Promising Adjunct Medicines in the Protocol of COVID-19 Clinical Trial.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is the causative organism of COVID-19. Since this disease is considered new and does not have an approved curative protocol, many researchers have tackled the possible options for COVID-19 prevention and therapeutic approaches. We address herein the phenomena of cytokine storm (the main cause of death) associating with the late stage of COVID19. Cytokine storm is undertaken in an attempt to provide information about its possible underlying causes, and to clarify some points that can be of value in guiding treatment practices for a clinical trial.
