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

26 ottobre 2026 aggiornato da: 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.

Descrizione

Inclusion Criteria:

  1. Men and women ≥18 years of age at the time of consent.

  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.

  6. Signed informed consent obtained by any patient capable of giving consent, or, when the patient is not capable of giving consent, from his or her legal/authorized representatives.

Misure di risultato primarie

Misura del risultato
Misura Descrizione
Lasso di tempo
Mortality rate at Day 28 from IP administration. (Phase 2 and 3)
Lasso di tempo: 28 days

For the current study, the primary efficacy outcome measure will be the mortality rate from IP administration. Mortality is the most clinically relevant therapeutic endpoint for this population that is on IMV. The primary endpoint will be assessed at 28-days after treatment initiation.

28 days

Misure di risultato secondarie

Misura del risultato
Misura Descrizione
Lasso di tempo
Proportion of patients with clinical improvement at Day 28 (Phase 2 and 3)
Lasso di tempo: 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.

28 days
Proportion of patients with clinical improvement at Day 60 (Phase 2)
Lasso di tempo: 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. A higher score reflects a worse outcome.
