What this trial studies

This clinical trial evaluates the effectiveness of a new antibiotic regimen consisting of ceftriaxone, clarithromycin, and metronidazole compared to the standard treatment of ampicillin/amoxicillin and azithromycin or erythromycin for pregnant individuals with preterm premature rupture of membranes (PPROM). The study aims to prolong pregnancy and reduce adverse perinatal outcomes by administering these antibiotics during hospitalization for expectant management. Participants will be randomly assigned to receive either treatment for a duration of seven days, and outcomes will be monitored to assess the efficacy of the new regimen. The trial is designed as an unblinded pragmatic randomized controlled trial to reflect real-world clinical practice.

Who should consider this trial

Good fit: Ideal candidates for this study are pregnant individuals aged 18 and older, between 23 and 32 weeks of gestation, who are admitted for expectant management of PPROM.

Not a fit: Patients who have received more than one dose of prophylactic antibiotics or have a suspected or confirmed infection requiring treatment may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved pregnancy outcomes and reduced complications for patients with PPROM.

How similar studies have performed: Previous observational studies have shown success with similar antibiotic regimens, indicating potential for this approach.
