SUPERNOVA: A Strategy of UltraProtective lung ventilation  With Extracorporeal CO2 Removal for New-Onset moderate to seVere ARDS



ARDSnet strategy might not protect against tidal hyperinflation

  • When Pplat remains >28-30 cm H2O

Further decrease of Vt

  • From 6 to 5, 4 or 3 ml/kg IBW
  • To decrease Pplat <25 cm H2O, To decrease delta P
  • To further reduce VILI
  • With sufficient PEEP to prevent lung derecruitment

Induced hypercapnia controlled by extracorporeal CO2 removal

  • “CO2 dialysis”
  • Low-flow devices

PILOT trial

Feasibility and safety
100 patients
Starting date: Autumn 2015


The aim is to randomise up to 1500 patients
There will be an adaptive design
The protocol will be finalised according to the results of the pilot trial

Study Objectives

Extracorporeal CO2(ECCO2R) removal devices (PALP, MAQUET; ILA-active, NOVALUNG; Hemolung, ALung) allowVT and plateau pressure reduction in patients with moderate ARDS. This study will assess changes in pH/ PaO2 /PaCO2, Respiratory Rate and device CO2 clearance in the first 24 hours of ECCO2R following VT and plateau pressure reduction in patients with moderate ARDS. Safety variables during treatment will also be analysed.

Research protocol

  • Study design: We plan to prospectively collect data on 100 patients during usual care in 21 centers.
  • Study devices: PALP, MAQUET; ILA-active, NOVALUNG; Hemolung, ALung. All devices are CE-marked in the European Union.

How do I participate?

A selection of ICUs will take part in the pilot study (approx. 20)
