Details and patient eligibility

About

The purpose of this trial is to assess the safety, tolerability and treatment effect of the orally administered Caspase-1 inhibitor, belnacasan, for the treatment of patients with mild to moderate COVID-19 and to generate proof of concept for future trials.

Full description

COVID-19 is an acute respiratory disease caused by the SARS-CoV-2 virus which has impacted the lives of millions of patients. Though vaccines and preventive treatments such as monoclonal antibodies, steroids, and anti-virals have been established, they do not specifically target the resulting inflammatory response and complications the virus causes.

This study aims to evaluate how safe and effective a particular oral medication, Belnacasan, is in diminishing your body's inflammatory response, which may go into overdrive when infected with the virus. This overly activated immune response can become uncontrolled resulting in cell death and the release of damaging proteins which can cause major harm to all organs throughout the body.

Belnacasan prevents the activation of a particular enzyme, Caspase-1, which plays a major role in activating this damaging immune response brought on by COVID-19. The goal of this medication being a more targeted treatment that aims to prevent the devastating immune response.
