Description détaillée
In Group 1, participants were to receive a total of five oral doses of ceftibuten ledaborbactam etzadroxil (600 mg ceftibuten/600 mg ledaborbactam etzadroxil) every 12 hours. Following the fifth dose, each participant was to undergo one standardized bronchoscopy with bronchoalveolar lavage (BAL) at one of five designated timepoints (2, 4, 6, 8, and 12 hours), with five participants assigned to each timepoint.
In Group 2, participants were to receive a total of five doses of 600 mg oral ceftibuten alone every 12 hours. After the last dose, each participant was to undergo one standardized bronchoscopy with BAL at one of two designated timepoints (4 and 12 hours), with three participants assigned to each timepoint.
Blood samples to determine plasma concentrations of ceftibuten, ledaborbactam etzadroxil (Group 1 only), and urea were to be collected at the designated timepoints.

Intrapulmonary PK - AUC0-12 at Steady State in Group 1: Ceftibuten and Ledaborbactam Etzadroxil
Délai: Samples were taken at 0, 2, 4, 6, 8, and 12 hours post 5th dose
|
The PK parameter AUC0-12 for ceftibuten and ledaborbactam etzadroxil was assessed by standardized bronchoscopy with bronchoalveolar lavage (BAL). BAL samples were collected from each participant at one of five designated time points (2, 4, 6, 8, and 12 hours). The first aspirate was collected separately (BAL 1), while the second through the fourth aspirates were pooled (BAL 2). Mean concentration values at each BAL sampling time point were determined, and data from all sampling times were combined into a single dataset to calculate the AUC0-12 value for each matrix. AUC 0-12 was estimated using Phoenix WinNonlin Non-compartmental analysis. Each participant only contributed one ELF concentration at one time point, so the pharmacokinetic parameters for ELF were calculated using the arithmetic mean concentration at each BAL sampling time point, resulting in a single parameter estimate of ELF across all participants. |

Ratios of Drug Exposure for Ledaborbactam Etzadroxil and Ceftibuten
Délai: Samples were taken at 0, 2, 4, 6, 8, and 12 hours post 5th dose
|
Drug penetration ratio of epithelial lining fluid (ELF) to unbound plasma were assessed using the AUC values for each matrix for BAL 1 and BAL 2. BAL samples were collected from each participant at one of five designated time points (2, 4, 6, 8, and 12 hours). The first aspirate was collected separately (BAL 1), while the second through the fourth aspirates were pooled (BAL 2). All pharmacokinetic parameters (PK) were estimated using Phoenix WinNonlin Non-compartmental analysis. Each participant only contributed one ELF concentration at one time point, so the PK parameters for ELF were calculated using the arithmetic mean concentration at each BAL sampling time point, resulting in a single parameter estimate of ELF across all participants. |
