Evaluating the Plasma, Epithelial Lining, and Alveolar Macrophage Concentrations of Intravenous Carbavance™ (RPX2014/RPX7009) in Healthy Adult Subjects

1. Healthy adult males and/or females, 18 to 55 years of age (inclusive) at the time of screening.
2. Body mass index (BMI) ≥ 18.5 and ≤ 30 (kg/m2) and weight between 55.0 and 100.0 kg (inclusive) at the time of screening.
3. Medically healthy with clinically insignificant screening results (e.g., laboratory profiles, medical histories, electrocardiograms (ECGs), physical examination) as deemed by the PI.
4. Non-tobacco/nicotine-containing product users for a minimum of 6 months prior to Day 1.
5. Voluntarily consent to participate in the study.

7. History of seizures (e.g., epilepsy), head injury or meningitis requiring ongoing anti-seizure medications.
8. Use of any prescription medication (with the exception of hormonal contraceptives or hormone replacement therapy for females) within 14 days prior to Day 1.

12. Any acute illness including clinically significant infection within 30 days prior to Day 1.
13. QTcF interval >450 msec, or history of prolonged QT syndrome at screening (or Day 1).
14. Calculated creatinine clearance less than 80 mL/min (Cockroft-Gault method) at screening.

15. Subjects who have any clinically significant abnormalities on laboratory values at screening (or Day -1), including:

    1. White blood cell count (WBC) \< 3,000/mm3, hemoglobin \< 11g/dL.
    2. Absolute neutrophil count \< 1,200/mm3 or platelet count \< 120,000/mm3.
16. Liver function abnormalities at screening (or Day -1) (defined by an elevation in bilirubin, AST or ALT 1.5 x ULN of the normal range for subjects based on age and sex).
