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.

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.

Inclusion criteria

* Severe COVID-19: Adult patients admitted to the hospital through the Emergency Department (ED) requiring oxygen therapy (any level) to maintain oxygen saturation (SaO2) \> 90% * COVID positive by polymerase chain reaction (PCR) on hospital admission * Hospitalized patients aged 18 years or greater

Exclusion criteria

* Pre-existing chronic kidney disease * New use of or change in dose of ACE-inhibitors or angiotensin receptor blocker (ARB) within the last 6 months * Acute kidney injury at the time of enrollment defined as either increase pf serum creatinine by more than 50% or 0.3 mg/dL above baseline or estimated creatinine clearance (by MDRD) of less than 60 ml/min (if no baseline serum creatinine available) * Pregnant and breastfeeding women * Contraindicated medications: new use or change of medications from start of trial (start of an ACE inhibitor or ARB within 6 months of trial).
