NCT04801056

Brief Summary

TB006, a monoclonal antibody, is an anti-inflammatory and anti-fibrotic agent that reduces the severity of underlying diseases in COVID-19 patients. The primary objective of TB006 treatment is to decrease the potential acute severe deterioration in outpatient COVID-19 patients with underlying diseases, such as diabetes, hypertension, and cancer. TB006 has been developed to treat the ambulatory patients with diagnosed mild to moderate COVID-19 who are considered at low risk for severe disease or hospitalization.

Study Arms (2)

TB006

EXPERIMENTAL

During the SAD study, subjects will receive a single dose of TB006 (at the dosage level of 10 \~ 50 mg/kg) administered via i.v. infusion for 60 mins. In addition, a sentinel cohort of 5 mg/kg will be open for enrollment and double-blinded randomization first, with 2 patients randomized to active/TB006 arm, to assess preliminary safety and tolerability of study drug, and to determine cohort expansion and dose escalation. Upon the completion of sentinel cohort and all subjects are safe and well tolerate study treatment, regular dose escalation will start.

Drug: TB006

Placebo

PLACEBO COMPARATOR

During the SAD study, subjects will receive a single dose of the placebo administered via i.v. infusion for 60 mins. In addition, the corresponding sentinel placebo group will include 1 patient to placebo arm. Upon the completion of sentinel cohort and all subjects are safe and well tolerate study treatment, regular dose escalation will start.

  • Mild (without shortness of breath or dyspnea): Fever, cough, sore throat, malaise, headache, muscle pain, gastrointestinal symptoms
  • Moderate: Any symptom of mild illness, shortness of breath with excursion, clinically suggestive of moderate illness with COVID-19, such as respiratory rate ≥ 20 breaths per minute, saturation of oxygen (SpO2) \> 93% on room air at sea level, heart rate ≥ 90 beats per minute
  • At low risk for progressing to severe COVID-19 and/or hospitalization.
  • Adequate organ function at screening as evidenced by:
  • Hemoglobin \> 10.9 g/dL
  • Absolute neutrophil count (ANC) \> 1.0 × 10\^9/L
  • Platelets \> 125 × 10\^9/L
  • Alanine Aminotransferase (ALT) or aspartate aminotransferase (AST) \< 1.25 × upper limit of normal (ULN)

  • Normal electrocardiogram with QTcF of ≤ 450 ms

You may not qualify if:

  • Participation in any other clinical trial of an experimental treatment for COVID-19

  • SEVERE:
  • Any symptom of severe, systematic illness, including moderate illness, shortness of breath, or respiratory distress
  • Clinically suggestive of severe illness with COVID-19, such as respiratory rate ≥ 30 breaths per minute, heart rate ≥ 125 per minute, saturation of oxygen (SpO2) ≤ 93% on room air at sea level, or PaO2/FiO2 \< 300
  • CRITICAL ILLNESS (one of the following):
  • Respiratory failure defined based on resource utilization requiring at least one of the following:
  • Endotracheal intubation and mechanical ventilation, oxygen delivered by high483 flow nasal cannula (heated, humidified, oxygen delivered via reinforced nasal cannula at flow rates \> 20 L/min with fraction of delivered oxygen ≥ 0.5)
  • Noninvasive positive pressure ventilation, ECMO, or clinical diagnosis of respiratory failure (i.e., clinical need for one of the preceding therapies, but preceding therapies not able to be administered in setting of resource limitation)
  • Shock (defined by systolic blood pressure \< 90 mm Hg, or diastolic blood pressure \< 60 mm Hg or requiring vasopressors)
