Overview

Brief Summary

This is a Phase I, open-label, non-randomized, single center study in 48 healthy adult male and female subjects, aged 18 to 45 years. This study is aimed to investigate the safety and pharmacokinetics of ceftazidime-avibactam (AVYCAZ) combined with aztreonam (ATM), AVYCAZ alone, and ATM alone. The study will have 6 arms, arms 1-4 are the single drug administration treatment groups and will include AVYCAZ per label dosing, AVYCAZ as a continuous infusion (CI), ATM per label dosing, and ATM as a CI. Arms 5 and 6 are the two AVYCAZ and ATM combination drug administration treatment groups. The duration of subject participation will be up to 44 days, and the total length of the study will be 15 months. The primary objective of this study is to describe the safety of two dosing regimens of AVYCAZ combined with ATM relative to AVYCAZ alone, and ATM alone in healthy adult subjects.

Arms 5 and 6 are the two AVYCAZ and ATM combination drug administration treatment groups. The duration of subject participation will be up to 44 days, and the total length of the study will be 15 months. The primary objective of this study is to describe the safety of two dosing regimens of AVYCAZ combined with ATM relative to AVYCAZ alone, and ATM alone in healthy adult subjects. The secondary objectives of this study are to; 1) Characterize the PK profiles of two dosing regimens of AVYCAZ combined with ATM, AVYCAZ alone, and ATM alone at the population level in healthy adult subjects; 2) Characterize the PK profiles of two dosing regimens of AVYCAZ combined with ATM, AVYCAZ alone, and ATM alone following initiation of dosing on day 1 in healthy adult subjects; and 3) Characterize the PK profiles of two dosing regimens of AVYCAZ combined with ATM, AVYCAZ alone, and ATM alone following multiple daily dosing in healthy adult subjects.

  • \*\*\*\*Non-childbearing potential is defined as being post-menopausal for at least 18 months or surgically sterile via hysterectomy, bilateral oophorectomy, or tubal sterilization.

Exclusion Criteria

  • History of any clinically significant (CS) disease or disorder, medical/surgical procedure, or trauma within 4 weeks prior to the first administration of study product(s)\*.

  • Known history of a clinically important allergy/hypersensitivity to AVI, any monobactam, any beta-lactam and/or L-arginine.
  • Receipt of probenecid or furosemide within 14 days prior to study enrollment.
  • Receipt of any antibiotics within 14 days prior to study enrollment.
  • Receipt of prescription medications (except birth control pills or hormone replacement in females) within 14 days prior to study enrollment, unless in the opinion of site investigator the medication will not interfere with the study procedures or impact subject safety.
  • Receipt of non-antibiotic medications that interacts with OAT3\*\* within 14 days prior to study enrollment.
