A Phase 3 Prospective, Randomized, Multicenter, Active-controlled Study to Evaluate the Efficacy and Safety of BV100 Plus Low-dose Polymyxin B Compared With Colistin Plus High-dose Ampicillin/Sulbactam in the Treatment of Adult Patients With Hospital-acquired Bacterial Pneumonia and Ventilator-associated Bacterial Pneumonia Caused by Carbapenem-resistant Acinetobacter Baumannii-calcoaceticus Complex
This is a two-part study, with Part A being the randomized, controlled portion of the study in patients with hospital-acquired bacterial pneumonia (HABP) or ventilator-associated bacterial pneumonia (VABP) suspected or confirmed to be due to carbapenem-resistant Acinetobacter baumannii-calcoaceticus complex (CRABC). Part B is the single-group portion of the study and includes patients with HABP or VABP with CRABC infections that are resistant to or have failed colistin/polymyxin B treatment.
• Provide written informed consent prior to any study related procedures not part of normal medical care. If permitted by local country and institution-specific guidelines, surrogate consent/use of a legally authorized representative may be provided. Alternatively, the decision can be made according to the procedure permitted by local law and institutional Standard Operating Procedures. If a patient regains consciousness while in the study and, per the Investigator's judgment, the patient is able to read, assess, understand, and make his/her own decision to participate in the study, the patient may agree to continue participation. In such cases, the patient must be reconsented.
• Male or female patients, ≥ 18 and ≤ 82 years of age at the time of signing informed consent.
• A confirmed diagnosis of HABP or VABP requiring treatment with IV antibiotics in the judgment of the Investigator.
• High probability of a pneumonia (HABP or VABP) due to ABC as a single pathogen, or member of a polymicrobial infection based on evidence from RDT from a sample collected within 48 hours prior to randomization, AND one of the following:
‣ Has received no more than 48 hours of potentially active antimicrobial treatment against CRABC prior to the first dose of study drug; OR
⁃ Is clinically failing prior treatment regimens (i.e., clinical deterioration or failure to improve after at least 48 hours of antibiotic treatment).
• An APACHE II \< 30 or qSOFA score ≥ 2 at Screening.
• Women of childbearing potential must have a negative highly sensitive urine or serum pregnancy test before randomization. Participating women of childbearing potential must be willing to consistently use one highly effective method of contraception from Screening until at least 30 days after administration of the last dose of study drug.
• Diagnosed with HABP or VABP
