PK & Safety Study of Xeruborbactam Oral Prodrug Combined With Ceftibuten in Participants With Renal Impairment
Sponsor:

Qpex Biopharma, Inc.

Brief Summary:

A Phase 1, open-label, single-dose study to determine the safety and pharmacokinetics of ORAvance (ceftibuten/xeruborbactam oral prodrug \[QPX7831\]) in participants with renal impairment

Condition or disease

Bacterial Infections

Intervention/treatment

Xeruborbactam Oral Prodrug

Ceftibuten

Phase

PHASE1

Detailed Description:

Qpex Biopharma, Inc. is developing an oral dosage form that delivers Xeruborbactam, a new boron-based beta-lactamase inhibitor with activity against both serine and metallo-beta-lactamases, for oral treatment in combination with a beta-lactam antibiotic. Ceftibuten is a cephalosporin antibiotic approved in the US for acute exacerbations of chronic bronchitis, acute bacterial otitis media and pharyngitis/ tonsillitis. This is a Phase 1 open-label, single-dose study to assess the safety, tolerability, and PK, of ceftibuten and xeruborbactam oral prodrug given in combination to participants with varying degrees of renal impairment as compared to participants with normal renal function. Objectives: The objectives of the study are: 1. To assess the PK of ceftibuten and xeruborbactam oral prodrug given in combination in participants with varying degrees of renal impairment. 2. To evaluate the safety and tolerability of ceftibuten and xeruborbactam oral prodrug given in combination in participants with varying degrees of renal impairment.
