Extended azithromycin treatment in prelabor rupture of membranes at periviable gestations

Official title: Extended Azithromycin Treatment in Peri-viable and Extremely Preterm Prelabor Rupture of Membranes: A Pilot Study

Run by University of Pittsburgh · NCT07669207 · Data updated 2026-11-12

This study tests whether giving extra doses of azithromycin beyond the standard antibiotics can improve outcomes for pregnant people with PPROM between 22 and 28 weeks.

Is this trial a fit for you?

Likely a good fit

Pregnant people with singleton gestations between 22 0/7 and 28 0/7 weeks who are choosing expectant management after MFM/neonatology consultation and remain pregnant 48 hours after presentation.

Probably not a fit

Patients who do not respond to antibiotics or who have contraindications to azithromycin or expectant management may not benefit.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This pilot, non-blinded randomized trial compares standard antibiotic therapy for PPROM with the same therapy plus seven additional doses of oral azithromycin 500 mg every other day. The goal is to see if extended azithromycin is feasible to study, and to gather preliminary data on pregnancy latency and maternal and neonatal outcomes. Participants will complete surveys about their experience and any side effects. The study will inform the design of a larger, future trial.

Why it matters

Potential benefit: If successful, extended azithromycin could potentially prolong pregnancy and reduce maternal or neonatal complications.

How similar studies have gone: Previous antibiotic treatment for PPROM improves latency and outcomes, but optimal azithromycin dosing remains uncertain; this feasibility study explores a novel extended dosing approach.
