About this study

Official title: Chemoprophylaxis of SARS-CoV-2 Infection (COVID-19) in Exposed Healthcare Workers : A Randomized Double-blind Placebo-controlled Clinical Trial

Since December 2019, the emergence of a new coronavirus named SARS-Cov-2 in the city of Wuhan in China has been responsible for a major epidemic of respiratory infections, including severe pneumonia. Within weeks, COVID-19 became a pandemic.

In the absence of specific antiviral treatment, a special attention should be given to prevention. Personal protection equipments may be insufficiently protective, including in healthcare workers, a significant proportion of whom (around 4%) having been infected in the outbreaks described in China and more recently in Italy. Infection in healthcare workers could result from the contact with COVID-19 people in community or with infected colleagues or patients.

As it will take at least a year before vaccines against SARS-CoV-2 becomes available, chemoprophylaxis is an option that should be considered in this setting where prevention of SARS-CoV-2 infection in Health Care Workers.

The COVIDAXIS trial evaluates a chemoprophylaxis of SARS-CoV-2 infection in Health Care Workers. This trial is divided into two distinct studies that could start independently each with its own randomization process: COVIDAXIS 1 will study Hydroxychloroquine (HCQ) versus placebo; COVIDAXIS 2 will study Lopinavir/ritonavir (LPV/r) versus placebo.

Upon randomization healthcare workers (HCWs) involved in the management of suspected or confirmed COVID-19 cases will be assigned to one of the following 2 treatment groups:

Read the detailed description

The study COVIDAXIS 1(Hydroxychloroquine (HCQ) versus placebo) will be realized on 600 participants and will be implemented first in as many centers as possible.

Upon randomization, with 1:1 allocation ratio, healthcare workers involved in the management of suspected or confirmed COVID-19 cases will be assigned to one of the following 2 treatment groups:

  • Group 1.1: HCQ 200 mg : 2 tablets on the evening at Day 1 and 2 tablets on the morning at Day 2 and 1 tablet once daily afterwards
  • Group 1.2: Placebo of HCQ, 2 tablets on the evening at Day 1 and 2 tablets on the morning at Day 2 and 1 tablet once daily afterwards.

The COVIDAXIS 2 (Lopinavir/ritonavir (LPV/r) versus placebo will be realized on 600 participants and will be implemented in already participating and newer centers in a second step (when LPV/r becomes available).

Upon randomization, with 1:1 allocation ratio, healthcare workers involved in the management of suspected or confirmed COVID-19 cases will be assigned to one of the following 2 treatment groups:

  • Group 2.1: LPV/r 200/50 mg : 2 tablets twice daily
  • Group 2.2: Placebo of LPV/r, 2 tablets twice daily

Participants will receive the randomized treatment for 2 months and will be followed upon a 2.5 months period.

NB: there is no randomization procedure for participant inclusion in either COVIDAXIS 1 or COVIDAXIS 2

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Occurrence of an symptomatic or asymptomatic SARS-CoV-2 infection among healthcare workers (HCWs)

    An infection by SARS-CoV-2 is defined by either:

    • a positive specific Reverse Transcription - Polymerase Chain Reaction (RT-PCR) on periodic systematic nasopharyngeal swab during follow-up OR
    • a positive specific RT-PCR on a respiratory sample in case of onset of symptoms consistent with COVID-19 during follow-up OR
    • a seroconversion to SARS-CoV-2 after randomization.

    Measured: Up to 2.5 months

Secondary outcomes (7)
  1. Evaluation of the occurrence of adverse events in each arm,

    Number of adverse events expected or unexpected, related and unrelated to the treatment, notably grades 2, 3 and 4 (moderate, severe and lifethreatening, according to the Adverse National Cancer Institute Common Terminology Criteria for Adverse Events, version 5.0) in each arm.

    Measured: Up to 2.5 months

  2. Evaluation of the discontinuation rates of the investigational drug in each arm,

    Number of treatment discontinuations in each arm

    Measured: Up to 2 months

  3. Evaluation of the adherence of participants to study drug,

    Treatment adherence rate will be assessed by:

    • measurement of LPV and HCQ plasma concentrations using LC-MS/MS or LC-Fluorimetric detection
    • the count of returned drugs at each visit.

    Measured: Up to 2 months

  4. Evaluation of the incidence of symptomatic cases of SARS-CoV-2 infection in each arm,

    Number of incident cases of symptomatic SARS-CoV-2 infections among HCWs in each arm.

    Symptomatic infection is defined as :

    • a positive specific RT-PCR on a respiratory or non respiratory sample OR
    • a thoracic CT scan with imaging abnormalities consistent with COVID-19.

    These investigations being performed in case of signs/symptoms consistent with COVID-19 during follow-up.

    Measured: Up to 2.5 months

  5. Evaluation of the incidence of asymptomatic cases of SARS-CoV-2 infection in each arm

    Number of incident cases of asymptomatic SARS-CoV-2 infection among HCWs in each randomization arm.

    Asymptomatic infection is defined as :

    • a positive specific RT-PCR on periodic systematic nasopharyngeal swab during clinical follow-up without consistent clinical signs/symptoms during follow-up OR
    • as seroconversion to SARS-CoV-2 between start and end of the study in HCWs that did not reported any consistent clinical symptoms during follow-up

    Measured: Up to 2.5 months

  6. Evaluation of the incidence of severe cases of SARS-CoV-2 infection in each arm.

    Number of incident cases of severe SARS-CoV-2 infections among HCWs in each randomization arm, defined as :

    • a positive specific RT-PCR on a respiratory sample OR
    • a thoracic CT scan with imaging abnormalities consistent with COVID-19 performed in case of onset of symptoms consistent with COVID-19 during follow-up in a participant who need to be hospitalized for respiratory distress. Respiratory distress defined as dyspnea with a respiratory frequency > 30/min, blood oxygen saturation <93%, partial pressure of arterial oxygen to fraction of inspired oxygen ratio <300 and/or lung infiltrates >50% (1).

    Measured: Up to 2.5 months

  7. corrected QT interval (ms)

    Safety. Electrocardiogram (ECG)

    Measured: At baseline, at D2 (only for COVIDAXIS 1) and every week up to 2 months.

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Hydroxychloroquine and Lopinavir and ritonavir in people with COVID-19, run by Centre Hospitalier Universitaire de Saint Etienne at 9 sites in France.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 7 inclusion and 23 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: stopped early, as of the sponsor's last update on 1 Mar 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 9 sites in France. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study was stopped early (reason given: French authority's decision). Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Occurrence of an symptomatic or asymptomatic SARS-CoV-2 infection among healthcare workers (HCWs) (time frame: Up to 2.5 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 1 Mar 2023.
