NCT04774094

Brief Summary

This is a prospective, single arm, open-label, multi-center clinical study evaluating the effectiveness and safety of CAZ-AVI in participants with HAP (including VAP), who have initiated treatment with CAZ-AVI in an inpatient hospital setting. The duration of antibiotic treatment with the CAZ-AVI is 7-14 days. Participants must receive intravenously (IV) CAZ-AVI in the hospital for at least 7 full days. There are no formal hypothesis tests planned for this study. The number and percent of participants having clinical cure, failure, and indeterminate at TOC visit in the cMITT analysis population will be summarized.

Outcome Measures

Primary Outcomes (1)

  • Percentage of Participants With Clinical Cure at Test of Cure (TOC) Visit: Clinical Modified Intent-to-Treat (cMITT) Population

    Clinical cure: participants were considered to be a success for clinical response at TOC visit if the participants were not a clinical failure at end of treatment (EOT), and the participants were alive and all signs and symptoms of pneumonia were resolved or improved to an extent that no antibacterial therapy for HAP was taken between EOT and TOC inclusive. Gram negative is abbreviated as gram -ve and gram positive as gram +ve.

    TOC visit: any day from Day 21 to 25

Secondary Outcomes (11)

  • Percentage of Participants With Clinical Cure at EOT Visit: cMITT Population

    EOT visit: within 24 hours after the completion of the last infusion of study intervention (study treatment was a minimum of 7 days and maximum of 14 days)

  • Percentage of Participants With Clinical Cure at EOT and TOC Visit: Microbiological Modified Intent-to-Treat (mMITT) Population

    EOT visit: within 24 hours after the completion of the last infusion of study intervention (study treatment was a minimum of 7 days and maximum of 14 days); TOC visit: any day from Day 21 to 25

  • Percentage of Participants With Favorable Per-Participant Microbiological Response at the EOT and TOC Visits: mMITT Population

    EOT visit: within 24 hours after the completion of the last infusion of study intervention (study treatment was a minimum of 7 days and maximum of 14 days); TOC visit: any day from Day 21 to 25

  • Percentage of Participants With Favorable Per-Pathogen Microbiological Response at the EOT and TOC Visits: mMITT Population

    EOT visit: within 24 hours after the completion of the last infusion of study intervention (study treatment was a minimum of 7 days and maximum of 14 days); TOC visit: any day from Day 21 to 25

  • Percentage of Participants With Clinical Cure at the EOT and TOC Visits in Participants With Gram-negative Baseline Pathogens Resistant to Ceftazidime: mMITT Population

    EOT visit: within 24 hours after the completion of the last infusion of study intervention (study treatment was a minimum of 7 days and maximum of 14 days); TOC visit: any day from Day 21 to 25

  • +6 more secondary outcomes

Study Arms (1)

CAZ-AVI

EXPERIMENTAL
Drug: Zavicefta, Ceftazidime-Avibactam

Eligibility Criteria

Age18 Years - 90 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Male or female participants ≥18 and ≤90 years of age.

  • New or worsening infiltrate on chest X-ray obtained within 48 hours prior to screening.
  • Participants have systemic signs and respiratory signs or symptoms of HAP/VAP

You may not qualify if:

  • Previous administration with an investigational drug within 30 days or 5 half lives preceding the first dose of study intervention used in this study (whichever is longer).
  • Acute Physiology and Chronic Health Evaluation (APACHE) II score \>30 or \<10 using the most recent available data.
