About this study
Official title: Bovine Lactoferrin for the Prevention of COVID-19 Infection in Physicians and Nurses in Hospitals in Lima, Peru: a Double Blinded Randomized Clinical Trial (LF-COVID)
Clinical trial in health care personnel (physicians, nurses or nurse assistants) to determine the effect of orally-administered bovine lactoferrin to prevent SARS-CoV-2 infection. Participants will be randomized to receive daily bovine lactoferrin plus standard measures during 12 weeks or placebo (maltodextrine) for the prevention of SARS-CoV-2. The target enrollment is 336 participants. Each study participant will be monitored twice a week for symptoms of COVID-19 and if symptoms occur, a RT-PCR will be performed. Additionally, we will evaluate asymptomatic infections, by measuring SARS-CoV-2 serology every 4 weeks.
Read the detailed description
The SARS-CoV-2 infection has affected more than 100 countries around the world being classified as a pandemic by the World Health Organization. Health care providers are at high risk to become infected with the SARS-CoV-2 due to their continuous exposition to infected patients. Multiple strategies are being developed as potential prophylactic regimens, however to date (4th Aug 2020) none has proven to be effective for preventing the SARS-CoV-2 infection. Lactoferrin, an iron-binding protein with multiple physiological functions (anti-microbial, anti-inflammatory, and immunomodulatory), is one of the most important proteins present in mammalian milk. It has shown to inhibit the SARS entry to target cells by inhibiting the union of the SARS-CoV-2 spike protein with its receptor (ACE-II receptors), blocking the heparan sulfate proteoglycan receptor and it decreases the viral load of SARS-CoV-2 infecting culture cells in in vitro models. The study hypothesis is that lactoferrin given as a daily oral food supplement to health care workers will decrease the frequency of SARS-CoV-2 infection. The investigators will conduct a randomized double blinded placebo control clinical trial in physicians, nurses and nurse assistants who work in areas of care for patients with COVID-19 (emergency, hospitalization, and Intensive Care Unit) in hospitals in Lima, Peru, to determine the effect of bovine lactoferrin on the prevention of COVID-19 infection.

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing Bovine Lactoferrin and Maltodextrin in people with SARS-CoV-2, run by Universidad Peruana Cayetano Heredia at 2 sites in Peru.
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 4 inclusion and 6 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 9 Dec 2021. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 2 sites in Peru. 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. Some participants in this study may receive a placebo. 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
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: The study was interrupted due to the arrival and distribution of the vaccine to hospital workers in Peru). 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?
Number of COVID-19 infections during the 12 weeks of intervention (time frame: Twelve weeks). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT04526821, which also lists 8 linked publications.
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 9 Dec 2021.
