Glenmark nasal spray cuts down COVID viral load by 94 percent in 24 hours: Study

The study demonstrated that patients who received NONS had significant reduction in viral load within 24 hours, which was sustained over seven days of treatment. Viral load was reduced by 93.7% within 24 hours and by 99% within 48 hours of treatment with NONS. The average change from baseline in log viral RNA load through the entire treatment duration was statistically superior with NONS compared to placebo. Similar results were observed in vaccinated and unvaccinated populations. The study was conducted during the delta and omicron surges. Key secondary endpoints including clinical improvement assessed by WHO Clinical Progression Scale Score and extent/rapidity of virologic recovery was demonstrated in patients using NONS. The median time to virological cure was three days in the NONS group and seven days in the placebo group after start of treatment (four days sooner). The exploratory evaluation of the proportion of immediate contacts having a positive COVID-19 test or becoming symptomatic, remained nearly the same in the NONS group while it numerically increased in the placebo group over the treatment.
