Is this trial a fit for you?

Likely a good fit

Pregnant people aged 18–50 with a singleton pregnancy and PPROM between 34.0 and 36.6 weeks who are not in active labor and have no macrolide allergy are ideal candidates.

Probably not a fit

Those in active labor, with multiple gestation, suspected chorioamnionitis, fetal compromise, major fetal anomalies, or macrolide sensitivity would not be expected to benefit from this comparison.

What this trial studies

This phase 4 interventional trial enrolls pregnant people with singleton preterm premature rupture of membranes (PPROM) between 34.0 and 36.6 weeks to compare two antibiotic regimens. Participants are randomized to receive standard intravenous ampicillin followed by oral amoxicillin alone or the same regimen plus a single oral dose of azithromycin, and they remain hospitalized until delivery. Investigators monitor maternal signs of infection, time from membrane rupture to delivery (latency), and neonatal outcomes including serious morbidity and need for NICU support. The trial aims to determine whether broader antibiotic coverage in the late preterm period reduces neonatal complications or prolongs latency compared with current standard care.

Why it matters

Potential benefit: If successful, adding azithromycin could reduce serious neonatal infections and respiratory complications and lower NICU admissions by preventing ascending infection or prolonging pregnancy.

How similar studies have gone: Large randomized trials in earlier preterm PPROM (<32 weeks) showed benefit from combining ampicillin with a macrolide like erythromycin or azithromycin, but randomized evidence specifically in the late preterm window (34.0–36.6 weeks) is limited.
