Brief summary
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.
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.
Interventions

DIETARY_SUPPLEMENTMaltodextrin
Maltodextrin 600mg daily for 12 weeks (3 chewable tablets of 100mg, twice a day), for 12 weeks plus personal portection provided from the hospital.
