TORONTO, ON / ACCESSWIRE / October 25, 2023 / Edesa Biotech, Inc. (Nasdaq:EDSA), a clinical-stage biopharmaceutical company focused on inflammatory and immune-related diseases, today announced that Health Canada has approved the company's proposal to harmonize clinical trial designs in the U.S. and Canada for an ongoing Phase 3 study of EB05 (paridiprubart). Edesa's monoclonal antibody is currently being evaluated as a treatment for Acute Respiratory Distress Syndrome (ARDS), a life-threatening form of respiratory failure characterized by widespread inflammatory injury to the lungs. Approximately 10% of all ICU admissions are ARDS related.
The harmonized protocol calls for treatment of approximately 600 ARDS subjects hospitalized with SARS-CoV2 infections who are on invasive mechanical ventilation, both with and without additional organ support such as extracorporeal membrane oxygenation (ECMO). The primary endpoint is the mortality rate at 28 days. The amended study design replaces the previous protocol which targeted a population of more than 800 subjects, with two independent cohorts and cohort-specific endpoints. Earlier this year, Edesa and the U.S. Food and Drug Administration agreed on the primary efficacy endpoint and single, smaller population for the Phase 3 study.
Par Nijhawan, MD, Chief Executive Officer of Edesa Biotech said that having a single, harmonized protocol in the U.S. and Canada will facilitate enrollment, trial management and data analysis.
"We are pleased that regulators have agreed to our plans to optimize the study population and other protocol updates. We believe that aligning our efforts across the U.S. and Canada will streamline the development of EB05 and ultimately deliver a first-in-class therapy for critically ill ARDS patients who today continue to suffer from high rates of morbidity and mortality," said Dr. Nijhawan.
Paridiprubart is a first-in-class monoclonal antibody developed for acute and chronic disease indications that involve dysregulated innate immune responses. This host-directed therapeutic (HDT) candidate inhibits toll-like receptor 4 (TLR4), a key immune signaling protein that has been shown to be activated both by viruses, like SARS-CoV2 and influenza, as well as in the pathogenesis of chronic autoimmune diseases. In a Phase 2 clinical study that the company completed during the pandemic EB05 (paridiprubart) reduced mortality by 84% among critically ill patients with ARDS. A parallel in vitro study also demonstrated that paridiprubart inhibits inflammation from influenza and other pathogens.
Dr. Nijhawan said that the company is also exploring various approaches to evaluate EB05 in a general, all-cause ARDS population.
About ARDS
ARDS involves an exaggerated immune response leading to inflammation and injury to the lungs that prevents the lungs from oxygenating blood and ultimately 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 the pandemic, ARDS accounted for 10% of intensive care unit admissions, representing more than 3 million patients globally each year.
About Edesa Biotech, Inc.
Edesa Biotech, Inc. (Nasdaq:EDSA) is a clinical-stage biopharmaceutical company developing innovative ways to treat inflammatory and immune-related diseases. The company's most advanced drug candidate is EB05 (paridiprubart), a monoclonal antibody developed for acute and chronic disease indications that involve dysregulated innate immune responses. Edesa is currently evaluating EB05 in a Phase 3 study as a potential treatment for Acute Respiratory Distress Syndrome (ARDS), a life-threatening form of respiratory failure. In addition, Edesa is developing an sPLA2 inhibitor, EB01 (daniluromer), as a topical treatment for chronic Allergic Contact Dermatitis (ACD), a common occupational skin condition. The company has also received regulatory approval to conduct a Phase 2 trial its EB06 monoclonal antibody as a treatment for vitiligo, a life-altering autoimmune disease that causes skin to lose its color in patches. Edesa is also planning to file an investigational new drug application for a future Phase 2 study of paridiprubart for systemic sclerosis (scleroderma), an autoimmune rheumatic disorder that causes fibrosis, (scarring/hardening) of skin and internal organs.
