The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details.
ClinicalTrials.gov Identifier: NCT04360551
Recruitment Status : Terminated (Decrease in COVID-19 cases locally)

Brief Summary:
This study will enroll 40 symptomatic outpatients tested positive for Coronavirus 2019 (COVID-19). Patients to be randomized 1:1 to Telmisartan (40 mg) vs placebo to be administered orally once daily x 21 days. Daily, the study patients will be asked to keep a record of the severity of their fever, dyspnea and fatigue and take their blood pressure (BP) and temperature. Study visits to occur on day 1 (entry), day 4, day 10 and day 21. Oro-pharyngeal swabs, and approximately 25 cc of blood will be collected at each study visit for safety labs and for the evaluation of the renin-angiotensin system (RAS) system and for various blood biomarkers of inflammation, coagulation and fibrosis.

Primary Outcome Measures :
  1. Maximum clinical severity of disease [ Time Frame: Over the 21 day period of study ]
    Based on a modified World Health Organization (WHO) COVID-19 7-point ordinal scale

Secondary Outcome Measures :
  1. Incidence of treatment emergent adverse events [ Time Frame: Through study completion at day 21 of study ]
    Number of adverse events grade 2 and above utilizing the Division of AIDS Table for Grading the Severity of Adult and Pediatric Adverse Events, Version 2.0, November 2014

  2. Renin angiotensin system peptides [ Time Frame: At each study time point (day 4, day 10, day 21) ]
    Angiotensin I (AngI), AngII, Ang1-9 and Ang1-7

  3. Plasma biomarkers [ Time Frame: At each study time point (day 4, day 10, day 21) ]
    plasma biomarkers of organ function/coagulation, inflammation, leukocyte chemotaxis, tissue remodeling/fibrosis and immune exhaustion by Luminex multiplexing assays such as TNF-alpha, IL-6, CK-MB, Troponin I, Fractalkine, MCP-1, PD-1, TIMP-1
