ARDS defined by: - acute respiratory failure on invasive or non invasive ventilation - bilateral pulmonary infiltrates on the chest X-ray, with a picture compatible with a pulmonary edema - Pa02/FI02 ratio of less than or equal to 200 mm Hg - no sign of left atrial hypertension (congestive heart failure)
Persistence defined by: - Pa02/FI02 ratio of less than or equal to 200 mm Hg under invasive ventilation, with a PEEP level of higher than or equal to 5 cm H2O, 12 to 24 hours after the ARDS criteria were met (under invasive mechanical ventilation), as defined by the French Conference Consensus
B) Predicted body weight less than or equal to 90 kg : predicted body weight of male patients is calculated as equal to 50 + 0.91 (cms of height – 152.4); that of female patients as equal to 45.5 + 0.91 (cms of height – 152.4) |

E.4 | Principal exclusion criteria |
- positive pregnancy test in woman of childbearing potential - patients suffering from pulmonary emphysema before ARDS occurred, with a TLC value higher than 130 % predicted - patients suffering from pulmonary fibrosis before ARDS occurred, with a TLC value less than or equal to 70 % predicted - patients with ARDS secondary to traumatism - patients suffering from ALI with a Pa02/FI02 ratio of less than or equal to 300 mm Hg under non invasive or invasive ventilation, for more than 24 hours before ARDS criteria were met - patients who are moribund and not expected to survive for more than 72 hours - patients suffering from a lung pneumocystosis - patients with a bronchopleural fistula - patients having received a systemic corticosteroid treatment at a dose higher than or equal to 0.5 mg/kg prednisolone for more than 2 weeks before inclusion - patients whose family or physician are not committed to aggressive support for more than 72 hours - patients with Pa02/FI02 less than or equal to 80 mm Hg, whatever the level of PEEP, contraindicating the BAL - patients with severe organ diseases : (a) renal failure : specific renal SOFA score = 4 or under dialysis (b) cardiovascular failure : severe hemodynamic instability graded III by Jardin score, with persistent of metabolic acidosis, defined as a base deficit of > 5 mmol/L present for > 6 hours, despite administration of vasoactive drugs (c) hepatic failure: specific hepatic SOFA score = 4 or Child-Pugh score class C (d)neutropenia: blood neutrophil count < 1000/mm3, or neutropenia expected because of ongoing cytostatic treatment (e) patients having received a bone marrow transplantation - patients already included in another therapeutical trial |

E.5 End points |
E.5.1 | Primary end point(s) |
A) Safety criteria - Incidence of adverse events - Change in vital signs - Change in safety blood chemistry and haematology parameters from "pre-treatment" to "during treatment" at 96 ± 24 hours, after initiation of infusion, to "post-treatment" at 48 ± 24 hours after the end of infusion, and to Day 28 or ICU discharge - Incidence of nosocomial infections during the study period from Day 1 to Day 28 - Incidence of barotraumatisms (pneumothorax) during the period of mechanical ventilation - Evolution of organs failure assessed by global and specific SOFA scores change from "pre-treatment" to "during treatment", and from "pre-treatment" to "post treatment", and from "pre-treatment" to Day 28 or ICU discharge - Anti-Depelestat antibodies plasma levels from "pre-treatment" to "post treatment" and to Day 28 or ICU discharge
