Mass Balance Study of [14C]Xeruborbactam (QPX7728) in Healthy Adult Male Participants

Not Applicable
Active, not recruiting
Conditions
ADME
Interventions
Drug: [14C]Xeruborbactam
Registration Number
NCT07083817
Lead Sponsor
Qpex Biopharma, Inc.
Brief Summary

This is a single-dose, phase 1 open-label study to determine the mass balance recovery and metabolic profiling and identification for intravenous (IV) administered \[14C\]xeruborbactam. This study will investigate the primary route of excretion, profile \[14C\]xeruborbactam metabolites in plasma, urine and faeces, and assess the safety, tolerability, and pharmacokinetics (PK) of a single IV dose of \[14C\]xeruborbactam in healthy adult male participants.

Sex
Male
Target Recruitment
8
Inclusion Criteria
  • Male participants who are overtly healthy as determined by medical evaluation including medical history, physical examination, safety laboratory tests, vital signs, and cardiac (12-lead electrocardiogram (ECG)) monitoring.
  • Body weight within 55.0 and 100.0 kg (inclusive) and body mass index (BMI) within the range of 18.0 and 32.0 kg/m2 (inclusive).
  • Participants who have regular bowel movements (ie, average stool production of ≥ 1 and ≤ 3 stools per day)
  • Contraceptive use by participants should be consistent with local regulations regarding the methods of contraception for those participating in clinical studies.
  • Capable of giving signed informed consent
Exclusion Criteria
  • History or presence of significant cardiovascular, respiratory/pulmonary, hepatic, renal, hematological, gastrointestinal (GI), endocrine, immunologic, dermatologic, neurological, or psychiatric disease capable of significantly altering the absorption, metabolism, or elimination of drugs; constituting a risk when taking the investigational intervention; or interfering with the interpretation of data
  • Surgery within the past 3 months prior to Day 1 determined by the investigator to be clinically relevant
  • History of GI surgery including but not limited to, gastric resection and/or intestinal resection that may result in a clinically significant abnormality in GI function (expect for an appendectomy for noncomplicated appendicitis unless it was performed in the previous 12 months)
  • Acute diarrhea, loose stools, or constipation within 14 days prior to the screening visit or upon admission to the clinical research unit (CRU) (Day -1). Diarrhea will be defined as the passage of liquid faeces and/or a stool frequency of ≥ 3 times per day. Constipation will be defined as a failure to open the bowels more frequently than every other day
  • Lymphoma, leukemia, or any malignancy within the past 5 years except for basal cell or squamous epithelial carcinomas of the skin that have been resected with no evidence of metastatic disease for 3 years
