Study to Compare Lefamulin to Moxifloxacin for the Treatment of Adults With Pneumonia

Inclusion Criteria

Each subject must:

• Be male or female at least 18 years of age.
• Provide written informed consent and be willing and able to adhere to the study-specified procedures and restrictions.
• Have an acute illness (less than or equal to 7 days duration) with at least 3 of the following symptoms consistent with a lower respiratory tract infection (new or worsening):
• Dyspnea.
• New or increased cough.
• Purulent sputum production.
• Chest pain due to pneumonia.
• Have at least 2 of the following vital sign abnormalities:
• Fever (body temperature > 38.0 °C (100.4 °F) measured orally or equivalent temperature from an alternate body site) or hypothermia (body temperature 100 beats/min).
• Tachypnea (respiratory rate > 20 breaths/min).
• Have at least 1 other clinical sign or laboratory finding of CABP:
• Hypoxemia (i.e., O2 saturation 10 000 cells/mm3 or 15 % immature neutrophils (bands) regardless of total WBC count.
• Have radiographically-documented pneumonia within 48 hours before enrollment (i.e., infiltrates in a lobar or multilobar distribution or diffuse opacities on chest x-ray or chest computed tomography scan consistent with acute bacterial pneumonia).
• Have a Pneumonia Outcomes Research Team (PORT) Risk Class of II, III, or IV and be an appropriate candidate for oral antibiotic therapy as treatment for the current episode of CABP.

Exclusion Criteria

Each subject must NOT:

• Have received more than a single dose of a short-acting oral or IV antibacterial for CABP within 72 hours before randomization.
• Require concomitant systemic antibacterial therapy potentially effective against CABP pathogens.
• Have been hospitalized for 2 or more days within 90 days prior to the onset of symptoms or have resided in a nursing home or long-term healthcare facility within 30 days prior to the onset of symptoms. NOTE: Residence in an independent living facility is permitted.
• Have confirmed or suspected CABP caused by a pathogen known to be resistant to any of the study drugs (e.g., MRSA, Pseudomonas aeruginosa, any pathogen of the Enterobacteriaceae Family) or attributable to etiologies other than community acquired bacterial pathogens (e.g., ventilator associated pneumonia, hospital acquired bacterial pneumonia, bacterial aspiration pneumonia, Pneumocystis jiroveci pneumonia or other fungal pneumonia, viral or mycobacterial infection of the lung).
• Have a noninfectious cause of pulmonary infiltrates (e.g., pulmonary embolism, chemical pneumonitis from aspiration, hypersensitivity pneumonia, congestive heart failure, bronchial obstruction, lung cancer, cystic fibrosis).
• Have confirmed or suspected pleural empyema (does not include sterile parapneumonic effusions).
