Is this trial a fit for you?

Likely a good fit

Adults (≥18) hospitalized at participating centers with confirmed cIAI or HAP/VAP due to MBL-producing CRE who received on‑label aztreonam‑avibactam for at least 24 hours are ideal candidates.

Probably not a fit

Patients with infections caused by organisms not expected to respond to aztreonam‑avibactam, those under 18, or those enrolled in interventional trials are unlikely to benefit from this study's findings.

What this trial studies

This observational project will collect real‑world treatment and outcome data from Chinese hospitals on adults with confirmed cIAI or HAP/VAP caused by MBL-producing carbapenem‑resistant Enterobacterales who received aztreonam‑avibactam for at least 24 hours. Investigators will record patient characteristics, infection details, microbiology, antibiotic use, hospital length of stay, and clinical outcomes. No experimental interventions are assigned; the study documents care given in routine practice. The aim is to describe how the drug is being used and how patients fare in typical hospital settings in China.

Why it matters

Potential benefit: If successful, the results could help doctors use aztreonam‑avibactam more effectively, potentially improving recovery and shortening hospital stays for patients with these resistant infections.

How similar studies have gone: Clinical development data and recent approvals in Europe, the U.S., and China indicate activity for aztreonam‑avibactam against MBL-producing organisms, but real‑world outcome data—especially from China—are limited.
