Novel Approaches to Acute and Chronic Conditions
Edesa is exploring new ways to treat inflammatory and autoimmune diseases, including innovative alternatives to topical steroids, which can have serious side-effects.
Clinical Pipeline Status
As of March 2021
Our current clinical studies are designed to further evaluate safety and efficacy. Since many of these drug candidates come to us with well characterized efficacy and safety data, we avoid much of the lengthy process of preclinical R&D studies and advance to meaningful data readouts more quickly.
Allergic Contact Dermatitis
. The Platform
EB01 is a novel sPLA2 inhibitor for the topical treatment of chronic Allergic Contact Dermatitis (ACD). EB01 employs a novel mechanism of action and in two clinical studies has demonstrated statistically significant improvement of multiple symptoms in contact dermatitis patients.
Contact dermatitis is one of the most common occupational health illnesses in the United States, and has been estimated to cost approximately $2 billion annually. We estimate that there are more than 13.2 million people in the United States with contact dermatitis, with between 20% and 60% of all cases of contact dermatitis diagnosed as ACD. We believe EB01 will primarily benefit those who have chronic ACD.
Edesa is conducting a double-blind, dose-ranging vehicle-controlled adaptive design clinical trial to evaluate the safety and efficacy of EB01 in a population with moderate to severe allergic contact dermatitis. The first cohort was fully enrolled as of March 2021.
Immunotherapy – Monoclonal antibody
Vitiligo is a life-altering autoimmune disease that results in the depigmenting of the skin. People who have vitiligo develop white patches of skin due to the destruction of special cells called melanocytes which produce the skin pigment melanin. The cause of vitiligo is not known but evidence strongly suggests that vitiligo is an autoimmune disorder in which the body’s immune system mistakenly targets and injures these cells. Vitiligo can affect any area of skin, but it commonly occurs on the face, neck and hands. According to the World Health Organization, vitiligo affects approximately 1% of the world’s population. It is a lifelong condition.
Despite high prevalence, vitiligo remains one of the most untouched areas in modern medical treatments and there has been little research compared to other immune disorders. Currently there are few treatment options available for patients with limited efficacy.
We are working with the National Research Council of Canada (NRC) to develop novel immunotherapies for vitiligo as well as other indications. NRC scientists will produce multiple monoclonal antibodies for Edesa to identify a lead candidate to take into IND-enabling studies.
Additional Dermatological Indications
sPLA2 Inhibitor and Others
Edesa also intends to expand the utility of its sPLA2 inhibitor technology across multiple indications.
EB02 is a novel sPLA2 inhibitor for the treatment of hemorrhoids.
Hemorrhoids affect ~12.5 million adults in the US. Each year 3 million prescriptions are written in the U.S. for hemorrhoids, in addition to 22 million over the counter units. Current treatments entered the market prior to 1962 and provide only temporary relief from symptoms.
Health Canada has approved Edesa’s CTA for a proof-of-concept study.
Acute Respiratory Distress Syndrome
Monoclonal antibodies (mAbs)
EB05 and EB06
EB05 and EB06 are mAbs targeting TLR4 and the chemokine CXCL10, respectively.
Acute respiratory distress syndrome (ARDS) is a life-threatening form of respiratory failure, and the leading cause of death among COVID-19 patients. 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.
Due to the global health crisis, Edesa has prioritized the evaluation of EB05 as a potential treatment for hospitalized COVID-19 patients. Patient enrollment for the EB05 study is ongoing in the U.S., Canada and Colombia.
We believe that targeting the sPLA2 enzyme family with enzyme inhibitors will have a superior therapeutic effect because the inflammatory process will be inhibited at its inception rather than after inflammation has occurred.
