Overview
Brief Summary
The purpose of this study is to determine the efficacy, safety, tolerability, and pharmacokinetics (PK) of meropenem-vaborbactam compared to piperacillin/tazobactam for 7 to 14 days in the treatment of hospitalized adults who meet clinical, radiographic, and microbiological criteria for hospital-acquired bacterial pneumonia (HABP) or ventilator-associated bacterial pneumonia (VABP).
Investigators
Eligibility Criteria
Inclusion Criteria
- •Willingness to comply with all study procedures and provide a signed written informed consent prior to any study-specific procedures; however, if unable to do so, the participant's legally authorized representative may provide written consent as approved by institutional-specific guidelines. Participants who are unconscious or considered by the investigator to be clinically unable to consent at Screening and who are entered into the study by the consent of a legally authorized representative, should provide their own written informed consent for continuing to participate in the study as soon as possible on recovery, as applicable in accordance with local regulations.
- •Hospitalized male or female participants, ≥18 years of age.
- •Females must be surgically sterile or at least 2 years postmenopausal, or if of childbearing potential, have a negative screening urine pregnancy test and be willing to practice sexual abstinence or use an accepted form of contraception with her partner (for example, barrier or hormonal methods) during treatment and for at least 28 days after the last dose of study drug.
- •Expectation, in the opinion of the Investigator, that the participant's infection will require treatment with IV antibiotics for a minimum of 7 days.
- •Have a confirmed diagnosis of HABP or VABP requiring antibiotic therapy by meeting all clinical, microbiological, and radiographic criteria as defined in the following:
- •For HABP participants:
- •To meet the study definition of HABP, participants must meet all of the following clinical, microbiological, and radiographic criteria:
- •A chest radiograph (chest X-ray \[CXR\], magnetic resonance imaging \[MRI\] or computed tomography \[CT\]) reveals the presence of new or progressive pulmonary infiltrate(s) consistent with bacterial pneumonia within 48 hours prior to randomization.
- •Onset of symptoms at least 48 hours after hospitalization or within 7 days after discharge from an inpatient acute or chronic care facility (for example, long-term care, rehabilitation center, hospital, or skilled nursing home).
- •Have at least one of the following:
Exclusion Criteria
- •Participants who meet any of the following exclusion criteria will not be enrolled in the study:
- •History of any severe hypersensitivity to any beta-lactam antibiotic (for example, cephalosporins, penicillins, or carbapenems).
- •History of any severe allergic reaction that would preclude the use of either all aminoglycosides or adjunctive gram-positive antimicrobials (that is, allergy to both glycopeptides and oxazolidinones).
- •Requirement or anticipated need for additional systemic antibiotic (other than study drug) or antifungal, including prophylactic antimicrobials and antifungals.
- •Requirement or anticipated need for more than 14 days of systemic antimicrobial therapy to treat HABP or VABP.
- •Known deep-tissue infection (including undrained abscess, meningitis, endocarditis, or osteomyelitis) within 7 days prior to randomization.
- •Participant has received more than 24 hours of any potentially effective systemic antibacterial therapy for the current episode of HABP or VABP within 72 hours before randomization. Exceptions:
- •Evidence of clinical failure of the current episode of HABP or VABP (for example, worsening signs and symptoms) following at least 48 hours of prior systemic antimicrobial therapy (participants with evidence of clinical failure of piperacillin/tazobactam are not eligible for inclusion), or
- •The clinical symptoms and signs of the current episode of HABP or VABP started at least 48 hours after the prior antibacterial therapy was initiated.
- •Pulmonary disease that precludes evaluation of a therapeutic response (including, but not limited to, lung cancer, active tuberculosis, cystic fibrosis, granulomatous disease, fungal pulmonary infection, pulmonary embolism, lung abscess, pleural empyema, or post obstructive pneumonia).
Arms & Interventions

Meropenem-Vaborbactam VABP
Participants with a clinical diagnosis of VABP will be treated with meropenem 2 g and vaborbactam 2 g in 250 mL infused intravenously for 3 hours every 8 hours for 7 days to a maximum of 14 days.
Intervention: Meropenem-Vaborbactam
Piperacillin/Tazobactam VABP
Participants with a clinical diagnosis of VABP will be treated with piperacillin 4 g and tazobactam 0.5 g in 100 mL infused intravenously for 30 minutes every 6 hours for 7 days to a maximum of 14 days.
