A Single-center, Open-label, Study Evaluating Safety and Pharmacokinetics of Single Doses of Zidebactam-Cefepime and Metronidazole Alone or in Combination.

Completed · Phase 1

Conditions studied: PHA1A

In brief

This is a Phase I, Single-Center, Open-Label study evaluating the safety and pharmacokinetics of single doses of ZID-FEP and metronidazole alone or in combination utilizing a 3-period, crossover study design. Thirty eligible male and female healthy adult subjects will participate in the study and receive single doses of (1) ZID-FEP 3g IV (ZID 1 g plus FEP 2 g) administered over 1 hour (h); (2) metronidazole 0.5 g IV alone administered over 1 h; and (3) metronidazole 0.5 g IV over 1 h, followed by ZID-FEP 3g IV over 1 h over 3 treatment periods separated by a 48 h washout period.

Calculated creatinine clearance ≥90 mL/min (Cockcroft-Gault method).
Computerized 12-lead ECG recording without signs of clinically significant pathology and showing no clinically significant deviation as judged by the Principal Investigator. The QT interval corrected for heart rate using Fridericia's formula must be ≤450 ms for males and be ≤460 ms for females.
Males must agree not to donate sperm and if engaging in sexual intercourse with a female partner who could become pregnant, must agree to use a condom and highly effective method of contraception (see Section 6.6) until 90 days after the last administration of study drug.
Females should not be pregnant or breastfeeding (to be confirmed by a urine pregnancy test at screening with confirmation by a serum pregnancy test at admission) or should be of non-childbearing potential at screening.
Females must be either postmenopausal for at least 1 year, surgically sterile (bilateral oophorectomy or hysterectomy), or practicing one of the acceptable methods of birth control, as defined in inclusion criteria #7, for 3 weeks prior to study drug administration, during the study, and for 90 days after the last administration of study drug.
All values of hematology, serum chemistry, coagulation, and urinalysis showing no clinically significant deviations from the normal range as judged by the Principal Investigator.

You may not qualify if…

Participation in another investigational drug or device study or treated with a study drug within 30 days or 5 half-lives, whichever is longer, before receiving any study drug in this study.
History/evidence of clinically relevant pathology related to the cardiovascular system, central nervous system, respiratory tract, gastrointestinal tract, endocrinology, immunology, hematology or any other systemic disorder/major surgeries, that in the opinion of the Principal Investigator would confound the subject's participation and follow-up in the study.
History of clinically significant food or drug allergy, including known hypersensitivity to cefepime or metronidazole or any other related drugs.
History of Clostridium difficile induced diarrhea or infection within 1 year before screening.
Prior exposure to zidebactam.
Consumed more than 28 units of alcohol per week at any time in the 6 months before study drug administration (1 unit of alcohol is equivalent to 8 ounces of beer, 4 ounces of wine, or 1 ounce of spirits) or history of active alcoholism and/or drug/chemical abuse within the last 3 to 5 years.

Acetaminophen ≤500 mg/day is allowable 3 days before enrollment in the study (Day 1). Should the subject have taken any other medications the Investigator will discuss enrolling the subject with the medical monitor on a case-by-case basis.
Positive serology test for hepatitis B surface antigen, hepatitis C virus or human immunodeficiency virus I/II at screening.

Current use or has used tobacco- or nicotine-containing products (e.g., cigarettes, cigars, chewing tobacco, snuff, etc.) 30 days prior to study drug administration. A cotinine test (with a cut-off of 200 mg) will be performed at screening and at Check-In (Day -1).
Subject has a history of difficulty in providing blood samples or has poor veins which may cause difficulty in obtaining blood samples during the study.
History of bleeding disorders.
Unable or unwilling to follow study instruction or restrictions or a history of the same.
Any other medical, psychological, or social condition which, in the opinion of the Principal Investigator would prevent the subject from fully participating in the study, would represent a concern for study compliance, or would constitute a safety concern for the subject.
