Imipenem/Cilastatin-XNW4107 Versus Imipenem/Cilastatin/Relebactam for Treatment of Participants With Bacterial Pneumonia (XNW4107-302, REITAB-2)

Completed · Phase 3

Conditions studied: Hospital Acquired Bacterial Pneumonia or Ventilator-Associated Bacterial Pneumonia

In brief

This study aims to compare treatment with Imipenem/Cilastatin-XNW4107 (IMI-XNW4107) with imipenem/cilastatin/relebactam (IMI/REL) in participants with hospital-acquired or ventilator-associated bacterial pneumonia (HABP or VAPB, respectively). The primary hypothesis is that IMI-XNW4107 is non-inferior to IMI/REL in all-cause mortality.
