Brief Summary:

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).


Condition or disease Intervention/treatment Phase
COVID19 Hydroxychloroquine Prophylaxis Treatment SARS-CoV-2 Drug: Hydroxychloroquine Phase 2

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.

Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. the proportion of subjects of Group 1 who become symptomatic and/or swab positive in each arm within 1 month from randomization. [ Time Frame: within 1 month from randomization ]
    Group 1:The primary endpoint/outcome measure is the proportion of subjects of Group 1 who become symptomatic and/or swab positive in each arm within 1 month from randomization.

  2. the proportion of subjects of Group 2 who become swab negative in each arm within 14 days from randomization. [ Time Frame: within 14 days from randomization ]
    Group 2: The primary endpoint/outcome measure is the proportion of subjects of Group 2 who become swab negative in each arm within 14 days from randomization.


Secondary Outcome Measures :
  1. The proportion of subjects with positive swabs in Group 1 within 1 month from randomization in both arms [ Time Frame: within 1 month from randomization ]
    The proportion of subjects with positive swabs in randomized population of SARS-CoV-2-exposed subjects ( Group 1) within 1 month from randomization in both arms

  2. The proportion of subjects of Group 1 who become symptomatic in each arm within 1 month from randomization [ Time Frame: within 1 month from randomization ]
    The proportion of subjects of Group 1 who become symptomatic in each arm within 1 month from randomization, in subgroup population identified by stratification factors, class of age and gender.

  3. The proportion of subjects of Group 2 who become swab negative in each arm within 14 days from randomization. [ Time Frame: within 14 days from randomization ]
    The proportion of subjects of Group 2 who become swab negative in each arm within 14 days from randomization, in subgroup population identified by stratification factors, class of age and gender.

  4. The proportion of subjects of Group 2 who become swab negative in each arm within 1 month from randomization in overall population and in subgroup population [ Time Frame: within 1 month from randomization ]
    The proportion of subjects of Group 2 who become swab negative in each arm within 1 month from randomization in overall population and in subgroup population identified by stratification factors, class of age and gender.

  5. Absolute and relative frequencies of Serious Adverse Events [ Time Frame: up to 10 months ]
    Absolute and relative frequencies of Serious Adverse Events (CTCAE version 5.0) in both arms for the Group 1 and Group 2.

  6. Variation in Quality of Life scores in different time points [ Time Frame: up to 10 months ]
    Variation in Quality of Life scores EQ-5D-5L (EQ-5D descriptive system with 5 severity levels from better to worse, and the EQ visual analogue scale (EQ VAS, scale from 100 to 0, high is better) in different time points (weekly) respect to baseline values in both Group 1 and Group 2 populations.
