This is an investigator initiated, open label, multicenter, two arm, randomized study to compare the impact of adding an ARB to the Standard of Care (SOC) to the SOC without an ARB. Randomization ratio will be 1:1. The goal of this study is to identify whether or not ARBs have an impact on inhibiting the progression to respiratory failure requiring mechanical ventilation in patients with mild to moderate hypoxia in the setting of COVID-19. The addition of an ARB to the standard of care treatment for these patients may be beneficial in abating acute lung injury in patients in early stages of SARS-CoV-2 induced hypoxia.
