Clinical Trial to Evaluate the Effectiveness and Safety of Tocilizumab for Treating Patients With COVID-19 Pneumonia

COVID-19 Clinical Trial

Official title: A Multicentre, Open-label Clinical Trial to Evaluate the Effectiveness and Safety of Intravenous Tocilizumab for Treating Patients With COVID-19 Pneumonia: the BREATH-19 Study

Status Completed

Clinical Trial Summary

At present, no treatment has been approved for COVID-19. However, in light of the increased interest on using the anti-cytokine therapy targeting IL-6 tocilizumab in COVID-19 infected patients due to its potential benefit, the Spanish Agency for Medicine and Health Products (Agencia Española de Medicamentos y Productos Sanitarios, AEMPS) have initiated the controlled distribution of the drug. Tocilizumab is indeed proposed as a potential treatment for severe COVID-19 in Spain. Based on the positive results of tocilizumab in the treatment of COVID-19 patients and the experience of tocilizumab in inducing rapid reversal of CSS in other pathologies several clinical trials and observational studies are being conducted to assess the effectiveness and safety of tocilizumab in COVID-19 patients. Further studies with a large sample size are required to confirm the effectiveness of tocilizumab in patients with COVID-19 pneumonia. The need for the management of severe COVID-19 disease is imperative, and every effort should be made to collect relevant clinical outcomes. The aim of the present study is to evaluate the effectiveness of IV tocilizumab in treating patients with COVID-19 pneumonia who are currently hospitalized or admitted to ICU by describing improvement of respiratory function and mortality rate. This large real-world cohort therefore provides a unique opportunity to study this potential medicine during the current emergency situation, and support the findings from other ongoing clinical trials and observational studies, such as the Roche-sponsored Phase III study that is planned to start early April.

Clinical Trial Description

Cytokine storm syndrome (CSS) is caused by the excessive release of cytokines during an exaggerated immune response. CSS can be triggered by infections or therapeutic interventions, being more severe depending on the degree and duration of immune activation. CSS is as a significant on-target side-effect of chimeric antigen receptor (CAR) T-cell therapies, which have been subject to assessment for the treatment of haematological malignancies. Tocilizumab (intravenous, IV) is indicated for the treatment of chimeric antigen receptor CAR T cell-induced severe or life-threatening CSS. Based on the experience with tocilizumab in the CSS, and that some patients infected with SARS-CoV-2 can develop CSS, leading to potentially fatal damage to lung tissue, the drug is being investigated in China and Italy, and clinical trials are being conducted/planned in these and several other countries. Real-word experience with tocilizumab IV have shown that in a substantial proportion of COVID-19 patients with severe pneumonia, fever returned to normal and respiratory function based on oxygen intake and lung opacities improved remarkably. Laboratory parameters such as C-reactive protein (CRP) that seem to be increased in patients infected decreased significantly with tocilizumab, and lymphocytes levels also returned to normal. All these findings have led the Spanish Agency for Medicine and Health Products (AEMPS) to initiate the controlled distribution of tocilizumab IV, in light of the increased interest on the anti-cytokine therapy targeting IL-6 in COVID-19 infected patients. Therefore, tocilizumab might be among the therapeutic armamentarium for preventing the fatal consequences of acute respiratory and multi organ failure in around 20% of the COVID-19 infected patients. The aim of the present study is to evaluate the effectiveness and safety of IV tocilizumab in patients with COVID-19 severe pneumonia who are currently hospitalized or admitted to ICU. This large real-world cohort provides a unique opportunity to study a potential medicine during the current emergency situation, and support the findings from the Roche-sponsored Phase III study that is planned to start in early April. ;
