Outcome Measures

Primary Outcomes (1)

  • Evaluate the Effect of RBT-9 Versus Placebo on Clinical Status of COVID-19 Patients as Measured Using the 8-point World Health Organization (WHO) Ordinal Clinical Scale

    Determining severity of COVID-19 in patients measured using the 8-point World Health Organization (WHO) Ordinal Clinical Scale which measures the clinical status of a subject at the first assessment of a given day with category 1, most favorable, and category 8, least favorable (1. Ambulatory, no limitation of activities; 2. Ambulatory, limitation of activities; 3. Hospitalized, no oxygen therapy; 4. Hospitalized, oxygen by mask or nasal prongs; 5. Hospitalized, non-invasive ventilation or high-flow oxygen; 6. Hospitalized, intubation and mechanical ventilation; 7. Hospitalized, ventilation plus additional organ support - pressors, renal replacement therapy \[RRT\], extracorporeal membrane oxygenation \[ECMO\]; 8. Death)

    baseline and 7 days, baseline and 28 days

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Male or female, ≥18 years of age at Screening.
  • Confirmed infection with SARS-CoV-2.
  • High risk of COVID-19 disease progression, defined as:
  • years of age with lymphopenia AND 1 additional risk factor (described below)
  • years of age without lymphopenia AND 2 risk factors (described below)
  • ≥70 years of age with lymphopenia OR 1 other risk factor (described below)
  • Risk Factors:
  • Documented history of coronary artery disease
  • Heart failure (New York Heart Association Class 3 or 4)
  • Chronic lung disease (eg, asthma or chronic obstructive pulmonary disease) requiring treatment
  • Documented history of stroke
  • Diabetes mellitus, requiring at least 1 prescription medicine for management
  • Documented chronic kidney disease with an estimated glomerular filtration rate \<30 mL/min, not on dialysis
  • Obesity (Class 2 or 3; body mass index \>34.9 kg/m2)
  • On immunosuppressive therapy
  • +6 more criteria

You may not qualify if:

  • Anticipated need for ICU care and/or ventilatory support (invasive or noninvasive) within 24 hours.
  • Evidence of acute cardiac injury, as determined by the Investigator at the time of Screening. This may be based upon clinical signs and symptoms, ECG findings, or elevated troponin I levels.
  • Evidence of acute kidney injury not due to pre-renal azotemia or urinary tract obstruction at the time of Screening.
  • Oxygen saturation \<90% on supplemental oxygen with a nasal cannula, including high-flow oxygen at the time of Screening.
  • Requires non-invasive ventilation at the time of Screening.
  • Requires dialysis at the time of Screening.
  • Has received or is receiving anti-IL-6 therapies (eg, Tocilizumab, Sarilumab, Siltuximab, etc) for the treatment of COVID-19; subjects receiving anti-IL-6 therapies for underlying medical conditions unrelated to COVID-19 are not excluded from eligibility.
  • Pregnant or lactating.
  • History of photosensitivity or active skin disease that, in the opinion of the Investigator, could be worsened by RBT-9.
  • Known hypersensitivity or previous anaphylaxis to RBT-9 (stannous protoporphyrin) or any tin-based product.
  • Treatment with an investigational drug or participation in an interventional trial within 30 days prior to the first dose of study drug.
  • Inability to comply with the requirements of the study protocol.
