Clinical Trial Summary

This study evaluates the safety and efficacy of using the Hemolung RAS to provide low-flow extracorporeal carbon dioxide removal (ECCO2R) as an alternative or adjunct to invasive mechanical ventilation for patients who require respiratory support due to an acute exacerbation of Chronic Obstructive Pulmonary Disease (COPD). It is hypothesized that the Hemolung RAS can be safely used to avoid or reduce time on invasive mechanical ventilation compared to COPD patients treated with standard-of-care mechanical ventilation alone. Eligible patients will be randomized to receive lung support with either the Hemolung RAS plus standard-of-care mechanical ventilation, or standard-of-care mechanical ventilation alone.

Description:

The Hemolung RAS provides low-flow ECCO2R using a single, 15.5 French dual-lumen catheter inserted percutaneously in the femoral or jugular vein. Low-flow ECCO2R offers an alternative or supplement to invasive mechanical ventilation (MV) for patients suffering from acute, reversible, hypercapnic respiratory failure. In contrast to invasive MV, low-flow ECCO2R provides partial ventilatory support independently of the lungs. The rationale for this study is that low-flow ECCO2R with the Hemolung RAS can be used to provide supplemental CO2 removal in COPD patients experiencing acute hypercapnic respiratory failure to either avoid or reduce time on invasive MV. In this patient population, avoidance or reduced time on invasive MV may have significant clinical benefit in reducing the many complications associated with invasive MV. The major complication risks of low-flow ECCO2R are associated with central venous catheterization and the need for anticoagulation during treatment. This study is designed to evaluate the safety and efficacy of Hemolung RAS plus standard-of-care as compared to standard-of-care alone.

19. Terminal patients not expected to survive current hospitalization

20. Requiring continuous home ventilation via a tracheostomyy

Related Conditions & MeSH terms

• Acute Exacerbation of COPD

Intervention

Device:
• Hemolung Respiratory Assist System
Treatment with a medical device called the Hemolung RAS. The Hemolung RAS includes three components: the Hemolung Controller, the Hemolung Cartridge, and the Hemolung Catheter. The intervention is use of the Hemolung RAS to provide partial lung support for acute hypercapnic lung failure by filtering carbon dioxide from venous blood using a central venous catheter through which venous blood is pumped at flows of 350-550 milliliters per minute to and from an external circuit containing a hollow fiber membrane blood gas exchanger (with heparin-coated fibers) integrated with a centrifugal pump.
• Invasive mechanical ventilation
Lung support for acute lung failure applied with a mechanical ventilation device that uses positive pressure to mechanically inflate the lungs and facilitate exhalation via an endotracheal tube or tracheotomy.
