ALung Technologies announced that the Food and Drug Administration (FDA) has granted the Company Emergency Use Authorization (EUA) designation to the Hemolung® Respiratory Assist System (RAS) for the treatment of Coronavirus Disease 2019 (COVID-19) patients.

ALung Technologies has treated numerous COVID-19 patients in the U.S. under existing FDA Emergency Use Provisions, and in the European Union, where the Company is approved having been granted their CE Mark in 2013.

The Hemolung® RAS is currently being used in the FDA approved VENT-AVOID trial for the study of ECCO₂R in the treatment of Acute Exacerbation of Chronic Obstructive Pulmonary Disease (AE-COPD). In addition, the Hemolung RAS and ECCO₂R have been studied for the treatment of moderate to severe Acute Respiratory Distress Syndrome (ARDS) in the just concluded UK REST trial, which enrolled 412 patients.

A public health emergency related to COVID-19 was declared by the Secretary of Health and Human Services (HHS) on February 4, 2020. The FDA has issued a EUA for the Hemolung RAS to treat lung failure caused by COVID-19. As indicated in the FDA’s EUA letter to ALung, the Hemolung RAS is not FDA-cleared or approved, and there are no FDA-approved or cleared device treatments for lung failure caused by COVID-19. ALung submitted and the FDA reviewed in vitro and in vivo information in support of ALung’s ongoing U.S. VENT-AVOID clinical trial for the Hemolung RAS as well as additional information about the clinical use of the Hemolung RAS outside the U.S., and additional biocompatibility, cytotoxicity, and performance testing.

Based on the information submitted, the FDA stated that it believes the Hemolung RAS has the potential to treat lung failure as an adjunct to noninvasive or invasive mechanical ventilation, to reduce hypercapnia and hypercapnic acidosis due to COVID-19, and/or to maintain normalized levels of partial pressure of carbon dioxide(PCO₂) and pH in patients suffering from acute, reversible respiratory failure due to COVID-19 for whom ventilation of CO₂ cannot be adequately, safely, or tolerably achieved and, in turn, may provide clinical benefit, and that there is no adequate, approved and available alternative to the emergency use of the Hemolung RAS to treat lung failure caused by COVID-19.

“We are pleased with the FDA’s recognition that the Hemolung may be beneficial in the treatment of COVID-19 by removal of CO₂ directly from the blood during extracorporeal therapy,” said Mr. Peter M. DeComo, Chairman and CEO of ALung Technologies.

Mr. DeComo further stated, “With published mortality rates as high as 90% for patients receiving invasive mechanical ventilation (IMV), we believe that the Hemolung can be a valuable tool for physicians to be used in conjunction with IMV, by reducing or eliminating the potential of further lung damage caused by high ventilator driving pressures, often referred to as Ventilator Induced Lung Injury (VILI). Many of the academic medical centers involved with our clinical trial have already requested the use of the Hemolung RAS for treatment of their COVID-19 patients.”
