• Conditions: COVID-19
• Interventions: Drug: HCQ & AZ

• Registration Number: NCT04354597
• Lead Sponsor: King Hussein Cancer Center

Brief Summary

The main objective of this study is to assess the efficacy of the combination hydroxychloroquine and Azithromycin (HCQ and AZ) in reducing the infection risk among health care professionals in direct contact with COVID-19 patients.

Detailed Description

Exceptional efforts have been paid globally to apply the latest and most effective means of universal standard precautions throughout the settings facing COVID-19 crisis, and this is led by health care providers who are more vulnerable and have a higher risk of getting the infection (8.3% in Italy) and a higher rate of complications and mortality with some reports suggesting high mortality among these individuals.

While several clinical trials are underway across the globe to examine the effect of chloroquine at the moment, the number of COVID-19 cases is still on the rise and health care workers are facing a very high risk of getting the infection. In this study, we aim to study prophylactic efficacy of the combination (HCQ and AZ) among health care professionals in a 16 weeks period.

Arm && Interventions

Group	Intervention	Description
Study Arm A (HCQ & AZ)	HCQ & AZ	Subjects will receive weekly HCQ 400mg X 1 Day PO and AZ 500mg PO X 3 Days; weekly for 16 weeks.

Primary Outcome Measures

Name	Time	Method
Effect of HCQ and AZ in preventing infection with COVID-19 among healthcare workers working with COVID-19 patients	4 Months	Compare the proportion of participants who have RT-PCR confirmed infection with SARS-CoV-2 in both arms during the study period, measured by negative PCR test for SARS COV-2 virus

Secondary Outcome Measures

Name	Time	Method
Safety of HCQ and AZ	4 Months	Solicited and unsolicited adverse events in participants receiving HCQ+AZ during the study period, measured by the incidence of AEs in both arms. (The difference in type, number, and intensity)
Oxygen requirement	4 Months	The proportion of participants who require oxygen therapy for any indication during the study period in both arms, measured by the requirement for O2 or not in both arms.
ICU admission	4 Months	The proportion of participants who need ICU admission for any reason during the study period in both arms, measured by the incidence of ICU admission in both arms.
Mortality rate	4 Months	The proportion of participants who die of any cause during the study period in both arms, measured by the incidence of death in both arms.
