NCT07041671
Evaluation Viral RNA and Virus Infectivity in Exhaled Air Before and After Use of One Dose With ColdZyme Mouth Spray
Many respiratory diseases spread through aerosols. ColdZyme is a mouth spray that protects against upper respiratory tract viruses causing common cold and flu-like symptoms. ColdZyme forms a protective moisturizing barrier on the mucous membrane of the oral cavity and throat. The objective of this study is assessing if ColdZyme could also contribute to decreased airborne transmission by decreasing the amount of (infectious) virus that is exhaled by an infected subject.

A Study to Assess the Effect Probiotic Supplement on Immune Health in Teachers Prone to Upper Respiratory Tract Infection
The present study is a randomized, placebo-controlled, double-blind, parallel-group clinical studydesigned to assess the effects of IP on immune health in teachers prone to URTI. Approximately 179individuals aged between 18 and 50 years will be screened. Considering a screen failure of 20%,approximately 144 individuals will be randomized in a ratio of 1:1 to receive either the active orplacebo. The study will have at least 100 completed participants i.e. 50 participants in each studyarm after accounting for a dropout/withdrawal rate of 30% at the end of the study. The interventionand follow-up duration for all the study participants will be 120 days.
