Tocilizumab for the Prevention of Respiratory Failure and Death in Patients with Severe COVID-19 Infection

Trial Status: complete

This phase II trial studies the effect of tocilizumab in preventing respiratory failure and death in patients with severe COVID-19 infection. Part of the complications from the COVID-19 infection may be due to the virus causing damage to the lungs, some of this damage may be caused by an extreme inflammatory reaction produced by the immune system as it tries to fight off the virus. A protein called IL-6 (interleukin 6) plays a major role in this type of inflammation. Tocilizumab may prevent IL-6 from attaching to cells. By blocking IL-6, tocilizumab may prevent damage to the lungs and reduce the need for treatment with a mechanical ventilator. If a patient is already receiving mechanical ventilation to assist with breathing, tocilizumab may improve the patient’s condition enough to allow this treatment to be stopped.
