NCT ID NCT05204563
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested a new antibiotic combination (IMI-XNW4107) against an existing one (IMI/REL) in 450 adults with serious pneumonia caught in the hospital or from a ventilator. The main goal was to see if the new drug was at least as good at preventing death within 14 days. Both treatments are given through an IV and aim to control the infection.
