Lead Sponsor

Brief Summary

This phase IIb, randomized, placebo-controlled, double-blind, dose escalation study will assess the local and systemic safety of 7 days orally inhaled sequential multiple ascending doses of solnatide in patients with pulmonary permeability oedema and moderate-to-severe ARDS and review potential efficacy endpoints for a future phase III pivotal trial.

Inclusion Criteria
  1. Informed consent

  2. Male or female ≥18 years of age.

  3. Patient has been admitted to an ICU, is mechanically ventilated (according to the ventilation and weaning protocol in Appendix I) and stable in this condition for at least 8 hours.

  4. Moderate-to-severe ARDS diagnosis as defined by the Berlin Definition:

    • Onset of ARDS within 1 week of a known clinical insult or new or worsening respiratory symptoms.
    • Bilateral opacities not fully explained by effusions, lobar/lung collapse, or nodules.
    • Respiratory failure not fully explained by cardiac failure or fluid overload (origin of oedema).
    • PaO2/FiO2 ≤ 200 mm Hg with Positive End-Expiratory Pressure (PEEP) ≥5 cm H2O.
  5. ARDS diagnosis not older than 48 hours.

  6. Extravascular lung water index (EVLWI) ≥ 10 ml/PBW as assessed with a validated bedside measurement (single indicator transpulmonary thermodilution measurement with the PiCCO® system).

  7. Patient who meets criteria for extensive hemodynamic monitoring as per international intensive care medicine standards.

  8. For patients that are temporarily unable to consent (e.g. comatose patients) a subsequent informed consent has to be provided.

  9. Male and Female (WOCBP) patients using adequate contraception.

Exclusion Criteria
  1. History of clinically relevant allergies or idiosyncrasies to solnatide.
  2. Known use of any other investigational or non-registered drug within 30 days prior to study enrolment.
  3. Severe state of septic shock with a Mean Arterial Pressure (MAP) ≤ 65 mm Hg and a serum lactate level > 4 mmol/L (36 mg/dL) despite adequate volume resuscitation.
  4. An underlying clinical condition that, in the opinion of the Investigator, would make it very unlikely for the patient to be successfully weaned from ventilation due to severe underlying diseases (e.g. severe malnutrition, severe neurological diseases, pulmonary fibrosis or COPD).
  5. Extra-corporeal membrane oxygenation, high-frequency oscillatory ventilation or any form of extra-corporeal lung support. In no way are patients to be denied or delayed these procedures to avoid exclusion from the study.
  6. Neutrophil count < 0.3 x 109/L.
  7. Cancer treatment (chemotherapy or biological) or therapy with other immunosuppressive agents for organ transplantation within 2 weeks.
  8. Cachexia (BMI < 18.5 kg/m2).
  9. Cardiogenic pulmonary oedema diagnosed by echocardiography or pulmonary artery catheter.
  10. Severe skin burns involving more than 15% of body surface.
  11. Subjects who are extremely unlikely to survive more than 48 hours due to the acute conditions of the patient in the opinion of the Investigator.
  12. Subjects transferred from a hospital not participating in this study who are already planned to be re-transferred during the observation period.
  13. Subjects who are not expected to survive the next month because of an underlying uncorrectable medical condition or a do not resuscitate order.
  14. Women known to be pregnant, lactating or having a positive or indeterminate pregnancy test.

Primary Outcome Measures
NameTimeMethod
Safety endpoint: Any cause deathRandomisation - day 28

Primary Safety Endpoint: Composite endpoint including any cause death at day 28

Safety endpoint: Drug-related adverse eventsRandomisation - day 14

Primary Safety Endpoint: Composite endpoint including drug-related adverse events through day 14

Safety endpoint: All adverse eventsRandomisation - day 28

Primary Safety Endpoint: Composite endpoint including all adverse events through day 28

Secondary Outcome Measures
NameTimeMethod
EVLWIbaseline - day 7

Change in extravascular lung water index (EVLWI) as assessed with a validated bedside measurement (measurement with the PiCCO® system)

PVPIbaseline - day 7

Change in pulmonary vascular permeability index (PVPI) as assessed with a validated bedside measurement (measurement with the PiCCO® system)

Change of ventilatory settingsbaseline - day 14

Composite endpoint including ventilation mode, ventilation pressures (ventilatory plateau pressure, positive end expiratory pressure, peak inspiratory pressure, mean airway pressure, peak airway pressure, driving pressure), tidal volume

Murray lung injury scorebaseline - day 7

Murray lung injury score is composed of four components: 1) chest radiograph; 2) hypoxaemia score; 3) PEEP and 4) static compliance of respiratory system. The values of the total score may range from 0 to 4. Lower values indicate a better outcome.

Ventilator-free days (VFD)baseline - day 28
Days of hospitalization and in ICUbaseline - day 28
