The objective of this clinical trial is to evaluate the efficacy and safety of IL-6 driven personalized treatment strategy with tocilizumab in patients with severe COVID-19 pneumonia.
Trial design
Randomized, controlled, open-label, single-center trial of a tocilizumab treatment strategy in adult patients hospitalized with severe COVID-19 pneumonia and IL-6 serum levels > 40 pg/mL.
Methods
Patients were randomized 1:1 to receive standard of care (SOC) or SOC plus one dose of tocilizumab. The primary outcome was death or need for invasive mechanical ventilation (IMV) within 28 days after randomization. Secondary outcomes included ICU admission, days on IMV and hospital stay. A meta-analysis of clinical trials to evaluate the effect of tocilizumab on mortality and need of IMV in patients with COVID-19 pneumonia was performed.
Results
Sixty-two patients were included: 30 in the SOC arm and 32 in the standard-treatment plus tocilizumab arm. The primary outcome occurred in 12.9% in the tocilizumab arm and 32.3% in the SOC arm(p = 0.068). There was a trend towards fewer days on IMV (7.5 vs 19.5 days, p = 0.073) and a shorter hospital stay (4 vs 8 days, p = 0.134) in the tocilizumab group. No serious adverse events were reported. The meta-analysis revealed a RR for death or IMV of 0.83 (95% CI: 0.77–0.89) in patients receiving tocilizumab, compared to patients receiving SOC.
Conclusion
Tocilizumab could be effective to prevent death or IMV in patients with severe COVID-19 pneumonia and high IL-6 serum levels. Safety profile of tocilizumab does not arise major concern in patients with severe COVID19.Open Access Funding provided by Universitat Autonoma de Barcelona.
