TORONTO, ON / ACCESSWIRE / July 30, 2020 / Edesa Biotech, Inc. (NASDAQ:EDSA), a clinical-stage biopharmaceutical company, has filed an investigational new drug (IND) application with the U.S. Food and Drug Administration (FDA) for the initiation of a Phase 2/Phase 3 clinical study of its investigational drug, EB05, for the treatment of hospitalized COVID-19 patients. The company recently received expedited approval to begin the Phase 2/3 study in Canada and is seeking government grants to accelerate site selection and initiate patient enrollment.
EB05 is an experimental monoclonal antibody that the company believes could regulate the overactive immune response associated with Acute Respiratory Distress Syndrome (ARDS) - the leading cause of death in COVID-19 patients. Specifically, the drug inhibits toll-like receptor 4 (TLR4) signaling - an important mediator of inflammation responsible for acute lung injury that has been shown to be activated by SARS-CoV1 and Influenza viruses.
Based on previous clinical data and the mechanism of action, the company believes that modulating the TLR4 signaling pathway could reduce the number of ICU patients and decrease the need for mechanical ventilation, ultimately saving lives. The safety and tolerability of EB05 has been demonstrated in more than 120 subjects. The antibody therapy has demonstrated an ability to resolve fever as well as stabilize heart rates and breathing rates in test subjects who were injected with a potent inducer of acute systemic inflammation.
"The submission of the IND for EB05 in COVID-19 patients marks a key step in our plans to extend our planned Phase 2/3 study," said Dr. Par Nijhawan, Chief Executive Officer of Edesa. "We have received positive interest from key opinion leaders regarding our proposed clinical trial and are communicating with hospitals across the country regarding our protocol."
As planned, Edesa's Phase 2/3 study will be an adaptive, multicenter, randomized, double-blind, placebo-controlled study to evaluate the efficacy and safety of EB05 in adult hospitalized patients who have or are at risk of developing ARDS. The company plans to enroll up to 450 patients in the first phase of the trial. Patients will be infused intravenously with a single dose of EB05 or placebo. Should the drug treatment demonstrate promising results at the Phase 2 readout, the protocol allows for enrollment to continue as a pivotal Phase 3 study. The newly filed IND application for the COVID-19 study supplements and references an existing approved IND for EB05.
Acute Respiratory Distress Syndrome is the leading cause of death in COVID-19 patients. The U.S. Centers for Disease Control (CDC) reports that 20% to 42% of hospitalized COVID-19 patients develop ARDS, which increases to 67% to 85% for patients admitted to the ICU. Mortality among patients admitted to the ICU ranges from 39% to 72% depending on the study and characteristics of patient population, according to the CDC. ARDS involves an exaggerated immune response leading to inflammation and injury to the lungs that results in edema that deprives the body of oxygen. For moderate to severe cases, there are currently few meaningful treatments, other than supplemental oxygen and mechanical ventilation, and patients suffer high mortality rates. In addition to virus-induced pneumonia, ARDS can be caused by smoke/chemical inhalation, sepsis, chest injury and other causes. Prior to COVID-19, ARDS accounted for 10% of intensive care unit admissions, representing more than 3 million patients globally each year. ARDS has historically affected approximately 200,000 patients each year in the United States, resulting in nearly 75,000 deaths annually.
