Descriptive Information

• Brief Title: Treatment of COVID-19 Cases and Chemoprophylaxis of Contacts as Prevention
• Official Title: Treatment of Non-severe Confirmed Cases of COVID-19 and Chemoprophylaxis of Their Contacts as Prevention Strategy: a Cluster Randomized Clinical Trial (PEP CoV-2 Study)
• Brief Summary: This study is a research project to evaluate the efficacy of hydroxychloroquine for post-exposure prophylaxis and early treatment of Covid-19. The intervention entails administering prophylactic hydroxychloroquine to all contacts (Study 1) and treating non severe confirmed cases with hydroxychloroquine (Study 2).

Detailed Description

Hydroxychloroquine (HCQ) is a drug that has been extensively used for the prevention of malaria. HCQ showed excellent in vitro results and strong antiviral effects on SARS-CoV-2 infection of primate cells at low concentration. Empirical data for the efficacy of HCQ in hospitalized Covid-19 patients became available after the start of this study; HCQ administration did not result in a significantly higher PCR negative conversion in a RCT including 150 patients and there was no reduction in the risk of death/intubation in two large observational studies.

Study 1 -We investigated the efficacy and safety of HCQ to prevent secondary SARS-CoV-2 infection and Covid-19 disease in contacts exposed to a PCR-positive Covid-19 case during.

Study 2- We also conducted a study to test the hypothesis that HCQ treatment would be more efficacious than no-treatment for patients with mild Covid-19.

Initially, the protocol included the use of combined treatment with a HIV protease inhibidor (cobicistat-boosted darunavir) for cases (study 2), but it was adapted to HCQ alone after the recommendation of the pharmaceutical company not to use DRVc for the treatment of Covid-19 due to lack of activity in-vitro.

• Condition: COVID-19

Intervention

• Drug: Treatment and prophylaxis

  Cases will be offered a therapeutic regimen hydroxychloroquine (200mg tablets) 800mg on day 1, and 400mg on days 2-7

  Contacts will be offered a prophylactic regimen of hydroxychloroquine (200mg tablets) 800mg on day 1, and 400mg on days 2-7.

  Isolation of patient and contact tracing as per national guidelines.

  Intervention: Other: Standard Public Health measures
• Experimental: Testing, treatment and prophylaxis of SARS-CoV-2

  Study 1- Contacts receive Hydroxychloroquine prophylaxis. Contacts will complete a survey collecting demographic, epidemiological and clinical and provides a swab for RT-PCR testing at baseline and day 14.

  Study 2- Index case receives Hydroxychloroquine. Index case completes a survey collecting demographic, epidemiological and clinical data and provides a swab for RT-PCR testing at baseline and on days 3, and 7.
