In addition to the drugs mentioned in this section, current approaches to COVID-19 therapeutics also include other compounds with the potential to ameliorate either inflammation or thrombosis triggered by SARS-CoV-2, such as colchicine, Bruton tyrosine kinase inhibitors and activated protein C. However, while some studies are in a more advanced stage of analysis, others are still in the theoretical field and thus are not discussed in detail (191, 233, 234). This evidence concerns the gene PROC and COVID-19.
