Brief Summary:
The purpose of this study is to assess the efficacy and safety of prazosin to prevent cytokine storm syndrome and severe complications in hospitalized patients with Coronavirus disease 2019 (COVID-19).
Detailed Description:
In Coronavirus disease 2019 (COVID-19), severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) elicits an exuberant local or systemic immune response ('hyperinflammation') in the lung and other sites of viral replication, compromising organ function and leading to high morbidity and mortality. Emerging evidence suggests that a subset of patients with COVID-19 develops a cytokine storm syndrome that is associated with elevation of pro-inflammatory cytokines.
Catecholamines enhance inflammatory injury by augmenting the production of IL-6 and other cytokines through a self-amplifying feed-forward loop in immune cells that requires alpha-1 adrenergic receptor (⍺1-AR) signaling. The ⍺1-AR antagonist prazosin prevents cytokine storm and markedly increased survival following inflammatory stimuli in preclinical models. In a retrospective study of outcomes in acute respiratory distress syndrome or pneumonia, patients who were taking ⍺1-AR antagonists had significantly lower probability of needing invasive mechanical ventilation and dying in the hospital compared to non-users.
Prazosin may blunt surges in catecholamines and self-amplifying cytokine production (including interleukin 6) and, as an early preemptive therapy in patients prior to disease progression, may prevent cytokine storm syndrome and severe complications of COVID-19.
In this study, patients with positive SARS-CoV-2 testing who are hospitalized (but are not requiring more than 4 liters/minute of supplemental oxygen by nasal cannula) will be screened for eligibility. Patients who provide informed consent and meet eligibility requirements will be randomized in a 1:1 ratio to receive either prazosin or standard of care. Participants randomized to the study drug will receive prazosin for 28 days and all patients will be followed for a total of 60 days to capture outcomes.
