A Drug-Drug Interaction Study Between NTQ5082 Capsules and Midazolam Oral Solutio

This is a single-center, non-randomized, open-label, single-sequence, self-controlled drug-drug interaction study in healthy participants. The main purpose of the study is to evaluate whether a single dose and repeated daily doses of NTQ5082 capsules affect the pharmacokinetics of midazolam oral solution. Midazolam is used in this study as a probe drug to assess the activity of cytochrome P450 3A (CYP3A), an enzyme involved in the metabolism of many medicines. Approximately 18 healthy male and female participants will be enrolled. Participants will receive a single oral dose of midazolam 2 mg on Days 1, 4, and 11. NTQ5082 200 mg will be administered orally once daily from Day 4 through Day 12. Blood samples will be collected to measure the concentrations of midazolam and its metabolite, 1'-hydroxymidazolam, and to calculate pharmacokinetic parameters. The safety and tolerability of midazolam administered alone and together with NTQ5082 will also be evaluated through adverse event monitoring, laboratory tests, vital signs, physical examinations, and electrocardiograms. The study includes a screening and protocol-required vaccination period, an inpatient treatment period, and a safety follow-up telephone call within 7 days after discharge.

Safety and PK of Ceftibuten-ledaborbactam Etzadroxil Fixed-dose Combination

This is a Phase 1, open-label, three-part, study in approximately 96 healthy adult participants between 18 and 55 years of age (both inclusive) (16 participants in Part 1, 20 participants in Part 2 and , and approximately 60 participants in Part 3). The study will be conducted at one clinical site in the United States. Participants in Part 1 and Part 2 may be conducted in parallel. The duration of an individual participation will be approximately 46 days for Part 1 , 43 days for Part 2 and 83 days for Part 3. All participants in Parts I und 2 will be screened within 28 days prior to dosing. All participants in Part 3 will be screened within 33 days prior to dosing. They will be admitted to the clinical research unit (CRU) the day prior to dosing and will remain in the CRU until the end of the PK sample collection period. All participants will return to the clinic for follow-up assessments 7 days ± 1 day after the last dose of study intervention. Participants in Part 3 will also return to the clinic for follow-up assessments 28 days ± 2 days and 42 days ± 2 days after the last dose of study intervention.
