A Phase 1, Open-Label Study in Healthy Adults to Evaluate the Safety and Pharmacokinetics of AVYCAZ(R) in Combination With Aztreonam (COMBINE)
A Phase 1, Open-Label Study in Healthy Adults to Evaluate the Safety and Pharmacokinetics of AVYCAZ(R) in Combination With Aztreonam (COMBINE)
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.

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.
