The overarching goal of the Master Protocol is to find effective strategies for inpatient management of patients with COVID-19. Therapeutic goals for patients hospitalized for COVID-19 include hastening recovery and preventing progression to critical illness, multiorgan failure, or death. Our objective is to determine whether modulating the host tissue response with agents targeting the RAAS improves clinical outcomes among patients with COVID-19.
Potential agents to investigate on this platform include TXA127 and TRV027. Both have potential beneficial effects on the RAAS system in COVID-19. We postulate that SARS-CoV-2 spike protein interaction with the ACE2 receptor leads to unchecked activity of AngII, and RAAS-targeting therapies will counterbalance pathologic RAAS effects. We will evaluate the efficacy of TXA127 and TRV027 in restoring RAAS balance.

This is a low-interventional cohort study to determine cardiac and non-cardiac long-term outcomes of persons <21 years of age with myocarditis/pericarditis after the administration of COMIRNATY, compared with similarly aged persons with myocarditis/pericarditis associated with COVID-19, including MIS-C.
