A Phase 3b Randomized, Double-blind, Multi-center Study to Compare the Safety and Efficacy of Omadacycline IV/PO to Moxifloxacin IV/PO for Treating Adult Subjects With Community-acquired Bacterial Pneumonia (CABP)

ZL-2401-004

The primary objective of the study is to show that in Chinese adults with CABP, a course of IV/PO treatment with omadacycline has similar clinical efficacy as the with the comparator antibiotic, IV/PO moxifloxacin. The study is designed as a bridging study, to confirm the results of the pivotal global CABP trial in an ethnically different population of Chinese.

Has at least 3 of the following symptoms: * Cough * Production of purulent sputum * Dyspnea (shortness of breath) * Chest pain 4. Has at least 2 of the following abnormal vital signs: * Fever or hypothermia documented by the investigator (temperature \> 38.0°C or \< 36.0°C) * Hypotension with systolic blood pressure (SBP) \< 90 mmHg * Heart rate (HR) \> 90 beats per minute (bpm) * Respiratory rate (RR) \> 20 breaths/minute Exclusion Criteria: 1. Has received antibacterial treatment \>24hr within the 72hr window prior to randomization. Subjects may be eligible despite prior antibacterial therapy if they had been treated with short action time antimicrobial for ≤24h, or if they have received \> 48 hours of prior systemic antibacterial therapy for the current episode of CABP with unequivocal clinical evidence of treatment failure. 2. Is known or suspected to have CABP caused by a pathogen that may be resistant to either test article (eg, Klebsiella pneumoniae, Pseudomonas aeruginosa, Pneumocystis jiroveci, obligate anaerobes, mycobacteria, fungal pathogens). 3.
