Phase 1 |
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:
-
To assess the PK of ceftibuten and xeruborbactam oral prodrug given in combination in participants with varying degrees of renal impairment.
-
To evaluate the safety and tolerability of ceftibuten and xeruborbactam oral prodrug given in combination in participants with varying degrees of renal impairment.
Study Design
Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Experimental: Open Label, Single Dose Combination of Ceftibuten & Xeruborbactam oral prodrug 32 participants will be enrolled with varying degrees of renal impairment as well as participants with normal renal function (NRF). 8 participants will be enrolled in each group based on estimated glomerular filtration rate at screening: Group 1: Mild renal impairment (eGFR 60 to 89 mL/min/1.73m2 calculated using the Chronic Kidney Disease Epidemiology Collaboration equation) Group 2: Moderate renal impairment (eGFR 30 to < 60 mL/min/1.73m2 calculated using the CKD-EPI equation) Group 3: Severe renal impairment (eGFR < 30 mL/min/1.73m2 calculated using the CKD-EPI equation) not receiving HD therapy Group 4: Healthy participants with NRF matched to patients in Groups 1, 2 and 3 based on age, gender and BMI All subjects will receive a single dose of ceftibuten & QPX7831 on Day 1. Participants will remain in the clinic until completion of the post-dose procedures on Day 6. Participants will be contacted by phone between Days 8-10 for follow-up. |

Comparison will be performed between the groups for time concentration data measurements (Tmax)
- Area under the plasma concentration versus time curve (AUC) between groups [10 days]
Comparison will be performed between the groups for area under the plasma concentration versus time curve (AUC) Mean graphical presentation of the data will be reported. Statistical analysis of exposure parameters will be performed.
- Urine Pharmacokinetic (PK) amount excreted by subject and by group [10 days]
Urine Pharmacokinetic (PK) parameters such as amount excreted will be calculated from urinary excretion data
- Urine Pharmacokinetic (PK) % dose excreted by subject and by group [10 days]
