Brief Summary:
The purpose of this study is to determine if administration of angiotensin-(1-7) (TXA127) prevents acute kidney injury and deterioration into multi-organ failure in patients with severe COVID-19. Participants will undergo a 10-day treatment with either placebo or study drug. The drug will be administered intravenously for 3 hours once each day for 10 days consecutively.

Condition or disease Intervention/treatment Phase
COVID-19 Drug: TXA127 Drug: Placebo Phase 2

Detailed Description:
Corona virus disease 2019 (COVID-19) has been associated with severe respiratory and multiorgan failure. Research shows that COVID-19 reduces levels of angiotensin-converting enzyme-2 (ACE-2), an enzyme that converts angiotensin II to angiotensin 1-7 (known as TXA127). COVID-19 reduces levels of ACE-2 and therefore angiotensin 1-7 and as a result, angiotensin II levels are going to be increased. Many clinical observations in COVID-19 have shown the high incidence of acute kidney injury that may be due to excessive levels of angiotensin II. The investigators hypothesize that administration of angiotensin (1-7) replaces levels of ACE-2 in COVID-19 and thereby ameliorates deterioration of multi-organ failure and specifically acute kidney injury.
