Brief summary

Hypromellose-based nasal spray solution containing human IgG1 anti-SARS-CoV-2 antibody cocktail is a medical device innovated to provide the dual-action physical barrier on nasal mucosa that aids the natural defence in which the mucus layer is fortified by a steric barrier-forming agent HPMC and invading viral particles of all major SARS-CoV-2 VOCs, including Delta and Omicron, are locally trapped and blocked from entering the cells by the highly-specific human IgG1 anti-SARS-CoV-2 monoclonal antibody cocktail.

Detailed description

The transmission of SARS-CoV-2 through inhalation results in the nasal cavity and nasopharynx being the primary entry point of the virus and containing the highest viral load in the body during the virus incubation period. Recently, the administration of vaccines and agents via a nasal route has gained a lot of momentum because it takes advantage of the direct delivery of an agent to the site of primary infection. The local defence system, especially antibody-mediated immunity at the nasal epithelium, is crucial for COVID-19 prevention. However, people who responded to the vaccination against COVID-19 typically maintain sufficient local antibody levels in the nasal cavity for only a short period; hence a repeated boosting strategy is required to control the rate of SARS-CoV-2 breakthrough infection. In addition, the new VOCs such as Omicron are known to escape vaccine immunity; therefore, an innovative approach is needed in this unprecedented situation Hypromellose-based nasal spray solution containing human IgG1 anti-SARS-CoV-2 antibody cocktail is a medical device innovated to provide the dual-action physical barrier on nasal mucosa that aids the natural defence in which the mucus layer is fortified by a steric barrier-forming agent HPMC and invading viral particles of all major SARS-CoV-2 VOCs, including Delta and Omicron, are locally trapped and blocked from entering the cells by the highly-specific human IgG1 anti-SARS-CoV-2 monoclonal antibody cocktail.

Other

MeasureTime frameDescription
Sino-Nasal Outcome Test-22 (SNOT-22)14 DaysSubject will be asked to respond to the SNOT-22 every day during enrolment to the end-of-study visit. The SNOT-22 is a validated 22-item CRS-specific QoL instrument which is scored where 0=No problem, 1=Very mild problem, 2=Mild or slight problem, 3=Moderate problem, 4=Severe problem, and 5=Problem as bad as it can be
Total Nasal Symptom Score (TNSS) Questionnaire14 DaysSubject will be asked to respond to the TNSS questionnaire every day during enrolment to the end-of-study visit. Total nasal symptoms score (TNSS) is a brief questionnaire which evaluate the severity of main symptoms of allergic rhinitis. It consists of three questions which assess nasal obstruction, itching/sneezing and secretion/runny nose.
