Meropenem plus pralurbactam versus ceftazidime–avibactam for hospital- and ventilator-associated bacterial pneumonia

Official title: A Multicenter, Randomized, Double-blind, Active-Controlled, Parallel, Phase Ⅲ Study to Evaluate the Efficacy and Safety of Meropenem and Pralurbactam for Injection Compared to Ceftazidime and Avibactam Sodium for Injection in Subjects With Hospital-acquired and Ventilator-associated Bacterial Pneumonia

Run by Qilu Pharmaceutical Co., Ltd. · NCT07327619 · Data updated 2026-11-12

This trial will test whether meropenem combined with pralurbactam works as well and is as safe as ceftazidime–avibactam in adults with hospital-acquired or ventilator-associated bacterial pneumonia.

Is this trial a fit for you?

Likely a good fit

Adults aged 18–80 with a confirmed diagnosis of hospital-acquired or ventilator-associated bacterial pneumonia, new or worsening infiltrates on chest imaging, systemic and respiratory signs, and an expected survival of at least 28 days are the intended participants.

Probably not a fit

Patients with community-acquired, atypical, viral, or chemical pneumonia, with APACHE II scores over 30, with prolonged recent antibiotic exposure, or with known severe allergy to carbapenems/cephalosporins/other beta-lactams are unlikely to benefit from joining this trial.

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

What this trial studies

This is a Phase 3, randomized, double-blind, active-controlled non-inferiority trial comparing meropenem plus pralurbactam to ceftazidime–avibactam in adults with hospital-acquired or ventilator-associated bacterial pneumonia. Adult participants with new or worsening pulmonary infiltrates and systemic and respiratory signs are randomized to one of the two antibiotic regimens and followed for about 32 days including screening and follow-up. The primary focus is clinical efficacy (non-inferiority) and safety of the meropenem–pralurbactam combination versus the active comparator. Concomitant eligibility and exclusion criteria limit enrollment to patients without viral/atypical/chemical pneumonias, without very high illness severity (APACHE II >30), and without certain recent prolonged antibiotic exposures or beta-lactam allergies.

Why it matters

Potential benefit: If successful, this regimen could offer an effective alternative antibiotic option for adults with serious hospital- or ventilator-associated pneumonia, potentially improving treatment choices against resistant Gram-negative bacteria.

How similar studies have gone: Previous studies of ceftazidime–avibactam and various beta-lactam/beta-lactamase inhibitor combinations have shown activity in serious Gram-negative pneumonia, but direct Phase 3 comparisons including meropenem–pralurbactam are limited, so the approach is partially supported but not yet fully established.
