Negative PCR results appeared earlier and more frequently in the azelastine treated groups: being 18.52% and 21.43% in the 0.1% and 0.02% groups, respectively, compared to 0% for placebo on day 8. Duration of culturable SARS-CoV-2 in hospitalized patients with covid-19. Thus, antibody therapy (bamlanivimab and etesevimab) in positively tested, non-hospitalized patients demonstrated that treatment resulted in decreased SARS-CoV-2 viral load by log100.57 on day 11, which was significantly greater compared to placebo (p=0.01)33.
