Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
The current standard of care (SOC) for treatment of patients with acute respiratory distress syndrome (ARDS), inhalation injury, volume overload, and/or pulmonary dysfunction is mechanical ventilation (MV). However, these techniques are associated with several complications after prolonged use, including risk of infection, increased sedation requirements, pulmonary edema, ventilator-induced lung injury (VILI), barotrauma, and multi-organ failure.
Extracorporeal life support (ECLS) has been used to successfully minimize, replace, or avoid the use of MV. This concept is critical as it permits ultra-lung protective MV settings, mobilization, early ambulation of patients, and timely extubation (when appropriate).
Conventional ECLS typically requires blood flows of 3-6 L/min, and its cannula sizes range from 21-25 Fr. This is by definition "high-flow" as it constitutes near-complete extracorporeal circulation of patient's circulating blood volume. On the other hand, low-flow ECLS at 1-2.5 L/min has been shown to prevent deleterious shifts in pH and PaCO2 at a lower level of invasiveness, and its cannula sizes range from 19-20 Fr dual lumen cannulas (which are associated with less serial dilation). The investigators propose the use of a low-flow circuit to include the NovaLung system in conjunction with a smaller tubing set and cannula to enable earlier utilization of ECLS with less invasiveness and smaller catheters. Specifically, the study will either utilize the Crescent RA cannula (or equivalent dual-lumen cannula) or use a 15-25 Fr cannula, both with 3/8 tubing/step-down tubing, as needed, for our study. A femoral (fem)-femoral or femoral-internal jugular (IJ) approach may also be used.
Carbon dioxide is six times more diffusible than oxygen across the membrane; thus, carbon dioxide transfers can occur with high efficiency at our targeted blood flows of 1-2.5L/min. Oxygen can still transfer at these blood flows, and low flow can improve oxygen levels to some degree.
There are three benchtop-based manuscripts that suggest that low-flow ECMO is associated with a potential increase in factors that increase the risk of bleeding complications/circuit changes. However, the manuscripts either tested \<1 L/min blood flow rates, or the effect of cannula size was not considered. None of them included the biological component of endothelial interaction. Mitigating the risk of bleeding complications by will be completed by administering anticoagulants with a target PTT of 40-50 seconds, and by monitoring the patients and their coagulation panels closely. There may be less risk of circuit clotting in our study because of chosen flow rates (1-2.5 L/min).

Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
The investigators focus is to demonstrate the safety, feasibility, and efficacy of low-flow ECLS as a treatment for multiple respiratory conditions (including ARDS, volume overload, obstructive and restrictive pulmonary diseases, hypoxia) in conjunction with MV.
BACKGROUND
The two most significant trials in the last five years investigating strategies around low-flow ECLS with the intent of CO2 reduction/ventilator reduction are as follows:
* SUPERNOVA Multi-Center Phase II Study in Europe and Canada: In 2019 Combes et al assessed the feasibility and safety of lower CO2 extraction ECLS devices (300-500 mL/min) in patients with moderate ARDS compared to higher CO2 extraction ECLS devices (800-1000 mL/min, N=95). The authors concluded that the use of low-flow ECLS to facilitate ultra-protective ventilation was feasible, and that it mitigated respiratory acidosis in patients with moderate ARDS.
* REST Multi-Center Randomized Clinical Trial (RCT) in the United Kingdom: In 2021 McNamee et al set to determine whether lower tidal volume MV using extracorporeal CO2 removal improves outcomes in adult patients with acute hypoxemia respiratory failure (n=202) compared to conventional low tidal volume MV (n=210). There were significantly fewer mean ventilator-free days in the extracorporeal CO2 removal group compared with the SOC (p=0.02). However, the trial was halted because of futility and feasibility. Although the conclusion was that the use of extracorporeal CO2 removal did not significantly reduce 90-day mortality (p=0.68), the study may have been underpowered to detect an important difference. Furthermore, the most notable limitation of the study was that the duration of low-flow ECLS was limited to less than 7 days (which caused discontinuation of the intervention in 33 patients). The authors state that "it is possible that a longer duration of ECCO2R with greater tidal volume reduction may have been required to demonstrate an effect because higher intensities of invasive MV have been shown to be associated with increased risk of death in a time-dependent fashion". Additional limitations of the study were that (1) only 6% of the screened patients were included in the study, (2) 8% of the randomized subjects in the intervention group did not receive the intervention, and (3) most of the sites had not performed ECLS before the initiation of the study, leading to practical inexperience potentially negatively influencing the outcomes of the intervention group.
The investigators note several differences in their protocol that differentiates it from the REST trial. First, the investigators will use a device capable of obtaining higher blood flow rates with higher initial targets of blood flow (1-2.5L/minute). Specifically, the study will use a low-flow circuit to include the NovaLung system (Fresenius Medical Care, Waltham MA) in conjunction with a smaller tubing set and cannula (15 - 25 Fr versus 23 - 31 for conventional ECMO, as needed) to enable earlier utilization of ECLS with less invasiveness and smaller catheters. Second, the current study includes broader limitations to length of time of the device (e.g. 28 days versus 7 days), which may be a more pragmatic and generalizable approach.

