Study of the Metabolism and Excretion of Zidebactam (WCK 5107) Following a Single Intravenous Infusion.

The primary objectives of the study are:

• To determine mass balance and routes of elimination of [zidebactam following administration of a single 1g (approximately 200 μCi) radiolabeled intravenous (IV) infusion of zidebactam in healthy male subjects
• To assess the pharmacokinetics (PK) of a single IV infusion of zidebactam
• To determine the whole blood and plasma concentrations of total radioactivity following a single IV infusion of -zidebactam
• To determine the urinary and fecal recovery of the total administered radioactive dose

The secondary objectives of the study are:

• To characterize and identify metabolites of zidebactam in plasma, urine, and feces, as applicable
• To determine plasma and urine concentrations of non-radiolabeled zidebactam
• To assess the safety and tolerability of zidebactam

Inclusion criteria

• Body mass index between 18.5 and 29.9 kg/m2, inclusive at Screening and Check-in (Day -1).
• In good health, determined by no clinically significant findings from medical history, physical examination (at Check-in [Day -1]), 12-lead ECG, vital signs measurements, and clinical laboratory evaluations (congenital nonhemolytic hyperbilirubinemia [eg, Gilbert's syndrome] is not acceptable) at Screening or Check-in as assessed by the Investigator (or designee).
• Blood pressure between 90 and 140 mmHg systolic, inclusive, and not higher than 90 mmHg diastolic, unless deemed not clinically significant by the Investigator (or designee).
• History of a minimum of 1 bowel movement per day.

Exclusion criteria

• Significant history or clinical manifestation of any metabolic, allergic, dermatological, hepatic, renal, hematological, pulmonary, cardiovascular, gastrointestinal, neurological, respiratory, endocrine, or psychiatric disorder.
• History of significant hypersensitivity, intolerance, or allergy to any drug compound, food, or other substance.
• History of alcoholism or drug/chemical abuse within 1 year prior to Check-in (Day -1).
• Alcohol consumption of >28 units per week for males. One unit of alcohol equals 12 oz. (360 mL) of beer, 1½ oz. (45 mL) of liquor, or 5 oz. (150 mL) of wine.
• Use or intend to use any medications/products known to alter drug absorption, metabolism, or elimination processes, including St. John's Wort, within 14 days prior to Check-in.
• Subjects with exposure to significant diagnostic or therapeutic radiation (eg, serial X-ray, computed tomography scan, barium meal) or current employment in a job requiring radiation exposure monitoring within 12 months prior to Check-in.
