EDESA BIOTECH, INC. The double-blind, placebo-controlled trial evaluated the safety and efficacy of EB01 in approximately 200 subjects, who were treated for 28 days with either EB01 cream (2.0%, 1.0% or 0.2%) or a placebo/vehicle cream. The primary efficacy outcome measurement was the mean percent improvement in symptoms from baseline at day 29 on the Contact Dermatitis Severity Index (CDSI). A key secondary efficacy measurement was the success rate of subjects achieving a score of 'clear' or 'almost clear' with at least a 2-point improvement from baseline after treatment at day 29 on the Investigator's Static Global Assessment (ISGA) scale.
Edesa reported that 1.0% EB01 cream demonstrated statistically significant improvement over placebo. For the primary endpoint, patients with 1.0% EB01-treated lesions demonstrated a 60% average improvement in symptoms from baseline at day 29 on the CDSI versus 39% for placebo/vehicle (p=0.02). The effect was also observed at 15 days (44% for 1.0% EB01 vs 29% for placebo; p=0.05) and continued at follow-up (64% for 1.0% EB01 vs. 44% for placebo; p=0.04). For the ISGA secondary efficacy endpoint, 53% of patients with 1.0% EB01-treated lesions achieved a score of 'clear' or 'almost clear' with at least a 2-point improvement from baseline after treatment at day 29 (p=0.04). Only 29% of patients in the placebo group reached the same endpoint. No serious treatment-related adverse events were reported across all concentrations.
We are pleased that the study findings demonstrated that the 1.0% EB01 cream helped patients with moderate-to-severe disease significantly reduce their symptoms and achieve clear or almost clear skin in more than half the cases. A significant improvement was evident as early as two weeks from initiation of treatment,' said Par Nijhawan, MD, Chief Executive Officer of Edesa. 'The favorable topline results from this arm of the study underscore the potential of the drug's powerful anti-inflammatory effect and our belief that EB01 could become a standard of care treatment option for patients living with chronic allergic contact dermatitis.'
Edesa is preparing for an End of Phase 2 meeting with FDA following full analysis. The company expects to complete the analysis of the Phase 2b data by midyear.
About Allergic Contact Dermatitis
Contact dermatitis, which can be either irritant contact dermatitis or ACD (sometimes called allergic contact eczema), is one of the most common occupational health illnesses in
About
Contact Dermatitis Clinical Program
EB01, a non-steroidal anti-inflammatory compound that inhibits secretory phospholipase 2 (sPLA2) as a treatment for the symptoms of chronic allergic contact dermatitis (ACD)
EB01 is a topical vanishing cream that exerts its anti-inflammatory activity through the inhibition of sPLA2 pro-inflammatory enzymes. The sPLA2 enzyme family plays a key role in initiating inflammation associated with numerous diseases. By targeting sPLA2 with enzyme inhibitors - at the inception of inflammation rather than after inflammation has occurred - Edesa believes that drugs based on this technology could provide a powerful anti-inflammatory therapeutic strategy for treating diverse inflammatory/allergic conditions. EB01 has demonstrated efficacy for the treatment of ACD in two previous clinical trials, and has demonstrated anti-inflammatory activity in a variety of in vitro and in vivo preclinical pharmacology models.
ARDS Clinical Program
EB05, a novel monoclonal antibody targeting Toll-like Receptor 4 (TLR4) as a critical care therapy for Acute Respiratory Distress Syndrome (ARDS) - Phase 3: Enrolling
EB05 inhibits signaling through TLR4 - a key pattern recognition receptor involved in the activation of the innate immune system. Excessive TLR4 pathway activation can be pathological and has been linked to various inflammatory conditions, including viral-mediated acute lung injury.
EB05 has extensive preclinical and clinical experience, including evaluations in more than 600 hospitalized Covid-19 subjects. In an international Phase 2 study, a single dose of EB05 demonstrated compelling preliminary evidence of the drug's ability to reduce mortality in target patient populations. Among the results, critically ill hospitalized Covid-19 patients given EB05 plus standard of care treatment had an 84% reduction in the risk of dying when compared to placebo plus standard of care at 28 days.
Cautionary Note Regarding Clinical Studies
Topline results are preliminary in nature, and further analysis may result in additional, different or inconsistent findings to those described in this press release. As such, these topline or interim results should not be considered the complete, final or definitive results of the Phase 2b study.