However, these techniques are associated with several complications after prolonged use, including risk of infection, increased sedation requirements, pulmonary edema, ventilator-induced lung injury (VILI), barotrauma, and multi-organ failure.

This concept is critical as it permits ultra-lung protective MV settings, mobilization, early ambulation of patients, and timely extubation (when appropriate).
Low-flow ECLS has been shown to prevent deleterious shifts in pH and PaCO2 at a lower level of invasiveness. The investigators hypothesize that the use of low-flow ECLS will be a safe option for the treatment of pulmonary dysfunction and mild and moderate ARDS, that it will significantly reduce MV settings, and that it will decrease the need for intubation for patients requiring respiratory support for either failure to oxygenate or ventilate.
PROCEDURES Subjects meeting criteria for enrollment will be screened by the Principal Investigator or any delegates assigned to review the patient's chart. A HIPAA authorization and informed consent will be provided by the subject or legally authorized representative (LAR) prior to conducting any additional research procedures.
Patients enrolled after consent is obtained will be placed on Low-Flow ECMO by trained physicians. Subjects will be cannulated in one of two ways, either at bedside with the use of radiographic imaging to confirm accurate cannula placement, or in the catheter laboratory under fluoroscopy with safety measures in place to appropriately monitor the patient's vital signs, ventilatory measurements, and LF ECMO settings.
Initiation of LF ECMO will require cannula placement and connection to the Novalung XLung extracorporeal circuit. Size and type of cannula will be determined by the investigator and documented at cannulation. The XLung will be used with circuit to accommodate lower flows necessary to efficiently move 1-2.5 LPM of blood through the oxygenator. Subjects treated with low-flow ECMO will receive systemic anticoagulation per standard of care for patients treated with ECLS. After cannulation and placement on LF ECMO, blood gases will be drawn from the patient, pre-Xlung, and post-Xlung to assess the function of the Novalung system, patient's stability after initiation, and the ability to effectively wean ventilatory support.
Multiple labs will be collected and documented as routine standard of care while others will be collected prior to device implementation and during the duration of therapy for research purposes. The following is considered standard of care (as needed, daily): arterial blood gases, lactate, platelet count. Standard of care costs are billed to insurance. The following are considered research costs (prior to device initiation, within one hour of device initiation \[if collected\]): arterial blood gases, lactate, platelet count. Heparin doses, aPTT, ACT, anti-Xa, plasma-free hemoglobin, pre- and post-membrane analyses are all research costs, in addition to inflammatory markers and functional outcomes (6MWT, quality of life questionnaires). All research costs are covered by the awarded grant.
Biospecimens: Approximately 2 mLs of blood will be collected in tubes containing EDTA at least seven times (pre-ECLS, daily, post-ECLS, discharge, 30-, 60-, 90-days post-discharge, as available). Blood will be taken prior to the administration of anesthesia (when applicable), from an existing catheter, or by venipuncture. The samples will be placed on ice, and blood will be separated by centrifugation within 30 minutes of collection to yield roughly 1 mL of plasma. The samples will be stored in appropriate freezer (long-term of ≤-80ºC or temporarily ≤-20°C). Urine (up to 10 mLs) will be collected either from the subject's urinary retention catheter or directly from the subject in a urine cup, and it will be stored in appropriate freezer (long-term of ≤ -80ºC or temporarily ≤ -20°C) until analysis.
