Can an arthritis drug tame severe COVID-19?
NCT ID NCT04412772
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested the drug tocilizumab (Actemra) in hospitalized adults with severe COVID-19 and signs of inflammation. Participants received either the drug or a placebo, with the goal of improving clinical status by day 28. The trial was terminated early after enrolling only 20 of the planned 300 patients, limiting what can be concluded.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- tocilizumab (Actemra)
- What this could lead to
- If successful, this could provide a treatment option for severe COVID-19 by reducing inflammation and improving recovery.
- What could go wrong
- The trial was terminated early with only 20 participants, so results are limited. Tocilizumab may not work for all patients and carries risks like infection.

Inclusion Criteria: * ii. Hospitalized with COVID-19 pneumonia, based on chest X-ray or CT scan AND iii. Evidence of hyperinflammation: IL-6\>40pg/mL (if available) OR CRP \>2 mg/dL OR ferritin \>2000 ng/mL AND iv. One or more of the following: impending need for requiring invasive or non-invasive mechanical ventilation OR shock requiring vasopressor (without evidence of bacterial / fungal infection) OR need for extracorporeal membrane oxygenation (ECMO) OR severe, refractor ARDS (PaO2/FiO2\<200 mmHg) Exclusion Criteria: Known severe allergic reactions to tocilizumab or other monoclonal antibodies * Active tuberculosis infection based on history * 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 * Have received oral anti-rejection or immunomodulatory drugs (including tocilizumab) with the past 6 months * Participating in other drug clinical trials (participation in COVID-19 trials allowed) * Self-reported pregnant or breastfeeding * 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 * Alanine aminotransferase (ALT) or aspartate aminotransferase (AST) \> 10 x upper limit of normal (ULN) detected within 24 hours at baseline * Absolute neutrophil count (ANC) \< 1000/mL at baseline * Platelet count \< 50,000/mL at baseline
