E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To determine noninferiority (NI) in early clinical response rate (defined as improvement at 72 [±12] hours after the first dose of study drug), in at least 2 of the following 4 cardinal symptoms: cough, shortness of breath, chest pain, and sputum production, (without worsening of any) of oral solithromycin compared to oral moxifloxacin in adult patients with community-acquired bacterial
pneumonia (CABP) in the Intent to Treat (ITT) population. |
|
E.2.2 | Secondary objectives of the trial |
• To determine NI in early clinical response rate at 72 (±12) hours after the first dose of study drug of oral solithromycin compared to oral moxifloxacin in the weighted pooled microbiological ITT (mITT) population (randomized patients with an identified pathogen associated with CABP). For this analysis, data from protocol CE01-300 will be pooled with data from a second NI study of solithromycin in CABP.
• To determine NI in early clinical response rate of oral solithromycin compared to oral moxifloxacin in the mITT population.
• To determine the overall clinical success rates of oral solithromycin compared to moxifloxacin at the Short-term Follow-Up Visit (SFU), 5-10 days after the last dose of study drug in the ITT and clinically evaluable (CE-SFU) populations.
• To assess the safety and tolerability of oral solithromycin compared to oral moxifloxacin in adult patients with CABP.
• To assess oral solithromycin pharmacokinetics (PK) in adult patients with CABP. |

b. Production of purulent sputum
c. Shortness of breath (dyspnea)
d. Chest pain due to pneumonia
3. At least 1 of the following:
a. Fever: [defined as body temperature >38°C (100.4°F) measured orally, >38.5°C (101.3°F) measured tympanically, or >39°C (102.2°F) measured rectally]
b. Hypothermia: [defined as body temperature <35°C (95.0°F) measured orally, <35.5°C (95.9°F) measured tympanically, or <36°C (96.8°F) measured rectally]
c. Presence of pulmonary rales and/or evidence of pulmonary consolidation (dullness on percussion, bronchial breath sounds, or egophony)
4. The patient will have received no systemic antibiotics other than a single dose of a short-acting antibiotic (penicillins, cephalosporins [not ceftriaxone], tetracyclines, or trimethoprimsulfamethoxazole) in the 7 days prior to enrollment.

intrauterine device, sexual abstinence, or a vasectomized partner) while participating in the study and for 30 days after the last dose of study drug.
10. Males must agree to use a double barrier method of contraception (condom plus spermicide or diaphragm plus spermicide) while participating in the study and for 30 days after the last dose of study drug, or the male patient or his female partner must be surgically sterile (e.g. vasectomy, tubal ligation) or the female partner must be post-menopausal.
11. The patient must provide written informed consent.
12. The patient must be willing and able to attend all study visits and comply with all study procedures. |

5. Hospitalization within 90 days or residence in a long-term care facility within 30 days prior to the onset of symptoms (i.e. healthcare-associated pneumonia).
6. Any condition that could affect drug absorption, e.g. status post gastrectomy.
7. History of post-antibiotic colitis within the last 3 months.
8. Mean QTcF (QT interval corrected with the Fridericia formula) greater than 450 msec on screening summary (or triplicate) electrocardiogram (ECG).
