Safety Study of Intravenous Ertapenem in Combination With Zidebactam (WCK 6777)

• Status: Not yet recruiting
• Trial end date: 2023-11-13
• Target enrollment: 0
• Participant gender: All

Summary

This is a Phase 1, single center study to investigate the safety, tolerability, and pharmacokinetics (PK) of three dose-level groups of WCK 6777 (ERT and ZID combination), and two dose-level groups of ERT alone and ZID (WCK 5107) alone in 52 healthy adult male and female subjects aged 18 to 45 years old (both inclusive). Seven treatment cohorts will be evaluated in this study. WCK 6777 will be evaluated in three cohorts - Cohorts 1, 4 and 7- of 8 subjects each (6 study drug combinations and 2 placebos); ERT will be evaluated alone in two cohorts - Cohorts 2 and 5- of 8 subject each (6 ERT and 2 placebos); and ZID will be evaluated in two cohorts, Cohorts 3 and 6, of 6 subjects each (all ZID). The study will be placebo-controlled and double-blinded in all cohorts except Cohorts 3 and 6. No placebo subjects are included in standalone ZID cohorts, since adequate safety data for higher doses of ZID alone in comparison with placebo are available from completed Phase 1 studies of WCK 5107 (ZID) alone and the ZID-only arms of WCK 5222 (cefepime + ZID) studies. The primary objective is to assess the safety and tolerability of three dose-escalating regimens of WCK 6777 ( ERT and ZID combination) and two-dose escalating regimens of standalone ERT or ZID following single daily doses for 7 days in healthy adult subjects.

Criteria

Inclusion Criteria:

1. Provide a signed and dated written informed consent and agrees to comply with the study procedures and length of confinement to the research site.

2. Be able to understand and willing to comply with study procedures, restrictions, and requirements, as determined by the Site Principal Investigator (PI) or authorized clinician(s) (listed on FDA Form 1572).

3. Adults 18 to 45 years of age inclusive, including non-pregnant, non-lactating females.

4. Have suitable veins for cannulation or repeated venipuncture.

5. Be in good general health at the time of enrollment. Note 1: Determined by medical history (MH), medication use, physical examination (PE), vital signs (VS), clinical laboratory tests including estimated creatinine clearance (CLCR) > / = 80 mL/min by the Cockcroft-Gault method, and 12-lead Electrocardiogram (ECG) within reference ranges at Screening and Day-1.

Note 2: Exceptions to Blood Pressure (BP), Heart Rate (HR) and laboratory test values being with normal ranges are:

• Subjects with baseline HR > / = 45 to 50 Beats per Minute (bpm) may be accepted if otherwise healthy adults with known history of asymptomatic bradycardia.

• Subjects with baseline Systolic Blood Pressure (SBP) up to 140 Millimeters of Mercury (mmHg) and Diastolic Blood Pressure (DBP) up to 90 mmHg may be accepted if otherwise healthy.

• A laboratory value that is Grade 1 will be allowed if not considered to be clinically significant by the investigator, with the exception of Alanine Aminotransferase (ALT), Aspartate Aminotransferase (AST), Alkaline Phosphatase (AP), total and direct bilirubin, Blood Urea Nitrogen (BUN), serum creatinine, Creatinine Clearance (CLcr), and urine protein.

6. Sexually active females must be of non-childbearing potential or must use a highly effective method of birth control from screening to 30 days following the last dose of study product.

Note 1: A female is considered of childbearing potential unless post-menopausal (defined as history of > / = 1 year of spontaneous amenorrhea and a Follicle-Stimulating Hormone (FSH) level >40 IU/L), or permanently surgically sterilized.

Note 2: Highly effective contraceptive methods include: (a) surgical sterilization methods, such as tubal ligation, bilateral oophorectomy, salpingectomy, hysterectomy, or successful tubal obliteration (e.g., Essure(R)) with documented radiological confirmation test at least 90 days after the procedure, or (b) long-acting reversible contraception, such as progestin-releasing subdermal implants, copper intrauterine devices (IUDs), levonorgestrel-releasing IUDs.

Note 3: A subject who is not sexually active and abstains from sexual intercourse can be enrolled and abstinence documented.

7. Sexually active males must be vasectomized or agree to use barrier contraception and not donate sperm from first dose of study product until 30 days following the last dose.

Note 1: Barrier contraception includes use of condom with spermicide. Note 2: A subject who is not sexually active and abstains from sexual intercourse can be enrolled and abstinence documented.

8. Subjects must be willing to avoid excessive physical exercise within 48 h prior to dosing until discharge from the CTU on Day 8, and 24 h before the last visit (Day 11 +3 days).

9. No history of acute febrile or infectious illness for at least 7 days prior to the administration of study drug(s).

Exclusion Criteria:

1. Known history of a clinically significant food or drug allergy/hypersensitivity including known allergy/hypersensitivity to Ertapenem (ERT), any ß-lactam drugs or other related drugs.

2. Current seasonal allergies with ongoing symptoms for more than a week prior to dosing requiring glucocorticoids and/or frequent use of antihistamines for treatment.

3. Any history of a chronic condition including renal failure that may increase risk to subject or interfere with endpoint assessment, or any unstable chronic disease.

Note 1: Unstable chronic disease is defined by need for frequent medical interventions that lead to a change in medications and/or required hospitalization, surgery or an invasive procedure or emergency department/urgent care visit, as determined by the Site PI.
