Ramipril for the Treatment of COVID-19

Study Overview
=================
Brief Summary
-----------------
In this study we propose to treat 560 patients with ramipril or placebo for 14 days. After an initial evaluation for COVID-19 status, medical history, and symptom assessment, patients will receive either 2.5 mg/day of ramipril or placebo. Patients' symptoms and study endpoints will be monitored at regular intervals. After 14 days, patients will undergo a laboratory assessment and an end-of-treatment follow-up visit at day 28. The primary endpoints of successful therapy will be improved survival, reductions in ICU admissions, and/or reductions in use of mechanical ventilator support.

Detailed Description
-----------------
Ramipril has not been studied in SARS-CoV-2 infected patients. In this study we propose to treat 560 patients with ramipril or placebo for 14 days. After an initial evaluation for COVID-19 status, medical history, and symptom assessment, patients will receive either 2.5 mg/day of ramipril or placebo. Patients' symptoms and study endpoints will be monitored at regular intervals. Additional follow-up will be performed at day 28. As an exploratory objective, biomarkers of the RAAS axis will also be monitored. The primary endpoints of successful therapy will be improved survival, reductions in ICU admissions, and/or reductions in use of mechanical ventilator support. Secondary endpoints will be the proportion of patients needing continued hospitalization, time to mortality, time to ICU admission, time to discharge from hospital, proportion of patients developing hypotension and needing pressor support, and proportion of patients developing septic shock.
