Brief Title  ICMJE Primary Prevention of Infection by COVID-19 in Health Providers
Official Title  ICMJE Scheme of Primary Prevention of Infection by COVID-19, in Health Providers: Phase II Controlled Clinical Trial, to be Carried Out in Medellín-Antioquia
Brief Summary

Introduction: The SARS Co-2 contagious rate is high (Ro: 2.0-3.0). The infection is aggressive with high pathogenicity. Global confinement impacts all social and economic fields of human activity. Clinical behavior exceeds the capabilities of public health care. With the initial information on the pandemic, it is estimated that 20% of health personnel in direct contact with patients can acquire the disease, despite preventive self-care. The molecular relationship of COVID-19 with the subject's ACE2 protein encourages the virus to enter the host cell, and initiates replication and the immune response, causing an imbalance generating an immunological storm of cytokines, with serious damage to the host.

Objective: It is proposed to supply a combined scheme of two compounds by oropharyngeal spray that capture the virus before entering the target cell and orally administer immunomodulatory compounds that regulate the inflammatory response released by the virus, in order to improve the antiviral response.

Methodology: A controlled, parallel design, triple blind, phase II clinical trial will be conducted with four study groups to compare the active compounds (oropharyngeal spray and capsule) with placebo.

Discussion: With the application of the combined scheme of two compounds, a 75% reduction in infection is expected in health providers in direct contact with COVID patients.

Detailed Description

RESEARCH QUESTION: Can the oropharyngeal spray of a viral blocking compound in conjunction with the provision of an immunostimulant compound, reduce the infection proportion by 2/3

BENEFITS OF EACH INTERVENTION.

INTERVENTION 1: The compound for oropharyngeal spray made out of three bioactive substances combined that are: allicin, eugenol and quercetin, as soluble recruiters of the virus at its main entry point, the upper respiratory tract or oropharyngeal region. There, these substances, which have high molecular homology to the sites or epitopes of the ACE-2 receptor, will act as soluble receptor for the virus, and will be a preventive barrier for its entrance and contact with the native receptor, ACE-2; in this way, it is intended to reduce the possibility of infection by COVID-19, protecting at the level of the oropharyngeal mucosa from the direct inoculation of the virus.

INTERVENTION 2: The immunostimulant compound will be used to potentiate the immune response of the subject, measured by the reduction in the risk of infection, as a complement to the effect of the soluble substances, homologous to the ACE-2 receptor, administered by oropharyngeal spray.

RESEARCH HYPOTHESIS: In health care providers in the front line of care of suspicious cases or patients with COVID-19, the combined use of the interventions in question (oropharyngeal spray of a soluble compound that captures the virus, in addition to the ingestion of an immunostimulant compound), in comparison to the non-administration of either (Placebo), reduces the risk of infection with COVID-19, expressed as a negative result in IgM, IgG; and in those who undergo seroconversion, the greater proportion will have a mild to moderate clinical presentation.

PRIMARY OBJECTIVE: To establish the efficacy of the combined use of the oropharyngeal spray of a soluble compound that captures the virus, in addition to the ingestion of an immunostimulant compound, in comparison with placebo, on the reduction of the risk of infection with COVID, indicated by the negative result in the measurement of COVID-19 immunoglobulins by 30 days of starting the combined therapy. To establish the safety of the study products with evaluation of the expected and unexpected adverse events encountered during the treatment phase of the intervention (30 days since entering the project).

SECONDARY OBJECTIVE: To establish the efficacy of the combined use of the of the oropharyngeal spray of a soluble compound that captures the virus, in addition to the ingestion of an immunostimulant compound, in comparison with placebo, on the reduction of the risk of infection with COVID, indicated by the clinical response to the disease, defined in three variations, mild to moderate: onset of fever, myalgias and cough without dyspnea; severe: fever, myalgias, cough and dyspnea that requires inpatient care; and critical: all of the above in addition to ventilatory support in the ICU.

EXPLORATORY OBJECTIVES: To explore the efficacy of the combined use of the oropharyngeal spray of a soluble compound that captures the virus, in addition to the ingestion of an immunostimulant compound, on the reduction of the development of symptoms such as fever, cough, dyspnea, myalgias, or ventilatory support in the ICU, 15 days after finishing the treatment scheme. To explore the independent efficacy of each intervention (oropharyngeal spray of a soluble compound that captures the virus, or the ingestion of an immunostimulant compound), compared with placebo, on the reduction in the risk of infection with COVID, given by the negative result of IgG, IgM; and the decrease in the risk of symptoms such as fever, cough, dyspnea, myalgias, or ventilatory support in the ICU, 15 days after finishing the treatment scheme.

FIELD OF STUDY: Health care centers in the city of Medellín, where suspected cases and patients with COVID-19 are being treated. A list with the participating centers will be drawn up.

INTERVENTIONS.

ACTIVE PRINCIPLE:

Intervention 1: Preparation in a liquid solution to be used for oropharyngeal spray, composed of natural bioactive substances of routine use in humans, that feature homologous molecular structures to the native viral receptor.

Intervention 2: Preparation in a solid pharmaceutical presentation for oral administration in a capsule form (inside a small gelatin container), that contains the bioactive compounds that have demonstrated modulation of the inflammatory response recognized at the moment in the immune activation against the virus.

PLACEBO: Formulations without active components in the same pharmaceutical form as the former (intervention 1 and intervention 2). They will be presented with the same physical characteristics as the placebos, such as: shape, form, color, taste, smell, consistency, printed indications, weight, surface details, internal and external; in this way, the principal of concealment is guaranteed. They must be used under the following indications.

Intervention 1: Two oropharyngeal sprays of the compound, every 4 hours, during the day.

Intervention 2: Administering 1 capsule by mouth of the immunostimulant, every twelve hours. Dosing of the substances in intervention 1 follows the described pharmacological characteristics, that guarantee its permanence in the oral mucosa to protect the entry pathway of the virus into the organism (Oropharynx). The dosage of the oral compounds was defined according to recommendations of the WHO for the modulation of the immune response (capsules). In the randomization visit V1, each participant will be assigned a treatment scheme, composed of intervention 1 and intervention 2, in sufficient quantity for the duration of the study. The pharmaceutical service will dispense the code of the scheme, following a sequential order, indicated in an allocation listing of the schemes in site. Each treatment scheme is labeled with a unique code that identifies it, and it contains: One (1) device for oropharyngeal spray, with capacity for 200 applications. One (1) bottle with 90 capsules (oral). In the subsequent visits the adherence to the dispensed schemes will be verified. The frequency of use will be checked, and dosing omissions will be registered by frequency (1 dose, once a week, more than once a week).

Masking Description:
Once the participant has given its informed consent, and the research team has verified the fulfillment of the inclusion criteria, the prospect receives a text message, to be directed to the pharmaceutical service. The numbered scheme will be dispensed with the code of the intervention, following the order from the allocation listing, provided by the CTCC. The head of the pharmaceutical service will register the date and time of the first dose. He will provide indications for the use, handling and conservation of the products. Warning signs and symptoms and instructions for communication with the research team to address any concern the subject may have will be reviewed. He will remind the subject to avoid its damage or loss. He will give the participant instructions to return the container and surpluses of the products at the end of the trial (day 30), he will point out that they are for personal use only and that they cannot be shared.
