COVID-19
About this trial
This is an interventional treatment trial for COVID-19 focused on measuring SARS-CoV-2, Coronavirus disease 2019, COVID-19, Cytokine Storm Syndrome, Acute Respiratory Distress Syndrome, Prazosin, Alpha-1 receptor antagonist
Eligibility Criteria
Inclusion Criteria:
- Subjects must be 45 years of age or older
- Provision of informed consent
- Subjects who tested positive for SARS-CoV-2 AND have clinical symptoms of COVID-19* AND have been hospitalized, but are not requiring more than 4 liters/minute of supplemental oxygen by nasal cannula and are not requiring ICU/CCU-level care at time of enrollment
(*)Acute respiratory tract infection (sudden onset of at least one of the following: fever, chills, sore throat, myalgia, diarrhea, cough, or shortness of breath) AND with no other etiology that fully explains the clinical presentation
Exclusion Criteria:
- Female subjects who identify as pregnant, self-reported positive pregnancy testing, or who are breastfeeding during the study period
- Age >85 years
- Known history of known orthostatic hypotension, unexplained history of syncope, postural orthostatic tachycardia syndrome (POTS), neurally-mediated hypotension, heart failure, myocardial infarction, stable or unstable angina, history of coronary artery bypass surgery, stroke, carotid artery disease, or moderate to severe mitral or aortic stenosis
- Current use of tocilizumab, sarilumab, siltuximab, lopinavir/ritonavir, remdesivir, favipiravir, alpha-blockers, combined alpha/beta blockers (carvedilol, labetalol), sotalol, clonidine, phosphodiesterase type 5 inhibitors, asenapine, or alpha-methyldopa
- Need for vasopressors, inotropes, or intra-aortic balloon pump at time of enrollment
- Allergy or intolerance to quinazolines (including prazosin)
- Requires oxygen supplementation beyond 4 liters of oxygen/minute per nasal cannula at time of enrollment (i.e. not requiring oxygenation by non-rebreather, high-flow nasal cannula, CPAP/BiPAP, or invasive mechanical ventilation)
- Patients who are in the custody of state or federal entities (prisoners)
Sites / Locations
- Johns Hopkins Hospital
Arms of the Study
Arm 1
Arm 2
Experimental
Active Comparator
Prazosin
Standard of care
Prazosin 1mg given to observe if medication is tolerated or if signs or symptoms of hypotension develop (e.g. dizziness, lightheadedness). If the patient remains asymptomatic and BP >110/60 mmHg, prazosin is continued at 1mg every 8 hours (q8h). Day 3: If the patient remains asymptomatic and BP >110/60 mmHg, increase dose to 2mg q8h. Day 6: If the patient remains asymptomatic and BP >110/60 mmHg, increase dose to 5mg q8h. If the BP is <100/60 mmHg at any time, the next dose should be held, and patient continues with the highest previously tolerated dose 8 hours later. If the patient did not tolerate dose escalation to 5mg q8h, one attempt is made to increase dose to 3mg q8h. If this is not tolerated, the patient continues with the highest previously tolerated dose 8 hours later. If BP monitoring is not available, repeated occurrences of postural dizziness should trigger drug dose reduction or BP monitoring.
Subjects randomized to this arm will receive standard of care.
