COVID-19
Conditions
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
| Measure | Time frame | Description |
|---|---|---|
| Maximum Clinical Severity of Disease Since Entry | maximum clinical severity of disease post entry evaluated over the 21 day clinical study | We utilized the World Health Organization (WHO) COVID-19 7-point ordinal scale: 1 (not hospitalized, no limitations on activities), 2 (not hospitalized limitation on activities); 3 (hospitalized, not requiring oxygen); 4 (hospitalized and requiring oxygen); 5 (hospitalized, on non-invasive ventilation or high flow oxygen devices); 6 (hospitalized, on invasive mechanical ventilation or ECMO) and 7 (death). A symptom scale was devised to allow 'fine tuning' within the 2.0 WHO category of 'not hospitalized but limitation on activities' based on severity (no symptoms, mild, moderate, moderately severe and severe symptoms) of fever, breathing and fatigue severity scale (0 to 4 points for each factor allowing a max score of 12). A WHO scale within the '2' category was then 'fine tuned' as follows: 2.0 (\</=3 symptom points), 2.25 (4-6 symptom points), 2.5 (7-9 symptom points), and 2.75 (10-12 symptom points). |

Recruitment details
Recruitment was advertised generally via physicians and clinics connected with our research center as well as via our medical school's community relations outreach office. Because of the communicable nature of acute COVID-19 infection, the participants were screened, enrolled and underwent their study visits under a portable tent just outside our research clinic on the grounds of the medical school.
Pre-assignment details
No pre-assignment events.

Outcome results
Maximum Clinical Severity of Disease Since Entry
