About this study
Official title: Pilot Feasibility and Safety Study on Low-flow Extracorporeal CO2 Removal in Patients With Moderate ARDS to Enhance Lung Protective Ventilation
Pathophysiological, experimental and clinical data suggest that an '"ultraprotective" mechanical ventilation strategy may further reduce VILI and ARDS-associated morbidity and mortality. Severe hypercapnia induced by VT reduction in this setting might be efficiently controlled by ECCO2R devices. A proof-of-concept study conducted on a limited number of ARDS cases indicated that ECCO2R allowing VT reduction to 3.5-5 ml/kg to achieve Pplat<25 cm H2O may further reduce VILI.
Read the detailed description
Over the past few decades, highly significant progress has been made in understanding the pathophysiology of the acute respiratory distress syndrome (ARDS). Recognition of ventilation-induced lung injuries (VILI) has led to the radical modification of the ventilatory management of these patients. The landmark trial by the ARDSnet trial group demonstrated in 2000 that ventilating ARDS patients with a low tidal volume (VT) of 6 ml/kg (calculated from predicted body weight), and with a maximum end-inspiratory plateau pressure (Pplat) of 30 cmH2O decreased mortality from 39.8% (in the conventional arm treated with a VT of 12 ml/kg PBW) to 31% . However, recent studies have shown that lung hyperinflation still occurs in approximately 30% of ARDS patients even though they are being ventilated using the ARDSNet strategy. Additionally, Hager and coworkers found that mortality decreased as Pplat declined from high to low levels at all levels of Pplat on the data collected by the "ARDSNet" trial group. Their analysis suggested a beneficial effect of VT reduction even for patients who already had Pplat<30 cm H2O before VT reduction.Similar observation was also recently reported by Needham et al on a cohort of 485 patients with ARDS. Because VT reduction to <6 ml/kg to achieve very low Pplat may induce severe hypercapnia and may cause elevated intracranial pressure, pulmonary hypertension, decreased myocardial contractility, decreased renal blood flow, and the release of endogenous catecholamines, this strategy using "ultraprotective" MV settings is not possible for most patients on conventional mechanical ventilation for moderate to severe ARDS.
Extracorporeal carbon dioxide removal (ECCO2R) may be used in association with mechanical ventilation to permit VT reduction to <6 ml/kg and to achieve very low Pplat (20-25 cm H2O). In an observational study conducted in the 80's, Gattinoni showed that use of venovenous ECCO2R at a flow of 1.5-2.5 l/min in addition to quasi apneic mechanical ventilation with peak inspiratory pressures limited to 35-45 cmH2O and PEEP set at 15-25 cmH2O resulted in lower than expected mortality in an observational cohort of severe ARDS patients. However, a randomized, controlled single-center study using that same technology and conducted in the 1990s by Morris's group in Utah was stopped early for futility after only 40 patients had been enrolled and failed to demonstrate a mortality benefit with this device (58% in the control group vs. 70% in the treatment group).
In recent years, new-generation ECCO2R devices have been developed. They offer lower resistance to blood flow, have small priming volumes and have much more effective gas exchange. With ECCO2R the patient's PaCO2 is principally determined by the rate of fresh gas flow through the membrane lung. In an ECCO2R animal model, CO2 removal averaged 72±1.2 mL/min at blood flows of 450 mL/min, while CO2 production by the lung decreased by 50% with reduction of minute ventilation from 5.6 L/min at baseline to 2.6 L/min after insertion of the device. Lastly, Terragni et al (15)demonstrated that ECCO2R could improve pulmonary protection by allowing very low tidal volume ventilation (3.5-5 ml/kg of PBW) in a proof-of-concept study of ten patients with ARDS. This strategy was also associated with a significant decrease in pulmonary inflammatory biomarkers.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
ECCO2R will be initiated during the 2-hour run-in timeDevice
A single (15.5 to 19 Fr) veno-venous ECCO2R catheter will be inserted percutaneously (jugular vein strongly suggested).
Catheters should be rinsed with heparinized saline solution before insertion Once the catheter has been inserted each line will be filled with an heparinized saline solution before its connection to the extracorporeal circuit The ECCO2R circuit will be connected to the catheter and blood flow set, depending on the device, up to 1000 mL/min.
Initially, sweep gas flow through the ECCO2R device will be set at zero (0 LPM) such as to not initiate CO2 removal through the device.
Anticoagulation will be maintained with unfractionated heparin to a target aPTT of 1.5 - 2.0X baseline. A bolus of heparin is suggested at the time of cannulation.
Neuromuscular blocking agents (NMBA)Other
Patients will receive NMBA starting in the run-in period and continued for the first 24 hours and thereafter will be directed by the attending physician
VentilationDevice
Following the 2-hour run-in time, VT will be reduced gradually to 5 mL/kg. Sweep gas initiated then VT decreased to 4.5 then 4 mL/kg and PEEP adjusted to reach 23 ≤ Pplat ≤ 25 cm H2O.
Level of carbon dioxide released at the end of expirationOther
EtCO2 will be monitored for safety purposes. Blood gases will be analyzed 20-30 minutes after each VT reduction
Respiratory RateOther
RR will be kept what it was at baseline
Sweep gas flowOther
Sweep gas flow will be adapted to maintain the same EtCO2
Ventilation will be adaptedOther
If PaCO2> 75 mmHg and/or pH < 7.2, despite respiratory rate of 35/min and optimized ECCO2R, VT will be increased to the last previously tolerated VT.
Respiratory rate will be adaptedOther
If PaCO2 remains within the target range, respiratory rate will be progressively decreased to a minimum of 15/ min and facilitated by increases in sweep flow.
| Study group | Role | What they receive |
|---|---|---|
| One single arm | Experimental | Procedure: Baseline ventilator settings will be established per the EXPRESS protocol: VT = 6 mL/kg (ideal body weight); inspiratory flow will be set at 50-70 L/min resulting in an end-inspiratory pause of 0.2-0.5 sec, I:E ratio 1:1 to 1:3, PEEP set so that the plateau pressure (Pplat), measured during the end-inspiratory pause of 0.2 to 0.5 s, will be within the following limits: 28 cm H2O ≤ Pplat ≤ 30 cm H2O; Set RR to 20-35 to maintain approximately the same minute ventilation as before study initiation. Baseline ventilator settings will be maintained for a 2-hour run-in time (time to setup ECCO2R devices). Use heated humidifiers for gas humidification and minimize instrumental dead space. ECCO2R will be initiated during the 2-hour run-in time. Neuromuscular blocking agents (NMBA) will be used. EtCO2 will be monitored. RR will be kept what it was at Baseline. Sweep gas flow will be adapted. Ventilation will be adapted. Respiratory rate will be adapted.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
Pathophysiological, experimental and clinical data suggest that an '"ultraprotective" mechanical ventilation strategy may further reduce VILI and ARDS-associated morbidity and mortality. Severe hypercapnia induced by VT reduction in this setting might be efficiently controlled by ECCO2R devices. A proof-of-concept study conducted on a limited number of ARDS cases indicated that ECCO2R allowing VT reduction to 3.5-5 ml/kg to achieve Pplat<25 cm H2O may further reduce VILI.

The record lists 1 site in Belgium. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this combined phase mean?
Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Achievement of VT reduction to 4 mL/kg while maintaining pH and PaCO2 to ± 20% of baseline values obtained at VT of 6 mL/kg. (time frame: maximum 28 days). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT02282657, which also lists 2 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 4 Aug 2017; AzTrials last refreshed its copy on 7 Nov 2026.
