Subjects willing and able to provide written informed consent or where consent is provided by legally authorized representatives., Female subjects of childbearing potential, who are willing to use a highly effective method of birth control during the study and for at least 30 days following the last dose of study medication. a. Childbearing potential is defined as any female who has experienced menarche and does not meet the criteria for postmenopausal, which is defined as the past 12 months with no menses without an alternative medical cause or permanently sterilized (e.g., has undergone bilateral tubal occlusion/ligation, hysterectomy, bilateral oophorectomy, bilateral salpingectomy) / b. A highly effective method of birth control is defined as one that results in a low failure rate (i.e., <1% per year) when used consistently and correctly, such as implants, injectables, combined oral contraceptives, intrauterine devices, sexual abstinence, or a vasectomized partner., Male subjects with female sexual partners of childbearing potential are eligible for inclusion if they agree to use medically acceptable birth control for 90 days following the last dose of study medication. Sexual abstinence, vasectomy, or a condom used with a spermicide are medically acceptable birth control methods for males. Male subjects must agree not to donate sperm for a period of 90 days after the last dose of study treatment., Willing and able to comply with all study assessments and adhere to the protocol schedule., Male or female subjects =18 years on the day of signing informed consent., Has HABP or VABP as defined below and requires treatment with IV antibiotic therapy. NOTE: HABP is defined as the onset of acute bacterial pneumonia symptoms at least 48 hours after hospitalization or within 7 days after discharge from an inpatient acute or chronic care facility (e.g., long-term care, rehabilitation center, hospital, or skilled nursing home). Subjects may experience acute respiratory failure and require mechanical ventilation for HABP (vHABP). VABP is defined as acute bacterial pneumonia in a subject receiving mechanical ventilation via an endotracheal (or nasotracheal) tube or tracheostomy for =48 hours., All subjects must fulfill at least 1 of the following clinical criteria at screening: a. New onset or worsening of pulmonary symptoms or signs, such as cough, dyspnea, tachypnea (e.g., respiratory rate >25 breaths/minute), expectorated sputum production, or requirement for mechanical ventilation / b. Hypoxemia (e.g., partial pressure of oxygen [PaO2] <60 mmHg while the subject is breathing room air, as determined by arterial blood gas [ABG], or worsening of the ratio of the PaO2 to the fraction of inspired oxygen [PaO2/FiO2]) / c. Need for acute changes in the ventilator support system to enhance oxygenation, as determined by worsening oxygenation (ABG or PaO2/FiO2) or needed changes in the amount of positive end-expiratory pressure / d. New onset of or increase in (characteristics or quantity) suctioned respiratory secretions, demonstrating evidence of inflammation and absence of contamination., All subjects must have at least 1 of the following signs and symptoms/laboratory abnormalities at screening: a. Documented fever (i.e., core body temperature [tympanic, rectal, esophageal] =38°C [100.4°F], oral temperature =37.5°C [99.5°F], or axillary temperature =37°C [98.6°F]) / b. Hypothermia (i.e., core body temperature [tympanic, rectal, esophageal] =35°C [9
If a Gram stain from a respiratory sample is available and shows only Gram-positive cocci., Renal function at screening as estimated glomerular filtration rate (eGFR) <15 mL/min or >250 mL/min, calculated as individual eGFR derived from Modification of Diet in Renal Disease formula., Subject is receiving hemodialysis or peritoneal dialysis or micro-dialysis or continuous venovenous hemofiltration or continuous venovenous hemodialysis., Subject is anticipated to be treated with any of the following medications during the course of study therapy: a. Valproic acid or divalproex sodium (or has used valproic acid or divalproex sodium in the 2 weeks prior to screening) NOTE: Subjects who are receiving valproic acid or divalproex sodium for seizure prophylaxis (e.g. for head trauma) without history of seizure disorder may be enrolled as judged by the investigator / b. Concomitant systemic (IV or oral) Gram-negative antibacterial agents in addition to those designated in the study treatment groups / c. Concomitant systemic (IV or oral) antifungal or antiviral therapy for the index infection of HABP/VABP., Life expectancy is <3 days., Subjects in refractory septic shock, defined as persistent hypotension despite adequate fluid resuscitation and vasopressive therapy at the time of randomization., Subjects with 1 or more of the following laboratory abnormalities in baseline specimens: aspartate aminotransferase, alanine aminotransferase >3 × the upper limit of normal (ULN), total bilirubin level >2 × ULN (except for isolated hyperbilirubinemia due to known Gilbert’s disease), neutrophils <500 cells/mm^3, platelet count <40,000/mm^3., History of active liver disease or cirrhosis., Subjects with an APACHE II score of >30., A female who is pregnant or breastfeeding or has a positive pregnancy test at screening., Subject is participating in any clinical study of any investigational medication (i.e., non-licensed medication) during the 30 days prior to randomization. COVID-19 vaccines that are given under emergency use authorization are not considered investigational agents., Subjects who have known or suspected community-acquired bacterial pneumonia, atypical pneumonia, viral pneumonia including Coronavirus disease (COVID-19), or chemical pneumonia (including aspiration of gastric contents, inhalation injury)., Any other condition or prior therapy, which, in the opinion of the investigator, would make the subject unsuitable for this study., Subjects who have HABP/VABP caused by an obstructive process, including lung cancer (or other malignancy metastatic to the lungs resulting in pulmonary obstruction) or other known obstruction., Have received effective systemic and inhaled Gram-negative antibacterial drug therapy for the index infection of HABP/VABP for a continuous duration of more than 24 hours during the previous 72 hours prior to randomization. NOTE: Subjects who have objective documentation of clinical failure (i.e., have persistent/worsening signs and/or symptoms of HABP/VABP at screening) while receiving any duration of prior antibacterial drug therapy for the treatment of HABP/VABP can be enrolled., Has a concurrent condition or infection that, in the investigator's judgment, would preclude evaluation of therapeutic response (e.g., active tuberculosis, cystic fibrosis, granulomatous disease, a disseminated fungal infection, invasive fungal pulmonary infection, or endocarditis)., Subjects who have central nervous system infection (e.g., menin
