Clinical efficacy of invimestrocel for acute respiratory distress syndrome caused by pneumonia: Comparison with historical data using propensity score analysis

Résumé fourni par la source

Introduction: Acute respiratory distress syndrome (ARDS) is a life-threatening inflammatory lung injury often resulting from pneumonia. The efficacy and safety of invimestrocel in patients with pneumonia-induced ARDS have been demonstrated previously in a phase II randomized, open-label trial (the ONE-BRIDGE study). In this study, we aimed to compare data from the intervention (invimestrocel) arm of the ONE-BRIDGE study with matched historical data from a previously established cohort to provide further support for the beneficial effects of invimestrocel in patients with pneumonia-induced ARDS. Methods: ratio, and high-resolution computed tomography scores. The primary outcomes measured were ventilator-free days (VFDs) during the first 28 days following treatment and mortality on days 28, 60, 90, and 180. Results: Patients in the Invimestrocel group showed higher VFDs (14.8 ± 11.0 vs. 6.7 ± 9.4 days; 95 % confidence interval [CI], 1.4-14.7; p = 0.0110) and survival rates (log-rank testing; hazard ratio, 0.330; 95 % CI, 0.116-0.938) than those in the matched historical data group. Conclusions: The addition of invimestrocel to the standard treatment for pneumonia-induced ARDS may result in early withdrawal from the ventilator and lower mortality. However, further randomized, blinded, and placebo-controlled studies without or addressing multiplicity are required to confirm these findings.
