Summary
More cases of COVID-19 pandemic are being reported daily around the world. It is highly
infectious and, over 7 million people have been infected and more than 400,000 people have
died globally till this date. Countries around the world are struggling to avoid the spread
of this pandemic.
Center for Disease Control and Prevention (CDC) confirmed that there are no approved drugs
for COVID-19 treatment. Researchers around the globe, however, are researching different
medications for COVID-19 patients, including the drug Hydroxychloroquine (HCQ), which is
mainly used for Rheumatoid Arthritis and Malaria. Not enough data was obtained yet to know
how well all of these medications are functioning. Therefore, aim to perform a randomized
placebo-controlled trial to assess the impact of these medications on COVID -19 healthcare
workers exposed while treating COVID 19 patients in Qatar to avoid causality and
comorbidities in healthcare workers.
It is considered as a weak base. Many viruses enter the host cells via endocytosis, as a
result of which they are initially taken up into an intracellular compartment that is
"typically fairly acidic" whereas; Hydroxychloroquine would alter the acidity of this
compartment, which can interfere with the ability of viruses to escape into the host cell and
start replicating. Another hypothesis on the rationale of the Antiviral activity of HCQ, is
that HCQ may also alter the ability of the virus to bind to the outside of a host cell in the
first place.
An interventional, double-blind, placebo-controlled randomized trial that will include
participants who will be healthcare workers at risks of exposure to COVID-19 while managing
patients with confirmed infection.
Study will compare the safety, efficacy and effectiveness of Post Exposure Prophylaxis (PEP)
use of HCQ in healthcare workers at risk of exposure to COVID-19 patients, in comparison to
Placebo in Qatar.
