Clinical Trial Summary

This is a randomised, multi-center, open label, adaptive, exploratory trial to assess the efficacy of two different drug regimens in terms of preventing symptomatic COVID-19 disease in healthcare workers at high risk of exposure to SARS-CoV-2. The trial will compare two different experimental medication arms to the control arm comprising the use of standard personal protective equipment (PPE) with no additional pharmacological intervention.


Clinical Trial Description

This is a randomised, multi-center, open label, adaptive, exploratory trial to assess the efficacy of two different drug regimens in terms of preventing symptomatic COVID-19 disease in healthcare workers at high risk of exposure to SARS-CoV-2. The trial will compare two different experimental medication arms to the control arm comprising the use of standard personal protective equipment (PPE) with no additional pharmacological intervention. Volunteers will be recruited from participating institutions and community healthcare workers (CHWs) that are responsible for collecting swabs for PCR detection of SARS-CoV-2. Up to 1950 (or 2130 pending funding) eligible participants will be randomised in a 1:1:1 ratio to one of the investigational arms. Participants will be followed until 65 PCR and serology-confirmed, SARS-CoV-2 infections are identified in the control arm (or 165 in the entire study cohort). For each episode of PCR-confirmed COVID-19 disease, data on self-reported symptoms (modified Flu-PRO) and their duration, and an investigator-assessed severity score (WHO Ordinal Scale for Clinical Improvement) will be recorded. Data on self-reported symptoms and duration will also be collected for other all-cause acute respiratory illnesses. Safety and tolerability of each arm will be assessed through adverse event reporting. Participants who develop COVID-19 disease will have their IMP discontinued but will be followed up in the study until the completion of the trial, where possible. Multiple, discrete occurrences of COVID-19 disease could therefore be identified in a single participant. Additional arms may be added, or existing ones substituted, should new potential agents be identified or other combinations for prophylaxis be proposed. A formal amendment will be documented should this be considered. ;
