HCR040 is an investigational medicinal product whose active substance is HC016, allogeneic adipose-derived adult mesenchymal stem cells expanded and pulsed with H2O2.~The main purpose of this study is to evaluate the safety and tolerability of a single administration of HCR040 using: a) two sequential escalating doses administered 96 hours post-injury to participants with moderate to severe acute respiratory distress syndrome (ARDS); and b) the determined maximum tolerated dose administered 96 hours post-injury to participants with moderate to severe ARDS. The study also includes initial exploration of efficacy.~Treatment is administered by intravenous injection.~The study has been divided into two phases:~Phase 1 (open label): 6 participants with moderate to severe ARDS will be included in 2 sequential cohorts.~Phase 2 (randomized, controlled, double-blind): 20 participants with moderate to severe ARDS will be randomly divided into two groups (control and treated).
The main objective of the study is to assess the feasibility, safety, and tolerability of the administration of HCR040, a drug whose active substance is HC016, allogeneic adipose-derived adult mesenchymal stem cells expanded and pulsed with H2O2, in patients with acute respiratory distress syndrome.
