Antibiotics for early water break study halted before start
NCT ID NCT06917157
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study aimed to see if giving antibiotics to pregnant people whose water broke very early (before 22 weeks) could delay delivery and improve baby health. It was planned for those with a single baby and recent membrane rupture. However, the study was withdrawn before enrolling anyone, so no results are available.
