Protect: Study With Hydroxychloroquine for Prevention and Early Phase Treatment of Coronavirus Disease (COVID-19) (PROTECT)
PROTECT: A Randomized Study With Hydroxychloroquine Versus Observational Support for Prevention or Early Phase Treatment of Coronavirus Disease (COVID-19)
This is a Italian, superiority, open label cluster-randomised, interventional clinical trial aimed at assessing whether the treatment with Hydroxychloroquine can reduce the percentage of symptomatic subjects compared to observation only in household members/contacts of COVID-19 patients (Group 1) and if the treatment with Hydroxychloroquine could be introduced in early phase COVID-19 population (Group 2).
The participants will be randomised to receive either:
Arm A) hydroxychloroquine vs Arm B) Observation (2:1 randomisation).

Detailed Description
This is an open label, superiority, cluster-randomized Italian interventional clinical trial, evaluating the role of Hydroxychloroquine versus observation only in preventing infection to COVID-19 or treating early phase COVID-19 patients.
Each index case is randomised to either Arm A: Hydroxychloroquine or Arm B: observation in a 2:1 ratio on an open label basis. Participants in the same cluster receive the same intervention.
Study population is constituted by:
Group 1: Severe Acute Respiratory Syndrome (SARS) - Corona Virus (CoV)-2-exposed subjects , as household members/contacts of COVID-19 patients.
Group 2: Patients with COVID-19 asymptomatic or paucisymptomatic in home situation.
