New antibiotic cocktail aims to delay preterm birth after water breaks
NCT ID NCT06396078
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether a 7-day course of three antibiotics (ceftriaxone, clarithromycin, metronidazole) can prolong pregnancy better than the current standard antibiotics in pregnant people hospitalized after their water breaks early (before 34 weeks). About 56 participants will be randomly assigned to one of the two antibiotic regimens. The goal is to see if the new combination delays delivery and reduces serious health problems for the newborn.
