The COVID-RASi Trial (COVID-19)

Overview

The COVID-RASi study is an international randomized clinical trial that will evaluate the potential benefit of angiotensin modulators on clinical outcomes, in COVID-19 patients. The purpose of this study is to determine if renin-angiotensin system inhibitors (RASi), with angiotensin-converting enzyme inhibitors (ACEi) or angiotensin II receptor blockers (ARB), has a beneficial effect in patients with COVID-19 infections, by reducing ICU admission, ventilator requirement or death. We would also like to determine if there are differences between ACEi and ARB therapeutic treatments. With the increasing potential of long COVID symptoms, at the 1 year follow up, a primary endpoint will be the quality of life of study participants, as assessed by ongoing symptoms and/or the standardized questionnaires.

Detailed Description

The goal is to determine if RASi with ACEi or ARB, has a beneficial effect in patients with COVID-19 infections, by reducing hospitalizations, ICU admission, ventilator requirement or death. This is a multi-centre study, conducted in major centres treating COVID-19 patients in-hospital and in various outpatient settings. Patients admitted to hospital or outpatients that test positive for COVID-19 and meet the inclusion/exclusion criteria will be eligible to participate in this study. All study participants will not be on RASi (ACEi/ARB) treatment at the time of consent. Participants will be randomized to initiation of ACEi vs ARB treatment vs no RASi treatment as part of care for COVID-19 in a 1:1:1 ratio. The patient will be followed by their physician according to usual clinical care. Sites will complete research-related follow-ups at 24 hours, 7 and 28 days to asssess patient's clinical status, side effects and the achievement of clinical endpoints by telephone interviews. Phone call follow ups will also be conducted at 6 months and 12 months after enrollment in the study.

Interventions

  • Drug: Angiotensin converting enzyme inhibitor
    • The study recommends physicians to select an ACEi with proven benefit in cardiovascular diseases such as perindopril, ramipril or enalapril. Lab values will be obtained during baseline. The patient will be followed by the physician clinically, with recommended laboratory testing in one week, including renal function, potassium assessment, and dose adjustments as appropriate.
  • Drug: Angiotensin II Receptor Blockers
    • The study recommends physicians to select evidence-based ARBs such as candesartan or valsartan or losartan. Lab values will be obtained during baseline. The patient will be followed by the physician clinically, with recommended laboratory testing in one week, and dose adjustments as appropriate.

Arms, Groups and Cohorts

  • No Intervention: No Treatment (Standard of Care)
    • Participants will be treated as per standardized care pathway according to province/state and institutional guidelines. Physicians will be reminded not to start ACEi or ARB throughout admission or to outpatients until active study participation is complete at 28 days post symptoms.
  • Experimental: ACEi treatment
    • The physician will initiate any ACE inhibitor and dose at their discretion.
  • Experimental: ARB treatment
    • The physician will initiate any ARB and dose at their discretion.
