Day 180). Consenting subjects will be screened for eligibility, according to study-specific inclusion/exclusion criteria.

• C-reactive protein (CRP) level is higher than the upper limit of normal (ULN) value;
• Be able to receive the investigational drug within 72 hours after the first diagnosis of the ARDS;
• Men and women of childbearing potential (women of childbearing potential include premenopausal women and those within 2 years of menopause) who are willing to use highly effective contraception (condom, contraceptive sponge, gel, film, intrauterine device, oral or injected contraceptives, subcutaneous implants, etc.) from signing the informed consent form through 6 months after the last dose of the investigational drug.

You may not qualify if:

• Be allergic to the test drug or excipients;
• Have an expected survival of ≤ 72 hours as judged by the investigator;
• Have other current or previous serious pulmonary disease at screening, including but not limited to WHO Class III or IV pulmonary hypertension, chronic lung disease requiring long-term oxygen therapy, or previous lung transplantation;
• Have a current or previous active cardiovascular disease at screening, including but not limited to Chronic heart disease (New York Heart Association functional class IV), episodes of cardiac arrest or acute myocardial infarction within 4 weeks before screening;
• Severe hemodynamic instability at screening (defined as norepinephrine dose \> 0.5 μg/kg/min or dopamine dose \> 20 μg/kg/min);
• Chronic hemodialysis and known severe renal impairment (creatinine clearance rate\<30 mL/min, appendix 8);
• The following laboratory abnormal values exist:
• Bone marrow function: platelet count \<30 × 109/L, hemoglobin\<7.0 g/dL;
• Liver function: aspartate aminotransferase (AST) or alanine aminotransferase (ALT) \>3 times the ULN value and serum bilirubin (T-Bil) \>2 times the ULN,;
