The Covixyl-V LAEH Nasal Spray's safety and efficay is clinically tested for use in subjects with COVID-19 infection.

A randomized, double-blind, multi-center study is conducted to evaluate the efficacy and safety of ethyl lauroyl arginate hydrochloride (LAEH) formulation versus a matching placebo formulation administered as a nasal spray to reduce viral load from nasal area of subjects with coronavirus disease 2019 (COVID-19).

The primary endpoint for this study was the comparison of change in viral load in RT-PCR Test.

Proportion of COVID-19 infection-free subjects between the two treatment arms was followed.

7. Had received antibiotic/s, antiviral drug, and hormonal drugs within 30 days prior to the day of enrollment
8. Any condition or disease detected during the medical interview/physical examination that would render the subject unsuitable for the study, place the subject at undue risk or interfere with the ability of the subject to complete the study in the opinion of the Investigator
9. Had received or had a plan to receive a SARS-CoV-2 vaccine during the study period
10. Participated in any interventional drug or medical device trials within 30 days prior to the day of enrollment.

In the study, 33 subjects were screened and 3 of them failed in screening tests. Total 30 subjects were enrolled in the study. Out of these 30 enrolled subjects, 15 subjects were randomized to Covixyl-V group and 15 subjects were randomized to placebo group
