入选标准

•1. Subject must be = 18 years of age.
•2. Evidence of a personally signed and dated informed consent document indicating that the subject or a legally acceptable representative has been informed of all pertinent aspects of the study. If a subject is unable to consent for themselves at Screening, the subject’s legally acceptable representative may provide written consent, in accordance with the country-specific regulations. Those subjects who are unconscious or considered by the investigator clinically unable to consent at Screening and who are entered into the study by the consent of a legally acceptable 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 .
•3. Subjects must have a confirmed diagnosis of serious bacterial infection, specifically cIAI, HAP/VAP, cUTI, or BSI requiring administration of IV antibacterial therapy (see additional Inclusion Criteria on HAP/VAP, cIAI, cUTI, or BSI for minimum disease criteria).
•4. Subjects must have an MBL- positive Gram-negative bacteria (an Enterobacteriaceae and/or Stenotrophomonas maltophilia for which the imipenem or meropenem MIC is = 4 µg/mL), that was isolated from an appropriate specimen obtained within 5 days prior to screening (the study qualifying pathogen, which was determined to be the causative agent of entry infection and which is available to be sent to the central laboratory). Prior to screening, genotypic confirmation of an MBL-positive pathogen at the local laboratory is required. If this is not possible then selected phenotypic tests may be acceptable with prior approval of the sponsor. In the case of
•mixed infection, the subject is allowed to participate in the study if the species are deemed susceptible to ATM-AVI or the investigator considers that the additional species are colonizers which do not warrant specific treatment.
•5. Female subjects of nonchildbearing potential must meet at least 1 of the following criteria:
•a. Achieved postmenopausal status, defined as follows: cessation of regular menses for at least 12 consecutive months with no alternative pathological or
•physiological cause; and status may be confirmed with a serum follicle-stimulating hormone (FSH) level confirming the postmenopausal state;
•b. Have undergone a documented hysterectomy and/or bilateral oophorectomy;
•c. Have medically confirmed ovarian failure.
•Note: All other female subjects (including female subjects with tubal ligations) are considered to be of childbearing potential.
•6. Female subject of childbearing potential must have a negative serum or urine pregnancy test, with sensitivity of at least 25 mIU/mL.
•7. Subjects who have received appropriate prior systemic antibiotic[s] for a
•carbapenem-non-susceptible pathogen must meet the following criteria (Note: antibiotic[s] is considered appropriate if microbiological susceptibility test results show that all carbapenem- non-susceptible pathogens are susceptible to the systemic antibiotic[s] received):
•a. Worsening or lack of improvement of objective symptoms or signs of infection after at least 48 hours of antibacterial therapy.
•8. Subject must be willing and able to comply with scheduled visits, treatment plan, laboratory tests, and other study procedures.
•Are the trial subjects under 18? no
•Number of subjects for this age range:
•F.1.2 Adults (18-64 years) yes
•F.1.2.1 Number of subjects for t

排除标准

•1. Subject has an Acute Physiology and Chronic Health Evaluation (APACHE) II score >30.
•2. Clinical judgment by the investigator that the subject has a high likelihood of dying within the specified study treatment period despite delivery of adequate antibiotics for treatment of the index infection.
•3. Subject has a history of serious allergy such as anaphylaxis, angioedema and
•bronchospasm, hypersensitivity or any serious reactions to any systemic antibacterial which is allowed per protocol including ATM, carbapenem, monobactam or other ß-lactam antibiotics, AVI, colistimethate or polymyxin B, nitroimidazoles or MTZ, vancomycin, linezolid, daptomycin, aminoglycosides (eg, amikacin, gentamicin, tobramycin), or any of the excipients of the respective (investigational) medicinal products to be administered during the study.
•4. Subject is unlikely to respond to up to 14 days of study treatment.
•5. Subject has a concurrent infection that may interfere with the evaluation of response to the study antibiotics.
•6. Subject has a need for effective concomitant systemic antibacterials in addition to those allowed per protocol for the diagnoses under study.
•7. Subject has known Clostridium difficile associated diarrhoea.
•8. Subjects receiving hemodialysis or peritoneal dialysis.
•9. Subject has an estimated CrCL = 15 mL/min by Cockcroft-Gault formula (Cockcroft and Gault 1976), receiving or requirement for peritoneal dialysis, haemodialysis or hemofiltration.
•10. Presence of hepatic disease as indicated by alanine transaminase (ALT) or aspartate aminotransferase (AST) >3 × upper limit of normal (ULN) at Screening. However, subjects with AST and/or ALT up to 5 × ULN are eligible if these elevations are acute and are documented as being directly related to the infectious process being treated.
•11. Subject has a total bilirubin >2 × ULN, unless isolated hyperbilirubinemia is directly related to the acute infection or due to known Gilbert's disease.
•12. Subject has acute hepatitis or acute hepatic failure, cirrhosis or chronic hepatic failure (any Child-Pugh class).
•13. Alkaline phosphatase >3.0 × ULN. However, subjects with values >3.0 × ULN and <5.0 x ULN are eligible if this value is acute and directly related to the infectious process being treated. This must be documented.
•14. Subject has an absolute neutrophil count <500/mm3.
•15. Subject has a perinephric infection.
•16. Subject has previously been treated with ATM-AVI.
•17. Subject has been previously enrolled in this study.
•18. Pregnant female subjects; breastfeeding female subjects; fertile male subjects and female subjects of childbearing potential who are unwilling or unable to use a highly effective method of contraception as outlined in this protocol for the duration of the study treatment and for at least 7 days after the last infusion of investigational product.
•19. Subject is participating in or has participated in other studies involving investigational drug(s) within the last 30 days (or five times the half-life of the previously administered investigational compound, whichever is longer) prior to screening and/or during study participation.
•20. Subject has other acute or chronic medical or psychiatric condition including recent (within the past year) or active suicidal ideation or behavior or laboratory abnormality that may increase the risk associated with study participation or investigational product administration or may interfere with the interpretation of stud
