Summary

This is a PILOT STUDY, a Phase III double-blind, randomized, placebo-controlled clinical study in which we assess the clinical effect of the prophylactic administration of hydroxychloroquine vs. placebo to healthcare workers working at our University Hospital (HUN). Participants in each arm (n = 43) will be administered with a unique loading dose of 800 mg of hydroxychloroquine the first day followed by 400 mg/week for 90 days. The population to be studied (uninfected healthcare personnel) will be highly exposed to SARS-CoV-2 infection. An active search should be made for individuals who become infected while participating in the study, hence, once the informed consent form is signed, the molecular test for the diagnosis of SARS-CoV-2 infection by RT-PCR will be carried out every 4 days in order to determine as closely as possible the moment the participant becomes positive. The results of the diagnostic RT-qPCR tests will be confronted with: (i) the results of immune monitoring of at least 30 immunological parameters in leukocytes and in plasma (levels of selected cytokines and chemokines analyzed by automated flow cytometry software and (ii) the daily recording of data for the presence or absence of signs and symptoms associated with SARS-Cov-2 infection. For the recording of immune monitoring 20mL blood samples will be taken at eight-time points throughout the 90 days of the stud.
