Brief Summary:

Rationale: The renin-angiotensin-aldosterone system (RAAS) dysregulation may play a central role in the pathophysiology of Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) infection associated acute lung injury (ALI) / acute respiratory distress syndrome (ARDS). In the RAAS, Angiotensin I (Ang I) is converted to angiotensin II (Ang II) by angiotensin converting enzyme (ACE). Ang II mediates vasoconstrictive, pro-inflammatory and pro-oxidative effects through agonism at Ang II type 1 receptor (AT1R). ACE2 converts Ang II to angiotensin 1-7 (Ang1-7), which finally binds to Mas receptor (MasR) and mediates many beneficial actions, including vasodilation and anti-inflammatory, anti-oxidant and antiapoptotic effects. ACE2, a homologue of ACE, is an integral cell membrane protein with a catalytic domain on the extracellular surface exposed to vasoactive peptides. SARS-CoV-2 penetrates the cell through ACE2, and the increase of this receptor (due to the use of ACE inhibitors or angiotensin receptor blockers [ARBs]) may facilitate SARS-CoV-2 infection, which might increase the risk of developing severe and fatal SARS-CoV-2 infection. However, through upregulation of ACE2, ACE inhibitors/ARBs can exert anti-inflammatory and antioxidative effects, which may be beneficial in preventing ALI and ARDS.

Objective: To evaluate the effectiveness and safety of telmisartan in respiratory failure due to COVID-19.

Study design: This is an open label, phase 2 clinical trial. Study population: Adult hospitalized SARS-CoV-2-infected patients (n=60). Intervention: The active-treatment arm will receive telmisartan 40 mg daily and the control arm will receive standard care. Treatment duration will be 14 days or up to hospital discharge <14 days or occurrence of the primary endpoint if <14 days.

Main study endpoint: The primary study endpoint is the occurrence within 14 days of randomization of either: 1) Mechanical ventilation or 2) Death.

Primary Outcome Measures :
  1. Death [ Time Frame: Within 30 days ]
    Death is defined as all-cause mortality

  2. Mechanical ventilation [ Time Frame: Within 14 days ]
    Occurrence of mechanical ventilation

Secondary Outcome Measures :
  1. Occurrence of acute kidney injury [ Time Frame: Within 14 days ]
    Defined as a 50% decline in estimated glomerular filtration rate relative to baseline, or decrease of >30 ml/min/1.73m2 and to a value below 60 ml/min/1.73m2

  2. Incidence of hypotension [ Time Frame: Within 14 days ]
    Incidence of episodes of blood pressure less than 90 mm Hg systolic or 60 mm Hg diastolic

  3. Incidence of hypotension requiring vasopressors [ Time Frame: Within 14 days ]
    Outcome reported as the number of participants in each arm requiring the use of vasopressors for hypotension

  4. Incidence of Sepsis [ Time Frame: Within 14 days ]
    Outcome reported as the number of participants in each arm who experience sepsis, defined as the presence of at least 2 of the following clinical criteria together (qSOFA score): respiratory rate of 22/min or greater, altered mentation, or systolic blood pressure of 100 mm Hg or less

  5. Hospital length of stay [ Time Frame: Within 14 days ]
    Hospital length of stay (days)

Layout table for eligibility information
Ages Eligible for Study:   18 Years and older   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Age greater than or equal to 18 years of age.
  • Admitted to the Hospital Regional de Alta Especialidad de Zumpango.
  • Confirmed SARS-CoV-2 infection with either: positive laboratory test for SARS-CoV-2; or positive CT thorax diagnostic for SARS-CoV-2 infection according to the prevailing criteria.
  • Hypoxic respiratory failure: SpO2 ≤94% on room OR tachypnea (respiratory rate ≥22 breaths/min).


  • Within 24 hours of confirmed in-hospital SARS-CoV-2 infection diagnosis OR
  • within 24 hours of hospital admission in case of pre-hospital confirmed SARS-CoV-2 infection.
  • In case there is a lack of laboratory tests for SARS-CoV-2 in a potentially eligible patient, a positive laboratory test for SARS-CoV-2 will be no longer required. In that case, the potentially eligible patient needs to meet the prevailing criteria for the diagnosis of SARS-CoV-2 infection, such as typical abnormalities on pulmonary CT in the setting of high clinical suspicion of SARS-CoV-2 infection.

Exclusion Criteria:

  • Admitted to ICU prior to randomization.
  • Currently taking an an angiotensin converting enzyme inhibitor (ACEi) or Angiotensin receptor blocker (ARB).
  • Use of other investigational drugs at the time of enrollment
  • Prior reaction or intolerance to an ARB; or severe intolerance to an ACEi, defined as angio-oedema requiring medical intervention.
  • Systolic blood pressure < 105 mmHg or diastolic blood pressure <65mmHg.
  • Potassium greater than 5.5 mEq/L within 4 weeks of study enrollment.
  • Estimated Glomerular Filtration Rate (eGFR) of < 30ml/min/1.73 m2 within 4 weeks of study initiation.
  • A known history of renal artery stenosis.
  • AST and/or ALT > 3 times the upper limit of normal within 4 weeks of study enrollment.
  • Severe liver dysfunction (Child-Pugh score C), biliary cirrhosis or cholestasis.
  • Severe volume depletion or severe acute kidney injury.
  • Inability to obtain informed consent.
  • Pregnancy or breastfeeding.
