This is a multicenter, phase 4 prospective, single-cohort study in adult male and female volunteers hospitalized with COVID-19. Baseline nasopharyngeal swabs will be performed on all individuals. Halodine Nasal Antiseptic will then be applied to the anterior nares. Serial nasopharyngeal samples will then be collected at specified time points after the application. All samples will be tested for SARS-CoV-2 by real-time reverse transcription (rRT)-PCR assay.
Povidone iodine (PVP-I) is a well-known broad spectrum, resistance free antimicrobial agent that has a long history of safe and effective use. Halodine Nasal Antiseptic is formulated for topical application PVP-I to nasal passages, and has demonstrated effectiveness against SARS-COV-2 in vitro - 99.99% inactivation within 15 seconds. This study will evaluate the ability of Halodine Nasal Antiseptic to impact SARS-CoV-2 in vivo.
