      Trial Summary

      This study (EMPACTA) will a) evaluate the efficacy and safety of tocilizumab (TCZ) compared with a placebo in combination with standard of care (SOC) in hospitalized participants with COVID-19 pneumonia, and b) include an optional long-term extension for eligible participants to explore the long-term sequelae of resolved COVID-19 pneumonia.

      Eligibility Criteria

      All Gender
      ≥18 Years Age
      No Healthy Volunteers
      Inclusion Criteria
      • Hospitalized
      • COVID-19 pneumonia confirmed by a positive polymerase chain reaction (PCR) of any specimen and radiographic imaging
      • SpO2 < 94% while on ambient air

      Inclusion Criteria Specific to Long-Term Extension

      • Participated in Study ML42528 (EMPACTA) (includes participants who completed or discontinued early from the main study)
      Exclusion Criteria
      • Known severe allergic reactions to TCZ or other monoclonal antibodies
      • Require continuous positive airway pressure (CPAP), bilevel positive airway pressure (BIPAP), or invasive mechanical ventilation
      • Suspected active bacterial, fungal, viral, or other infection (besides COVID-19)
      • In the opinion of the investigator, progression to death is imminent and inevitable within the next 24 hours, irrespective of the provision of treatments
      • Immunocompromised (besides well-controlled HIV) or on immunosuppressive therapy (except for steroids for COVID), advanced cancer
      • Have received oral anti-rejection or immunomodulatory drugs (including TCZ) within the past 3 months
      • Participating in another interleukin (IL)-6 antagonist clinical trial or other drug clinical trials (participation in COVID-19 anti-viral trials may be permitted if approved by Medical Monitor)
      • Alanine aminotransferase (ALT) or aspartate aminotransferase (AST) > 10 x upper limit of normal (ULN) detected within 24 hours at screening (according to local laboratory reference ranges)
      • Absolute neutrophil count (ANC) < 1000/uL at screening (according to local laboratory reference ranges)
      • Platelet count < 50,000/uL at screening (according to local laboratory reference ranges)
      • Pregnant or breastfeeding, or positive pregnancy test in a pre-dose examination
      • Treatment with an investigational drug within 5 half lives or 30 days (whichever is longer) of randomization (investigational COVID-19 antivirals may be permitted if approved by Medical Monitor)
      • Any serious medical condition or abnormality of clinical laboratory tests that, in the investigator's judgment, precludes the patient's safe participation in and completion of the study
      • Any history of Diverticulitis or GI perforation
      • Use of systemic corticosteroids unless on a stable chronic dose
