Poractant Alfa (Curosurf®)) -- Effect in Adult Patients Diagnosed With 2019 Novel Coronavirus (SARS-COV-19; (Covid-19)) Acute Respiratory Distress Syndrome (ARDS)

This was a multicentre, open-label, randomized phase II proof-of-concept study.

The efficacy and safety of poractant alfa was evaluated in terms of ventilatory free days during the 21 days after randomization, in adult patients diagnosed with ARDS due to SARS-COV-19 infection.

Each patient randomized to the study treatment received 3 administrations of Curosurf ® with a 24 hours dosing interval. The assessment collection was up to Day 28, when the evaluation occurred at the Intensive Care Unit (ICU), or by phone call if the patient has already been discharged.

Seventy patients were planned to be randomized in the study with a ratio 3:2 (i.e. 42 patients in the poractant alfa arm and 28 in the control arm). The control arm population received Standard of Care (SoC). This study was conducted in United Kingdom (UK), United States of America (US), and Italy.

Overall, 13 patients (Curosurf ® group) and 8 patients (control group) were randomised in the study. Due to low recruitment rate the study was terminated early for non-safety reasons.

Curosurf® is a pulmonary surfactant of natural origin which, when delivered endotracheally (ET). Curosurf® is currently approved for marketing as treatment of premature neonates with RDS or at risk of Respiratory Distress Syndrome (RDS). Chiesi Farmaceutici S.p.A (Chiesi) conducted this study with its porcine-derived surfactant, Curosurf® (poractant alfa), to evaluate the efficacy and safety in ventilated adult patients who were critically unwell in intensive care with SARS-COV-19 ARDS.
