NCT ID NCT07578012
First seen Jun 27, 2026 · Last updated Jul 09, 2026 · Updated 2 times
Summary
This study tests whether PMBL® sublingual tablets can reduce the number of respiratory infections (like colds) in children aged 3 to 12 who are prone to getting sick. Half the children will receive the active tablet, and half will receive a placebo (inactive tablet) for 3 months, with 4 more months of follow-up. The goal is to see if the treatment lowers infection rates and antibiotic use.
