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
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.

Participation Criteria
Eligibility Criteria
Ages Eligible for Study
Accepts Healthy Volunteers
Description
Inclusion Criteria:
- Men and women ≥18 years of age at the time of consent.
- Laboratory-confirmed diagnosis of COVID-19.
- Hospitalized for COVID-19 related respiratory disease.
Patient belongs to one of the following two categories in the nine-point COVID-19 severity scale:
- Hospitalized, requiring intubation and mechanical ventilation - Level 6 of the nine-point COVID-19 severity scale.
- Hospitalized and intubated with additional organ support - pressors, RRT, ECMO - Level 7 of the nine-point COVID-19 severity scale.
- 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.
- 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.
Exclusion Criteria:
- The subject is a female who is breastfeeding or pregnant.
- Known hypersensitivity to EB05 or its excipients.
- In the opinion of the investigator, death is imminent and inevitable or patient will be discharged within the next 48 - 72 hours, irrespective of the provision of treatment.
- Experiencing cardiac arrest while hospitalized with COVID-19.
Active participation in other immunomodulator or immunosuppressant drug clinical trials.
a. Participation in COVID-19 antiviral, anticoagulant and convalescent plasma trials may be permitted; however, the decision to enroll a patient who is participating in other clinical trials will be dealt with on a case-by-case basis.
Treatment with immunomodulator or immunosuppressant drugs, including but not limited to TNF inhibitors and anti-IL-1 agents within 5 half-lives or 30 days (whichever is longer) before randomization. Except for the following, which are permitted:
- Treatment with immunomodulator, or immunosuppressant drugs, such as corticosteroids, as part of SOC for COVID-19
- Transplant patients
- Known other clinical conditions that contraindicate EB05 and cannot be treated or solved according to the judgment of the clinician.
- Patient has been intubated or mechanically ventilated for more than 72 hours prior to administration of the investigational product.
- Patient has been intubated and then extubated during the current hospitalization prior to administration of the investigational product.
- Patient has experienced meaningful clinical improvement in the severity of disease prior to administration of the investigational product.

Mortality rate at Day 28 from IP administration.
Time Frame: 28 days

Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Proportion of patients with clinical improvement at Day 28
Time Frame: 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
Time Frame: 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. |
