- This Phase 2 clinical study will evaluate paridiprubart (EB05) in hospitalized patients with acute respiratory distress syndrome (ARDS) due to a variety of causes.
- This BARDA-funded project is expected to complement Edesa's ongoing drug development activities in COVID-19 ARDS.
- Paridiprubart was selected following a competitive review process of multiple host-directed therapeutic candidates.
TORONTO, ON / ACCESSWIRE / June 24, 2024 / Edesa Biotech, Inc. (Nasdaq:EDSA), a clinical-stage biopharmaceutical company focused on developing host-directed therapeutics (HDTs) for immuno-inflammatory diseases, announced today that its first-in-class drug candidate has been selected by the Biomedical Advanced Research and Development Authority (BARDA), part of the Administration for Strategic Preparedness and Response within the U.S. Department of Health and Human Services, for evaluation in a U.S. government-funded clinical study.
Edesa's drug paridiprubart represents a new class of HDTs that are designed to modulate the body's own immune response when confronted with known or unknown public health threats such as pandemic influenza, COVID-19, other emerging infectious diseases, and chemical, biological, radiological, and nuclear incidents. Importantly, HDTs are agnostic to the causal agent and can be stockpiled preemptively to respond to public health emergencies and biodefense.
"HDTs have the potential to become key countermeasures for both critical care medicine as well as pandemic preparedness and biodefense, and we are pleased to be part of public-private efforts to speed the development of novel therapeutics that are threat-agnostic and can be rapidly deployed to protect civilian and military populations," said Par Nijhawan, MD, Chief Executive Officer of Edesa Biotech.
The BARDA-funded Phase 2 platform trial will be a randomized, double-blinded, placebo-controlled, multi-center U.S. clinical trial to investigate three novel threat-agnostic host-directed therapeutics, including paridiprubart, in hospitalized adult patients with ARDS. The BARDA study of paridiprubart is expected to build on the success of a Phase 2 clinical study that the company completed during the COVID-19 pandemic which demonstrated that paridiprubart reduced mortality by 84% among critically ill ARDS patients. A parallel study using an in vitro model also demonstrated that paridiprubart inhibits a key mediator of inflammatory responses from influenza and other pathogens. A separate Edesa-sponsored Phase 3 study of paridiprubart in patients with ARDS due to SARS-CoV-2 infection is currently ongoing in Canada and the U.S.
Dr. Nijhawan said that the data from the BARDA-run study, which includes an exploratory biomarker study, could provide additional support and insight for expanding the utility of paridiprubart. "We expect this parallel study to inform our development, regulatory, and commercialization plans. Our ultimate goal is to label paridiprubart as a standard-of-care drug therapy for all-cause ARDS," he said.
The BARDA-funded study will be managed under a BARDA contract with PPD Development, LP, a clinical research business of Thermo Fisher Scientific, Inc. For the paridiprubart cohort of the study, patients will be randomized one-to-one to either paridiprubart plus Standard of Care (SOC) or to a placebo plus SOC control arm. Edesa will provide drug products to the study as well as technical support. Additional details regarding this trial can be found on the BARDA website.
About ARDS
Acute Respiratory Distress Syndrome manifests in some patients as 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 recommended treatments other than supplemental oxygen and mechanical ventilation, and mortality rates are high. 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 Paridiprubart
Paridiprubart is a first-in-class human monoclonal antibody developed for acute and chronic disease indications that involve dysregulated innate immune responses. This host-directed therapeutic candidate inhibits toll-like receptor 4 (TLR4), a key immune signaling receptor that has been shown to be activated both by viruses, like SARS-CoV-2, SARS-CoV-1, and influenza, as well as in the pathogenesis of chronic autoimmune diseases.
About Edesa's Phase 3 Clinical Study
Edesa's Phase 3 study of paridiprubart is a multicenter, randomized, double-blind, placebo-controlled study to evaluate the efficacy and safety of paridiprubart in critical-care patients. The current protocol will recruit ARDS subjects hospitalized with SARS-CoV-2 infections who are on invasive mechanical ventilation, both with and without additional organ support. The primary endpoint of the trial is the mortality rate at 28 days.
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 paridiprubart (EB05), a monoclonal antibody developed for acute and chronic disease indications that involve dysregulated innate immune responses. Edesa is currently evaluating paridiprubart (EB05) in a Phase 3 study as a potential treatment for 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 of 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 (EB05) for pulmonary fibrosis. Sign up for news alerts.
