This requires a coordinated, effective and immediate action on the part of governments, companies, academic entities and even at the individual level.\n\nIn the search for new therapeutic and prevention alternatives, the application of hypochlorous acid (HClO) to the nasal mucosa is proposed, a broad-spectrum and fast-acting antimicrobial solution, whose safety has been proven in preclinical trials. The efficacy of HClO has been tested against enveloped and non-enveloped viruses, reducing virus particles without affecting human cells. This solution could contribute to reducing the viral load and the risk of contamination of patients and professionals. This could have an impact on controlling the COVID-19 pandemic.', 'detailedDescription': 'Hypochlorous acid (HClO) is a powerful antimicrobial and antiviral used for the control of various infections, repair and washing of surgical wounds, as well as for disinfection of surfaces. In vivo, it is synthesized by the cells of the immune system for the control of pathogens during phagocytosis and has been synthesized and stabilized for use in different entities.\n\nThe therapeutic uses of HClO began in the First World War with the studies of Alexis Carrel and Henry Dakin who obtained a buffered sodium hypochlorite solution (Dakin\'s solution) which generated ideal concentrations of HClO, using it successfully in washing and treatment of wounds without presenting any damage or undesired effect on the patient\'s tissues. In 1993, the HClO molecule was stabilized, popularizing its use for the control of predominantly skin infections, treatment of chronic ulcers, closure and cleaning of wounds, management of burned patients, and disinfection of surfaces.\n\nBiologically, it is part of the reactive oxygen species (ROS) synthesized by cells of the immune system (Neutrophils and Macrophages) during an immunological process known as "respiratory burst", during phagocytosis of antigens in reaction with the enzyme myeloperoxidase (MPO), hydrogen peroxide (H2O2) and a chlorine ion. Safety profiles in in vivo models have driven our initiative to use Stabilized Hypochlorous Acid (S-HClO), as an early therapeutic option in patients with SARS-Cov-2 infection or in close contact with COVID-193 positive patients.\n\nCalderon et al and carried out the evaluation of the antimicrobial effect of HClO on potentially pathogenic microorganisms of the oral cavity. The study reports that hypochlorous acid achieved bacterial inhibition of 99.9% at a concentration of 0.05% and a pH of 5.2 per minute of action for different types of bacteria and for infectious microorganisms. Virological tests have also been performed on feline calcivirus (Ebola-like virus), rotavirus, AH1N1, adenovirus and SARS, found to be highly effective after 1 minute of application.\n\nIn the face of the COVID-19 pandemic, effective and early treatments are being sought to help prevent the dissipation of the virus (disinfection of surfaces), to neutralize the virus at an early stage when it is lodged in the upper respiratory tract and nose, since this is the Probable route of infection of the ethmoid lamina and later causing viral encephalopathy and treatment of patients with bronchial infection by this virus, decreasing the viral load and causing destruction of the virus. There are reports of the use of HClO in the nasal mucosa in studies in humans, reporting safety and effectiveness, both in adults and in children, which leads us to propose the application of said nasal spray solution, as a prophylaxis in health personnel with a high risk of infection by SARS-CoV-2.\n\nA RCT with the use S-HClO as a prevention treatment for the infection by SARS-CoV-2 in health professionals is proposed.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'maximumAge': '80 Years', 'minimumAge': '18 Years', 'healthyVolunteers': True, 'eligibilityCriteria': "Inclusion Criteria:\n\n* Specialist physicians, resident physicians, medical students, and nursing personnel who work at the San Ignacio University Hospital.\n* Subjects of any sex over 18 years of age who work as health care personnel, in care services that care for patients with a suspected or confirmed diagnosis of COVID-19 and who are active during the study recruitment.\n* That they have not presented general symptoms such as malaise, fever, cough, dyspnea or muscle pain during the last 7 days.\n* Subjects negative to the antigen test for COVID-19.\n\nExclusion Criteria:\n\n* Subjects considered as a resolved case of COVID-19 infection, according to guidelines from the Colombian National Institute of Health.\n* Health personnel with social distancing due to close contact without personal protective equipment with patients confirmed to be infected or taking any medication as a possible prophylaxis for COVID-19 (example: chloroquine, hydroxychloroquine, azithromycin)\n* Health workers who have permits or temporary withdrawal from their hospital work for more than one week during the month of the study.\n* Some type of allergy to chlorinated agents or hypersensitivity to HClO\n* Known diagnosis of upper airway respiratory disease where COVID-19 such as the common cold, sinusitis, pharyngitis, laryngotracheitis and epiglottitis or lower such as bronchiolitis, pneumonia, and mixed conditions have been ruled out.\n* Previous COVID19 infection determined by positive PCR or positive serum antibody titers.\n* Any condition that in the principal investigator's discretion renders the subject ineligible to participate in the study."}, 'identificationModule': {'nctId': 'NCT04684550', 'briefTitle': 'Use of Hypochlorous Acid as Prophylaxis in Health Personnel at High Risk of Infection by SARS-CoV 2 (COVID19)', 'organization': {'class': 'OTHER', 'fullName': 'Hospital Universitario San Ignacio'}, 'officialTitle': 'Randomized Controlled Clinical Study (RCT) Phase 3 of the Safety and Efficacy of Hypochlorous Acid in the Prophylaxis of Healthcare Personnel at High Risk of Infection by SARS-CoV2 (COVID19) Versus Placebo', 'orgStudyIdInfo': {'id': 'FM-CIE-0824-20'}}, 'armsInterventionsModule': {'armGroups': [{'type': 'PLACEBO_COMPARATOR', 'label': 'Placebo', 'description': 'Health personnel who work in places of greater risk (hospitals and primary level consultation) with conventional protection elements added to the application of 2 nasal puff every 8 hours of a nasal spray containing 0.9% SSN (placebo) and gargles (SSN 0.9%).', 'interventionNames': ['Drug: Placebo']}, {'type': 'EXPERIMENTAL', 'label': 'Experimental', 'description': 'Health personnel who work in higher risk places (hospitals and primary level consultation) with conventional protection elements added to the application of 2 puffs and gargles every 8 hours of a solution with low concentrations of S-HCLO (3-5 ppm).', 'interventionNames': ['Drug: Stabilized hypochlorous acid']}], 'interventions': [{'name': 'Stabilized hypochlorous acid', 'type': 'DRUG', 'description': 'Application of 2 puffs and gargles every 8 hours of a solution with low concentrations of S-HCLO (3-5 ppm).', 'armGroupLabels': ['Experimental']}, {'name': 'Placebo', 'type': 'DRUG', 'description': 'Application of 2 puffs and gargles every 8 hours of a solution with low concentrations of S-HCLO (3-5 ppm).', 'armGroupLabels': ['Placebo']}]}, 'contactsLocationsModule': {'overallOfficials': [{'name': 'Juan Zambrano, MD.
