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.
