A Randomized, Double-Blind, Placebo-Controlled Study to Evaluate the Safety and Efficacy of EB05 + SOC vs. Placebo + SOC in Adult Hospitalized Patients With COVID-19

2026년 10월 26일 업데이트: Edesa Biotech Inc.

COVID-19 patients who develop severe disease often develop acute respiratory distress syndrome (ARDS) as a result of a dysregulated immune response. This in turn stimulates a pro-inflammatory cascade ("cytokine storm") as well as emergency myelopoiesis.

This proinflammatory cascade is activated when viral-mediated cell damage occurs in the lungs, resulting in the release of damage-signaling alarmin molecules such as S100A8/A9 (Calprotectin), HMGB1, Resistin, and oxidized phospholipids. These damage-associated molecular patterns (DAMPs) are recognized by the pattern recognition receptor Toll-Like Receptor 4 (TLR4) found on macrophages, dendritic cells and other innate immune cells and result in additional release of pro-inflammatory molecules. Several recent studies have shown that S100A8/A9 serum levels in hospitalized COVID-19 patients positively correlate with both neutrophil count and disease severity. Taken together the DAMP-TLR4 interaction forms a central axis in the innate immune system and is a key driver of the pathological inflammation observed in COVID-19. We hypothesis that targeting the initial step in the signalling pathways of these DAMPs in innate immunity offers the best hope for controlling the exaggerated host response to SARS-CoV-2 infection.

EB05 has demonstrated safety in two clinical studies (>120 patients) and was able to block LPS-induced (TLR4 agonist) IL-6 release in humans. Given, this extensive body of evidence we believe EB05 could ameliorate ARDS due to COVID-19, significantly reducing ventilation rates and mortality.

  2. Laboratory-confirmed diagnosis of COVID-19.

  3. Hospitalized for COVID-19 related respiratory disease.

  4. Patient belongs to one of the following two categories in the nine-point COVID-19 severity scale:

    1. Hospitalized, requiring intubation and mechanical ventilation - Level 6 of the nine-point COVID-19 severity scale.
    2. Hospitalized and intubated with additional organ support - pressors, RRT, ECMO - Level 7 of the nine-point COVID-19 severity scale.
  5. For women of childbearing potential involved in any sexual intercourse that could lead to pregnancy: Negative pregnancy test and willingness to use contraceptive (consistent with local regulations) during the study period.

측정값 설명
기간
Proportion of patients with clinical improvement at Day 28 (Phase 2 and 3)
기간: 28 days

The proportion of patients with clinical improvement, defined as a decrease of two points or more on the World Health Organization (WHO) 9 - point ordinal scale at Day 28 from IP administration.

The severity of COVID-19 disease is classified according to the WHO 9-point ordinal scale. The minimum value of 0 is associated with an "uninfected" stage wherein no clinical or virological evidence of infection is present. The maximum value of 8 is associated with death. A higher score reflects a worse outcome.

Proportion of patients with clinical improvement at Day 60 (Phase 2)
기간: 60 days

The proportion of patients with clinical improvement, defined as a decrease of two points or more on the World Health Organization (WHO) 9 - point ordinal scale at Day 60 from IP administration.

The severity of COVID-19 disease is classified according to the WHO 9-point ordinal scale. The minimum value of 0 is associated with an "uninfected" stage wherein no clinical or virological evidence of infection is present. The maximum value of 8 is associated with death.
