Brief summary: In this trial, patients that are severely affected by the disease COVID-19 will either receive infliximab, an anti-inflammatory drug, or standard therapy. Infliximab is a drug that inhibits inflammation by blocking a molecule called TNFα. The patients receive the drug via an infusion into a vein. The primary goal of this trial is to see whether the drug infliximab affects how many people died from COVID-19 after 28 days by comparing patients receiving the drug in addition to standard therapy with patients only receiving standard therapy.

Furthermore, this trial will look at whether the drug is safe to use in these patients, whether it has an effect on the inflammation and whether it can affect how ill patients are after surviving the disease.

The trial is conducted in more than one hospital. As COVID-19 is responsible for a global pandemic, positive results of this trial could affect patients, healthcare and economic systems worldwide.

Detailed description: The long-term goal of this research project is to develop a new pharmacological treatment strategy for patients with COVID-19. Its primary aim is the assessment of efficacy and safety of the TNFα antibody infliximab in the treatment of patients with severe COVID-19 in a phase-2 trial. Infliximab is expected to attenuate the inflammatory reaction in patients and thereby positively influence the course of the disease.

The primary endpoint is the difference in 28-day-mortality of patients with severe COVID-19 receiving one dose of 5mg per kg body weight infliximab intravenously in addition to the standard of care (intervention group) compared with patients receiving standard of care (control group).

Secondary aims of this trial include the assessment of the safety of the TNFα antibody infliximab in the treatment of patients with severe COVID-19, of its effect on an excessive immune response and of its effect on the morbidity and prognosis as well as the characterization of the analytical cohorts.

The multi-centre design facilitates the transferability of study results to hospitals of similar healthcare level. Should infliximab prove to be superior to standard therapy, this could be reflected in a reduced disease severity and mortality.

The results of this study could influence the therapy of patients with COVID-19 worldwide and affect the course of the disease worldwide, as infliximab is approved by several international drug agencies and globally available. Due to the high incidence of COVID-19 worldwide and the immense effects of the pandemic on societies, health care and economic systems, any progress in the treatment of this new disease would constitute a great success. This would not only impact individual patients but also have positive economic effects.
