Study of the Absorption, Metabolism, and Excretion of [14C]-Tebipenem Pivoxil Hydrobromide (TBPM-PI-HBr) Following a Single Oral Dose in Healthy Male Subjects
Study Details
Study Description
Brief Summary
The purpose of this study is to determine the absorption, metabolism, and excretion of [14C]-TBPM-PI-HBr and to characterize and determine the metabolites present in plasma, urine, and where possible, feces in healthy male subjects following a single oral administration.

Outcome Measures
Primary Outcome Measures
- Pharmacokinetics (PK) of Tebipenem (TBPM) will be determined following administration of [14C]-TBPM-PI-HBr to healthy male subjects [Day 1 to Day 5]
The primary PK outcome endpoints following oral administration of [14C]-TBPM-PI-HBr will be derived for TBPM in plasma (calculated from whole blood concentrations) based on the concentration-time profile
- Total radioactivity will be determined following administration of [14C]-TBPM-PI-HBr to healthy male subjects [Day 1 to Day 5]
The primary PK outcome endpoints following oral administration of [14C]-TBPM-PI-HBr will be derived for total radioactivity in whole blood and plasma based on the total radioactivity concentration-time profile
Secondary Outcome Measures
- Metabolite profiling and chemical structuring of metabolites in plasma, urine, and, where possible, feces will be determined after a single oral dose of [14C]-TBPM-PI-HBr [Day 1 to Day 5]
The secondary metabolite outcome endpoints will be derived: metabolic profile of TBPM-PI-HBr metabolic profile of TBPM-PI-HBr
- Metabolite profiling and chemical structuring of metabolites in plasma, urine, and, where possible, feces will be determined after a single oral dose of [14C]-TBPM-PI-HBr [Day 1 to Day 5]
The secondary metabolite outcome endpoints will be derived: • identification of the structure of TBPM-PI-HBr metabolites
- The safety and tolerability of a single oral dose of [14C]-TBPM-PI-HBr when administered to healthy male subjects. [Day 1 to Day 5]
The secondary safety outcome measures for this study are as follows: • incidence and severity of AEs
- The safety and tolerability of a single oral dose of [14C]-TBPM-PI-HBr when administered to healthy male subjects. [Day 1 to Day 5]
The secondary safety outcome measures for this study are as follows: •incidence of laboratory abnormalities, based on hematology, clinical chemistry, coagulation, and urinalysis test results
Eligibility Criteria
Criteria
Inclusion Criteria
-
Healthy adult males, of any race, between 18 and 55 years of age, inclusive.

-
Willing and able to provide written informed consent and comply with all study assessments, restrictions, and adhere to the protocol schedule.
-
Medically healthy with no clinically significant medical history, or abnormalities in physical examination, laboratory variables, vital signs or ECG at the time of screening and Check-in, as deemed by the Investigator (or designee).
-
Have suitable venous access for repeated blood sampling.
-
History of a minimum of 1 bowel movement per day.
Exclusion Criteria
-
History or suspicion of routine or chronic drug or alcohol abuse or dependence within 2 years prior to Check-in.
-
Use of tobacco, nicotine, or nicotine-replacement products within 30 days prior to Check-in or planned use during the study.
-
Use or intend to use any medications/products known to alter drug absorption, metabolism, or elimination processes, including St. John's wort, within 30 days prior to Check-in, unless deemed acceptable by the Investigator (or designee).
-
Use/receipt of any prescription or nonprescription medication, herbal products, vitamins or vaccines within 14 days (or 5 half-lives whichever is longer) prior to Check-in, without prior approval from the Medical Monitor.
-
Donation of more than 500 mL of blood or plasma within 56 days prior to Check-in, or receipt of a blood transfusion within 1 year prior to Check-in.
-
Receipt of any other investigational product or participation in another investigational clinical study that included drug treatment within 30 days, or 5 times the t1/2 of the investigational drug, whichever is longer.
-
Have previously completed or withdrawn from this study or any other study investigating TBPM-PI-HBr, and have previously received TBPM-PI-HBr.
-
Subjects with exposure to significant diagnostic or therapeutic radiation (e.g., 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.
-
Subjects who have participated in a radiolabeled drug study where exposures are known to the Investigator within the previous 3 months prior to admission to the clinic for this study or participated in a radiolabeled drug study where exposures are not known to the Investigator within the previous 6 months prior to admission to the clinic for this study. The total 12-month exposure from this study and a maximum of 3 other previous radiolabeled studies within 3 to 12 months prior to this study will be within the CFR recommended levels considered safe, per United States (US) Title 21 CFR 361.1.
-
Subjects who, in the opinion of the Investigator (or designee), should not participate in this study.
